The excessive concentration of NO_(2) in the atmosphere has gained considerable attention due to its damage to the environment and human health. Gas sensor technology has important application prospects in detecting atmospheric NO_(2) concentration. Restricted by its wide bandgap, pristine ZnO needs additional energy to power the electronic transition as a gas sensing material.

A liquid metal enabled corrosion sculpture technique for quickly fabricating complex pattems on aluminum substrate is proposed and experimentally demonstrated. According to the conceptual investigation, it is clarified that the width and the depth of a printed track are dominated by sculpture time and working temperature. The printed size can reach small values of 38 μm through controlling the sculpture time for 60 s. As the sculpture time was increased from 5 to 25 rain at 20℃, the depth of the fabricated pattern was improved from 13.3 to 25.6 μm. The sculptured depth of the pattern would increase from 13.3 to 106.9 μm when the sculpture time was fixed at 5 min and the temperature was raised from 20 to 60℃. To investigate the sculpture behavior in detail, the phases and microstructure of sculpture surface were quantitatively measured via a group of microscope imaging system with fundamental mechanisms interpreted. The present liquid metal sculpture method on aluminum substrate adds a new valuable soft tool for current metal engraving technology family.

Hydrolysis of olive oil catalyzed by Candida lipolytica lipase was investigated. The relative concentration of the components in the product was determined by using high performance liquid chromatography（HPLC）. Furthermore, a novel rapid method to detect the hydrolytic process of olive oil was developed based on the relationship between the acid value and the relative concentration of the different components.

under three-dimensional plane geometrical constraints ( X,Y,θ ), with two asymmetric achromatic sections, the combined three-section structural FODO-like magnet lattice design is adopted and finely optimized in the SSRF electron-beam transfer lines. The magnet lattice has high flexibility and robustness, and the Courant–Snyder parameters can be easily adjusted within a wide range to meet the requirements of transmission and injection for different operation modes of the linear accelerator, booster synchrotron, and storage ring. In this article, the main parameters of the linear optics design of the SSRF electron-beam transfer lines are described, involving the physical design criteria, the total geometrical layout, the magnet lattice, and the beam Courant–Snyder parameters matching. The studies of the variant beam dynamic simulation program calculations show that the design purpose of the efficient beam transmission and injection will be basically achieved.

Inherently anisotropic soil fabric has a considerable influence on soil strength. To model this kind of inherent anisotropy, a three-dimensional anisotropic failure criterion was proposed, employing a scalar-valued anisotropic variable and a modified general three- dimensional isotropic failure criterion. The scalar-valued anisotropic variable in all sectors of the deviatoric plane was defined by correlating a normalized stress tensor with a normalized fabric tensor. Detailed comparison between the available experimental data and the corresponding model predictions in the deviatoric plane was conducted. The proposed failure criterion was shown to well predict the failure behavior in all sectors, especially in sector II with the Lode angle ranging between 60° and 120°, where the prediction was almost in accordance with test data. However, it was also observed that the proposed criterion overestimated the strength of dense Santa Monica Beach sand in sector III where the intermediate principal stress ratio b varied from approximately 0.2 to 0.8, and slightly underestimated the strength when b was between approximately 0.8 and 1. The difference between the model predictions and experimental data was due to the occurrence of shear bending, which might reduce the measured strength. Therefore, the proposed anisotropic failure criterion has a strong ability to characterize the failure behavior of various soils and potentially allows a better description of the influence of the loading direction with respect to the soil fabric.

We use wavelet transform to analyze the daily relative sunspot number series over solar cycles 10-23. The characteristics of some of the periods shorter than - 600-day are discussed. The results exhibit not only the variation of some short periods in the 14 solar cycles but also the characteristics and differences around solar peaks and valley years. The short periodic components with larger amplitude such as ～27, ～ 150 and ～360-day are obvious in some solar cycles, all of them are time-variable, also their lengths and amplitudes are variable and intermittent in time. The variable characteristics of the periods are rather different in different solar cycles.
