| 1 | Selective catalytic reduction of NO_(x) with NH_(3):opportunities and challenges of Cu-based small-pore zeolites显示文摘Zeolites,as efficient and stable catalysts,are widely used in the environmental catalysis field.Typically,Cu-SSZ-13 with small-pore structure shows excellent catalytic activity for selective catalytic reduction of NO_(x) with ammonia(NH_(3)-SCR)as well as high hydrothermal stability.This review summarizes major advances in Cu-SSZ-13 applied to the NH_(3)-SCR reaction,including the state of copper species,standard and fast SCR reaction mechanism,hydrothermal deactivation mechanism,poisoning resistance and synthetic methodology.The review gives a valuable summary of new insights into the matching between SCR catalyst design principles and the characteristics of Cu^(2+)-exchanged zeolitic catalysts,highlighting the significant opportunity presented by zeolite-based catalysts.Principles for designing zeolites with excellent NH_(3)-SCR performance and hydrothermal stability are proposed.On the basis of these principles,more hydrothermally stable Cu-AEI and Cu-LTA zeolites are elaborated as well as other alternative zeolites applied to NH_(3)-SCR.Finally,we call attention to the challenges facing Cu-based small-pore zeolites that still need to be addressed. | Yulong Shan Jinpeng Du Yan Zhang Wenpo Shan Xiaoyan Shi Yunbo Yu Runduo Zhang Xiangju Meng Feng-Shou Xiao Hong He | 2021 | National Science Review2021，8，10： | 9 |
| 2 | Uncommon EGFR mutations in a cohort of Chinese NSCLC patients and outcomes of first-line EGFR-TKIs and platinum-based chemotherapy显示文摘Objective: Data on the clinical activity of epidermal growth factor receptor(EGFR) tyrosine kinase inhibitors(TKIs) in patients with non-small-cell lung cancer(NSCLC) and uncommon EGFR mutations remain insufficient.This study aimed to investigate the effect of first-line EGFR-TKIs or platinum-based chemotherapy in NSCLC patients with uncommon EGFR mutations.Methods: We retrospectively enrolled 504 patients with EGFR-mutant NSCLC.The clinical characteristics and treatment outcomes were collected and compared between patients with common and uncommon EGFR-mutant NSCLC.Results: Seventy patients(13.9%) harboring uncommon EGFR mutations were included.Thirty of these patients received EGFR-TKIs and 40 received platinum-based chemotherapy as first-line therapy.The objective response rate(ORR) and median progression-free survival(m PFS) of patients treated with TKIs in the uncommon mutation group was significantly inferior to that in the common mutation group(ORR: 23.3% vs.51.8%,P=0.003; m PFS:7.1 vs.10.9 months,P<0.001).In the uncommon group,m PFS was similar between first-line EGFR-TKIs treatment and platinum-based chemotherapy(7.1 vs.6.1 months,P=0.893).In patients with EGFR G719 X or L861 Q mutations,the m PFS was longer in the first-line EGFR-TKIs treatment group than in the chemotherapy group,but the difference was not statistically significant(G719 X: 8.2 vs.5.8 months,P=0.061; L861 Q: 7.6 vs.4.1 months,P=0.872).Multivariate analyses identified adenocarcinoma(P=0.003) as the independent predictive factor for PFS in patients with uncommon EGFR mutations who were treated with first-line EGFR-TKIs.Conclusions: The current study demonstrated that the effect of first-line EGFR-TKIs was similar to that of platinum-based chemotherapy in patients with uncommon EGFR-mutant NSCLC.Adenocarcinoma was the independent predictive factor for PFS in uncommon EGFR-mutant NSCLC patients treated with first-line EGFRTKIs. | Jinpeng Shi Hui Yang Tao Jiang Xuefei Li Chao Zhao Limin Zhang Sha Zhao Xiaozhen Liu Yijun Jia Yan Wang Lei Xi Shijia Zhang Chunxia Su Shengxiang Ren Caicun Zhou | 2017 | Chinese Journal of Cancer Research2017，29，6： | 6 |
