In an international collaboration including EPFL, scientists have achieved giant nonlinearity of UV hybrid light-matter states up to room temperature in a waveguide made of AlInGaN, a wide bandgap semiconductor. The achievement paves the way for new devices in ultrafast chemical and biochemical spectroscopy.

COVID-19 caused a 30% fall in electronic and electrical equipment sales in low- and middle-income countries but only a 5% fall in high-income countries, intensifying the north-south digital divide, the UN says. Sales of heavy appliances like refrigerators fell hardest (6-8%) while laptops, cell phones and gaming equipment defied the general trend, rising in high-income countries and on a global basis, but dropping in low- and middle-income countries.

For example, chemotherapy or radiotherapy, when combined with thermotherapy, kills tumorous cells more effectively. Thermotherapy is considered a promising approach for treating internal lesions, but the advancement in the field depends on the availability of patient-friendly heat-inducing devices capable of rapidly increasing the temperature of target tissues. Current clinical practices a...

While the technology has continued to evolve from lead-acid to lithium-ion, many challenges still exist--like achieving higher density and suppressing dendrite growth. Experts are racing to address the growing, global need for energy-efficient and safe batteries. The electrification of heavy-duty vehicles and aircraft requires bat...

Credit: SUTD Researchers from the Singapore University of Technology and Design (SUTD) have developed novel techniques, known as Automated Fibre Embedding (AFE), to produce complex fibre and silicone composite structures for soft robotics applications. Their work was published in IEEE Robotics and Automation Letters. Many soft robot components, including sensors and actuators, utilise embedded continuous fibres within elastomeric substrates to achieve various functionalities. However, manual e...

Just a few seconds with the tube in the wrong position might lead to a critical lack of oxygen ...

New research shows that when water comes into contact with an electrode surface all its molecules do not respond in the same way. This can dramatically affect how well various substances can dissolve in water subject to an electrical field, which in turn, can determine how a chemical reaction will occur. And chemical reactions are a necessary component in how we make...everything. The implications of this new revelation could have a remarkable impact on all water-related processes from water pu...

Supported by two Office of Naval Research grants totaling $900,000, Wenxin Liu, of Lehigh University, will continue research into the advanced control of power systems through algorithmic design and hardware experimentation. He will examine real-time optimal power flow control in power electronic power distribution systems and investigate the coordination of heterogeneous generators within a naval ships power system. Both projects could lead to improvements in civilian microgrid technology.

Skoltech scientists have studied the hydroxyl defects in LiFePO4, a widely used cathode material in commercial lithium-ion batteries, contributing to the overall understanding of the chemistry of this material. This work will help improve the LiFePO4 manufacturing process to avoid formation of adverse intrinsic structural defects which deteriorate its performance.

The system offers an economical way to source essential battery material.
