Low-energy dissociative electron attachment to molecular acetonitrile (CHCN) is investigated by recording the efficiency curves of CHCN, CHCN, and CN products, but the present curves are distinctly different from those in the previous reports. Now it is recommended that the reaction thresholds of e + CHCN → H + CHCN and CH + CN are respectively about 1.51 and 1.52 eV, and four shape-resonant states, one Π and three ∑, of CHCN are involved in the fragmentations at the low and high electron-attachment energies. By using a high-resolution anion velocity-map imaging spectrometer, we obtain the CN momentum images at the electron attachment energies of 7.10, 7.60, and 8.10 eV and interpret them with four pathways concerning two- and three-body dissociations.

This report investigates the preparation, characterization, and application of activated carbon derived from Spathodea campanulata flowers (SCAC) to remove Congo Red (CR) dye from aqueous streams. SCAC was synthesized using orthophosphoric acid activation which yielded a mesoporous material with a specific surface area of (986.41 m/g), significantly exceeding values reported for flower-derived activated carbons in the available literature.

The morphology of wheat starch granules with different damaged starch (DS) content was analyzed using a particle size analyzer and scanning electron microscopy (SEM); the granular structure was studied using FT-IR spectroscopy and X-ray diffraction (XRD); and the granule-water interaction was evaluated by thermogravimetric analysis (TGA) and dynamic vapor sorption (DVS). The increase in the level of DS shifted the population of B-type granules towards larger particle diameters and shifted the population of A-type granules towards smaller particle diameters. The appearance of the surface of the starch-damaged granules was rough and flaky (SEM images).

The development of efficient catalysts for water electrolysis is crucial for advancing the low-carbon transition and addressing the energy crisis. This work involves the fabrication of graphene-based catalysts for the oxygen evolution reaction (OER) by integrating NiFe-LDH and PbO onto graphene using plasma treatment. The plasma process takes only 30 min.

Coumarin compounds have heterocyclic core with different properties such as high quantum yields, broad Stokes shifts, and superior photophysical and biological activity. It is known that fluorescence properties increase with increased intramolecular charge transfer in systems where electron-withdrawing or donor groups are attached to different positions of the coumarin compound. When these compounds interact with analytes in the environment, the analytes in the environment can be detected by quenching or increasing fluorescence.