| 3 | Highly reversible lead-carbon battery anode with lead grafting on thecarbon surface显示文摘A novel C/Pb composite has been successfully prepared by electroless plating to reduce the hydrogen evolution and achieve the high reversibility of the anode of lead-carbon battery(LCB). The deposited lead on the surface of C/Pb composite was found to be uniform and adherent to carbon surface. Because lead has been stuck on the surface of C/Pb composite, the embedded structure suppresses the hydrogen evolution of lead-carbon anode and strengthens the connection between carbon additive and sponge lead.Compared with the blank anode, the lead-carbon anode with C/Pb composite displays excellent charge—discharge reversibility, which is attributed to the good connection between carbon additives and lead that has been stuck on the surface of C/Pb composite during the preparation process. The addition of C/Pb composite maintains a solid anode structure with high specific surface area and power volume, and thereby, it plays a significant role in the highly reversible lead-carbon anode. | Jian Yin Nan Lin Wenli Zhang Zheqi Lin Ziqing Zhang Yue Wang Jun Shi Jinpeng Bao Haibo Lin | 2018 | Journal of Energy Chemistry2018，27，6： | 6 |
| 4 | Finite-time command filtered adaptive control for nonlinear systems via immersion and invariance显示文摘This paper investigates the problem of finite-time adaptive output tracking control for strictfeedback nonlinear systems with parametric uncertainties. Command signals and their derivatives are generated by a new command filter based on a second-order finite-time differentiator, which attenuates the chattering phenomenon. The parameter estimations are achieved by an immersion and invariance approach without requiring the certainty equivalence principle. The finite-time adaptive controller is constructed via a backstepping design method, a finite-time command filter, and a modified fractional-order error compensation mechanism. The proposed control strategy guarantees the finite-time boundedness of all signals in the closed-loop system, and the tracking error is driven into an arbitrarily small neighborhood of the origin in finite time. Finally, the new design technique is validated in a simulation example of the electromechanical system. | Jinpeng YU Peng SHI Xinkai CHEN Guozeng CUI | 2021 | Science China(Information Sciences)2021，64，9： | 4 |
| 5 | Preparation of Au nanoparticles modified TiO_2 nanotube array sensor and its application as chemical oxygen demand sensor显示文摘Au nanoparticles(AuNPs) were electrodeposited at the highly ordered anatase TiO_2 nanotube array(TiO_2 NA) electrode under sonicating, and the AuNP-TiO_2 NA sensor was characterized by scanning electron microscope(SEM), X-ray photoelectron spectroscopy(XPS), X-ray diffraction(XRD). The photoelectrochemical experiments indicate the AuNP-TiO_2 NA sensor has lower photoelectro-resistance,higher photoelectrocatalytical activity and stability than that of pure TiO_2 NA sensor under the same conditions. The as-prepared sensor can be used for the determination of chemical oxygen demand(COD)in real samples, and the obtained results are comparable well with those of by standard K_2Cr_2O_7 method.The method proposed is simple, fast, cost effective, and environmentally friendly. | Longqi Liang Jiao Yin Jinpeng Bao Linchuan Cong Weimin Huang Haibo Lin Zhan Shi | 2019 | Chinese Chemical Letters2019，30，1： | 2 |
| 6 | Lead‑Carbon Batteries toward Future Energy Storage:From Mechanism and Materials to Applications显示文摘The lead acid battery has been a dominant device in large-scale energy storage systems since its invention in 1859.It has been the most successful commercialized aqueous electrochemical energy storage system ever since.In addition,this type of battery has witnessed the emergence and development of modern electricity-powered society.Nevertheless,lead acid batteries have technologically evolved since their invention.Over the past two decades,engineers and scientists have been exploring the applications of lead acid batteries in emerging devices such as hybrid electric vehicles and renewable energy storage;these applications necessitate operation under partial state of charge.Considerable endeavors have been devoted to the development of advanced carbon-enhanced lead acid battery(i.e.,lead-carbon battery)technologies.Achievements have been made in developing advanced lead-carbon negative electrodes.Additionally,there has been significant progress in developing commercially available lead-carbon battery products.Therefore,exploring a durable,long-life,corrosion-resistive lead dioxide positive electrode is of significance.In this review,the possible design strategies for advanced maintenance-free lead-carbon batteries and new rechargeable battery configurations based on lead acid battery technology are critically reviewed.Moreover,a synopsis of the lead-carbon battery is provided from the mechanism,additive manufacturing,electrode fabrication,and full cell evaluation to practical applications. | Jian Yin Haibo Lin Jun Shi Zheqi Lin Jinpeng Bao Yue Wang Xuliang Lin Yanlin Qin Xueqing Qiu Wenli Zhang | 2022 | Electrochemical Energy Reviews2022，5，3： | 1 |

