Silicate dielectric ceramics for millimetre wave applications [PDF]
Journal of the European Ceramic Society, Volume 41, Issue 7, July
2021, Pages 3879-3894, 2021 Silicate ceramics are of considerable promise as high frequency dielectrics in emerging millimetre wave applications including high bandwidth wireless communication and sensing. In this review, we show how high quality factors and low, thermally stable permittivities arise in ordered silicate structures.

Activated crystalline silicon dioxide mitigates weight loss in lactating sows
Italian Journal of Animal Science, 2022 This study investigated activated crystalline silicon dioxide (SIL) supplementation in late pregnancy and lactating sows on reproductive parameters as well as the performance of suckling piglets. Eighty sows were assigned to two groups: control (CON, n =

Enhanced silicate weathering is not limited by silicic acid saturation [PDF]
Proceedings of the National Academy of Sciences, 2011 Enhanced weathering of olivine as a means of sequestering carbon is investigated by Kohler et al. (1). Specifically, the study discusses the potential distribution of fine olivine powder, obtained from dunite mines, in the humid tropic regions of the Amazon and Congo River catchments. Olivine (forsterite) dissolution (Eq.
