1X-ray-charged bright persistent luminescence in NaYF_(4):Ln^(3+)@NaYF_(4) nanoparticles for multidimensional optical information storage显示文摘NaYF_(4):Ln^(3+),due to its outstanding upconversion characteristics,has become one of the most important luminescent nanomaterials in biological imaging,optical information storage,and anticounterfeiting applications.However,the large specific surface area of NaYF_(4):Ln^(3+)nanoparticles generally leads to serious nonradiative transitions,which may greatly hinder the discovery of new optical functionality with promising applications.In this paper,we report that monodispersed nanoscale NaYF_(4):Ln^(3+),unexpectedly,can also be an excellent persistent luminescent(PersL)material.The NaYF_(4):Ln^(3+)nanoparticles with surface-passivated core–shell structures exhibit intense X-ray-charged PersL and narrow-band emissions tunable from 480 to 1060 nm.A mechanism for PersL in NaYF_(4):Ln^(3+)is proposed by means of thermoluminescence measurements and host-referred binding energy(HRBE)scheme,which suggests that some lanthanide ions(such as Tb)may also act as effective electron traps to achieve intense PersL.The uniform and spherical NaYF_(4):Ln^(3+)nanoparticles are dispersible in solvents,thus enabling many applications that are not accessible for traditional PersL phosphors.A new 3-dimensional(2 dimensions of planar space and 1 dimension of wavelength)optical information-storage application is demonstrated by inkjet-printing multicolor PersL nanoparticles.The multicolor persistent luminescence,as an emerging and promising emissive mode in NaYF_(4):Ln^(3+),will provide great opportunities for nanomaterials to be applied to a wider range of fields.Yixi Zhuang Dunrong Chen Wenjing Chen Wenxing Zhang Xin Su Renren Deng Zhongfu An Hongmin Chen Rong-Jun Xie 2021Light(Science & Applications)2021,10,7:12
2On game-based control systems and beyond显示文摘This perspective first expounds on the reasons behind the introduction of the game-based control systems(GBCS),delineates their features,provides some examples,and put forward some research problems.The paper then points out that more complex regulation problems on the now rapidly developing man-machine integration systems may also be investigated by expanding the scope of the GBCS.Renren Zhang Fang Wang Lei Guo 2020National Science Review2020,7,7:3
3Portopulmonary hypertension: Current developments and future perspectives显示文摘Portopulmonary hypertension(POPH)is a severe pulmonary vascular disease secondary to portal hy-pertension and a subset of Group 1 pulmonary hypertension(PH).The pathological changes of POPH are indistinguishable from other PH phenotypes,including endothelial dysfunction,pulmonary vasocon-striction,and vascular remodeling.These changes cause a progressive increase in pulmonary vascular resistance and afterload of the right ventricle,eventually leading to severe right heart failure.The prognosis of POPH is extremely poor among untreated patients.POPH is associated with a high risk of death after liver transplantation(LT),and severe POPH is considered an absolute contraindication for LT.However,pulmonary arterial hypertension(PAH)-targeted therapies are administered to patients with POPH,and aggressive drug treatment significantly optimizes pulmonary hemodynamics and reduces the risk of death.Therefore,early diagnosis,aggressive PAH-targeted therapies,and proper selection of liver transplant candidates are vital to reduce the risk of surgery and improve clinical outcomes.This article aims to review the results of previous studies and describe biological mechanisms,epidemiology,po-tential risk factors,and diagnostic approaches of POPH.Moreover,we introduce recent therapeutic in-terventions for the early diagnosis of POPH and efficient clinical management decisions.Huawei Xu Baoquan Cheng Renren Wang Mengmeng Ding Yanjing Gao 2022Liver Research2022,6,1:2

10Discovery and bioassay of disubstituted β-elemene-NO donor conjugates:synergistic enhancement in the treatment of leukemia显示文摘Natural products are essential sources of antitumor drugs.One such molecule,β-elemene,is a potent antitumor compound extracted from Curcuma wenyujin.In the present investigation,a series of novel 13,14-disubstituted nitric oxide(NO)-donorβelemene derivatives were designed,withβ-elemene as the foundational compound,and subsequently synthesized to evaluate their therapeutic potential against leukemia.Notably,the derivative labeled as compound 13d demonstrated a potent anti-proliferative activity against the K562 cell line,with a high NO release.In vivo studies indicated that compound 13d could effectively inhibit tumor growth,exhibiting no discernible toxic manifestations.Specifically,a significant tumor growth inhibition rate of 62.9%was observed in the K562 xenograft tumor mouse model.The accumulated data propound the potential therapeutic application of compound 13d in the management of leukemia.ZHU Junlong JIANG Xiaoying LUO Xinyu GAO Yuan ZHAO Rui LI Junjie CAI Hong DANG Xiawen YE Xiangyang BAI Renren XIE Tian 2023Chinese Journal of Natural Medicines2023,21,12:1

