General description

Sodium terllurite is an alkali tellurite that is majorly used in the formation of glasses due to its unique properties which include good transmittance, refractive index, and high chemical resistance. It can be used as a tellurite source for the preparation of quantum dots.

In simple oxide glasses the coordination number and oxidation state of the glass-forming element can be predicted directly from the "8--n" rule. Tellurite glasses, however, are unusual in that the coordination number of oxygen around tellurium varies without a corresponding

A hierarchical structure is a prerequisite for a liquid super-repellent surface due to its capability to catch large numbers of fine air-pockets. In the present work, a series of hierarchical nanocomposites with anti-wettability were fabricated by in situ deposition of

Two-dimensional (2D) materials, particularly black phosphorus (bP), have demonstrated themselves to be excellent candidates for high-performance infrared photodetectors and transistors. However, high-quality bP can be obtained only via mechanical exfoliation from high-temperature- and high-pressure-grown bulk crystals and degrades rapidly when
