In this study, several room-temperature ionic liquids (RTILs) with an imidazolium-based cation of 1-butyl-3-methylimidazolium [bmim]+ and anions of bis(trifluoromethylsulfonyl)imide [TFSI]−, trifluoromethanesulfonate [OTf]−, hexafluorophosphate [PF6]−, and tetrafluoroborate [BF4]− were incorporated into UiO-66 by wet impregnation method under air. The RTILs/UiO-66 composites were characterized by PXRD, FTIR, TGA, nitrogen physisorption, and CO2 adsorption. Based on the type of anions of imidazolium-based RTILs, the CO2 uptake of RTILs/UiO-66 composites followed the trend: [OTf]− > [TFSI]− > [PF₆]− > [BF₄]− at low temperature (273 K) and pressure (100 kPa). The CO2 uptake of pristine UiO-66 increased approximately 1.5 times upon incorporating [bmim][OTf]. The type of anions of imidazolium-based RTILs influences the CO2 adsorption performance of RTILs/UiO-66 composites in which anions containing fluoroalkyl group ([OTf]−, [TFSI]−) exhibited a higher CO2 uptake compared to inorganic fluorinated anions ([BF4]−, [PF6]−). Hence, the incorporation of hydrophobic imidazolium-based RTILs showed a potential to enhance the performance of UiO-66 for CO2 adsorption application.","PeriodicalId":13515,"journal":{"name":"Indonesian Journal of Chemistry","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136114342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, commercial rapid tests may be limited in their ability to detect pathogen variants across different countries. It was found that the sensitivity of a chikungunya rapid test on local strain was only 20.5% as compared to the East, Central, and South Africa (ECSA) phylogroup. Therefore, the development of geographically specific diagnostics is essential. Investigating the distinctive structural properties of a locally sourced antigenic protein is an important initiative for the development of a specific antibody. This study utilized structural bioinformatics and molecular dynamics simulations to investigate the differences between the E1-E2 antigenic proteins of the Indonesian chikungunya virus (Ind-CHIKV) and that of ECSA. The results showed that some of the mutation points are located at the antibody binding sites of Ind-CHIKV. G194S and V318R mutations were proposed as distinctive features of Ind-CHIKV, leading to weaker antibody binding compared to ECSA. It suggests that modifying the antibody to accommodate bulkier side chains at positions 194 and 318 could improve its effectiveness against Ind-CHIKV. These insights are valuable for developing a highly sensitive immunoassay for Ind-CHIKV and other regional pathogens, ultimately enhancing diagnostic capabilities in Indonesia.","PeriodicalId":13515,"journal":{"name":"Indonesian Journal of Chemistry","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136113090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Appropriate parameters were investigated, including the ion SbI42− concentration and the pH value of the complex formation.

Precision, accuracy, detection limit, and RSD %, as well as relative standard deviation (n = 5), were calculated. The test sensitivity was 0.013 µg cm−2. Several interference additives were studied by investigating the effect of equal and duplicate quantities of some common excipients on selectivity, such as starch, glucose, lactose, glycerin, and talc.

CA was synthesized by the Fischer esterification mechanism and the PVDF membrane was fabricated using the phase inversion method with 0.3% CA concentration. FTIR analysis of CA shows an absorption at 1700 cm−1 suggesting that the hydroxyl group of cellulose had been successfully substituted with an ester group (C=O), and CA has a high degree of substitution (DS) value of 3.50. Adding CA improved the hydrophilicity and anti-fouling properties of up to 86.45% of PVDF membranes. Furthermore, CA increased the value of water permeability 2–3 times than pristine PVDF membrane. The presence of CA enhanced the porosity of the PVDF membrane, which promoted the membrane's effectiveness for MB filtering. As a result, CA from screw pine leaf cellulose has promising features as a filler for PVDF membranes and potential dye filtration.","PeriodicalId":13515,"journal":{"name":"Indonesian Journal of Chemistry","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136113077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Candlenut oil (Aleurites moluccana L.) is one of the non-edible oils which can be used as feedstock for biodiesel production since they have a high oil content. Herein, the biodiesel production from candlenut oil has been conducted using zinc oxide (ZnO) synthesized by the polyol method. Polyol methods facilitated the formation of ZnO nanoparticles with various shapes, including spherical, rod, and hexagonal. Besides, ZnO showed a mesoporous characteristic, facilitating the conversion of fat fatty acid to fatty acid methyl ester (FAME) of 61%. Increasing ZnO dosage led to enhancing the FAME yield. Similarly, the FAME yield was also improved by increasing the reaction time. The results of esterification of candlenut oil and methanol yielded 70.76% FAME with 2% nano-ZnO polyol catalyst at 180 min reaction time at room temperature whilst being stirred constantly at 400 rpm. A good FAME conversion using ZnO at room temperature provides good information to produce biodiesel with a simple method. Apart from that, photocatalytic promoted transesterification at room temperature, which is beneficial for reducing energy consumption.","PeriodicalId":13515,"journal":{"name":"Indonesian Journal of Chemistry","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136113833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
