Plastic pressure piping is used for many industrial processes, in heating and cooling systems, fire protection installations, gas distribution, and for water supply and distribution.
Potable water applications include cold water services from wells or water mains up to the building as well as hot and cold water distribution piping within buildings.
ABS, PE and PVC materials are all available with 73 F stress rating for use in pressure piping. PE piping is used extensively for cold water service lines and water distribution systems outside the building. Its low temperature flexibility make it especially suited for use in applications where temperature of 35 F and lower will occur.
The maximum temperature at which PE has an HDS rating is 140 F.
Materials with HDS Ratings for Higher Temperatures
Chlorinated Poly (Vinyl Chloride) (CPVC), and cross-linked polyethylene (PEX) materials are available that are rated for long term service at 180 F as well as for cold water applications. Hot and cold water distribution system piping made from these materials has a working pressure rating of 100 psi at 180 F. These systems are tested at 150 psi at 210 F for at least 48 hours to assure integrity at those condition, which may develop in the event the water heater controls malfunction. Thus, such materials are suitable for hot water distribution where water heaters are installed with relief valves set at 150 psi, 210 F.
All plumbing codes require the use of piping having the 100 psi @ 180 F rating for both the hot and the cold water portions of the water distribution system.


Sienna is a leather that has to be touched to be believed. It is made from European cow hides, and delivers the highest aniline quality. This premium leather is drum dyed, waxed and plated. The texture is simply exceptional with natural markings and grain; ready for a patina-rich look. Sienna is a pure aniline leather which has been drum-dyed, waxed and kiss plated in order to achieve an outstanding touch and feel. The leather is as soft as the most expensive and exclusive leather gloves. The Sienna leather is the best of the best and will develop a beautiful patina over time.
All leathers will stretch during use and creasing will eventually occur. This only adds character to the product. Light creases are to be expected as your new furniture is setting in. All materials display this characteristic adding beauty and uniqueness to your piece of furniture. The extent varies depending on cushions and your choice of leather.
Use BoConcept leather care products for protection and apply before use. For general cleaning use only a clean, dry and non-abrasive white soft cloth. If necessary, wipe or lightly rub the entire surface with a clean, soft cloth wrung in soapy water (detergent only). Regularly vacuum under seat cushions using a soft brush nozzle to avoid scratching the surface. Avoid placing furniture in direct sunlight and sources of heat to prevent colour fading.
Contact with alcohol, thinner and benzene/benzole will cause colour and quality deterioration. Also avoid contact with chemical materials such as paints, nail polish or nail polish remover. Jeans and colourful clothes may discolour light leather surfaces.

acoustic lens[ə′küs·tik ′lenz]
a device used to modify the convergence of (that is, to focus) sound beams.
Like optical lenses, acoustic lenses are bounded by two working surfaces. Acoustic lenses are made of a material for which the speed of sound differs from that in the surrounding medium, so that the refractive index n is a number other than unity. In order to attain maximum transmittance, the wave drag of the material should approximate that of the ambient and the viscous losses should be minimal.
Acoustic lenses may be solid, liquid, or gas. In a liquid or gas lens, the lens’s solid casing should exhibit maximum transmittance. For work in liquid media, the material for the lens may be plastic (n = 0.5–0.8), chloroform, or carbon tetrachloride (n = 1.3–1.4). Lenses filled with hydrogen or carbon dioxide are used along with nonhomogenous acoustic lenses filled with pellets or mesh for work in gases (for example, air). Nonhomogeneous diverging air lenses are used to improve the directivity characteristics of loudspeakers. Solid and liquid lenses are used for acoustic images, flaw detection, medical diagnosis, and the concentration of ultrasound for a variety of technological and biological purposes.


Homeowners need to consider many factors before selecting a roofing contractor to maintain or install their roof. When choosing a roofing company, the homeowner should first determine what materials will be used in their roof. Many roofing companies offer a complete service to install a new roof repair a damaged roof and perform routine maintenance. Once the roofing system has been installed, homeowners should regularly inspect the roof for conditions that may cause damage such as leaks, cracks, or broken shingles.
Here Is A Method That Is Helping Green Roofs Vs Asphalt Shingles
Residential roofs are usually constructed of asphalt, clay, concrete, ceramic tile, wood, and steel. Asphalt shingles are the most popular and usually the least expensive roofing option. Other advantages include the durability of the shingles, wide array of styles and colors, and suitability for an array of climates. The cost of installing asphalt shingles is approximately fifty cents per square foot, while fiberglass shingles are approximately three times the price at approximately forty cents per square foot. In addition to the initial installation fee, homeowners should pay one dollar for each year for the life of the roof, or at the very least twice the cost of replacing the roof if it is damaged.
Green roofs are roofs that are made from recycled materials like wood fibers, recycled plastic, and recycled asphalt shingles. A recent trend is to build green roofs with clay tiles or organic material. There are several advantages to having a green roof including low maintenance and increased energy efficiency, however, since it is more expensive to install these roofs they are often not the best choice for residential roofs.

