Experimental methods in chemical engineering: Atomic absorption spectrometry—AAS

The Canadian Journal of Chemical Engineering, Volume 104, Issue 5, Page 2206-2224, May 2026.
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 ...

Dual‐Molten‐Salt Etching Strategy Enables Built‐in Electric Field in Mo‐MXene/NiFeSe Heterostructure for Superior OER Performance

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 3, May 2026.
A dual‐molten‐salt etching strategy was employed to construct a built‐in electric field in the Mo‐MXene/NiFeSe heterostructure to achieve excellent oxygen evolution reaction. Transition metal selenides have emerged as potential catalysts for the oxygen evolution reaction, yet their practical implementation faces two fundamental challenges: irreversible

Extraction, Structural Characterization and Anti‐Inflammatory Activity of Polysaccharides From Conioselinum vaginatum

Food Science &Nutrition, Volume 14, Issue 5, May 2026.
This study employed an ultrasonic‐assisted extraction (UAE) method combined with column chromatography purification to obtain two homogeneous polysaccharides (CVP‐I and CVP‐II) from Conioselinum vaginatum, which exhibited distinct physicochemical properties and structural characteristics, and exerted anti‐inflammatory effects by inhibiting the ...

RNA Modifications: Current Understandings and Future Perspectives

MedComm, Volume 7, Issue 5, May 2026.
Types of RNA modification. We have summarized the currently common types of RNA modifications, including ac4C, m6A, m1A, m5C, m3C, m7G, and ψ, and visually characterized their features through structural formulas. The characteristic structures are marked with a background color different from the background color.

Dimensionality Engineering of 1D, 2D, and 3D High‐Entropy Alloys for Advanced Electrocatalysis

Small Structures, Volume 7, Issue 5, May 2026.
This review summarizes recent advances in the synthesis and electrocatalytic applications of high‐entropy alloys (HEAs) in 1D, 2D, and 3D forms. We highlight the unique structural advantages and superior performance of dimensionally engineered HEA in key electrocatalytic reactions, including water splitting, hydrogen oxidation, alcohol oxidation, CO2 ...

The Relationship Between Catalyst and Solvent in Hydrogenation via Condensed Phase Heterogeneous Catalysis

ChemSusChem, Volume 19, Issue 8, 28 April 2026.
Heterogeneous catalysis has historically been developed in the gas phase, however, we have found it pertinent to highlight solvent effects that must be accounted for in liquid environments. Condensed phase catalysis, like that in biomass, petroleum and the conversion of CO2, stands to benefit from the typically overlooked discussion regarding the ...
