Best thermoelectric efficiency of ever-explored materials

iScience, 2022
Abstract A thermoelectric device is a heat engine that directly converts heat into electricity. Many materials with a high figure of merit ZT have been discovered in anticipation of a high thermoelectric efficiency. However, there has been a lack of investigations on efficiency-based material evaluation, and little is known about the achievable

Exploration of New Electroacupuncture Needle Material [PDF]

Evidence-Based Complementary and Alternative Medicine, 2012
Background. Electro Acupuncture (EA) uses the acupuncture needle as an electrode to apply low-frequency stimulation. For its safe operation, it is essential to prevent any corrosion of the acupuncture needle.Objective. The aim of this study is to find an available material and determine the possibility of producing a standard EA needle that is ...

Recent Progress in Exploring Magnetocaloric Materials [PDF]

Advanced Materials, 2009
AbstractThe magnetic refrigeration technique based on the magnetocaloric effect (MCE) has attracted increasing interest because of its high efficiency and environment friendliness. In this article, our recent progress in exploring effective MCE materials is reviewed with emphasis on the MCE in the LaFe13−xSixbased alloys discovered by us. These alloys

Exploring the High-Pressure Materials Genome [PDF]

Physical Review X, 2018
A thorough in situ characterization of materials at extreme conditions is challenging, and computational tools such as crystal structural search methods in combination with ab initio calculations are widely used to guide experiments by predicting the composition, structure, and properties of high-pressure compounds. However, such techniques are usually
