Nanofluids were fabricated by employing nanoparticles with different dielectric properties as modifiers to improve the dielectric performance of the mineral oil. Breakdown voltages under AC and lighting impulse stresses were measured to evaluate breakdown strength of these nanofluids. The results indicated that the addition of semiconductive nanoparticles to the base oil can improve the breakdown...
Transmission and distribution transformers are a critical part of the electricity generation and distribution network. The potential consequence of transformer failure can cause operation disruption and financial losses. In recent years, magnetic nanoparticles have been used to enhance the dielectric breakdown strength of transformer oil. Considering the inherent magnetic property of the magnetite...
A new class of colloidal dielectric fluids is formulated with the objective of enhancing the dielectric performance of mineral oil for application in power system. TiO2 nanoparticles modified by different organic reagents are suspended by means of sonication. Dielectric strength measurements are carried out under AC for a number of different colloidal systems with varying particle mass fraction. It...
A data acquisition system is designed for biosensor based on nanopore, used the chip of TI TMS320VC5509A and Cypress Cy7C68013A. The major goal for our system is to convert analog data to digital data and transfer data to computer. Our system can be used in biological signal data convert already. The experimental results already proved the availability of the system. Because of using of the DSP chip...
We report an effective method to synthesize gold nanorods with tunable longitudinal extinction peak wavelength from 781 to 955 nm depending on the amount of NaCl added. Those as-prepared gold nanorods are helpful for bioimaging.
Organically modified silica nanoparticles, doped with photosensitizers, are synthesized, characterized and used for photodynamic therapy (PDT) of cancer. These nanoparticles were uptaken by tumor cells in vitro and the effect of photon-induced toxicity was demonstrated.
We report a sensitive nanosensor based on a micro-fluidic chip and nanoparticles to detect low concentrations of DNA. The emission of CdSe/ZnS-QDs linked with single strand DNAs was quenched by gold nanoparticles linked with the complementary sequences after hybridization. Sensitively detected signal of DNA was obtained from a 100 mum capillary.
Today's technology is tuned towards faster, smaller and better efficiency. This trend has resulted in tremendous heat being generated in microelectronics components and if not properly managed, it can result in failure of microelectronics components. A critical issue is the removal of this heat generated. We report here a new type of nano thermal interface material (Nano-TIM) using the electrospinning...
