Surgical robots are designed to provide enhanced precision and dexterity compared to manual surgical procedures,which mainly rely on multimodal sensing technologies for the surgeon to seamlessly operate the robotic arms and *** with single-mode sensors, optical and mechanical bi-modal sensors provide improved precision, enhanced safety,and robustness of human-machine interaction systems. Here, the template-guided and pneumatic printing technologies are combined to construct perovskite and graphene parallel structures with both optical and mechanical sensing capabilities. The printed uniformly crystallized perovskite microstructure exhibits fast and sensitive photoelectric response characteristics,enabling shadow recognition functionality. The combination of graphene and elastic rubber endows the great printability to prepare parallel structures near the perovskite arrays for force sensing capabilities. Thus, the printed perovskite and graphene structures possess non-contact optical sensing capabilities to detect hand position by recognizing shadows between the hand and the sensor, as well as contact mechanical sensing capabilities to detect touch force applied by the hand. It provides a synergistic platform for real-time and multidimensional feedback to improve human-machine interaction.

探讨300℃,反应时间10 h,浓度20~30 g/L下,棉在苯酚作用下的碳化形态。结果表明,棉纤维在不加催化剂下可实现碳化,但是形貌比较差;加入苯酚后依然不能形成球,而且形貌有所下降;葡萄糖加入苯酚后,也没有形成球,对产量的影响也在误差范围内。所以,苯酚对棉和葡萄糖的碳化几乎没影响。

目的探讨荞麦花叶芦丁(RBFL)对肝细胞损伤的保护作用,并探讨其可能机制。方法从荞麦花和叶中提取RBFL。采用胰蛋白酶消化、分离小鼠肝细胞行原代培养,乙醇体外诱导肝细胞损伤,以不同浓度的RBFL干预。检测损伤肝细胞培养上清液中天门冬氨酸氨基转换酶(AST)、丙氨酸氨基转移酶(ALT)、超氧化物歧化酶(SOD)活性和丙二醛(MDA)水平。结果与正常对照组比较,模型组AST、ALT、MDA明显升高,SOD活性明显降低(P均<0.01)。与模型组比较,RBFL75～300 mg/L干预后AST、ALT、MDA水平明显降低,SOD活性明显提高,呈剂量依赖性,P<0.05、<0.01。结论 RBFL对乙醇所致的肝细胞损伤有明显保护作用;其机制可能与RBFL能清除自由基、防止脂质过氧化、改善脂质代谢有关。

Optoelectronics Letters 2025年

作者： zhang Ailing WANG bo zhang Yongfu CHANG Pengxiang WANG Minghe LIN Rui Engineering Research Center of Optoelectronic Devices & Communication Technology， Ministry of Education， Tianjin Key Laboratory of Film Electronic and Communication Devices， School of Electrical and Electronic Engineering， Tianjin University of Technology

A crosstalk-free multichannel sensor based on a dual-Sagnac interferometer interrogated by microwave photonic filter (MPF) is demonstrated theoretically and experimentally in this paper. The dual-Sagnac interferometer is taken as the sensing element as well as an optical spectrum slicer to implement a dual-passband MPF. Experimental results show that the proposed multichannel sensor is crosstalk-free， and the temperature sensitivity of each channel is -0.9884 MHz/℃ and -1.9302 MHz/℃， respectively. The sensing interrogation system has good linearity and stability and it is suitable for application scenarios where multiple points of temperature are required to monitor simultaneously.

Resolving the developmental mechanisms of cardiac microthrombosis of SARS-CoV-2 based on single-cell transcriptome analysis

The coronavirus disease 2019（COVID-19） outbreak caused by the severe acute respiratory syndrome coronavirus-2（SARS-CoV-2） developed into a global health emergency. Systemic microthrombus caused by SARS-CoV-2 infection is a common complication in patients with COVID-19. Cardiac microthrombosis as a complication of SARS-CoV-2 infection is the primary cause of cardiac injury and death in patietns with severe COVID-19. In this study, we performed single-cell sequencing analysis of the right ventricular free wall tissue from healthy donors,patients who died during the hypercoagulable period of characteristic coagulation abnormality（CAC）, and patients who died during the fibrinolytic period of CAC. We collected 61,187 cells enriched in 24 immune cell subsets and 13 cardiac-resident cell subsets. We found that in the course of SARS-CoV-2 infected heart microthrombus, MYO1EhighRASGEF1Bhighmonocyte-derived macrophages promoted hyperactivation of the immune system and initiated the extrinsic coagulation pathway by activating chemokines CCL3, CCL5. This series of events is the main cause of cardiac microthrombi following SARS-CoV-2 infection. In a SARS-CoV-2 infected heart microthrombus, excessive immune activation is accompanied by an increase in cellular iron content, which in turn promotes oxidative stress and intensifies intercellular competition. This induces cells to alter their metabolic environment, resulting in increased sugar uptake via the glycosaminoglycan synthesis pathway. In addition, high levels of reactive oxygen species generated by elevated iron levels promote increased endogenous malondialdehyde synthesis in a subpopulation of cardiac endothelial cells. This exacerbates endothelial cell dysfunction and exacerbates the coagulopathy process.

In inverted perovskite solar cells (PSCs),effective modification of the interface between the metalcathode and electron transport layer (ETL) is crucial forachieving high performance and stability. Herein, sulfonatedbathocuproine, commonly known as disodium bathocuproinedisulfonate (BCDS), was employed as a cathode buffer layerto address the interfacial issues at the [6,6]-phenyl-C61-butyricacid methyl ester (PCBM)/Ag interface. BCDS possesses theability to form coordinate bonds with Ag electrodes. Theutilization of the BCDS buffer layer enhanced the chargeextraction capability at the cathode interface whilesimultaneously achieving interfacial defect passivation,improving interfacial contact and increasing the built-in electricfield. Consequently, a power conversion efficiency (PCE) of25.06% was achieved. Furthermore, owing to the excellent filmforminguniformity of BCDS on PCBM, the stability of thedevice was also improved. After storage in dry air for morethan 2000 h, the device maintained 96% of its initial efficiency. This work underscores the remarkable potential of tailoringcoordination groups to enhance charge extraction efficiency at the ETL-cathode interface, unveiling a promising newfrontier in buffer layer development and performance optimization strategies for PSCs.
