With the successful development of artificial intelligence (AI), Convolutional Neural Networks (CNNs) occupy a large amount of computing time and power consumption in the entire AI computing process. However, in traditional von Neumann architectures, the separation of the computing element and memory leads to the memory-wall problem of memory data transmission bandwidth from memory to processing element when executing multiply-accumulate-based CNN operations. The data transmission time and power consumption all are much higher than the CNN computing part. Therefore, this paper proposes a memory-in-computation design that can flexibly adjust energy usage, achieve high energy efficiency, and support multiple operation frequencies. By controlling the switches of each memory row, unnecessary energy consumption is avoided, leading to a reduction in total power consumption by 15% to 60%. Additionally, by adjusting the pulse width, the charging power consumption of capacitors is reduced by 65% per charge cycle.

The development of high-performance supercapacitor electrodes demands novel synthesis methods to precisely control the properties of the active material. Here, we report an advanced one-step approach that employs ammonium hydrogen fluoride (NH4HF2) and ammonium tetrafluoroborate (NH4BF4) as dual-structure directing agents (SDAs) to develop novel zeolitic imidazolate framework-67 (ZIF-67) derivatives (ZIF-HB), with cobalt and nickel hydroxides as the main components. Modulation of the NH4HF2/NH4BF4 molar ratio results in significant changes to the morphology, surface and electronic configurations, and electrochemical behavior. The optimized ZIF-HB (ZIF-HB12) electrode delivers impressive electrochemical performance, achieving a high specific capacitance (CF) of 1933.3 F/g at 20 mV/s. It is revealed from advanced structural analyses, including operando X-ray absorption spectroscopy that the redox reactivity and charge transfer dynamics are considerably boosted as a result of synergistic interactions between Co and Ni sites. An asymmetric supercapacitor (SC) assembled using ZIF-HB12 shows maximum energy density of 19 Wh/kg at 1143 W/kg, with a CF retention of 81.3% and a Coulombic efficiency of 97.2% after 10,000 cycles. This study highlights the effectiveness of dual-function SDAs in designing structurally robust, electrochemically active, and electronically optimized electrode materials for cutting-edge energy storage solutions. © 2025 Elsevier Ltd

作者： A. S. Budiman R. Sahay F. E. Gunawan C. Harito H. Gunawan I. Radchenko E. Navarro S. Escoubas T. Cornelius O. Thomas N. Raghavan Industrial Engineering Department BINUS Graduate Program – Master of Industrial Engineering Bina Nusantara University Jakarta Indonesia Xtreme Materials Lab Engineering Product Development Singapore University of Technology and Design (SUTD) Singapore Industrial Engineering Department Faculty of Engineering Bina Nusantara University Jakarta Indonesia 11480 Center for Advancing Materials Performance from the Nanoscale (CAMP-nano) State Key Laboratory for Mechanical Behavior of Materials Xi'an Jiaotong University (XJTU) Xi'an China Aix-Marseille Université CNRS IM2NP UMR 7334 Marseille France

nanoindentation is widely used to investigate mechanical properties of materials at small scales. In this work, owing to the presence of contrasting interfaces along rolling (RD) and transverse direction (TD), a 16 nm accumulative roll bonding (ARB) Cu/Nb nanolaminate as a test material due to its crystallographic anisotropy was used. nanoindentation was performed and then Scanning Probe Microscopy (SPM) data was conducted to measure the pile-up height along RD and TD in the nanoscale Cu/Nb multilayered materials. It was found that the 16 nm Cu/Nb ARB nanolayered material along RD showed higher surface pile-up than TD attributed the observation to the variation in the Cu/Nb interface plasticity along RD and TD. Further, a comparation and validation of experimental indentation data by performing 2D axisymmetric Finite Element Analysis (FEA) indicated that the simulation compares well with the experimentally generated load-displacement curves, while qualitative agreement was obtained with the pileup data. It is believed that the characterization of surface pile-up is very important for enabling the nanoscale Cu/Nb ARB nanolaminates as the novel stretchable/flexible metallic conductor materials (with emerging applications such as e-skins, human-computer interaction, and soft robotics) that may prove crucial for the global green and sustainability efforts (soft robots for collecting plastic trashes in ocean).

Photonic technologies continue to drive the quest for new optical materials with unprecedented responses. A major frontier in this field is the exploration of nonlocal (spatially dispersive) materials, going beyond the local, wavevector-independent assumption traditionally made in optical material modeling. On one end, the growing interest in plasmonic, polaritonic and quantum materials has revealed naturally occurring nonlocalities, emphasizing the need for more accurate models to predict and design their optical responses. This has major implications also for topological, nonreciprocal, and time-varying systems based on these material platforms. Beyond natural materials, artificially structured materials—metamaterials and metasurfaces–can provide even stronger and engineered nonlocal effects, emerging from long-range interactions or multipolar effects. This is a rapidly expanding area in the field of photonic metamaterials, with open frontiers yet to be explored. In the case of metasurfaces, in particular, nonlocality engineering has become a powerful tool for designing strongly wavevector-dependent responses, enabling enhanced wavefront control, spatial compression, multifunctional devices, and wave-based computing. Furthermore, nonlocality and related concepts play a critical role in defining the ultimate limits of what is possible in optics, photonics, and wave physics. This Roadmap aims to survey the most exciting developments in nonlocal photonic materials, highlight new opportunities and open challenges, and chart new pathways that will drive this emerging field forward–toward new scientific discoveries and technological advancements.

To the best of the knowledge of the authors, the formulation is carried out for the first time on the finite-element beam-propagation method for the analysis of the magnetooptic waveguide in which the structure varies along the propagation direction. The present method is applicable not only to the case in which refractive index difference is small but also to the case for the TE mode and the TM mode propagating in a waveguide with a large refractive index difference. To suppress the spurious reflection from the computational window edges, the transparent boundary condition is applied.

A turning point occurred in naval engineering in 1972 when the U.S. N avy chose to use marine gas turbines for the propulsion of its new SPRUANCE and PERRY Class ships. This paper reviews the more than twenty years of experience with turbine technology and its design integration into combat ships needed to make that decision. It is concluded that the availability of a good second generation aircraft derivative engine with proven reliability and a strong commercial base, i.e., the LM-2500, was as important to the decision as was the predicted improved ship effectiveness and cost benefits. This paper discusses improvements that can be made to the twin engine, single gear, single propeller shaft system. Focusing only on this mechanical transmission concept, it addresses the impact of possible improvements to the engine, gear, and shafting. In particular, the paper discusses current LM-2500 related R&D efforts to: (a) obtain improved part-power fuel rates, (b) integrate with a reversing reduction gear, and (c) add on a waste heat recovery steam cycle. Looking ahead to the year 2000, this paper suggests that a successor to the ubiquitous LM-2500 will appear in the 15 MW power range to provide the next step in the evolution of the twin engine package. This new naval engine will most likely be based on an aircraft core that exists at present, such that it will have demonstrated its reliability and commercial potential through many hours of testing prior to its mid-1990 marine conversion. This new engine is expected to offer improved air flow, an excellent fuel rate (approaching a flat 0.30 LB/HP-HR), and effective maintenance monitoring, all at some expense in size, weight, and cost. The year 2000 engine will burn a liquid hydrocarbon fuel similar to JP-5 because of its aircraft origins. Combined with advances in gear and shafting technology, the full twin engine propulsion system of the year 2000 should be markedly lighter, smaller, and more efficient than today's units.
