Solar energy researchers are shining their scientific spotlight on materials with a crystal structure discovered nearly two centuries ago.
University of Wisconsin-Madison engineers have made it possible to remotely determine the temperature beneath the surface of certain materials using a new technique they call depth thermography. The method may be useful in applications where traditional temperature probes won't work, like monitoring semiconductor performance or next-generation nuclear reactors.
A 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.
Researchers 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.
Empa 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.
Japanese scientists have elucidated the mechanism of the hydrodynamic power generation using spin currents in micrometer-scale channels, finding that power generation efficiency improves drastically as the size of the flow is made smaller. They experimentally demonstrated the fluid power generation phenomenon in the laminar flow region and confirmed that in the laminar flow region, energy conversion efficiency was increased by approximately 100,000 times.
The 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. In 2030 the world is projected to produce about 50% more e-waste per capita compared with 2014.
New research by Carnegie's Olivier Gagné and collaborator Frank Hawthorne of the University of Manitoba categorizes the causes of structural asymmetry, some surprising, which underpin useful properties of crystals, including ferroelectricity, photoluminescence, and photovoltaic ability.
Tiny diamond crystals could be used as an incredibly sensitive and small gravitational detector capable of measuring gravitational waves, suggests new UCL-led research.
The application of zinc oxide layers in industry is manifold and ranges from the protection of degradable goods to the detection of toxic nitrogen oxide gas. Such layers can be deposited by atomic layer deposition (ALD) which employs typically chemical compounds, or simply precursors, which ignite immediately upon contact with air, i.e. are highly pyrophoric. An interdisciplinary research team at Ruhr-Universität Bochum (RUB) has now established a new fabrication process based on a non-pyrophoric zinc precursor t
