The paper describes and compares the performance of two options for numerically representing the surface tension force in combination with the level set interface-tracking method. In both models, the surface tension is represented as a body force, concentr ...
A method for separating and recovering silicon debris from sawing waste is characterized in that it comprises the following steps: - treating the sawing waste so as to deoxidize the silicon debris in a manner that reduces their surface energy, - applying t ...
Magnetic impurities in solids cause manifold changes in their macroscopic properties, such as anomalous low temperature resistance due to Kondo screening, reduction of the superconducting transition temperature due to local suppression of the order paramet ...
Natural surfaces are often structured with nanometre-scale domains, yet a framework providing a quantitative understanding of how nanostructure affects interfacial energy, gamma(SL), is lacking. Conventional continuum thermodynamics treats gamma(SL) solely ...
Liquid supramolecular nanostamping (LiSuNS) is an efficient stamping technique that replicates various DNA features with no need of solid surface contact. LiSuNS is based on the specific interaction of complementary DNA strands. An original pattern compose ...
The structures of the liquid surface of sodium have been characterized with extensive first-principles molecular dynamics simulations based on ensemble density functional theory. Friedel oscillations in the electronic charge density at the free surface wer ...
Isothermal NaCl sintering experiments are conducted between 500 and 790 degrees C on powders 75, 100, 150 and 400 mu m in average diameter. Along with literature data, the results are compared with theoretical predictions for the initial stage of sintering ...
The dynamic of a cavitation bubble inside a water drop is investigated in microgravity in order to analyze the interaction between the collapsing bubble and a quasispherical free surface. Tests are carried in the frame of the 42nd parabolic flight campaign ...
The cavitation phenomenon, which is due to a pressure drop in liquid flows, may be responsible of noise and vibration as well as efficiency alteration and material erosion. A tremendous work has been already performed to better understand the onset and dev ...
