Defect engineering in photocatalysts represents a fundamental method toward tailoring their solar-to-chemical energy conversion performance, although determining the nature and impact of subsurface defects remains challenging. Single-unit-cell Bi2WO6 monolayers, forming sandwich-like structure, [BiO]+–[WO4]2––[BiO]+, exhibit promising photocatalytic performance are an ideal system for isolating defects. We report single-step synthesis monolayers rich stable interior W vacancies characterize...

Proton exchange membrane fuel cell (PEMFC) is one of the most promising green power sources, in which perfluorinated sulfonic acid ionomer-based membranes (e.g., Nafion) are widely used. However, widespread application PEMFCs greatly limited by sharp degradation electrochemical properties proton under high temperature and low humidity conditions. In this work, high-performance sulfonated carbon nanotubes/Nafion composite (Su-CNTs/Nafion) for were prepared mechanism microstructures on...

High durability of low-k value is a desired property for dielectrics serving under humid conditions, because absorbing small amount moisture by the material can considerably increase k so as to result in function deterioration. Aiming develop dielectric polymer with superior and high thermal stability, perfluorocyclobutyl (PFCB) biphenyl ether-based polyimide, PFCBBPPI, was synthesized. This possesses Tg 310.3 °C 5% weight loss temperature 510.5 °C. PFCBBBPPI exhibited an extremely low water...

The incorporation of oxygen vacancy defects into the catalysts has been attracting significant interest for regulating performance photocatalysts. Single-atomic-site metal have also paid ever-growing attention because they maximized atom efficiency and thus generated excellent catalytic performance. Herein, we report interaction decorated atomically dispersed Pt to boost efficient photocatalytic process. Compared with TiO2 without defects, under same theoretical amount support, all...

Complement receptor 1–related gene/protein y (Crry) is a potent murine membrane complement regulator that inhibits classical and alternative pathway C3 convertases. In nephrotoxic serum (NTS) nephritis, injected antibodies (Abs) bind to glomeruli, leading activation subsequent glomerular injury albuminuria. To study the phenotypic effects of continuous blockade, transgenic mice were created express recombinant soluble (rs) Crry directed by broadly active heavy metal-inducible...

In a strategy to specifically target complement inhibitors sites of activation and disease, recombinant fusion proteins consisting inhibitor linked C3 binding region receptor (CR) 2 were prepared characterized. Natural ligands for CR2 are breakdown products deposited at activation. Fusion human fragment either the N terminus or C soluble forms membrane decay accelerating factor (DAF) CD59. The targeted bound C3-opsonized cells, all significantly more effective (up 20-fold) than corresponding...
