NiAl, owing to its affordability and straightforward disposal, presents a promising avenue for U(VI) decontamination, a process potentially leveraging surface complexation and photocatalytic reduction. Utilizing stereoselective living coordinative copolymerization, 1-alkenes and 4-aryl-16-heptadienes can be combined, with or without a reversible chain transfer agent in excess, to create a highly flexible method of producing multivariate, hyperdimensional, functionalized semi-crystalline or amorphous polyolefins. These polymers can incorporate either mono- or difunctionalized end-groups, alongside a programmable level of orthogonal functional group incorporation within the main chain. A one-step bis-allylation process allows for the facile production of non-conjugated diene comonomers from a wide assortment of aryl carboxaldehyde starting materials. These findings pave the way for exploring a vast new realm of functional polyolefin applications, accessible in substantial and scalable quantities. For the development of high-performance X-ray detectors, the crucial components are scintillators with rapid decay times, high light yield, outstanding stability, and substantial X-ray absorption, all of which are hard to achieve in a single material structure. LaCsSiS4 1%Ce3+, a lanthanide chalcogenide, is presented as the first example simultaneously embodying multiple key attributes for an ideal scintillator application. The LaCsSiS4 scintillator, activated with 1% Ce3+, displays an exceptionally low detection limit of 4313 nanograms per square centimeter per second and a high photoluminescence quantum yield of 9824%, contributing to a substantial light yield of 504801441 photons per MeV. Subsequently, this material showcases unwavering resistance to radiation and moisture, making it fit for chemical processing under solution conditions. For the purpose of demonstrating the X-ray imaging capabilities of LaCsSiS4 1%Ce3+, a flexible X-ray detector was produced, resulting in a high spatial resolution of 82 lines per millimeter. This study emphasizes lanthanide chalcogenides' potential for high-performance scintillation applications. We present a detailed account of the one-pot aminoalkylation of styrene derivatives, using boronic acids (BAs) and boronic acid pinacol esters as radical precursors, resulting in complex secondary amines in moderate to high yields through a mild and readily accessible organophotoredox-catalytic four-component reaction. In addition, this photoredox process, for the first time, demonstrates the activation of alkyl boronic acid derivatives by imines, which function as both the substrate and a Lewis base activator. The protocol's successful adaptation to photoflow reactors yielded a considerable enhancement in its applicability. Lithium-sulfur (Li-S) batteries are considered to be a promising energy storage solution with high energy density. Nevertheless, the cycling performance of lithium-sulfur batteries is hampered by the undesirable reactions between lithium metal anodes and soluble lithium polysulfides. Although LiPS electrolyte encapsulation (EPSE) efficiently prevents parasitic reactions, it unfortunately compromises the sulfur redox kinetics of the cathode. A redox co-mediation approach for EPSE is proposed to overcome the preceding dilemma and realize Li-S batteries with both high energy density and long cycling endurance. Li-S batteries incorporating EPSE technology effectively utilize dimethyl diselenide (DMDSe) as a superior redox co-mediator to expedite sulfur redox reactions. DMDSe, present in EPSE, accelerates the conversion kinetics of LiPS in both liquid-liquid and liquid-solid transformations, and retains the capacity to minimize anode parasitic reactions initiated by LiPSs. Following this, a Li-S pouch cell with an energy density of 359 Wh/kg at the cell level, showing significant stability over 37 cycles, was realized. This study demonstrates an e
