Efficient photocatalysts play an important role in the various fields such as pollutant treatment and the generation of clean energy. Therefore, developing a photocatalyst with high activity is of great significance. Herein, scandium‐based fluorescent microspheres (Sc‐FMs) are facilely prepared through the one‐pot hydrothermal polymerization of scandium ions and tartaric acid. The prepared Sc‐FMs show strong blue solid‐state fluorescence, with a maximum emission at 412 nm. Meanwhile, Sc‐FMs possess a strong white‐light photocatalysis ability, which can be used for the photodegradation of dye pollutants (rhodamine 6 G) under low power white light without the assistance of any radical generating agents. In addition, the Sc‐FMs display good stability and recyclability. As a result, this new and efficient Sc‐FMs photocatalysts hold a promise for potential applications in environmental treatment.

To examine whether parents' cultural values are related to parenting practices and children's behavioural adjustment, mothers, fathers and children (N = 218) from two cities in China (Jinan and Shanghai) were interviewed when children were, on average, 10 years old. Mothers and fathers reported their endorsement of cultural values (individualism, collectivism, conformity), which were used to separately predict warmth and family obligation expectations reported by each parent, as well as children's report of parental psychological control, rule setting, knowledge solicitation and perceived family obligation expectations. Cross‐informant (parents and child) composites of internalising and externalising behaviours were also obtained. The results showed that maternal individualism positively predicted parents' knowledge solicitation. Parental collectivism positively predicted their own warmth and family obligation expectations. Mothers' conformity positively predicted mothers' family obligation expectations, paternal warmth and children's perception of family obligation, whereas fathers' conformity only positively predicted fathers' family obligation expectations. These effects were largely consistent across regional subsamples, although mothers in Jinan were more collectivistic than mothers in Shanghai, and parents in Shanghai adopted less psychological control and more knowledge solicitation in parenting.

Adolescents' family obligation is a cultural strength that shows enduring prevalence in China. Given that the meaning of family obligation has undergone rapid changes in recent decades, it is crucial to examine the role of family obligation in adolescent adjustment in contemporary China. More importantly, although past research has investigated the consequences of family obligation on adolescents' adjustment, little is known about the antecedents of Chinese adolescents' family obligation. Using a two‐wave longitudinal sample of 450 Chinese adolescents (mean age = 13.78 years, SD =.71 years; 49% female) and their parents, the current research explored two questions. First, this study examined the role of family obligation in adolescents' academic achievement, externalizing problems, and internalizing problems over early adolescence. Second, this study explored the role of parents in predicting Chinese adolescents' family obligation, specifically whether parental expectations or parental acceptance was predictive of adolescents' family obligation over time. Third, this study investigated whether family obligation is an underlying mechanism between parenting and Chinese adolescents' adjustment. Results showed that Chinese adolescents' family obligation was longitudinally associated with increased academic achievement and reduced externalizing problems. Moreover, perceived parental acceptance, but not parental expectations, was longitudinally associated with Chinese adolescents' greater family obligation. Notably, family obligation mediated the longitudinal effect of parental acceptance on Chinese adolescents' externalizing problems. By studying both the consequences and antecedents of Chinese adolescents' family obligation, this study helps provide a comprehensive understanding of this cultural strength. [ABSTRACT FROM AUTHOR]

Numerous synaptic devices have been explored for the next generation of energy‐efficient computing techniques. Among them, optoelectronic synaptic devices based on semiconductor/ferroelectric heterostructures have received a lot of attention lately due to their amazing parallelism, efficiency, and fault tolerance properties. However, polarizing the ferroelectric layer or gating the dielectric layer is necessary to achieve tunable synaptic functions, which generally causes an increase in energy consumption and complex manufacturing processes. Here, a simple and efficient method is demonstrated to develop a tunable optoelectronic synaptic device based on a single ferroelectric semiconductor, BiFeO3‐BaTiO3 (BF‐BT). Multi‐essential synaptic functions including short‐term plasticity, paired‐pulse facilitation, and long‐term plasticity are all satisfactorily replicated by the memristor device. More significantly, light‐controllable synaptic behaviors are realized by altering the ferroelectric polarization state of BF‐BT. Synaptic devices' relaxation characteristics enable simulation of the effects of positive/negative emotions on learning and forgetting processes. This study highlights the potential of the ferroelectric semiconductor memristor in constructing the efficient optoelectronic synapses for future neuromorphic electronics with the ability to learn and sense optical information.