| 10 | Batch fabrication of MoS_(2) devices directly on growth substrates by step engineering显示文摘Monolayer molybdenum disulfide(MoS_(2))has emerged as one of the most promising channel materials for next-generation nanoelectronics and optoelectronics owing to its atomic thickness,dangling-bond-free flat surface,and high electrical quality.Currently,high-quality monolayer MoS_(2)wafers are primarily grown on sapphire substrates incompatible with conventional device fabrication,and thus transfer processes to a suitable substrate are typically required before the device can be processed.Here,we demonstrate the batch production of transfer-free MoS2 top-gate devices directly on sapphire growth substrates via step engineering.By introducing substrate steps on growth substrate sapphire,high-κdielectric layers with superior quality and uniform can be directly deposited on the epitaxially grown monolayer MoS_(2).For the substrate with a maximum step density of 100μm^(−1),the gate capacitance can reach~1.87μF∙cm^(−2),while the interface trap state density(Dit)can be as low as~7.6×10^(10)cm^(−2)∙eV^(−1).The direct deposition of high-quality dielectric layers on grown monolayer MoS2 enables the batch fabrication of top-gate devices devoid of transfer and thus excellent device yield of>96%,holding great promise for large-scale twodimensional(2D)integrated circuits. | Lu Li Yalin Peng Jinpeng Tian Fanfan Wu Xiang Guo Na Li Wei Yang Dongxia Shi Luojun Du Guangyu Zhang | 2023 | Nano Research2023，16，11： | 0 |
| 11 | Characterization and implications of prokaryotic ribosome-binding sites across species显示文摘The ribosome-binding site(RBS)in the 5′untranslated region is recognized by 16S rRNA to start translation and is an essential element of the gene expression system.RBSs have been widely applied in regulating gene expression in various scenarios,including Gram-negative or Gram-positive bacteria.Here,we first rationally designed and constructed an RBS mutant library containing 66 RBSs.The strength of these RBSs in E.coli and C.glutamicum was characterized individually.The RBS strength spanned about 200 and 15 times in the two species,respectively.The strength of RBSs in C.glutamicum was generally lower than that of in E.coli.A total of 18 RBSs showed similar strength(within twofold differences)between the species in our study,and the correlation analysis of the strength of RBSs between E.coli and C.glutamicum(R^(2)=0.7483)revealed that these RBSs can be used across species.The sequence analysis revealed that the RBS region with two Ts stated was beneficial for RBS to function cross-species.The RBS characterized here can be used to precisely regulate gene expression in both hosts,and the characteristics of cross-species RBSs provide basic information for RBS rational design. | Yanting Duan Xiaojuan Zhang Weiji Zhai Jinpeng Zhang Jiawei Ren Xiaomei Zhang Guoqiang Xu Jinsong Shi Zhenghong Xu | 2022 | Systems Microbiology and Biomanufacturing2022，2，4： | 0 |
| 12 | Dual-labeled visual tracer system for topical drug delivery by nanoparticle-triggered P-glycoprotein silencing显示文摘Using nanoparticle-based drug delivery systems as enhancers is a robust strategy for transdermal delivery;however, the mechanisms by which these systems promote transdermal penetration are still unclear.Here, we fabricated a dual-labeled nano drug delivery system that allows discrete visualization of both the drug and the nanoparticle carrier. To comprehensively examine its potential mechanism, we investigated its effects on human epidermal keratinocyte Ha Ca T cells, including changes in cell membrane potential, intracellular Ca;concentration, and Ca;-ATPase activity. P-glycoprotein(P-gp) expression in nanoparticle-treated human dermal microvascular endothelial cells was