Structural battery electrolytes (SBEs) possess both high ionic conductivity and high mechanical strength and stiffness. These emerging materials are critical components in load-bearing structural batteries, which offer mass and volume savings beneficial to electrified transportation and aerospace applications. However, in extreme cold (< −40 °C), conventional liquid electrolytes freeze or become too viscous to conduct ions. Further, liquid electrolytes alone are unsuitable for structural batteries because liquids cannot bear structural loads. Here, we report a two-phase solid–liquid structural battery electrolyte capable of conducting ions in extreme cold. Specifically, the structural battery electrolyte consists of a bicontinuous solid, cross-linked bisphenol A-ethoxylated dimethacrylate resin and a lithium bis(trifluoromethanesulfonyl)imide (LiTFSI)/fluoroethylene carbonate (FEC)-diglyme-based liquid electrolyte. The relative liquid/solid content was varied, and ionic conductivities of 1.62 × 10–4S/cm at −10 °C and 7.44 × 10–6S/cm at −40 °C were obtained for the case of 90 wt % liquid/10 wt % solid. When the liquid content of the structural battery electrolyte was increased from 50 to 90 wt %, the modulus decreased from 0.910 GPa to 8.13 × 10–4GPa at 25 °C, and ultimate tensile strength (UTS) decreased from 14.9 to 0.0582 MPa. These findings culminated in the application of the structural electrolyte to a graphite vs lithium metal half-cell battery operated at 0.1 C-rate where it exhibited a charging capacity of 353 mAh g–1(∼95% of graphite’s theoretical capacity). Taken together, these results have immediate relevance to the electrification of automobiles, aircraft, and spacecraft.

Graphene-based nanomaterials have been a focus of significant research in the past decade due to their multifunctional attributes. Some of the areas of interest are the role these additives can play in enhancing mechanical, thermal and electrical properties of composites. Despite numerous studies reporting successful incorporation of nanomaterials into thermoset and thermoplastic composites resulting in improved behaviors, an industrially scalable method of dispersion that addresses the agglomeration and stability of these nano-additives once incorporated in a matrix has yet to be identified. This study focuses on the dispersion of easily integratable functionalized graphene-based additives for use in epoxy resin. To achieve this goal, various loadings of nano-additives from 0.1 to 5 % by weight were used to mix with EPON 862 epoxy resin. Once mixed, the quality of dispersion was examined using optical microscopy. To study the stability of mixtures, the dispersion was monitored for 6 days with imaging performed at various times (1 hour to 6 days) post-mixing. In addition to distribution quality and stability, the effects of nano-additive incorporation on the epoxy resin's viscosity were studied under various weight percent loadings. The results found by varying the loading showed that at lower loading percentages (below 1 percent by weight), the mixture is even, stable with no significant change in viscosity. As the loading of nano-additive increases passed 1 %, the viscosity increase becomes more significant. Overall, the findings of this study show that when industrially made graphene-based nano-additives are incorporated into epoxy resin at less than 1 % loading, a uniform and stable mixture can be achieved with no significant changes in viscosity.

Good-quality triglycine sulphate (TGS) single crystals were grown in this study, and the optimisation of the TGS single crystals in the plane orientation will be discussed. This study investigates the grown crystals of TGS by using dielectric studies and discusses ferroelectric studies in detail. Dielectric studies performed on the surfaces of the plane have provided the room temperature Εr value of TGS at 9.9–10 kHz and the lower value of tan δ (0.004) and have shown the lowest level of power dissipation when the crystals are used in various applications. As expected, ferroelectric studies have demonstrated the rectangular polarisation–electric field (P-E) loop and have done so with nearly equal values of Ps = Pr ~ 2.2 μc/cm2. TGS single crystals have an order–disorder structural phase transition at the Curie temperature of 49.3 °C. The hysteresis measurements for the ferroelectric TGS family of crystals show that they are suitable for many applications. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