Artificially performing chemical reactions in living biosystems to attain various physiological aims remains an intriguing but very challenging task. In this study, the Schiff base reaction was conducted in cells using Sc(OTf)3 as a catalyst, enabling the in situ synthesis of a hollow covalent organic polymer (HCOP) without external stimuli. The reversible Schiff base reaction mediated intracellular Oswald ripening endows the HCOP with a spherical, hollow porous structure and a large specific surface area. The intracellularly generated HCOP reduced cellular motility by restraining actin polymerization, which consequently induced mitochondrial deactivation, apoptosis, and necroptosis. The presented intracellular synthesis system inspired by the Schiff base reaction has strong potential to regulate cell fate and biological functions, opening up a new strategic possibility for intervening in cellular behavior.

Bandgap engineering plays an important role in the regulation of the photophysical properties of semiconductor materials. Developing the facile and powerful strategy to achieve bandgap tunability is highly desired. Herein, the bandgap tunability of scandium microspheres prepared by the hydrothermal treatment of Sc3+ ions/l‐glutamine (Sc3+/Gln) complexes is achieved. The continuously decreased bandgap is directly attributed to the increase of carbon element and the decrease of scandium element in scandium microspheres controlled by the Gln ligand, which causes the red‐shifted room temperature phosphorescence from Sc/Gln‐0.15 (3.17 eV, green) to Sc/Gln‐0.25 (2.53 eV, yellow). Meanwhile, scandium microspheres have an excitation‐dependent emission ranged from green to red color, revealing their multi‐color imaging capability. Further increase of Gln ligand can further reduce the bandgap to 1.62 eV (Sc/Gln‐0.3), realizing the transition from photoluminescence to photothermal properties of scandium microspheres. Because of their superior optical properties, scandium microspheres can be well used for advanced anti‐counterfeiting and multicolor imaging. This new finding not only offers a deeper insight into the photophysical structure of rare earth semiconductor materials, but also provides a scalable method for the preparation of scandium microspheres with the desired bandgaps.

This longitudinal study examined the reciprocal associations between paternal and maternal rejection and firstborn children's (Mage = 49.9 months; 55% boys) behavior problems across the transition to siblinghood in a sample of 120 families recruited from 2016 to 2018 from Shanghai, China. Parental rejection and behavior problems were assessed before (prenatal) and 1, 6, and 12 months after the birth of a baby sibling. Random intercept cross‐lagged panel models revealed positive relations between internalizing problems and both maternal and paternal rejection, and between externalizing problems and paternal rejection at the between‐person level (rs =.32–.37), but only cross‐lagged effects from children's internalizing and externalizing problems to maternal rejection at the within‐person level (βs =.30–.54).

Introduction: Given that coronavirus disease 2019 (COVID‐19) has largely influenced adolescents' physical and mental health around the globe, it is important to identify protective factors that may promote adolescents' positive adjustment during the pandemic. This study aimed to examine the role of parental attachment and COVID‐19 communication in adolescents' health behavior and mental health during COVID‐19. Methods: A total of 442 Chinese parent−adolescent dyads (mean age of adolescents = 13.35 years; 50% girls) completed two‐wave longitudinal surveys over the span of 2 months during the pandemic (Wave 1: July 2020; Wave 2: September 2020). At each wave, adolescents reported on their COVID‐19‐related health behavior, general health behavior, depressive symptoms, and anxiety symptoms. At Wave 1, parent−adolescent attachment security and COVID‐19 communication were also assessed. Results: Adolescents' attachment security to parents was associated with their increased COVID‐19‐related and general health behavior as well as decreased depression and anxiety over 2 months during COVID‐19. Moreover, more frequent parent−adolescent COVID‐19 communication was associated with adolescents' increased COVID‐19‐related and general health behavior over time. Notably, attachment security's and COVID‐19 communication's associations with health behavior largely remained the same after taking into account both factors simultaneously. In addition, results from exploratory analyses suggest that more frequent COVID‐19 communication mediates the link between attachment security and increased health behavior. Conclusions: These findings highlight the importance of promoting attachment security and COVID‐19 communication between parents and adolescents during the pandemic, which may play a positive role in adolescents' health behavior and mental health.

