作者： Yan Cui Yang Yang Tie Li Yuelin Wang Science and Technology on Micro-system Laboratory Shanghai Institute of Microsystem and Information Technology Chinese Academy of Sciences Shanghai CHINA

Precision measurement of thermal conductivity at nanoscale can facilitate the study of the pursuing thermoelectric conversion efficiency. In this work, a new reliable and accurate MEMS-based device for thermal conductivity measurement of individual nanowires was developed. Overcoming the difficulties in measuring small temperature rise at nanoscale, the measurement error of temperature rise for nanomaterials was less than 0.1360%. Besides, the effect of substrate conduction, air heat conduction and radiation heat loss on testing of thermal conductivity was basically ruled out. The thermal conductivity of VO 2 (M) single crystal nanowire with diameter of 294 nm was measured to verify the reliability and accuracy of the device.

Background: Oviductus Ranae (OR) is a well-known animal-based traditional Chinese medicine and widely consumed as a nutraceutical to optimize health. However, a current in-depth understanding of OR regulating mechanisms is lacking in the field. Aim of the study: Metabolomics, proteomics, and transcriptomics, were used as a multi-omics approach to comprehensively investigate the health effects of OR in rats. Methods: Healthy rats were chosen and randomized into two groups treated with or without OR (rats+OR and rats-OR). Soaked and homogenized OR was fed to healthy rats (rats+OR) for 14 days before blood samples were collected for omics analyses. Rats in the rats-OR group were administered sterile saline instead of homogenized OR. LC-MS/MS-based targeted metabolomics including lipidomics profiling was used to survey water-soluble metabolites and organic-soluble lipids in OR and plasma samples. LC-MS-based proteomics investigated the proteins in the plasma samples, and transcriptomic analysis was performed on blood cells isolated from rats+OR and rats-OR groups. Statistical analyses including fold change (FC) and orthogonal partial least squares discrimination analysis (OPLS-DA) were done to assess the differences between the two treatment groups. Plus, pathways regarding differential metabolites including lipids, proteins, and genes were annotated through Kyoto Encyclopedia of Genes and Genomes database (KEGG), and further common pathways were searched to revealing the potential effects of OR. Results: The LC-MS/MS-based metabolomics detected 1300 metabolites in the water phase and 981 lipids in the organic phase of OR samples. In blood samples from rats, 1580 water-soluble metabolites and 1195 organic-soluble lipids were measured in the plasma. Among them, 199 differential compounds were found between rats+OR and rats-OR groups, with 97 out of 150 downregulated lipids in rats+OR (mainly TGs). Moreover, 125 of 782 proteins were differentially altered between the two

LAMMPS is one of the most popular Molecular Dynamic (MD) packages and is widely used in the field of physics, chemistry and materials simulation. Layered Materials Force Field (LMFF) is our expansion of the LAMMPS potential function based on the Tersoff potential and inter-layer potential (ILP) in LAMMPS. LMFF is designed to study layered materials such as graphene and boron hexanitride. It is universal and does not depend on any platform. We have also carried out a series of optimizations on LMFF and the optimization work is carried out on the new generation of Sunway supercomputer, called SWLMFF. Experiments show that our implementation is efficient, scalable and portable. When generic LMFF is ported to Intel Xeon Gold 6278C, $2\times$ performance improvement is achieved. For the optimized SWLMFF, the overall performance improvement is nearly $200-330\times$ compared to the original ILP and Tersoff potentials. And SWLMFF has good parallel efficiency of 95%-100% under weak scaling with 2.7 million atoms on a single process. The maximum atomic system simulated by SWLMFF is close to $2^{31}$ atoms. And nanosecond simulations in one day can be realized.

High-density neural recordings with superior spatiotemporal resolution powerfully unveil cellular-scale neural communication, showing great promise in neural science, translational medicine, and clinical applications. To achieve such, many design and fabrication innovations enhanced the electrode, chip, or both for biocompatibility improvement, electrical performance upgrade, and size miniaturization, offering several thousands of recording sites. However, an enormous gap exists along the trajectory toward billions of recording sites for brain scale resolution, posing many more design challenges. This review tries to find possible insight into mitigating the gap by discussing the latest progress in high-density electrodes and chips for neural recordings. It emphasizes the design, fabrication, bonding techniques, and in vivo performance optimization of high-density electrodes. It discusses the promising opportunities for circuit-level and architecture-level multi-channel chip design innovations. We expect that joint effort and close collaboration between high-density electrodes and chips will pave the way to high-resolution neural recording tools supporting cutting-edge neuroscience discoveries and applications.

