Chemists at the School of Science of the Hong Kong University of Science and Technology (HKUST) have recently made ...
Results of numerical simulation of a miniaturized sub-THz traveling-wave tube amplifier with sheet electron beam and planar grating slow wave structure (SWS) are presented. Cold characteristics of the ...
Teaching the VSEPR (valence shell electron-pair repulsion) model can be a tedious process. Traditionally, Lewis structures are drawn and the number of “electron clouds” (groups) around the central ...
In a size regime where every atom counts, rational design and synthesis of optimal nanostructures demands direct interrogation of the effects of structural divergence of individuals on the ...
Credit: Nature Communications (2025). DOI: 10.1038/s41467-025-56888-6 The structure showed 12 transmembrane helices in two pseudo-symmetric bundles and two periplasmic subdomains.
The impact of high energy electrons in multi-layered shielding structures has been measured in terms of dose enhancement effects. New dosimetric data from a series of extensive experimental tests have ...
