Pores with a Memory

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 ...

Nanostructure boosts stability of organic thin-film transistors

16-Jan-2018

A nanostructured gate dielectric may have addressed the most significant obstacle to expanding the use of organic semiconductors for thin-film transistors. The structure, composed of a fluoropolymer layer followed by a nanolaminate made from two metal oxide materials, serves as gate dielectric ...

Are 20 percent of materials chemistry papers wrong?

18-Dec-2017

Can companies rely on the results of one or two scientific studies to design a new industrial process or launch a new product? In at least one area of materials chemistry, the answer may be yes -- but only 80 percent of the time. The replicability of results from scientific studies has become a ...

Four-stroke engine cycle produces hydrogen from methane and captures CO2

20-Feb-2017

When is an internal combustion engine not an internal combustion engine? When it's been transformed into a modular reforming reactor that could make hydrogen available to power fuel cells wherever there's a natural gas supply available. By adding a catalyst, a hydrogen separating membrane and ...
