Sewage discharge produced by homes and industries contains both oil and water-soluble components. In order to remove oil from water, materials with specific wettability can be used;however, these materials cannot remove dissolved contaminants from water. In this research, we prepared a superhydrophobic Cd S cotton for water purification. This material has the ability to adsorb different types of oil due to its non-wettability(WCA = 152°). Moreover, its response behavior towards visible light enables it to remove water-soluble pollutants as well. The highest oil absorption rate of superhydrophobic Cd S cotton is nearly 30 times, and it can absorb light below 564 nm and produce ·OH to degrade water soluble pollutants. Finally, based on Mott-Schottky curve,the position of Fermi energy level was determined(–0.55 e V). Also, the positions of valence and conduction bands were calculated based on the analysis of band gap which helps in proving photoelectric response characteristics.

It is a challenge to endow the material with the ability to pollutants degradation while maintaining the oil/water separation performance. Herein, the mixed dispersion of BiOBr photocatalyst and silicone sol was adsorbed in melamine foam. Superhydrophobic BiOBr-silicone aerogel(WCA=154°) was obtained through the transfer melamine foam to an autoclave and reaction at 80℃ for 20 h. The prepared superhydrophobic BiOBr-silicone aerogel can effectively remove the water soluble pollutants which remain within the water phase after oil/water separation. The band gap of the superhydrophobic BiOBr-silicone aerogel was calculated to be 2.71 eV, which shows sensitivity to visible light(458 nm). Through mechanism analysis, it is found that the VB position of BiOBr is at 1.07 eV and the position of CB is at-1.64 eV. Finally, we prepared a superhydrophobic BiOBr-silicone aerogel(5 cm×5 cm×3 cm) for the verification of the large scale preparation.

Fifteen novel N-sulfonyl aromatic amide derivatives were designed and synthesized, and the structures were characterized by 1H-and 13C-NMR, EA and HRMS. The crystal structures of compounds I-8 and I-9 were obtained from X-ray diffraction: I-8 is of triclinic system, Mr = 372.35, space group P2_(1/n) with a = 7.9151(10), b = 8.5637(11), c = 12.2022(15) A, β = 86.865(2)o, V = 807.09(18) A^(3), Z = 2, F(000) = 384, D_(c) = 1.532 g/cm^(3), the final R = 0.0408 and wR = 0.1068 for 2836 unique reflections with 2435 observed ones(I > 2σ(I)). I-9 belongs to triclinic system, M_r = 407.39, space group P2_1/n, with a = 8.4911(8), b = 8.6053(9), c = 14.5808(15) A, β = 77.1190(10)o, V = 995.44(17)A^(3), Z = 2, F(000) = 416, D_(c) = 1.359 g/cm^(3), the final R = 0.0567 and wR = 0.1779 for 3475 unique reflections with 2392 observed ones(I > 2σ(I)). The preliminary bioassay results indicated that the target compounds showed weak nematicidal activity, while compound I-5 displayed good fungicidal activity against Colletotrichum capsici with the inhibition rate of 61.7%.

The traditional superhydrophobic materials are not ideal for treating residual pollutants after oil-water separation. In this paper, a simple and economical method was developed for the fabrication of multi-functional superhydrophobic materials PDVBx/TiO2 composites, through in situ polymerization. The performance of the superhydrophobic composite was studied. The results showed that the low surface energy of PDVB2.5/TiO2 composite with the micro-nano scale roughness would result in excellent superhydrophobicity. In addition, the PDVB2.5/TiO2 composite exhibits optimum effect on the degradation of methyl orange(MO) with the degradation efficiency of 97.8%. What is more, the applications of the composite materials could be expanded to other fields, such as the degradation of drug ciprofloxacin hydrochloride(CIP). Finally, we expanded the application of the PDVBx/TiO2 composites to tribology, and found its excellent performance in reducing wear and antiwear.

We propose the sub-picosecond chirped soliton pulse propagation in copcave-dispersion-flattened fibers （CDFF）. The effects of pulse characteristics and the fiber dispersion parameters on propagation characteristics of the chirped soliton pulse are numerically investigated in the CDFF by the split-step Fourier method （SSFM）. The unchirped soliton pulse can stably propagate with unchanged pulse width in the CDFE The temporal full width at half maximum （FWHM） of the chirped soliton performs a damped oscillation with the increase of propagation distance. The period and amplitude of the oscillation increase with the increase of the chirp parameter ｜C｜. The effect of high-order dispersion （β3-β6） on soliton propagation characteristics can be neglected. The soliton pulse slightly broadens with the increase of propagation distance and still maintains soliton characteristics when the fiber loss （ATT） is further considered. The variation of root-meansquare （RMS） spectral width with propagation distance is opposite to that of the temporal width. The output spectrum of soliton has a single peak for the unchirped case, while has multi-peak for chirped case. The temporal width of the soliton obviously increases with the increase of the initial width, decreases with the increase of dispersion peakD0 of the fiber, and slightly increases with the decrease of dispersion coefficients k1 and k2 of the fiber.

Two new compounds, [Ni2（L1）（Py）6]Py·CH3OH（1） and [Ni3（LZ）2（PY）4]·2DMF（2）（H4L1=N,N＇-bisalicyl-bisthiocarbamide; H3L2=3-hydroxyl-2-naphthalene thiosemicarbazide; Py=pyridine; DMF=dimethyl fumarate）, based upon two thiosemicarbazone ligands have been obtained and characterized by elemental analysis, Fourier transform infrared（FTIR） and X-ray diffraetion（XRD）. Compound 1 possesses a binuclear cluster, in which the bisalicylbisthi- ocarbamide acts as a hexadentate bridge. Compound 2 exhibits a linear trinuclear cluster with the triply-deprotonated ligand acting as pentadentate bridge. C--H…O, C--H…π and C--…S weak interactions further link these molecules to form interesting supramolecular networks.
