We report the advantages of using CMOS directly bonded to array (CBA) technology in 3D flash memory. Improvements in interface speed, operation latency, and memory cell reliability are explored based on experimental and simulated data from 218-word-line (WL) stacked structures. The improvement derived from CBA enables BiCS FLASH™ generation 8 to operate with a high interface speed of 3.2Gbps and a high program throughput of 205MB/s with 3 bits per memory cell. A chip architecture to achieve well-scaled bit density of more than 18Gb/mm2, the world's highest in the 2xx- WL (about 218-232 WL) node, is also discussed. © 2023 IEEE.

Fin Height is critical quality parameter of DRAM device and its measurement is destructive process. This measurement process has some disadvantages – Destroying wafer/chips, limitation on number of chips for measurement leads to less data samples, and its availability towards end of production cycle. Ability of system to predict fin height early/mid production cycle serves vital role to reduce redundancy and save losses in the production pipeline. With the advent of Spectroscopic methods like Ellipsometry (SE), Reflectometry, Interferometry, it is possible to capture spectral characteristics of devices in non-destructive framework. ML/DL modelling of spectrum data learns fin height characteristics and aids prediction. Simulation of DRAM for spectrum data enables more learning data, helps to enhance fin height prediction by not just data augmentation technique of simulated data to real data. We adopt and employ Domain Adaptation (DA) methods for regression problem where DA mostly dealt with classification problem. We demonstrate significant improvement in fin height prediction accuracy by using simulated data in addition to real data via various Domain Adaptation methods. © 2024 IEEE.

A multi-physical field coupling modeling incorporated the non-thermal effect: carbothermic reduction of ZnFe2O4 by using microwave heating

引用

Energy 2025年 328卷

作者： Xiong, Yuandong Qiu, Dejin Li, Ang Omran, Mamdouh Ren, Jie Lu, Chunyang Yao, Hao Li, Manqing Xie, Hao Yu, Yaowei State Key Laboratory of Advanced Special Steel Shanghai Key Laboratory of Advanced Ferrometallurgy School of Materials Science and Engineering Shanghai University 99 Shangda Rd Shanghai China Process Metallurgy Research Group Faculty of Technology University of Oulu Oulu Finland Zhenjiang Innovation and Development Research Institute Nanjing Normal University Zhenjiang China

Microwave heating has recently gained significant attention and is increasingly applied in the pyrometallurgical recovery of Zn (ZnFe2O4) from electric arc furnace dust (EAFD). Under microwave irradiation, a portion of the microwave energy is stored within molecules, enhancing the carbothermic reduction (non-thermal effect). However, quantifying the influence of the non-thermal effect in experiments remains challenging due to the invisibility of microwaves. For advancing the scalability of microwave-assisted EAFD processing, the present study focuses on ZnFe2O4 and develops a multiphysics model incorporating the non-thermal effect to elucidate the enhancement mechanism of microwaves on the reduction process. The main conclusions indicate that increasing microwave input power and graphite addition effectively enhances both the heating and reaction efficiency of the ZnFe2O4-graphite mixture. Higher power input improves efficiency while mitigating thermal runaway risks more effectively than increasing graphite addition. However, the uneven distribution of microwaves leads to localized thermal effects, impacting heating uniformity and overall reaction consistency within the mixture. Furthermore, non-isothermal kinetic analysis reveals that microwave irradiation enhances the carbothermic reduction of ZnFe2O4 through both thermal and non-thermal effects. With a stoichiometric coefficient of 1.2 for graphite addition, localized thermal and non-thermal effects reduce the apparent activation energy by 34.3 % and 25.8 %, respectively. © 2025 Elsevier Ltd

