Capillary rise results from a combination of two effects: the tendency of the liquid to wet (bind to) the surface of the tube (measured by the value of the contact angle), and the action of the liquid's surface tension to minimize its surface area. ...
Superionics are fascinating materials displaying both solid- and liquid-like characteristics: as solids, they respond elastically to shear stress; as liquids, they display fast-ion diffusion at normal conditions. In addition to such scientific interest, superionics are technologically relevant for energy...
In this paper, dielectric constants of lossy organic liquids are measured using oscillation frequency shifts of a negative-resistance voltage-controlled os... V Sekar - 《IEEE Transactions on Microwave Theory & Techniques》 被引量: 26发表: 2012年 Dielectric Behavior of the Relaxor Pb(Mg1/3Nb2/...
Solubility of Gases in Liquids. XVI. Henry's Law Coefficients for Nitrogen in Water at 5 to 50°C The solubility of nitrogen in pure liquid water was measured in the pressure range 45 to 115 kPa and in the temperature range 5 to 50°C. These data are us... TR Rettich,R Battino,E...
The densities and viscosities of choline chloride/urea deep eutectic solvents (DESs) at molar ratios of 1:1.5, 1:2, and 1:2.5 (abbreviated as [ChCl][Urea]1.5, [ChCl][Urea]2 and [ChCl][Urea]2.5) were measured in this work. In addition, the effects of ethanol on the density and ...
