Metal‐free Hydrogen Generation from Seawater and Silicon Waste: A Circular Approach

Angewandte Chemie, EarlyView.
Hydrogen was rapidly generated directly from untreated seawater and polymeric Si waste without any transition metal catalyst. The in situ generated polymeric cross‐linked Si resin was completely depolymerized under mild conditions into chloro‐silane monomers.

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 ...

Organically Modified Silicates (Ormosils) as Adhesives for Siliceous Surfaces [PDF]

The Journal of Adhesion, 1987
Abstract Adhesion to glass surfaces still may be a problem under “heavy duty” conditions such as temperature and moisture or both. In many cases the problem may be overcome by use of adhesion promoters such as reactive silanes. These silanes remove water films from the glass surface by chemical reaction, are able to form chemical bonds to the glass ...

Integrating Automated Electrochemistry and High‐Throughput Characterization with Machine Learning to Explore Si─Ge─Sn Thin‐Film Lithium Battery Anodes

Advanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
A closed‐loop, data‐driven approach facilitates the exploration of high‐performance Si─Ge─Sn alloys as promising fast‐charging battery anodes. Autonomous electrochemical experimentation using a scanning droplet cell is combined with real‐time optimization to efficiently navigate composition space.

Degradation Pathways of Silicon‐Based Anodes in Lithium‐Ion Batteries

Advanced Energy Materials, EarlyView.
Silicon‐based anodes undergo degradation through five primary pathways: (1) mechanical and structural deterioration of the active material, (2) loss of electrode integrity and electrical contact, (3) mechanical instability of the solid electrolyte interphase (SEI), characterized by repetitive fracture and deformation, (4) chemical instability of the ...

Viscosities of melts in the Na2O---FeO---Fe2O3---SiO2 system and factors controlling relative viscosities of fully polymerized silicate melts [PDF]

, 1988
Na2O---B2O3---SiO2 and Na2O-Ga2O3 viscosities decrease in the order aluminosilicate > ferrosilicate, (galliosilicate ?) > borosilicate. Thp electronegativities of the trivalent cations are inversely correlated with the relative viscosities of melts in ...
