    • The mining industry safety production situation is becoming more and more severe in China with safety accidents occurring frequently, which is closely related to insufficient safety investments and unreasonable distribution. Additionally, it does not keep in line with the main purpose of occupation health and safety management system (OHSAS18001).In order to carry on the reasonable scientific disposition to the safety investments of the mining industry, increase safety investments efficiency and satisfy the requirements of OHSAS18001, data envelopment analysis (DEA) is adopted to calculate the safety investments, loss and output. Firstly, the analysis software MYDEA of DEA is used to calculate the results to obtain the evaluation result of safety benefits. Secondly, the target value of the improvement work in the aspect of investment is achieved by method of projection analysis when the decision making unit (DMUj0) of non DEA efficiency is changed into DEA efficiency. Lastly, it can be obtained on the basis of grey relational analysis (GM) that the investment amount of safety management and training of employees has the highest relation on the effective safety benefits of the mining industry. Thus, the investment of safety management and training of employees should be strengthened. This kind of empirical method of comprehensive model provides a direction and theoretical reference for safety investments benefits analysis and optimized investment structure, and a structure for the effective operation of mining industry occupational health and safety management system

  • Direct measurement and modulation of single-molecule coordinative bonding forces in a transition metal complex
  • 2013
  • Ingår i: Nature Communications. - 2041-1723. ; 4
  • Tidskriftsartikel (refereegranskat)abstract
    • Coordination chemistry has been a consistently active branch of chemistry since Werner’s seminal theory of coordination compounds inaugurated in 1893, with the central focus on transition metal complexes. However, control and measurement of metal–ligand interactions at the single-molecule level remain a daunting challenge. Here we demonstrate an interdisciplinary and systematic approach that enables measurement and modulation of the coordinative bonding forces in a transition metal complex. Terpyridine is derived with a thiol linker, facilitating covalent attachment of this ligand on both gold substrate surfaces and gold-coated atomic force microscopy tips. The coordination and bond breaking between terpyridine and osmium are followed in situ by electrochemically controlled atomic force microscopy at the single-molecule level. The redox state of the central metal atom is found to have a significant impact on the metal–ligand interactions. The present approach represents a major advancement in unravelling the nature of metal–ligand interactions and could have broad implications in coordination chemistry.

    • In order to effectively analyze, control, and prevent occupational health risk and ensure the reliability of the weight, a method based on FMEA (failure mode and effects analysis) and an improved AHP (analytic hierarchy process) model was established. The occupational disease of the occupational health and safety management system (OHSAS18001) of the mining industry in the southwest of Hubei Province is taken as an example, the three most significant risk factors (dust, noise, and gas) are selected as the research objects, the FMEA method is used, an expert questionnaire is carried out to establish the comprehensive assessment matrix of each indicator according to the RPN (risk priority number) value, and, finally, a case study is conducted through the FMEA and the improved AHP model The results show that the occupational disease of the mining industry's occupational health and safety management system belongs to a "general" grade, which is in line with the physical examination results of the Center for Disease Control and Prevention of Ezhou City in 2015. The improved AHP and FMEA comprehensive assessment model of occupational disease is proved feasible. This method can be incorporated in the process management of the enterprise for the purpose of occupational disease prevention in advance and continuous improvement on the occupational health and safety of employees. Additionally, the area research on this integrated model should be optimized continually in actual situations.

  • Application of Statistical Methods on Occupational Health and Safety Management in the Mining Industry in Ezhou City, China
  • 2018
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • Chinaʹs mining enterprises are confronted with insufficient safety investments, insufficientsafety benefits, recurrent occupational diseases and accidents, low level of safety riskmanagement, and many employee complaints, that seriously affect the economicdevelopment and the sustainable development of the country. Selection of scientific, accurateand comprehensive evaluation methods of all aspects of occupational health and safetymanagement will directly affect the evaluation results and then the direction of improvement;which is greatly needed.The aim of this thesis is twofold: one aim is to test and analyze a set of evaluationmethods that provide different perspectives on how occupational health and safetymanagement really works in the mining industry in Ezhou City, China. The other aim is toexplore a set of comprehensive evaluation methods that are suitable for occupational healthand safety management in the industries as a whole.This thesis is based on the theory of Multi Objective Decision Making and Grey System,and is broken down into three phases including: The first phase of my study: to describe the applications of the methods in five aspects ofoccupational health and safety in the mining industry in Ezhou City, China. This isshown in five articles and Chapter 1‐5. The second phase: to present some suggestions of improvements for the development ofthe occupational health and safety in the mining industry in Ezhou City, China. This ispresented in Chapter 6 in my study. The third phase: to explore a set of comprehensive evaluation methods that are suitablefor the occupational health and safety management in the industries. This is also shownin Chapter 6 in my study.In this thesis I mainly used six methods to evaluate occupational health and safetymanagement and the suitability of them for this type of research as well as in other types inindustrial activity. The six methods included in my research are: entropy weight(EW), failuremode and effect analysis (FMEA), improved analytic hierarchy process (AHP), dataenvelopment analysis (DEA), grey relational analysis (GRA) and 2‐tuple linguisticinformation (2‐TLI). The results of the analysis showed that: EW can be well used to evaluate the multi indicators of occupational health and safetymanagement, and can be extended to other areas such as safety management evaluation,the quality of the project, project forecasting and other industrial activities; FMEA has been proved practical, simple and less costly in the perspective of riskmanagement, occupational health and safety management, identification and control ofenvironmental factors in enterprises, and quality key point preventive control in allindustrial activities; Improved AHP is practical, simple and less costly for multi objective and multi criteriadecision making problems in all industrial activities; DEA is special for production efficiency and can well estimate the effective productionfrontier by calculating the history data of the financial department, and embodies itsunique advantages in dealing with multi indicator inputs and multi indicator outputs inall industrial activities; GRA does not require too much sample size and any typical distribution regulation; thecalculated amount of data is relatively small, and the results would always be in goodagreement with the qualitative analysis, so it is quite suitable for measuring the degree ofassociation between factors for indicator evaluation according to their similarity ordissimilarity. GRA can cope with the types of problem associated with comparisonbetween evaluation objects and the comparison object in all industrial activities; 2‐TLI is special for language information and can provide the basis for multi‐attributedecision analysis in spite of large amounts of calculation in all industrial activities.On the whole, each method has its advantages and disadvantages, and the key to judgingwhether a method is most suitable is if it can withstand the validation of practice. Anyhow,the main contribution of this research is that it has systematically tested and verified a set ofstatistical methods applied in a mining industry in Ezhou, China, and explored a set ofstatistical methods utilized in occupational health and safety management in industrialactivities. Additionally, another contribution of this research is that it has provided a directionfor improvement of sustainable development.

