A novel double-coating technique was employed to encapsulate levofloxacin (LVF), a potent antibacterial drug, using the particles from gas-saturated solutions (PGSS) process to achieve extended release. The primary coating utilized glyceryl tristearate (GT), a lipid with a high melting point (72 °C), followed by a secondary coating with trimyristin (TM), a lipid with a lower melting point (52 °C). For comparison, a single-coating approach was also explored, using the biocompatible polymer poly-(ε-caprolactone) (PCL). The resulting particles were characterized for their shape, size, and LVF encapsulation efficiency, with confirmation of LVF entrapment provided by Fourier transform infrared (FTIR) spectroscopy, and X‐ray powder diffraction (XRD) analysis. The particles, with an average diameter of 95.3 ± 16.5 μm, exhibited an encapsulation efficiency of up to 92.1 ± 2.5%. Furthermore, in vitro release studies revealed that the double-coated microcapsules effectively suppressed the initial burst release and provided controlled, extended release of LVF (t30D = 36.3%), demonstrating the efficiency of this encapsulation method for prolonged drug delivery.

Optoelectronic, mechanical, and thermoelectric characteristics of the material halide perovskite RbBeX3 (X = Cl, Br, I) are theoretically investigated in the current work. The structural and elastic properties of mentioned materials are examined using the generalized gradient approximation (PBEsol), whereas electronic and thermoelectric properties are better understood using the modified Becke-Johnson (mBJ) functional technique. Born Criteria along with energy of formation have been examined for stability of all of these halide perovskite variations. The elastic constants of the cubic symmetry are investigated to ascertain anisotropy, Debye temperatures, and the distinction between brittle and ductile nature. Based on the mBJ potential, the bandgaps for RbBeCl3, RbBeBr3, and RbBeI3 are 3.8 eV, 2.1 eV, and 0.45 eV, respectively. To confirm the optical properties inside the visible region, all of these halide perovskites are further analyzed for their properties such as absorption, refractive index, and dielectric constants in the energy range 0–14eV. Furthermore, because of their lower values thermal conductivity, larger values of Seebeck coefficient, and Figure of merit (ZT), these halide perovskites are also suitable candidates for thermoelectric applications. © 2025 Elsevier Ltd and Techna Group S.r.l.

Four coal samples from the Upper Kutai, South Sumatra, and Meulaboh basins were analyzed using chemical, petrographic, and thermogravimetric–mass spectrometry (TG-MS) methods to characterize their composition and thermal behavior during pyrolysis and gasification. chemical and petrographic analyses revealed that the samples vary in rank, ranging from sub-bituminous C to high-volatile A bituminous coal (vitrinite reflectance, Rr, between 0.34% and 0.86%). Vitrinite is the predominant maceral, comprising 71.90% to 86.30% by volume. Thermal decomposition during both pyrolysis and gasification was found to be more strongly influenced by coal rank than by maceral composition. During pyrolysis, higher-rank coals exhibited lower thermal decomposition rates. CO₂ was the first gas released during thermal cracking, followed sequentially by CH4, H₂O, and H₂. The latter becoming the dominant gas in the later stages of pyrolysis. In CO₂-driven gasification, the sub-bituminous C coal exhibited a maximum char reactivity of 0.61 mg/min, compared to just 0.01 mg/min for the high-volatile A bituminous coal. Carbon monoxide (CO) was the primary syngas produced during the gasification process. © 2025 Taylor & Francis Group, LLC.

Body shaming remains a prevalent concern in the fashion business, as conventional beauty standards sometimes exclude persons with varied body shapes. This study investigates the effect of pattern grading and motif grading approaches on reducing body shaming, particularly in the context of batik shirt production. The research highlights how various grading systems improve garment fit and cater to a broader range of body shapes, thereby challenging body shaming and promoting body inclusivity. The research examines the impact of grading methods on tailors' engagement, skill level, and self-assurance, showing that these methods enhance garment quality and empower industry professionals. This study employed a mixed-method approach, combining the creation of graded batik shirt prototypes with quantitative analysis using Partial Least Squares Structural Equation Modeling (PLS-SEM). The research indicates that motif grading maintains the traditional validity of batik designs while facilitating size modifications. Tailors expressed strong interest in adopting grading techniques, and the study proposes inclusive design solutions that effectively address body shaming in a traditional manner. The results suggest that integrating grading methodologies into fashion processes can foster a more inclusive and diverse business. Suggestions are offered for fashion designers, educational institutions, and companies to promote the implementation of grading techniques that accommodate body variation. This research identifies future research opportunities, such as incorporating technology in grading and formulating design methods to mitigate body shaming in the fashion industry. © 2025 The Authors

