UB aerospace engineer James Chen publishes a paper that extends classical kinetic theory into high-speed aerodynamics, including hypersonic speed, which begins at 3,836 mph or roughly five times the speed of sound. The new study and others by Chen in influential academic journals attempt to solve long-standing problems associated with high-speed aerodynamics.
A Purdue University team created a method for applying a designer surface-active agent to the surface of a metal to make it easier to cut and shape the material into parts and pieces.
A new tungsten-based alloy developed at Los Alamos National Laboratory can withstand unprecedented amounts of radiation without damage. Essential for extreme irradiation environments such as the interiors of magnetic fusion reactors, previously explored materials have thus far been hobbled by weakness against fracture, but this new alloy seems to defeat that problem.
During the Vietnam War, United States aircraft sprayed more than 20 million gallons of herbicides, including dioxin-contaminated Agent Orange, on the country's rain forests, wetlands, and croplands. A new article from the University of Illinois and Iowa State University documents the environmental legacy of Agent Orange in Vietnam, including hotspots where dioxin continues to enter the food supply.
Hiding an object from heat-sensing cameras could be useful for military and technology applications as well as for research. Efforts to develop such a method have been underway for decades with varying degrees of success. Now, researchers report in ACS Nano that they have fabricated an inexpensive, easy-to-produce film that makes objects completely invisible to infrared detectors.
Researchers from the University of California, Irvine and the University of California, Riverside have uncovered the possibility of an acoustic side-channel attack on the DNA synthesis process, a vulnerability that could present a serious risk to biotechnology and pharmaceutical companies and academic research institutions.
Inspired by the refined electrochemistry of electric car batteries, scientists have developed a battery-like system that allows them to make potential advancements for the manufacturing of medicines. Their new method avoids safety risks associated with a type of chemical reaction known as dissolving metal reduction. Their method would offer significant advantages over current methods of chemical manufacturing, but until now, has largely been sidelined due to safety considerations.
An interdisciplinary team of researchers at NRL and the Air Force Research Laboratory have developed a way to directly write quantum light sources, which emit a single photon of light at a time, into monolayer semiconductors.
Counter to a lot of public opinion, having a mental illness does not necessarily make a person more likely to commit gun violence. According to a new study, a better indicator of gun violence was access to firearms.
By bombarding an ultrathin semiconductor sandwich with powerful laser pulses, physicists at the University of California, Riverside, have created the first 'electron liquid' at room temperature. The achievement opens a pathway for development of the first practical and efficient devices to generate and detect light at terahertz wavelengths -- between infrared light and microwaves. Such devices could be used in applications as diverse as communications in outer space, cancer detection, and scanning for concealed weapons.