    • The sustainable development of mining occupational health and safety management system is inseparable from its internal and external environment. Through IFE and EFE matrix models, the key internal and external factors affecting the sustainable development of some mining in the Southwest of the Hubei Province are analyzed. Then entropy method is adopted to determine the weight of each key factor. According to the weighted total score ranking, the most important internal and external key factors affecting China's sustainable development include the following: not enough detailed degree of hazard identification, not enough safety awareness, lack of contingency plans to assess the timely exercise, not enough deep mining of internal audit, impact of relevant laws and regulations on enterprises, impact of the interested parties on the changing requirements of the enterprise, risk management brought by interested parties, risk management of product life cycle, and changes in the market environment for enterprises to put forward new requirements. In this paper, combined with OHSAS18001 operation condition of the mining in the Southwest of Hubei Province, seven suggestions for improvement are put forward which provide valuable reference for the sustainable development of mining OHSAS18001.

  • Copper-coordinating polymers for marine anti-fouling coatings: A physicochemical and electrochemical study of ternary system of copper, PMMA and poly(TBTA)
  • 2016
  • Ingår i: Progress in Organic Coatings. - 0300-9440. ; 97, s. 216-221
  • Tidskriftsartikel (refereegranskat)abstract
    • Biofouling is a general problem in marine applications. Copper has been used as an anti-biofouling agent in marine coatings for decades; however, its widespread use has resulted in regulatory restrictions due to high copper concentrations in harbors and areas with limited water circulation. Here we present a new approach for anti-fouling coatings using microparticles of poly(tris[(benzyltriazol)methyl]amine) (poly(TBTA)) polymers to absorb and control the interaction between a surface coating and the copper naturally present in seawater with the intention of creating a flux of copper across the water/coating interface. The preparation and characterization of microparticles of poly(TBTA) as well as hybrid PMMA: poly(TBTA) has been described to study the feasibility of tuning the copper-coordination properties of a generic marine coating using these paint-compatible microparticles. The properties of microparticles of poly(TBTA), PMMA and the PMMA: poly(TBTA) hybrid were therefore studied using cyclic voltammetry and NMR spectroscopy. It is demonstrated that the copper ions interact specifically with microparticles containing the coordinating polymer poly(TBTA) and that these microparticles have a high absorption capacity of more than 5 wt% for copper.

  • Construction of Insulin 18-mer Nanoassemblies Driven by Coordination to Iron(II) and Zinc(II) Ions at Distinct Sites.
  • 2016
  • Ingår i: Angewandte Chemie (International edition). - : John Wiley and Sons Inc.. - 1521-3773. ; 55:7, s. 2378-2381

    • Controlled self-assembly (SA) of proteins offers the possibility to tune their properties or to create new materials. Herein, we present the synthesis of a modified human insulin (HI) with two distinct metal-ion binding sites, one native, the other abiotic, enabling hierarchical SA through coordination with two different metal ions. Selective attachment of an abiotic 2,2'-bipyridine (bipy) ligand to HI, yielding HI-bipy, enabled Zn(II) -binding hexamers to SA into trimers of hexamers, [[HI-bipy]6 ]3 , driven by octahedral coordination to a Fe(II) ion. The structures were studied in solution by small-angle X-ray scattering and on surfaces with AFM. The abiotic metal ligand had a higher affinity for Fe(II) than Zn(II) ions, enabling control of the hexamer formation with Zn(II) and the formation of trimers of hexamers with Fe(II) ions. This precise control of protein SA to give oligomers of oligomers provides nanoscale structures with potential applications in nanomedicine.
