Thermo ‐mechanical properties and optimization of sodium alginate as a polymer backbone substrate for biosensor application
This study was aim to optimize the formulation of the sodium alginate biosensor substrate with incorporation of sodium alginate (1%-6%(w/v)) as a polymer backbone and glycerol (10 –50 wt%) as a plasticizer. The effect of their interaction on film's tensile strength (TS) and elongation at break (EB) were analyzed via response surface methodology-central composite design (RSM-CCD). The optimum parameter of the films for the maximum TS was at 1.90%(w/v) of sodium alginate and 17 wt% of glycerol and for maximum EB was at 4.89%(w/v) of sodium alginate and 49.65 wt% of glycerol.

Modeling the fate of microplastics in the Sengkarang Estuary, Pekalongan City, Central Java, Indonesia
This study aims to determine the concentration and distribution of microplastics in water and sediment at the mouth of the Sengkarang River, Pekalongan. A total of 10 water samples and five sediment samples were collected from the river body to the deep water area around the Sengkarang River. Modeling of microplastic distribution is made using hydrodynamic modeling and particle tracking models using two-dimensional mathematical model. The results showed that the abundance of microplastics ranged from 131 to 360 particle/m3 in water samples and 552.5 –972.5 particle/kg in sediment samples. The most common types of micr...

Synthesis and characterization of TiO2 foam and SiO2@TiO2 core ‐shell nanostructure for gnetin dye degradation from industrial effluent
AbstractThe current study intends to create TiO2 foam, SiO2 nanoparticles (NPs), and SiO2@TiO2 core-shell nanostructure (CSN) with improved photocatalytic durability for the quick degradation of the textile industrial water pollutant in the presence of sunlight. The sol-gel, St öber, and chemical co-precipitation methods have been used to synthesize TiO2 foam, SiO2 NPs, and SiO2@TiO2 CSN. X-ray diffraction results have revealed the anatase phase of TiO2 foam, the amorphous nature of SiO2 NPs, and the amorphous nature of SiO2@TiO2 CSN due to equal wt.% of SiO2 NPs and TiO2 foam at 300 K. Field emission scanning electron mi...

Bioremediation of phenolic compounds in coal ‐contaminated environments: Bio‐kinetic studies using a mixed bacterial culture
AbstractTwo distinct bacterial strains were combined in a mixed culture to investigate the degradation of phenol. The mixed cultures consisting of species likeRhodococcus andBacillus, were isolated from the waste effluent collected from Dankuni coal complex (DCC) in West Bengal. The experimental phenol biodegradation were performed batch wise at an optimized temperature and pH conditions of 37 °C and 7.0 for a wide range of phenol concentrations initially, with saline solutions which is not supplemented with nutrients initially. Experimental results concluded a highest possible specific growth rate at 150 mg/L for phenol...

Evaluation using the SWAT model of the effects of land use land cover changes on hydrological processes in the Gala Lake Basin, Turkey
AbstractChanges in hydrological processes in watersheds are triggered by various factors, including land use land cover changes (LULCC) emerging from human activities. Hence, it is crucial to elucidate the interaction among hydrological processes to improve sustainable water management plans. The current study explored the effects of LULCC on hydrological processes in the Gala Lake catchment over a 30-year temporal period. In this context, to evaluate LULCC, land cover maps were obtained using the supervised classification method with Landsat images (5 TM, 7 ETM+, 8 OLI) of 1993, 2008, and 2023. Hydrological processes were...

Biogas generation through anaerobic digestion of orange peel waste and crude glycerol in single ‐stage and two‐stage batch system
AbstractOrange peel waste (OPW) and crude glycerol (CG) can be used in anaerobic processes. To avoid inhibition due to D-limonene from OPW, the process can be carried out in two stages. Thus, this work aimed to evaluate the generation of methane in biogas through the anaerobic digestion of OPW and CG, individually and mixed, in a single-stage and two-stage batch system. For this purpose, the biochemical methane potential (BMP) of the wastes, separately and mixed, was determined in a single-stage system (methanogenic phase) and in a two-stage system (acidogenic and methanogenic), following the German standard VDI 4630. The ...

Fuzzy ‐AHP methodology for ranking of hospitals based on waste management practices: A study of Gwalior City
AbstractWithin the scope of this research, the fuzzy-analytical hierarchy process (F-AHP) method is applied to assess the waste management approaches adopted by various hospitals in the city of Gwalior, India. Fuzzy-AHP, as an alternative to traditional AHP, accommodates uncertainty and imprecision, offering a decision-making method that is more adaptable and realistic. The F-AHP methodology, delineated in a seven-step process, incorporates pairwise comparisons, fuzzy mathematics, and linguistic variables to compute fuzzy weights for waste management criteria, encompassing physical, biological, social, and economic aspects...
