Abstract

This study investigates the adsorption capabilities of various biomass-based adsorbents for the removal of heavy metal ions from industrial wastewater. This research focusses on the comparative effectiveness of chemical and steam activation methods. Steam-activated adsorbents derived from wine sector waste exhibited a maximum adsorption capacity for Pb²⁺ ions of 399 mg/g. Adsorbents derived from walnut shells and chemically activated with HNO₃ ions exhibited a maximum adsorption capacity of 204.08 mg/g for Cu²⁺ ions. Steam-activated spruce sawdust adsorbents achieved optimal adsorption of Fe²⁺ ions at a capacity of 329 mg/g. The adsorption capacity for Cd⁺ ions was determined to be 116 mg/g, achieved through microwave-assisted steam activation of palm kernel shell-based adsorbents. The research emphasizes the necessity of selecting appropriate activation techniques based on specific heavy metal ions and the desired adsorption properties. Additionally, there is a necessity for further investigation into the processes of pore structure development and their impact on adsorption effectiveness. The findings suggest that developing adsorbent from biomass waste represents a sustainable and effective method for reducing heavy metal contamination in industrial wastewater, thereby advancing environmental protection and resource efficiency.

Abstract

Edible films serve as an effective barrier to prevent mass transfer between the product and its environment. This innovation facilitates the development of environmentally sustainable food packaging alternatives that promote the efficient use of natural resources. A variety of biopolymers are utilized in the formulation of edible films, primarily polysaccharides, proteins, and composite materials. Polysaccharides can be further categorized according to their origin, including plant, animal, marine, microbial, and industrial waste sources. Proteins are generally classified into plant- and animal-based categories. Composite films, which combine multiple biopolymer types, offer enhanced structural properties. The application of biopolymer-based edible films presents a promising strategy for mitigating commercial plastic waste accumulation. Nevertheless, the incorporation of additives—such as plasticizers, antioxidants, and antimicrobial agents—is essential to enhance film properties and ensure compliance with quality standards for food packaging application

Abstract

Hydrogel polymers have emerged as transformative materials in the field of flexible electronics, offering unparalleled properties such as high water content, mechanical flexibility, and tunable conductivity. This review critically examines the thermal stability of hydrogels and their applications in electronic devices, with a focus on smartphone technology. Despite their inherent susceptibility to thermal fluctuations—ranging from freezing-induced brittleness to dehydration at elevated temperatures—recent advancements have significantly enhanced their resilience.  Strategies such as incorporating cryoprotectants (e.g., glycerol, ionic liquids), optimizing crosslinked networks, and balancing hydrophilic-hydrophobic interactions have proven effective in mitigating these challenges. These innovations enable hydrogels to maintain functionality in extreme environments, making them ideal for flexible sensors, energy storage devices, and touch screens. Notably, thermoresponsive hydrogels, which exhibit reversible phase transitions at critical solution temperatures, are paving the way for adaptive cooling systems and dynamic interfaces in next-generation electronics. The integration of hydrogels into electronic devices not only addresses thermal management issues but also unlocks new possibilities for wearable and biodegradable technologies. This review underscores the interdisciplinary potential of hydrogels, highlighting their role in advancing sustainable, high-performance electronic systems while identifying future research directions to overcome existing limitations.

Abstract

Abstract. This research utilized dolomite rock (CaMg(CO2)2) to produce CaO-MgO material using precipitation-dehydration. The precipitation-dehydration method was carried out by dissolving dolomite in 10% hydrochloric acid (HCl) solvent and precipitating in 2 N sodium hydroxide (NaOH) solution at a temperature of 80 oC. The resulting products were analyzed using Scanning Electron Microscope-Energy Dispersive X-Ray (SEM-EDX) and Brunauer-Emmett-Teller (BET). The acidity level of the solution was analyzed by using a pH meter. The analysis results using SEM-EDX show that the material has a characteristic chemical composition with a Ca/Mg ratio less than 1. The results of BET show that the average surface area, average pore volume, average pore size and average particle diameter are 71.1213 m2/g, 0.1081 cc/g, 20.5165 nm, and 36 nm, respectively. The solution's acidity (pH level) in precipitation-dehydration is 8-8.5. It is identified that precipitation-dehydration can be used for CaO-MgO recovery and further application in catalyst materials.Keywords:Dolomite rock, Calcium oxide, Magnesium oxide, Precipitation-dehydration

Abstract

Abstract. Currently, Enhanced Oil Recovery (EOR) technology is being interested in the Indonesian state as an advanced technology that can recover oil remaining in the reservoir. The discovery of new resources and EOR efforts are predicted to result in increased oil production. This paper provides a review of main types of EOR methods, which are gas injection, thermal injection, and chemical injection; mechanism of polymer flooding; and biopolymer materials for EOR, attention were given to xanthan gum, cellulose, guar gum, and lignin. Polymer flooding is a low-cost chemical injection method with a high rate of success. Polymer flooding has several advantages, including improving oil recovery by minimizing residual oil saturation, decreasing water output from oil well, and requiring less water compared with water flooding. Since the use of polymer flooding in the EOR activities, there is a lot of potential that biopolymers are materials that play a significant role in the application of EOR technology, because environmentally friendly properties and have advantages over synthetic polymers. Biopolymer can be modified to nano materials or grafted with synthetic polymer to improve its properties and stability. It have shear, salinity, and temperature resistance, long-term stability, and large availability, so it making the right choice for applications in oil recovery.Keywords:Enhanced oil recovery, EOR, biopolymer, polymer flood, modification of biopolymer

Abstract

This research established an artificial neural network (ANN) aimed at optimizing ozonation for chemical oxygen demand (COD) reduction in animal feed plant wastewater. Experimental data (200-1000 mg/L COD, 100-180 min treatment) were used to train a 10-8 neuron artificial neural network, resulting in a predicted removal rate of 97.4% at 180 minutes for 1000 mg/L COD (MSE=15.9, R²=0.34).  Experiments indicated a marginally higher efficiency of 97.83% at 160 minutes; however, the ANN's conservative recommendation of 180 minutes is more appropriate for industrial scalability. The model successfully identified non-linear degradation patterns of recalcitrant organics, illustrating the potential of artificial neural networks for optimizing wastewater treatment.  This study connects laboratory research with industrial application via machine learning, establishing a framework that balances efficiency and operational practicality. Future improvements may integrate real-time process data to increase accuracy.

Abstract

ABSTRACT. Polymers have become essential excipients in pharmaceutical formulations, significantly enhancing drug delivery systems due to their versatility, biocompatibility, and specialized properties. This review discusses the role of natural  and synthetic polymers, which are favored for their biodegradability and ability to improve drug stability and controlled release. The paper highlights innovations in polymer-based drug delivery, including the development of stimuli-responsive polymers that release drugs in response to specific environmental triggers and the integration of natural and synthetic polymers to create hybrid systems. Despite the advantages, challenges such as variability in natural polymer sources, potential toxicity of synthetic polymers, and regulatory hurdles remain. Future prospects include advancements in green and sustainable polymers, personalized medicine, and the use of nanotechnology to enhance drug delivery efficacy. This comprehensive examination underscores the importance of interdisciplinary research in overcoming existing barriers and advancing polymer-based drug delivery systems to improve patient outcomes. Keywords:Polymer, Drug delivery, Natural polymer, Synthetic polymer, Stimuli-responsive