(3) PRODUCT DESCRIPTION Miracote MVERS II is a fluid-applied uniquely modified epoxy moisture mitigation system. It is designed to be used as an above- and below-grade vapor retarder that is placed on the negative side of the concrete substrate. As a vapor emission suppressor, one application of MVERS II will withstand moisture vapor emission rates of up to 10 lbs/1000 sq/ft/24 hrs. Two applications will withstand moisture vapor emission rates of up to 15 lbs/1000 sq/ft/24 hrs. It is recommended for use under impervious non-breathing flooring systems that cannot withstand moisture vapor transmission levels with moisture vapor emissions rates above the floor covering manufacturer‟s recommended levels.


The IMd structural engineer suggested placing so-called panels to span the approx. 5 m between the floors. Consequently beams could be fitted in-between the steel structure, creating a considerable gain in height. They were aware of the smart possibilities the Metsä wooden hollow-core panels could offer.
When using this manner of construction, the floor panels lie between the steel ring girders. In addition to gaining a height of approx. 36 cm, this manner of construction also enables the use of less m². The crux of the placement of these panels lies in the fact that the high quality Kerto® LVL S-ribs are glued constructively to the Kerto® LVL Q upper panel. This creates a strong total to which diaphragm action can be applied. Something that appealed to the IMd structural engineer. The architect acknowledged the rigid structure would guarantee a high level of comfort to the users of the premises.
In addition to the floor construction, with an approx. total height of 390mm, a roof has been erected made of the Finish wooden hollow-core panel.
A sustainable and multi-functional building which can be disassembled and in which the ‘Het Klimbos’ hostel and the nature, environmental and education centre merge seamlessly. The building owes its compactness to a highly implemented double and multiple use of space whereby functions and facilities are shared. Resulting in low building and operating costs on the one hand and a strong synergy between functions and target groups on the other hand.
Imd, together with the architect, made several construction drafts during the design phase regarding sustainability performance in order to attain the lowest ‘overall’ environmental impact. Consequently, the cold-rolled C-profiles were chosen. They are extremely light and use much less material and energy than hot rolled profiles.
Other construction components include wooden laminated beams and wooden, pre-fabricated Kerto® LVL element floors. The wooden rafters from the old, demolished Stayokay will be used to make furniture.
Approx. 20 tonnes of CO2 is stored in the total amount of wood used for the Ripa’s; this is equal to the electricity consumption of 20 households in 1 year (source: NBVT computing module).


A paper published in Science and Technology of Advanced Materials have shown that a synthetic protein called AGMA1 has the potential to promote the adhesion of brain cells in a laboratory setting. It is also cheaper and easier to produce on a large scale. This could help overcome a major challenge in nerve tissue engineering.
Researchers at the University of Milan in Italy have shown that a synthetic protein called AGMA1 has the potential to promote the adhesion of brain cells in a laboratory setting. This could prove helpful in improving cell adhesiveness to biomaterials.
Isolating nerve cells from their original organism and culturing them in the laboratory has long been used as a method to study brain metabolism. It has been challenging, however, to provide brain cell cultures with the necessary “adhesion promoters” that facilitate cell attachment, spreading, growth and morphological development.
Improving cell adhesion to biomaterials is also a major challenge in nerve tissue engineering and is crucial for the development of implanted neural prostheses, such as cochlear implants, and biosensors, such as blood glucose biosensors.
Coating the surfaces of negatively charged cell membranes with positively charged synthetic proteins promotes nerve adhesion and extension in laboratory settings. Most synthetic proteins, however, are toxic to living cells and thus need to be washed off before cell suspensions are spread onto a new plate. They are also unsuitable for applications that are used inside a living organism.
Within the central nervous system, extracellular matrix substances such as collagen and laminin promote the regeneration, differentiation, adhesion and migration of nerve fibers.
A protein sequence found in collagen and laminin has been identified as the minimum sequence that can mediate the adhesion of many cell types, including nerve cells.
AGMA1 is a basic synthetic protein that is biocompatible, water soluble, positively charged, and has a protein sequence similar to that found in collagen and laminin. It is much less toxic to living cells than conventionally used synthetic proteins. AGMA1 is also much easier to prepare on a large scale using relatively low-cost materials. As a result it is much cheaper.
University of Milan scientists tested the potential of AGMA1 to promote the adhesion, proliferation, and differentiation of primary brain cells in the laboratory.
Different primary cell types from rat brain were cultured on AGMA1, and the results compared with those of cells cultured under the same conditions on conventional substrates using other commonly used synthetic proteins. All experimental results showed that the performance of AGMA1 in this respect was comparable to that of conventional substrates.

