Activated carbon from Acacia mangium wood was prepared by chemical activation using H₃PO₄ under optimum conditions (OAMW-AC). In this study, a rotatable central composite design of response surface methodology was used to optimize the adsorption capacity of OAMW-AC against caffeine molecules. The maximum removal capacity of the OAMW-AC was found to be 29.2 mg/g under optimized conditions. The experimental results established optimized conditions for maximum caffeine removal were;61 min of contact time, 3.0 g/L of adsorbent dosage, 100 mg/L of initial caffeine concentration, and 7.60 solution pH. The surface morphology, surface elemental composition, and surface functional group changes on the OAMW-AC were monitored by field emission scanning electron microscopy images, energy dispersive X-ray spectroscopy, and Fourier transform infrared spectroscopy, respectively. The characterization data showed OAMW-AC had a Brunauer-Emmet-Teller (BET) surface area of 1767 m²/g with dominated mesopore area (94.8 %). The pH at the point of zero charges (pHzpc) was 2.25, and the negative value of proton binding capacity (Q = − 0.23 mmol/g) showing proton dissociation from the carbon surface at pH above pHzpc. A desorption study of the caffeine through 95 % ethanol solution was also carried out. It was observed that 37.2 % of the adsorbed caffeine could be reclaimed from activated carbon. © 2021 Elsevier B.V.

Hydrological modeling required essential input data such as river bathymetry, discharge, topographic and floodplain elevation values, manning’s n values, and precipitation. In this study, river bathymetry and spatial distribution of precipitation were focused because of challenges in their estimation and associated uncertainties. These input data are also important in accurate flood risk and vulnerability assessment. Previous studies developed several models for their estimation using remote sensing and GIS. However, further improvement is required for their accurate estimation. This study will be helpful in accurate spatio-temporal estimation of these two input data. Furthermore, it was suggested the use of machine learning approaches to handle big data obtained from satellite images for further improvement in the spatio- temporal estimation.

Frying potato chips developed a tasty product with crispy, tempting aromas and excellent appeal of potato chips, but high oil content in deep-fry potato chips will increase adverse health effect to the consumer. This research was conducted to evaluate the effect of the composite coating (pectin-maltodextrin) of potato chips characteristics at different ratios (uncoated, 100:0, 90:10, 80:20, 70:30 60:40 and 50:50 or named as sample 1, 2, 3, 4, 5, 6 and 7, respectively). The potato chips were coated using dipping method and characterized through evaluations of fat content, moisture content, texture and sensory. Sample 6 (60:40) has the significant highest fat reduction (9.69%) among the samples. The moisture content for all samples were not significantly different (P > 0.05). Coated potato chip of sample 4 (80:20) has the highest breaking force (2.78 ± 0.07 N) compared to uncoated potato chip (2.24 ± 0.13 N). The sensory evaluation showed that coated potato chips were preferable compared to uncoated potato chips. In conclusion, composite (pectin-maltodextrin) coated potato chips obtained enhanced characteristics including significant fat reduction, improving texture and sensory acceptability.

Metal inert gas (MIG) welding is an arc welding process that is used in many industrial fields. MIG welding is remarkable because of high penetration and quickness in producing welds process. However, MIG welding has some disadvantages including less stable arc, high spatter, and production of smoke and fumes in the process of welding. In this study, the four different travel angles (90, 75, 60 and 45) are used to investigate the effect of travel angle on the welding quality, microstructure formation at heat affected zone and the mechanical property. Pure argon is used as the shielding gas with constant current, voltage, and welding speed. The result shows that the lower travel angle produces higher penetration depth and reinforcement. However, lower travel produces more porosity compared to higher travel angle. The use of lower transfer/travel angle during MIG welding contributes to the deep penetration, high reinforcement of the weld bead and produce more porosity especially when the travel angle is set at 45. The microstructure observation shows that the formation of martensite and bainite are dominant in heat affected zone of the weldment prepared by lower travel angle. This result is in line with the Charpy impact test result where the toughness of the specimen prepared by lower travel angle shows the lowest toughness. As a consequence of the formation of more fraction of martensite at HAZ, the toughness of the specimen shows the lowest value travel angle at 45.

The objective of the study was to evaluate the influence of syringe and needle sizes on production time and bead size of Lactobacillus plantarum -sodium alginate-banana peel. The bead was produced using the extrusion method. The 25G and 23G of needles produce 0.5 mm to 1 mm and 1 mm to 2 mm bead size, respectively. No different of bead sizes were observed when different syringe size was used. Higher internal diameter of syringe needle and smaller syringe size produced bead in fastest processing time (1 min). The extrusion using 23G syringe needle and 10 ml syringe obtained smallest bead size and fastest processing time. This crucial information could further optimise the extrusion process and future up-scaling process.

Aptamer has been long studied as a substitute of antibodies for many purposes. However, due to the exceeded length of the aptamers obtained in vitro, difficulties arise in its manipulation during its molecular conjugation on the matrix surfaces. Current study focuses on computational improvement for aptamers screening of hepatitis B surface antigen (HBsAg) through optimization of the length sequences obtained from SELEX. Three original aptamers with affinity against HBsAg were truncated into five short hairpin structured aptamers and their affinity against HBsAg was thoroughly studied by molecular docking, molecular dynamics (MD) simulation, and Molecular Mechanics Poisson-Boltzmann Surface Area (MMPBSA) method. The result shows that truncated aptamers binding on HBsAg "a" determinant region are stabilized by the dynamic H-bond formation between the active binding residues and nucleotides. Amino acids residues with the highest hydrogen bonds hydrogen bond interactions with all five aptamers were determined as the active binding residues and further characterized. The computational prediction of complexes binding will include validations through experimental assays in future studies. Current study will improve the current in vitro aptamers by minimizing the aptamer length for its easy manipulation. © 2019 Mohamad Zulkeflee Sabri et al.
