Investigation of the Effect of Processing and Sintering Parameters on Voltage-Dependent Variable Resistors for Controlling Voltage and Leakage Current in ZnO-Based Compositions

مواد نوین
Introduction: Voltage-dependent resistors, known as varistors, have wide applications in the electrical and electronic industries due to their protective role against the destructive effects of sudden voltage spikes. This research investigates the impact

Effect of primer composition on zirconia surface properties and bond strength

European Journal of Oral Sciences, Volume 134, Issue 1, February 2026.
Abstract This study investigated the effects of different surface treatments on surface roughness, wettability, and shear bond strength of 3Y‐TZP (yttria‐stabilized tetragonal zirconia polycrystal). A total of 180 specimens (6 × 6 × 2 mm) underwent sandblasting with 50 µm Al2O3 and were divided into six groups: (i) control (no treatment), (ii) 10‐MDP +

Influence of Rare Earth Elements on Prebiotic Reaction Networks Resembling the Biologically Relevant Krebs Cycle

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
Rare earth elements can act as mediators in a prebiotic reaction network, producing various intermediates of the citric acid cycle starting from glyoxylate and pyruvate. The ionic radius and the resulting variation in Lewis acidity has a significant influence on the observed product scope.

Tuning the microstructural and micro‐/nanomechanical properties of silicon nitride–carbon nanotube composites by powder oxidation

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Microstructure showing hexagonal α‐Si3N4 (green arrows) and CNTs distributed between beta‐Si3N4 (yellow arrows) and the oxidation impact to elastic moduli. Abstract The effects of the oxidation on the micro/nanohardness, density, and microstructure of the silicon nitride–carbon nanotube (Si3N4–CNT) composite were investigated.
