Hereon study shows that microplastics can serve as a transport vehicle for metals in the environment
microplastics metal Organic pollutant
2021/8/10
The fact that microplastics can accumulate organic pollutants from the environment and transport them has been known for some time. What is new, however, is that metals can also be transported in this...
New technology will allow important metals to be made more efficiently
metallic oxide thin film electronic components
2021/8/9
Researchers have invented a cheaper, safer, and simpler technology that will allow a 'stubborn' group of metals, such as the Pt-group elements, to be transformed into thin films for various practical ...
Flexible, wearable X-ray detector doesn’t require heavy metals
X ray imaging MOF Medical imaging
2021/8/6
X-ray imaging is a fast and painless way for doctors to see inside a person. But radiation detectors, which go under the body part being imaged, are rigid panels that contain harmful heavy metals, suc...
New approach improves ability to predict metals’ reactions with water

2017/7/21
The wide reach of corrosion, a multitrillion-dollar global problem, may someday be narrowed considerably thanks to a new, better approach to predict how metals react with water.Researchers at Oregon S...
Potassium Salt Outperforms Precious Metals As a Catalyst
Potassium Salt Precious Metals a Catalyst
2015/3/4
"We have shown for the first time that you can efficiently make carbon–silicon bonds with a safe and inexpensive catalyst based on potassium rather than ultrarare precious metals like platinum, pallad...
Uphill Transport of Rare-Earth Metals through a Highly Stable Supported Liquid Membrane Based on an Ionic Liquid
Uphill Transport Rare-Earth Metals Ionic Liquid
2010/9/17
We have developed a highly stable supported liquid membrane based on ionic liquids (ILs) for the separation of rare-earth metals, employing N,N-dioctyldiglycol amic acid as a mobile carrier. The quant...
