Inspectors find phthalates in toys and asbestos in second-hand products

Hundreds of consumer products with illegal amounts of restricted chemicals

13-Feb-2018

The project report shows a relatively high number of products on the European market containing chemicals that are restricted under REACH. Inspectors in 27 European countries checked 1 009 mixtures, 4 599 articles and 17 substances. Overall, out of 5 625 targeted product checks, 18 % did not ...

Printable, colorful camouflage with polymers

13-Feb-2018

In nature, colors can serve as a form of communication, but they can also hide animals and plants, camouflaging them from sight. Researchers now report that they have developed polymers that can better mimic nature's color-changing abilities than existing polymers. They say the materials could ...

Porous polymer films with shape memory

08-Feb-2018

Whether for separation processes, photovoltaics, catalysis, or electronics, porous polymer membranes are needed in many fields. Membranes with micropores that switch between different shapes and/or sizes would expand the possibilities. Scientists have introduced a process that produces porous ...

Silk fibers could be high-tech 'natural metamaterials'

05-Feb-2018

New research has demonstrated how the nano-architecture of a silkworm's fiber causes "Anderson localization of light," a discovery that could lead to various innovations and a better understanding of light transport and heat transfer. The discovery also could help create synthetic materials and ...

Photoreversible molecular switch changes the physical property of thermoresponsive polymer

05-Feb-2018

Researchers have developed a novel strategy to control the shapes of polymeric materials by utilizing photoresponsive molecular switches, which may evolve tractable stimuli-responsive soft materials. Ionic liquids (ILs) are liquid-state salts at room temperature and are high-potential materials ...

A 3-D printed shape-shifting smart gel

01-Feb-2018

Rutgers engineers have invented a "4D printing" method for a smart gel that could lead to the development of "living" structures in human organs and tissues, soft robots and targeted drug delivery. The 4D printing approach here involves printing a 3D object with a hydrogel (water-containing gel) ...

3-D printing improves cell adhesion and strength of PDMS polymer

25-Jan-2018

Combining two different polymer forms can switch manufacturing of silicone parts from molding, casting and spin coating of simple forms to 3-D printing of complex geometries with better mechanical characteristics and better biological adhesion, according to a team of Penn State researchers. "So ...

Bio-renewable process could help 'green' plastic

23-Jan-2018

When John Wesley Hyatt patented the first industrial plastic in 1869, his intention was to create an alternative to the elephant tusk ivory used to make piano keys. But this early plastic also sparked a revolution in the way people thought about manufacturing: What if we weren't limited to the ...
