The definition of a battery is a device that generates electricity via reduction-oxidation (redox) reaction and also stores chemical energy (Blanc et al., 2010). This stored energy ...
On compression of alpha-cristobalite SiO2 to pressures above approximately 12 GPa, a new polymorph known as cristobalite X-I forms. The existence of cristobalite X-I has been known for several decades ...
The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...
An enigmatic L-shaped structure found underground near the pyramids at Giza may be an entrance to a mysterious deeper feature below it. When you purchase through links on our site, we may earn an ...
Abstract: This article describes the first-order perturbation analysis of nonlinear responses in surface acoustic wave (SAW) resonators on the LiTaO3/SiO2/Si structure, where bulk wave radiation is ...
ABSTRACT: Silicate glasses and glass ceramics in the system CeO2-PbO-SiO2 have been studied as a function of the structure factors R and K. The latter two factors are defined as: R = (CeO2 + PbO)/SiO2 ...
WASHINGTON, D.C., September 5, 2017 -- Water has many ice phases that form under different pressure and temperature conditions. The effects of positive pressure have been explored extensively, with ...
Relatively little is known about the effects of extreme negative pressure on water molecules. Exploring a significant region of negative pressure through molecular dynamic simulations, researchers ...
ABSTRACT: A series of emulsion paint samples were prepared using Eziulo clay as an extender, commercial whiting, and titanium dioxide (TiO2). The clay that was calcined at 850oC and sieved to three ...
