An intelligent remote prioritization for patients with high-risk multiple chronic diseases is proposed in this research, based on emotion and sensory measurements and multi-criteria decision making. The methodology comprises two phases: (1) a case study is discussed through the adoption of a multi-criteria decision matrix for high-risk level patients;(2) the technique for reorganizing opinion order to interval levels (TROOIL) is modified by combining it with an extended fuzzy-weighted zero-inconsistency (FWZIC) method over fractional orthotriple fuzzy sets to address objective weighting issues associated with the original TROOIL. In the first hierarchy level, chronic heart disease is identified as the most important criterion, followed by emotion-based criteria in the second. The third hierarchy level shows that Peaks is identified as the most important sensor-based criterion and chest pain as the most important emotion criterion. Low blood pressure disease is identified as the most important criterion for patient prioritization, with the most severe cases being prioritized. The results are evaluated using systematic ranking and sensitivity analysis. © 2023 by the authors.

The exploration of the metal–organic framework (MOFs) as a promising alternative for disinfection applications has not yet widely recognized. The flexibility of its structural diversity and large surface area with large pore size allows guest molecules to be stored and their ability to release metal ions has provided great prospect to generate high potent antibacterial activity for environmental applications. In this study, a rapid and straightforward post modification method for zeolitic imidazole framework 8 (ZIF-8) was developed through amine groups' introduction using ammonium hydroxide solution with improved antibacterial properties. The effect of different volume of ammonium hydroxide loadings towards ZIF-8 properties and its antibacterial activity was carefully examined. The result of Fourier transform infrared spectroscopy (FTIR) showed a successful modification of ZIF-8 with amine due to the presence of the N–H group; however, a significant decrease was observed in the BET surface area. The samples' antibacterial potency was tested against Escherichia coli ATCC 11229 and Staphylococcus aureus ATCC 6538 as Gram-negative and positive bacteria type strains, using disc diffusion (DDT) and minimum inhibitory concentration (MIC) testing, respectively. ZNH 20 was found to have the most potent antibacterial efficacy, with the MIC value needed to prevent bacterial growth two times lower than that of unmodified ZIF-8. The presence of positively charged amine groups promotes electrostatic adsorption of negatively charged membrane bacteria cells, which substantially enhanced the antibacterial activity of the modified sample. The synergistic effects of amine groups as well as zinc metal (Zn 2+ ) in the modified ZIF-8 increased the antibacterial activity of the material and thus, making it suitable as antibacterial agents for water purification and biomedical applications.

In this study, we investigated the essential role of feed solution pH so as to gain insights into the transport mechanisms of succinic acid concentration by osmotically-driven forward osmosis （FO） process. FO performances including water flux and bidirectional transport of succinate and chloride anions were systematically examined using cellulose triacetate-based FO membrane. Additionally, real seawater was explored as draw solution. Experimental results revealed that the pH-dependent speciation of succinic acid can affect the FO performances. Ionization of succinic acid at higher solution pH enhanced the osmotic pressure of feed solution, thus leading to lower water flux performance. A strong effect was pointed out on the succinate rejection for which nearly 100% rejections were achieved at pH above its pKa2 value. The rejection of succinate increased in the following order of chemical form： C2H4C2O4H2 〈 C2H4C2OH- 〈 C2H4C2O24-. With real seawater as the draw solution, low to moderate water fluxes （〈4 L. m- 2. h- 1 ） were observed. The divalent succinate anion was highly retained in the feed side despite differences in the succinic acid feed concentration at pH of approximately 6.90.

