| 1 | CaMKIIα-driven,phosphatase-checked postsynaptic plasticity via phase separation显示文摘Ca^(2+)/calmodulin-dependent kinase Ila(CaMKIla)is essential for synaptic plasticity and learning by decoding synaptic Ca^(2+)oscillations.Despite decades of extensive research,new mechanisms underlying CaMKIIa's function in synapses are still being discovered.Here,we discover that Shank3 is a specific binding partner for autoinhibited CaMKIla.We demonstrate that Shank3 and GluN2B,via combined actions of Ca^(2+)and phosphatases,reciprocally bind to CaMKIla.Under basal condition,CaMKIla is recruited to the Shank3 subcompartment of postsynaptic density(PSD)via phase separation.Rise of Ca^(2+)concentration induces GluN2Bmediated recruitment of active CaMKIla and formation of the CaMKIIa/GluN2B/PSD-95 condensates,which are autonomously dispersed upon Ca^(2+)removal.Protein phosphatases control the Ca^(2+)-dependent shuttling of CaMKIla between the two PSD subcompartme nts and PSD condensate formation.Activation of CaMKIla further enlarges the PSD assembly and in duces structural LTP.Thus,Ca^(2+)-induced and phosphatase-checked shuttling of CaMKIla between distinct PSD nano-domains can regulate phase separation-mediated PSD assembly and synaptic plasticity. | Qixu Caic Menglong Zeng Xiandeng Wu Haowei Wu Yumeng Zhan Ruijun Tian Mingjie Zhang | 2021 | Cell Research2021，31，1： | 3 |
| 2 | One-step synthesis of monodispersed Pt nanoparticles anchored on 3D graphene foams and its application for electrocatalytic hydrogen evolution显示文摘Although platinum-based materials are regarded as the state-of-the-art electro-catalysts for hydrogen evolution reaction(HER),high cost and quantity scarcity hamper their scale-up utilization in industrial deployment.Herein,a one-step strategy was developed to synthesize multi-walled carbon nanotubes and reduced graphene oxide supported Pt nanoparticle hydrogel(PtNP/rGO-MWCNT),in which only ascorbic acid was used as the reductant for one-pot reduction of both GO and chloroplatinic acid.The hydrogel can be directly used as a flexible binder-free catalytic electrode to achieve high performance of HER.Compared to conventional strategies,the current strategy not only significantly reduces the Pt loading to 3.48 wt%,simplifies the synthesis process,but also eliminates the use of any polymer binders,thus decreasing the series resistance and improving catalytic activity.An overpotential of only 11 mV was achieved on as-prepared PtNP/rGO-MWCNT to drive a geometrical current density of 10 mA/cm2 in0.5 mol/L H2 SO4,with its catalytic activity being kept over 15 h.In acidic medium,the HER activity of the PtNP/rGO-MWCNT catalyst exceeds most of the reported Pt-based electro-catalysts and is 3-fold higher than that obtained on commercial Pt/C electrode. | Dan Zhou Bei Jiang Rui Yang Xiandeng Hou Chengbin Zheng | 2020 | Chinese Chemical Letters2020，31，6： | 3 |

| 11 | BER ANALYSIS OF A GMSK SYSTEM USING DECISION FEEDBACK显示文摘There are considerable literatures on the Bit Error Rate(BER)evaluation of DifferentialDetection of Gaussian Minimum Shift Keying(DDGMSK)system using Decision Feedback(DF),butmost of them give the performance based on the Monte Carlo Error Counting(MCEC)technique.Fromthe probability distribution of the phase angle between two vectors perturbed by Gaussian noises,theformulae of BER are derived for the performance analysis of DDGMSK system with DF in this letter.Considering the m-bit dock-tailed sequence,the new formulae of Gaussian Minimum Shift Keying(GMSK)modulated phase and the Time-Varying Signal to Noise Ratio(TVSNR)of the demodulatedsignal are presented,and it is proved that the relationship between the TVSNR of the demodulatedsignal and the size of eye opening is not inevitable.Simulation results show that the theoretical in-vestigation gives analogous results with the MCEC technique.The formulae presented are useful for theperformance analysis of systems using GMSK as modulating and demodulating method,for instance,the analysis of synchronous performance of frequency-hopping communication system. | He Xiandeng Pei Changxing | 2008 | Journal of Electronics(China)2008，25，4： | 1 |
| 12 | Facile electrochemical synthesis of nano iron porous coordination polymer using scrap iron for simultaneous and cost-effective removal of organic and inorganic arsenic显示文摘Although large amounts of engineered nanomaterials have been used for the arsenic removal, today there still remains several serious impediments to its further application, including consumption of expensive and pure salts, and only application for the removal of inorganic arsenic. In this work, we developed an eco-economic and facile electrochemical method to synthesize iron porous coordination polymers(FePCPs) for the simultaneous removal of inorganic and organic arsenic from natural water. | Mengni Zhang Jia Jia Ke Huang Xiandeng Hou Chengbin Zheng | 2018 | Chinese Chemical Letters2018，29，3： | 1 |

