Meta-Aerogel Ion Motor for Nanofluid Osmotic Energy Harvesting Adv. Mater. (IF 32.086) Pub Date : 2023-06-09 Feng Zhang, Jianyong Yu, Yang Si, Bin Ding
Osmotic power, also known as “blue energy”, is a vast, sustainable and clean energy source that can be directly converted into electricity by nanofluidic membranes. However, the key technological bottleneck for large-scale osmotic electricity is that macroscopic-scale bulky membranes cannot synergistically satisfy the demands of high power density and low resistance without sacrificing scalability

Interlayer coupling in materials, such as exchange interactions at the interface between an antiferromagnet and a ferromagnet, can produce exotic phenomena not present in the parent materials. While such interfacial coupling in magnetic systems has been widely studied, there is considerably less work on analogous electric counterparts (i.e., akin to electric “exchange-bias-like” or “exchange-spring-like”

Imine-based covalent organic frameworks (COFs) are crystalline porous materials with prospective uses in various devices. However, general bulk synthetic methods usually produce COFs as powders that are insoluble in most of the common organic solvents, arising challenges for the subsequent molding and fixing of these materials on substrates. Here, we report a novel synthetic methodology that utilizes

Cu-exchanged mordenite (MOR) is a promising material for partial CH4 oxidation. The structural diversity of Cu species within MOR makes it difficult to identify the active Cu sites and to determine their redox and kinetic properties. In this study, the Cu speciation in Cu-MOR materials with different Cu loadings has been determined using operando electron paramagnetic resonance (EPR) and operando ultraviolet-visible

Since polyoxometalates (POMs) can undergo reversible multi-electron redox transformations, they have been used to modulate the electronic environment of metal nanoparticles for catalysis. Besides, POMs possess unique electronic structures and acid-responsive self-assembly ability. These properties inspire us to tackle the drawbacks of the well-known copper-catalyzed azide-alkyne cycloaddition (CuAAC)

We demonstrate that arylchlorodiazirines serve as photo-activated halocarbene precursors for the selective one-carbon ring expansion of N-substituted pyrroles and indoles to the corresponding pyridinium and quinolinium salts. Preliminary investigations indicate that the same strategy also enables the conversion of N-substituted pyrazoles to pyrimidinium salts. The N-substituent of the substrate plays

Photocatalytic 2-Iodoethanol Coupling to Produce 1,4-Butanediol Mediated by TiO2 and a Catalytic Nickel Complex Angew. Chem. Int. Ed. (IF 16.823) Pub Date : 2023-06-09 Qingchun Xu, Puning Ren, Yang Peng, Nengchao Luo, Zhuyan Gao, Caixia Meng, Jian Zhang, Feng Wang
Photocatalytic 2-iodoethanol (IEO) coupling provides 1,4-butanediol (BDO) of particular interest to produce degradable polyesters. However, the reduction potential of IEO is too negative (−1.9 vs NHE) to be satisfied by most of the semiconductors, and the kinetics of transferring one electron for IEO coupling is slow. Here we design a Ni-complex cocatalyst, which works synergistically with TiO2, realizing
