| 1 | Duplex Interpenetrating-Phase FeNiZn and FeNi_(3)Heterostructure with Low-Gibbs Free Energy Interface Coupling for Highly Efficient Overall Water Splitting显示文摘The sluggish kinetics of both hydrogen evolution reaction(HER)and oxygen evolution reaction(OER)generate the large overpotential in water electrolysis and thus high-cost hydrogen production.Here,multidimensional nanoporous interpenetrating-phase FeNiZn alloy and FeNi_(3)intermetallic heterostructure is in situ constructed on NiFe foam(FeNiZn/FeNi_(3)@NiFe)by dealloying protocol.Coupling with the eminent synergism among specific constituents and the highly efficient mass transport from integrated porous backbone,FeNiZn/FeNi_(3)@NiFe depicts exceptional bifunctional activities for water splitting with extremely low overpotentials toward OER and HER(η_(1000)=367/245 mV)as well as the robust durability during the 400 h testing in alkaline solution.The as-built water electrolyzer with FeNiZn/FeNi_(3)@NiFe as both anode and cathode exhibits record-high performances for sustainable hydrogen output in terms of much lower cell voltage of 1.759 and 1.919 V to deliver the current density of 500 and 1000 mA cm^(-2)as well long working lives.Density functional theory calculations disclose that the interface interaction between FeNiZn alloy and FeNi_(3)intermetallic generates the modulated electron structure state and optimized intermediate chemisorption,thus diminishing the energy barriers for hydrogen production in water splitting.With the merits of fine performances,scalable fabrication,and low cost,FeNiZn/FeNi_(3)@NiFe holds prospective application potential as the bifunctional electrocatalyst for water splitting. | Qiuxia Zhou Caixia Xu Jiagang Hou Wenqing Ma Tianzhen Jian Shishen Yan Hong Liu | 2023 | Nano-Micro Letters2023，15，7： | 1 |
| 2 | Enhanced Beta2-band Oscillations Denote Auditory Hallucination in Schizophrenia Patients and a Monkey Model of Psychosis显示文摘An electroencephalographic(EEG)signature of auditory hallucinations(AHs)is important for facilitating the diagnosis and treatment of AHs in schizophrenia.We recorded EEG from 25 schizophrenia patients with recurrent AHs.During the period of AHs,EEG recordings exhibited significantly elevated beta2-band power in the temporal region,as compared to those recorded in the absence of AHs or during stimulation with verbal sounds.We further generated methamphetamine-treated rhesus monkeys exhibiting psychosis-like behaviors,including repetitive sudden searching actions in the absence of external intrusion,suggesting the occurrence of AHs.Epidural EEG beta2-band power in the temporal region of these monkeys was enhanced immediately after methamphetamine treatment and positively correlated with the frequency of sudden searching actions.Thus,the enhancement of temporal beta2-band oscillations represents a signature for AHs in both patients and a monkey model of psychosis,and this monkey model can be used for developing closed-loop neuromodulation approaches for the treatment of refractory AHs in schizophrenia. | Shuo Ma Tianzhen Chen Wenjun Jia Jie Liu Shihan Ding Puzhe Li Hong Gan Dapeng Zhang Shuxin Shao Mu-Ming Poo Min Zhao Bomin Sun Jian Jiang | 2024 | Neuroscience Bulletin2024，40，3： | 0 |
| 3 | Intermetallic-driven highly reversible electrocatalysis in Li–CO_(2) battery over nanoporous Ni_(3)Al/Ni heterostructure显示文摘Li–CO_(2) batteries,which integrate CO_(2) utilization and electrochemical energy storage,offer the prospect of utilizing a greenhouse gas and providing an alternative to the well-established lithium-ion batteries.However,they still suffer from rather limited reversibility,low energy efficiency,and sluggish CO_(2) redox reaction kinetics.To address these key issues,a nanoporous Ni_(3)Al intermetallic/Ni heterojunction(NP–Ni_(3) Al/Ni)is purposely engi-neered here via an alloying–etching protocol,whereby the unique interactions between Al and Ni in Ni_(3)Al endow NP-Ni_(3)Al/Ni with optimum reactant/product adsorption and thus unique catalytic performance for the CO_(2) redox reaction.Furthermore,the nanoporous spongy structure benefits mass transport as well as discharge product storage and enables a rich multiphase reaction interface.In situ Raman studies and theoretical simulations reveal that both CO_(2) reduction and the co-decomposition of Li_(2)CO_(3) and C are distinctly promoted by NP-Ni_(3)Al/Ni,thereby greatly improving catalytic activity and stability.NP-Ni_(3)Al/Ni offers promising application potential in Li–CO_(2) batteries,with its scalable fabrication,low production cost,and superior catalytic performance. | Tianzhen Jian Wenqing Ma Caixia Xu Hong Liu John Wang | 2023 | eScience2023，3，3： | 0 |
