Reducing the rich phase ratio is a key issue for developing the biphasic absorbents. In this study, it is found that the hydrophobic solvents (sulfolane and N, N-dimethylformamide) are beneficial for reducing rich phase volume, while hydrophilic solvents (n-propanol, Polyethylene glycol) inhibit the phase splitting. Sulfolane is the optimal solvent, wherein, the rich phase ratio is greatly reduced from 79 % to 37 %. The CO2 absorption capacity in the rich phase increases from 2.50 M to 4.25 M. The kinetic studies show that the total mass transfer coefficient is increased by 1.96 times with sulfolane addition. The regeneration energy consumption of the developed absorbent is only 1.85 GJ/t-CO2, which is 53.6 % less than MEA. The results can provide a theoretical reference for developing high-performing biphasic absorbents. © 2025 Elsevier B.V.

Based on the current developed technology of molecular biology to identify the microbial populations, there are varieties of DNA extraction methods that are suitable to a certain type of sample. Among these available methods, it is necessary to select the one that provides high yield and high purity of DNA for further processing, including DNA sequencing, whole genomic analysis, or deep sequencing. This study aimed to compare the efficiencies of three different commercial DNA extraction kits with two technologies, membrane adsorption and magnetic bead adsorption, that were applied to obtain genomic DNA of rice's root-associated bacterial consortium. The yields and purities of extracted DNA were analyzed and compared by using the spectrophotometry method. The results showed that the highest DNA yield up to 223.8 ng/ul was obtained from the kit with magnetic bead adsorption. However the DNA purity (in terms of A260/A280) was low, in the range of 1.14-1.36. Then, Polymerase Chain Reactions (PCRs) were conducted to amplify a fragment of the 16sRNA gene that was subsequently sequenced. It was observed that extracted DNA samples obtained from membrane adsorption were suitable for PCR reactions, with a success rate of 83.33%, compared to magnetic bead adsorption. © 2022 ACM.

Terminal units' modification is an effective strategy for designing efficient un-fused nonfullerene acceptors (UF-NFAs) with enhanced power conversion efficiency (PCE). Nowadays, researchers are focused on designing new UF-NFAs that enhance the PCE of organic solar cells. In this line, efforts are being made to design new UF-NFAs for possible application on organic solar cells (OSCs). By doing terminal unit modification of the Cl-4F molecule, we have designed a new series of UF-NFA (ETPJ-1-ETPJ-4). Density functional theory (DFT) and time-dependent density functional theory (TD-DFT) at the B3LYP/6-311G(d,p) level have been employed for the computation of various geometric and photovoltaic aspects. Energies of highest occupied molecular orbitals (HOMO) and lowest unoccupied molecular orbitals (LUMO) with their band gap suggested that ETPJ-1-ETPJ-4 are effective contributors to the design of the efficient active layer of OSCs. Red-shift (near IR) in the absorption spectrum with easy excitation of exciton has been noted in ETPJ-1-ETPJ-4. Enhanced open circuit voltage with high fill factor percentage (FF%) was also noted for designed systems. Further, the PCE values of the ETPJ-1-ETPJ-4 are better than the reference molecule. So, we recommended a novel kind of unfused nonfullerene acceptors (NFAs) with unique S-O noncovalent interaction for possible application in OSCs. © 2023 World Scientific Publishing Company

This study aims to formulate raloxifene loaded lipid-polymeric hybrid nanoparticles (LPHNPs) and the comparison of their properties. Three LPHNPs, each with phosphatidylcholine-lipid (PCL) as bilayer-formingmembrane with three different polymers like sodium alginate, chitosan and poly(lactic-co-glycolic-acid) were prepared by nanoprecipitation, solvent injection and emulsion solvent evaporation, respectively. Results showed that the prepared formulations were spherical-shaped with a heterogeneity. Surface morphology was viewed using a scanning electron microscopy (SEM). A high entrapment efficiency (>70%) with a sustained and pH dependent drug release profile for 24 h was observed and evaluated using mathematical kinetic modelling. Fourier transform infrared spectroscopy was used to confirm successful entrapment of raloxifene after evaluating the interaction and compatibility of the excipients used. Whereas, differential scanning calorimetry and X-ray diffraction revealed the transformation of raloxifene into an amorphous form. In conclusion, these hybrid nanoparticles provide a promising approach for oral delivery of raloxifene. © 2020 Inderscience Enterprises Ltd.

Global attention on the exploration of hyperspectral imaging (HSI) system for non-destructive evaluation of detailed analyses of food and agricultural products has increased significantly. This is due to its feasibility of obtaining spectral signatures (SS) of various substances. HSI is a special type of camera capable of simultaneously capturing high precision chemometrics features for the recognition of objects pixel by pixel. Unlike the digital camera equipped with the ability to obtain the morphometric properties of an object in term of RGB (red, green, and blue) colours. High-cost implication of HSI configurations mostly hindered researchers, institutes and professionals' accessibility to this promising optical equipment. Hence this paper provides different techniques commonly employed for developing low-cost commercial off-the-shelf (COTs) and do-it-yourself (DIY) embedded artificial intelligence HSI system for future exploration potentials of handling numerous food and agricultural materials. Relevant multivariate algorithms for ease of HSI utilisation are extensively highlighted to ensure seamless future adoption. This survey, to the best of our knowledge, addressed requirements necessary for ease of HSI replication in any part of the world. It suggest possible modifications necessary for HSI development and articulates numerous techniques adopted in exploring hyperspectral imagery as an artificial intelligence technology for handling various food and agricultural materials as an embedded system. © 2024 Elsevier B.V.

