Stable α-CsPbI3 with extremely red emission for expanding the color gamut

Science China(Information Sciences) 2024年第5期67卷 311-317页

The wider color gamut represents the better reproducibility of the real natural colors. Perovskite materials exhibit promising potential in full-color wide-gamut displays because of the wide tunability and high saturability of their photon emission. However, the full-color wide gamut(>100% Rec.2020) has not been constructed due to the lack of the extreme red primary color(～700 nm). Herein, the widest color gamut is realized, whereinα-CsPbI3 is used to generate the extreme red primary color. An in-situ encapsulation approach is advised to stabilizeα-CsPbI3 at room temperature by means of polyvinylpyrrolidone(PVP).Theα-CsPbI3 encapsulated by PVP(denoted as P-CPI) shows highly saturated(FWHM(full width at half maximum) ～28 nm) and extremely(～697 nm) red emission. The green emission is provided by P-CPBr(CsPbBr3 with PVP) which is also synthesized using the universal in-situ encapsulation approach. With the assistance of a commercial Ga N chip, the RGB gamut is extended to the widest(151% NTSC, 113%Rec.2020).

引用

Acta Metallurgica sinica(English Letters) 2024年第7期37卷 1161-1176页

作者： Xiaoxue Wang Jingjing Guo Zihao Zeng Peng Zhou Rongqiao Wang Xiuchun Liu Kai Gao Jingli sun Yong yuan Fuhui Wang School of Energy and Power Engineering Beihang UniversityBeijing100191China Beijing Institute of Space Long March Vehicle Beijing100076China The School of Materials Science and Engineering Northeastern UniversityShenyang110819China The State Key Laboratory of Rolling and Automation Northeastern UniversityShenyang110819China Shanghai Spaceflight Precision Machinery Institute Shanghai201600China

The application of Mg alloys is always accompanied by various coating technology, but a reliable model predicting the service life of coatings on Mg alloys is lacking but urgent. In this work, a semi-mechanistic model was proposed to predict the service life of plasma electrolytic oxidation (PEO) coating/electrophoretic coatings on a VW63Z Mg alloy;the model was decomposed into three parts: a first part depicting the degradation time of organic coating (L_(1)) and the diffusion time of electrolyte in the inorganic coating (L_(2)), respectively;a second part interpreting the breakdown of coatings due to the corrosion process (L_(3));a final part establishing an algorithm converting the accelerated tests into the real service environment (α);the effect of structural stress and dissimilar metal joints on the service life of coatings was also considered. Based on the ongoing accelerated experiments, the semi-mechanistic model could be able to predict the service life of both PEO coatings and composite coatings on VW63Z Mg alloy with a satisfiable precision.

Fault Diagnosis for Railway Point Machines Using VMD Multi-scale Permutation Entropy and ReliefF Based on Vibration signals

引用

Chinese Journal of Electronics 2024年

作者： Yongkui sun yuan CAO Peng LI Shuai SU National Engineering Research Center of Rail Transportation Operation and Control System Beijing Jiaotong University School of Automation and Intelligence Beijing Jiaotong University Frontiers Science Center for Smart High-speed Railway System Beijing Jiaotong University

The railway point machine plays an important part in railway systems. It is closely related to the safe operation of trains. Considering the advantages of vibration signals on anti-interference, this paper develops a novel vibration signal-based diagnosis approach for railway point machines. First, variational mode decomposition(VMD)is adopted for data preprocessing, which is verified more effective than empirical mode decomposition. Next, multiscale permutation entropy is extracted to characterize the fault features from multiple scales. Then ReliefF is utilized for feature selection, which can greatly decrease the feature dimension and improve the diagnosis accuracy. By experiment comparisons, the proposed approach performs best on diagnosis for railway point machines. The diagnosis accuracies on reverse-normal and normal-reverse processes are respectively 100% and 98.29%.

Endogenous opioid antinociception is a self-regulatory mechanism that reduces chronic pain, but its underlying circuit mechanism remains largely unknown. Here, we showed that endogenous opioid antinociception required the activation of mu-opioid receptors（MORs） in GABAergic neurons of the central amygdala nucleus（CEA） in a persistent-hyperalgesia mouse model. Pharmacogenetic suppression of these CEAMORneurons, which mimics the effect of MOR activation, alleviated the persistent ***, single-neuron projection analysis revealed multiple projectome-based subtypes of CEAMORneurons, each innervating distinct target brain regions. We found that the suppression of axon branches projecting to the parabrachial nucleus（PB） of one subtype of CEAMORneurons alleviated persistent hyperalgesia, indicating a subtype-and axonal-branch-specific mechanism of action. Further electrophysiological analysis revealed that suppression of a distinct CEA-PB disinhibitory circuit controlled endogenous opioid antinociception. Thus, this study identified the central neural circuit that underlies endogenous opioid antinociception, providing new insight into the endogenous pain modulatory mechanisms.

The Middle Devonian ostracods from the Jiwozhai patch reef in Dushan, Guizhou Province, South China were described for the first time in this study. Twenty-nine species belonging to 20 genera were identified and figured, including a new species named Wangshangkia jiwozhaiensis sp. nov. The ostracod fauna in the Jiwozhai patch reef represents a Givetian age. The ostracod assemblage belongs to the smooth-podocopid association, which is also ecologically equivalent to the Eifelian Mega-Assemblage Ⅲ. This association is indicative of shallow open-marine environments. The Jiwozhai patch reef fauna is primarily comprised of suspension feeders, including filter-feeding ostracods, corals, brachiopods and bryozoans. Ostracods from the Jiwozhai patch reef were compared to the ostracod faunas from Laurentia-Baltica at generic level, which reveals limited faunal exchanges between South China and Laurentia-Baltica during the Middle Devonian.
