Combining Thermogravimetry-Mass Spectrometry and Target Factor Analysis for Rapid Characterization of Volatiles from Degradation of Epoxy Paint.

Thermogravimetry coupled with simultaneous evolved gas analysis by mass spectrometry was used for discerning organic compounds released during the thermal degradation of paint whose chemical compositions are not readily accessible. Thermogravimetric analyses up to 600°C revealed distinct degradation patterns under inert and oxidative conditions. Significant degradation of paint initiates at around 360°C and concludes at 500°C in a nitrogen atmosphere.

Current challenges in dental education- a scoping review.

Introduction: This scoping review aimed to review the various challenges facing dental education. Dental education faces multiple institutional, student and faculty-based challenges. Institutional challenges include updating infrastructure resources, recruiting qualified faculty, and implementing administrative policies that enhance dental education.

EARTH-ABUNDANT 3d-TRANSITION METAL METASILICATES AS EFFECTIVE ELECTROCATALYSTS FOR ALKALINE HER: CuZnSiO3 OUTPERFORMS CuSiO3 AND ZnSiO3.

Hydrogen evolution reaction (HER) is a key reaction in electrochemical water splitting for hydrogen production leading to the development of potentially sustainable energy technology. Importantly, the catalysts required for HER must be earth-abundant for their large-scale deployment; silicates representing one such class. Herein, we have synthesized a series of transition mono- and bi- metal metasilicates (with SO32- group) using facile wet-chemical method followed by calcination at a higher temperature.