Despite being an efficient bioremediation agent, aquatic biofilm's usefulness as a biomonitor has not been explored extensively. This study disclosed the potential of epilithic biofilm as biomonitor by comparing its metagenomics with water quality parameters and microplastic count in Brantas River. Metagenomics showed the epilithic biofilm was dominated by Exiguobacterium, which recognizes and degrades microplastics, along with Rhodobacterium and Rhizobiales. For the first time, biofilm microbes and their respective roles were discovered to correspond to the total microplastic counts in comparison with BOD as the only transgressing physicochemical parameter. Thus, epilithic biofilm is a potential biomonitor for riverine microplastic contaminations. © 2024 The Author(s)

This study investigates the thermal performance and energy efficiency of a biomass-fueled vertical dryer utilizing candlenut shell biomass for corn drying. The objective is to evaluate drying behavior under continuous and discontinuous operation modes at different temperature settings. A custom-built dryer was developed and tested at 45 °C, 50 °C, and 55 °C, and energy input, drying time, and efficiency were recorded. Statistical analyses, including paired t-tests, were conducted to examine the significance of operational differences. Results show that continuous drying at 50 °C and 55 °C significantly improves drying efficiency, reaching above 66 %, and reduces drying time compared to discontinuous modes. Candlenut shells performed well as a renewable fuel, offering stable combustion and minimal ash production, outperforming traditional fuels such as rice husks and corn cobs in similar drying conditions. Energy analyses indicated balanced energy use, while future work should address post-drying quality characteristics and automation. These findings suggest that candlenut shells are a viable, sustainable alternative for efficient post-harvest thermal processing, particularly in rural agro-industrial settings. © 2025 The Authors

Enhanced peroxi-coagulation process for the treatment of anaerobically-treated palm oil mill effluent (POME)

引用

Journal of Industrial and engineering Chemistry 2025年

作者： Ismail, Saiyidah Anisah Ang, Wei Lun Mahmoudi, Ebrahim Mohammad, Abdul Wahab Wong, Wai Yin Department of Chemical and Process Engineering Faculty of Engineering and Built Environment Universiti Kebangsaan Malaysia Selangor Bangi43600 Malaysia Chemical and Water Desalination Engineering Program College of Engineering University of Sharjah Sharjah27272 United Arab Emirates Fuel Cell Institute Universiti Kebangsaan Malaysia Selangor Bangi43600 Malaysia

This study investigated the effectiveness of the peroxi-coagulation (PC) process in removing dissolved organic impurities from palm oil mill effluent (POME). Key experimental parameters assessed in this study included wastewater pH, electrolysis duration, and the dosage of H2O2. After a five-hour treatment period, maximum breakdown of organic contaminants and removal of suspended particles were achieved, with around 86 % of soluble COD (SCOD), 91 % of total COD (TCOD), 99 % of true colour, and 84 % of turbidity were removed under optimal operating conditions (pH 3 and external dosing of 31.09 mM H2O2). These outcomes can be attributed to two removal mechanisms: the predominant Fenton oxidation reaction at low pH which promoted effective •OH generation from the dosed H2O2, and the simultaneous coagulation activity by the electrochemically produced Fe(OH)3 coagulant. This PC process was governed by the pseudo-first-order kinetic model, which achieved a maximum kinetic rate of 0.5321 min−1 under ideal operating conditions. The estimated energy consumption for POME degradation ranged from 0.461 to 1.874 kWh per kg of COD reduced, indicating low electrical energy intake. These findings demonstrate the potential of the PC process as a pre- or post- treatment step that can enhance the removal of COD and pigmentation in integrated POME treatment systems. © 2025 The Korean Society of Industrial and engineering Chemistry

Syngas fermentation effectively converts CO, H₂, and CO₂ into valuable biofuels and chemicals. This study investigated the effects of fluctuating syngas composition and kLa as the critical operational parameters on microbial fermentation performance, with a focus on ethanol, acetic acid, and biomass production. Modeling results demonstrated that increasing CO concentration significantly enhanced metabolite production, whereas increases in H₂ and CO₂ concentrations yielded limited improvements. The findings revealed that a higher H₂/CO ratio tent to reduce metabolite production, while a higher CO/CO₂ ratio significantly improved fermentation outcomes. Additionally, higher kLa values were observed to promote metabolite production, though diminishing returns were evident at very high kLa levels. Further study on the impact of syngas composition disturbances (±5% to ±20%) and fluctuation durations (0.5, 1, 2, and 4 days) indicated that larger disturbances and longer fluctuation durations led to greater deviations in metabolite concentrations, with ethanol being the most sensitive, followed by acetic acid and biomass. Despite these fluctuations, the microbial system displayed resilience, stabilizing once gas composition returned to normal levels. These insights underscored the adaptability and robustness of syngas fermentation systems, making them viable for industrial applications where gas composition variability is inevitable. The ability to tolerate moderate fluctuations offers opportunities to reduce gas pretreatment costs and process syngas from diverse sources, benefiting industries such as steel manufacturing, oil refining, and biomass gasification.
