Low-Energy Electron Potentiometry: Contactless Imaging of Charge Transport on the Nanoscale

Scientific Reports, 2015
Charge transport measurements form an essential tool in condensed matter physics. The usual approach is to contact a sample by two or four probes, measure the resistance and derive the resistivity, assuming homogeneity within the sample.

Evolution of Thiosemicarbazones: From First‐ to Second‐Generation Metal Chelators and Their Reactive Oxygen Species‐Mediated Effects in Melanoma

ChemistryOpen, Volume 15, Issue 6, June 2026.
Thiosemicarbazones (TSC) have demonstrated promise as new chemotherapeutic agents against melanoma in both in vitro and In vivo studies. TSC are powerful metal coordinating agents, coordinating transition metal ions such as zinc, copper and iron in multiple oxidation states. It is this metal coordination that imparts the anticancer activity.

Effect of Early‐Stage Crystallization on the Mechanical Properties of Transparent Niobium Silicate Glass Ceramics

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
ABSTRACT Although various strengthening strategies are being exploited to address the inherent brittleness of glasses, they often fail in integrating fracture resistance with preserved transparency, making the pursuit of robust yet transparent glass‐based materials a compelling challenge.