Intraparticle ion motions are critical to the structure and properties of nanomaterials, but rarely disclosed. Herein, in situ visualization of ion motions in a single nanoparticle is presented by dark‐field microscopy imaging, which shows HgCl2‐induced structural transformation of amorphous selenium nanoparticles (SeNPs) with the main composition of Se8. Owing to the high binding affinity with selenium and coulomb interactions, Hg2+ ions can permeate into the interior of SeNPs, making the amorphous Se8 turn to polycrystalline Hg3Se2Cl2. As a proof of concept, SeNPs then serve as a highly effective scavenger for selective removal of Hg2+ ions from solution. This new finding offers visual proof for the photophysical process involving intraparticle ion motion, demonstrating that tracking the ion motions is a novel strategy to comprehend the formation mechanism with the purpose of developing new nanostructures like nanoalloys and nano metal compounds.

Aims: Visceral hypersensitivity in irritable bowel syndrome (IBS) is widespread, but effective therapies for it remain elusive. As a canonical anti‐inflammatory protein, suppressor of cytokine signaling 3 (SOCS3) reportedly relays exchange protein 1 directly activated by cAMP (Epac1) signaling and inhibits the intracellular response to inflammatory cytokines. Despite the inhibitory effect of SOCS3 on the pro‐inflammatory response and neuroinflammation in PVN, the systematic investigation of Epac1‐SOCS3 signaling involved in visceral hypersensitivity remains unknown. This study aimed to explore Epac1‐SOCS3 signaling in the activity of hypothalamic paraventricular nucleus (PVN) corticotropin‐releasing factor (CRF) neurons and visceral hypersensitivity in adult rats experiencing neonatal colorectal distension (CRD). Methods: Rats were subjected to neonatal CRD to simulate visceral hypersensitivity to investigate the effect of Epac1‐SOCS3 signaling on PVN CRF neurons. The expression and activity of Epac1 and SOCS3 in nociceptive hypersensitivity were determined by western blot, RT‐PCR, immunofluorescence, radioimmunoassay, electrophysiology, and pharmacology. Results: In neonatal‐CRD‐induced visceral hypersensitivity model, Epac1 and SOCS3 expressions were downregulated and IL‐6 levels elevated in PVN. However, infusion of Epac agonist 8‐pCPT in PVN reduced CRF neuronal firing rates, and overexpression of SOCS3 in PVN by AAV‐SOCS3 inhibited the activation of PVN neurons, reduced visceral hypersensitivity, and precluded pain precipitation. Intervention with IL‐6 neutralizing antibody also alleviated the visceral hypersensitivity. In naïve rats, Epac antagonist ESI‐09 in PVN increased CRF neuronal firing. Consistently, genetic knockdown of Epac1 or SOCS3 in PVN potentiated the firing rate of CRF neurons, functionality of HPA axis, and sensitivity of visceral nociception. Moreover, pharmacological intervention with exogenous IL‐6 into PVN simulated the visceral hypersensitivity. Conclusions: Inactivation of Epac1‐SOCS3 pathway contributed to the neuroinflammation accompanied by the sensitization of CRF neurons in PVN, precipitating visceral hypersensitivity and pain in rats experiencing neonatal CRD.

We investigated how sibling status and sex of younger siblings influence Chinese adolescents' relationships with their fathers and mothers as a function of resource dilution and preference for sons. The sample included 1,093 adolescents from the 8th grade (Mage = 13.96 years, SD = 0.75 years; 47% girls) and the 11th grade (Mage = 17.25 years, SD = 0.74 years; 57% girls) in a longitudinal study. Consistent with expectations pertaining to the hypothesis of resource dilution and son preference in combination, girls with a younger brother reported less positive relationships with mothers than either singleton girls or girls with a younger sister. No significant difference was found between singleton boys and boys with a younger sibling. The current findings show implications that the resource‐dilution theory and son preference culture together may place girls with a younger brother in an unfavorable condition of resource allocation.

