Studies on the kinetic properties of photocatalytic degradation of phenol in water using ZnO nanopowder as a photocatalyst

Tao Y., Cheng Z.L., Ting K.E., Yin X.J., Singapore Polytechnic, SG

In recent years, advanced oxidation processes (AOPs) have been proved to be one of the most effective methods to remove organic pollutants from water and wastewater. These processes are based on the generation of the [...]

Applying Basic Risk Management Principles to Nanomaterial Processes

Geraci C.L., National Institute for Occupational Safety and Health, US

Health, safety, and environmental issues continue to be a high priority area to be addressed during the commercialization of nanomaterials or nanomaterial-enabled products. Facilities engaged in the production or use of engineered nanomaterials, specifically nanoparticles, [...]

Nanomaterials Employed in Effective Tumor Treatment

Liang X-J., National Center for Nanoscience and Technology of China, CN

Chemotherapy is one of most effective cures to treat different of malignant tumors. Cisplatin is a chemotherapeutic compound commonly used in clinics, however, acquired resistance confines its application in chemotherapeutics. To overcome the acquired resistance [...]

New method for the caracterization of abrasion-induced nanoparticle release into air from nanomaterials

Golanski L., Guiot A., Tardif F., CEA, FR

Nanotechnologies are emerging around the world. Nanoparticles are finding new industrial applications every day. Due to the variety of nanoparticles, toxicology studies will take time to establish the dangerousness of every kind of nanoparticle. Today [...]

Electron instabilities in nanoclusters, nanostructures and inhomogeneous nanomaterials: bottom up approach

Kocharian A., California State University Los Angeles, US

Inhomogeneous nanomaterials with strong local electron correlations are creating a new world-view in condensed matter physics [1-4]. These materials with intrinsic ihomogeneities have electronic and magnetic properties that are widely different from the conventional materials. [...]

Morphology Changes and Defects in Carbon Nanoparticles Due to Different Atom Arrangements

Sharma A., Sharma R., Kwon S., Sharma A., Sharma R., Innovations And Solutions Inc, USA, US

Motivation: Pentagon and heptagon fullerene carbon nanostructures (CNT) have potentials in superlight weight industries. CNT have structural defects caused by irregular atom arrangement during CNT growth. For better use, it needs modifications to remove defects. [...]

Carbon Nanotubes and Grephene for Solar Cells

Li Z., Dervishi E., Saini V., Bourdo S., Biris A.S., University of Arkansas at Little Rock, US

Carbon nanotubes and graphene represent attractive materials for photovoltaic devices. Single wall carbon nanotubes (SWNTs) bear many superior properties for photovoltaic application such as a wide range of direct bandgaps matching the solar spectrum, strong [...]

Size distribution determination of nanoparticles and nanosized pores by small-angle X-Ray scattering on a multi-purpose X-ray diffractometer platform

Bolze J., Rekhi S., Macchiarola K., Litteer B., PANalytical B.V., NL

We present the small-angle X-ray scattering (SAXS) technique for the investigation of crystalline and amorphous materials on a mesoscopic length scale ranging from ca. 1 - 100 nm. Dry powders or dispersions of inorganic and [...]

The SURVISMETER – a Green Technology in Service

Singh M., Bhanumati S., Shukla A., Shukla S.S., Shukla A., Shukla S.S., University of Delhi, IN

Viscosity is a measure of stickiness and the reverse is fluidity. It is a valuable data for all liquids in the oil, lubricant, paint, polish, food, beverage, cosmetic, biosolvents, drugs and pharma, polymer, nanomaterials, and [...]

Silica Nanosprings – A Novel Nanostructured Material for Hydrogen Storage

Norton M.G., McIlroy D.N., Corti G., Miller M.A., Washington State University, US

Hydrogen storage for transportation applications remains a challenge. Current approaches are still short of published goals, in particular in being able to operate at acceptable temperatures. Physisorption, or non-dissociative approaches, where the hydrogen is stored [...]