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...

Cheap Hydrogen from Sunlight and Water
By making a solar photovoltaic material more resilient, researchers may have found a way to make artificial photosynthesis—that is, using sunlight to make fuel—cheap enough to compete with fossil fuels.
If you want hydrogen to power an engine or a fuel cell, it’s far cheaper to get it from natural gas than to make it by splitting water. Solar power, however, could compete with natural gas as a way to make hydrogen if the solar process were somewhere between 15 and 25 percent efficient, says the U.S. Department of Energy. While that’s more than twice as efficient as current approaches, researchers at Stanford University have recently developed materials that could make it possible to hit that goal. The work is described in the journal Science.
One way to make hydrogen using sunlight is to use a solar panel to make electricity and then use that electricity to power a commercial electrolyzer that splits water, forming hydrogen and oxygen. But combining the solar panel and the electrolyzer in one device might be cheaper and more efficient. The electrons produced when light hits a photovoltaic material could facilitate chemical reactions, and the capital costs of one machine would likely be lower than the cost of two (see “A Greener ‘Artificial Leaf,’” “Sun Catalytix Seeks Second Act with Flow Battery,” and “Artificial Photosynthesis Effort Takes Root”).
For some time now researchers have known that you could approach 15 to 25 percent efficiency if you combined two solar cell materials in such a system. One solar cell would power half of the water-splitting reaction—forming hydrogen. The other could form oxygen.
The hydrogen part is pretty much solved now, but researchers have had trouble with the oxygen half. The most efficient solar cell materials for this reaction (silicon, for example) quickly corrode. The Stanford researchers discovered that they could make silicon last for days, rather than just a few hours, by coating it with a protective layer of nickel just two-billionths of a meter thick. The materials split water for three days before the researchers stopped the experiment to examine the materials for damage. They found none.
Other materials—such as metal oxides—can last this long, but they split water very slowly. The new materials are an order of magnitude faster, says John Turner, a research fellow at the National Renewable Energy Laboratory in Golden, Colorado. “Over 40 years of work on oxides has not produced a result like this,” he says.
It could be a while before the materials are used in commercial hydrogen production. To achieve the needed efficiencies, the materials would still need to be incorporated into a system that uses two solar cells. And a big remaining question is how long the materials can last. To be economical, a system would have to run for at least five years, Turner says.

Batteries are an essential part of modern life. Your car, mobile phone, laptop, and camera wouldn't exist without them. And researchers around the world are constantly working to make them better.
That includes a team at the HZB Institute for Soft Matter and Functional Materials, which is part of the Institut Laue-Langevin in Grenoble, France. They've been looking at the materials we use to make batteries and trying to figure out if there are better alternatives.
More specifically, they've been looking at the graphite electrodes that form part of the lithium-ion batteries that power most of our household gadgets. Graphite is used because it's cheap, plentiful and stable. However, it can only absorb a limited number of ions before hitting capacity.
Silicon is one alternative. It's also pretty plentiful on Earth, and it can absorb way more ions than graphite can. But there's a problem - as the ions migrate through the silicon, it disrupts the crystal structure. That leads to the electrode swelling in volume by a factor of three, which is tricky to deal with.
But the HZB team, led by Matthias Ballauff, believes it has a solution. After tracking exactly where the ions absorb in a silicon electrode, they found that majority stick around in a layer about 20 nanometres thick on the surface of the silicon. Only one in 26 penetrate further.
"We were able to precisely track where the lithium ions adsorb in the silicon electrode using neutron reflectometry methods, and also how fast they were moving", said Beatrix-Kamelia Seidlhofer, who carried out the experiments.
That suggests that, by using very thin silicon films, it should be possible to develop batteries with a theoretical capacity six times greater than a lithium-ion battery constructed with graphite electrodes. The significantly thinner electrodes would mean that the volume swelling is easier to handle.
That not only saves on material and energy consumed during manufacture, but we get a better battery out as a result.
The research was detailed in a paper in the journal ACS Nano.

