Giant electric-field-induced strain in lead-free piezoelectric materials
First-principles calculations are performed to investigate the structures, electrical, and magnetic properties of compressive BiFeO3 films under electric-field and pressure perpendicular to the films. A reversible electric-field-induced strain up 10% is achieved in the compressive BiFeO3 films. The giant strain originates from rhombohedral-tetragonal (R-T) phase transition under electric-filed,...
متن کامل特集 Lead - Free Brush Materials for Starter Motors *
This paper reports the development of a lead-free brush material for high-load starter motors. These brushes can be used in much more extreme conditions --at a PV-value (the product of the brush contact pressure and sliding velocity) approximately three times that of conventional starter motor brushes, and double the electrical current density. The major technical requirement for this developme...
متن کاملPlatelets take the lead in lymphatic separation.
The circulatory system of mammals consists of 2 components, blood vessels and lymphatic vessels, which are counterparts that act in parallel but develop in series. Unlike blood vessels that are a system built up to form a closed circuit carrying circulating blood, lymphatic vessels differ in that it is an open system with unique architecture starting at its periphery as a blunt end specialized ...
متن کاملGermany and China take the lead.
he foundation of the 2015 Paris climate agreement was to a large extent based on cooperation between the United States and China on clean energy and emissions reductions. With the United States now planning to withdraw from the agreement, who will replace them? Ahead of the United Nations climate conference in Bonn that begins next week, the spotlight is on Germany to fill the vacancy. Indeed, ...
متن کاملHow successful plants take the lead
Germinating quickly, growing fast, withstanding competitors and defending against herbivores already since decades, ecologists have suggested that these are important characteristics of successful plants. However, it has also been suggested that species characteristics are less important as determinants of plant establishment success than other factors such as seed availability or environmental...
