| 1 | Research progress on solidification structure of alloys by synchrotron X-ray radiography: A review显示文摘The synchrotron radiation technology has recently emerged as a powerful tool to characterize the real-time microstructure evolution during solidification of alloys.Compared with other methods,the synchrotron radiation technology,along with its unique advantages of strong brightness,high energy,excellent resolution,and good monochromaticity,allows for capturing the dendrite evolution behavior of alloys in real time and can be dynamically coordinated with high-resolution CCD(Charge-coupled Device)imaging systems.This paper briefly reviews the recent advances in developing synchrotron radiation for solidification of alloys with low,medium,and high melting points,and under the external electric,magnetic,and ultrasonic fields.Furthermore,a series of microstructural features and behaviors such as dendrite morphology,growth orientation,dendrite fracture,and rotation are described in detail.Finally,the development trends and application prospects of synchrotron radiation technology in alloy solidification are forecasted. | Yongbiao Wang Sensen Jia Mingguang Wei Liming Peng Yujuan Wu Xintian Liu | 2020 | Journal of Magnesium and Alloys2020，8，2： | 5 |
| 2 | SCGN deficiency is a risk factor for autism spectrum disorder显示文摘Autism spectrum disorder(ASD)affects 1-2%of all children and poses a great social and economic challenge for the globe.As a highly heterogeneous neurodevelopmental disorder,the development of its treatment is extremely challenging.Multiple pathways have been linked to the pathogenesis of ASD,including signaling involved in synaptic function,oxytocinergic activities,immune homeostasis,chromatin modifications,and mitochondrial functions.Here,we identify secretagogin(SCGN),a regulator of synaptic transmission,as a new risk gene for ASD.Two heterozygous loss-of-function mutations in SCGN are presented in ASD probands.Deletion of Scgn in zebrafish or mice leads to autism-like behaviors and impairs brain development.Mechanistically,Scgn deficiency disrupts the oxytocin signaling and abnormally activates inflammation in both animal models.Both ASD probands carrying Scgn mutations also show reduced oxytocin levels.Importantly,we demonstrate that the administration of oxytocin and anti-inflammatory drugs can attenuate ASD-associated defects caused by SCGN deficiency.Altogether,we identify a convergence between a potential autism genetic risk factor SCGN,and the pathological deregulation in oxytocinergic signaling and immune responses,providing potential treatment for ASD patients suffering from SCGN deficiency.Our study also indicates that it is critical to identify and stratify ASD patient populations based on their disease mechanisms,which could greatly enhance therapeutic success. | Zhe Liu Shuai Tan Lianyu Zhou Li Chen Mingfeng Liu Wang Wang Yingying Tang Qin Yang Sensen Chi Peiyan Jiang Yue Zhang Yonghua Cui Junhong Qin Xiao Hu Shenglong Li Qi Liu Lu Chen Song Li Ezra Burstein Wei Li Xiaohu Zhang Xianming Mo Da Jia | 2023 | Signal Transduction and Targeted Therapy2023，8，2： | 0 |
| 3 | Complementary multicolor electrochromic devices with excellent stability based on porous tin oxide nanosheet scaffold显示文摘Electrochromic devices(ECDs)have been extensively investigated as promising candidates in broad cutting-edge applications,such as smart windows,electronic labels,adaptive camouflage,etc.However,they have suffered from either inadequate color variations or poor cycling stability for a long time.Herein,we developed a general strategy to boost the cyclic stability and enrich the color variations of ECDs by scrupulous design of the composition and nanostructure of electrodes,in which porous tin oxide(SnO_(2))nanosheets serve as the scaffold and typical metal oxides or conducting polymers as the active electrochromic materials.Various electrochromic composite materials,including polyaniline(PANI)@SnO_(2),V2O5@SnO_(2),and WO_(3)@SnO_(2) heterostructured nanoarrays were prepared by the facile wet-chemical method.These composite electrodes exhibit remarkable electrochromic performances,e.g.,superior cycling stability(more than 2000 cycles),rich color variations(more than 5 colors for PANI@SnO_(2)),and enlarged optical modulation.These excellent performances account for the heterogenous porous nanoarrays,which not only facilitate the intercalation/extraction of ions but also relieve the stress generated during the electrochemical process.In addition,diverse prototypes of complementary multicolor ECD with excellent cycling stability(over thousands of cycles)and rich color variations(8 colors)were realized for the first time.We believe that our work put forward a general strategy for developing high-quality multicolor complementary electrochromic devices. | Chenchen Bian Jinhui Wang Huanhuan Liu Yin Yan Ping Zhang Weilong Yang Sensen Jia Xiaodan Guo Guofa Cai | 2024 | Nano Research2024，17，4： | 0 |
