AbstractAryl thianthrenium salts are valuable in photocatalysis but traditionally require external electron donors for activation. This study introduces an energy transfer (EnT) strategy for the activation of aryl thianthrenium salts using 2,3,4,5,6-penta(carbazol-9-yl)benzonitrile (5CzBN) as a metal-free photocatalyst, eliminating the need for external donors.

AbstractThe catalytic conversion of ortho-hydrogen (o-H2) to para-hydrogen (p-H2) serves as a crucial step in the storage of liquid hydrogen. A variety of iron-cobalt bimetallic catalysts (FCO) were synthesized using a precipitation method, incorporating diverse levels of Co doping into Fe-based catalysts. The effects of Co doping on the crystal structure, porosity, and magnetism of FCO catalysts were studied by XRD, N2 physical adsorption, FTIR, XPS, and VSM analyses.

1. IntroductionTo decrease the use of fossil fuels and CO2 emissions, the past decade has seen a rapid increase in the deployment of renewable distributed generation (DG). This growth, however, introduces difficulties for managing active distribution networks (ADN). On one hand, the mismatch between DG distribution and demand can cause reverse power flow and worsen voltage issues, potentially leading to the simultaneous need for DG curtailment and load shedding within a system.

In this paper, we show that a periodically driven Aubry-André-Harper model with imbalanced on-site gain/loss supports universal one-way transport that is immune to impurities and independent of initial excitations. We reveal the underlying mechanism that the periodic driving gives rise to the non-Hermitian skin effect in the effective Floquet Hamiltonian, thereby causing universal nonreciprocal transport.

1. IntroductionViruses, which are omnipresent infectious agents, can infect a diverse array of organisms globally. Recent epidemics, such as those caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) [1], Zika virus (ZIKV) [2], and Ebola virus (EBOV) [3], have inflicted substantial socioeconomic damage.

Abstract:As a large number of flexible elements such as distributed power and flexible load are connected to microgrids, the economic improvement of microgrids has become an important topic through rational energy distribution. In this paper, an economic scheduling model considering the load demand for a microgrid system under the mechanism of a peak–valley tariff is proposed.
