Solar-to-chemical energy conversion under weak solar irradiation is generally difficult to meet the heat demand of CO 2 reduction. Herein, a new concentrated solar-driven photothermal system coupling a dual-metal single-atom catalyst (DSAC) with adjacent Ni−N 4 and Fe−N 4 pair sites is designed for boosting gas-solid CO 2 reduction with H 2 O under simulated solar irradiation, even under ambient sunlight. As expected, the (Ni, Fe)−N−C DSAC exhibits a superior photothermal catalytic performance for CO 2 reduction to CO (86.16 μmol g −1 h −1 ), CH 4 (135.35 μmol g −1 h −1 ) and CH 3 OH (59.81 μmol g −1 h −1 ), which are equivalent to 1.70-fold, 1.27-fold and 1.23-fold higher than those of the Fe−N−C catalyst, respectively. Based on theoretical simulations, the Fermi level and d-band center of Fe atom is efficiently regulated in non-interacting Ni and Fe dual-atom pair sites with electronic interaction through electron orbital hybridization on (Ni, Fe)−N−C DSAC. Crucially, the distance between adjacent Ni and Fe atoms of the Ni−N−N−Fe configuration means that the additional Ni atom as a new active site contributes to the main *COOH and *HCO 3 dissociation to optimize the corresponding energy barriers in the reaction process, leading to specific dual reaction pathways (COOH and HCO 3 pathways) for solar-driven photothermal CO 2 reduction to initial CO production.

High performance under low supply voltage is required for ULSIs in combination with the higher packing density that results from scaling down to the deep sub-micron region. For this requirement, the conventional method, using the DC hot carrier lifetime of MOSFETs as measured by DC stress, overestimates the degradation caused by real circuit operation. As a result, the improvement of MOSFET performance is limited by attempting to satisfy the overestimated hot carrier criteria under DC stress. Therefore, it is strongly desired that the reliability simulation estimate accurately hot carrier degradation in real circuit operation. We have found that the degradation rate depends on the stress conditions and can be expressed in terms of the difference between the gate and drain voltages. Hence, in this paper, we propose a new method of modeling and calculation of hot carrier degradation that incorporates this dependence and will demonstrate improved accuracy in predicting degradation and life time for both AC and DC bias conditions. We also propose a new duty ratio extraction method that can be used to predict the lifetime for hot carrier degradation under actual circuit operation.

USS Ingraham (FFG-61) is the prototype ship for NavSea's Advanced Technical Information System (ATIS). ATIS is a digital technical library, which holds on optical disks the ship's 2,000 technical manuals and 73,000 drawing sheets. It contains a detailed ship's configuration index (derived from SCLSIS) to lead the user to the proper drawing or manual, and it replaces the ship's aperture cards and the second (library) copy of the technical manuals. ATIS, and the data standards established and tested through ATIS development, will be the technical library portion of micro-SNAP and SNAP III. It also forms an important part of NavSea's plans to utilize EDMICS data. This paper describes the goals and technical concepts behind the development of ATIS. Problems encountered, solutions developed, and lessons learned are detailed. Special attention was paid to the application of the Computer Aided Acquisition and Logistic Support (CALS) standards, problems caused by conflicts and ambiguities in those standards, the standards.

One of the most common energy carriers in the petrochemical industry is water vapor, which is mainly used as a heating medium in process plants. The effective functioning of steam supply, condensate collection and return systems is one of the criteria that affect the cost of production. Improper organization of the steam supply system leads to overuse of heating steam, uneven operation of the steam system and emergency situations. This paper analyzes possible problems in steam supply systems in the absence or incorrect operation of steam traps. The specific indicators of the object of study, circuit solutions and the economic efficiency of the use of steam traps are calculated.

