Chemists produce new oxidants as a tool for preparative chemistry
Chemical oxidation, the selective removal of electrons from a substrate, represents one of the most important transformations in chemistry. However, most common oxidants often show disadvantages such as undesired side...
College football: Arizona State's Turk retains eligibility despite agent, NFL Combine work
The NCAA has restored collegiate eligibility for Arizona State football player Michael Turk, despite the fact the Sun Devils punter declared for the NFL Draft, participated in the Scouting Combine...
Large-scale preparation of polymer-based room-temperature phosphorescence via click chemistry
Polymer-based room-temperature phosphorescence (RTP) materials can be efficiently developed by covalently embedding phosphors into the polymer matrix. The process is still, however, highly challenging on a large-scale due to inefficient...
Observing topological edge states using moiré patterns
NUS physicists have found a new way to create and tune the topological edge states in two-dimensional (2-D) topological insulators (TIs) for potential spintronic device applications.
Levitated timepiece sets new benchmark
A new mechanical "clock" has been created by an international team of researchers, led by scientists at the University of St Andrews, which could test the fundamental physics of gravity.
The sensitive strain sensor that can detect the weight of a feather
Physicists have created the most sensitive strain sensor ever made, capable of detecting a feather's touch.
Etching the road to a hydrogen economy using plasma jets
Hydrogen is a clean energy source that can be produced by splitting water molecules with light. However, it is currently impossible to achieve this on a large scale. In a...
Active particles with light-switchable propulsion direction and reversible interactions
Researchers from the Faculty of Physics at the University of Warsaw, ETH in Zurich and the University of Cambridge have synthesized and analysed active microparticles self-propelling in a fluid and...
Single molecules captured on video at an unprecedented 1,600 frames per second
A team including researchers from the Department of Chemistry at the University of Tokyo has successfully captured video of single molecules in motion at 1,600 frames per second. This is...
VENUS construction on track for ORNL's newest neutron imaging instrument
Researchers and engineers at the Spallation Neutron Source (SNS) are making progress on the construction of VENUS, the facility's newest instrument for studying materials in exciting new ways that are...
JCESR lays foundation for safer, longer-lasting batteries
Electricity storage in batteries is in ever increasing demand for smartphones, laptops, cars and the power grid. Solid-state batteries are among the most promising next-generation technologies because they offer a...
Metasurface opens world of polarization
Polarization, the direction in which light vibrates, is invisible to the human eye. Yet, so much of our optical world relies on the control and manipulation of this hidden quality...
Metasurface opens world of polarization
Researchers have designed a metasurface that can be continuously tuned from linear to elliptical birefringence, opening up the entire space of polarization control with just one device. This single metasurface...
Smart molecules could be key to computers with 100-times bigger memories
Researchers have discovered a single molecule 'switch' that can act like a transistor and offers the potential to store binary information -- such as the 1s and 0s used in...
The leaky pipeline for Black chemists
Many Black students leave chemistry after undergraduate education
Car, illicit barbecue found hidden under camouflage material
A British police department said the smell of cooking breakfast tipped them off to a barbecue and an entire car hidden under camouflage material.
Super water-repellent materials are now durable enough for the real world
Superhydrophobic materials have long promised surfaces that never needed cleaning, or medical equipment that no microbe could ever possibly stick to -- but have always been let down by the...
Double-sided solar panels that follow the sun prove most cost effective
Solar power systems with double-sided (bifacial) solar panels -- which collect sunlight from two sides instead of one -- and single-axis tracking technology that tilts the panels so they can...
Metasurface design methods can make LED light act more like lasers
Researchers continue to push the boundaries of LED design a little further with a new method that could pave the way toward more efficient and versatile LED display and lighting...
