Biological Activity of Alkali Treated Aureomycin
Experimental Biology and Medicine, 1951 SummaryAlkali treated Streptomyces aureojaciens fermentation liquor contained considerable unchanged aureomycin. The pure antibiotic is inactivated by similar treatment. The product arising from mild alkaline inactivation of aureomycin was isolated and found to have essentially no antibacterial activity and no growth stimulating activity for the chick.

Advanced Functional Materials, EarlyView.Dual‐cation site engineering unlocks stable and fast sodium storage in Na4VMn(PO4)3 cathodes. Li+ at Na2 suppresses Jahn‐Teller distortion, while K+ at Na1 expands ion channels, enabling synchronized V/Mn redox and quasi‐single‐phase kinetics. This atomic‐level strategy achieves ultralong cycling stability, high‐rate capability, and full cell viability

Alkaline Activation of Kaolin Group Minerals
Crystals, 2020 Zeolites can be obtained in the process of the alkali-activation of aluminosilicate precursors. Such zeolite–geopolymer hybrid bulk materials merge the advantageous properties of both zeolites and geopolymers. In the present study, the effect of the type

Binder Chemistry – Low-Calcium Alkali-Activated Materials [PDF]
, 2013 Early developments in the developments of low-calcium (including calcium-free) alkali-activated binders were led by the work of Davidovits in France, as noted in Chap. 2. These materials were initially envisaged as a fire-resistant replacement for organic polymeric materials, with identification of potential applications as a possible binder for ...

Lithium Intercalation in the Anisotropic Van Der Waals Semiconductor CrSBr
Advanced Functional Materials, EarlyView.We report the lithium intercalation in the layered van der Waals crystal CrSBr, revealing strongly anisotropic ion‐migration dynamics. Optical and electrical characterization of exfoliated CrSBr shows lithium diffusion coefficients that differ by more than an order of magnitude along a‐ and b‐directions, consistent with molecular dynamics simulations ...

Production of Green Cement from Slag Enhanced by Egyptian Metakaolin Materials
Journal of Building Materials and Structures, 2020 New geopolymer-based materials offer excellent perspectives for the future; they should not be regarded as competitive materials for Portland cement, which has been the reference construction material for so long, but as alternative materials with a ...
