A double acid corrosion and subsequent hydrothermal treatment were used to fabricate a micro–nano-structured Ti substrates(Ti–M–N).Afterward,the mesoporous polydopamine(MPDA)nanoparticles as photothermal agent were prepared and immobilized on the surface of Ti–M–N samples,in order to obtain Ti–M–NMPDA *** micro–nanostructure properties and the photothermal effect of the modified Ti implant caused physical stress on the bacteria and the bacterial membrane damage,and eventually led to bacteria *** importantly,based on excellent bioactivity and cytocompatibility of mussel-inspired materials,MPDA promoted adhesion,proliferation and osteogenic differentiation of mesenchymal stem cells in ***,animal experiments in vivo further confirmed that the modified Ti implants could enhance osseointegration.

Magnetic tunnel junctions with ferroelectric barriers, often referred to as multiferroic tunnel junc- tions, have been proposed recently to display new functionalities and new device concepts. One of the notable predictions is that the combination of two charge polarizing states and the parallel and antiparallel magnetic states could make it a four resistance state device. We have recently studied the ferroelectric tunneling using a scanning probe technique and multiferroic tunnel junctions using ferromagnetic Lao.7Cao.3MnO3 and ***.3MnO3 as the electrodes and ferroelectric （Ba, Sr）TiO3 as the barrier in trilayer planner junctions. We show that very thin （Ba, Sr）TiO3 films can sustain ferroelectricity up till room temperature. The multiferroic tunnel junctions show four resistance states as predicted and can operate at room temperatures.

青光眼是全球第一大不可逆致盲性眼病,是一组以特征性视神经损伤和视野缺损为共同特征的神经眼科疾病。已有多项研究表明,青光眼的损害不仅局限于眼球局部视神经节细胞的凋亡,而且会累及大脑视皮层整个视觉通路,是一种全脑神经退行性疾病。近年来,功能性磁共振成像(functional magnetic resonance imaging,fMRI)技术飞速发展,将神经系统的解剖和功能相结合,使局部脑组织的损伤与脑功能的缺失对应起来,可以实现在无创条件下观察中枢神经系统解剖结构及功能变化,为青光眼病理机制的研究提供了有效证据。而静息态功能磁共振成像(resting-state functional magnetic resonance imaging,rs-fMRI)作为神经影像学的热点研究技术,为探讨青光眼患者视觉相关脑区的解剖结构、代谢以及功能改变提供了影像学支持。本综述主要讨论了rs-fMRI的基本原理以及低频振幅(amplitude of low-frequency fluctuation,ALFF)、局部一致性(regional homogeneity,ReHo)、度中心度(degree centrality,DC)、功能连接(functional connectivity,FC)等几种较为常用的分析方法在青光眼中应用的研究进展。

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.
