Ultrathin (submicrometer) organic films of specified index of refraction are constructed by the sequential deposition of self-assembled zirconium phosphonate (ZP) molecular monolayers that contain two Merent bisphosphonate ions, 1,lO-decanediylbis(phosphonate) (DBP) and 4,4azobis[(p-phenylene)methylenelbis(phosphonate) (AZO). By varying the ratio of DBP to AZO monolayers in the ZP multilayer fi...

The present review describes the current achievements in applications of a planar laser-induced fluorescence (PLIF) method for diagnostics liquid films, bubbles, individual droplets, and sprays. Such flows are related with strongly curved interphases, which often results additional high errors during PLIF data quantification because laser light reflection, refraction, absorption. demonstrates t...

In irregular astigmatism, the two meridians may be located at something other than 90 degrees apart (principal meridians are not perpendicular); or there are more than two meridians. Irregular astigmatism is that in which the curvature varies in different parts of the same meridian or in which refraction in successive meridians differs irregularly. Irregular astigmatism is associated with loss ...

Abstract Solar thermal power generation integrates photothermal conversion and low-cost, large-scale heat storage, which is the primary support for constructing a green system with new energy as main body. The concentrating critical component of solar plants. However, traditional concentrators are bulky require complex tracking systems, limiting reduction costs. metasurface can freely regulate ...
