Cellulose micro-fibrils (CMF), which are green, sustainable and are made from abundant renewable biomass, have attracted much attention in the research community for various applications. In this study, we presented a novel magnetic cellulose composite catalyst (HKUST-1/Fe3O4/CMF) for pollution remedy purpose. The main function of CMF is to improve the dispersion of metal organic framework (MOF) crystals...
The characteristics of performance degradation data are analyzed. The disciplinarians of numerical control machine tool performance degradation data with time are analyzed, the reliability assessment methods with performance degradation data based on performance degradation distribution is presented. The performance gradation data contain abundant numerical control machine tool reliability information,...
The reliability of numerical control machine tool is one of the key problems to restrict the rapid development of numerical control machine too industry. Based on traditional reliability analysis methods, the degradation failure modes of numerical control system are investigated, the reliability modeling analysis method based on competing mode of hard and soft failure is presented. The relations between...
