Family Socio-Economic Status and Children's Play Behaviors: The Mediating Role of Home Environment.

Family socio-economic status (SES) is a significant predictor of children's early learning performance, while little is known about the relationship between family SES and children's play. This study aimed to examine how family SES was related to different aspects of children's play behaviors and whether the home environment served as a mediator in this relationship. A total of 844 mothers of children aged three to six ( = 431) from different SES backgrounds ( = 123, = 322, = 399) reported the situation of the home environment and their children's play behaviors with self-developed questionnaires.

Mimicking Thylakoid Membrane with Chlorophyll/TiO/Lipid Co-Assembly for Light-Harvesting and Oxygen Releasing.

There is a growing interest in the design and construction of artificial photosythetic materials for solar energy utilization and conversion. Inspired by the structure of thylakoid membrane, we present here a hybrid construct for light-harvesting and oxygen releasing. Our design conjugates chlorophyll to TiO in a native-like membrane environment.

Investigation of the potential risk of coal fire to local environment: A case study of Daquanhu coal fire, Xinjiang region, China.

Underground coal fires are disasters associated with coal mining activities. This study, attempts to investigate the impact of coal fires on the soil and atmosphere by measuring heavy metal concentration and borehole gas emissions for the Daquanhu coal fire zone. Different methods and equipment were used in this study, such as remote sensing, determination of the surface temperature and vegetation, field meteorological surveys, air/smoke analysis, flame photometry, atomic absorption spectrophotometry, atomic fluorescence spectrophotometry, and alkali diffusion.
