In this study, the manufacturing methods and imaging principles of cone-shaped arrays of micro-nano structure films were examined. Because optical films fabricated using cone-shaped arrays of micro-nano structures generate a double diffusion and produce diverse light effects on light sources, these optical films can be used effectively to enhance optical efficiency and can thus be used widely i...

Cu/Ti3SiC2/C/BN/GNPs nanocomposites were prepared by vacuum hot-pressing (HP) sintering and hot isostatic pressing (HIP) sintering methods. Microstructures, mechanical and tribological properties of Cu/Ti3SiC2/C/BN/GNPs nanocomposites were investigated. Microstructures were examined by optical microscopy (OM), X-ray diffraction (XRD) and scanning electron microscope (SEM). Mechanical properties...

Small-angle neutron scattering (SANS) and neutron powder diffraction (ND) techniques were used to study quantitatively the effect of nano-sized precipitates and boron addition on the mechanical properties of low-carbon steels. SANS was used to evaluate nano-sized precipitates, smaller than about 600 A in diameter, and ND was used to determine the weight fraction of the cementite precipitates. F...

Epoxy resin is one of the most widely used thermosetting polymers and commonly applied in power electronics field. The intrinsic properties epoxy can be improved by introduction inorganic filler, thus fabricating a composite material. In this paper, different scales modified boron nitride (BN, 1 ?m, 10 ?m) were to improve thermal conductivity resin. surfaces BN modification silane coupling agen...

The existence of Single-wall C-nanocones (SWNCs), especially nanohorns (SWNHs) and BC2N/Boron Nitride (BN) analogues is discussed in organic solvents in cluster form. A theory is developed based on the bundlet model, describing distribution function by size. The phenomena present unified explanation in the model, in which free energy of (BC2N/BN-)SWNCs involved in cluster, is combined from two ...

In this paper, we have studied the hydrogen adsorption onto CNCs and BNNCs nano-cones using GCMC simulations. The effects of length and cone apex angle on adsorption property have been investigated. Our results show that with increasing the pressure and decreasing the cone length and cone apex angle except for CNC-300˚, the hydrogen adsorption onto the BNNCs and CNCs was increased. It was also ...

In this work, the electronic properties of BP and CSi Nano cones have been investigated by self-consistent reaction field (SCRF) method in water solvent at B3PW91/6-31G (d,p) level of DFT theory for study of  for interactions of 5-Fluorouracil Anticancer Drug with theses Nano cones. The percent of change of energy gap (%ΔEg) shows that the complex formation of 5-Fluorouracil with BP ...

To investigate non-bonded interaction of Phenanthrene and BN nanostructure, geometric structure of Phenanthrene and B12N12 nano-ring with B3LYP method and 6-31g* basis set are optimized by using ab initio gaussian quantum chemical package. The main purpose of this study was to evaluate changes of electronic properties of aromatic compound in presences Nano ring field. Therefore reactivity and s...

This paper presents the design and analysis of nano-structured gratings to improve the conversion efficiency in GaAs solar cells by reducing the light reflection losses. A finite-difference time domain (FDTD) simulation tool is used to design and simulate the light reflection losses of the subwavelength grating (SWG) structure in GaAs solar cells. The SWG structures perform as an excellent alte...
