Similarly, polar and dispersive components of the liquid can be measured indirectly with the help of a solid with a well-known surface free energy and its components [33,34]. With the help of the contact angle created by the coating emulsion on the solid product surface, and surface tension...
The liquid cell was made from two vacuum-tight electron transparent membranes with a controlled separation of about 100 nm to 1 µm. Thin SiN films were used as membranes. The cell was filled with the oil. The electron beam was passed through the membranes and oil to allow recording of ...
According to the thickness of liquid film, lubrication regime could be divided into three categAocriceosr:dbinoguntodtahrey tlhuibckrinceastisoonf (liBqLu)i,dmfiilxme,dlulubbrirciactaitoinonre(gMimLe) aconudldhybderdoidvyidneadminictoluthbrreiceactiaoteng(oHriLes).: bOobuvnidouarsylyl,ub...
The indentation depth should be no more than 1/7 of the coating thickness to eliminate and reduce the substrate effect. The liquid-solid contact angle tester (JC2000D, POWEREACH, Shanghai, China) was used to characterize the surface wettability of the coatings. The corrosion experiments were ...

CdSe/CdS dot in rods, rod in rods, and CdSe nanoplatelets have been shown to demonstrate polarized emission for use in a liquid crystal display, acting as optical funnels, absorbing across a significant range of unpolarised wavelengths and then emitting strongly linearly polarised emission at a ...
The wettability of the coatings was determined by the static sessile drop method using DI water as the working fluid. Contact angle (CA) measurement is often used to estimate the wettability of solid surfaces in contact with a liquid. The surface static CAs of the coating surfaces were ...
Additionally, h-BN is an environmentally-friendly material [13], which is being studied as a nanoadditive for liquid lubricants [14–22] because, compared with solid lubricants, liquid lubricant additives present advantages such as faster entrance and replenishment of the sliding interface, and ...
Single, pure Ibp microparticles precipitated as liquid phase microdroplets that then gradually dissolved into the surrounding PBS medium. Analyzing the dissolution profiles of Ibp over time, a diffusion coefficient of 5.5 ± 0.2 × 10−6 cm2/s was obtained by using the EP model, which was in...
On the other hand, other liquid moulding processes, such as resin transfer moulding (RTM), give rise to controlled properties and geometries of the composite parts but require high investments for the equipment and moulds [4]. Compression moulding is also a suitable process for these parts. ...