Metalix produces two ranges of coil coated non stick bakeware ;
a) Just cook (Single coating)
b) (Two coatings)
Metalix procures its non stick coil coated steel from Corus steel in the United Kingdom. There are very few coil coated plants remaining in the world and other than the two manufacturing plants in the UK, there remain only a few facilities in the USA. China does not possess any coil coating non stick bakeware manufacturers all their manufacturers use the spray method.
Coil coated non stick bakeware is more effective (release properties) and lasts longer than the Silicone Spray bakeware. It is more environment friendly whilst spray bakeware is far more detrimental to the environment. Metalix does not supply spray coated bakeware in any of it current range of product.
Coil coating is a highly automated, efficient, continuous method of applying nonstick coatings to metal, and is used to coat almost all fluropolymer nonstick bakeware as well as significant quantities of cookware, small appliance and industrial parts.
The coil coating process was developed in the early 1960’s. Nonstick coatings were first applied using this process in the early 1970’s, when non stick bakeware began to be recognized as a superior replacement for tinplate bakeware.
Since the early days Whitford has dedicated considerable research and development effort to develop an entire series of products which are suitable for application by coil coating. These products range from the very beat (QUANTUM ™; an internally reinforced coating) to more economical coatings (XYLAN: easy clean) and a wide choice in between
Coil Coating vs Silicone Spray Systems
Silicone Spray Systems
History: Silicone spray bakeware products are making a reappearance in the UK and mainland Europe because of the lower cost of production.
Some years ago spray was virtually wiped out due to the superior quality of pre-coated products.
Origin: Products are arriving from production facilities that are normally based in China.
Range: Differentiation potential is significantly reduced, with finishes only available in either metallic black or pewter.
Normally products are restricted to one colour for both the interior and exterior.
|A. Coil applied PES/PTFE Substrate is ECCS, a packaging Grade metal with all food Contact approvals.||A. Silicone spray products are normally applied to simple cold rolled mild steel lower quality.|
|B. Coil applied PES/PTFE coatings are applied directly to the substrate without the need for cleaning or pre-treatment.||B. To Obtain adhesion of the coating to the substrate, it is necessary to clean, and either apply a pre-treatment system or Mechanically abrade the Substrate surface.|
|C. ECCS has some corrosion resistance when exposed to moist air.||C. When exposed to air cold rolled mild steel will corrode in moist conditions.|
Application of coil coatings is extremely efficient, with usage normally in excess of 95%.
Spray application can lead to large amounts of over spray leading to much higher usage levels.
Coil applied products are extremely uniform in terms of film thickness
Spray requires automatic application to give consistent coating thickness.
Coil applied coatings in the UK are subject to strict waste management practices (EN14001 & IPPC)
Spray releases VOC’s into atmosphere.
Bakeware Product Performance
A comparison of silicone spray products verses coil applied PES/PTFE products in Corus laboratories has found:
- Stain resistance of coil applied is superior.
- Temperature resistance of coil applied is superior.
- Fat and oil resistance of the coil applied product is superior.
- Durability of release performance for coil applied is superior.
- Abrasion resistance of the coil applied is normally superior.
- Inclusion and debris counts much lower in coil applied products.
Together with the concern the rtetailer has for the environment, Metalix ,by using only coil coated product is making its mark on by contribution to reducing volatile organic compounds (VOC’s) to zero in the production of its bakeware. VOC’s are carefully controlled during the coil coating application process and oxidize before releasing to the atmosphere through efficient extraction in a controlled environment. The coil coated steel product purchased from Corus Steel in the UK and used in the manufacture of Metalix bakeware is all manufacture in the UK, to UK and European environmental legislation.
Spray coatings tend to be not as efficient in their application with a considerable amount of overspray and wasted coatings which results in harmful VOC’s escaping into the atmosphere. It is recorder that as much as ……………………………………………….
The environmental table below demonstrated the environmental impact of coil vs spray bakeware.
|Coil Coating||Spray Coating|
⁺ Coil Coating process >95% efficient
⁺ Solvents incinerated as part of process and energy used to re-heat curing ovens
⁺ Emissions of VOC’s regulated by law (<50mg/m3) ⁺ Uniformity of coating thickness & application ⁺ Unused paint easily controlled & re-used ⁺ Flexibility in top and reverse coat colour ⁺ ECCS substrate used has full FDA approval for use with food and has good corrosion resistance
― Typical 70% efficiency
― Typical fume extraction can mean release of VOC’s into atmosphere
―Without incinerator up to 300mg/m3
―Variable paint thickness and finish
―Typical 30% waste in overspray
―Typically pewter and black only
―Typically manufactured or CR and other low cost substrates with poorer corrosion resistance

