SYNTHESIS OF SPHERICAL SILICA PARTICLES WITH 3-MERCAPTOPROPYL GROUPS IN THEIR SURFACE LAYER [PDF]

open access: yesChemistry Journal of Moldova: General, Industrial and Ecological Chemistry, 2012
Spherical silica particles were synthesized by modified Stöber method using tetraethoxysilane and 3- mercaptopropyltrimethoxysilane (MPTMS). It was shown that their size (500-760 nm) depends on the nature of the catalyst used in the prehydrolysis of ...

Novel Lab‐Scale System for Lyocell Fiber Manufacturing

open access: yesJournal of Polymer Science, Volume 63, Issue 16, Page 3358-3378, 15 August 2025.
ABSTRACT Lyocell man‐made cellulosic fibers (L‐MMCFs) are typically produced from wood sources, but sustainability efforts are driving interest in agricultural biomass feedstocks. This study presents a lab‐scale system for evaluating feedstock viability and processing conditions using a rotary evaporator, syringe pump, and microreactor vessel.
