Maxima ( r 1 and r 2 ) of the experimental radial distribution function RDF and the bond angles θ were determined and correlated with TGA (thermogravimetric analysis), DTA (differential thermal analysis) and MS (mass spectrometry). The results indicate that the topological short-range structure ...
A sample of the high‐temperature (β) phase of Nb5Si3, possessing the tetragonal W5Si3structure, had a superconducting transition temperatureT0of 0.7 K an... JO Willis,RM Waterstrat - 《Journal of Applied Physics》 被引量: 57发表: 1979年 Growth mechanism of phases by interdiffusion and di...
atomic structure affects the directional dependence of friction references Friction between two objects can be understood by the making, stretching, and breaking of thousands of atomic-scale asperities. We have probed single atoms... AJ Weymouth,D Meuer,P Mutombo,... 被引量: 0发表: 2017年 Chain...
The atomic structure is often compared to a miniature solar system. 我们时常把电荷的流动比喻为水的流动。 We often compare the flow of electrical charges to the flow of water. 2. (Draws analogy) compare one thing to another: The atomic structure often analogies is miniature solar system. The...
Human noroviruses (HuNoVs) cause sporadic and epidemic viral gastroenteritis worldwide. The GII.4 variants are responsible for most HuNoV infections, and GII.4 virus-like particles (VLPs) are being used in vaccine development. The atomic structure of the
Exposing water to a (2 x 2)-O precovered Pt(111) surface at 100 K and subsequently annealing at 155 K led to the formation of a well-ordered (square root 3 x square root 3)R30 degrees overlayer. The structure of this overlayer is determi... AP Seitsonen,Y Zhu,K Bedürftig,......
Atomic Structure refers to the fundamental components of matter, namely atoms, which consist of a nucleus and orbiting electrons. The nucleus, acting as the center of an atom, is positively charged and has a much greater mass than the negatively charged electrons. Atoms are electrically neutral ...
The precise atomic structure of activated carbon is unknown, despite its huge commercial importance in the purification of air and water. Diffraction methods have been extensively applied to the study of microporous carbons, but cannot provide an unequivocal identification of their structure. Here we ...
The ion-mediated binding seems to provide a possible molecular-level explanation for the low permeability of PG-containing bacterial membranes to organic solvents: highly polar interactions at the water/membrane interface are able to create a high free energy barrier for hydrophobic molecules such as ...
The pursuit of atomic precision structure of porous covalent organic frameworks (COFs) is the key to understanding the relationship between structures and properties, and further developing new materials with superior performance. Yet, a challenge of how to determine their atomic structures has always ...
