摘要： A hollow spherical cerium dioxide nanomaterial, preparation method and application thereof; wherein the preparation method uses glucose as a carbon source, urea as a precipitant, cerium trichloride as a cerium source, and water as a solvent to prepare a cerium dioxide/carbon composite material by a hydrothermal method, and then, a hollow spherical cerium dioxide nanomaterial with a multi-shell layer structure is obtained by calcination in a muffle furnace. By adjusting the amount of urea and the calcination temperature, a number of shell layers of the material can be adjusted. Moreover, in the nanomaterial, the number of shell layers can be adjusted, large spacing exists between shell layers, specific surface area can be increased, wherein contact area of the material with an electrolyte increases, but also structural collapse caused by a volume expansion of an electrode material during charging and discharging can be alleviated, and the electrochemical performance is effectively improved.

摘要： A material with pine-branch like samarium oxide/graphene/sulfur gel structure, and a preparation method and use thereof. The material is reduced graphene oxide carrying pine-branch like samarium oxide on the surface to form a cross-linked gel structure, and sulfur is loaded on the gel structure. The preparation method includes: subjecting graphene oxide and a samarium salt to hydrothermal reduction to prepare a reduced graphene oxide/samarium precursor; under an inert atmosphere, thermolysing the reduced graphene oxide/samarium precursor to obtain a reduced graphene oxide/pine-branch like samarium oxide gel; and melting and diffusing the sulfur onto the reduced graphene oxide/pine-branch like samarium oxide gel. The material with pine-branch like samarium oxide/graphene/sulfur gel structure greatly improves the electrochemical performance of lithium-sulfur batteries.

摘要： The present invention relates to a method for preparing a simply prepared, safe, nontoxic, and biodegradable modified starch; the present invention further relates to use thereof as an adsorbent in adsorbing heavy metal ions and organic compounds, and belongs to the technical field of modified starch material. Starch is used as raw material and modified with thiourea and tungsten chloride; the starch binds to heavy metal ions through a series of coordination or chelation, and thus produces a heavy metal ion adsorption effect; a starch-based carbon composite is prepared, i.e., a modified starch composite. The simply prepared, environmentally friendly, and recyclable modified starch adsorbent with excellent performance and higher practical value effectively removes He ions and such organic compounds as methylene blue from the wastewater; the modified starch adsorbent is expected to develop into a novel water treatment agent due to low loss rate, biodegradability, and recyclability.

摘要： The present invention further discloses an application of Saccharomyces cerevisiae in the fermentation of a second generation fuel, ethanol, with a straw lignocellulose biomass hydrolysate as a raw material. Experiments prove that the strain of the prevent invention has an efficient co-fermentation capacity of C6/C5 while tolerating multiple inhibitors, and can consume all the glucose and xylose to produce ethanol; and the sugar-alcohol conversion rate is up to 0.43 g g−1. The strain and screening strategy used in the present invention provide technical reference and basis for the further breeding of a Saccharomyces cerevisiae strain which has a superior fermenting property and is produced by the second generation fuel, ethanol.

摘要： A supercapacitor contains the zwitterionic polymer hydrogel electrolyte. A change rate of a capacitance retention of the supercapacitor, relative to a specific area capacity at 25° C. is less than 25% at extreme temperature. When temperature is increased to 60° C. or reduced to −30° C. the specific area capacity is changed to 178 mF cm−2 and 134 mF cm−2, which are 104% and 78% of that at 25° C. indicating an excellent electrochemical property at the extreme temperature.

摘要： An optical fiber inclination measurement apparatus and a differential inclination measurement system are provided, which is related to the field of monitoring technology. The apparatus includes a supporting mechanism with a base and a base frame, a swinging mechanism with a pendulum, a cycloid, and a first reflective film is disposed on the pendulum. The measurement mechanism includes a first optical fiber, and an end surface of the first optical fiber is disposed opposite to the first reflective film. During an earthquake generating process, a landform changes and the pendulum swings, resulting in changes in displacement. The end surface of the first optical fiber together with the first reflective film form a Fabry-Perot cavity. The cavity length of the Fabry-Perot cavity changes before and after the landform deforms, and an angle of inclination is equal to a value obtained by dividing the cavity length variation of the Fabry-Perot cavity by the pendulum length.
