Transparent β-quartz s.s. glass-ceramics in Li2O–Al2O3–SiO2 system have an undesirable brown color owing to Fe ions as a contaminant, whereas the mother glass normally has a clear appearance. Elucidation of the coloration mechanism during crystallization is important for industry to develop highly transparent materials. In this study, the mother glass contained SiO2, Al2O3, and Li2O as its prin...

Chemical exfoliated ultra-thin MoS2 nanosheets (NSs) with well 2D structure were demonstrated for interfacial layers and Ag nanowires composite transparent electrode in polymer solar cells (PSCs). The smooth and uniform n-type and p-type (after the plasma treatment) MoS2 NSs could improve fill factor of devices and light absorption in active layer. The optimized Ag nanowires-MoS2 NSs (AgNW-MoS2...

The sub-wavelength structures in moth eyes exhibit fascinating antireflective properties over the broadband wavelength region and at large incident angle by generating an air-mixed heterogeneous optical interface. In this work, antireflective behavior of transparent glass is observed with the elaborate controls of the nanopillar morphology. The reflectance spectrum shows a red shift and a notab...

Nematode specimens for taxonomical work generally are mounted permanently in glycerol between two coverslips in a Cobbs aluminum slide or on a glass slide under a thin coverslip. In both cases, glass fibers of suitable diameter are used to keep the coverslip from pressing on the specimens. For larger nematodes, pieces of nickel-chrome wire can be used instead of the glass fibers (1). These type...

A transparent interface reveals some of the inner workings of a system. Transparency is important in computer systems that must engender trust, that teach, or that must rely on users to correct their mistakes. While glass-box transparency provides a view of internal components, generalized transparency encompasses exposing design criteria and assumptions that are often hidden from end users. Cr...

Transparent oxyfluoride glass-ceramic (OxGCs) coatings with composition 1.2Nd3+ 80SiO2- 20LaF3 were prepared following a sol-gel route labelled “pre-crystallized nanoparticles route”. OxGCs are transparent materials composed by one or more fluoride nanocrystals in glass matrix. have been encouraging results powders and bulk glass-ceramics but not coatings. In the present work, aqueous suspensio...
