A precise single point diamond turning (SPDT) CNC software is developed on the Windows platform using QT4.8.1 graphical interface development tools, with the calling of the UMAC library function. This paper introduces the hardware design of precise SPDT CNC system, the communication method between QT and UMAC, the design and implement of the main interface of the software, the implement of the basic motion control, the process of each module and the software three-dimensional (3D) simulation of this system. The result of the 3D simulation shows that the design of the system is reasonable and the system is able to achieve good processing results. Such a numerical control system has a certain economic value and prospects for industrial applications.

The triangular flake and wire shaped silver-water (Ag-H2O) nanofluids with good suspension have been achieved via one-step and two-step method, respectively. The thermal conductivity and viscosity of two kinds of Ag-H2O nanofluids were both higher than the based fluids (H2O). The results showed that the thermal conductivity of the two kinds of Ag-H2O nanofluids increased with the content of Ag nanoparticles and temperature increasing. The rheological behaviours analysis showed that two kinds of Ag-H2O nanofluids observed the Newtonian behaviours whose viscosity were close to the water and increased with Ag incorporation. The thermal conductivity of the triangular flake shaped nanofluids was higher than that of the wire shaped nanofluids in the same mass fraction and temperature while the viscosity was in reverse. The effect mechanism of solid content, temperature and morphology on the thermal property of Ag-H2O nanofluids has been discussed in detail.

The puffing glutinous rice starch (PGRS) could be obtained by adding glutinous rice starch (GRS) with the moisture content of 21% into the bulking machine and expanding at 225°C and under 0.75 MPa. The gelatinised GRS had increased adhesive strength. Compared with gelatinisation by heating and adding alkali, gelatinisation by puffing was easier to control and had a higher degree of starch gelation. Thermogravimetry (TG) and differential thermogravimetry (DTG) showed that PGRS had improved thermal stability. The starch granule was disintegrated after puffing and therefore more hydrophilic hydroxyls were exposed. The PGRS had increased water-solubility, which was shown in IR spectrometry with a broad and strengthened peak of O-H stretching vibration. Scanning electron micrograph (SEM) found that the PGRS granules were shaped in rough surface, which would have a strong affinity for water. Therefore, it might be widely applied in the adhesive and pharmaceutical industries.

In this paper, the urchin-like cupric oxide-water (CuO-H2O) nanofluids has been prepared using two-step method via ultrasonic concussion which the CuO nanoparticles are uniformly dispersed in deionised water (DI water), and the urchin-like CuO nanoparticles has been obtained via hydrothermal method. The structural properties of CuO nanoparticles are characterised via XRD and SEM analysis, indicating that the nanoparticles have uniform size and good dispersibility. The thermal conductivity and the surface tension of the urchin-like CuO-H2O nanofluids have been studied in detail. The thermal conductivity and surface tension of the urchin-like CuO-H2O nanofluids are both higher than the based fluids, and they increased with the mass fraction increasing. The heat transfer performance of heat pipe using urchin-like CuO nanofluids are experimentally measured on the condition of air cooling. The results show that the start-up time of the heat pipes using nanofluids are greatly lower than that of DI water, and reduce with the mass fraction increasing. The start-up temperature rise of heat pipe becomes larger than that of the heat pipe filled with DI water, and increased with the mass fraction increasing. The utilisation of nanofluids as working medium can enhance the heat transfer performance of the heat pipe.

Based on micromechanical characters of Z-pinned composite laminate, a finite element model is established to predict progressive failure properties of Z-pinned composite laminate under tension loading. For Z-pinned composite laminates, four failure modes: matrix cracking, matrix compressive failure, fibre breakage and fibre kinking are included in the present model. The calculated failure strength is compared with those obtained from experiments and other model. Failure mode pictures and stress-strain curves under tension load are obtained. The results indicate fibre breakage due to the matrix cracking is the main failure mode in Z-pinned carbon/epoxy composites under tension.

In situ nanofibrillar reinforced blends with thermoplastic poly (vinyl alcohol) (TPVA) as matrix and poly (lactic acid) (PLA) as dispersed fibrils were successfully prepared by a simple extrusion-stretching process. The microstructure and mechanical properties of the melt-processed TPVA/PLA composites were characterised by Fourier transform infrared spectra, thermal gravimetric analysis, scanning electron microscopy and tensile tests. The results indicated that there are hydrogen bonding between TPVA and PLA which enhance PLA dispersion as well as the interfacial adhesion with TPVA matrix. PLA content was varied from 10 to 30 wt. % resulting in reinforced TPVA matrices with fibrils of 78~150 nm. Compared with TPVA, TPVA/PLA composites exhibit remarkable improvement in mechanical properties and thermal stability.

Owning to their extensive practical application, the controllable synthesis of well-faceted TiO2 crystal with high percentage of reactive facets has attracted increasing attention. When adjusting the concentration of HF at 120 mM and 240 mM, anatase TiO2 crystal and plate with exposed {001} facets had been fabricated on the amine-grafted graphene oxide (AGO) via a facile hydrothermal method. The influence of experiment conditions on the morphology of the final products was investigated in detail. The results showed that the morphology of TiO2 crystal on AGO transforms cube-like structure into truncated tetragonal bipyramid structure when extending the reaction time, and the size of TiO2 crystal were affected by the molar ratio of F/Ti. In addition, the dispersion of TiO2 plate were improved by amino or oxygen-containing group on AGO sheet.

The mesostructured WO3 film on tungsten was investigated by anodic oxidation in ethylene glycol electrolytes containing low concentrations of ionic liquids (EMim.BF4, 0.6-1.6 vol. %). The surface structure of the WO3 film as prepared can be adjusted by changing the time, potential and temperature of anodisation, and the concentration of ILs and water in the electrolyte. The sample was characterised by X-ray diffraction (XRD) and field-emission scanning electron microscope (SEM) respectively. A self-organised mesostructured WO3 can be obtained under optimised parameters. The mesostructured WO3 film is arranged in sections of arrays with an average granular diameter of 30 nm.
