08/07/2020MIT researchers have developed a process to manufacture and integrate 'artificial atoms,' created by atomic-scale defects in microscopically thin slices of diamond, with photonic circuitry, producing the largest quantum chip of its type.
08/07/2020The way graphene interacts with other materials depends on how these materials are brought into contact with the graphene. The appropriate atoms are brought into contact with the graphene in such a way that they 'grow' on the graphene in the desired crystal structure. Until now the mechanisms of the 'growth' of such other materials on graphene have often remained unclear.
07/07/2020Scientists from the University of Nottingham have developed a new way to control harmful fungi, without the need to use chemical bioactives like fungicides or antifungals.
07/07/2020Components made of glass- and carbon- fiber reinforced composites, soaring in high-performance applications, can be 3D printed. A team of researchers from NYU Tandon School of Engineering found that the printer head toolpaths are easy to reproduce - and therefore steal - with machine learning (ML) tools applied to the microstructures of the part obtained by a CT scan.
06/07/2020A new North Carolina State University study finds that a material made of carbon nanotubes has a combination of thermal, electrical and physical properties that make it an appealing candidate for next-generation smart fabrics.
06/07/2020Empa researchers have succeeded in applying aerogels to microelectronics: Aerogels based on cellulose nanofibers can effectively shield electromagnetic radiation over a wide frequency range - and they are unrivalled in terms of weight.
03/07/2020Researchers at the Department of Energy's Oak Ridge National Laboratory and the University of Tennessee, Knoxville, are advancing gas membrane materials to expand practical technology options for reducing industrial carbon emissions.
02/07/2020Solar cells based on perovskite compounds could soon make electricity generation from sunlight even more efficient and cheaper. The laboratory efficiency of these perovskite solar cells already exceeds that of the well-known silicon solar cells. Scientists have found microscopic structures in perovskite crystals that can guide the charge transport in the solar cell.
02/07/2020The UN's 3rd Global eWaste Monitor reports 53.6 million metric tonnes (Mt) of e-waste was produced last year -- substantially more than the weight of all adults in Europe. Global e-waste has risen 21% by weight in just five years, fueled by higher consumption rates of electric and electronic equipment, short life cycles, and few repair options.
01/07/2020The synthesis of silica particles, used in bioimaging and drug delivery, could become considerably cheaper and more efficient by adopting a new flow synthesis method demonstrated by researchers in Australia and China, which involves a spiral channel and simple Teflon pipe to promote the rapid mixing of precursor fluids.
