Spray deposited copper zinc tin sulphide (Cu2ZnSnS4) film as a counter electrode in dye sensitized solar cells

21.10.2014 | Sanjay Kumar Swami; Neha Chaturvedi; Anuj Kumar; Nikhil Chander; Viresh Dutta; D. Kishore Kumar; A. Ivaturi; S. Sent ..., Physical Chemistry Chemical Physics, 2014

Stoichiometric thin films of Cu2ZnSnS4 (CZTS) were deposited by the spray technique on a FTO coated glass substrate, with post-annealing in a H2S environment to improve the film properties. CZTS films were used as a counter electrode (CE) in Dye-Sensitized Solar Cells (DSCs) with N719 dye and an ...

Evolution of mechanical properties during cure for out‐of‐autoclave carbon‐epoxy prepregs

18.10.2014 | Khalil Vora, Tien Vo, Mohammad Islam, Mohammad Habibi, Bob Minaie, Journal of Applied Polymer Science, 2014

ABSTRACT Extent of cure and rheological properties were obtained for out‐of‐autoclave materials, Cycom 5320‐8HS and Cycom 5320‐PW, for the manufacturer recommended cure cycle using differential scanning calorimeter and encapsulated sample rheometer (ESR), respectively. Rheological properties ...

Sensors, Vol. 14, Pages 19402-19440: Femtosecond Laser Fabrication of Monolithically Integrated Microfluidic Sensors in Glass

17.10.2014 | He, Fei ; Liao, Yang ; Lin, Jintian ; Song, Jiangxin ; Qiao, Lingling ; Cheng, Ya ; Sugioka, Koji, Sensors, 2014

Femtosecond lasers have revolutionized the processing of materials, since their ultrashort pulse width and extremely high peak intensity allows high-quality micro- and nanofabrication of three-dimensional (3D) structures. This unique capability opens up a new route for fabrication of microfluidic ...

Deep-Sea Field Test of the CH4 Hydrate to CO2 Hydrate Spontaneous Conversion Hypothesis

17.10.2014 | Peter G. Brewer; Edward T. Peltzer; Peter M. Walz; Elizabeth K. Coward; Laura A. Stern; Stephen H. Kirby; John Pinkston, Energy & Fuels, 2014

We have carried out a small-scale deep-sea field test of the hypothesis that CH4 gas can be spontaneously produced from CH4 hydrate by injection of a CO2/N2 gas mixture, thereby inducing release of the encaged molecules with sequestration of the injected gas. Pressure cell studies have shown ...

Catalytic Non‐Thermal Plasma Decomposition of Ethylene by Using ZrO2 Nanoparticles

16.10.2014 | Mani Sanjeeva Gandhi, Young Sun Mok, Plasma Processes and Polymers, 2014

In the present work, ZrO2 nanoparticles loaded on glass wool (GW) were employed for catalytic and plasma‐catalytic decomposition of ethylene. Unlike ZrO2 pellets, nanosized ZrO2 was found to exhibit catalytic activity for the decomposition of ethylene. Some carbon‐containing by‐products like ...

Dendritic Ionic Liquids Based on Imidazolium‐Modified Poly(aryl ether) Dendrimers

16.10.2014 | Tianyi Qin, Xuying Li, Jinping Chen, Yi Zeng, Tianjun Yu, Guoqiang Yang, Yi Li, Chemistry - An Asian Journal, 2014

Abstract A series of dendritic ionic liquids (DILs) based on imidazolium‐modified poly(aryl ether) dendrimers IL‐Br‐Gn (n=0–3) were synthesized by a modified convergent approach and “click” chemistry. The resulting DILs exhibited high thermal resistance with decomposition temperatures up to ...

Room Temperature Growth of Ultrathin Au Nanowires with High Areal Density over Large Areas by in Situ Functionalization of Substrate

16.10.2014 | Subhajit Kundu; Annamalai Leelavathi; Giridhar Madras; N. Ravishankar, Langmuir, 2014

Although ultrathin Au nanowires (∼2 nm diameter) are expected to demonstrate several interesting properties, their extreme fragility has hampered their use in potential applications. One way to improve the stability is to grow them on substrates; however, there is no general method to grow these ...

A Simple and Highly Efficient Method for Synthesis of Ce3+‐activated Borogermanate Scintillating Glasses in Air

15.10.2014 | Xin‐Yuan Sun, Zi‐Piao Ye, Yun‐Tao Wu, Pan Gao, Ri‐Hua Mao, Zhi‐Jun Zhang, Jing‐Tai Zhao, Journal of the American Ceramic Society, 2014

Fast Ce3+‐activated borogermanate scintillating glasses with the density of 5.58–5.67g/cm3 were synthesized by melt quenching method in air atmosphere for the first time. The optical transmittance and X‐ray absorption near edge spectroscopy results confirm that Ce4+ ions can be effectively ...

Microfluidic Western Blotting of Low-Molecular-Mass Proteins

15.10.2014 | Rachel E. Gerver; Amy E. Herr, Analytical Chemistry, 2014

We describe a microfluidic Western blot assay (μWestern) using a Tris tricine discontinuous buffer system suitable for analyses of a wide molecular mass range (6.5–116 kDa). The Tris tricine μWestern is completed in an enclosed, straight glass microfluidic channel housing a photopatterned ...

Rheology of suspensions of solid particles in power‐law fluids

15.10.2014 | Rajinder Pal, The Canadian Journal of Chemical Engineering, 2014

Abstract The viscous behaviour of concentrated suspensions of solid particles in non‐Newtonian powerlaw fluids is discussed here. After a brief review of the existing models, new models are presented for the constant shear‐rate relative viscosity of concentrated suspensions with powerlaw ...