Clitoria Ternatea is one of the edible and herbaceous flowering plant that has possible health benefits including anti-inflammatory, antioxidants, anti-viral, improving vision, preventing diabetes and protecting against cardiovascular damage. Due to safety concern on synthetic colorant, the demand towards the natural food colorant is increasing. The study focus on microencapsulating Clitoria ternatea extract with maltodextrin by using spray dryer at different inlet temperatures (130°C, 150°C, 170°C and 190°C) to analyze encapsulation yield, encapsulation efficiency as well as simulated release in simulated saliva and simulated gastrointestinal. The results observed spray drying at 190°C has highest powder yield (5.30%) and encapsulation efficiency (72.04%). Rather than conferring protection to anthocyanins, microencapsulation appearred to function more as a delivery method with 23.15%±0.26 of anthocyanins release in simulated release analysis. From the finding, it was concluded that microencapsulation by spray drying at inlet temperature 190°C has been successful used to preserve anthocyanins by protecting bioactive compounds and enhance gastrointestinal delivery performance.

Fourier-transform infrared（FT-IR） spectroscopic experiments were carried out during phosphate adsorption on highly crystalline gibbsite, poorly crystalline 2-line-ferrihydrite and amorphous iron–aluminum–hydroxide mixtures in the molar ratio 1：0, 10：1, 5：1, 1：1, 1：5, 1：10 and 0：1. The OH stretching vibrational bands were utilized to analyze changes in structural and surface OH groups during adsorption, because the position of characteristic P／O vibrational bands can shift depending on reaction conditions, pH or adsorbed phosphate *** and desorption kinetics were studied at pH6 and different initial phosphate concentrations to achieve varying phosphate coverage on the mineral surfaces. For gibbsite the formation of AlHPO4 and Al2HPO4 can be assumed, while for ferrihydrite, a FeHPO4 or Fe2PO4 complex and the precipitation of FePO4 with longer equilibration time were ***2HPO4 or a Fe2PO4 surface complex was deduced for Fe-hydroxides, an AlH2PO4 surface complex was identified for Al-hydroxide, and both displayed either hydrogen bonds to neighboring hydroxyl groups or hydrogen bonds to outer-sphere complexes. Fe：Al-hydroxide mixtures with high Al ratios showed a low phosphate desorption rate, while ferrihydrite and the Fe：Al-hydroxide mixtures with high Fe ratios had almost negligible desorption rates. It was concluded that within the weakly associated amorphous FeO（OH） materials, FePO4 precipitated, which was bound by outer-sphere hydrogen bonds. With high Al ratios, desorption increased, which indicated weaker phosphate binding of both inner-sphere and outer-sphere complexes and hence, either no or minor quantities of precipitate. Ferrihydrite showed a more rigid structure and a lower extent of precipitation compared to amorphous Fe-hydroxide.

Blending hydrogen into natural gas pipelines is a promising pathway to reduce greenhouse emissions but heightens safety risks due to hydrogen’s low ignition energy and wide flammability range, which intensify fire and explosion hazards. Traditional suppressants are less effective for hydrogen-mixed combustion, demanding advanced suppression technologies and revised safety protocols to manage these risks effectively. This study evaluated C₃F₇COC₂F₅ as a potential fire suppressant for hydrogen-doped natural gas systems experimentally and computationally. Explosion experiments in a premixed deflagration tube revealed dual effects of C₃F₇COC₂F₅: at 1% suppressant and equivalence ratio Φ = 0.6, maximum explosion pressure increased, while ≥ 2% suppressant or Φ ≥ 0.7 inhibited combustion. Then, chemical kinetic simulations and density function theory calculations showed a low suppressant enhances •OH generation, accelerating exothermic reactions via lower energy barriers. Conversely, a high suppressant slows •OH/•H production and releases fluorine radicals (•F), which scavenge reactive species (•H, and •OH) through electron-withdrawing effects, suppressing flame propagation. The findings clarify the concentration-dependent promotion/inhibition mechanisms of C₃F₇COC₂F₅, guiding safer hydrogen-blended natural gas applications for the fire protection and environmental protection community when choosing it as a possible suppressant.

