Collision experiments for understanding molecular interactions at the individual particle level
Collision experiments provide the means for a detailed understanding of molecular interactions at the individual particle level. Theoretical and experimental physicists within the Institute for Molecules and Materials have published...
Doomsday prepping in the age of coronavirus
Nestled among Kansas cornfields in a landscape devoid of any noticeable natural topography, a verdant mound can be seen from a dirt road. Surrounded by a military-grade chain fence and...
How interstitial ordering affects high-strength steels
The performance of materials is strongly influenced by their alloying elements: Adding elements beyond the basic composition of the alloy can strongly influence the properties and performance of it. In...
Famous birthdays for May 14: Rob Gronkowski, Sofia Coppola
Football player Rob Gronkowski turns 31 and filmmaker Sofia Coppola turns 49, among the famous birthdays for May 14.
Solid-ion conductors for safer batteries
Lithium metal is one of the most promising candidates for next generation battery anodes due to its exceptionally high specific capacity. However, its widespread use is hindered by a challenging...
Waveguide array transports light without distortion
One of the challenges of optical microscopy is to continually increase the imaging power, or resolution. In the past three hundred odd years, scientists have been building ever-better microscopes. The...
Will there be a second round of coronavirus stimulus checks? Probably not soon
As the economy continues to slide, there is a proposal for a second coronavirus stimulus, but its passage doesn't look likely in the near-term.
A new, highly sensitive chemical sensor uses protein nanowires
Scientists report that they have developed bioelectronic ammonia gas sensors that are among the most sensitive ever made. It uses electric-charge-conducting protein nanowires derived from the bacterium Geobacter to provide...
Atomically thin magnets for next generation spin and quantum electronics
As our smartphones, laptops, and computers get smaller and faster, so do the transistors inside them that control the flow of electricity and store information. But traditional transistors can only...
A new, highly sensitive chemical sensor uses protein nanowires
Writing in the journal NanoResearch, a team at the University of Massachusetts Amherst reports this week that they have developed bioelectronic ammonia gas sensors that are among the most sensitive...
Designing flexible and stretchable single crystal electronic systems
Researchers at the University of Illinois at Urbana-Champaign in collaboration with a Purdue team have discovered that certain crystals are more flexible and stretchable compared to current materials used for...
Aircraft carrier USS Gerald R. Ford fitted to serve 1,000 more personnel
The aircraft carrier USS Gerald R. Ford completed readiness projects to board 1,000 personnel for an upcoming assignment, the Navy said on Wednesday.
Noble metal aerogels enabled by freezing
Chemists developed a freeze-thaw method, capable of synthesizing various noble metal aerogels (NMAs) with clean surfaces and multiscale structure. In virtue of their hierarchical structures and unique optical properties, outstanding...
Tracing the evolution of self-control
Advances in the craftsmanship of stone hand axes around 500,000 years ago suggest individuals at this time possessed characteristics which demonstrate significant self-control, such as concentration and frustration tolerance.
Scarcity reduces consumers' concerns about prices, even during a pandemic, research shows
During the current pandemic, panicked overbuying of products such as toilet paper, cleaning products and similar items often has led to limited options for consumers and empty store shelves. What's...
Speeding up long-range coherent LiDAR
Light detection and ranging (LiDAR) comprises an array of techniques using laser light to measure distances by multiplying the time delay between transmitted and received optical signals with the speed...
'The head-tail of tadpoles': The dynamics of polymers with a very unique shape
They are in the shape of a tadpole and interact with each other by harpooning between head and tail, thus presenting interesting and unexpected physical properties. Tadpoles are the large...
Expandable foam for 3-D printing large objects
It's a frustrating limitation of 3-D printing: Printed objects must be smaller than the machine making them. Huge machines are impractical for printing large parts because they take up too...
Unique polymer-based fabrication process for low-cost, higher yield reprogrammable photonic integrated circuits
The future looks bright for photonic integrated circuits (PICs) as they look destined for use in quantum computing and deep learning technologies. As PICs carry light signals rather than electrical...
Chemistry job seekers face tough outlook during pandemic
