A monolayer film, characterized by the porous crosslinking framework, was fabricated with a designed volume ratio mixture both with colloidal silica suspension and soluble organic polysiloxane. The upper layer for the bilayer film was a hexamethylisilazane (HMDS) modified colloidal silica suspension, leading to the film surface transfer to hydrophobic. The strategic design of nanostructures in the bottom and upper layers resulted in a refractive-index gradient SiO2 film with enhanced AR properties. The bilayer film demonstrated a transmittance of 99.5% at 1064 nm, accompanied by a notable reduction in reflectivity. Moreover, the laser-induced damage threshold of the bilayer film was increased by 30%, rising to as high as 24.7 J/cm2. The SiO2 nanostructured film both showed a refractive-index gradient structure with excellent AR properties and exhibited good laser damage resistance.","PeriodicalId":20324,"journal":{"name":"Polish Journal of Chemical Technology","volume":"57 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141611255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiment was carried out at a wastewater treatment plant in Egypt. Each waste type was mixed with the starter, CaCO3, and water then loaded in a fermenter and kept for 35 days at 35 °C under the anaerobic digestion. The evolved volume of the biogas and the content of methane CH4 were measured daily while the cellulase and protease enzymes were tested every four days. Results have indicated that the digester containing the SS has produced the greatest biogas volume (L) 27.45 Lb/D/d (liters biogas/digester/day), 0.61 Lb/D contents’ volume/d, and cumulative 606.30 Lb/D during the 16th day. Significant CH4 volume percentages produced during the 17th day were 72.07, 71.16, and 71.11% while the produced bio-ethanol alcohol was 2.47, 2.32, and 1.99% from the SS, CD, and PM, respectively. The procedure efficiency is prominent by the production of the biogases and in-situ activating enzymes all in one reactor that was periodically monitored for its reactants and product content. No need for the pre-treatment of wastes as raw materials or chemical additives and the fermented residue can be further tested for soil fertilization. These wastes can be promising for bio-energy production being economic and environment friendly.","PeriodicalId":20324,"journal":{"name":"Polish Journal of Chemical Technology","volume":"30 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141611310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In non-aqueous media, it can be successfully produced via lipase catalysis. This study focuses on the lipase-catalyzed trans-esterification of citronellol alcohol with geranyl acetate ester in a non-aqueous medium to produce citronellyl acetate. For the synthesis of citronellyl acetate, crude acetone powders isolated from several plant seedlings of black cumin, fenugreek, coriander, flax, and rape seed were examined for lipase activity. Black cumin seedling lipase had the highest level of citronella acetate production with a yield of 76.32% in 72 h of reaction time. To assess the impact of different reaction parameters on citronellyl acetate production in organic solvents, hexane was chosen as the best solvent, and black cumin seedling lipase was selected as the best biocatalyst. The highest conversion yield of ester (76.32%) was found when 0.25 M of geraniol acetate and 0.25 M of citronellol reacted at 41 oC after 72 h in the presence of 0.25 g of seedling lipase enzyme in n-hexane. It has been determined that crude black cumin seedling lipase is inexpensive yet effective and has the potential to be used industrially for the synthesis of terpene esters.","PeriodicalId":20324,"journal":{"name":"Polish Journal of Chemical Technology","volume":"17 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141528677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This newly synthesized molecule was subjected to a comprehensive evaluation for both its photophysical and biological applications. Notably, CHP exhibited promising invitro antifungal and antibacterial activities, primarily attributed to the presence of the 4-phenylpiperidin-4-ol moiety and resulting component contributed to an enhanced absorption rate of lipids, thereby improving the pharmacological activity of CHP. This correlation between structure and function was further supported by the outcomes of structure-activity relationship studies. Additionally, we conducted in silico studies to examine the molecular interactions of the synthesized molecule with key proteins, including DNA Gyrase, Lanosterol 14 α-demethylase, and KEAP1-NRF2. The results unveiled robust binding interactions at specific sites within these proteins, indicating potential therapeutic relevance. Furthermore, the photophysical properties of the synthesized compounds were thoroughly investigated using the ab-initio technique. This involved the determination of ground state optimization and HOMO-LUMO energy levels, all calculated with the DFT-B3LYP-6-31G(d) basis set. The assessment of the theoretically estimated HOMO-LUMO value provided insights into the global chemical reactivity descriptors, revealing that the synthesized molecule boasts a highly electronegative and electrophilic index. Taken together, our findings suggest that pyrazole derivatives with 4-phenylpiperidin-4-ol substitutions exhibit promising applications in both photophysical and biological contexts.","PeriodicalId":20324,"journal":{"name":"Polish Journal of Chemical Technology","volume":"19 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141529767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The structural properties of the complex were assessed using elemental analyses, molar conductance, thermogravimetry, UV-Vis, and IR spectroscopies, where the morphological characteristics were evaluated using SEM-EDX and XRD methods. The analyses suggested that two ligand molecules were coordinated to the Ru(III) ion via the nitrogen atoms of piperazine rings. The complex was formulated as [Ru(L)2(Cl)2]Cl, where the Ru(III) ion has a six-coordinate mode, and the coordination sphere is complemented by chlorine atoms. The interaction of the ligand with the Ru(III) ions leads to the product having an organized smooth plate-like structure with a main diameter of 39.42 nm. The RuO2 oxide in the nanoscale range was generated by the thermal decomposition of the [Ru(L)2(Cl)2]Cl complex at 600 oC for 3 hours. SEM micrographs indicated that the RuO2 material possesses uniform and organized microstructures with many internal cavities enabling it to be used as a catalyst for the heterogeneous degradation of dyes and organic pollutants.","PeriodicalId":20324,"journal":{"name":"Polish Journal of Chemical Technology","volume":"31 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140588607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