Associations between parent–child relationships and adolescents' shyness are well documented, but relatively little is known about the role of siblings. This three‐wave longitudinal research examined reciprocal associations between parental and sibling warmth and adolescents' shyness in China. One hundred and fifty Chinese adolescents (Mage = 12.84 years; 56.7% girls) participated. Data were collected from multiple sources including self‐reports and peer assessments. Cross‐lagged model analyses revealed unique longitudinal paths from sibling warmth to adolescents' shyness and from adolescents' shyness to sibling warmth. Moreover, no cross‐lagged paths existed between fathers' and mothers' warmth and adolescents' shyness. The results suggest that sibling relationships may be a unique social context for socialization and development among Chinese adolescents. [ABSTRACT FROM AUTHOR]

The associations among parenting behaviors, effortful control, and student engagement in math were examined in a sample of Chinese children. The sample was composed of 778 students (Mage = 10.43 years, SD = 0.99) from Grades 4 to 6 in Shanghai, China. Children completed questionnaires to assess parental warmth and hostility, effortful control, and student engagement in math. The results indicated that parental warmth was positively correlated with math engagement whereas parental hostility was negatively correlated with math engagement. In addition, mediational analyses indicated that effortful control fully mediated the association between parental hostility and math engagement, but partially mediated the association between parental warmth and math engagement. This study offers insights into a mediating mechanism linking the relationships among parenting behaviors, effortful control, and math engagement. [ABSTRACT FROM AUTHOR]

This study explored how maternal involvement in sibling relationships and coparenting behaviors were associated with adolescents' sibling conflicts. Adolescents (Mage = 12.25 years; 47.8% boys) and their mothers from 542 families in China participated in this research. Mothers completed questionnaires that assessed their strategies of involvement in sibling relationships, as well as their perceptions of the quality of their coparenting behaviors. Furthermore, adolescents completed questionnaires that assessed sibling conflicts. Results revealed that the mother's positive guidance was negatively related and their authoritarian control was positively related to sibling conflict. A significant interaction was also found between positive maternal guidance in sibling relationships and undermining coparenting behaviors. These findings underscore the unique and interactive effects of mothers' direct involvement in sibling relationships and coparenting behaviors in adolescents' sibling conflicts.

Little is known about the value of the nutritional risk screening 2002 (NRS2002) scale in nasopharyngeal carcinoma (NPC). We conducted a large‐scale study to address this issue. We employed a big‐data intelligence database platform at our center and identified 3232 eligible patients treated between 2009 and 2013. Of the 3232 (12.9% of 24 986) eligible patients, 469 (14.5%), 13 (0.4%), 953 (29.5%), 1762 (54.5%) and 35 (1.1%) had NRS2002 scores of 1, 2, 3, 4 and 5, respectively. Survival outcomes were comparable between patients with NRS2002 <3 and ≥3 (original scale). However, patients with NRS2002 ≤3 vs >3 (regrouping scale) had significantly different 5‐year disease‐free survival (DFS; 82.7% vs 75.0%, P < .001), overall survival (OS; 88.8% vs 84.1%, P = .001), distant metastasis‐free survival (DMFS; 90.2% vs 85.9%, P = .001) and locoregional relapse‐free survival (LRRFS; 91.6% vs 87.2%, P = .001). Therefore, we proposed a revised NRS2002 scale, and found that it provides a better risk stratification than the original or regrouping scales for predicting DFS (area under the curve [AUC] = 0.530 vs 0.554 vs 0.577; P < .05), OS (AUC = 0.534 vs 0.563 vs 0.582; P < .05), DMFS (AUC = 0.531 vs 0.567 vs 0.590; P < .05) and LRRFS (AUC = 0.529 vs 0.542 vs 0.564; P < .05 except scale A vs B). Our proposed NRS2002 scale represents a simple, clinically useful tool for nutritional risk screening in NPC. [ABSTRACT FROM AUTHOR]

International research on parenting and child development can advance our understanding of similarities and differences in how parenting is related to children's development across countries. Challenges to conducting international research include operationalizing culture, disentangling effects within and between countries, and balancing emic and etic perspectives. Benefits of international research include testing whether findings regarding parenting and child development replicate across diverse samples, incorporating cultural and contextual diversity to foster more inclusive and representative research samples and investigators than has typically occurred, and understanding how children develop in proximal parenting and family and distal international contexts.