| 16 | Reduction of mercury(Ⅱ)by electrons contained in carbon dots:An environmentally friendly cold vapor generation for mercury analysis显示文摘In this work,the reduction of mercury ions(Hg2+)to elemental mercury(Hg0)was easily achieved using highly reductive carbon dots(r-CDs),which synthesized from sucrose by a simple and cost-effective method.After a careful mechanistic study,the reduction was probably accomplished with the large numbers of electrons contained in r-CDs rather than the oxidation of its functional groups.Additionally,a3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT)assay showed that the r-CDs were nontoxic to wildlife and human beings.Consequently,the r-CDs were used as an alternative to toxic reductants(SnCl2 or NaBH4)for the sensitive and in situ determination of mercury by cold vapor gene ration(CVG)coupled to a miniature point discharge optical emission spectrometer(μPD-OES).Limit of detection of 0.05μg/L was obtained for Hg2+,with relative standard deviation(RSD)less than 5.4%at a concentration of 5μg/L.The accuracy of r-CDs induced CVG-μPD-OES was validated by the determination of mercury in a certified reference material(DOLT-5,dogfish liver)and five natural water samples collected from different rivers and lakes in Chengdu City,Since r-CDs are nontoxic and prepared from abundant and inexpensive sucrose,the r-CDs induced CVG-μPD-OES retains the great potential for the inexpensive and enviro nmentally friendly field analysis of mercury in natural water.The accuracy of the proposed method was validated by the analysis of a certified reference material and several water samples with satisfactory results. | Tao Chen Yao Lin Haochen Li Rui Yang Xiandeng Hou Baozhan Zheng Chengbin Zheng | 2020 | Chinese Chemical Letters2020，31，10： | 0 |

| 18 | Simultaneous extraction of level 2 and level 3 characteristics from latent fingerprints imaged with quantum dots for improved fingerprint analysis显示文摘Fingerprints are unique and life-long to everyone, so they occupy very important statuses in forensic science. However, due to the limit of current imaging technologies and instruments, recognition and matching of fingerprints are mostly based on their level 2 structures(bifurcation, crossover, and etc.).Moreover, in real-world cases, fingerprints collected in the field are often incomplete or damaged, which adds further difficulty in fingerprint analysis. Quantum dots(QDs) are superior fluorescent imaging agents for latent fingerprints, which can provide both level 2 and level 3(sweat pores) details. Here, we used red-emitting N-acetylcysteine-capped Cd Te QDs as imaging agent for staining of eccrine LFPs. The numbers of level 2 and level 3 features that can be mapped are significantly larger than those obtained by cyanoacrylate fuming, a standard technique being adopted at forensic scene. Therefore, the level 2 and level 3 characteristics from QD-staining were simultaneously extracted for improved fingerprint analysis.A preliminary fingerprint matching based modified Pore Matching algorithm was thus developed based on the integration of both level 2 and level 3 characteristics. Satisfactory results of fingerprint matching were obtained, demonstrating the advantage of the QD-staining for advanced fingerprint analysis. | Yuqin Li Chaoying Xu Chang Shu Xiandeng Hou Peng Wu | 2017 | Chinese Chemical Letters2017，28，10： | 0 |
