Photodegradation of organophosphorus pesticides in honey medium

Highlights•Photodegradation experiments of three different OPs in honey medium were conducted.•Three different irradiation intensities were used for experiments.•Coumaphos showed the highest degradability.•Three OPs showed the minimum residual percentages under 750 W/m2 sunlight irradiation.

Factors associated with the age of natural menopause and menopausal symptoms in Chinese women

AbstractObjectiveTo investigate the factors associated with the age of natural menopause and menopausal symptoms in a large population of Chinese middle-aged women.Study designIn this cross-sectional study, a total of 20,275 women (40–65 years) attending health screening in Jiangsu Province of China were enrolled. A structured questionnaire was used to collect data of demographics, menopausal status, chronic diseases, reproductive history, etc. Also we evaluated the severity of menopausal symptoms by Kupperman menopause index (KMI).Main outcome measureMenopausal age and scorings of Kupperman menopause index.ResultsThe overall median age at natural menopause was 50 years. Lower educational level, poor economic status, lower body mass index (BMI), age at menarche less than 14 years, nulliparity and smoking were associated with earlier onset of natural menopause (P < 0.05). The most frequently symptoms in postmenopausal women were sexual problems (57.05%), muscle/joint pain (53.29%) and insomnia (51.02%), while fatigue, insomnia and muscle/joint pain were predominant symptoms in pre- and peri-menopausal women. After adjusting for confounding factors, logistic regression analysis revealed that women with poor educational background, low income, divorce, higher BMI, higher parity, smoking and chronic diseases presented higher KMI scores (P < 0.05).ConclusionThe study provided an estimate of median age at natural menopause in Chinese women. The main factors contributing to earlier onset of menopause and severity of menopausal symptoms were lower educational level, poor economic status, and smoking. Thus, this study provides important insights for physicians to prevent and treat menopause related symptoms.

Enhanced photovoltaic performance of dye-sensitized solar cells based on Co9S8 nanotube array counter electrode and TiO2/g-C3N4 heterostructure nanosheet photoanode

Highlights•g-C3N4 modified TiO2 nanosheets as photoanodes and Co9S8 nanotube arrays as counter electrodes.•g-C3N4 modified TiO2 nanosheets effectively restrains the recombination rate of photogenerated charges.•Co9S8 nanotube arrays CEs show higher electrocatalytic ability towards I−/I3− reaction than Pt CE.

Modifying lewis base on TiO2 nanosheets for enhancing CO2 adsorption and the separation of photogenerated charge carriers

Highlights•TiO2/[WO4]2− composites were prepared via in-situ ion exchange strategy for the first time.•[WO4]2− as a lewis base was used to improve the CO2 adsorption.•[WO4]2− as a lewis base was used to promote the carriers’ separation.•TiO2/[WO4]2− significantly improved the CO yield compared to that of pristine TiO2.

Enhanced photocatalytic CO2 reduction via the synergistic effect between Ag and activated carbon in TiO2/AC-Ag ternary composite

Highlights•The preparation approach for TiO2/AC-5-Ag composites photocatalysts is convenient.•TiO2/AC-5-Ag shows a large specific surface area and wider light absorption.•TiO2/AC-5-Ag exhibits much higher CO2 adsorption capacity than pristine TiO2.•The CO2 photo-reduction efficiency of TiO2/AC-5-Ag is better compared to that of TiO2.
