- A study highlights a Zr(iv)-carboxylate framework that maintains its crystalline structure even after extreme heat causes its carboxylate links to break.
- When exposed to high temperatures (450 °C and above), the framework undergoes a transformation that generates stable nanographene structures through the benzannulation of alkyne groups.
- The resulting Zr oxide/nanographene hybrid exhibits strong stability, is resistant to harsh chemicals like saturated NaOH and concentrated HPO, and can be modified to increase surface area while keeping its structure intact.
Soil washing is a rapid and efficient remediation technique for soil contaminated by heavy metals. In this study, Cd, Pb, and Zn were removed from contaminated soil by ethylenediamine tetra (methylene phosphonic acid) (EDTMP) and polyacrylic acid (PAA). We then investigated the effect of varying the concentration, pH and duration of the washing processes.

A new Schiff base of N-salicylidene-3-amino-1,2,4-triazole (SAT) was synthesized and its photoluminescent, photochromic and thermochromic properties were characterized and demonstrated. The fluorescence lifetime and quantum yield of SAT were measured and the microcrack bone imaging using SAT as a fluorescent label was observed by laser scanning confocal microscope (LSCM). The absorption spectrum of SAT was demonstrated using DFT/TD-DFT calculation.
