We describe in this paper the fabrication of two- and one-dimensional nanostructures with organic molecular beam epitaxy （OMBE） principle based on controlled selfassembly by using adsorbate-substrate and intennolecular interactions that are important in molecular fabrication. Cu（100） single crystal was used as substrate in fabricating molecular nanostructures. Scanning tunneling microscopy （STM） experiments confirmed that Zn-tetra- [3,5-di-t-butylphenyl]porphyrin-molecules can be used to fabricate both monolayer and molecular wire on Cu（100） surface simultaneously, and the latter is arranged on the terrace edges. We herein briefly discuss the selectivity in terms of a mechanism in which the highest occupied and lowest unoccupied molecular orbitals （HOMO and LUMO） of the molecules interact with the surface.

With intriguing structures and potential applications in the fields of photoluminescence,catalysis,molecular magnet,and so on,coordination polymers(CPs) have continuously attracted widespread attention over the past several decades.[1-2]For constructions of CPs with neutral organic ligands,the anions associated with the metal ions will inevitably be incorporated into the framework to balance the charges of the whole CP *** may act as terminal ligands to occupy some of the coordination sites,or may serve as versatile linkers to connect metal ions into more complicated structural units such as metal clusters,thereby producing new coordination polymers[3].In this context,it is necessary to investigate the correlation between the anion and structure,which is beneficial to interpret the law of self-assemble in coordination polymers and create new desired CP ***,we designed a new amide ligand,N,N’-di(3-pyridine)oxamide ligand(DPOM) and reported the crystal structures and luminescent properties of four coordination polymers with DPOM,including two one-dimensional(1 D) chain/ladder polymers,[Ni(DPOM)(H O)]SO·2 H O(1) and[Cd(DPOM)(NO)](2),as well as two 3 D coordination polymers,[Zn(DPOM)(H O)(SO)](3) and[Cd(DPOM)(H O)(SO)](4).

碳化硅(SiC)金属-氧化物半导体场效应管(MOSFET)以其优良的性能得到广泛关注,结温是一个关键指标,用于健康状况监测。这里基于状态监控的需要,提出一种开通瞬态漏极电流变化率(di_(ds)/dt)结温提取的方法,首先从理论层面分析了di_(ds)/dt温度相关性,并用实验表明了di_(ds)/dt随着器件结温增加而增加,然后又对影响di_(ds)/dt的因素进行了分析,在双脉冲实验中证实了di_(ds)/dt的温度敏感度随负载电流和外部栅极电阻增加而增加,该方法在大驱动电阻下有更好的温度敏感度但也增加了开关损耗,牺牲了开关频率,基于此提出一种智能驱动器的方法,在不增加开关损耗的前提下有效测量SiC MOSFET的结温。

Methane, an abundant one-carbon（C1） resource, is extensively used in the industrial production of vital fuels and value-added chemicals. However, current industrial methane conversion technologies are energy-and carbon-intensive, mainly due to the high activation energy required to break the inert C–H bond, low selectivity, and problematic side reactions, including CO2emissions and coke deposition. Electrochemical conversion of methane（ECM） using intermittent renewable energy offers an attractive solution, due to its modular reactor design and operational flexibility across a broad spectrum of temperatures and pressures. This review emphasizes conversion pathways of methane in various reaction systems, highlighting the significance and advantages of ECM in facilitating a sustainable artificial carbon cycle. This work provides a comprehensive overview of conventional methane activation mechanisms and delineates the complete pathways of methane conversion in electrolysis contexts. Based on surface/interface chemistry, this work systematically analyzes proposed reaction pathways and corresponding strategies to enhance ECM efficiency towards various target products, including syngas, hydrocarbons, oxygenates, and advanced carbon materials. The discussion also encompasses opportunities and challenges for the ECM process, including insights into ECM pathways, rational electrocatalyst design, establishment of benchmarking protocols, electrolyte engineering, enhancement of CH4conversion rates, and minimization of CO2emission.
