Ru-based materials are promising electrocatalysts for hydrogen evolution reaction (HER) owing to their low-cost (one twenty-fifth of Pt) and similar Gibbs free energy of H* adsorption (AGH*) to that of Pt. However, the inadequate ability for the water dissociation of Ru catalysts is significantly impeding the water splitting efficiency. In this work, we demonstrate an atomically ordered hexagonal Ru-Ni alloy with compressive-strained Ru skin as a high-performance HER catalyst for significantly boosting the water dissociation. The Ordered Ru-Ni achieves an optimized catalytic activity for alkaline HER with a low overpotential of 23 mV at 10 mA cm-2, Tafel slope of 25.9 mV dec-1 and superior mass activity of 4.83 A mg-Ru1, which is 15.1 times higher than Ru/C. According to DFT calculations, the ordered RuNi core imposes homogeneous compressive strain on the Ru skin, resulting in an optimum binding energy towards H*/OH* intermediates on Ru active sites for rapid Tafel step kinetics. Moreover, the decreased H2O dissociation energy barrier of Ordered Ru-Ni suggests a promoted VolmerTafel kinetics is achieved, significantly boosting the overall HER efficiency. This work provides a practical avenue for surface strain engineering of Ru-based catalysts to promote the HER activity.

The study aimed to quantitatively assess functional risks in the medication administration process of elderly inpatients and develop management measures from a holistic system safety perspective. The functional resonance analysis method and decision-making trial and evaluation laboratory (DEMATEL) method were introduced to graphically model the medication administration process in elderly inpatients and identify safety issues affecting the complex interactions of functions. Semi-structured interviews based on the Fit between Individual, task, technology, and environment framework were used to explore medication safety management measures. A total of 18 functional modules were included in the medication process model for elderly inpatients. The DEMATEL results showed that medical order entry accounted for the highest proportion of the medication process, followed by label printing. Patient identification and drug verification, as downstream links, showed high impacts and influence. Among the safety management measures, task-technology fit and technology-individual fit were the most common. In the future, more research on medication management in elderly patients with different levels of care, settings and contexts, such as home and community, is needed. Attention should be paid to the integration and effect of implementing management measures to comprehensively safeguard patient medication safety.

Pyrolysis utilizes biomass to produce a liquid product bio-oil which is widely used as a potential energy source and a low-cost feedstock for chemical production. Considerable efforts have been made to convert biomass to bio-oil since the oil crisis in mid-1970s. This review focuses on the recent developments in catalysts used in pyrlysis of biomass for bio-oil production. In this review, 5 types of catalysts such as metal oxide, molecular sieve, mineral, transition metal and others, have been given. Molecular sieves, such as HZSM-5, ZSM-5, MCM-41, SBA-15, HUSY, REY and their modified catalysts are most widely used in biomass catalytic pyrolysis process. The effects of catalysts on bio-oil yields, quality, composition, stability etc. are also discussed. Although catalysts in pyrolysis of biomass produce markedly influences on bio-oil products, the variety of catalyst types and properties make generalizations difficult to define, in regard to trying to critically analyze the literature. © 2011 IEEE.

作者： Ding Sheng jiang Quanjiang Liang xuwen Shanghai Engineering Center for Microsatellites Shanghai 200050 China Shanghai Institute of Microsystem and Information Technology Chinese Academy of Sciences Shanghai 200050 China

As a novel rapid acquisition scheme, the partial correlation with frequency sweeping (PC-FS) method is proposed for acquisition of direct-sequence spread-spectrum (DSSS) signal in the presence of Doppler shift. The output performance of the PC-FS scheme is analyzed and a hardware structure which can largely accelerate the synchronization process is designed. Application results show that new acquisition scheme can provide a significant improvement in flexibility and efficiency over the PMF-FFT method.

