Electric double layer-mediated polarization field for optimizing photogenerated carrier dynamics and thermodynamics.

Photocatalytic hydrogen evolution efficiency is limited due to unfavorable carrier dynamics and thermodynamic performance. Here, we propose to introduce electronegative molecules to build an electric double layer (EDL) to generate a polarization field instead of the traditional built-in electric field to improve carrier dynamics, and optimize the thermodynamics by regulating the chemical coordination of surface atoms. Based on theoretical simulation, we designed CuNi@EDL and applied it as the cocatalyst of semiconductor photocatalysts, finally achieved a hydrogen evolution rate of 249.

The psychometric properties of positive and negative beliefs about the rumination scale in Chinese undergraduates.

Background: Rumination, a transdiagnostic factor in different psychopathological conditions, is believed to be activated and sustained by dysfunctional metacognition. The Positive Beliefs about Rumination Scale (PBRS) and the Negative Beliefs about Rumination Scale (NBRS) have been used to measure the metacognitive beliefs of rumination and have been investigated in many cultural contexts. However, it remains unclear whether these scales can work as well for the Chinese population.

Should we abandon annual physical examination? - A meta-analysis of annual physical examination and all-cause mortality in adults based on observational studies.

Several meta-analyses based on randomized clinical trials data have failed to find an association between the annual physical examination (APE) and reduced mortality; however, no comparable meta-analysis based on observational data exists. We conducted a meta-analysis of observational studies comparing APE versus non-APE in adults for all-cause mortality. English-language searches of four databases (PubMed, CINAHL, EMBASE, and Google Scholar) between the years 2000 to 2019 yielded seven observational studies that investigated APE versus non-APE in healthy adults in relation to all-cause mortality.

This study aims to examine behavioral and cognitive problems of risky decision among Chinese young people aged 15-25 years. The balloon analogue risk task (BART) and event-related potential (ERP) were combine used to explore the neural mechanism of risky decision process whether infected by impulsivity trait.

'Mindfulness Living with Insomnia': an mHealth intervention for individuals with insomnia in China: a study protocol of a randomised controlled trial.

Introduction: Insomnia has a remarkably negative effect on the work, quality of life and psychosomatic health of individuals, and imposes a substantial economic burden on society. Mindfulness-based interventions (MBIs) have proven beneficial in the treatment of insomnia. However, the effect of mobile or online-based (mHealth) MBIs requires further verification.

Electrolyte Additives for Improving the High-Temperature Storage Performance of Li-Ion Battery NCM523∥Graphite with Overcharge Protection.

The overcharge safety performance of lithium-ion batteries has been the major bottleneck in the widespread deployment of this promising technology. Pushing the limitations further may jeopardize cell safety when it is performed at high-temperature storage. On the basis of the lacking systematic research on overcharge protection electrolyte additives with high-temperature storage capacity, we explore the promotion effect of overcharge additives on electrolyte decomposition at 60 °C.

Dihydroartemisinin represses oral squamous cell carcinoma progression through downregulating mitochondrial calcium uniporter.

Dysregulation of mitochondrial calcium uniporter (MCU) exerts a carcinogenic effect in several cancers. Nevertheless, the roles of MCU in oral squamous cell carcinoma (OSCC) remain elusive. It has been reported that dihydroartemisinin (DHA) may suppress the progression of OSCC but its associated mechanisms have not been investigated.

Strategy to Enhance the Cycling Stability of the Metallic Lithium Anode in Li-Metal Batteries.

Based on the analysis of systematic research (density functional theory calculations, physical characterizations, and electrochemical performances), here, we report a novel mixture surface modification layer of LiC&LiF, which can enhance the lithium-ion diffusion and decrease the local current density. This is beneficial to the improvement of cycling stability. As a result, the Li@LiC&LiF-5/NCM half-cell possesses an excellent capacity retention of 94% after 100 cycles at 0.

Psychometric Properties of the Chinese Version of the Intolerance of Uncertainty Inventory in Chinese College Students.

Effects of short-term mindfulness-based training on executive function: Divergent but promising.

Mindfulness-based training (MBT) has repeatedly been proven effective in improving mental health, as well as in eliciting advantages in executive functions (EFs), as demonstrated by objective measures. However, few studies have discussed the role MBT plays in increasing EFs over short periods of time. This current review, to our knowledge, is the first study to investigate the effect of short-term MBT on EFs.

What Do You Think About Your Dreams? The Construction of a Belief About Dreams Questionnaire.

Background And Purpose: Nightmare distress (ND) is associated with a broad spectrum of psychopathological conditions such as anxiety, depression and bipolar disorder. Some studies have indicated that dream beliefs play an important role in the occurrence and treatment of nightmare distress. However, existing instruments used to assess dream beliefs either fail to satisfy the requirements of the psychometrics or fail to capture the essence of dream beliefs.

Validation of the Chinese version of the Health Cognitions Questionnaire in Chinese college students.

Purpose: The cognitive behavioral model is considered the most comprehensive for explaining the pathogenesis of health anxiety (HA). The model proposes 4 dysfunctional beliefs that play a vital role in developing and sustaining HA: a) the likelihood of contracting or having an illness, b) awfulness of the illness, c) difficulty coping with illness, and d) inadequacy of medical services. The Health Cognitions Questionnaire (HCQ), widely used in English populations, was developed for assessing these core cognitions.

Efficacy of mindfulness-based intervention ('mindfulness-based joyful sleep') in young and middle-aged individuals with insomnia using a biomarker of inflammatory responses: a prospective protocol of a randomised controlled trial in China.

Introduction: Insomnia is a prevalent and significant public health concern. Insomnia can lead to increased inflammatory markers associated with chronic diseases such as cardiovascular disease, diabetes and cancer. Studies suggest that mindfulness-based interventions (MBIs) are more easily delivered within the community than cognitive behavioural therapy for insomnia (CBT-I) which was recommended as the preferred non-pharmacological treatment by the American Academy of Sleep Medicine, are effective in insomnia treatment and can reduce inflammatory markers level in older individuals with insomnia.

[Establishment of the theory and operation of willing acceptance and commitment therapy].

Mindfulness-based psychotherapy, known as the third-wave cognitive behavior therapy, showed a multi-cultural integration trend. As part of it, willing acceptance and commitment therapy not only took root in the discoveries in the fields of evolutionary psychology and cognitive psychology, but also absorbed the concepts of psychotherapy from Chinese traditional culture. As a result, it regards truth and harmony as the essence of health, proposes a triangle model (health/pain-willing acceptance-striving) to elucidate the mechanism of psychopathology and psychotherapy in theory.
