Electrons inside solid materials can only take certain values of energy. The allowed energy ranges are called "bands," and the space between them, the forbidden energies, is known as "band gaps." Both of them together constitute ...
The need for sustainable and environment-friendly solutions has accelerated the global demand for green and renewable technologies. In this regard, semiconductor photocatalysts have emerged as an attractive solution, owing ...
Photoelectrochemical processes have been considered sustainable alternatives for the remediation of water contaminated by domestic or industrial effluents. Simply put, the strategy consists of using solar energy to degrade ...
The fierce competition between China and the United States of America for control of emerging technologies such as AI and 5G will determine the international balance of power, a new study says.
Gas sensors have been widely applied in areas such as medical health, environmental monitoring, and food safety. However, current gas sensors still face several challenges, including low sensitivity, long response and recovery ...
It has been known for centuries that light exhibits wave-like behavior in certain situations. Some materials are able to rotate the polarization, i.e. the direction of oscillation, of the light wave when the light passes ...
Scientists have created conducting two-dimensional polymers exhibiting electron mobility comparable to graphene. Their research has been featured in the online edition of Chem.
EPFL researchers have developed the first comprehensive model of the quantum-mechanical effects behind photoluminescence in thin gold films; a discovery that could drive the development of solar fuels and batteries.
Making ever smaller and more powerful chips requires new ultrathin materials: 2D materials that are only 1 atom thick, or even just a couple of atoms. Think about graphene or ultra-thin silicon membrane for instance.
Researchers from Germany and Singapore have studied a non-equilibrium state of Fermi liquids called the Floquet Fermi liquid (FFL), which is formed when Fermi liquids are subjected to a periodic driving force and kept in ...
