Room-temperature bonded interface improves cooling of gallium nitride devices
A room-temperature bonding technique for integrating wide bandgap materials such as gallium nitride (GaN) with thermally-conducting materials such as diamond could boost the cooling effect on GaN devices and facilitate...
High color purity UV organic emission realized using asymmetric microcavity design
Ultraviolet organic light-emitting devices (UVOLEDs) are expected to develop into compact, environmentally friendly and large-size ultraviolet light source applications in analysis, information storage, display, biomedical, etc. However, most of the...
Heavy metal ion detection and extraction using paper-based atom stamp printed devices
Microfluidic paper-based analytical devices (µPADs) are a promising concept with rapid development in recent years. In a new study published on Nature: Microsystems & Nanoengineering, a team led by Yanfang Guan and Baichuan...
An all-electric magnetic logic gate
A team of researchers from ETH Zurich and the Paul Scherrer Institute has developed a way to build an all-electric magnetic logic gate. In their paper published in the journal...
Researchers create focus-free camera with new flat lens
Using a single lens that is about one-thousandth of an inch thick, researchers have created a camera that does not require focusing. The technology offers considerable benefits over traditional cameras...
Gold nanoparticles uncover amyloid fibrils
EPFL scientists have developed powerful tools to unmask the diversity of amyloid fibrils, which are associated with Alzheimer's disease and other neurodegenerative disorders. The scientists made the breakthrough by developing...
New universal carrier ink for 3-D printing
Researchers at ETH have produced a gel from cellulose fibers and biodegradable nanoparticles that liquefies when pressed through the nozzle of a 3-D printer, but then quickly returns to its...
How impermeable is the impermeable graphene?
New experiments by researchers at The University of Manchester have placed the best limits yet on impermeability of graphene and other two-dimensional materials to gases and liquids. The work has...
Physicists use extreme infrared laser pulses to reveal frozen electron waves in magnetite
Magnetite is the oldest magnetic material known to humans, yet researchers are still mystified by certain aspects of its properties.
Heat and light create new biocompatible microparticles
Biomedical engineers at Duke University have devised a method for making small particles that are safe for living tissues that will allow them to create new shapes attractive for drug...
Spring reading: 10 books being adapted for film, TV
"Little Fires Everywhere," "David Copperfield," "The Woman in the Window," "Artemis Fowl" and other books are being adapted for film and television.
'Spillway' for electrons could keep lithium metal batteries from catching fire
Nanoengineers at the University of California San Diego developed a safety feature that prevents lithium metal batteries from rapidly heating up and catching fire in case of an internal short...
Warriors fans prepare for 'bizarre' home game with empty arena
Golden State is set to become the first NBA team to play a game without fans in the arena, leading to what one fan calls a "bizarre" situation.

Understanding how monomer sequence affects conductance in 'molecular wires'
Researchers in the Schroeder and Moore groups at the University of Illinois at Urbana-Champaign have published a new study that illustrates how changes in the polymer sequence affect charge transport...
Overclassification may cloud, confuse need for Space Force, Air Force secretary says
Secretary of the Air Force Barbara Barrett said this week that better transparency may be the key to overcoming skepticism about the newly created Space Force.
Magic twist angles of graphene sheets identified
Graphene is 200 times stronger than steel and can be as much as 6 times lighter. These characteristics alone make it a popular material in manufacturing. Researchers have now identified...
Dancing electrons solve a longstanding puzzle in the oldest magnetic material
Magnetite is the oldest magnetic material known to humans, yet researchers are still mystified by certain aspects of its properties. For example, when the temperature is lowered below 125 kelvins, magnetite changes from...
