The steelmaking industry is one of the largest sources of CO2 emissions, highlighting the urgent need for effective greenhouse gas reduction strategies. This research successfully developed innovative catalysts that integrate the reverse water–gas shift (RWGS) reaction and dry reforming of methane (DRM) to enable a three-way reforming process, utilizing CO2, CH4, and H2 as reaction gases or coke oven gas (COG) as a feedstock. Notably, it demonstrates a near-complete direct CO2 reduction from COG. Catalytic performance was optimized by evaluating supports (MgAl2O4, hydrotalcites (MG30, MG70), SiO2, and ZSM-5), metals/metal oxide loadings (Ni, Cu, Ni-Cu), and hexagonal boron nitride (h-BN). Additionally, the catalysts were characterized to elucidate their morphology, structure, and thermal stability. The 8Ni-2Cu/***30 catalyst exhibited exceptional catalytic performance, achieving high CO2, and CH4 conversion rates with remarkable CO space–time yield (3328.7 mg gcat−1 h−1). Incorporating h-BN enhanced stability, mitigating coke formation and deactivation, while COG proved to be an effective feedstock. Experiments and theory were also designed to understand the reaction mechanism further. The findings confirm that H-induced CO2 decomposition is the primary pathway for CO2 dissociation, where adsorbed H* species preferentially interact with CO2* in the gas phase, facilitating efficient conversion. This work highlights three-way reforming as a promising approach for reducing carbon emissions and enhancing by-product gas utilization, marking a significant step toward sustainable steel production. © The Author(s), under exclusive licence to Springer Nature B.V. 2025.

This paper introduces a 3D soft carbon electrode array, fabricated through a one-step laser-induced process integrating a water-dissolvable polyvinyl alcohol (PVA) mask. This approach achieves precise conical microstructures and robust conductive channels using hybrid MWCNT@PDMS conductive paste. The soft carbon electrode sites with a 3D conical microstructure are designed to enhance proximity to neural tissue, thereby enhancing electrocorticogram (ECoG) signal quality and enabling effective neural stimulation. The electrode array demonstrates remarkable stretchability (25% over 1,000 cycles without failure) and stability (equivalent to 66 days in vivo). Compared to conventional materials, our electrodes exhibit superior electrochemical properties, including lower impedance (9.7 kΩ at 1 kHz) and higher signal-to-noise ratio (SNR, 61.7 dB). Thus, this one-step process is a cost-effective, scalable solution for recording and modulating central or peripheral neural tissues. © 2025 IEEE.

Optimal Design of Wet Etching Bath for 3D Flash Memories Using Multi-Objective Bayesian Optimization

IEEE Transactions on Semiconductor Manufacturing 2025年

Recently, the complexity of semiconductor manufacturing processes has increased, resulting in a growing need for high-precision optimization of device structures. For example, in batch-type wet etching devices, the flow of chemical liquids in the process bath can vary depending on the device structure, which causes variations in the etching state of the wafer. This issue is addressed using a feedback mechanism that adjusts the device structure iteratively based on the results of an etching experiment, thereby achieving more uniform etching conditions. However, this approach requires a large number of trial experiments. In the fabrication process of 3D flash memory devices, the formation of word lines in the silicon substrate requires precise control of the silicon concentration in the etching solution. However, this concentration can fluctuate due to the dissolution of the SiN film during the etching process, which can cause various problems. Thus, this study proposes an innovative multi-objective Bayesian optimization method that is informed by image and physical quantity data from fluid dynamics simulations to derive optimal wet etching bath design parameters. The proposed method was validated through simulation experiments, and the simulation results were used to identify the best possible wet etching bath designs. © 1988-2012 IEEE.

This study presents novel magnetic core designs, magnetically anisotropic plain or tiled types, for planar spiral inductors that can effectively use magnetic anisotropy in the place of nano-granular [CoFeB-SiO2/SiO2] laminated magnetic cores. Inductance and resonant frequency for the proposed inductors showed significant enhancement through both finite element method calculation and experimentation. Additionally, the inductor was implemented onto a DC-DC converter successfully to demonstrate the step-down performance and showing corresponding waveforms. The efficiency of DC-DC converter with the inductor exhibited higher values under light load conditions. This comprehensive demonstration highlights the potential of our innovative design for advancing the field of integrated magnetics and developing more efficient power electronic devices. © 2025 IEEE.

The neural basis of sharing information through goal-directed conversation: A hyperscanning functional magnetic resonance imaging study

The human brain maintains internal models of physical and social environments, representing an individual's “subjectivity”. Through conversation, two or more individuals share their models and modify them based on the exchange, a process that represents and is referred to as “intersubjectivity.” To investigate the neural substrates of this dynamic process, hyperscanning functional magnetic resonance imaging was conducted to test the hypothesis that Inter-Brain Synchronization (IBS) in the default mode network (DMN) is involved in representing intersubjectivity. Twenty-four Japanese-speaking participant pairs played maze games over a two-day period. Each participant pair received a different maze, i.e., a maze with a different pathway to its goal. Although pairs shared a maze, each participant in a pair had only partial knowledge of the maze layout and what they knew about the layout differed. Taking turns, participants moved their pieces to their goals. Since each had only partial information about the pathway, effective communication between partners was important. Behavioral data showed participants' conversation about potential maze piece moves significantly increased as the game proceeded, implying that the exchange for such information was critical. Correspondingly, the DMN increased task-related activation, including the dorsomedial prefrontal cortex (dmPFC) and the bilateral temporoparietal junction (TPJ), extending through the superior temporal sulcus to the temporal pole and the right middle frontal gyrus. Within these areas, the dmPFC and the right TPJ showed task- and partner-specific IBS throughout all games. Thus, the DMN is likely required for representing intersubjectivity, based on internal models shared through real-time conversations. © 2025 The Author(s)

In response to the limitations of existing external pipe-crawling robots, which are unable to automatically adjust clamping force during operation, a novel external pipe-crawling robot has been designed. To enable adaptive clamping based on varying pipeline conditions, an adaptive clamping force control method based on optimal speed curve tracking is proposed. First, the target clamping force is calculated according to pipeline conditions, and it is then converted into a target speed signal through optimal speed curve planning. Subsequently, the motor precisely tracks the speed signal to achieve accurate clamping force control. Experimental results from the robot prototype demonstrate that the proposed algorithm maintains a clamping force control error rate of less than 8.0% under pipelines with different diameters, inclination angles, and surface roughness, ensuring stable operation across various pipeline conditions. © 2025, The Authors.

Cloud manufacturing is a specific implementation form of the "Internet + manufacturing" strategy. Why and how to develop cloud manufacturing platform(CMP), however, remains the key concern of both platform operators and users. A microscopic model is proposed to investigate advantages and diffusion forces of CMP through exploration of its diffusion process and mechanism. Specifically, a three-stage basic evolution process of CMP is innovatively proposed. Then, based on this basic process, a more complex CMP evolution model has been established in virtue of complex network theory, with five diffusion forces identified. Thereafter, simulations on CMP diffusion have been conducted. The results indicate that, CMP possesses better resource utilization,user satisfaction, and enterprise utility. Results of simulation on impacts of different diffusion forces show that both the time required for CMP to reach an equilibrium state and the final network size are affected simultaneously by the five diffusion forces. All these analyses indicate that CMP could create an open online cooperation environment and turns out to be an effective implementation of the "Internet + manufacturing" strategy.
