Solid electrolyte particle sizes affect ion pathways

Superconductive materials can conduct electricity with no resistance, but typically only at very low temperatures. Realizing superconductivity at room temperature could enable advanced, energy-efficient electronics and other technologies. Now, an international research team is one step closer to such an achievement.

A collaborative research team from Kanazawa University, the Indian Institute of Technology Hyderabad, and the University of Strathclyde has developed a novel method for forming high-performance high-entropy alloy (HEA) films on various surfaces—without the need for costly alloy targets. By using a proprietary rotating target composed of multiple pure metal segments and pulsed laser deposition (PLD) technology, the team successfully demonstrated a cost-effective and versatile approach to HEA film fabrication.

Groundbreaking cerium oxide-based thermal switches achieve remarkable performance, transforming heat flow control with sustainable and efficient technology.

Researchers in Tokyo find that a 100-year-old method for redirecting water can be used to control heat dissipation in electronics

Solid-state batteries are a safer option that can hold even more energy than current go-to lithium-ion versions, but effectively harnessing their structure-performance relationship has remained a complex barrier to better batteries. Now, however, researchers at Tohoku University’s Advanced Institute for Materials Research in Japan have developed a framework to predict how the structure of solid-state electrolytes can affect the performance of a battery.

Researchers at the Institute of Industrial Science, The University of Tokyo studied the anomalous properties of amorphous solids, including glasses, using computer simulations, and found a common vibrational mechanism underlying them, which may help control the glass properties

Milling rice to separate the grain from the husks, produces about 100 million tons of rice husk waste globally each year. Scientists searching for a scalable method to fabricate quantum dots have developed a way to recycle rice husks to create the first silicon quantum dot LED light. Their new method transforms agricultural waste into state-of-the-art light-emitting diodes in a low-cost, environmentally friendly way.

An international research group demonstrated that the Kondo effect can have a significant impact on transition metal oxide compound, which has unique and desirable properties to realize wide range of quantum phenomena. The findings have provided more evidence in a decade long debate.

In 2019, a new superconductor was discovered amongst the nickelates (nickel-based oxides), but only now have the underlying physical and chemical similarities with their Periodic-Table twin superconductors, the cuprates, been identified.

Giants in History: Chinese physicist Xie Xide (19 March 1921 – 4 March 2000) was an influential educator and one of China’s pioneer researchers of solid-state physics.
