Research development of aluminum removal in chromium compound production

The Chinese Journal of Nonferrous Metals (2013)

Qiang Guo

The solid phase method and liquid phase method for aluminum removal in the chromium compound production were reviewed.The special emphasis was placed on lime free roasting process.Magnesioferrite(Mg(Fe,Al)2O4),sodium aluminosilicate(NaAlSiO4),silicic acid,aluminum magnesium sodium salt(Na4MgAl2Si3O12) are the major phases of aluminum containing compound.Certain amounts of silica dioxide or aluminum oxide and such additives,depending on the chromium containing material,are added to control the molar ratio of SiO2 and Al2O3 in order to form aluminum containing compound.The liquid phase methods is relative to the alkali concentration.For decomposition of aluminates in low alkali solution,carbonate process benefit for the production of easy filterable aluminum hydroxide with little content of chromate.For decomposition of aluminates in high alkali solution,aluminum hydroxide is obtained by seed composition following by extraction of great amount of alkali metal hydroxide and decrease of alkali/aluminum ratio.Finally,the problems and development of aluminum removal process were pointed out and analyzed.

Measurement of resilience in Chinese older people

International Nursing Review (2015)

Fang Yang Junhua Bao Xiuxiu Huang Qiang Guo Graeme D Smith

Background Resilience has been identified as a personal construct that may contribute to the process of healthy ageing in older people. To date, no measurement instrument has been tested to evaluate resilience in C hinese older people. Aim To examine the psychometric testing and clinical application of the C hinese version of the Resilience Scale ( RS ) in C hinese older people. Methods A descriptive cross‐sectional study design was used. Forward and backward translation procedures were used to obtain semantic equivalence of the original E nglish version of the RS . Content validity was examined by identified experts, followed by exploratory factor analysis, item‐to‐total correlation, C ronbach's α coefficients and test–retest reliability. Results The 25‐item C hinese version of Resilience Scale ( RS‐CN ) was fully completed by 461 C hinese older people. C ronbach's α for the total C hinese version of the Revised Resilience Scale was 0.95, with a range of 0.85–0.89 for the sub‐scales. Item‐to‐total correlation coefficients ranged from 0.51 to 0.75 and items were excluded with item‐to‐total correlations coefficients lower than 0.4. The test–retest reliability of the total scale was 0.80, sub‐scale test–retest reliability ranged from 0.61 to 0.620. The exploratory principal component analysis with varimax rotation revealed RS‐CN to have a four‐factor structure. Conclusion The RS‐CN is a valid and reliable instrument for the measurement of the concept of resilience in C hinese older people. The results of this study provide cross‐cultural evidence for the potential application of this scale in C hinese older people. Implications for nursing and health policy Greater insight into the psychological constructs of resilience in C hinese older people can lead to international comparisons and to the potential development of interventions for this population around the world.

Matching Glass-Forming Ability with the Density of the Amorphous Phase

Science (2008)

Y. Li Qiang Guo J. Kalb Carl V. Thompson

The density of the amorphous phase of metals is generally thought to be related to glass formation, but this correlation has not been demonstrated experimentally to date. In this work, systematic deflection measurements using microcantilevers and a combinatorial deposition method show a correlation between glass-forming ability and the density change upon crystallization over a broad compositional range in the copper-zirconium binary system. Distinct peaks in the density of the amorphous phase were found to correlate with specific maxima in the critical thickness for glass formation. Our findings provide quantitative data for the development of structural models of liquids that are readily quenched to the amorphous state. The experimental method developed in this work can facilitate the search for new glass-forming alloys.

Onshore Simulation Test Setup for Temperature and Strain Sensing of Submarine Cable based on BOTDA

Xiaowei Huang Kai Yao Guanshu Sun Jing Zhou Yikang Chen

The 500kV submarine cable route of Hainan Networking System starts from Nanling Village, Jiaowei Township, Xuwen County, Zhanjiang City, Guangdong Province. It crosses the Qiongzhou Strait to Linshi Village, Qiaotou Town, Chengmai County, Hainan Province. Hainan Networking System 500kV AC Submarine Cable is the first ultra-high voltage, large capacity and long-distance cross-sea networking power cable in China. It is 31 km. In this article, there are three main parts. The first part introduces the status of submarine cable monitoring and the BOTDA test principle. The second part is to design a calibration experiment to calibrate the Brillouin temperature coefficient and the Brillouin strain coefficient for the test fiber of the submarine cable. The third part is to design the spatial distribution rate verification experiment of Brillouin optical time domain reflectometry analyzer to ensure the error of equipment and experiment, so that it can be applied in submarine cable in the future.

Design and implementation of a Movement Progressive Induced Training method for robot-assisted upper limb rehabilitation

Chinese Control Conference (2013)

Zhu Baotong Yaping Dai Qiang Guo

This paper proposed a Movement Progressive Induced Training (MPIT) method, which is used for robot-assisted upper limb rehabilitation. This method produced a whole working plane regular progressive inducement. Under this progressive inducement, training movement is compatible with the patient by changing its task automatically, which maintains a high level of patient involvement and enhances motivation of movement throughout the whole process of training. Particularly, MPIT method provided theoretical and practical bases for upper limb hemiplegia treatment from a novel aspect of progressive inducement. Simulations and preliminary experiment evaluations indicated that the MPIT method is capable of treating hemiplegia patients and of good effectiveness.

Maximizing Energy Storage of Flexible Aqueous Batteries through Decoupling Charge Carriers

Advanced Energy Materials (2021)

Chunlong Dai Xuting Jin Hongyun Ma Linyu Hu Guoqiang Sun

Abstract Flexible aqueous rechargeable batteries that integrate excellent mechanical flexibility and reliable safety hold a great promise for next‐generation wearable electronics. Unfortunately, currently available options are unsatisfactory due to their low specific capacity, limited energy density, and unstable voltage output. Herein, to overcome these challenges, high theoretical specific capacity zinc and sulfur as the anode and cathode are selected, respectively. Furthermore, a strategy is proposed, that decoupling charge carriers in anolyte and catholyte to simultaneously endow the zinc anode and sulfur cathode with optimal redox chemistry, maximizes the energy storage of flexible aqueous batteries. The new zinc–sulfur hybrid battery possesses merits of ultrahigh theoretical specific capacity (3350 mAh g S −1 ) and volumetric energy density (3868 Wh L −1 ), low cost, ecofriendliness, and ease of fabrication and is a promising next‐generation aqueous energy storage system. The fabricated flexible aqueous zinc–sulfur hybrid battery delivers a stable output voltage (release 92% of its full capacity within a small voltage drop of 0.15 V) and an ultrahigh reversible capacity of 2063 mAh g S −1 at 100 mA g S −1 , thus setting a new benchmark for flexible aqueous batteries and is promising to play a part in future flexible electronics.
