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.

Slip system analysis of magnesium alloy AZ31B in warm compression by Visco-Plastic Self-Consistent simulation

引用

Keikinzoku/Journal of Japan Institute of Light Metals 2024年第2期74卷 73-82页

作者： Matsuoka, Yusuke Bian, Mingzhe Tsukada, Yuhki Koyama, Toshiyuki Chino, Yasumasa Department of Materials Design Innovation Engineering Graduate School of Engineering Nagoya University Furo-Cho Chikusa-Ku Aichi Nagoya-shi464-8603 Japan Department of Materials Design Innovation Engineering Graduate School of Engineering Nagoya University Aichi Nagoya-shi Japan Multi-Material Research Institute National Institute of Advanced Industrial Science and Technology（AIST） Aichi Nagoya-shi Japan

The active deformation mode (slip systems and twinning) of extruded AZ31B alloy (Mg-3Al-1Zn, mass%) during compression at RT, 100°C and 150°C was investigated by visco-plastic self-consistent (VPSC) simulation. Compression tests were first performed to obtain compression curve of AZ31B. The VPSC model was fitted to the compression curves to estimate the Voce hardening parameters which are required for the VPSC simulation. In the case of compression along the extrusion direction, work-hardening occurred rapidly with the transition of dominant deformation modes at all temperatures. In the case of compression to the other directions, basalslip was dominant throughout the deformation at all compression temperatures. In addition, prismaticslip and tensile twin were active in the early stage of deformation, and pyramidalslip became active in the later stage of deformation. Pyramidalslip became more active with increasing temperature from RT to 100°C, whereas basaland prismaticslips became more active with increasing temperature from 100°C to 150°C. These different trends in the change of the active slip system with increasing temperature can be attributed to the CRSS maximum of the pyramidalslip located around 100°C. © 2024 Japan Institute of Light Metals.

Investigations of corrosion inhibition of ethanolic extract of Dillenia suffruticosa leaves as a green corrosion inhibitor of mild steel in hydrochloric acid medium

Corrosion Communications 2024年第3期15卷 52-62页

作者： Ukashat Mamudu Jose Hernandez Santos Saviour A.Umoren Mohamad Sahban Alnarabiji Ren Chong Lim Centre for Advanced Material and Energy Sciences(CAMES) Universiti Brunei Darussalam Faculty of Science Universiti Brunei Darussalam Interdisciplinary Research Centre for Advanced Materials King Fahd University of Petroleum and Minerals Department of Microbial and Molecular Systems Center for Sustainable Catalysis and Engineering(CSCE) KU Leuven

The utilization of plant extracts as environmentally friendly corrosion inhibitors has garnered considerable interest in the field of metallic corrosion protection. The primary objective of this study was to explore a new approach for utilizing Dillenia suffruticosa leaves extract(DSLE) to provide corrosion protection for mild steel(MS) in a molar hydrochloric acid solution. The phytocompounds responsible for corrosion prevention were extracted using ethanol with Soxhlet apparatus. The effectiveness of the extract as a corrosion inhibitor was evaluated through gravimetric and electrochemical methods, along with surface analysis of the corroded steel samples. This analysis involved the use of scanning electron microscopy(SEM) and Fourier-transformed infrared spectroscopy(FTIR) to examine the specimens with and without addition of the extract as inhibitor. The findings demonstrate that DSLE exhibits notable efficacy as a corrosion inhibitor for MS in an acidic environment. The inhibition efficiency(IE)demonstrates a positive correlation with the concentration of the extract, ultimately reaching a maximum value of 81.4 % at the optimum concentration of 1000 mg/L of the extract investigated. Potentiodynamic polarization data revealed that the DSLE functions as a mixed-type inhibitor.

Fused Deposition Modeling/3d printed technology, which has developed rapidly, is capable of making complex prototyping and can be used to produce passive safety devices. This paper investigates the interactions between the hybrid tube members and the energy absorption capabilities of Al and PLA tubes, multi-cell PLA structures, and Al/PLA hybrid tubes. For all the specimens, quasi-static axial crushing tests are conducted. The energy absorption capability of the Al/PLA hybrid tube increased by 59% compared to the single-cell Al tube. The EA value of the Al/PLA hybrid tube specimen was greater than the accumulated EA value of the PLA and Al tubes and the PLA multi-cell structures. The increase in EA value due to hybrid tube interaction is 16.36%. © Published under licence by IOP Publishing Ltd.

The exact consumption level of groundwater in many villages in Indonesia is still unknown by the regulator. In this study, we showed a working example of smart water meter that can be used to calculate daily water consumption of household in villages. The smart water meter was built from low cost open source electronic components such as YF-S201 water flow sensor, LCD display and ESP8266 microcontroller. It was also programmed with custom software to collect data from sensor and send the data to online database such as Google Sheet. It was also capable of controlling water pump for automation. The smart water meter has been tested and installed to monitor groundwater consumption of household at Tumbakbayuh village in Bali Province, Indonesia. The result has shown good data collection and it was able to send the data online consistently. From the example household data analysis has shown the average groundwater consumption of 493 liters per day. Our developed smart water meter is scalable and cost efficient to support government program in monitoring and controlling the consumption of groundwater. © 2024 IEEE.

Accurate tracking of cellular and subcellular structures, along with their dynamics, plays a pivotal role in understanding the underlying mechanisms of biological systems. This paper presents a novel approach, ProGroTrack, that combines the You Only Look Once (YOLO) and ByteTrack algorithms within the detection-based tracking (DBT) framework to track intracellular protein nanostructures. Focusing on iPAK4 protein fibers as a representative case study, we conducted a comprehensive evaluation of YOLOv5 and YOLOv8 models, revealing the superior performance of YOLOv5 on our dataset. Notably, YOLOv5x achieved an impressive mAP50 of 0.839 and F-score of 0.819. To further optimize detection capabilities, we incorporated semi-supervised learning for model improvement, resulting in enhanced performances in all metrics. Subsequently, we successfully applied our approach to track the growth behavior of iPAK4 protein fibers, revealing their two distinct growth phases consistent with a previously reported kinetic model. This research showcases the promising potential of our approach, extending beyond iPAK4 fibers. It also offers a significant advancement in precise tracking of dynamic processes in live cells, and fostering new avenues for biomedical research. © 2023 IEEE.
