Broadband Conductance Matching Effect in Conductive Metamirrors

Advanced Physics Research, EarlyView.
A conductance matching effect is revealed in conductive metamirrors whose input conductance can be broadband self‐matched to the free space when the conductivity‐thickness product equals 8 mS. This effect enables thickness‐invariant perfect absorption at low frequencies, and tunable resonances at higher‐order modes, providing new opportunities for ...

Recessed Microelectrodes as a Platform to Investigate the Intrinsic Redox Process of Prussian Blue Analogs for Energy Storage Application

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
A microelectrochemical analytical tool is proposed for the accelerated evaluation of the intrinsic electrochemical performance of Prussian‐blue analogues as solid active materials in Na+‐based batteries. By confining the solid active material inside a recessed microelectrode, accelerated voltammetric and galvanostatic cycling at high C‐rate become ...

Structural Aspects of Lithium‐Ion Conduction in the Phosphidotitanate Li8TiP4 and Its Comparison With Li7+5xTa1−xP4 and Li8−xTi1−xTaxP4

Chemistry – A European Journal, EarlyView.
ABSTRACT The chemical system Li/Ti/P has previously been subject to intensive investigation. However, reliable structural data for the reported phases have remained elusive. Motivated by the growing interest in phosphorus‐based lithium‐ion conductors, we have reinvestigated the synthesis, crystal structure, and physical properties of Li8TiP4.

Accessing Sn≥2 States of a TADF Emitter by Femtosecond NIR Spectroscopy

Chemistry – A European Journal, EarlyView.
The depicted thermally activated delayed fluorescence (TADF) emitter was studied by femtosecond near‐infrared (NIR) spectroscopy. A prominent NIR transition was shown to be strongly solvent‐dependent, with implication for intersystem crossing in the compound.

Experimental methods in chemical engineering: Atomic absorption spectrometry—AAS

The 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 ...

Iron and Nickel Substituted Perovskite Cobaltites for Sustainable Oxygen Evolving Anodes in Alkaline Environment

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Perovskite oxide catalysts with reduced Co content, substituted by Fe and Ni, are synthesized and studied for their activity in the oxygen evolution reaction in alkaline media. An increase in the intrinsic catalytic activity (obtained by the (RctCdl)−1 product) of the base material (Ba0.5Gd0.8La0.7Co2O6‐δ) is seen for an as high as 70 % substitution of

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

ChemSusChem, 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.