What the heck is A CERAMIC? GIVE Samples of Fashionable ENGINEERING CERAMIC. Speak about The particular Merits AND Disadvantages
The only indicates to refer to ceramic components appreciates that they’re neither natural and organic nor metallic. Ceramics present glassy, crystalline or manifest equally houses. Ceramics are in essence difficult materials which are chemically non-reactive densified or fashioned beneath intensive heat conditions.
It can be essential to remember that ceramics appertain to more than dishes or pottery. Contemporary applications of ceramics not only involve the manufacture of perfect dishes and pottery but digital parts too. Offered that current societies are intensely depending on electric vigor and electronic products supports the significance of ceramic supplies immediately. Ceramics supplies are basic towards progressive progress of electronic material gadgets as various compositions help for ideal electronic and electrical characteristics like ferroelectric, superconducting, semiconducting and insulator homes. To further more appraise, the performance of ceramic material applications, is they will also be used in the manufacture of fiber optic components, spark plugs, house shuttle tiles, braking plates, cooktops, chemical sensors, whole body armor, skis, and micro-positioners. As such, the many multiple purposes of ceramics might be attributed inorganic compositions.
Ceramic materials incorporate both equally nonmetallic and metallic elements and as such, encompass distinct inorganic rules many of which consist of nitrides, carbides, borides, and oxides. Metallic oxides like ferrous oxide and aluminum oxide are commonly identified in ceramic elements. It happens to be very important to treasure that there is a wide array of ceramic elements with other compounds that come with carbides, porcelain, porcelain, brick, glass, also as refractory items. It is critical to observe that these former courses of ceramic elements are known as common ceramic elements.
Ceramic supplies have distinctive homes founded about the various compounds inside their composition. Granted that various factors pinpoint the nature of ceramic materials, then, it can be integral to note that alternative ceramic compositions present varying structural qualities.
Considering that the start for the early 20th Century, substantial scientific and engineering-oriented analysis have been conducted while using the goal of tolerating extraordinary environments regularly discovered in diverse engineering fields which contain area exploration at the same time as nuclear stamina in order to name just a few.
The contemporary researching endeavors about ceramic application involving engineering purposes that in many occasions comprise of the telecommunications and electronic industries. These industries require many gadgets which might be worried about energy conversion, harvesting, and storage, catalysts also as sensors. It happens to be also very important to indicate the electromotive is highly dependent on present and rising ceramics systems. Provided the large application of ceramics from the navy components community, programs of ceramics know-how are significantly evolving into plain in the present modern society.
As much as ceramics have specific qualities, most of the roles they perform in active engineering functions require chopping the great expenses of pollution commonplace at this time. As a result, the features attributed to air pollution regulate are understood to your exceptional measure using ceramics engineering. For instance, the attributes of light-weight components allow the automotive field to manufacture elements that can be not merely lightweight but in addition represent some fabulous applications like in automotive engineering. Most of the pros affiliated with ceramic engineering consist of the brittle nature of ceramic compounds, diminished ductility, inadequate tensile qualities, and as such, are vulnerable to the wide array of structural stresses. This means that in search of to form or perhaps machine may, in essence, be out of the question resulting in more losses in personal methods utilized in furthering ceramics engineering.


Torrefaction is the thermal pretreatment of biomass at temperatures of 200-300 °C in an inert atmosphere with the objectives of improving resistance to biodegradation, reducing hydrophilicity, improving grindability and increasing energy density. In this work, we studied the effect of torrefaction temperature (240-280 °C) on the chemistry of birch wood. The samples were from a pilot plant at ECN, and in that way, they were representative of industrially produced samples. We have measured the concentration of hemicellulose and cellulose; changes in the extractives content and composition; and in the lignin structure. We used acid methanolysis and acid hydrolysis for hemicellulose and cellulose analysis, respectively; Klason lignin method, 13C CP-MAS NMR, Dipolar Dephasing NMR, and Py-GC-MS analysis for lignin characterization; and acetone extraction, HPSEC, GC-FID, and GC-MS analysis for extractives characterization. The results provide a more complete picture of the chemical changes in wood by torrefaction.
