We report on electron identification methods and their performance in the Belle experiment at the KEK-B asymmetric B-Factory e+e− storage ring. Electrons are selected using a likelihood approach that takes information from the electromagnetic calorimeter, the central drift chamber, and the silica aerogel Cherenkov counters as input. We achieve an electron identification efficiency of (92.4±0.4)...

Even though aerosol injection into stratosphere is one of the most promising solar geoengineering techniques, sulfate aerosols, which are suggested for such an application, show significant drawbacks as infra-red (IR) absorption and ozone degradation. The development new materials application that would exhibit substantial up-scattering, with non-IR to allow a cooling effect needed. Here, novel...

Abstract The mechanical properties of SiO 2 aerogel prepared under atmospheric pressure are poor, so it is difficult to prepare large pieces materials for practical engineering. In this paper, trimethylchlorosilane (TMCS) was used as a surface modifier transform hydrophilic substances with higher activity into hydrophobic groups, improve the network strength aerogel. Super-hydrophobic by sol-ge...
