Method safely produces colour-changing shear films

Method safely produces colour-changing shear films
Anyone who has a rear-view mirror that automatically dims blue in reaction to annoying high-beam headlights glaring from behind has seen an electrochromic film in action. Now, chemists at the Georgia Institute of Technology have developed a new method to more safely and, by extension, easily produce these shear films, which change their colour with the help of a tiny electric current. This could make them available to many industries that have not been able to feasibly use them before.

Nanomaterials help spiders spin the toughest silk

Nanomaterials help spiders spin the toughest silk
Spiders’ silk is already tough stuff – just ask your friendly neighbourhood Spiderman. But now, researchers in Italy and the UK have found a way to make Spidey’s silk a lot stronger, using various different spider species and carbon nanotubes or graphene. The research team, led by Professor Nicola Pugno at the University of Trento, Italy, succeeded in having their spiders produce silk with up to three times the strength and ten times the toughness of the regular material.

One Component Elastomeric Primer/Adhesive System

One Component Elastomeric Primer/Adhesive System
Master Bond has developed X21Med for priming and bonding polyolefinic substrates. It is a single component elastomeric compound that passes ISO 10993-5 tests for cytotoxicity. According to Masterbond, this specialty system was designed to be used as a primer that would promote adhesion between polyolefins and other surfaces such as metals, ceramics, composites and other kinds of plastics. Surfaces primed with X21Med are compatible with a wide variety of adhesives and it can also be used to bond two polyolefin materials.

Semiconductor materials exceed silicon’s powers

Semiconductor materials exceed silicon’s powers
The next generation of feature-filled and energy-efficient electronics will require computer chips just a few atoms thick. For all its positive attributes, trusty silicon can’t take us to these ultrathin extremes. Now, electrical engineers at Stanford have identified two semiconductors – hafnium diselenide and zirconium diselenide – that share or even exceed some of silicon’s desirable traits, starting with the fact that all three materials can “rust.”

Smart windows change from clear to dark in under a minute

Smart windows change from clear to dark in under a minute
Stanford University engineers have developed dynamic windows that can switch from transparent to opaque or back again in under a minute, a significant improvement over dimming windows currently being installed to reduce cooling costs in some buildings. Stanford engineers have built a smart window that quickly changes from clear to dark and back again depending on the light.

Non-hazardous resins are safe

Non-hazardous resins are safe
Robnor ResinLab has just announced two safety-focused resins. The GR100 and GR200 are both non-hazardous and have hazard free labelling and, according to the company, they are the safest resins ever manufactured by the formulator. Free from Isocyanate or Plasticiser, Robnor ResinLab materials GR100 and GR200 have been designed as an alternative option to polyurethanes for applications such as potting, encapsulation and cable jointing.

Packaging protects against corrosion during shipping

Packaging protects against corrosion during shipping
Cortec’s VpCI packaging solutions use vapor phase corrosion inhibiting technology to safeguard metal components during shipping when extreme humidity changes can put metals at risk for corrosion. During the export journey, metal parts need corrosion protection from extreme environmental conditions and humidity swings. Electronics and items like expensive high tech medical diagnostic equipment such as MRIs or ultrasounds are  devices that could benefit from corrosion protection.

Thermal protection material comes in easy-to-use format

Thermal protection material comes in easy-to-use format
A range of soft-PGS (Pyrolytic Graphite Sheet) thermal interface material from Panasonic is now available at RS Components. The material provides excellent thermal protection in an easy-to-use format that makes it ideal for delivering thermal management and heatsinking in applications where space is limited.

Self-assembly process made possible with X-ray synchrotron

Self-assembly process made possible with X-ray synchrotron
Some of the world’s tiniest crystals are known as “artificial atoms” because they can organise themselves into structures that look like molecules, including “superlattices” that are potential building blocks for novel materials. Now scientists from the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University have made the first observation of these nanocrystals rapidly forming superlattices while they are themselves still growing.

High temperature thermal fluids

High temperature thermal fluids
Global Heat Transfer, has released four new Globalthermproducts designed for use in high temperature applications in pharmaceutical and plastic processing sectors. Globaltherm L, N, S and C operate at the temperature ranges typically found in pharmaceutical and plastic processing applications. The non-corrosive fluids are custom-made for use in processes that require stable media that works at higher temperatures for prolonged periods without premature degradation of the fluid.
