1Pityriasis rubra pilaris (PRP) with preceding Epstein-Barr virus infection:a new type PRP with non-HIV virus infection?显示文摘To the editor:A 28-year-old Chinese man presented with multiple orange yellow papules and erythematous with fine scales and subtle follicular prominence on his face,scalp,trunk and extremities on February 1,2012.Four weeks earlier (December 30,2011),multiple orange yellow papules had appeared firstly on the face,along with a fever (Tmax 38.5℃) and pharyngalgia.Gradually the skin lesions extended to the head,trunk and extremities and developed scales.The palmoplantar surfaces displayed erythema and hyperkeratosis (Figure 1A).Histopathological examinations were consistent with pityriasis rubra pilaris (PRP) (Figure 1B).The laboratory tests revealed a white cell count of 11.33× 109/L (neutrophils 29.7%,lymphocytes 60.8%) decreased to 7.09× 109/L (neutrophils 41.2%,lymphocytes 49%) one month later (January 3,2012).Epstein-Barr virus (EBV) viral capsid antigen immune globulin G (IgG/VCA) antibody was positive (2.78 in enzyme immunoassay;normal range <0.80;results presented as arbitrary units) and increased to 4.33 one month later (January 3,2012).EBV IgM/VCA antibody levels were high (7.14;normal range <0.8) and decreased to 3.05.Detection of EBV-DNA copies was not done on December 30,2011.However,it showed a negative result on January 3,2012.EBER-in situ hybridization (EBER-ISH) showed a negative result in the skin biopsy slides.These results suggested that this patient suffered from primary EBV infection.Rest tests,such as other virus infections,malignances,autoimmune diseases were normal or negative.For treatment,the patient received 0.1% tarcrolimus ointment;the lesions generally disappeared and no new lesions have been observed during 3 months of follow-up.Wang Tao Liu Jie Liu Yuehua Zheng Heyi 2014Chinese Medical Journal2014,,12:2
2Recent progress on three-dimensional nanoarchitecture anode materials for lithium/sodium storage显示文摘High-performance batteries with high density and low cost are needed for the development of largescale energy storage fields such as electric vehicles and renewable energy systems.The anode with threedimensional(3D)nanoarchitecture is one of the most attractive candidates for high-performance lithiumion batteries(LIBs)and sodium-ion batteries(SIBs)due to its efficient electron/ion transport and high active material mass loading.Although some important breakthroughs have been made in 3D nanoarchitecture anode materials,more improvements are still needed for high cycling stability and high energy density.Herein,the latest research progress of 3D nanoarchitecture anode materials for LIBs and SIBs is reviewed,including nanoporous metal,nanoporous graphene,and their derived foams.Specifically,the storage properties of Li/Na ions,the kinetics of ion/electron transport,and specific chemical interactions are discussed based on the structure design.In addition,the research strategies and structural characteristics of 3D nanoarchitecture anode materials are summarized,providing a reference for the further development of LIBs and SIBs.Meanwhile,the future research directions of LIBs and SIBs have also prospected.Zhijia Zhang Yuefang Chen Shihao Sun Kai Sun Heyi Sun Hongwei Li Yuhe Yang Mengmeng Zhang Weijie Li Shulei Chou Huakun Liu Yong Jiang 2022Journal of Materials Science & Technology2022,,24:2

15Grain boundaries contribute to highly efficient lithium-ion transport in advanced LiNi_(0.8)Co_(0.15)Al_(0.05)O_(2)secondary sphere with compact structure显示文摘LiNi_(0.8)Co_(0.15)Al_(0.05)O_(2)(NCA)secondary particles with high tap density have a great potential for high volumetric energy density lithium(Li)-ion power bat-tery.However,the ionic conductivity mechanism of NCA with compact structure is still a suspense,especially the function of grain boundaries.Herein,we sys-tematically investigate the Li-ion transport behavior in both the primitive NCA(PNCA)secondary sphere densely grown by single-crystal primary grains and ball-milled NCA(MNCA)nanosized particle to reveal the role of grain bound-aries for Li-ion transport.The PNCA and MNCA have comparable Li-ion dif-fusion coefficients and rate performance.Moreover,the graphene nanosheet conductive additive only mildly affects the Li-ion diffusion in PNCA cathode,while which severely blocks the Li-ion transport in MNCA cathode.Through high-resolution transmission electron microscopy and electron energy loss spec-troscopy,we clearly observe Li-ion depletion at lower state of charge(SOC)and Li-ion aggregation at high SOC along the grain boundaries of PNCA secondary particles during high-rate lithiation process.The grain boundaries can construct an interconnected Li-ion transport network for highly efficient Li-ion transport,which contributes to excellent high-rate performance of compact PNCA sec-ondary particles.These findings present new strategy and deep insight in design-ing compact materials with excellent high-rate performance.Cheng Liu Heyi Xia Yinping Wei Jiabin Ma Lin Gan Feiyu Kang Yan-Bing He 2021SusMat2021,1,2:0
16Electrolyte-gated transistors for neuromorphic applications显示文摘Von Neumann computers are currently failing to follow Moore’s law and are limited by the von Neumann bottleneck.To enhance computing performance,neuromorphic computing systems that can simulate the function of the human brain are being developed.Artificial synapses are essential electronic devices for neuromorphic architectures,which have the ability to perform signal processing and storage between neighboring artificial neurons.In recent years,electrolyte-gated transistors(EGTs)have been seen as promising devices in imitating synaptic dynamic plasticity and neuromorphic applications.Among the various electronic devices,EGT-based artificial synapses offer the benefits of good stability,ultra-high linearity and repeated cyclic symmetry,and can be constructed from a variety of materials.They also spatially separate“read”and“write”operations.In this article,we provide a review of the recent progress and major trends in the field of electrolyte-gated transistors for neuromorphic applications.We introduce the operation mechanisms of electric-double-layer and the structure of EGT-based artificial synapses.Then,we review different types of channels and electrolyte materials for EGT-based artificial synapses.Finally,we review the potential applications in biological functions.Heyi Huang Chen Ge Zhuohui Liu Hai Zhong Erjia Guo Meng He Can Wang Guozhen Yang Kuijuan Jin 2021Journal of Semiconductors2021,42,1:0

18Photocatalytic degradation of 2,4,6-trinitrotoluene显示文摘A Pt/TiO2 photocatalyst was used in the photocatalytic degradation of 2,4,6-trinitrotoluene (TNT) under the irradiation of the simulated sunlight. The results show that the destruction of TNT is faster and more complete with the photocatalyst. The photocatalytic degradation of TNT follows first order kinet-ics. The transformation of nitryl groups of TNT molecules into nitrite and nitrate ions may be acceler-ated in the presence of the Pt/TiO2 photocatalyst. Compared with that without the catalyst, the concentration of nitrate ions was improved 32.3 times within 2.5 h.LIU XiuHua FU YiBei WANG HeYi ZHONG ZhiJing XU YunShu 2008Science China Chemistry2008,51,10:0
