Ce3+ doped Bi2O3 hollow needle-shape with enhanced visible-light photocatalytic activity was successfully prepared via the method of chemical precipitation using Bi(NO3)·5H2O and Ce(NO3)3·6H2O as the source of bismuth and cerium, HNO3 as solvent and NaOH as precipitants, respectively and after calcination at 500 ℃ for 2 h. The morphology and elemental composition,crystal form,purity and specific surface area of the hollow needle Bi2O3 were characterized by SEM-EDS, XRD, BET and FT-IR. The photocatalytic properties of the as-obtained samples were measured by UV-vis diffuse reflection spectroscopy and photochemical reactor. As a result, the obtained Bi2O3 hollow needle-shape doped with 5 wt% Ce shows good morphology, α-phase, stronger absorbent for visible light and good photocatalytic property. Under the simulated visible light of 300 W, the photodegradation rate of tetracycline over HNBCe can reach to 89.1%,which is higher than that of commercial Bi2O3 nanoparticles and Bi2O3 hollow needle-shape.

The chemical composition and aluminum speciation of sludge incineration residue （SIR） were determined. Cementation of aluminum from sulfuric acid solution using SIR was studied. The results showed that acid-soluble inorganic aluminum was the predominant component in the sludge, and the total leached aluminum increased from 62.2% to 92.9% after incineration. Sulfuric acid dosage and reaction time were found to affect aluminum recovery positively. Conversely, the increase in temperature significantly inhibited recovery reactions. The optimized leaching condition was 1.66 g sulfuric acid per gram of SIR with a reaction time of 3 hr at 20°C, resulting in the highest aluminum leaching rate of 96.7%. Compared to commercial aluminum sulfate solution coagulants, the leaching solution demonstrated higher CODCr, turbidity and color removal efficiency for textile wastewater.

Bamboo weevil larva has excellent performance on cutting plant fiber. From quantitative analysis of the mandible incisor profile of bamboo weevil larva, it was found that the primary cutting edge of incisor is close to a standard circular arc, which is helpful for improving the cutting efficiency of mandible incisor. Inspired from the geometrical characteristics of the bamboo weevil larva＇s incisor, a new bionic mincing blade was designed and manufactured. The experimental results of chopping equal Chinese cabbages showed that, when the rotational speed was 1400 rpm, the mincing energy consumption of bionic blade was 12.8% lower than conventional blade and the chopping efficiency of bionic blade was 12.5% higher. Meanwhile, the mincing capacity of bionic blade was 36 kg.h-1, which was 1.5 times of that of the conventional blade, 24 kg.h^-1. The material weight loss rate was 11.2 % lower than that of conventional blade. The qualification rate of the minced cabbage chopped by bionic blade was 93,3%, which was higher than the 85.7% of conventional blade. Therefore, the bionic blade could obviously promote the quality of product and the working efficiency of mincing machine. These results would provide guidance for designing cutting component of vegetable choppers, succulence cutter and other food processing machines.

Mole rat （Scaptochirus moschatus）, a soil-burrowing mammal, can efficiently dig soil using its fore claws. The profile curves of its claw toe provide excellent structure for digging. In this paper, a biomimetic stubble-cutting disc was designed by learning from the geometrical characteristics of the mole rat claw toes. To compare the structural strength and working eff^- ciency of the biomimetic disc and the conventional stubble-cutting disc, three-dimensional （3D） models of the discs were built and numerical analyzed in ABAQUS. In the dynamic soil cutting model, soil was modeled as an elastic-plastic material with elastic parameters, including Young＇s modulus, Poisson＇s ratio and Drucker-Prager criterion, which were obtained from triaxial tests. A general contact algorithm was used to simulate the interaction between rotary disc and soil. In FEA models, for the combined action of normal and friction stresses, the stress on the biomimetic disc is 34.33% lower than that of the conventional disc. For only the normal stress, the stress on the biomimetic disc is 22.64% lower than that on the conventional one. The magnitude of soil stress in biomimetie disc cutting model is 6.87% higher than that in conventional disc. The FEA results indicate that the biomimetic disc performs better in structural strength and cutting efficiency.
