Viscosity Measurement Techniques for High‐Temperature Oxide Glass‐Forming Systems

open access: yesInternational Journal of Ceramic Engineering &Science, Volume 8, Issue 1, January 2026.
ABSTRACT Viscosity is a fundamental physical property that governs the flow and processing behavior of glass‐forming liquids. During glass manufacturing processes, it is thus important to know how rheological properties are influenced by variables such as temperature, chemical composition, and the presence of any inclusions within the melt.

Evaluating composted sewage sludge as a phosphorus fertilizer in wheat grown on soils with different properties

open access: yesJournal of Environmental Quality, Volume 55, Issue 1, January/February 2026.
Abstract Urbanization generates significant amounts of sewage sludge (SS), with relatively high concentrations of plant nutrients such as phosphorus (P). When biochemically stabilized by composting, SS (composted sewage sludge [CSW]) can serve as a sustainable P source in agriculture, supporting a circular economy and reducing agriculture's dependence ...
