The Stable Li-S Battery Battery Structure Is Found

As an enormous potential lithium ion battery, the energy storage of Li-S each unit is five times of the weight. However it owns short life. The good news is Journal <Science Advances> reports: A research team lead by Doctor Mahdokht Shaibani from Monash University Australia already found stable enough new Li-S battery structure, which get prospect in improving battery life of smart phone to five days. By report, the new… Read More »The Stable Li-S Battery Battery Structure Is Found

Bulletproof Foam Metal Make Military Vehicle Lighter and More Efficient

How to use lightest material for bullet proof? This question motivate material scientists to chase breakthrough in advanced light armour, so it could reduce burden of infantry and make military vehicles lighter. Now Researchers from North Carloina State University developed a new bulletproff material, whose property is equal to traditional armour, however the weight is half of the traditional one. The research team announced a impressive research in 2015, which… Read More »Bulletproof Foam Metal Make Military Vehicle Lighter and More Efficient

Rare Earth Oxides

New Rare Earth Separation Method Is Found

In Chinese myth, “Xi Rang” is a kind of soil that never stops growing. Now, A new extractive precipitant that is similar to “Xi Rang” is developed. What the magic is it compounds with rare earths and forms solid extraction complex, which can repeatly extract and recycled. It raise the efficiency of rare earth separation and enrichment, which avoid large wastes from traditional technology. As nonrenewable scarce strategic resources, rare… Read More »New Rare Earth Separation Method Is Found

Lanthanum Hydride LaH10

Superconductor Under Nearly Room Temperature Is Found LaH10

The fuction of superconductor is well known. If this material with 0 resistance could be used widely, it could improve present electronic technique to unprecedented height. Present difficulty is only available at extremely low temperature ( close to absolute temperature). Recently Mikhail Eremets and the colleagues from Max Planck Institute found the superconductivity of lanthanum hydride (LaH10) show at 250K or -23℃. The temperature mean to close to room temperature.… Read More »Superconductor Under Nearly Room Temperature Is Found LaH10

A New Source of Rare Earths Are Found:Phosphate Tailing

Recently researchers from University of New Brunswick did researches and confirmed: Phosphate tailing may be the potential source of rare earth elements. They added that” Assuming the production of neodymium, dysprosium and other rare earth elements are in the potential shortages in America, it would threaten the energy security of America”. Rare earth elements are absolutely necessary parts in solar energy, wind energy, advanced automobile technology, smart phone and other… Read More »A New Source of Rare Earths Are Found:Phosphate Tailing

Superconductivity of Lanthanum Hydride

Superconductivity of Lanthanum Hydride Appear At 7 Centigrade and Extreme Pressure

The earlier of December, 2018, Mikhail Eremets and his colleague from MARPLE Chemical Institute, Germany found the superconducting properties of lanthanum hydride(LaH10) appear at 250K or -2℃, however it needs high pressure condition as 170Gpa,which is equal to half of earth center pressure or 1 million 700 thousand times of standard atmospheric pressure. At the same time, the researchers from George Washington University found lanthanum hydride acts superconductivity at 280K(7℃),… Read More »Superconductivity of Lanthanum Hydride Appear At 7 Centigrade and Extreme Pressure

Scientists Invent New Smelting Technology,Which make copper get similar properties to gold

As one of the most sought-after material, the metal owns a series of excellent features, its application is wide for various industries. However as for a noble metal, the cost of its raw material is relatively expensive. Is there a method that can make material with more abundant reserves( for example copper that owns similiar properties? The good news is the goal have achieved to a certain extent, although Chinese… Read More »Scientists Invent New Smelting Technology,Which make copper get similar properties to gold

Boron Arsenide

Boron Arsenide Can Provide Good Heat Dissipation For High Power Electronic Products

The inside of high power electronic devices should be kept with cooling when working. It will slow program run if  the inner temperature is much high, even freeze or may shut down. The researchers from UIUC and UTD cooperated and optimized crystal growth of boron arsenide, which make it own excellent thermal performance. It can efficiently dissipate heat from electronic devices. The research was published on <Science>, which mean preconceived… Read More »Boron Arsenide Can Provide Good Heat Dissipation For High Power Electronic Products
