Utilization of 29Si MAS-NMR to Understand Solid State Diffusion in Energy Storage Materials

open access: yesFrontiers in Chemical Engineering, 2022
The properties of many solid-state materials arise from critical interfaces tied to the structure, morphology, and composition of the materials under study.

Additive Effects of Dietary Supplementation with Zeolite and Methyl-Sulfonyl-Methane on Growth Performance and Interleukin Levels of Broiler Chickens

open access: yesThe Journal of Poultry Science, 2023
Silicate minerals are common additives in poultry feed. To assess their effects, we added zeolite (ZEO) and methyl-sulfonyl-methane (MSM) to broiler chicken diets.

Silicates, Silicate Weathering, and Microbial Ecology [PDF]

open access: yesGeomicrobiology Journal, 2001
Mineralogy, microbial ecology, and mineral weathering in the subsurface are an intimately linked biogeochemical system. Although bacteria have been implicated indirectly in the accelerated weathering of minerals, it is not clear if this interaction is simply the coincidental result of microbial metabolism, or if it represents a specific strategy ...

The influence of the annealing mode on stress elimination in a foam glass structure [PDF]

open access: yesJournal of the Serbian Chemical Society, 2021
The purpose of this work was to establish the influence of features of the annealing mode on the value of residual stresses in the structure of porous inorganic materials using foam glass as an example.

Review and perspective of high-k dielectrics on silicon

open access: yesJournal of Telecommunications and Information Technology, 2023
The paper reviews recent work in the area of high-k dielectrics for application as the gate oxide in advanced MOSFETs. Following a review of relevant dielectric physics, we discuss challenges and issues relating to characterization of the dielectrics ...

Sticking Properties of Silicates in Planetesimal Formation Revisited [PDF]

open access: yesAstrophysical Journal, 2019
In the past, laboratory experiments and theoretical calculations showed a mismatch in the derived sticking properties of silicates in the context of planetesimal formation. It has been proposed by Kimura et al.

The layer silicate Cs2SnIVSi6O15

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2022
Single crystals of Cs2SnSi6O15, dicaesium tin(IV) hexasilicate, were serendipitously obtained from a CsCl/NaCl flux at 923 K, starting from mixtures of CaO, SnO and TeO2 in a closed silica ampoule. The crystal structure of Cs2SnSi6O15 is constructed from

Amorphous silicates in the matrix of Semarkona: The first evidence for the localized preservation of pristine matrix materials in the most unequilibrated ordinary chondrites

open access: yesMeteoritics and Planetary Science, 2020
We have investigated the fine‐grained matrix of the least‐altered unequilibrated ordinary chondrite (UOC) Semarkona (LL3.00) using different electron microscope techniques. Unlike previous studies, which found that the matrix of Semarkona was extensively
