On the constitution of silicate groupings in binary lead silicate glasses [PDF]

Journal of Non-Crystalline Solids, 1976
Abstract Direct chemical methods have been used to determine the type and the percentage of silicate groupings present in binary lead silicate glasses within the composition range 4PbO · SiO2PbO · SiO2. The results obtained indicate that the constitution and the relative amounts of various silicate groupings change with the changing total amount of ...

3D Concrete Printing of Triply Periodic Minimum Surfaces for Enhanced Carbon Capture and Storage

Advanced Functional Materials, EarlyView.
A 3D‐printable and carbon‐capturing concrete is developed by replacing cement with diatomaceous earth (DE), which enhances rheology, provides hierarchical porosity, and serves as a nucleation site for carbonation. Maximum absorption of 488.7 gCO2 kgcement−1 is achieved in 7 days, a 142% increase over conventional concrete, and the triply periodic ...

On Ultrasmall Silicate Grains in the Diffuse Interstellar Medium [PDF]

, 2000
The abundance of both amorphous and crystalline silicates in very small grains is limited by the fact that the 10 micron silicate emission feature is not detected in the diffuse ISM. On the basis of the observed IR emission spectrum for the diffuse ISM, the observed ultraviolet extinction curve, and the 10 micron silicate absorption profile, we obtain ...

Crystal structures of Ca4+xY3–xSi7O15+xN5–x(0 ≤ x ≤ 1) comprising of an isolated [Si7(O,N)19] unit

Acta Crystallographica Section E: Crystallographic Communications, 2019
Single crystals of the solid solution series Ca4+xY3–xSi7O15+xN5–x were obtained by a solid-state reaction method using a flux for x = 0, 0.5 and 1, resulting in Ca4Y3Si7O15N5 (tetracalcium triyttrium heptasilicon oxynitride), Ca4.5Y2.5Si7O15.5N4.5 and ...

Untangling the Role of Capping Agents in Manipulating Electrochemical Behaviors Toward Practical Aqueous Zinc‐Ion Batteries

Advanced Materials, EarlyView.
Inspired by the critical role of capping agents in nanomaterials synthesis and bulk crystal growth, the role of capping agents in manipulating the electrochemical behaviors of AZIBs is untangled. The multifunctional role of the capping agents in terms of the Zn anode, electrolyte, and cathode validates stable and practical AZIBs. Abstract Long‐standing

Investigation of Magnesium Silicate as an Effective Gate Dielectric for AlGaN/GaN Metal Oxide High Electron Mobility Transistors (MOSHEMT) [PDF]

arXiv, 2023
In this study, a 6 nm layer of Magnesium Silicate (Mg-Silicate) was deposited on AlGaN/GaN heterostructure by sputtering of multiple stacks of MgO and SiO$_{2}$, followed by rapid thermal annealing in a nitrogen (N$_{2}$) environment. The X-ray photoelectron spectroscopy (XPS) analysis confirmed the stoichiometric Mg-Silicate (MgSiO$_{3}$) after being ...
