A technique that introduces carbon-hydrogen molecules into a single atomic layer of the semiconducting material tungsten disulfide dramatically changes the electronic properties of the material, according to Penn State researchers at Penn State who say they can create new types of components for energy-efficient photoelectric devices and electronic circuits with this material.
In a new study from the US Department of Energy's Argonne National Laboratory, researchers used the power of artificial intelligence and high-performance supercomputers to introduce and assess the impact of different configurations of defects on the performance of a superconductor.
Researchers at the University of Cincinnati have developed a new test that can easily and simply measure common stress hormones using sweat, blood, urine or saliva. Eventually, they hope to turn their ideas into a simple device that patients can use at home to monitor their health.
The formation and thickening of internal and surface barriers during battery charge and discharge cycles limits electrochemical reactions in a lithium-ion battery with an iron oxide electrode.
A UC Riverside-led team has discovered two Jupiter-sized planets about 150 light years away from Earth that could reveal whether life is likely on the smaller planets in other solar systems.
This Hubble image stars Messier 90, a beautiful spiral galaxy located roughly 60 million light-years from the Milky Way in the constellation of Virgo (the Virgin). The galaxy is part of the Virgo Cluster, a gathering of galaxies that is over 1,200 strong. Messier 90 is remarkable; it is one of the few galaxies seen to be traveling toward the Milky Way, not away from it.
Aluminum is one of the most promising materials for aeronautics and automobile industry. Scientists from the National University of Science and Technology 'MISIS' found a simple and efficient way of strengthening aluminum-based composite materials. Doping aluminum melt with nickel and lanthanum, scientists managed to create a material combining benefits of both composite materials and standard alloys: flexibility, strength, lightness. The article on the research is published in Materials Letters.
An international research group has improved graphene's ability to catalyze the 'hydrogen evolution reaction,' which releases hydrogen as a result of passing an electronic current through water. They designed a mathematically predicted graphene electrocatalyst, and confirmed its performance using high resolution electrochemical microscopy and computational modelling. The findings were published in the journal Advanced Science.
As indicated by a recently published study, short-term opioid use shifts a range of emotional responses to the positive direction. This may be one of the reasons behind the onset of opioid use disorder.
A new study indicates that PSA, a prostate cancer marker, is one of the catalysts that activate vascular endothelial and lymphangiogenic growth factors which contribute to the spread of cancer.
