Coating Shewanella bacteria with silver nanoparticles greatly boosts the performance of biofilm-based microbial fuel cells, researchers report. It achieves this effect by improving the transfer of electrons from the microbe to graphene electrodes in the fuel cells.
The release of formaldehyde and lack of comfort when worn are the downsides to advanced flame-retardant cotton textiles. Researchers at Empa have succeeded in circumventing these issues by developing a chemically and physically independent network of flame retardants within the fibers.
German Chancellor Dr. Angela Merkel visited Berlin-based manufacturer of high-tech laboratory instruments KNAUER Wissenschaftliche Geräte GmbH on Friday, Sept. 10, 2021.
Argonne scientists have observed that when the shape of a thin film of metal oxide known as titania is confined at the mesoscale, its conductivity increases. This finding demonstrates that nanoscale confinement is a way to control quantum effects.
By stabilizing perovskite nanocrystals in a metal-organic framework, a research team has synthesized light-emitting diodes that exploit the performance benefits of the material while avoiding previous roadblocks.
Laser fabrication of nanoparticles offers a powerful and flexible alternative to the purely chemical approaches. In recent years, laser synthesized precious metal nanoparticles are becoming increasingly important in catalysis due to their unique surface features.
A research group in Japan has successfully developed a "nanoporous super multi-element catalyst" that contains 14 elements which are mixed uniformly at the atomic level and used as a catalyst.
Breakthrough in stabilizing nanocrystals introduces a low-cost, energy-efficient light source for consumer electronic devices, detectors and medical imaging.
With the increasingly serious global energy crisis caused by the excessive consumption of fossil fuels, developing clean, efficient, and sustainable energy conversion technologies is highly desirable.
The issue to achieve efficient nitrogen reduction to ammonia has posed a significant challenge for decades as the inert N=N bond could be hardly broken because of the extremely large bond energy of 940.95 kJ mol–1.
