This study makes a claim of utilizing the photothermal effect of graphene oxide nanosheets (GONs) to effectively produce various microbubbles in an optical microfiber system at infrared optical communications band. A low power continuous-wave light at wavelength of 1527-1566 nm was launched into the microfiber to form GONsdeposition which acted as a linear heat source for creating various microbubbles. Both thermal convection flow and optical gradient force were responsible for the driving force to assemble GONs onto the microfiber. This simple optical fiber system can be used for assembling other micro/nanoscale particles and biomolecules, which has prospective applications in sensing, microfluidics, virus detection, and other biochip techniques. ©2013 Optical Society of America. © 2013 Optical Society of America.

Electron-hole recombination is one of the major factors limiting the efficiency of ZnO-based photocatalysts. In this work, a 2-fold enhancement strategy was employed to suppress electron-hole recombination and boost photocatalytic efficiency. First, significantly enhanced photocatalytic activity of ZnO by introducing graphene oxide (GO) was systematically investigated. Hybrid photocatalysts with different weight ratios of ZnO to GO (from 0.95:0.05 to 0.70:0.30) were synthesized and characterized. The results indicated that when the proportion ratio of ZnO to GO reached 0.85:0.15, the as-synthesized ZnO-GO nanocomposite exhibited the maximum photocatalytic efficiency on methylene blue with an apparent rate constant κapp almost 10 times faster than that of pure ZnO under UV illumination. GO was suggested to enhance the photocatalytic activity of ZnO because of its great capability in dye adsorption and charge separation. Second, Pd nanoparticles were introduced to decorate ZnO-GO to produce generally better photocatalyst ZnO-GO-Pd nanocomposites. The junction between Pd and ZnO was believed to also effectively separate the photogenerated charges due to the metal-semiconductor diode effect. These two systems of ZnO-GO and ZnO-GO-Pd nanocomposites are expected to have a broad range of applications in environmental conservation. © 2014 American Chemical Society.

A novel cross-linked quaternized composite anion-exchange membrane based on poly(epichlorohydrin) (PECH) was prepared by a facile route. First, PECH was cross-linked with 2-methylimidazole and combined with a poly(tetrafluoroethylene) (PTFE) membrane to form cross-linked PECH/PTFE (CPECH/PTFE). Then, CPECH/PTFE was quaternized by 1-methylimidazole to obtain cross-linked quaternized PECH/PTFE (CQPECH/PTFE). 1H NMR and Fourier transform infrared spectroscopic data indicated that CQPECH was successfully synthesized, and the CQPECH/PTFE membrane had a dense and homogeneous structure demonstrated by the field-emission scanning electron microscopy. The results showed that the use of 2-methylimidazole as the cross-link agent could avoid the solubility of the composite membrane in water and dimethyl sulfoxide. With an increase of 2-methylimidazole, the solubility of the PECH ionomer was decreased. M-3, one of the CQPECH/PTFE membranes, showed good thermal properties (stable below 250 °C under an N2 atmosphere), excellent mechanical strength (a tensile strength of 67.3 MPa), moderate water uptake of 45.3%, and very low swelling degree of 9.01% at 30 °C. Besides, M-3 showed a hydroxide conductivity of up to 27 mS/cm and good long-term stability in a 1 M KOH solution at 60 °C for 15 days. In addition, a single H2/O 2 fuel-cell test using M-3 at 50 °C indicated a peak power density of 23 mW/cm2. These results suggested that the CQPECH/PTFE membrane had a good perspective for application in an alkaline fuel cell. © 2014 American Chemical Society.

With the development of mobile Internet, ecommerce extensions make the payment from the Internet to the mobile Internet, it brings convenience to people, while it also brings security issues. In order to solve the trust of the mobile e-commerce payment terminals, this paper uses twoway trust authentications between the clients and the certification center to protect the trust of the payment terminals, while based on k-CAA problem in GDH group, this paper proposed an efficient authentication scheme. In the standard model, the identity authentication protocol can resist posing attack in parallel reset attack. Due to the simple interaction, low storage capacity, high efficiency and good safety performance, the identity authentication protocol is more applicable to mobile terminal equipments which havelimited computing and storage capacity. © Atlantis Press and the authors 2015.

Hexagonal nickel hydroxide/nickel decorated on reduced graphene oxide (rGO&Ni(OH)2-Ni) has been prepared via easy one-step chemical precipitation method and subsequent annealing treatment. The results show that the thermal stability of Ni(OH)2 is enhanced by the incorporation of Ni. Besides, hexagonal Ni(OH)2-Ni nanoplate which can supply a short diffusion and migration pathway for electron and electrolyte ion contacts closely with the surface of rGO, resulting that the agglomeration of rGO is effectively prevented. Due to the good electrical conductivity of Ni, the incorporation of Ni can also improve the electrical conductivity of Ni(OH) 2. More importantly, the Ni (111) plane is grown after annealing treatment, which plays a key role in Ni for further improving the electrochemical activity of composite. Consequently, the rGO&Ni(OH) 2-Ni electrode exhibits high capacitance, high energy density, excellent rate capability, good cycle stability, etc. The advantages of easy preparation and excellent electrochemical performance imply the great potential application of rGO&Ni(OH)2-Ni in supercapacitors. Moreover, it is worthy noting that this work will offer a new approach for using metal nanoparticle in improving the electrochemical property of supercapacitor electrode material. © 2014 Published by Elsevier B.V.

To prevent the aggregation of graphene oxide (GO) during storage or application, montmorillonite (MMT) was used as the modifier, and MMT-pillared GO (GM) was prepared. The features of GM were characterized using Fourier transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy, energy dispersion X-ray spectrometry, atomic force microscopy and X-ray diffraction measurements. Then, a batch system was applied to study the adsorption behaviors of lead ions (Pb2+) and methylene blue (MB) by GM in single and binary systems. The results showed that GM possessed a higher Brunauer-Emmett-Teller (BET) specific surface area than GO. In a single system, the maximum adsorption capacities of GM for MB and Pb2+ were 350 and 285 mg g-1, respectively. With increasing the storage days, the BET specific surface area and the maximum adsorption capacity of GM remained approximately unchanged, while that of GO dramatically decreased. For a binary system, the presence of MB in water provides additional binding sites for Pb2+, promoting the adsorption of Pb2+ on GM. The presence of Pb2+ in water would compete with MB on GM during the adsorption process, resulting in a decrease in the adsorption of MB. The adsorption results recorded under different conditions indicated that this experiment was capable of the simultaneous removal of Pb2+ and MB using GM as the adsorbent. In addition, the pillared structure of GM greatly enhanced the noncovalent adhesion. © The Royal Society of Chemistry 2015.
