    Abstract Sheng Jing Decoction (SJD), as a traditional Chinese medicine prescription, is mainly be used to treat male infertility. However, the pharmacological functions and molecular mechanisms of SJD are poorly understood. In this study, we investigated the functions of SJD on spermatogenesis and sperm motility and explored the potential mechanisms involved. Here, we demonstrated that high, medium, and low doses of SJD are effective in restoring the impairments of the whole body and testicular tissue by cyclophosphamide inducing and to rescue the damage of testicular tissue cells including Sertoli cells and germ cells. SJD can partly restore the decrease in sperm concentration, sperm vitality, sperm motility, and normal sperm morphology rate in oligozoospermic mouse models. Ki67 staining analyses confirm SJD can promote testicular tissue cell proliferation. Real-time RT-PCR analyses also reveal that SJD can upregulate the expression of proliferation-associated gene

    Abstract In order to improve the mechanical durability, polyurethane (PU) needs to be modified to enhance the tribological and anti-corrosion properties. In this work, we fabricated a series of PU composite coatings reinforced with functionalized graphene (FG) and functionalized graphene oxide (FGO). The structural and morphological features of the composite coatings were characterized by Fourier transform infrared spectroscopy, Raman spectroscopy, X-ray diffraction, transmission electron microscopy and scanning electron microscopy. The results showed that the dispersion and compatibility of graphene and graphene oxide were improved via chemical modification. Moreover, they effectively enhanced the tribological and anti-corrosion properties of PU composite coatings, whose optimized additive range was between 0.25 wt% and 0.5 wt%. The effect depends on the balance of lubrication and barrier of fillers and cracks generated by them. Finally, in comparison with FG/PU coatings, the FGO/PU coatings exhibited a better tribological property but worse anti-corrosion property owing to the abundant oxygenated groups of GO. They led to stronger interfacial interactions between FGO and the PU matrix, but destroyed the graphene lattice structure to some extent.

    Abstract Patterned hydrophobic Ni–P alloy films consisting of orderly and regular micro-nanoscale particles were fabricated through the synergistic effect of electrochemical deposition and chemical deposition. Ni–P alloy films were deposited for different times and characterized by scanning electron microscope (SEM). It was confirmed that the addition of reducing agent induced the formation of nanoscale particles, in contrast with pure Ni film deposited by single electrochemical deposition. As “point-discharge effect”, the current density was higher at the edge of the nanoscale particles, and Ni ions would be deposited at the particles through the “point-discharge effect”. Then the Ni–P alloy films grew by “reducing–discharging” process. The X-ray photoelectron spectroscopy (XPS) was used to detect the composition and valence states of these alloy films. The existence of oxidation state of element P in these films corresponding to that in H₂PO₃–, also gave direct evidence for the occurrence of chemical deposition, during the electrochemical deposition process. The prolongation of deposition time could provide more time for the patterned morphology to grow up. The surface roughness, evaluated by surface profilometer, increased as the deposition time extension. And these films showed gradually increased hydrophobic properties with the increase in deposition time.

    Abstract The nucleation mechanism of the preparation of a Ni–P deposit by the synergetic effect of electrochemical deposition and chemical deposition was studied using an electrochemical analysis method. Cathode polarization and chronoamperometry were performed to explore the effect of the reducing reaction (chemical deposition) on the electrochemical Ni deposition. It was found that the addition of reducing agent to the solution induced depolarization phenomena and decreased or removed the double electric layer capacitance. The chronoamperometry experimental data were analyzed and fitted according to the Scharifker–Hills rule to discover the difference in mechanism between the Ni nucleation and Ni–P nucleation. The morphology of Ni–P and the pure Ni deposits was measured by TEM and SEM demonstrating the ball-like particle shape of Ni–P and flat pure Ni deposits. Based on these experimental results, the nucleation mechanism was illustrated in which the active Ni atoms, produced by electrochemical deposition, act as a catalyst for the reduction of the nickel ions with the reducing agent NaH2PO2 on the cathode surface. The occurrence of the reducing reaction of the nickel ions with NaH2PO2 hindered the in-plane growth of crystalline nickel particles, generating the ball-like particle shape of the deposit. This work provides researchers new insights into the nucleation and growth process of synergetic deposition and offers novel ideas for the fabrication of functional materials by liquid deposition.