Recently, we developed a retarding field analyzer (RFA) with high energy resolution and wide acceptance angles, which was installed at BL25SU in SPring-8, Japan. This apparatus enables us to measure photoelectron angular distributions (photoelectron holograms) with a solid angle of ±49° in a few minutes, and this approach is now being applied to measure the atomic arrangements of dopants and interfaces. However, correcting the sensitivity distribution of the measured images by the RFA is important in processing this data. The sensitivity distribution of the RFA is difficult to measure directly because it depends on the geometry of a sample, the kinetic energy of the photoelectrons, and so forth. Therefore, we developed an image processing algorithm to estimate the sensitivity distribution using spherical harmonics. This approach is more accurate than a Fourier transform and can efficiently correct the sensitivity distribution. Moreover, the algorithm can also be adopted in a wide variety of other applications in addition to RFA measurements. © 2023 The author(s)

Purpose: The authors constructed an automatic essay scoring (AES) model in a discussion forum where the result was compared with scores given by human evaluators. This research proposes essay scoring, which is conducted through two parameters, semantic and keyword similarities, using a SentenceTransformers pre-trained model that can construct the highest vector embedding. Combining these models is used to optimize the model with increasing accuracy. Design/methodology/approach: The development of the model in the study is divided into seven stages: (1) data collection, (2) pre-processing data, (3) selected pre-trained SentenceTransformers model, (4) semantic similarity (sentence pair), (5) keyword similarity, (6) calculate final score and (7) evaluating model. Findings: The multilingual paraphrase-multilingual-MiniLM-L12-v2 and distilbert-base-multilingual-cased-v1 models got the highest scores from comparisons of 11 pre-trained multilingual models of SentenceTransformers with Indonesian data (Dhini and Girsang, 2023). Both multilingual models were adopted in this study. A combination of two parameters is obtained by comparing the response of the keyword extraction responses with the rubric keywords. Based on the experimental results, proposing a combination can increase the evaluation results by 0.2. Originality/value: This study uses discussion forum data from the general biology course in online learning at the open university for the 2020.2 and 2021.2 semesters. Forum discussion ratings are still manual. In this survey, the authors created a model that automatically calculates the value of discussion forums, which are essays based on the lecturer's answers moreover rubrics. © 2023, Bachriah Fatwa Dhini, Abba Suganda Girsang, Unggul Utan Sufandi and Heny Kurniawati.

作者： Hamid, Insha Ahmadipour, Mohsen Ahmed, Muthanna J. Rizvi, Masood Ahmad Shalla, Aabid H. Khanday, Waheed Ahmad PG Department of Chemistry Sri Pratap College Jammu & Kashmir Srinagar190001 India Institute of Power Engineering Universiti Tenaga Nasional Serdang Malaysia Department of Chemical Engineering College of Engineering University of Baghdad Baghdad10071 Iraq Department of Chemistry University of Kashmir Jammu & Kashmir Hazratbal190006 India Soft Material Laboratory Department of Chemistry Islamic University of Science and Technology Jammu & Kashmir Awantipora192122 India

One of the pollutants of emerging concern, antibiotics, have been reported in soil, water, sediment, animal manure, food, and even drinking water. Their partially metabolized forms reach wastewater treatment plants (WWTPs) and natural waters wherein the development of antibiotic resistant bacteria (ARB) and dissemination of antibiotic resistance genes (ARGs) have been reported to occur. Antimicrobial resistance (AMR) is projected to cause 10 million deaths annually across the world by 2050 in case stringent measures are not taken. In this study, various methods of adsorptive removal of antibiotics with their critical analysis and emphasis on the application of biochar (BC) and modified biochar derived from waste biomass have been comprehensively reviewed. Also, the antibiotic toxicity, preparation of biomass waste-derived BC adsorbents from cost-effective precursors to ensure sustainability, the adsorption kinetics, isotherm models and thermodynamic parameters have been discussed. It was inferred that biochars are quite efficient in terms of antibiotic removal in water owing to their large surface area, excellent surface characteristics and functionality, facile synthesis and the potential to be regenerated, while being cost-effective and sustainable in nature. This review aims to guide the expansion of research in the aforementioned area of interest and to provide a progressive push towards the development of a circular economy. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2025.