detected by western blotting and immunofluorescence. Furthermore, the transdermal absorption and biodistribution of the dual-labeled nanoparticles were deeply investigated by skin permeability study in vitro and in vivo using fluorescence microscopy and in vivo imaging, respectively. In addition to reducing membrane potential, increasing the intracellular Ca;concentration, and decreasing Ca;-ATPase activity, our results indicate that the duallabeled nanoparticles can downregulate P-gp to promote transdermal absorption. Fluorescence and in vivo imaging visually demonstrated that the nanoparticle delivery system penetrated into the dermis through the stratum corneum. All these results indicate that this dual-labeled nano delivery system provides a new method for future in-depth visual explorations of transdermal drug delivery mechanisms. | Jushan Gao Shanbo Ma Xinxin Zhao Jinpeng Wen Datao Hu Xiaoye Zhao Xiaopeng Shi Ke Wang | 2021 | Chinese Chemical Letters2021，32，12： | 0 |
| 13 | Layer-by-layer epitaxy of multi-layer MoS_(2) wafers显示文摘The 2D semiconductor of MoShas great potential for advanced electronics technologies beyond silicon.So far,high-quality monolayer MoSwafers have been available and various demonstrations from individual transistors to integrated circuits have also been shown.In addition to the monolayer,multilayers have narrower band gaps but improved carrier mobilities and current capacities over the monolayer.However,achieving high-quality multi-layer MoSwafers remains a challenge.Here we report the growth of high-quality multi-layer Mo S_(2) 4-inch wafers via the layer-by-layer epitaxy process.The epitaxy leads to well-defined stacking orders between adjacent epitaxial layers and offers a delicate control of layer numbers up to six.Systematic evaluations on the atomic structures and electronic properties were carried out for achieved wafers with different layer numbers.Significant improvements in device performances were found in thicker-layer field-effect transistors(FETs),as expected.For example,the average field-effect mobility(μFE)at room temperature(RT)can increase from~80 cm·V·sfor monolayers to~110/145 cm·V·for bilayer/trilayer devices.The highest RTμFEof 234.7 cm·V·sand record-high on-current densities of 1.70 m A·μmat Vds=2V were also achieved in trilayer MoSFETs with a high on/off ratio of>107.Our work hence moves a step closer to practical applications of 2D MoSin electronics. | Qinqin Wang Jian Tang Xiaomei Li Jinpeng Tian Jing Liang Na Li Depeng Ji Lede Xian Yutuo Guo Lu Li Qinghua Zhang Yanbang Chu Zheng Wei Yanchong Zhao Luojun Du Hua Yu Xuedong Bai Lin Gu Kaihui Liu Wei Yang Rong Yang Dongxia Shi Guangyu Zhang | 2022 | National Science Review2022，9，6： | 0 |
| 14 | Real- and momentum-indirect neutral and charged excitons in a multi-valley semiconductor显示文摘Excitons dominate the photonic and optoelectronic properties of a material.Although significant advancements exist in understanding various types of excitons,progress on excitons that are indirect in both real-and momentum-spaces is still limited.Here,we demonstrate the real-and momentum-indirect neutral and charged excitons(including their phonon replicas)in a multi-valley semiconductor of bilayer MoS_(2),by performing electric-field/doping-density dependent photoluminescence.Together with first-principles calculations,we uncover that the observed real-and momentum-indirect exciton involves electron/hole from K/Γvalley,solving the longstanding controversy of its momentum origin.Remarkably,the binding energy of real-and momentum-indirect charged exciton is extremely large(i.e.,~59 meV),more than twice that of real-and momentum-direct charged exciton(i.e.,~24 meV).The giant binding energy,along with the electrical tunability and long lifetime,endows real-and momentum-indirect excitons an emerging platform to study many-body physics and to illuminate developments in photonics and optoelectronics. | Zhiheng Huang Yuhui Li Tao Bo Yanchong Zhao Fanfan Wu Lu Li Yalong Yuan Yiru Ji Le Liu Jinpeng Tian Yanbang Chu Xiaozhou Zan Yalin Peng Xiuzhen Li Yangkun Zhang Kenji Watanabe Takashi Taniguchi Zhipei Sun Wei Yang Dongxia Shi Shixuan Du Luojun Du Guangyu Zhang | 2023 | National Science Open2023，2，4： | 0 |