The synthesis of microwave-absorbing materials through a combined destruction process using mechanical alloying and ultrasonic vibration is significant due to its practical, waste-free scalability. Barium hexaferrite is the best candidate for synthesizing radar absorber materials through a combined destruction process. The substitution of Mg-Al on barium hexaferrite and decreasing particle size can increase the absorption of electromagnetic waves. Mixing stoichiometric precursors Sigma Aldrich 99 % BaCO3, Fe2O3, Al2O3, and MgO through wet milling for 20 h, followed by sintering at 1200 °C for 2 h to grow crystal embryos. Mechanical alloying was used to create the single-phase BaFe12-2xMgxAlxO19 (x = 0;0.3;0.5;0.7). re-milling for 20 h and ultrasonic vibration for 2 h reduced the particle size of the Mg-Al reinforced barium hexaferrite crystalline material. The increase in Mg-Al substitution in barium hexaferrite does not change the hexagonal structure but increases the density and absorption of electromagnetic waves. Mg-Al substitution at x = 0.3 resulted in uniform average particle size of 211.8 nm with a narrow particle size distribution, resulting in the lowest reflection loss of −17.62 dB at 8.2 GHz. This research increases the absorption ability of BaFe11.4Mg0.3Al0.3O19 electromagnetic waves up to 98 %. © 2022

The development of the mylonite zone along the Median Tectonic Line (MTL), southwest Japan, which originated from the Cretaceous granitic rocks, was examined to understand strain localization during cooling. The E-W trending and north-dipping mylonitic rocks, which constitute the upper plate of the north dipping MTL, were derived from two different protoliths: protomylonitic tonalite and mylonitic granite distributed at a distance of c. 0–300 m and 300–700 m from the MTL, respectively. Microstructures and crystallographic preferred orientations (CPOs) of quartz and the two-feldspar thermometry were analyzed to infer the deformation conditions and their spatiotemporal development in the MTL mylonite zone. The mylonitic granite is further divided into southern and northern mylonite zones, which exhibit A- and B-type quartz microstructures formed by subgrain rotation and grain boundary migration recrystallization, respectively. The quartz c -axis CPOs dominantly show a medium-temperature Y -maximum pattern in mylonitic granite and protomylonitic tonalite, with some occurrences of a low temperature type-I crossed-girdle quartz c -axis CPO. The deformation of quartz originally occurred at medium temperatures of 435–490°C in the northern zone, forming mylonitic granite with a B-type quartz microstructure. As temperature decreased, the strain localized into the southern zone to form an A-type quartz microstructure at 355–435°C. The protomylonitic tonalite formed under similar temperature conditions. At temperatures below 355°C, ductile deformation ceased in most parts of granite and tonalite, and only occurred in a very narrow zone up to 50 m wide, forming ultramylonite in direct proximity to the MTL at the brittle–ductile transition conditions in quartz ( c. 300°C). The strain localization occurred not in a single shear zone but in each of the different strands of shear zones comprising the different protoliths. One of the strains developed into the crustal-scale shear zo

Evaluation of Metabolites Derived from Lactic Acid Bacteria Isolated from Kimchi

引用

ACS Symposium Series 2019年 1303卷 3-10页

作者： Hwang, Hyelyeon Lee, Jong-Hee Research and Development Division Advanced Process Technology and Fermentation Research Group World Institute of Kimchi Gwangju61755 Korea Republic of

Food fermentation facilitates long-term storage and increases the amount of active metabolites produced by lactic acid bacteria (LAB), with consequent beneficial effects for human health. Therefore, the identification of metabolites from fermented foods is important in elucidating the fermentation mechanism and improving the taste, flavor, and amount of active compounds. In this study, we cultured LAB isolated from kimchi and performed liquid chromatography-tandem mass spectrometry with principal-component analysis to analyze the metabolites produced. Kimchi is a popular Korean fermented food with numerous health benefits, and its constituent bacteria have been well-characterized. We have demonstrated that the application of an untargeted metabolomics approach can identify bacteria-specific metabolites. Using this approach, we were able to identify production of the LAB metabolite HICA and showed that HICA catabolism is positively associated with acidic environments, which is the primary physiological phenotype of fermentation. Therefore, elucidation of the specific metabolites produced by these LAB strains used in kimchi fermentation can help to provide further insight into the fermentation process and improve the nutritive value of the product. © 2019 American Chemical Society.
