Structural and Biological Insights Into Copper(I) Phosphane Complexes With Boron‐Phenylated Poly(3‐(CF3)Pyrazolyl)‐ and Poly(6‐(CF3)‐2‐pyridyl)‐Borates

open access: yesChemistry – A European Journal, EarlyView.
This study reports six new copper(I) complexes with unusual coordination and strong anticancer activity against a panel of human cancer cell lines derived from different solid tumors. The most active compounds outperform cisplatin, even in resistant cells, by inhibiting protein disulfide isomerase and inducing redox stress that triggers non‐apoptotic ...

Experimental methods in chemical engineering: Atomic absorption spectrometry—AAS

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Elements absorb electromagnetic radiation (light) of a specific wavelength in proportion to the number of atoms in its path. As the atoms absorb this light energy, electrons rise from the ground state to an excited state. In atomic absorption spectrometry (AAS), high temperatures produce clouds of atoms from the sample (atomization) and ...

Aqueous Supercapacitor with Wide‐Temperature Operability and over 100,000 Cycles Enabled by Water‐in‐Salt Electrolyte

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
This study presents a symmetric supercapacitor with activated carbon electrodes and a “water‐in‐salt” electrolyte (WiSE) based on lithium perchlorate, offering over 100,000 cycles with over 90 % capacity retention. The supercapacitor operates efficiently from −20 to 80 °C, enhancing performance, stability, and all‐season operability.
