Pressure-induced 2D-3D conversion in hybrid lead iodide layered perovskite
Hydrostatic pressurization can lead to new and improved material properties. However, most novel material properties are only retainable at high-pressure states, and therefore have no practical applicability at ambient conditions....
Molecular additives enhance mechanical properties of organic solar cell material
Organic solar cells are ideal for use in flexible electronics because of the inherently malleable nature of semiconducting polymers. Recent research on the interplay between processing, thermodynamics and mechanical stability...
Nanocrystals from recycled wood waste make carbon-fiber composites tougher
Polymers reinforced with ultra-fine strands of carbon fibers epitomize composite materials that are "light as a feather and strong as steel," earning them versatile applications across several industries. Adding materials...
Nanocrystals from recycled wood waste make carbon-fiber composites tougher
Researchers have used a natural plant product, called cellulose nanocrystals, to pin and coat carbon nanotubes uniformly onto the carbon-fiber composites. The researchers said their prescribed method is quicker than...
Army testing new air defense system, laser weapons
The Army is evaluating new air and missile defense systems -- and testing laser weapons -- after postponing some tests due to COVID-19.
Stack and twist: Physicists accelerate the hunt for revolutionary new materials
Scientists have taken an important step towards understanding the interaction between layers of atomically thin materials arranged in stacks. They hope their research will speed up the discovery of new,...
Class ring from 1930s found in car about to be crushed
A class ring from the 1930s was found inside a car that was about to be crushed at an Oklahoma scrap yard, and the item was returned to its original...
Physicists accelerate the hunt for revolutionary artificial atomic materials
Scientists at the University of Bath have taken an important step towards understanding the interaction between layers of atomically thin materials arranged in stacks. They hope their research will speed...
Optics research demonstrates waveguides that guarantee stable propagation of azimuthons
The optical vortex plays an increasingly important role in optical information processing. As an information carrier, it improves the capacity of channels and offers an independent aspect for analysis—different from...
Storing energy in red bricks
Red bricks -- some of the world's cheapest and most familiar building materials -- can be converted into energy storage units that can be charged to hold electricity, like a...
A new way to fabricate MXene films that block electromagnetic interference
Chemical and biomolecular engineers have demonstrated a novel approach to MXene fabrication that could lead to methods for at-scale production of MXene freestanding films: drop-casting onto prepatterned hydrophobic substrates. Their...
Textron to supply 2 Cessna Grand Caravan aircraft to Rwanda
Textron announced Tuesday that it has received a contract to supply two multi-mission Cessna Grand Caravan aircraft for the Rwanda Defense Force.
Recipe for success -- interaction proteomics become a household item
A research team introduces a new optimized and integrated interaction proteomics protocol that combines two state-of-the art methods to allow rapid identification of protein-protein interactions and more.
X-rays indicate that water can behave like a liquid crystal
Scientists have discovered that water can exhibit a similar behavior like a liquid crystal when illuminated with laser light. This effect originates by the alignment of water molecules, which exhibit...
U.S., Japanese militaries conduct training exercise with B-1 bomber, Reagan Strike Group
The USS Ronald Reagan Carrier Strike Group conducted a bilateral mission with a B-1B Lancer and aircraft from Japan's Air Self-Defense Force near Japan last week, according to the Air...
How airplanes counteract St. Elmo's Fire during thunderstorms
A new study finds windy conditions can weaken St. Elmo's fire, the phenomenon when electrically conductive structures spontaneously emit a flash of blue light, when it's generated by aircraft and...
Physicists cast doubt on neutrino theory
Physicists are raising doubts about the existence of an exotic subatomic particle that failed to show up in twin experiments.
NATO receives 2nd Airbus A330 for fleet of multi-role aircraft
NATO received the second plane in a fleet of multi-role aircraft it's assembling this week.
Long-term risks of joint implants
Using highly complex analytical techniques, a group of researchers were able to observe in detail how different metals are released from joint implants and accumulate in the surrounding bone tissue....
X-rays indicate that water can behave like a liquid crystal
Scientists at Stockholm University have discovered that water can exhibit a similar behavior to that of a liquid crystal when illuminated with laser light. This effect originates by the alignment...
A new way to fabricate MXene films that block electromagnetic interference
The proliferation and miniaturization of electronics in devices, wearables medical implants and other applications has made technologies for blocking electromagnetic interference (EMI) especially important, while making their implementation more challenging....
Car passengers can reduce pollution risk by closing windows and changing route
Drivers and passengers can inhale significantly lower levels of air pollution by setting their vehicle's ventilation systems more effectively and taking a 'cleaner' route to their destination, a new study...
Investigating a thermal challenge for MOFs
To the naked eye, metal organic frameworks (MOFs) look a little like sand. But if you zoom in, you will see that each grain looks and acts more like a...
Look: Emu captured after five days on the loose in England
An emu that escaped from her owner's property in England has been captured after wandering loose for nearly a week.
