The number of potential uses of science and/or technology at the nanoscale level in the food and food ingredient industry is growing rapidly with ongoing research in a variety of application areas. Many applications offer [...]
In our previous study, we first prepared TiO2 nanoparticle-encapsulating poly(vinyl chloride) (TEPVC) aiming at breakthrough to enhance the dispersibility of TiO2 nanoparticles in PVC matrix to maximize catalytic activities of TiO2 nanoparticles. The present study [...]
Heterogeneous reactions of atmospheric gases on aerosol particles may play an important role in atmospheric chemistry. However, the kinetics and mechanisms of adsorption and reaction of atmospheric gases on aerosol surfaces are not well understood. [...]
The development and applications of nanomaterials have presented a unique problem to environmental scientists and risk assessors. Until now, the models and paradigms used to predict the behavior of chemicals in the environment and thereby [...]
Engineered nanomaterials differing in size, shape, surface area and composition are used in research, industrial, and consumer applications. Because of their unique structure and size the need exists for toxicological profiles of nanoparticles as a [...]
There are increasing concerns about the health and environmental impact of nanomaterials. The study of Sun et. al 2006 provided the evidence of facilitated bioaccumulation of As(V) in carp in the presence of titanium dioxide [...]
Carbon nanotubes are emerging as potential tools in drug delivery nanocarriers to target specific cell types and carbon cages filled with metal molecules may improve MRI microimaging. The present paper reviews the current state of [...]
Bioremediant cleaning products are investigated for every day use by consumers in their homes. Nano-components such as biosurfactants, enzymes, metaloenzymes, and chelating agents are derived from Sea Kelp and are the result of naturally occurring [...]
Some considerable effort has recently been displayed by manufacturers, researchers, regulatory bodies, professional organizations, NGOs, and other interested parties addressing how nano-particles and their manufacture should be environmentally regulated. The term environment here is used [...]
This paper describes an approach to assess atmospheric pollutant in the troposphere and their spectral characteristic signatures by using high-spectral and spatial resolution ASTER data and its analysis of variance with in-situ data obtained using [...]
The influence of direct current electric fields on the possible electrokinetic delivery of a nano-iron slurry in clay for the purpose of fast and effective remediation of soil contaminants has been tested. Nano-iron can be [...]
The presentation contains two innovative applications of nano-sized materials for environmental application: 1) Pd catalysts for wastewater treatment. The new ferromagnetic nano-sized Pd catalysts have proved effective for selective dechlorination of industrial wastewater. Extraction by [...]
We have all heard about the marvelous advances being made in the use of nanomaterials in imaging, cancer therapy and controlled release pharmaceuticals. What is less well known is the role of nanotechnology in prevention [...]
