Interests: include studying the biological activity and toxicity of nanomaterials, the underlying mechanisms, and the relationship between the biological activity and the physiological properties of nanomaterials such as size, surface chemistry, et al. I am also interested in optimizing nanomatereials’ properties by chemical approaches for the laboratory and industrial applications. I am especially interested in developing nanocontructs for biological and medicinal applications such as gene delivery, cancer targeting and drug delivery

Special Issue Information

Dear Colleagues,

Nanotechnology has a wide range of applications in fields such as medicine, cosmetics, energy, communication, and pollution remediation. About 1827 nanomaterial-based consumer products are now on the market, suggesting human exposures to nanomaterials and environmental release and accumulation of these materials. At the same time, nanomaterials are specially tailored to suit various biological and medicinal needs, such as crossing cell membranes and physiological barriers, passive and active targeting, reducing toxicities, and prolonging blood circulation. However, the incompatibility between broad testing needs and limited resources requires computer modeling for assistance. Modifications of nanomaterials, such as changing their surface chemistries, core materials, shapes, and sizes, modify their physicochemical properties, and thus affect their activities and functions. These activities include, but are not limited to, nanomaterial–biomolecule interactions, nanomaterial–cell interactions, cell targeting, cell function regulations, drug delivery, gene regulations, nanotoxicity in vitro and in vivo, environmental applications, catalysis, nanocomputations, and other applications. This Special Issue on “Impacts of Nanomaterial Modifications” aims at providing a platform for discussing the bioactivities and diverse functions of nanomaterials, the relationships between these activities and nanostructure, and the application of nanomaterials with designed activities. We invite authors to contribute original research articles or comprehensive reviews covering the most recent progress and new developments in the following topics, which include, but are not limited to:

  • Design, synthesis and functionalization of nanomaterials with different surface chemistries, core materials, shapes, and sizes, as well as quality control;
  • Bionanomaterial design and synthesis;
  • Cancer-targeting nanocarriers;
  • New methodologies for assessing nanoparticle activity, medical use, and other functions;
  • Regulations of nanomaterial bioactivities and other functions by modulation of nanostructure, and related mechanisms;
  • Combined effects of nanomaterials with other components (such as drugs, organic or inorganic pollutants) in vitro and in vivo, and the related mechanisms;
  • Applications of nanomaterials with designed activities and functions;
  • Computation modeling of nanostructure–activity relationship and prediction.

Nano-modification is a prospective method for improving the electrical properties of transformer oil. In most situations, transformer oil combined with cellulose paper is used to construct an insulation system for power equipment, such as power transformers. However, the influence of nanoparticles on the electrical performance of oil-impregnated paper is still unclear. Therefore, in this paper, we identify the failure characteristics of both fresh and nano-modified oil/paper. Specifically, the accumulative failure characteristics of nano-oil-impregnated paper (NOIP) are experimentally determined. The space charge distribution and trap characteristics of fresh paper and NOIP were measured, and the effect of nanoparticles on the space charge behavior are then analyzed. Finally, we measure the microstructure of fresh paper and NOIP subjected to repeated impulses. The test results indicate that nano-titanium oxide (TiO2) particles have a limited effect on the breakdown voltage of NOIP. However, the particles can dramatically improve the resistant ability of NOIP against repeated impulses. For the NOIP with a nano-concentration of 0.25 g/L, the improvement reaches 62.5% compared with fresh paper. Under repeated applications of impulse voltages, the space charge density of NOIP is much lower than that of fresh paper. The deep trap density of NOIP is much higher than that of fresh OIP, whereas shallow trap density is relatively lower. Micropores are generated in paper insulation subjected to repeated impulses. The amount of the generated micropores in NOIP is lower than that in fresh paper. Nano-TiO2 particles suppress the accumulation of space charge in the oil paper insulation, which weakens the electric field distortion in the dielectric. However, nanoparticles reduce the accumulative damage caused by repeated impulses. The above two points are considered the main reasons to improve the resistant ability against repeated impulses.
