Voltammetric and Impedance studies of Phenols and Its Derivatives at Carbon Nanotubes/Prussian Blue Films Platinum Modified Electrode

Adekunle A.S., Arotiba O.A., Agboola B.O., Maxakato N.W., Mamba B.B., Ebenso E.E., North-West University, ZA

Phenols and the chlorinated and alkylated derivatives are classified as priority pollutants due to the health risk associated with their toxicity. Due to their constant presence in industrial waste and consequently their carcinogenic risk for [...]

Silicon and nickel nanoparticle size and morphology as a key to control the particle photoluminescence and photochemistry

Tvauri I.V., Parkhomenko Yu.N., Khubezhov S.A., Kaloeva A.G., Demeev Z.S., Bzaev A.O., Bliev A.P., Sozanov V.G., Magkoev T.T., University of North Ossetia, RU

The work studies the structural and photoinduced properties of silicon nanoparticles (NanoSi) obtained by plasmachemical and electrolytic techniques and the nickel particles deposited on aluminum oxide film in ultra-high vacuum.

Chemoselective Hydrogenolysis of Glycerol Catalyzed by Platinum on Carbonaceous Supports

Oberhauser W., Evangelisti C., Psaro R., Vizza F., Bevilacqua M., Filippi J., Lavacchi A., Marchionni A., Miller H.A., Machado B.F., Serp P., CNR-ICCOM, IT

Glycerol has been selectively converted into 1,2-propandiol in the presence of dihydrogen and heterogeneous Pt-based catalysts. These latter catalysts consist of small-size Pt-nanoparticles (NPs) (i.e. 1.0-1.5 nm,) obtained by a metal vapor synthesis, supported on [...]

Understanding Ru/CNT interactions: A rational design of Ru nanocatalysts

Machado B.F., Oubenali M., Axet M.R., Nguyen T.T., Tunckol M., Girleanu M., Ersen O., Gerber I.C., Serp P., Laboratory of Coordination Chemistry, FR

We report a detailed study on the nature of the ruthenium–carbon nanotube (Ru/CNT) interface in catalysts prepared from neutral Ru(0) organometallic precursors. Experimental data combined with density functional theory calculations allowed to conclude that both [...]

Organometallic Ruthenium Nanoparticles as a Model of study for Fischer-Tropsch Synthesis Reaction

Martinez-Prieto L.M., Philippot K., Chaudret B., CNRS, FR

The development of more active and/or selective catalysts for industrial application of the Fischer Tropsch Synthesis (FTS) process is still an ongoing field of research.In this context, Ru nanoparticles that are expected to provide more [...]

Gold nanoclusters for air purification applications

Mendoza E., Goldemar Solutions, US

Nowadays, public concern and the enforcement of environmental regulations by governments have made it necessary to develop versatile materials capable of efficiently eliminating a wide range of organic pollutants from both indoor and outdoor emissions. [...]

Investigation on Accelerated Ageing Techniques for IC Interconnect Structures in Context of Multicriterial Optimization of 3D SiP Design Flow

Janczyk G., Bieniek T., Instytut Technologii Elektronowej, PL

Many complex chips and novel smart nanosensor systems are developed as 3D structures like SiP on SoC to implement all requested functionality and achieve performance. Such structures incorporate several modules, materials forming 3D setup which [...]

A Clean and Green Route for the production of methacrylic acid and methacrolein from biofuel

Lin M.M., Grinberg J., Eng W., EverNu Technology, LLC, US

The modern consumption of fossil fuels for chemical production contributes to global warming and other nature disasters in recent years. Approximately 10% of U.S. crude oil imports are used to feed its chemical industry. There [...]

3D printing: How emerging materials, applications, and business models will disrupt manufacturing and enhance future innovation

Vicari A.C., Lux Research, US

From personalized medicine to personal drones, 3D printing – the additive manufacturing of objects by depositing and patterning successive layers of material – has been touted as an enabling platform for many compelling applications. Among [...]

$/W Costs of Thermoelectric Waste-Heat Recovery for Stationary Applications

LeBlanc S., Yee S.K., Scullin M., George Washington University, US

Interest in thermoelectrics for waste-heat recovery has flourished in recent years, but questions about cost and scalability remain unanswered. Prior work investigated the materials, manufacturing, and system costs and thermal and electrical transport factors that [...]