Integrated Soft Porosity and Electrical Properties of Conductive-on-Insulating Metal-Organic Framework Nanocrystals

引用

Angewandte Chemie 2023年第35期135卷

A one-stone, two-bird method to integrate the soft porosity and electrical properties of distinct metal–organic frameworks (MOFs) into a single material involves the design of conductive-on-insulating MOF ( c MOF-on- i MOF) heterostructures that allow for direct electrical control. Herein, we report the synthesis of c MOF-on- i MOF heterostructures using a seeded layer-by-layer method, in which the sorptive i MOF core is combined with chemiresistive c MOF shells. The resulting c MOF-on- i MOF heterostructures exhibit enhanced selective sorption of CO 2 compared to the pristine i MOF (298 K, 1 bar, S from 15.4 of ZIF-7 to 43.2–152.8). This enhancement is attributed to the porous interface formed by the hybridization of both frameworks at the molecular level. Furthermore, owing to the flexible structure of the i MOF core, the c MOF-on- i MOF heterostructures with semiconductive soft porous interfaces demonstrated high flexibility in sensing and electrical “shape memory” toward acetone and CO 2 . This behavior was observed through the guest-induced structural changes of the i MOF core, as revealed by the operando synchrotron grazing incidence wide-angle X-ray scattering measurements.

He received his Associate in Engineering degree in Drafting and Design Technology in 1959 his B.S. degree in Aerospace Engineering in 1965 and his M.S. degree in Engineering Mechanics in 1970 all from Pennsylvania State University. In 1973 he was selected for the Navy's Long-Term Training Program at the University of Michigan from which he received his M.S.E. degree in Naval Architecture in 1974. Mr. Johnson began his professional career at the Ordnance Research Laboratory Pennsylvania State University in 1959 where he was involved in the design of hydroelastic submarine models and conducted research in the area of flow-induced structural vibrations. Subsequently he joined HRB-Singer at State College Pennsylvania in 1967 as a Research Engineer and in 1969 joined the former Naval Ship Engineering Center (NAVSEC) where he was employed in the Submarine Structures Branch Surface Ship Structures Branch and the Performance and Stability Branch of the Hull Division.

The recent trend in Naval Forces has been a shrinking Fleet in both numbers and ship size. This dictates that our ships must have greater operational effectiveness if the Navy is to continue to carry out its mission in the future as it has done in the past. The seakeeping performance of a ship is a major determinant of its overall operational effectiveness. The methodology presented in this paper is a comprehensive approach to the evaluation of a ship's seakeeping performance. The scope of this methodology encompasses the assessment of ship mission scenarios and the relative importance of associated mission requirements as well as the probabilistic description of the uncertainties imposed by the variable ocean environment. The methodology is presented in a general sense so that the seakeeping performance of a ship's configuration can be evaluated as a function of mission scenario, mission area, sea state, ship heading, and speed. In order to utilize the full potential of the methodology, more refined scenario descriptions and more accurate environment specifications must be obtained. A simplified example is presented in which a comparison of the operational effectiveness of two small hull forms is made, using information now available to the designer. It is anticipated that the methodology presented can be used not only as a powerful tool in the decision-making process of practical ship design, but also as the basis for parametric studies of mission strategies.

Provision of safe drinking water, devoid of aetiologies, is an all-time challenge due to the usage of unsafe chemicals in most of the water treatment processes. The main objective of the present paper is to evaluate the use of Moringa oleifera (MO) as a natural coagulant in coagulation/flocculation (C/F) followed by the ultrafiltration (UF) of Final Effluent Treatment Plant wastewater treatment which can also be employed as an alternative to the present conventional methods of treatment. process efficiency was evaluated in terms of chemical oxygen demand (COD), biochemical oxygen demand (BOD), turbidity, total hardness, alkalinity, ammoniacal nitrogen, and zeta potential along with permeability and fouling behaviour of the membrane. A significant improvement in both the physical and chemical characteristics of the effluent quality is showing a clearer colour and a greater reduction in BOD (89.74%) and COD (63.80%) values, while pH was in the acceptable range for effluent disposal. The results indicate a lower membrane fouling rate (49%), an increase in permeate flow, and better quality of the permeate, proving that the C/F-UF treatment is an effective and efficient technique for wastewater treatment. Eventually, the treated wastewater obtained with this process generates better quality water and preserves the aquatic ecosystem.
