Facilitating widespread adoption of electric vehicles will require next-generation battery systems that can operate reliably over a large temperature range, at high operating voltage, and under fast charging rates. Herein, a novel class of nonflammable fluorinated ester-based local high concentration electrolytes (LHCEs) are described. When cycled in commercially relevant graphite/LiNi_0.8Mn_0.1Co_0.1O₂ (NMC811) pouch cells, these electrolytes demonstrate improved capacity retention compared to carbonate-based electrolytes under multiple usage conditions including high voltage (4.5 V), fast charge (4C, 15 minutes), and low temperature (−20 °C) without sacrificing capacity retention at elevated temperature (40 °C). Low carbon, high fluoride cathode electrolyte interphases formed by the LHCE system yield a significant reduction in charge transfer impedance during cycling and contribute to capacity retention. These results demonstrate that using fluorinated esters in a LHCE modality enables creation of a new class of nonflammable electrolytes that can successfully operate over broad operating conditions. © 2024 RSC.

A compact dust collector loaded with four pleated filter cartridges is numerically studied by Computational Fluid Dynamics (CFD). The performance of the dust collector is evaluated during filtration and during backwashing, and the predictions are compared with the experimental results. In the filtration operation, the upper right corner entry design effectively guides the airflow to the two sides of the four cartridges through the air opposite-side-wall impacting and rebounding. A relatively poor filtration is found at the right side of the left lower cartridge. The CFD predictions agree well with the experimental data in terms of showing better backwash cleaning performances of the lower cartridges and at the cartridge front positions. During the 50 ms pulse-jet backwashing, the difference between the maximum and minimum air mass flow rates through a total of 16 × 2 inject holes is less than 4.0%. The high pressure of 0.5 MPa draws the air flowing from the normal exit, which acts as the majority of the backwashing air (ca. 73.7%). The hydrostatic pressure acting on the four cartridges is greater than 1750 Pa in 80% of the pulse-jet cleaning time. © 2022 Elsevier B.V.

Mathematical skills that are of major concern at this time are extrapolation abilities which require students to be able to solve mathematical problems with abstract and hierarchical concepts. To improve this capability, it can be done by integrating local technology-based traditions that have an educational philosophy. This study aims to review the integrated learning design of the local culture of Ma'dawa-dawa, Ma'manu-manu, Ma'pettuada based on android in improving extrapolation abilities. This research uses a descriptive qualitative research method with data in the form of analysis of some literature that supports research studies and is arranged descriptively containing a theoretical basis. The results of the study indicate that designed learning can be a means of developing extrapolation abilities through the integration of technology-based local cultures. © Published under licence by IOP Publishing Ltd.

Investigating the impact of metal ion variations in terephthalate metal–organic frameworks on the organic solvent nanofiltration performance of mixed matrix membranes

引用

Journal of Membrane science 2024年 700卷

作者： Ajebe, Eyasu Gebrie Hu, Chien Chieh Lugito, Graecia Hu, Chun-Po Hung, Wei-Song Lee, Kueir-Rarn Lai, Juin-Yih Graduate Institute of Applied Science and Technology Advanced Membrane Materials Research Center National Taiwan University of Science and Technology Taipei Taiwan Chemical Engineering Study Program Faculty of Industrial Technology Institut Teknologi Bandung West Java Indonesia Nanyang Technological University 1 Cleantech Loop Singapore R&D Center for Membrane Technology Chung Yuan University Chungli Taoyuan Taiwan Department of Chemical Engineering and Materials Science Yuan Ze University Chungli Taoyuan Taiwan

Nano-fillers integrated into mixed matrix membranes (MMMs) present promising alternatives for organic solvent nanofiltration (OSN). In this work, our objective is to enhance OSN performance by incorporating terephthalate metal-organic frameworks (M-BDC, where M = Zr or Cu) into a P84 matrix to fabricate M-BDC/P84 composite MMMs. This work focuses on the influence of metal cluster variation on particle size, pore size distribution, and specific surface area of M-BDC, while systematically investigating the impact of M-BDC addition on OSN performance and underlying separation mechanisms. The synthesized membranes underwent comprehensive characterization using SEM, XRD, ATR-FTIR, contact angle, zeta potential, and thermogravimetric analysis. Significantly, all MMMs exhibited superior permeance and methyl blue (MB) rejection compared to P84 membranes. This enhancement is attributed to the improved interfacial contact between M-BDC and P84, as well as their effective dispersion within the membrane matrix. Interestingly, comparative analysis between Cu-BDC/P84 and Zr-BDC/P84 MMMs revealed the latter's superior permeance, attributed to its larger pore size and surface area. The resulting MMMs demonstrated outstanding MB rejection (>96.7%) with ethanol permeance of 21.5 and 19.0 LMH/Bar for Zr-BDC/P84 and Cu-BDC/P84 MMMs, respectively. Furthermore, the stable performance of M-BDC-based MMMs during prolonged MB/ethanol operation underscores their potential significance in the field of OSN, providing valuable insights for future membrane design and application. © 2024 Elsevier B.V.

