The separation efficiency of charge carriers determines the analytical sensitivity of the paper-based photoelectrochemical sensor. Herein, the Lewis base modification strategy is proposed to promote the carrier separation through an in-situ ion exchange method. Firstly, three-dimensional paper-based hierarchically TiO2 (PHT) arrays are prepared with the one-step hydrothermal method. With the aid of Lewis base, the photoinduced charge separation efficiency and the photocurrent signal are obviously increased. Ultimately, sensitive sensing of prostate specific antigen (PSA) is achieved and the linear range is 1 pg/mL-100 ng/mL with the detection limitation of 0.3 pg/mL. [ABSTRACT FROM AUTHOR]

The objective of this paper is to clarify the influence of job characteristics on promotive voice. Based on the reviews of relevant research, this paper proposes that the theoretical hypothesis that various dimensions of job characteristics are positively related to promotive voice. In order to test the hypothesis, the questionnaires were designed on the basis of widely accepted mature scales to carry out paired questionnaire survey of superiors and subordinates by stratified sampling according to different types of job positions in 24 enterprises. 437 sets of data were collected and then analyzed by the statistic software SPSS to verify the hypothesis. As a result, the survey data supported the hypothesis of positive correlation between different dimensions of job characteristics and promotive voice. Therefore, this paper proposes to improve job characteristics to enhance promotive voice for organizations. [ABSTRACT FROM AUTHOR]