    Abstract Both of surface topography and chemical composition play important roles in affecting the adhesive force and friction force in micro/nano-electromechanical systems (M/NEMS). Two effective approaches of reducing adhesion and friction of contacting interfaces are to create patterned surface and lower surface energy, which are especially beneficial for M/NEMS production yield and product reliability. Diamond-like carbon (DLC) films with high hardness, low friction coefficient and good wear resistance have aroused particular interest as protective film. Also, ionic liquids (ILs) display better tribological properties than that of conventional lubricants, such as PFPE and X-1P. In this article, we present a novel method to fabricate the micro-patterned DLC-IL films by combination of by combination of inductively coupled plasma (ICP) etching method, magnetron sputtering technology and dip-coating method. DLC films with different packing density micro-grooves were prepared by controlling the photolithography design. The morphologies and surface chemical states of DLC and DLC-IL films were characterized by atomic force microscope (AFM), XPS and Raman. The adhesion and friction on the as-prepared DLC and DLC-IL films were studied by colloidal probe mounted on AFM cantilever in contact mode. The microtribological behaviors of the DLC and DLC-IL films were evaluated by UMT-3 tribometer in a ball-on-plate reciprocating mode. The experimental results showed that adhesive force and friction force of the DLC films with micro-grooves reduced effectively with increase of groove area density and incorporation of thin ILs film. The corresponding synergetic anti-adhesion and friction reduction mechanisms of surface pattern and chemical modification were discussed and clarified with emphasis. The lowered adhesion and friction force were attributed to two factors including (1) the reduced real area of contact between DLC films and colloidal tip; (2) incorporation of thin ILs films to avoid direct contact between DLC films and colloidal tip, which facilitating the sliding of colloidal tip on DLC films.

    Abstract High mechanical strength superhydrophobic Ni-Cu-P alloy coatings with strong adhesion force were one-step galvanostatically electrodeposited onto low alloy steel substrates, from a citrate- and sulphate-based bath. Surface morphologies of as-deposited Ni-Cu-P coatings were investigated by Scanning Electron Microscope (SEM). The chemical composition, structure, mechanical properties and adhesive/hydrophobic properties of coatings were characterized by energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), nano-indenter, and contact angle meter, respectively. Results showed that Ni-Cu-P coatings had cauliflower-like micro-nano structures and exhibited stable hydrophobicity under different pH values and high adhesive properties without any chemical modification. Hardness test results showed that hydrophobic Ni-Cu-P alloy coatings exhibited a high hardness of about 8.5GPa. The deposition process of coatings was proposed to illustrate the formation of cauliflower-like micro-nano structures. The mechanism of the hydrophobic and high adhesion characteristic of this surface was explained by Cassie impregnating model. This method of fabricating hydrophobic surface has potential in practical applications such as micro-droplet transportation, corrosion protection and nano patterning.

    Abstract We fabricate a cellulose sponge with stable superoleophobicity (θoil > 150°) under water and superhydrophilic wettability (θwater ≈ 0°) under oil without any further chemical modification for oil–water emulsion separation. The cellulose sponge shows superoleophobicity to various oils under water and possesses stable superoleophobicity in corrosive liquids like strong acid, alkali and salt solution. The sponge is made from the dissolution and regeneration of cellulose powder which is green, low cost, simple and easy to scale up. The natural hydrophilicity of the cellulose ensures its excellent under-water superoleophobicity and antifouling properties. The double layer construction of different pore sizes, which contains a top-layer with a pore size lower than 1 μm and a sub-layer with a pore size larger than 3 μm, ensures that the oil phase is resisted and the water phase easily and quickly permeates the sponge. Our cellulose sponge can separate oil–water mixtures, with >99.94% separation efficiency, solely using gravity and has excellent antifouling properties.
