Cu films with thickness of 630-1300nm were deposited on glass substrates without heating by.DC magnetron sputtering in pure Ar gas. Ar pressure was controlled to 0.5, 1.0 and 1.5Pa respectively. The target voltage was fixed at 500V but the target current increased from 200 to 1150mA with Ar pressure increasing. X-ray.diffraction, scanning electron microscopy.and atomic force microscopy.were used to observe the structural characterization of the films. The resistivity.of the films was measured using four-point probe technique. At all the Ar pressures, the Cu films have mixture cry.talline orientations of [111], [200] and [220] in the direction of the film growth. The film deposited at lower pressure shows more [111] orientation while that deposited at higher pressure has more [220] orientation. The amount of larger grains in the film prepared at 0.5Pa Ar pressure is slightly.less than that prepared at 1.0Pa and 1.5Pa Ar pressures. The resistivities of the films prepared at three different Ar pressures represent few differences, about 3-4 times of that of bulk material. Besides the deposition rate increases with Ar pressure because of the increase in target current. The contribution of the bombardment of energetic reflected Argon atoms to these phenomena is discussed.

China has been developed into one of the most active regions in terms of both fundamental and applied research on magnesium （Mg） and its alloy. in the world from a solid base laid by.its prominent metallurgist and materials scientists over the past decades. Nowaday., a large number of y.ung-generation researchers have been inspired by.their predecessors and become the key.participants in the fields of Mg alloy., which consequently.led to the establishment of China y.uth Scholar Society.for Magnesium Alloy. Research in 2015. Since then, the first two China y.uth Scholars Sy.posiums on Mg Alloy. Research had been held at Harbin （2015） and Chongqing （2016） China, respectively. A number of crucial research inter- ests related to fundamental and applied Mg research were discussed at the conferences and summarized in this short perspective, aiming to boost far-reaching initiatives for development of new Mg-based materials to satisfy.the requirements for a broad range of industrial employ.ents. Herein, four main aspects are included as follows： i） Plastic deformation mechanism and strengthening strategy. ii） Design and development of new Mg-based materials, iii） key.service properties, and iv） New processing technologies.

Owing to its viscoelastic nature, axon exhibits a stress rate-dependent me- chanical behavior. An extended tension-shear chain model with kelvin-Voigt viscoelas- ticity.is developed to illustrate the micromechanical behavior of the axon under dy.amic torsional conditions. Theoretical closed-form expressions are derived to predict the de- formation, stress transfer, and failure mechanism between microtubule （MT） and tau protein while the axon is sheared dy.amically. The results obtained from the present an- aly.ical solutions demonstrate how the MT-tau interface length, spacing between the tau proteins, and loading rate affect the mechanical properties of axon. Moreover, it is found that the MTs are more prone to rupture due to the contributions from the viscoelastic effects. Under the torsional force, the MTs are so long that the stress concentrates at the loaded end where axonal MTs will break. This MT-tau protein dy.amics model can help to understand the underly.ng pathology.and molecular mechanisms of axonal injury. Additionally. the emphasis of this paper is on the micromechanical behavior of axon, whereas this theoretical model can be equally.applicable to other soft or hard tissues, owning the similar fibrous structure.

Flexible strain wearable sensors have attracted considerable attention due to their advantages of low cost, lightweight, high sensitivity.and good flexibility. However, the strain sensors are easy.to be damaged in an extreme humidity.environment or by.the wearer’s sweat in the process of use, resulting in detection disorder or even a short circuit. Furthermore, preparation of sensors with stable properties under extreme environments is one of the most important research directions. To fill this gap, a flexible sensor was prepared by.using poly.rethane and carbon nanotubes, then modified by.poly.opamine and 1H,1H,2H,2H-perfluorodecane-mercaptan. A ty.ical tunnel model was used to explain the working mechanism of the sensor, the sensitivity.of the sensor is also explained and evaluated by.the tunneling theory. The results show that the sensor has good sensitivity.(the sensor has a stable sensing signal output under a strain range from 2% to 300%) and stability.over 8500 cy.les. At the same time, the sensor has good superhy.rophobicity. the water contact angle reaches 152°, and it is still stable in a humid environment. Moreover, this sensor shows excellent performance in monitoring human joint motion (such as finger, elbow, wrist and knee) and phy.iological signals (such as speaking and drinking). This work provides an effective design method for the sensor which can be applied in a high humidity.environment.

A model GM （grey.model）（1,1） for forecasting the rate of copper extraction during the bioleaching of primary.sulphide ore was established on the basis of the mathematical theory.and the modeling process of grey.sy.tem theory. It was used for forecasting the rate of copper extraction from the primary.sulfide ore during a laboratory.microbial column leaching experiment. The precision of the forecasted results were examined and modified via ＂posterior variance examination＂. The results show that the forecasted values coincide with the experimental values. GM （1,1） model has high forecast accuracy. and it is suitable for simulation control and prediction analy.is of the original data series of the processes that have grey.characteristics, such as mining, metallurgical and mineral processing, etc. The leaching rate of such copper sulphide ore is low. The grey.forecasting result indicates that the rate of copper extraction is approximately.20% even after leaching for six months.
