Electrical engineers from Duke University have developed the first electromagnetic metamaterial in the world without any metal. The ability of the device to absorb electromagnetic energy without heating up has direct applications in sensing, imaging, and lighting.
A team of researchers and engineers at Caltech and ETH Zurich have created an artificial skin with the ability to detect temperature changes using a mechanism similar to the one used by the organ that enables pit vipers to sense their prey.
Among materials, there is a familiar anomaly, a nonconforming metal, the properties of which have been discovered through a new study carried out by an international research team including scientists from the Department of Energy’s (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Berkeley.
Chemical separation processes make up nearly 15% of the total global energy consumption. Among the drivers for more efficient, mass separation processes that could greatly decrease that number is the development of advanced molecularly-selective synthetic membranes.
When a material is created, you cannot change whether that material is soft or hard. However, a group of scientists at University of Michigan have developed a new method to design a "metamaterial" that can switch between being soft and hard without altering or damaging the material.
As drugs that comprise of one or more fluorine atoms tend to be more powerful, highly stable, and easily absorbed by the body, drug developers would like to incorporate fluorine or trifluoromethyl, a fluorine-comprising unit, into experimental drugs. However, this process has been challenging.
Researchers from King Abdullah University of Science and Technology (KAUST) have demonstrated that a greener and simpler version of the C-H activation reaction can be carried out using light from a standard electric light bulb. According to the research team, this is one of the most innovative new reactions for the assembly of complicated chemical structures.
A new chemical reaction that is catalyzed using simple iron salts - an abundant, low-cost, and sustainable substitute for highly expensive and scarce metals - has been developed by researchers from the University of Huddersfield.
In order to characterize a category of metals with fascinating electronic properties that can help to discover other, similarly endowed materials, researchers from Princeton, Yale, and the University of Zurich have put forward a theory-based approach.
Researchers have now discovered the reason behind improvement in battery performance when charged metal atoms are added to tunnel structures within the batteries, which could help in developing faster recharging lithium batteries.
