Scientists develop first fabric to automatically cool or insulate depending on conditions

19/02/2019

Researchers at the University of Maryland have engineered a new fabric from synthetic yarn with a carbon nanotube coating that is activated by temperature and humidity, releasing heat in warm humid conditions and trapping heat when conditions are cool and dry.

Tiny fibers create unseen plastic pollution

18/02/2019

While the polyester leisure suit was a 1970s mistake, polyester and other synthetic fibers like nylon are still around and are a major contributor to the microplastics load in the environment, according to a Penn State materials scientist, who suggests switching to biosynthetic fibers to solve this problem.

Researchers discover anti-laser masquerading as perfect absorber

15/02/2019

Researchers at Duke University have discovered that a perfect absorber of electromagnetic waves they described in a 2017 paper can easily be tweaked into a sort of 'time-reversed laser' known as a coherent perfect absorber (CPA).

Novel electrocatalyst outperforms platinum in alkaline hydrogen production

13/02/2019

A novel ruthenium-based catalyst developed at UC Santa Cruz has shown markedly better performance than commercial platinum catalysts in alkaline water electrolysis for hydrogen production. The catalyst is a nanostructured composite material composed of carbon nanowires with ruthenium atoms bonded to nitrogen and carbon to form active sites within the carbon matrix.
