Advances in modern electronics has demanded the requisite hardware, transistors, to be smaller in each new iteration. Recent progress in nanotechnology has reduced the size of silicon transistors down to the order of 10 nanometers. However, for such small transistors, other physical effects set in, which limit their functionality. For example, the power consumption and heat production in these devices is creating significant problems for device design. Therefore, novel quantum materials and device concepts are required to develop a new generation of energy-saving information technology. The recent discoveries of topological materials -- a new class of relativistic quantum materials -- hold great promise for use in energy saving electronics.Researchers in the Louisiana Consortium for Neutro...

NASA scientists have definitively detected the chemical acrylonitrile in the atmosphere of Saturn's moon Titan, a place that has long intrigued scientists investigating the chemical precursors of life. On Earth, acrylonitrile, also known as vinyl cyanide, is useful in the manufacture of plastics. Under the harsh conditions of Saturn's largest moon, this...Powered by WPeMatico

CVD Diamond Coating: New innovative process improves the adhesion of diamond to cemented carbide

To reduce process costs in industrial parts manufacturing while simultaneously improving quality, the use of diamond-coated, cemented carbide cutting tools has increased. Adhesion of diamond coatings was previously problematic, particularly when processing composite or lightweight materials. Suitable pretreatment is therefore vital. Dr. Manuel Mee of the Fraunhofer Institute for Mechanics of Materials IWM has developed a new pretreatment routine that increases the adhesion of CVD diamond to carbide: by combining several approaches into a single process, all factors which affect the adhesion of the coating can be taken into consideration, leading to a fundamental improvement of the adhesion.Today cemented carbide is the most commonly used material for industrial cutting tools. This is thank...

Oestrogen regulates pathological changes of bones via bone lining cells

The female sex hormone oestrogen protects the structural stability of bones. To date, however, it had been unclear exactly which cells were involved in the hormone’s protective function in preventing changes in bone density. Researchers at Vetmeduni Vienna were able to show for the first time that oestrogen uses a certain cell type as a “mediator” for its beneficial effects on bone. When oestrogen binds to these so-called “bone lining cells”, which cover the bone surfaces, it regulates the expression of a protein called RANKL in these cells. Oestrogen deficiency leads to uncontrolled expression of RANKL, which can trigger pathological changes in the bones. Published in Scientific Reports.The most important female sex hormone, oestrogen, plays a crucial role in the regulation of bone mass.
