Physical and chemical characterization of recycled glass sand for environmental restoration

Restoration Ecology, EarlyView.
Abstract Introduction We rely on coastal resources for food, water, and energy. However, over 75% of U.S. coastlines are eroding. Concurrently, the U.S. recycles less glass than other developed countries, landfilling hundreds of millions of tons every year.

A Robust Cost‐Effective Spectrophotometric Method for Nb Determination in Refractory Nb‐doped Gadolinium Zirconate: Overcoming Matrix Dissolution Challenges

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT A simple, robust and cost‐effective analytical methodology was developed for the determination of niobium in highly refractory materials: Nb‐doped gadolinium zirconate (Gd2Zr2O7:Nb) and niobium pentoxide (Nb2O5). The challenge of digesting these matrices was successfully accomplished by establishing two independent dissolution procedures: (i ...
