Researchers have produced a cost-effective catalyst material for fuel cells using a new preparation process which they analysed in detail. It consists of iron-nitrogen complexes embedded in tiny islands of graphene only a few nanometres in diameter.
Scientists have built a flexible nanogenerator out of cellulose, an abundant natural material, that could potentially harvest energy from the body - its heartbeats, blood flow and other almost imperceptible but constant movements.
Researchers have reported results correlating the flake merging angle with grain boundary (GBs) properties, and proven that increasing the merging angle of GBs drastically improves the flow of electrons.
A recent study reveals that the photovoltaic performance in organic solar cells can be influenced by fullerene stereomer, implies that the stereomeric effect should be envisaged if new fullerene derivative was designed as electron acceptor.
Plant, yeast, even mammalian cells could be engineered into living detectors of virtually any molecule of interest to improve environmental monitoring, metabolic production of pharmaceuticals, and more.
Researchers show that by means of a novel magnetoresistive effect, it is now possible to study the spin transport properties in these materials without the need to fabricate complex devices and/or involve interfaces between different materials.
