Development of the Electro-Friction Effect in the Semiconductor Particles / Thermoplastic Resin Composite Film

Fuwa T., Su H., Yanaka R., Takase R., Kobayashi K., Kawai T., Sakurai K., Anzai H., Kuroda S., Gunma University, JP

Electro-Rheological (ER) fluid is the suspension of polarizable particles in an insulating solvent and has the characteristic that the apparent viscoelasticity changes when an electric field is applied from the outside. This phenomenon is caused [...]

Fine textured composite low friction coatings with combined corrosion protection ability

Becker-Willinger C., Kalmes P., Bentz D., INM - Leibniz Institute for New Materials, DE

A new class of multifunctional low friction coatings combining a low coefficient of friction of µ 1000 h in the neutral salt spray test on mild steel have been developed. The coatings possess a fine [...]

Directional wetting on chemically stripe-patterned surfaces

Kooij E.S., Jansen H.P., Zandvliet H.J.W., Univ. Twente, MESA+ Inst. Nanotechnology, NL

The ability to control liquids at surfaces is highly relevant for many application areas, including for example the performance and reliability of inkjet nozzles. Generally, the wettability of solid substrates can be modified both by [...]

Microscopic “Slide-Snap” Receding Contact Line Dynamics on Superhydrophobic Surfaces

Yeong Y.H., Milionis A., Bayer I.S., Loth E., University of Virginia, US

Receding angles have been shown to have great significance when designing a superhydrophobic surface for applications involving self-cleaning. Although apparent receding angles under dynamic conditions have been well studied, the microscopic receding contact line dynamics [...]

Carbon Nanotube Bucky Papers with Tailored Porosity for Filtration Applications

Esawi A.M.K., Ramadan A.R., ElNur R., The American University in Cairo, EG

In this work, Carbon Nanotube Buckypapers (CNT-BPs) were prepared using vacuum filtration. Morphology and pore size distribution were investigated using scanning electron microscopy (SEM) and nitrogen gas adsorption. The prepared BPs were subsequently exposed to [...]

Membrane Dehydrators for Efficient Water Contamination Control in Lubricating and Hydraulic Fluid

Majumdar S., DiNetta L.C., Compact Membrane Systems, Inc., US

Ingression of water or ambient moisture over time into industrial lubrication and hydraulic fluid systems causes major operational and maintenance problems. Water can be present in such systems as free, dispersed and dissolved water. The [...]

Directional liquid gating by hydrophilic/hydrophobic Janus membranes

Tian X., Aalto University, FI

The ability to gate (i.e., allow or block) droplet and fluid transport in a directional manner represents an important form of liquid manipulation and has tremendous application potential in fields involving intelligent liquid management. We [...]

Cellulose Acetate Nanocomposite Membranes for Water Desalination Applications

Ramadan A.R., Esawi A.M.K., El Badawi N., Mahmoud M., The American University in Cairo, EG

Interest in the use of membranes in water desalination applications has been increasingly developing due to their numerous advantages. Among the various desalination technologies, ‎Reverse Osmosis (RO) membrane processes are steadily becoming more reliable and [...]

Multi-layer Thermal Barrier Coating of a New Architecture

Kuzanyan A.A., Kuzanyan A.S., Petrosyan A.G., Petrosyan S.I., Kuzanyan A.A., Kuzanyan A.S., Petrosyan A.G., Petrosyan S.I., Stathopoulos V., Institute for Physical Research, National Academy of Sciences, AM

Thermal barrier coating (TBC) provide a thermal and corrosion insulation layer able to decrease thermal loads on the surface of major operating metallic parts of gas turbines. Advanced thermal barrier coating systems have the following [...]

An Electrodeposition Method for Preparing (Ni-Cu) /(Cu-Ni) Multilayers on magnesium alloy from ionic liquid

Guo J., Guo X., Guo J., Guo X., Dong J., Wang S., Gong J., Zhu R., Ding W., Shanghai Jiao Tong University, CN

Abstract A single bath of ionic liquid electrodeposition method has been developed for the preparation of (Ni-Cu)/(Cu-Ni) multilayers on AZ91D magnesium alloy. The technique has been used to make multilayers with a composition of (92.47at.%Ni-7.53at.%Cu) [...]
