Both MD simulations and experimental studies have shown that liquid and gas flow through carbon nanotubes with nanometer size diameter is exceptionally fast. For applications in separation technology, selectivity is required together with fast flow. [...]
Optimized synthesis of new cellulose-GMA materials via radical and physical chemical activation, their chemical composition determination and derivatization quantification. Structural solid state NMR and IR ATR characterizations. Derivative screenings for possible use in filtration of [...]
Titania based aerogels are nanoscopic pore-solid architectures with high surface area and a continuous mesoporous network fashioned from interconnected nano-quasicrystallites building blocks that make them attractive for various (photo)catalysis based applications . Besides the role [...]
Ultrasound in a liquid phase cause mass and heat transfer across the liquid through cavitational processes which act as nanoreactors to generate unstable mechanical equilibrium. The effect of 1 MHz ultrasound on the inactivation of [...]
The applications of carbon nanotubes (CNTs), a novel and important class of nanomaterials, can change paradigms of various research areas. Although biomedical applications of CNTs are increasing, their putative cytotoxicity has not been substantially addressed. [...]
Applications of nanomaterials (e.g., silicon dioxide (SiO2) nanoparticles) are ubiquitous. Thus, environmental and occupational exposure to these nanoparticles could pose potential health risk. SiO2 microparticles are toxic in animals in vivo and SiO2 nanoparticles are [...]
Nanomaterials have been increasingly used in industrial applications (e.g., drug delivery, additives to drugs and cosmetics). Because of their wide use, occupational exposure to nanomaterials and nanoparticles may pose as health risks. Recent studies have [...]
Although the Project on Emerging Nanotechnologies estimates that there are already over 500 nanotechnology-based consumer products on the market, few published data are available to support thorough nanomaterial safety assessments. To address questions of product [...]
Nanotechnology has been compared to the industrial revolution in its scope of applications and ability to dramatically transform new and existing technologies. Nanotechnology is a quickly emerging field where the toxicological effects on human and [...]
This study was undertaken to address the current deficient knowledge of cellular response to nano sized particle exposure. The aim of this study was to investigate the in vitro responses of human bronchial epithelial cells [...]
The fate of nanoparticles in commercial products at the end of product life is not entirely clear. This uncertainty, coupled with the unknowns regarding the potential for risks to human health and the environment, could [...]
Analysts have estimated that the worldwide market for nanoparticles will be about 340 billion Euro in 2011 which would rank it alongside the automobile and microelectronic industries. However, potential impact of these new materials on [...]
Considerable uncertainty exists regarding full-scale manufacturing costs, occupational risks, and probable future regulatory standards for various single wall carbon nanotube (SWNT) manufacturing processes. Monte Carlo models have been developed to investigate these implications and compare [...]
Recent discoveries of various forms of carbon nanostructure have stimulated researches on their applications and hold promise for applications in medicine and many other related engineering areas. While carbon nanotubes (CNT’s) are already being produced [...]
Interaction between the nanoparticles and nervous tissue in the process of the damage healing is the object of study in the present work. Laboratory animal (rat) was put into deep narcosis. The Nervus ischiadicus was [...]
Cell model systems in vitro play vital roles in recent advances in toxicological and tissue engineering research. They are particularly versatile in facilitating signaling and related mechanistic studies. Although the 3-D cell models better simulate [...]
In this paper we will describe our results of CNT ingestion in in vitro cell cultures. We will present AFM pictures of the observed impact of CNT on cell growth. We will describe the bio-nano [...]
There is general agreement that in vitro cell model systems offer many advantages over in vivo model systems in elucidation of cell signaling and other mechanisms underlying a toxicant’s effect. While the 3-D cell models [...]
Transition metal oxides are desirable alternatives to precious metals based catalysts for CO oxidation since they are less costly. Several nanosize iron oxides were prepared by using Headwaters Technology Innovation (HTI) NxCat® colloidal chemistry nanotechnology. [...]