Emerging non-volatile memory (NVM) technologies provide opportunities for the fusion of memory and storage. The fusion of memory and storage can exploit NVM's byte-addressability and achieve the large capacity data storage. However existing file systems built for traditional disk-based storage systems will not suit for the system based on fusion of memory and storage, which could not take full advantage of the performance that NVM should provide. Thus, it's necessary to redesign file system, over NVM medium. This paper attempts to achieve the fusion of memory and storage at the software level, which exploits NVM's byte-addressability and achieves the large capacity data storage. We converge the management of main memory and storage by implementing a file system called FRFS which optimized for NVM as the system software layer to manage the NVM medium. The proposed file system integrates the management of main memory and storage, which by adopting file page tables to fuse the memory and storage management. FRFS converges the indexing metadata and address mapping of file data into the persistent file page table. A file can be mapped into virtual address space at a constant time by embedding file page table into the calling process. Since the mapping has been established, applications can read or write the file in-place without page fault interrupt. Moreover, the addressing of file data can be efficiently handled by Memory Management Unit (MMU) hardware instead of traversing software routine, which shorting the file access path. Extensive experiments are performed on the Intel server. The results indicate that FRFS can achieve excellent performance and verify the feasibility about the fusion of memory and storage management. © 2019 IEEE.

Journal of micromechanics and microengineering 2020年第5期30卷

作者： Fang, Xudong Wu, Chen Zhao, Yulong Jiang, Zhuangde Rong, Weibing Feng, Zhihong Lv, Yuanjie State Key Laboratory for Manufacturing Systems Engineering International Joint Laboratory for Micro/Nano Manufacturing and Measurement Technologies Collaborative Innovation Center of Suzhou Nano Science and Technology Xi'an Jiaotong University Xi'an710049 China School of Mechanical Engineering Xi'an Jiaotong University Xi'an710049 China State Key Laboratory of Robotics and System Harbin Institute of Technology Harbin150080 China National Key Laboratory of Application Specific Integrated Circuit Hebei Semiconductor Research Institute Shijiazhuang050051 China

It has been a challenge to develop pressure sensors that can work in harsh environments. In this work, a piezoresistive n-type 4H-SiC pressure sensor is demonstrated, capable of working at 350 C under hydraulic and pneumatic pressure. The pressure measuring range of this sensor is 7 MPa and the chip dimension is 2.5 mm 2.5 mm 0.23 mm. A reliable Ti/TaSi2/Pt metal ohmic contact is used in the sensor and experimental results show that the metal combination can withstand a wide temperature range of 30 C-350 C. In order to avoid thermal stress induced by the mismatch of thermal expansion coefficients of different packaging materials when increasing temperature, a double-layer bonding scheme of cement glue and epoxy is proposed. The inner layer of the chip and the kovar alloy base are directly bonded with the epoxy, while the outer layer is wrapped with the high-temperature cement glue. Experiments confirm that this method can achieve reliable packaging with temperatures up to 350 C for 5 h. Based on the above key technologies, the sensitivity of this sensor can reach 13.2 mV V-1 kPa-1 and the test data exhibit high linearity and repeatability. Static tests prove that the sensor has good media compatibility which can operate under a hydraulic pressure load at 220 C and a barometric pressure load under 350 C. The sensor in this work can provide a reference for pressure measurements at high temperature and in complex media environments. © 2020 IOP Publishing Ltd.

Constructing hydrogels with both remarkable mechanical and self-healing properties is highly desirable for soft electronics, yet remains challenging due to conflicting demands on chemical bonds and polymer chain mobility. Herein, a highly stretchable, self-healing, and conductive gelatin methacryloyl (GelMA) hydrogel is developed by incorporating polyvinyl alcohol, N-(2-amino-2-oxoethyl)-2-propenamide, sodium tetraborate, and sodium chloride into GelMA, followed by a two-step polymerization process. The introduced novel interpenetrating networks, hierarchical hydrogen bonds (weak and strong H-bonds), and borate ester bonds (BEBs) synergistically improve the mechanical strength, and concurrently function as sacrificial bonds for energy dissipation under deformation. Moreover, the constructed reversible BEBs and weak H-bonds enable autonomous self-healing at room temperature. The resulting hydrogel achieves remarkable stretchability (≈160%), tensile strength (≈130 kPa), and self-healing efficiency (86%), surpassing previously reported GelMA hydrogels. Importantly, a self-healing GelMA hydrogel strain sensor is demonstrated, featuring a high gauge factor (≈3.28), ultra-low detection limit (0.1%), and excellent recovery of sensitivity (≈100%) and detection range (≈75%) after damage. Successful monitoring of subtle and large-scale human motions with both original and healed sensors highlights the device's durability and longevity. This study provides a promising approach for the rational design and practical application of GelMA hydrogels in wearable bioelectronics.
