Photophysical and Antimicrobial Study of N,N'-Bis(salicylidene)ethylenediamine Schiff Base Metal Complexes (M = Zn(II), Ni(II), Co(II), Cr(II), Fe(III), V(IV), Cu(II), Pd(II))

This study synthesizes and characterizes a series of N,N'-Bis(salicylidene)ethylenediamine Schiff base metal complexes with various transition metals, revealing that metal coordination enhances crystallinity and photoluminescence (notably for Ni and Zn) while significantly improving antimicrobial activity, with Pd and Cu complexes showing the strongest antibacterial and antifungal effects, respectively.

The Role of Chromia Volatilization During Oxidation of Ni-based Alloys in Static Laboratory Air Containing Ambient Humidity

This study demonstrates that even in static laboratory air without intentional water vapor, ambient humidity causes significant chromia volatilization in Ni-based alloy 725, a phenomenon that follows a modified paralinear model with weak temperature dependence and is often overlooked in oxidation research.