Education to the public on green products has been widely carried out. Consumers who buy green products can be profiled by segmenting green consumers. In green marketing, consumer education on sustainable consumption is increasingly needed in recent years due to the problem of environmental pollution which poses a serious threat to the world population. Concern for the environment is an important topic in most countries, and individuals also study environmental issues. Individuals or groups of individuals who are 'ecologically aware' are also referred to as 'green consumers.' Such consumers are considered to have more concern for the environment. This study examined the predictions on the effect of the Green Perceived Value variables consisting of functional, conditional, and social values on the purchase intention of green consumers. It also tested the comparisons with other classification models. The models used in this research were Random Forest, Decision Tree, and Neural Network.. © 2021 IEEE.

The performance of an electrochemiluminescence (ECL) immunosensor was improved with a particle gradient. SiO2-coated magnetic beads were adopted as nanocarriers for gradient manipulation and immobilized with the primary antibody. Cadmium telluride quantum dots were coated with a layer of protein G for conjugation and orientation of the secondary antibody as signal labels. ECL immunosensor gradients on the electrode were formed by magnetolithography (ML) with magnetized nickel masks of column and stripe arrays. The immunosensor generally aggregated as an island on the substrate, leading to a decrease of efficiency in the characteristic signals. Stripe arrays of magnetized nickel were designed to generate cylindrical magnetic flux on the substrate to improve the particle manipulation with the gradient. Various gradients of the sandwich-structured immunosensor substantially affected the electrochemical performance. Compared to the gradient-free immunosensor, the gradient of the immunosensor generated by ML using a 3 μm stripe array mask enhanced the ECL intensity ∼2.2 times. The results of quantification of epithelial cell adhesion molecules (EpCAM) with the gradient immunosensor showed a broad linear range (15-420 pg mL-1), a low limit of detection (5.5 pg mL-1), and high reliability for EpCAM-spiked serum samples, indicating that the immunosensor gradient substantially enhances the performance of the ECL assay. © 2022 American chemical Society.

Blaney, Lee Institute of Quality Standard and Testing Technology Beijing Academy of Agriculture and Forestry Science Beijing100097 China State Key Laboratory of Resource Insects College of Sericulture Textile and Biomass Sciences Southwest University Chongqing400715 China Environmental Engineering and Science Program Department of Chemical and Environmental Engineering University of Cincinnati CincinnatiOH45221 United States University of Maryland Baltimore County Department of Chemical Biochemical and Environmental Engineering BaltimoreMD21250 United States Yibin Academy Southwest University Yibin China

In this paper, Fe(IV) was analyzed in the zero-valent iron biochar (ZVI-BC) activated persulfate (PS) process with methyl phenyl sulfoxide (PMSO) as the probe compound. Without a reaction terminator, PMSO degradation continued during the sample holding time, resulting in significant errors in the kinetics analysis. When 1 mM NaNO2, 1 mM NH2OH, 10 mM Na2S2O3, and 10 mM dimethyl sulfoxide were used as terminators, the analytical interference to PMSO and its oxidation product, methyl phenyl sulfone (PMSO2), was reduced to a negligible level, enabling detection by high performance liquid chromatography. In addition to Fe(IV), free radical (i.e., SO4•–, •OH, O2•–) and nonradical (i.e., 1O2) reactive species were also involved in the ZVI-BC/PS system;however, Fe(IV) was the predominant reactive species. Generally, organic contaminants with electron-donating moieties rapidly reacted with Fe(IV), and the relative contribution of Fe(IV) to overall contaminant degradation decreased as the solution pH was increased. Overall, this study provided new insights into the quantitative analysis of Fe(IV) in the ZVI-BC/PS system and its application to treatment of organic contaminants in solutions with variable water quality. © 2024, The Authors.
