Smart grids are faced with a range of challenges, such as the development of communication infrastructure, cybersecurity threats, data privacy, and the protection of user information, due to their complex structure. Another key challenge faced by smart grids is the stability issues arising from variable energy sources and consumption patterns. In these complex grid systems where energy demand and supply need to be balanced instantly, stability predictions play a significant role in foreseeing potential disruptions and optimizing energy flow. Therefore, within the scope of this study, a hybrid structure utilizing recurrent Neural Networks (rNN) and Long Short-Term Memory (LSTM) networks is employed for stability classification to predict grid stability. This hybrid model combines the ability of rNN to recognize relationships between consecutive data points with LSTM's capability to preserve long-term dependencies. The results obtained indicate that the model exhibited stable performance with accuracy rates of 98.06% and 98.02% at 50 and 100 epochs, respectively. The findings of this study contribute valuable insights to research on the management and stability of smart grids, enabling energy systems to be operated more reliably and efficiently. © 2024 IEEE.

Chemical engineering Journal 2025年 505卷

While the contradiction between permeability and selectivity is an inherent drawback of membrane-based molecular separations, most conventional adsorbents with high adsorption capacity suffer from the same balance between adsorption and desorption. In this study, super hydrophilic hollow mesoporous carbon nanospheres (Hs) based on chitosan chain wrapping were synthesized using hydrothermal reaction. A new generation of temperature-responsive smart adsorbents (Hs-TrP) was prepared by free radical polymerization of chitosan and the temperature-sensitive molecule N-isopropylacrylamide (TrP) in aqueous solution. The adsorbent will freely switch the on/off state of the molecular gate with the rise and fall of temperature to realize the intelligent regulation of selective adsorption and rapid desorption. More importantly, the temperature difference required to switch states is very small, which significantly reduces energy consumption. Finally, a super hydrophilic smart adsorption membrane was prepared by grafting 2-acrylamido-2-methylpropanesulfonic acid (AMPS) monomer via free radical graft copolymerization reaction to confine Hs-TrP on the surface of PVdF membrane. Modified membranes exhibit both efficient separation of oil and water and dyes as well as antimicrobial properties, with a water flux two orders of magnitude higher than that of typical pressure-driven membranes with similar removal rates. Moreover, the membrane can be effectively cleaned by the adsorption/desorption process, and the flux recovery rate can reach 96% for each cycle, and the retention recovery rate of methylene blue can still reach 98% after several cycles. The membranes we present here provide a simple and effective platform for low-energy wastewater remediation. © 2025 Elsevier B.V.

作者： Chen, Yu-Chen Li, Po-Yu Kung, Chung-Wei Chang, Jhe-Wei Kao, Cheng-Wei Kuo, Chi-Ching Liu, Wei-ren Department of Chemical Engineering Chung Yuan Christian University R&D Center for Membrane Technology Center for Circular Economy 200 Chung Pei Rood Chungli District Taoyuan City32023 Taiwan Department of Molecular Science and Engineering Institute of Organic and Polymeric Materials National Taipei University of Technology Taipei106 Taiwan Department of Chemical Engineering National Cheng Kung University Tainan City70101 Taiwan National Synchrotron Radiation Research Center Hsinchu30076 Taiwan Advanced Research Center for Green Materials Science and Technology National Taiwan University Taipei10617 Taiwan

In this study, we proposed a blue-excitable and near-infrared (NIr) emission ceramic phosphor - Gd3Ga5O12:Cr3+, Nd3+ (GGO:Cr, Nd) by a solid-state reaction for light-emitting diode applications. The as-synthesized Gd3Ga4.95Cr0.05O12 phosphor displayed a broad emission peak at 759 nm (4T2 → 4A2) with a full-width-half-maximum of 122 nm under 460 nm excitation. In order to generate NIr, we introduced Nd3+ ions as activators to substitute Gd3+ ions in GGO:Cr3+ phosphors. Via energy transfer from Cr3+ ions to Nd3+ ions in GGO, an intense NIr emission at 1064 nm resulting from 4F3/2 → 4I11/2 is demonstrated. Furthermore, we investigate the doping effects at various concentrations and reanalyzed the luminescent characteristics of (Gd1-yNdy)3(Ga1-xCrx)5O12 phosphors to determine the optimal doping concentration of Cr and Ni, which were found to be 1 mol.% and 3 mol.%, respectively. Finally, we mix the composition-optimized (Gd0.97Nd0.03)3(Ga0.99Cr0.01)5O12 NIr-emission phosphor with silica-based glass powder. After cold pressing and high-temperature sintering using molds, we obtain NIr-emitting glass-ceramic phosphors through laser cutting technology and packaged them into high-power light-emitting diodes. © 2024 Elsevier Ltd and Techna Group S.r.l.

