The earth's environmental problems, especially for water remediation, need effective methods to solve. Materials with special wettability are developed for the separation of oil/water mixtures. However, the separation of emulsified oil/water mixtures can be a real challenge. There is still much deficiencies, on account of the surfactant, which could link water molecules and oil molecules to for...

We report efficient electrolysis of both water-splitting half reactions in the same medium by a bifunctional 3D electrode comprising Co3O4 nanospheres nucleated on the surface of nitrogen-doped carbon nanotubes (NCNTs) that in turn are grown on conductive carbon paper (CP). The resulting electrode exhibits high stability and large electrochemical activity for both oxygen and hydrogen evolution ...

Heteroatomic substitution and vacancy engineering of spinel oxides can theoretically optimize the oxygen evolution reaction (OER) through charge redistribution d-band center modification but still remain a great challenge in both preparation catalytic mechanism. Herein, we proposed novel efficient Ar-plasma (P)-assisted strategy to construct heteroatom Mo-substituted vacancies enriched hierarch...

Graphene (Gr)/metal oxide nanocomposites, as advanced electrode materials, have drawn significant attention in supercapacitors due to their two components' synergistic cooperation, which compensates each other's drawbacks and hence perform better than individual components. In this study, graphene/metal Gr/NiO Gr/Co3O4 binaries were separately synthesized by a co-precipitation method NiO or Co3...

The responses of isolated thoracic aortic rings to 10(-5) M norepinephrine (NE) and 5 mM lanthanum chloride (La3+) were compared in tissues from 6- to 8-week-old and 12- to 16-week-old rats. Twelve strains of rats were selected: spontaneously hypertensive (SHR), Wistar-Kyoto (WKY), genetically related outcross F1 and F2, backcross BC1(S) and BC1(W), and Wistar, SHR/Wistar, and Wistar/WKY crosse...

ATP-dependent Ca2+ uptake, ATPase phosphorylation, and Pi production by sarcoplasmic reticulum vesicles were measured in rapid quench experiments, using trichloroacetic acid, H&+, EGTA, EDTA, and La3+ as quench reagents. Trichloroacetic acid, EDTA, and H&+ cause total inhibition of enzyme activity and loss of accumulated calcium. On the other hand, EGTA and La3+ permit retention of calcium accu...

In this report, a novel hierarchical peapoded array with Co3O4 nanoparticles encapsulated in graphitized carbon fiber is introduced for the first time. The unique peapoded structure is suitable for the excellent anode in LIBs and demonstrates enhanced rate capability, cyclability and prolonged lifespan, e.g. the specific capacity can reach up to 1150 mAh/g. All the enhanced electrochemical perf...

A new electrochemical dual amplification sandwich immunosensor (DASI) was designed for ultrasensitive and accurate detection of the breast cancer susceptibility gene based on the combination of N-doped graphene, hydroxypropyl chitosan and Co3O4 mesoporous nanosheets. N-doped graphene has better electroconductibility than traditional graphene. It is an ideal electrochemical material with a large...

Biofuel cells (BFCs), which use enzymes as catalysts to harvest energy from green and sustainable fuels abundantly producible from biological systems, are promising next-generation energy devices. However, the poor stability and high specificity to only one fuel type of these bio-catalysts largely limits the practical use of current BFCs. In this contribution, we demonstrate a unique fuel cell ...

cobalt oxide (co3o4) nanorods were prepared by a simple co-precipitation method using ethanol solution of cobalt nitrate as precursor and cetyl trimethylammonium bromide (ctab) as surfactant. morphological properties of the nanoparticles were characterized. xrd measurement exhibited the structure of co3o4 nanocrystals for annealed samples. the sem images revealed that the particles changed from...
