Abstract As an important agricultural waste, corn cob is one of the most abundant lignocellulosic biomass. In this work, dilute acid pretreatment using seven different organic acids were compared for compositional analysis of corn cob. The first pKa of organic acids, influenced by the number and type of the side group and distance between two carboxylic groups, played a crucial role in the pretreatment effect. Citric acid was found to have better pretreatment performance than other tested dicarboxylic acids. Under the condition of 30 mM, 160°C and 60 min, the level of xylose reached 22.64 g/L More >

Abstract Based on social cognitive career theory, this study examined career success criteria clarity and career decision-making self-efficacy as mediators in the relationship between career exploration and affective well-being. Data were collected from 475 emerging adults in their early career stages in China. The results showed that both career success criteria clarity and career decision-making self-efficacy mediated the relationship between career exploration and affective well-being. Career decision-making self-efficacy exhibited a stronger mediating effect on this relationship than career success criteria clarity. These findings reveal some important mechanisms underlying the role of career exploration in generating affective More >

Abstract Based on basic psychological needs theory of self-determination theory, this study investigates the interaction effect of proactive personality and career exploration on well-being for graduating students during school-to-work transition. Using a survey sample of 216 graduating students in China, we found that: 1) Proactive personality had a positive relationship with well-being. 2) Career decision-making self-efficacy mediated the relationship between proactive personality and well-being. 3) Career exploration negatively moderated the relationship between proactive personality and career decision-making selfefficacy. The relationship between proactive personality and career decisionmaking self-efficacy was stronger when career exploration was lower. 4) Career More >

Abstract Based on the embedded atom method (EAM) and molecular dynamics (MD) method, in this paper, the tensile deformation properties of Cu nanowires (NWs) with different pre-existing defects, including single surface defects, surface bi-defects and single internal defects, are systematically studied. In-depth deformation mechanisms of NWs with pre-existing defects are also explored. It is found that Young's modulus is insensitive to different pre-existing defects, but yield strength shows an obvious decrease. Defects are observed influencing greatly on NWs' tensile deformation mechanisms, and playing a role of dislocation sources. Besides of the traditional deformation process dominated by More >
