Properties of Linear Low Density Polyethylene Reinforced with Multi-walled Carbon Nanotubes by Cryogenic Ball-Milling

Narh K.A., Terife G., New Jersey Institute of Technology, US

The combination of high aspect ratio, small size, very low density, and more importantly, excellent physical properties, such as extremely high mechanical strength and stiffness, high electrical and thermal conductivity, make carbon nanotubes (CNTs) perfect [...]

Advanced p- and n-Dopable Polymer Supercapacitors

Kim Y.-G., Kinlen P.J., Jung J.H., Mbugua J., Besic S., Birschbach M., Tregre G., Nguyen H.-L., Crosslink, US

Metallic conductive PAC 1003, an inherently conductive polymer product of Crosslink, has been developed to have remarkably high electrical conductivity of >1000 S/cm which can be applied to advanced polymer supercapacitor designs. The metallic conductivity [...]

Catalytic activities of sputtered p-type Cu2O electrode in connection with TiO2 thin film for dye degradation

Wu K.R., Hung C.H., Yeh C.W., Sun J.C., Hsu C.J., National Kaohsiung Marine University, TW

In this study, a p/n-type photoelectrocatalytic (PEC) cell was used to enhance the photocatalytic (PC) and PEC activities towards the degradation of methylene blue (MB) solution under ultraviolet (UV) irradiation. The PEC cell consists of [...]

Novel supported catalytic materials based on multiwalls carbon nanotubes

Koltypin Y., Savilov S.V., Gedanken A., Landau M.V., Bar-Ilan University, IL

We present a method that allows proper control of the nanoscale curvature of the external surface in multiwall carbon nanotubes (MWCNT) and shown its effect on the properties of Ni/MWCNT catalyst. After removal of residual [...]

Neiva L.S., Simões A.N., Oliveira J.B.L., Andrade H.M.C., Gama L., Federal University of Campina Grande, BR

This work has as aim the development of Ni catalysts supported in α-Al2O3/ZnO, Al2O3/Fe2O3 and Al2O3/ZrO2 to be applied in to catalytic reaction of the steam reforming of the methane. The Al2O3/ZnO, Al2O3/Fe2O3 and Al2O3/ZrO2 [...]

Palladium Quantum Dots Sensitized TiO2 Nanotube Arrays for Enhancing Photoelectrocatalytic Hydrogen Generation

Gong J.J., Lin C.J., Xiamen University, CN

In order to further enhance photoeletrocatalytic reactivity, it is desirable to develop a facile and effective technique to obtain high quality Pd@TNTAs with homogeneous dispersion and small enough particle size down to few of nm [...]

Oxygen Reduction Reaction Enhancement of PdCo/C Electrocatalysts Driven by Oxidation Treatment

Wang K-W, National Central University, TW

One of the key issues for polymer electrolyte membrane fuel cells (PEMFCs) is to reduce or replace expensive Pt cathode catalysts. Although the development of non-Pt, such as Pd-Co catalysts for the oxygen reduction reaction [...]

Pt-Au Core/Shell Nanorods: Preparation and Applications as Electrocatalysts for Oxygen Reduction Reaction

Liu C-W, National Central University, TW

Nanostructured materials have been studied intensively due to their board potential applications in the energy field. A great deal of effort has been devoted to developing high efficient nanocatalysts for oxygen reduction reaction (ORR). In [...]

Estimate effective interaction potentials from the static structure factor in pure fluids and nanocolloids

Oprisan A., Oprisan S.A., Oprisan A., Oprisan S.A., Teklu A., Hegseth J., College of Charleston, US

The direct visualization and analysis of critical fluctuations in pure fluids in microgravity, and concentration-driven interface fluctuations in nanocolloids provide invaluable information about cooperative phenomena and the role played by fluctuations in mixing, phase separation, [...]

Fast gelation of self-assembling peptide nanofibres triggered by electromagnetic radiation heating

Mazza M., Gaisford S., McCharty D., Uchegbu I.F., The School of Pharmacy, University of London, UK

We report a method for the preparation of peptide nanofibre gels prepared by a rapid heating/cooling cycle employing electromagnetic radiation heating. An amphiphilic peptide having a C16 chain attached via an esteric link was used [...]