Xanthomonas oryzae pv. oryzae (Xoo) infection directly leads to a severe disease known as leaf blight, which is a major cause of yield loss of rice. Use of traditional bactericides has resulted in severe resistance in pathogenic bacteria. A new approach screening compounds that target the virulence factors rather than killing bacterial pathogens is imperative. In gram-negative bacteria, the type III secretion system (T3SS) is a conserved and significant virulence factor considered as a target for drug development. Therefore, we designed and synthesized a new series of 5-phenyl-2-furan carboxylic acid derivatives stitched with 2-mercapto-1,3,4-thiadiazole. Bioassays revealed that the title candidates attenuated the hypersensitive response through suppressing the promoter activity of a harpin gene hpa1 without affecting bacterial growth. Quantitative real time polymerase chain reaction (qRT-PCR) analysis demonstrated reduced the expression of several genes associated with T3SS, when title compounds were applied. Additionally, hrp gene cluster members, including hrpG and hrpX, had reduced mRNA levels. In vivo greenhouse tests showed that candidate compounds could alleviate the effects of Xoo infection in rice (Oryza sativa) and possess better protective activity against rice bacterial leaf blight than bismerthiazol and thiodiazole copper. All tested compounds were safe to rice. This work suggests there are new safe options for Xoo control in rice from these 1,3,4-thiadiazole derivatives.

Nowadays, most of the 10 kV distribution network cable lines are laid underground in the form of direct burial or casing, and the cable is cut off by the construction machinery, resulting in the accident of line tripping. In the construction of urban construction, third-party external forces such as manual excavation, mechanical excavation and illegal invasion will cause serious damage to underground cables. Therefore, it is of great engineering application value to develop cable marking piles with sound source localization function and find the location of damage points in time. In order to improve the accuracy and effectiveness of positioning, but also to achieve rapid positioning of the source of damage, this paper is based on the sound sensor, using its flexibility, efficiency and timeliness, by controlling the number and location of the sound sensor, combined with the sound intensity to locate the sound source. At the same time, the sound sensor is connected with the number and position of the marking pile, and the traditional cable marking pile is improved to accurately locate the damage source in time. © 2024 SPIE.

Background and aims The crude extract of the endophyte Paecilomyces variotii known as ZhiNengCong (ZNC) has function of promoting plant growth and enhancing disease resistance and is widely used in China. Our study aims to evaluate the molecular mechanisms of plant growth promotion and disease protection. Methods We generated transcriptome profiles from ZNC-treated seedlings using RNA sequencing. The function of salicylic acid (SA) in ZNC-mediated immunity was examined using SA biosynthesis and signaling pathway mutants. The concentrations of nitrogen (N) and phosphorus (P) in seedlings under ZNC treatment were measured. The effect of ZNC on the level of the hormone auxin in roots was tested using transgenic plants containing DR5::GFP. Results ZNC exhibited ultrahigh activity in promoting plant growth and enhancing disease resistance, even at concentrations as low as 1-10 ng/ml. ZNC induced ROS accumulation, callose deposition, and expression of PR genes. SA biosynthesis and signaling pathways were required for the ZNC-mediated defense response. Moreover, in improving plant growth, ZNC increased the level of auxin in root tips and regulated the absorption of N and P. Conclusion According to these results, ZNC is a highly effective plant elicitor that promotes plant growth by inducing auxin accumulation at the root tip at low concentrations and enhances plant disease resistance by activating the SA signaling pathway at high concentrations.

Decentralized peer-to-peer Local Energy Markets (LEMs) are gaining popularity as local power production from Renewable Energy Sources (RESs) increases. The study investigates a blockchain-driven LEM in which prosumers and consumers buy and sell energy independently of the involvement of a third party. The suggested scheme involves Home Energy Management (HEM) and demurrage mechanisms that enable both consumers and prosumers to reduce their power prices and improve their power usage. The end-user can likewise move the load to off-peak periods and benefit from lower energy costs from the LEM through the approach. In this solution, HEM and demurrage mechanisms are used to optimize power usage as well as energy costs. As well as providing adequate power for the LEM, it is economically beneficial for end users and the community. The proposed system in the study utilizes the Deep Deterministic Policy Gradient (DDPG) algorithm and demurrage mechanisms to optimize electricity usage and energy costs. Meanwhile, smart contract on the Ethereum blockchain regulate and safeguard the electricity trading process. © 2024 IEEE.
