Enhancing the efficiency of non-noble electrocatalysts in hydrogen evolution reaction (HER) and oxygen (OER) for water splitting remains a challenging task. Herein, we report an electronic push/pull effect Co Fe doping on HER OER performance Ni-based hydroxides as revealed by thorough cyclic voltammetry X-ray photoelectron spectroscopy analysis. A dopant pulls partial electrons from nearby Ni/Co active sites resulting higher electron affinity at to facilitate OH– adsorption charge transfer...
Co3O4-δ quantum dots (Co3O4-δ-QDs) with a crystallite size of approximately 2 nm and oxygen vacancies were fabricated through multicycle lithiation/delithiation mesoporous Co3O4 nanosheets. Used as an evolution reaction (OER) electrocatalyst for water splitting, the catalytic performance (an overpotential 270 mV@10 mA cm-2 no decay within 30 h) Co3O4-δ-QDs is superior to that previously reported Co-based catalysts state-of-the-art IrO2. Compared nanosheets, enhanced OER activity attributed...
Oxygen evolution reaction (OER), as the critical step in splitting water, is a thermodynamically "up-hill" process and requires highly efficient catalysts to run. Arrhenius' law suggests that higher temperature, faster rate, so larger OER current density can be achieved at lower η. Herein, we report an abnormal temperature effect on performance of Co-based catalysts, e.g., Co3O4, Li2CoSiO4, Fe-doped Co(OH)x, alkaline electrolytes. The reached maximum when increased 65 °C, declined became...
A novel structure enables Li–S batteries to display large-capacity, high-rate and long-life at an ultra-high areal sulfur loading.
2D amorphous iron phosphate nanosheet coated carbon exhibits high rate capability and ultra-long cycle life for sodium ion batteries.
Annual variations of egg production rate (EPR) and clutch size Calanus sinicus, as well body females (prosome length dry weight), were investigated at a series stations in the Southern Yellow Sea by onboard incubation. sinicus was spawning all 11 cruises investigated, annual variation EPR bimodal. Monthly average highest from May to July, respectively, 5.97, 5.36 6.30 eggs female−1 d−1, then decreased dramatically only 1.37 d−1 August attained lowest 1.07 October. In November, increased...
Lung-targeting sophoridine-loaded poly(lactide-co-glycolide) (PLGA) microspheres were constructed by a simple oil-in-oil emulsion-solvent evaporation method. The obtained systematically studied on their morphology, size distribution, drug loading, encapsulation efficiency, in vitro release profile, and biodistribution rats. drug-loaded microparticles showed as tiny spheres under SEM had an average of 17 μm with 90% the ranging from 12 to 24 μm. loading efficiency 65% 6.5%, respectively....
Distribution, egg production rate (EPR) and abundances of four small copepods in genera Paracalanus Acartia were studied monthly from October 2005 to September 2006 outside Jiaozhou Bay, China. Biomass secondary also calculated show the importance these copepods. As predominant species, parvus bifilosa, occurred continuously this bay throughout year, with large abundance peaks late spring early summer. pacifica sporadically May, but July, it reached higher maximum than other species....
Solid electrolytes are one of the key challenges that hinder commercialization all-solid-state batteries. Most efforts have been made to advance development solid as separators, while catholytes, particularly redox-active has less extensively studied. The high loading catholytes in composite cathodes, facilitating ionic conduction, drastically decreases energy density battery. Here, we report an alternative strategy improve by using Li
Low-cost cathode materials with high energy density and good rate performance are critical for the development of next-generation solid-state Li-ion batteries (SSLIBs). Here, we report Li
Abstract Nanoparticle pollution has been shown to affect various organisms. However, the effects of nanoparticles on species interactions, and role traits, such as body size, in modulating these effects, are not well‐understood. We addressed this issue using competing freshwater phytoplankton exposed copper oxide nanoparticles. Increasing nanoparticle concentration resulted decreased growth rates community productivity (both abundance biomass). Importantly, we consistently found that had...
The species range of Calanus sinicus along the Chinese coast extends from Bohai Sea and Yellow in north to northern part South China south. subtropical seas southern mark edge C. . In coastal off eastern Hong Kong, appears first December, but densities comparable those East are reached only January February when temperature is <15°C. Density decreases March as increases. No individuals remain after May >25°C. average prosome length females collected that Sea, mid-March smaller than...
Aiming at the disadvantage (premature convergence) of ant colony optimization (ACO), a mechanism called pheromone trail centralization (PTC) is presented. The adjusts trails proportionally and facilitates exploration by increasing probability selecting solution components with low trail. It can avoid premature convergence ACO exploit more strongly solutions. results show that PTC are superior to existing useful improve performance any versions investigating functioning in traveling salesman...
Although many single- and bi-metal sulfides were reported as bifunctional catalysts for oxygen evolution reaction (OER), The catalytic activity of trimetal was seldom their mechanisms need to be further investigated. Herein, FeCoNi sulphide nanostructures (MS x , M [Formula: see text] FeCoNi) are grown on carbon paper OER electrodes alkaline water splitting. MS outperforms the state-of-the-art IrO 2 in 1[Formula: text]M KOH with a reduced overpotential 250[Formula: text]mV superior Tafel...
Alloy coatings can enhance the mechanical and electrochemical properties of engineering materials such as surface hardness, wear resistance, catalytic performance, corrosion resistance. The development testing alloy films requires extensive time experimentation due to non-monotonic variation many with composition large experimental space compositions, which increases rapidly number components in alloy. thin be reduced by analyzing compositions a single experiment. However, current film...
High rate (i.e., high current density) cycling has always been discouraged in the practice of Li-ion and Na-ion batteries because charging/discharging can expedite electromechanical degradation cathodes result dendrites formation on anodes. But is this a universal rule thumb for all rechargeable batteries? Our recent research Zinc-ion (ZIBs) shows that might not be case. ZIBs employing aqueous electrolytes show great promise large-scale energy storage due to their affordability,...
