This research aims to investigate the salience of mothers’ emotional expressivity and its links with adolescents’ emotional wellbeing and expressivity in an urban society endorsing more individualism and a rural society ascribing to more collectivism. By comparing Chinese urban (N = 283, Mage = 14.13) and rural (N = 247, Mage = 14.09) adolescents, this research found that urban mothers’ expression of positive-dominant and positive-submissive emotions (PD and PS) were more common while expression of negative-dominant (ND) emotions was less common than rural mothers’. PD and PS had significant links with urban and rural adolescents’ increased emotional expressivity and self-esteem, however, only significantly related to urban adolescents’ decreased depression but not with rural adolescents’. ND had significant links with both urban and rural adolescents’ expression of negative emotions, however, only significantly correlated with urban adolescents’ less level of self-esteem and rural adolescents’ more expression of positive emotions. No significant difference was found in the salience of urban and rural mothers’ expression of negative-submissive (NS) emotions, which positively related to both urban and rural adolescents’ depression and emotional expressivity. Moreover, we found that adolescents’ emotional wellbeing (i.e., self-esteem and depression) mediated the relationship between mothers’ emotional expressivity and adolescents’ expressivity in both societies. Overall, the study findings document that the salience of mothers’ emotional expressivity and its relations with adolescents’ emotional adjustment differ between urban and rural societies.

Novel NiMoO4-integrated electrode materials were successfully prepared by solvothermal method using Na2MoO4·2H2O and NiSO4·6H2O as main raw materials, water, and ethanol as solvents. The morphology, phase, and structure of the as-prepared materials were characterized by SEM, XRD, Raman, and FT-IR. The electrochemical properties of the materials in supercapacitors were investigated by cyclic voltammetry, constant current charge–discharge, and electrochemical impedance spectroscopy techniques. The effects of volume ratio of water to ethanol (W/E) in solvent on the properties of the product were studied. The results show that the pure phase monoclinic crystal NiMoO4 product can be obtained when the W/E is 2:1. The diameter and length are 0.1–0.3 µm and approximately 3 µm, respectively. As an active material for supercapacitor, the NiMoO4 nanorods material delivered a discharge specific capacitance of 672, 498, and 396 F/g at a current density of 4, 7, and 10 A/g, respectively. The discharge specific capacitance slightly decreased from 815 to 588 F/g with a retention of 72% after 1000 cycles at a current density of 1 A/g. With these superior capacitance properties, the novel NiMoO4 integrated electrode materials could be considered as promising material for supercapacitors.

Underground Nuclear Astrophysics in China (JUNA) will take the advantage of the ultra-low background in Jinping underground lab. High current accelerator with an ECR source and detectors were commissioned. JUNA plans to study directly a number of nuclear reactions important to hydrostatic stellar evolution at their relevant stellar energies. At the first period, JUNA aims at the direct measurements of 25Mg(p,γ)26 Al, 19F(p,α) 16 O, 13C(α, n) 16O and 12C(α,γ) 16O near the Gamow window. The current progress of JUNA will be given.

Cesium lead iodide perovskite (CsPbI3) with excellent optical and electrical properties have attracted numerous academic attentions. Specifically, the black cubic phase CsPbI3 with a direct band gap of 1.74 eV has been most appropriate materials for various optoelectronic applications, especially for photovoltaic (PV), Light-Emitting Diodes (LED) and photodetector applications1. However, the preferred cubic phase of bulk CsPbI3 (α-CsPbI3) is usually only stable at high temperatures and it will undergo an immediate phase transformation to orthorhombic phase (δ-CsPbI3) after fabrication at room temperature. In this work, we have discovered a convenient CVD method to investigate the growth behavior of the cubic α-CsPbI3 film on the porous alumina substrate. The lead iodide and cesium iodide were used as the precursors for the deposition of CsPbI3. The porous alumina with high surface area and large pore volume was used as growth substrate. It was shown that the porous alumina promoted the growth of CsPbI3 film by absorbing the precursor and increasing the nucleation density. The prepared CsPbI3 film emitted strong and stable red light under ultraviolet light excitation at room temperature and ambient atmosphere. The lead iodide was absorbed on the surface of the porous alumina firstly then reacted with cesiumiodide to form the CsPbI3. The successful preparation of the CsPbI3 by the direct CVD method paves the way for its large scale growth and application in optoelectronic devices.

We report a novel approach to the instantaneous photoinitiated synthesis of mixed anatase-rutile nanocrystalline TiO2 thin films with a three-dimensional nanostructure through pulsed white light irradiation of photosensitive Ti-organic precursor films. Pulsed photoinitiated pyrolysis accompanied by instantaneous self-assembly and crystallization occurred to form graphitic oxides-coated TiO2 nanograins. Subsequent pulsed light irradiation working as in situ pulsed photothermal treatment improved the crystalline quality of TiO2 film despite its low attenuation of light. The non-radiative recombination of photogenerated electrons and holes in TiO2 nanograins, coupled with inefficient heat dissipation due to low thermal conductivity, produces enough heat to provide the thermodynamic driving force for improving the crystalline quality. The graphitic oxides were reduced by pulsed photothermal treatment and can be completely removed by oxygen plasma cleaning. This photoinitiated nanofabrication technology opens a promising way for the low-cost and high-throughput manufacturing of nanostructured metal oxides as well as TiO2 nanocrystalline thin films.

Proteomic approaches based on two-dimensional gel electrophoresis, mass spectrometry and database search are widely used to address questions about the development, physiology and quality of seeds. Identification of proteins is of great importance in proteomic analyses. For seed crops without full genome information, cross-species protein identification by mass spectrometry-driven sequence similarity search can be used. However, this approach is risky due to protein polymorphism between different species. Species-specific expressed sequence tag (EST) databases are an invaluable resource, which complements mass spectrometry data analysis for protein identification. Here, we illustrate a modified method of protein identification and characterization using species-specific EST databases and peptide mass fingerprinting with an example of protein identification. This method is reliable, supplements the existing methods, and improves the efficiency and accuracy of protein identification for seed crops for which complete genome information is not available.
