The simultaneous generation of an electron beam with high energy and high current density with a high-fill factor is challenging for a backward wave oscillator (BWO) and other linear-beam devices. To ...

Scientists have discovered a revolutionary new method for creating quantum states by twisting materials at the M-point, revealing exotic phenomena previously out of reach. This new direction ...

When Br dopant was added in addition to Cu, the codoped ZnS NCs showed much stronger PL emission (∼5 × ) compared to the undoped or Cu-doped sample. In conjunction with time-resolved PL results, this ...

Chemists at the School of Science of the Hong Kong University of Science and Technology (HKUST) have recently made ...

It is reduced in the presence of an antioxidant molecule, the absorption decreases and the resulting decoloration is stoichiometrically related to the number of electron captured. Recent studies ...

Dielectric and electrical properties were studied by impedance spectroscopy in air. Impedance spectra were acquired at 25 °C and from 300 to 600 °C under open circuit conditions using a Hewlett ...

In this work, electron paramagnetic resonance (EPR) spectroscopy and X-ray crystallography were used to examine the origins of EPR line shapes from spin-labels at the protein–lipid interface on the ...