An composite comprising amorphous carbon nitride (ACN) and zinc oxide is derived from ZIF-8 by pyrolysis. The composite is a promising anode material for sodium-ion batteries. The nitrogen content of the ACN composite is as high as 20.4 %, and the bonding state of nitrogen is mostly pyridinic, as determined by X-ray photoelectron spectroscopy (XPS). The composite exhibits an excellent Na+ storage performance with a reversible capacity of 430 mA h g−1 and 146 mA h g−1 at current densities of 83 mA g−1 and 8.33 A g−1, respectively. A specific capacity of 175 mA h g−1 was maintained after 2000 cycles at 1.67 A g−1, with only 0.016 % capacity degradation per cycle. Moreover, an accelerating rate calorimetry (ARC) test demonstrates the excellent thermal stability of the composite, with a low self heating rate and high onset temperature (210 °C). These results shows its promise as a candidate material for high-capacity, high-rate anodes for sodium-ion batteries. [ABSTRACT FROM AUTHOR]

Culture has an important impact on attachment. This commentary highlights three aspects about culture and attachment in middle childhood: (1) the need to have a more sophisticated consideration of the implication of cultural values, (2) the need to incorporate the role of societal or political ecological contexts, and (3) the need to solve the cross-cultural issues in measures. © 2015 Wiley Periodicals, Inc.

The purpose of the present study was to examine the relationship between resource acquisition strategies, social functioning and social status in Chinese children. A sample of nearly 500 Chinese children in elementary schools in Shanghai, China, participated in this study. The authors divided the sample into five resource acquisition strategies; based on self-reported use of coercive and pro-social strategies of resource control, they were 'bistrategic controllers' (Machiavellians), 'coercive controllers', 'pro-social controllers', 'non-controllers', or 'typicals'. The results revealed that bistrategic controllers were the most effective in resource control, followed by pro-social and coercive controllers: non-controllers were the least effective. It also indicated that bistrategic and coercive controllers exhibited poor social functioning and low peer status; in contrast, 'typical' controllers emerged as possessing positive social functioning and high peer status. In addition, non-controllers were not at risk with regard to social competence. The results indicate specific cultural 'meanings' of different resource acquisition strategies in Chinese children.

Designing ultralong‐lived aqueous room temperature phosphorescence (RTP) materials has become an actively pursued but challenging research area. Herein, a coordination‐induced structural rigidity (CISR) strategy is proposed to achieve ultralong RTP lifetime in magnesium/pyromellitic acid phosphorescent materials (Mg/PMA‐PMs) with abundant Mg2+ ions sites and hydrophilic groups in aqueous solution. Compared to their dry state (448.77 ms), the lifetime of Mg/PMA‐PMs significantly increases to 1026.17 ms with the addition of a small amount of water (50 wt%). Even in a fully non‐deoxygenated aqueous environment (above 200 wt% water), where Mg/PMA‐PMs disintegrate to form a nanosuspension, they still exhibit an ultralong aqueous RTP lifetime of ≈800 ms. The water‐enhanced RTP properties are attributed to water molecules coordinating with Mg2+ ions and acting as bridging agents to bind with hydrophilic groups through hydrogen bonding. This interaction rigidifies functional groups and inhibits their motions, leading to a substantial reduction in nonradiative decay. Furthermore, the CISR mechanism effectively explains the RTP enhancement effect of water on inorganic salt phosphorescent systems. This work not only provides a new approach for constructing efficient aqueous RTP materials, but also develops a powerful tool for visual anion recognition. [ABSTRACT FROM AUTHOR]

Nanoengineering polar oxide films have attracted great attention in energy storage due to their high energy density. However, most of them are deposited on thick and rigid substrates, which is not conducive to the integration of capacitors and applications in flexible electronics. Here, an alternative strategy using van der Waals epitaxial oxide dielectrics on ultra‐thin flexible mica substrates is developed and increased the disorder within the system through high laser flux. The introduction of defects can efficiently weaken or destroy the long‐range ferroelectric ordering, ultimately leading to the emergence of a large numbers of weak‐coupling regions. Such polarization configuration ensures fast polarization response and significantly improves energy storage characteristics. A flexible BiFeO3‐BaTiO3 (BF‐BT) capacitor exhibits a total energy density of 43.5 J cm−3 and an efficiency of 66.7% and maintains good energy storage performance over a wide temperature range (20–200 °C) and under large bending deformation (bending radii ≈ 2 mm). This study provides a feasible approach to improve the energy storage characteristics of dielectric oxide films and paves the way for their practical application in high‐energy density capacitors.
