Exploring the Immobilization Strategies of Lewis Bases on Lignocellulosic Bamboo Shavings and their Applications in Cycloaddition of CO2 and CO2 Derivatives

Advanced Sustainable Systems, Volume 9, Issue 12, December 2025.
Biobased bamboo shavings are used to immobilize Lewis base catalysts for CO2 valorization. Two methods are investigated for immobilization of catalysts: covalent isocyanate coupling and silane condensation. The isocyanate method achieves 100% conversion of cyclic carbonate starting from epoxides, whereas the silane method yields glycerol carbonate with

Strength and thermal stability of enhanced metakaolin‐based geopolymer composites with sand and fibers

International Journal of Applied Ceramic Technology, Volume 22, Issue 6, November/December 2025.
Abstract The growing demand for sustainable materials in construction and ceramics has driven interest in geopolymer technology as an eco‐friendly alternative to traditional cement‐based systems. Geopolymers, synthesized from aluminosilicate precursors like metakaolin, offer high mechanical performance, chemical resistance, and lower carbon footprints.

Spermatophyta Molecular Clock: Time Drift and Recent Acceleration

Plant-Environment Interactions, Volume 6, Issue 5, October 2025.
Exponential increase in the base substitution rate in recent geologic time. ABSTRACT Angiospermae radiation is widely recognized as a mid‐Cretaceous event, but the adaptive radiation of Asarum and Viola as spring ephemerals also occurred during the Quaternary. To better understand the evolution of Angiospermae through geological time, a robust and well‐