The increase in biorefinery processes underscores the need for effective biofuel generation;nevertheless, inhibitors such as hydroquinone (HQ), 5-hydroxymethylfurfural (HMF), furfural (FF), and vanillin (VAN) resulting from biomass degradation impede microbial growth and process efficiency. Herein, a deep eutectic solvent (DES)-like substance was in-situ generated on the surface of NH2-UiO-66 via a post-synthetic coating process using an amine-functionalized UiO-66 MOF and choline chloride (ChCl). ChCl, selected for its low cost and non-toxic properties as a hydrogen bond acceptor, enabled the formation of the thin layer of pseudo-DES on NH2-UiO-66 under solvent-free, thermal conditions, resulting in the composite material NH2-UiO-66@ pseudo-DES. The Zr6O4(OH)4 nodes and NH2 groups in NH2-UiO-66 are capable of forming robust hydrogen bonds with ChCl, enhancing the stability and functionality of the pseudo-DES coating. Various parameters influencing the removal efficiency, including pH, adsorbent amount, initial inhibitor concentration, and vortex time, were systematically investigated and optimized. Under the optimal conditions, the removal efficiency of HQ, HMF, FF, and VAN was 62.08%, 56.09%, 45.29%, and 83.46% respectively, for a synthetic sample. These values for real samples after hydrolysis and prior to fermentation were exceeded 51.73%, 53.21%, 42.69%, and 37.59%, for HQ, HMF, FF, and VAN, respectively. Inhibitor removal is driven by hydrogen bonding, electrostatic interactions, van der Waals forces, and π-π stacking with the inhibitors. This method demonstrates effective reusability for inhibitor removal up to four cycles. This groundbreaking research is the first of its kind to employ a MOF in conjunction with a pseudo-DES for this purpose;the results are simple, very effective, environmentally friendly, quick to react, and highly selective, making it ideal for biomass hydrolysis purification. © 2025 Elsevier B.V.

Catalytic pyrolysis of plastic polymers is becoming an important method for the conversion of plastic materials into valuable chemicals and fuel production. The effect of calcination temperature on cerium loaded on oil palm ash (Ce/OPA) catalyst and products in catalytic pyrolysis of HDPE plastic were studied. The catalysts were synthesized via wet impregnation method and calcined at 500 °C, 750 °C and 1000 °C. The surface morphology and surface structure of the catalysts were also analyzed. The catalytic pyrolysis was done in a batch reactor at 450 °C with 15 ***−1 of N2 and 10:1 of plastic-to-catalyst weight ratio for an hour. The liquid products of the pyrolysis were analyzed via mass spectrometry GC-TCD, GC–MS, FTIR, bomb calorimeter and viscometer. It is found the Ce/OPA catalyst that calcined at 500 °C for four hours showed better catalytic pyrolysis activity and has largest specific surface area (10.77 m2.g−1) and and pore volume (0.032 cm3.g−1) than the catalyst that calcined at 750 °C (4.52 m2.g−1 and 0.029 cm3.g−1) and 1000 °C (3.70 m2.g−1 and 0.006 cm3.g−1). The Ce/OPA catalyst that calcined at 500 °C catalytic cracked the HDPE waste with less solid yield (25.2 wt%) and more gas yield (18.40 wt%). Meanwhile, the Ce/OPA that calcined at 750 °C and 1000 °C produced the most gases product (14.4 wt%), but the gas products that was rich in CH4 and H2 achieved when Ce/OPA that calcined at 1000 °C was used. This is because a cation-disordered phase formed in the Ce/OPA catalyst during high-temperature calcination, thereby decreasing the oxygen storage/release capacity and lowering the catalyst's pore volume and surface area. The liquid products with calorific value ranging from 50.34 ***−1–50.39 ***−1 and viscosity value between 1.06cP-1.29cP were also obtained. However, the calcination temperature did not affect the liquid product properties. In conclusion, the calcination temperature significantly affected the catalytic activity of Ce/OPA and improved p

Microbial electrolysis cells (MECs) are a new bio-electrochemical method for converting organic matter to hydrogen gas (H-2). Palm oil mill effluent (POME) is hazardous wastewater that is mostly formed during the crude oil extraction process in the palm oil industry. In the present study, POME was used in the MEC system for hydrogen generation as a feasible treatment technology. To enhance biohydrogen generation from POME in the MEC, an empirical model was generated using response surface methodology (RSM). A central composite design (CCD) was utilized to perform twenty experimental runs of MEC given three important variables, namely incubation temperature, initial pH, and influent dilution rate. Experimental results from CCD showed that an average value of 1.16 m(3) H-2/m(3) d for maximum hydrogen production rate (HPR) was produced. A second-order polynomial model was adjusted to the experimental results from CCD. The regression model showed that the quadratic term of all variables tested had a highly significant effect (P < 0.01) on maximum HPR as a defined response. The analysis of the empirical model revealed that the optimal conditions for maximum HPR were incubation temperature, initial pH, and influent dilution rate of 30.23 ?, 6.63, and 50.71%, respectively. Generated regression model predicted a maximum HPR of 1.1659 m(3) H-2/m(3) d could be generated under optimum conditions. Confirmation experimentation was conducted in the optimal conditions determined. Experimental results of the validation test showed that a maximum HPR of 1.1747 m(3) H-2/m(3) d was produced.
