Tiny light-emitting microalgae, found in the ocean, could hold the secret to the next generation of organic solar cells, according to new research carried out at the Universities of Birmingham and Utrecht.
Matter waves constitute a crucial feature of quantum mechanics, where particles have wave properties in addition to particle characteristics. This wave-particle duality was postulated already in 1924 by the French physicist Louis de Broglie.
On its surface, the work is deceptively simple: Shoot a high-power laser beam onto a piece of metal for a fraction of a second and see what happens. But researchers say the physics of laser welding is surprisingly complex. A better understanding of the interaction between laser and metal could give industry more control over laser welding, a technology that is becoming increasingly popular in manufacturing.
"Many important biological processes occur in three dimensions and on millisecond timescales," says Lars Hufnagel on the rationale for developing the new microscope. Capturing these fast processes is a big challenge in biology. And showing them not only in 2D but in 3D is - next to the needed high resolution - the second main aspect of modern microscopy.
Stretchable electronics, as a kind of "soft" electronic devices which can be stretched, deformed and wrapped onto nonplanar curved surfaces, have attracted tremendous attraction due to their potential applications in wearable electronics, implantable biomedical devices, and artificial electronic skin. So far, many types of stretchable electronic devices have been developed including stretchable transistors, light-emitting diodes (LEDs), supercapacitors, photodetectors, and sensors.
Scientists from the National University of Science and Technology "MISIS" together with their colleagues from Derzhavin Tambov State University and Saratov Chernyshevsky State University have figured out that graphene is capable of purifying water, making it drinkable, without further chlorination. "Capturing" bacterial cells, it forms flakes that can be easily extracted from the water. Graphene separated by ultrasound can be reused.
Irvine, Calif., April 29, 2019 - Drawing design inspiration from the skin of stealthy sea creatures, engineers at the University of California, Irvine have developed a next-generation, adaptive space blanket that gives users the ability to control their temperature. The innovation is detailed in a study published today in Nature Communications.
To meet the demands of an electric future, new battery technologies will be essential. One option is lithium-sulfur batteries, which offer a theoretical energy density more than five times that of lithium-ion batteries. Researchers at Chalmers University of Technology, Sweden, recently unveiled a promising breakthrough for this type of battery, using a catholyte with the help of a graphene sponge.
Researchers have shown that existing optical fiber technology could be used to produce microscopic 3D images of tissue inside the body, paving the way towards 3D optical biopsies.
The use of gene-editing technology to create virus-resistant cassava plants could have serious negative ramifications, according to new research by plant biologists at the University of Alberta, the University of Liege in Belgium, and the Swiss Federal Institute of Technology. Their results show that attempts to genetically engineer the plants to fight off viruses, in fact, resulted in the propagation of mutated viruses in controlled laboratory conditions.
Flinders University archaeologists are using cutting edge subsurface imaging technology to help assist community groups to map unmarked graves and manage their cultural heritage.
A team from Nanyang Technological University, Singapore (NTU Singapore) and the National University Health System (NUHS) has developed a self-inflating weight management capsule that could be used to treat obese patients.
Cognitive impairment associated with cancer, also known as "chemobrain", has gained recognition as a complication of the disease and its treatment, as it can negatively affect the daily lives of cancer patients and survivors.
To a non-physicist, an "atomic beam collimator" may sound like a phaser firing mystical particles. That might not be the worst metaphor to introduce a technology that researchers have now miniaturized, making it more likely to someday land in handheld devices.
The new study is first to show how two types of sand can behave like light and heavy liquids, shedding light on geological processes from mudslides to volcanos and potentially enabling new technologies from pharmaceutical production to carbon capture
