The ZnO and Ti:ZnO thin films were deposited on ordinary glass, quartz glass, substrates by sol‐gel spin coating. The atomic percent (at.%) of Titanium (Ti) in ZnO is varied from 1 to 6. The deposited thin films were characterized by Grazing Incidence X‐ray diffraction (GIXRD) for structural determination, High ‐ resolution Scanning Electron Microscopy (HRSEM) to determine microstructure, optical transmittance to know the type of optical transition in the films. The structure of the ZnO and Ti:ZnO films was determined by Grazing Incidence X‐ray diffraction (GIXRD). The ZnO films were observed to be crystallizes in Hexagonal wurtzite structure with (002) orientation, where as Ti:ZnO films were amorphous. The intensity of (002) decrease with increasing Ti at.%. The grain size is 20 nm and is decreasing to 10 nm with increasing Ti at.%. The HRSEM images of Ti (1%):ZnO and Ti (6%):ZnO thin films reveals that the films contain nanoflakes of uniform size. These flakes contain spherical nanoparticles of uniform size. The samples were tested for their sensitivity for 300 and 600 ppm of acetone and is maximum for films contain 1 at. % of Titanium.

The finite element numerical simulation of hot compression deformation process of B93 aluminium alloy was carried out by DEFORM-3D software. Besides, the microstructure characteristics of deformed specimens in different regions and the relationship between non-uniform strain and dynamic recrystallisation during deformation were analysed by experimental study. The results show that the hot compression process of B93 aluminium alloy obviously exhibits a nonuniform characteristic of deformation, the region with the largest equivalent strain is the most prone to deformation. Also, in the largest equivalent strain zone, dynamic recrystallisation reacts the most complete, and the grain size reaches the minimum value. Nonuniform deformation show a rising tendency with the increase of strain rate and deformation temperature, and the influence of strain rate on nonuniform deformation is slightly greater than that of deformation temperature. The most suitable hot working process for the alloy is 410~430°C/0.001~0.01s-1.

The operation performance of the axial piston pump is affected by external environment pressure, and its conditions at low suction pressure are less studied. The oil model and fluid dynamic model of the axial piston pump are developed and a novel approach for predicting the operation performance of such machines at low suction pressure based on this model is presented. It was found that the inlet pressure of the suction chamber changes linearly with the environment pressure. Compared to the present data from the product manual, this approach is proved to be valid and is used to predict the maximum operating speed and suction pressure at other environment pressure, therefore the low-pressure operating performance map is enriched for the referring of more users of the pump. In future, this study provides a new method for the prediction and the design guide of pump operation at low suction pressures.

We investigate a new design of the defective zigzag (10,0) carbon nanotube (CNT) as a hydrogen sulphide (H2S) sensor using density functional theory (DFT). Herein, the defective zigzag (10,0) CNT obtained by removing one to five carbon atoms from the pristine zigzag (10,0) CNT to create simultaneously one to five of the single vacancies located around the nanotube axis. The formation energy and the dissociation energy inform us that all defective zigzag (10,0) CNT systems are stable. Then, the adsorption energy shows that these defective systems can adsorb the H2S molecules. Furthermore, an unexpected finding has also been found in this study. The presence of the H2S molecules on the defective (10,0) CNT arises the band gap of these systems.
