High-quality friendships are important sources of social support for adolescents. However, friendships characterized by negative features such as frequent conflicts with friends can be significant interpersonal stressors and are detrimental to adolescents' mental health and well-being. The present study aimed to examine the associations between friendship conflict and three negative emotional states commonly experienced during adolescence (i.e., depression, anxiety, and stress), test the moderating effect of self-compassion on these associations, and investigate whether the moderating effect differed by gender. A total of 861 Chinese adolescents (45.76% girls; M
age = 15.21, SD = 0.73) completed a suite of questionnaires measuring friendship conflict, self-compassion, depression, anxiety, and stress. Utilizing latent interaction models, we found that friendship conflict was positively associated with depression, anxiety, and stress, respectively, while self-compassion was negatively associated with these negative emotions. More importantly, self-compassion moderated the associations between friendship conflict and the three negative emotions, such that the positive associations between friendship conflict and depression, anxiety, and stress were weaker among adolescents with higher levels of self-compassion. We further conducted multiple group analyses and found that the moderating role of self-compassion was only found for boys, but not for girls. These findings highlighted the protective role of self-compassion in helping adolescents, especially boys, cope with friendship conflict. Highlights: Friendship conflict could trigger depression, anxiety, and stress in Chinese adolescents. Self-compassion served as a moderator between friendship conflict and negative emotional states. However, the moderating effect of self-compassion was only supported among boys. [ABSTRACT FROM AUTHOR]- Published

We present a dry pick-and-flip assembly technique for angle-resolved photoemission spectroscopy (ARPES) of van der Waals heterostructures. By combining Elvacite2552C acrylic resin and 1-ethyl-3-methylimidazolium ionic liquid, we prepared polymers with glass transition temperatures (T
g ) ranging from 37 to 100 ℃. The adhesion of the polymer to the 2D crystals was enhanced at T g . By utilizing the difference in T g , a 2D heterostructure can be transferred from a high- T g polymer to a lower- T g polymer, which enables flipping its surface upside down. This process is suitable for assembling heterostructures for ARPES, where the top capping layer should be monolayer graphene. The laser-based micro-focused ARPES measurements of 5-layer WTe2 , 3-layer MoTe2 , 2-layer WTe2 /few-layer Cr2 Ge2 Te6 , and twisted double bilayer WTe2 demonstrate that this process can be utilized as a versatile sample fabrication method for investigating the energy spectra of 2D heterostructures.

The development of antimicrobial fabrics and textiles that can sustainably inhibit a broad spectrum of microbes is crucial for protecting against pathogens in various environments. However, engineering antimicrobial textiles is challenging due to issues with discoloration and inhibited breathability, the use of harmful or harsh reagents and synthesis conditions, and complex and/or time-consuming processing. Herein, we develop a facile and rapid approach to deposit antimicrobial coatings using universally adherent plant polyphenols and antimicrobial silver ions. Importantly, the coatings are colorless, thin (< 10 nm), rapidly assembled (< 20 min), and can be deposited via immersion or spraying. We demonstrate that these metal-phenolic coatings on textiles can inhibit lipid-enveloped viruses over one thousand times more efficiently than coatings composed of other metal ions, while maintaining their efficacy even after 5 washes. Moreover, the coatings also inhibit Gram positive and negative bacteria, and fungi, and can prevent odors on clothes for at least 10 washes. Collectively, the ease of synthesis, use of simple and safe precursors, and amenability to at-home and industrial application suggests that the coatings will find practical application in various settings.

- Abstract
In this study, we investigated the effects of 6-benzylaminopurine (6-BA)-calcium chloride (CaCl
2 )-salicylic acid (SA) treatment on the yellowing and reactive oxygen metabolism of harvested broccoli heads. We dipped fresh broccoli heads in a compound solution (0.6 mmol/L 6-BA + 40 mmol/L CaCl2 + 3 mmol/L SA) for 5 min and then stored them at 23 °C for 4 days. The results showed that the 6-BA-CaCl2 -SA postharvest treatment effectively retarded the increase in color values (e.g., variations from black to white, from green to red, and from blue to yellow) and the decline in chlorophyll content of the broccoli heads. Compared with the control broccoli, the rate of superoxide anion radical (O2 ·− ) production and the hydrogen peroxide (H2 O2 ) content were lowered by the treatment. We also found significant differences in the activities of superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD) in the treated broccoli. Based on these results, we consider 6-BA-CaCl2 -SA to inhibit the accumulation of reactive oxygen, delay the degradation of chlorophyll, and prolong the shelf life of broccoli heads at 23 °C.

Based on the available thermodynamic parameters and experimental diffusivities in the literature as well as measured in the present work, the diffusion mobilities of Ni, Cr, and Mo for fcc Ni-Cr-Mo alloys have been assessed by means of the CALPHAD method. Comprehensive comparisons between the calculated and experimental data show that an excellent agreement is obtained for the diffusion data of ternary diffusion couples, such as the interdiffusion coefficients, concentration profiles, and the diffusion path.

- Abstract
Aims: Drought events during the seedling stage of winter wheat are increasing in Huaibei Plain of China due to global warming, which lowers seedling quality and reduces crop productivity. This study aimed to explore the effect of irrigation methods and topsoil compaction on the seedling growth in this region.We conducted a two-year filed experiment to evaluate the effect of three irrigation practices and topsoil compaction on the shoot and root growth of seedlings. The irrigation methods include rain-fed (RI), traditional flood irrigation (TI) and micro-sprinkling irrigation (MI). Topsoil compaction after wheat sowing was used under each irrigation method (RC, TC and MC). Various above-ground of plant, root traits and physiological data, and the dynamic of soil water content, were recorded.The results demonstrated that MI maintained the highest water content in 0–20 cm soil profile at overwintering stage compared to TI, and TI was significantly higher than RI. MI had higher dry matter accumulation, the number of tillers and roots than TI and RI due to it obtained the highest leaf area index, chlorophyll content, root density and activity, while RI was the lowest levels. The relative growth rate, net assimilation rate and crop growth rate of seedlings were improved in MI than those of TI and RI. Topsoil compaction greatly promoted the growth of seedlings in RI at overwintering stage, and increased the dry matter accumulation in TI.Micro-sprinkling irrigation and topsoil compaction can be used as effective measure to promote the growth of wheat seedling and improve its quality by increasing leaf production and strengthening the root system in the Huaibei Plain region.Methods: Drought events during the seedling stage of winter wheat are increasing in Huaibei Plain of China due to global warming, which lowers seedling quality and reduces crop productivity.
