Ce Decoration-Enhanced Singlet Oxygen Generation of Titanium-Oxide Clusters for Photocatalytic Oxidation of Aromatic Alcohols.

In photocatalysis, the nature of reactive oxygen species plays a pivotal role in determining product selectivity. Yet, selective generation of singlet oxygen (O) is particularly desirable for achieving targeted photooxidations. Herein, two new nanosized titanium-oxide clusters (TOCs) doped with Ce, TiCe and TiCe, were synthesized and explored in the selective photocatalytic oxidation of benzyl alcohols to benzaldehydes under mild conditions.

P62 acts as an intermediator in cadmium-induced osteocyte apoptosis and osteoporosis in mice.

Cadmium (Cd) is a pervasive environmental pollutant. The skeletal system is particularly susceptible and Cd exposure linked to the development of osteoporosis. Intracellular p62 is closely related to bone remodeling and bone marrow integrity.

Electronic State Modulation of a Single-Cu Site on a Bimetallically Doped Titanium-Oxo Cluster to Enhance CO Storage.

While atomically monodisperse nanostructured materials with controllable heterometal dopants are highly desirable to unravel the structure-catalysis relationships, their controlled synthesis and atomic-level structural determination remain significant challenges. Here, we report on nanosized titanium-oxo clusters featuring two heterometallic sites, TiMOSal(HSal)(OCH)(CHOH) (denoted as TiM; M = MnCu, CaCu, Cu, Mn, Ca; Sal and HSal represent salicylate and 2-hydroxybenzoate, respectively), which were used for catalyzing and photocatalyzing the CO/epoxide cycloaddition to synthesize cyclic carbonates. Notably, the valence state of Cu is modulated by Mn in the TiMnCu cluster as Cu exists in the δ+ valence (1 < δ < 2), whereas in TiCu and TiCaCu, Cu is + 2 valence.

Examining the Relationship Between Internet Use and Depressive Symptoms Among Older Adults: Analyses of Mediators and Moderators.

Objectives: The study aimed to investigate the influence mechanism underlying the relationship between Internet use and depressive symptoms in Chinese older adults.

Methods: Data were derived from the 2018 wave of China Longitudinal Aging Social Survey. Mediation and moderation analyses were conducted using Ordinary list squares (OLS) regression analysis.

The responding mechanism of indigenous bacteria in municipal wastewater inoculated with different concentrations of exogenous microalgae.

Indigenous bacteria popularly exist in real wastewater. Therefore, the potential interaction between bacteria and microalgae is inevitable in microalgae-based wastewater treatment systems. It is likely to affect the performance of systems.

Exposure, perceived risk, and psychological distress among general population during the COVID-19 lockdown in Wuhan, China.

Introduction: The COVID-19 pandemic that has been going on since the end of 2019 impacts people on both the physical and psychological levels. However, the psychological status, especially its underlying psychosocial mechanisms among the general population in Wuhan, the earliest epicenter and hardest-hit city in China during the pandemic, has not been well investigated. This study aimed to examine the relationships between exposures, perceived risk, and psychological distress among the general population in Wuhan during the COVID-19 lockdown.

Who would rescue the dilemma of Chinese elderly care? An evolutionary game analysis and simulation research on the formalization of the domestic service industry with subsidy policy.

Since China entered the aging society, the surging demand for elderly care and the industrial upgrading of "silver economy" has forced the domestic service industry to face endogenous challenges. Among them, the formalization of the domestic service industry can effectively reduce the transaction costs and risks of actors, innovate the endogenous vitality of the industry, and promote the improvement of elderly care quality through a triangular employment relationship. By constructing a tripartite asymmetric evolutionary game model of clients, domestic enterprises and governmental departments, this study uses the stability theorem of differential equations to explore the influencing factors and action paths of the system's evolutionary stable strategies (ESS), and uses the research data collected from China to assign values to models for simulation analysis.

Amelioration and deterioration: Social network typologies and mental health among female domestic workers in China.

Previous quantitative studies on the effects of social network types on mental health have obtained inconsistent or conflicting results, due to problems such as sample selection bias or crude measurement of variables. In this study, we avoided these problems by using appropriate statistical methodology to examine the effect of various forms of social network on the mental health of a sample of 987 Chinese female domestic workers. Thus, we measured social network types in terms of both network attributes (friend networks and family networks) and interaction channels (face-to-face, telephone, and WeChat/QQ channels, where the latter are two popular online messaging platforms in China), and used the coarsened exact matching method to obtain a balanced sample.

The Influence of Person-Job Fit on Health Status and Depression Among Chinese Domestic Workers: Mediating Effect of the Employer-Employee Relationship.

Domestic workers usually perform manual work in households. Unlike fixed work, their work tends to be individualized and atomized. Their person-job fit and relationship with employers might exert some influence on their health, both physical and psychological.

Examining the impact of functional disability and cognitive impairment on mental health of Chinese elderly.

Depression and anxiety, as the two most prevalent psychiatric disorders, pose a huge challenge to the quality of life of the elderly. Using a sample of 7,721 elderly from the latest Chinese Longitudinal Health and Longevity Survey (CLHLS), the present study intended to explore the association between mental health and socioeconomic status, physical functional disability, and cognitive impairment among Chinese elderly by adopting multivariate logistic regression analyses. The results revealed that depression, anxiety, and their comorbidity are significantly higher in the elderly with instrumental activities of daily living (IADL) disability, cognitive impairment, financial strain, and living alone.

Act Tough and Soft: Video Monitoring, Hongbao Gifts, and the Job Satisfaction of Domestic Workers.

There is a rapidly growing demand for domestic services among urban families in China. However, domestic work remains a low-status occupation with a high turnover rate. Focusing on the job satisfaction of domestic workers is useful to interpret this phenomenon.

Occupational Characteristics in the Outbreak of the COVID-19 Delta Variant in Nanjing, China: Rethinking the Occupational Health and Safety Vulnerability of Essential Workers.

The risk of contracting COVID-19 varies by occupation. Clarifying the occupational disparity in the infection risk is crucial to the prevention and control of the epidemic in the workplace. In late July, some new cases of COVID-19 were confirmed among cleaners working in Lukou International Airport in Nanjing, China.

Prediction of Epidemic Spread of the 2019 Novel Coronavirus Driven by Spring Festival Transportation in China: A Population-Based Study.

After the 2019 novel coronavirus (2019-nCoV) outbreak, we estimated the distribution and scale of more than 5 million migrants residing in Wuhan after they returned to their hometown communities in Hubei Province or other provinces at the end of 2019 by using the data from the 2013-2018 China Migrants Dynamic Survey (CMDS). We found that the distribution of Wuhan's migrants is centred in Hubei Province (approximately 75%) at a provincial level, gradually decreasing in the surrounding provinces in layers, with obvious spatial characteristics of circle layers and echelons. The scale of Wuhan's migrants, whose origins in Hubei Province give rise to a gradient reduction from east to west within the province, and account for 66% of Wuhan's total migrants, are from the surrounding prefectural-level cities of Wuhan.
