A research team has developed a hierarchical-shell perovskite nanocrystal technology that simultaneously overcomes the ...

Dalaroo increases global focus on Greenland with strong critical minerals results from its maiden sampling program at Blue ...

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 ...

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 ...