15Identification of candidate genes that regulate the trade-off between seedling cold tolerance and fruit quality in melon (Cucumis melo L.)显示文摘Trade-offs between survival and growth are widely observed in plants.Melon is an annual,trailing herb that produces economically valuable fruits that are traditionally cultivated in early spring in China.Melon seedlings are sensitive to low temperatures,and thus usually suffer from cold stress during the early growth period.However,little is known about the mechanism behind the trade-offs between seedling cold tolerance and fruit quality in melon.In this study,a total of 31 primary metabolites were detected from the mature fruits of eight melon lines that differ with respect to seedling cold tolerance;these included 12 amino acids,10 organic acids,and 9 soluble sugars.Our results showed that concentrations of most of the primary metabolites in the cold-resistant melons were generally lower than in the cold-sensitive melons;the greatest difference in metabolite levels was observed between the cold-resistant line H581 and the moderately cold-resistant line HH09.The metabolite and transcriptome data for these two lines were then subjected to weighted correlation network analysis,resulting in the identification of five key candidate genes underlying the balancing between seedling cold tolerance and fruit quality.Among these genes,CmEAF7 might play multiple roles in regulating chloroplast development,photosynthesis,and the ABA pathway.Furthermore,multi-method functional analysis showed that CmEAF7 can certainly improve both seedling cold tolerance and fruit quality in melon.Our study identified an agriculturally important gene,CmEAF7,and provides a new insight into breeding methods to develop melon cultivars with seedling cold tolerance and high fruit quality.Lili Li Qiong Li Bin Chen Jiyu Wang Fei Ding Panqiao Wang Xiuyue Zhang Juan Hou Renren Luo Xiang Li Jingwen Zheng Sen Yang Luming Yang Lei Zhu Shouru Sun Changsheng Ma Qin Li Ying Li Jianbin Hu 2023Horticulture Research2023,10,7:0
16Design and control of fraction cutting for the separation of mixed alcohols from the Fischer-Tropsch aqueous by-products显示文摘Since the minimum-boiling azeotropes of C2-C8 alcohols with water and high-water content(up to 95%(mass))in the Fischer-Tropsch aqueous by-products,the separation is energy-intensive and challenging.The energy-saving strategy for the complete separation of the Fischer-Tropsch aqueous by-products has received massive attention in recent decades.In this study,a stripper-sidestream decanter process is proposed by exploiting homogeneous azeotropes(C2-C3 alcohols-water)and heterogeneous azeotropes(C4-C8 alcohols-water).The introduction of the stripping column for pre-dehydration avoids the revaporization of the mixture,and energy carried by the overhead vapor is conserved instead of being removed in a condenser.The precise fraction cutting of C1-C3 alcohol-water mixture,C4-C8 alcohols,and water is realized by the sidestream distillation column.The C4-C8 alcohols rich mixture withdrawn from the sidestream flows into the decanter to break the distillation boundary,where the organic phase returns to the sidestream distillation column to obtain the dehydrated C4-C8 alcohols,and the aqueous phase enters the stripping column.Steady-state optimization based on total annual cost(TAC)minimization shows that the stripper-sidestream decanter process reduces TAC by 17.00%and saves energy by 21.27%compared with the conventional three-column distillation process.Further,a control structure of the process is established,and dynamic simulations show that the control structure combining a differential controller with a low-selector exhibits robust co ntrol.This study provides a novel design scheme and deepens the insights into the efficient separation of aqueous by-products of the Fischer-Tropsch synthesis.Renren Zhang Yang Huang Kaitian Zheng Chunjian Xu 2022Chinese Journal of Chemical Engineering2022,,10:0