NIPAAm has been widely used in cell culture and non-destructive desorption in recent years because it can change its surface configuration by changing temperature. In this study, NIPAAm was grafted onto the surface of the HFMs with cerium ammonium nitrate (CAN) as the initiator to prepare the thermosensitive HFMs. This material was used as a cell carrier for temperature sensitivity and biocompatibility assays to achieve non-destructive harvesting of cells from the surface of the HFMs. The morphology showed that poly (n-isopropylacrylamide) (PNIPAAm) was successfully grafted onto the HFMs. The results of water contact angle at different temperatures showed that the prepared samples have good temperature sensitivity. At 37 °C, PC12 cells adhered to and diffused well on the surface of PNIPAAm-g-HFMs. After cooling to 20 °C, the cells fell off the surface of the membrane in sheet form and retain more extracellular matrix proteins. PNIPAAm-g-HFMs in this study have good biocompatibility and can be better used as cell carriers in cell culture in vitro. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

This study introduces an innovative extreme ultraviolet (EUV) resist featuring a vertically oriented molecular wire architecture, designed to achieve exceptionally low line edge roughness (LEr). The resist is synthesized via molecular layer deposition, a gas-phase technique that allows precise monolayer-level control over thickness, ensuring excellent reproducibility, conformality, and uniformity. The hybrid multilayer resist is constructed through controlled ligand-exchange reactions between diethylzinc and 3-mercaptopropanol (3MP), which create vertically oriented molecular wires with widths below 1 nm. This innovative structure achieves an unprecedentedly low LEr of 1.37 nm at a dose of 60 mJ/cm2. EUV exposure induces unique cross-linking coordination bonds between the zinc atoms and the oxygen and sulfur atoms in 3MP without degassing, thereby enhancing EUV sensitivity. The combination of vertically oriented high-aspect-ratio molecular wires and effective lateral cross-linking significantly improves EUV sensitivity and robustness during etching. This pioneering hybrid multilayer EUV resist may satisfy the stringent requirements of advanced semiconductor manufacturing. © 2025 Elsevier Ltd

Poly (m-phenyleneisophthalamide) (PMIA) is a promising candidate for membrane material resulting from its excellent thermal and chemical stability. Being the linear molecular structure, almost all studies have been carried out on PMIA as a substrate material for thin-film composite (TFC) membranes rather than an active layer. Here, amino-epoxide crosslinkers were introduced into the PMIA dope solution to modify the molecular structure for the first time. Employing the casting coupled solvent evaporation deposited the crosslinked PMIA (CPMIA) thin-film. The effect of crosslinker type and concentration on the morphology and the ion permeance have been investigated systematically. That is, achieving the separate optimization of the active layer. Based on the CPMIA thin-film with the best ion permeation, novel TFC membranes (TFC-CPE) with CPMIA active layer were generated successfully via the thin-film liftoff (T-FLO) technique for the first time. result demonstrates that TFC-CPE had desirable dye desalination performance. For feeding solution containing 100 ppm Cr and 1 g L-1 NaCl, the permeance was 25.17 L m-2 h-1 bar-1. Cr rejection was 99.88% and NaCl rejection was 6.30%. The selective coefficient α was up to 793.9. It also demonstrated that the TFC-CPE had excellent thermal resistance, anti-fouling capability and long-term stability. In conclusion, the novel TFC membrane has a promising future for in-situ dye wastewater treatment. This work throws light on the PMIA modification and the preparation of the TFC membrane with a novel active layer. © 2023, The Authors. All rights reserved.
