The effect of acid mixtures on biomass cellulose poly (Furfuryl) alcohol nanocomposites
Recently, extraction of cellulose nanocrystals (CNCs) via acid hydrolysis using sulphuric acid has been intensively studied. Moreover, the use of sulphuric acid requires shorter hydrolysis time, while producing stable suspensions with high yield and crystallinity. However, it results in CNCs with …

SYNTHESIS AND CHARACTERIZATION OF BIODIESEL FUELS FROM FURFURYL ALCOHOL AND SPENT COFFEE GROUNDS
… (H<sub>2</sub>SO<sub>4</sub>). Fatty acid furfuryl esters (FAFurEs) were produced using commercially-purchased cooking oils (canola, olive, corn, sunflower, and peanut) with furfuryl alcohol, a basic (K<sub>2</sub>CO<sub>3</sub>) catalyst, a co-solvent (THF), and an ionic liquid …

Understanding the Kinetics and Mechanisms of the Desired and Undesired Reactions during Electrochemical Hydrogenation and Hydrogenolysis of Furfural on Copper in Acidic Media
… of the process. Two products are formed, furfuryl alcohol and 2-methylfuran. Furfuryl alcohol is used to produce resins for the foundry industry and 2-methylfuran has been identified as a high-octane fuel. Mathematical models were developed which showed that furfuryl alcohol and …

Isolation and Characterization of Bioactive Metabolites from Endophytic Fungi of Pinus Strobus
… (2), one glucopyranosol derivative (3), one furfuryl ether derivative (4), four dihydrobenzofurans derivatives (5-8), one xanthene derivative (9), and one polyoxygenated cyclohexene (10). Two of the dihydrobenzofurans compounds are new (7 and 8), while the other two (5 and 6) are reported …

Intramolecular [4+2] cycloadditions of conjugated ynones and related species ; Studies directed toward the total systhesis of glycinoeclepin A
… an unusual rearrangement leading to a 3-furfuryl carbene. A 1,2-C-H insertion then produces the polycyclic furan product. A detailed analysis of the scope and mechanism of this reaction is presented. The synthetic utility of the method for the synthesis of complex organic molecules is …

The ultra-selective hydrogenation of Furfural on PtCu supported bimetallic nanoparticles and on Pt(111) under ultra-high vacuum
… as well as achieving high selectivities towards furfuryl alcohol, surpassing the behaviour of pure Pt catalyst across 3 different pressures. Finally, Single Atom Alloys (SAA), formed via the galvanic replacement of dispersed host Cu nanoparticles by Pt was investigated. Pt:Cu nanoparticles with …

Generation of Biomarkers from Anthrax Spores by Catalysis and Analytical Pyrolysis
… acetamide, diketopiperazines, fatty acids, furfuryl alcohol, and DNA bases. A statistically designed factorial study was used to determine the importance of temperature, spore loading, and nanocluster loading on the production of three important biomarkers. The relative importance of these …

Response of DNA repair and replication systems to exocyclic nucleic acid base damage
… was found that DinB could in fact bypass the N2-furfuryl-guanine lesion and its saturated homolog in vivo. The second part of this work describes how we systematically investigated the role that the distance from an origin of replication may have in the mutagenesis of an adduct. Our hypothesis …

Preparation and properties of carbamates, nitrocarbamates and their derivatives
… material. Attempts at nitrating ethyl N-(2-furfuryl) carbamate and ethyl N-(2-thenyl) carbamate resulted in the formation of dark, viscous tarry substances. However ethyl N-(2-pyridyl) carbamate and ethyl N-(3-pyridyl) carbamate were nitrated in the nucleus by refluxing them with a mixture …
