Linker‐Engineered Dimeric Acceptors Afford Efficient Organic Photocatalytic Hydrogen Evolution via Tailored Nanomorphology for Long‐Lived Charge Accumulation

Advanced Materials, EarlyView.
We developed a new series of monomeric (MY) and dimeric acceptors incorporating unfused (DY1) and fused (DY2) linkers, which establish a controlled self‐aggregation trend of MY > DY2 > DY1. The DY2‐based system yields a bulk‐heterojunction nanoparticle morphology that appears to balance phase separation and interfacial accessibility, consistent with ...

Steric Coordination Modulated Iodine Chemistry With Four‐Electron Conversion for Zinc‐Iodine Batteries

Advanced Materials, EarlyView.
A dual‐additive electrolyte strategy is developed to address the hydrolysis of I+ in the aqueous electrolytes. The steric‐hindrance effect of TES− effectively shields I+ from nucleophilic attacks by hydroxyl groups, facilitating the reversible I−/I0/I+ conversion with four‐electron transfer.

UV‐vis spectroscopy of gas‐phase ions

Mass Spectrometry Reviews, 2021
AbstractPhotodissociation action spectroscopy has made a great progress in expanding investigations of gas‐phase ion structures. This review deals with aspects of gas‐phase ion electronic excitations that result in wavelength‐dependent dissociation and light emission via fluorescence, chiefly covering the ultraviolet and visible regions of the spectrum.

UV-Vis Spectroscopy

2013
In a UV-Vis (ultraviolet-visible light) spectroscopic measurement, light absorption as a function of wavelength provides information about electronic transitions occurring in the material. For semiconductors, UV-Vis spectroscopy offers a convenient method of estimating the optical band gap, since it probes electronic transitions between the valence ...

UV/VIS‐spectroscopy of liquid slags

Steel Research, 1999
UV/VIS‐spectroscopical methods have been applied to investigate the absorption behaviour of CaO‐Al2O3‐SiO2‐slags in a wide temperature range from 20 to 1655°C. The observations reveal a strong temperature dependence of the absorption bands, which can be explained by means of a newly developed theoretical model.