Aquaculture wastewater contains high levels of organic matter and nutrients, which can be harmful to aquatic life if discharged improperly into surface water bodies. Coagulation-flocculation is currently the best practice for treating aquaculture effluent with biocoagulants, offering an alternative to metal-based coagulants. This study aims to investigate the potential of Tamarindus indica seeds as a biocoagulant for treating aquaculture wastewater, focusing on the optimal solvent extraction, concentration, and dose. This study also examines the toxicity of biocoagulants to aquatic organisms. Coagulation-flocculation study was conducted under jar test experiment with NaCl, NaOH, and HCl used as solvents; concentration of 0-10 g/L; and doses of 1-5 % v/v under 120 rpm (rotation per minute) rapid mixing for 1 min, 20 rpm slow mixing for 20 mins, and 60 mins sedimentation time. A characterization study showed that NaCl-treated T. indica has a positive zeta potential charge, attributed to the presence of hydroxyl, carbonyl, and amide functional groups. Under this optimum condition (NaCl-extract, 6 g/L, and 4 % v/v), the biocoagulant achieved high removal (>50 %) of turbidity, TSS (total suspended solid), and ammonia and considerably good removal of other parameters (TN [total nitrogen], BOD 5 [biological oxygen demand], COD [chemical oxygen demand]). The toxicity test revealed that no mortality was observed at a concentration of 1 g/L, whereas 10 g/L resulted in a 100 % mortality rate after 24 hours of exposure. Further toxicity analysis is suggested to be conducted using treated final effluent (not directly using biocoagulant substances) to observe the direct impact of the treated wastewater if discharged into the water bodies.

Purple sweet potato ( Ipomoea batatas ) is one of nutritious food. Through deep-frying process, purple sweet potato chips that currently been introduced on the market, worldwide and being public demand nowadays. However, the frying process caused the increasing of lipid content in the food. Edible coating method is applied in improving the fried chips characteristics. Thus, this study was performed to determine the effect of calcium chloride (CaCl 2 ) concentration (0.01, 0.05 and 0.1 M) and maltodextrin (3%) as the edible coating on the purple sweet potato chips. Coated-purple sweet potato chips were prepared by dipping method. It was followed by the analysis which were lipid uptake and moisture contents, texture (hardness) examination, image capture and sensory evaluation. Subsequently, the obtained data were analysed using one-way ANOVA and Duncan multiple range. Based on the results, lipid uptake was slightly reduced in the 0.1M CaCl 2 -coated chips but still not significantly different compared to other chips. Moisture content became higher as the concentration of CaCl 2 increased. In addition, the hardness of all coated chips were higher compared to the uncoated sample. Similar colour values were demonstrated in all samples. In sensory evaluation, most preferable sample from the consumers was 0.1M CaCl 2 -coated chips. This coating agents (0.1M CaCl 2 with 3% maltodextrin) enhanced the characteristics such as lipid reduction and sensory’s overall acceptability of the purple sweet potato chips.

Deep fried-based food is commonly consumed in Malaysia due to their tasty and good appearance of the food. However, high consumption of the food may lead to adverse effect to consumer’s health beside high usage of oil-palm based cooking oil in deep frying process. Thus, this research aimed to investigate the effect of edible coating using different pectin concentration (1%, 2% or 3%) on cassava chips. Coated-cassava were prepared through dipping method into pectin and calcium chloride solution. Series of analysis such as lipid determination, texture analysis, colour determination, FTIR analysis, sensory evaluation and statistical analysis were conducted. Highest pectin concentration which 3% pectin-coated chips proved to reduce highest lipid uptake up to 11.750 ± 0.076 compared to uncoated chips (52.360 ± 0.762). For colour determination, it showed that the pectin coating did not changed the initial colour of the chips and enhanced the colour brightness after frying. Between all samples, the control or uncoated chips has the lowest result for hardness which was 577.216 ± 95.194 while 3% pectin coated chips had highest values in term of hardness which were 1338.209 ± 246.900. FTIR was able to recognize presence of the (N-O) group in all coated cassava chips compared to uncoated chips. The uncoated and pectin-coated chips had no significance different in overall acceptance in sensory analysis. This research concluded that edible coating from pectin with 3% concentration was able to reduce lipid uptake and enhanced several characteristics in cassava chips. Newly developed value-added coated cassava chips would offer a healthy, tasty and better appearance snack to consumer.
