In the production process of briquette biofuel, terpenes such as pinene and camphene, well non-terpenoid VOCs formic acid, acetaldehyde, benzene, are generated during conditioning, drying other procedures. Different catalysts Fe 3 O 4 supported by CoFe-ZIFs were prepared thermal dissolution method microwave with changing doping amount iron. The structures these characterized X-ray Diffraction (...

Thermodenuding particles can provide insights into aerosol composition and may be a way to create particles in laboratory chambers that better mimic the atmosphere. The relative volatility of secondary organic aerosol (SOA) was investigated by evaporating organics from the particles using a thermodenuder (TD) at temperatures between ∼ 60 and 100 C. Volatility was influenced by the parent hydroc...

An Aerodyne Aerosol Mass Spectrometer (AMS) has been utilised to provide on-line measurements of the mass spectral signatures and mass size distributions of the oxidation products resulting from irradiating 1,3,5trimethylbenzene (1,3,5-TMB) and α-pinene, separately, in the presence of nitrogen oxide, nitrogen dioxide and propene in a reaction chamber. Mass spectral results indicate that both pr...

The inhibition of enzymes involved in the breakdown of carbohydrates is considered a therapeutic approach to the management of type-2 diabetes. This study sought to investigate the effects of essential oil from clove bud on α-amylase and α-glucosidase activities. Essential oil from clove bud was extracted by hydrodistillation, dried with anhydrous Na2SO4 and characterized using gas chromatograp...

Abstract In this paper we aim to highlight the need consider possible role of autocatalysis in oxidation reactions when using molecular oxygen as terminal oxidant. Oxygen its ground state is a diradical, and depending on reaction conditions, it can initiate through radical pathways mechanisms which do not require presence catalyst. Consequently, contrast benzyl alcohol with α-pinene. For initia...

Nepeta species are widely used in folk medicine as a diaphoretic, diuretic, antiseptic, astringent, anti-asthmatic, cough suppressant, antispasmodic, antipyretic, sedative and stomachic. This study was designed to examine the chemical composition of essential oil isaurica sulfuriflora. It determined that aerial parts N. plant contained 0.72% oil, 37 compounds were identified representing 98.86%...

Oleoresin samples collected from Pinus sylvestris L. trees from Acıpayam, Çal and Çamlıbel, three different locations in Denizli-Turkey. The constituents of the turpentine oil, obtained by hydrodistillation of oleoresin of Pinus sylvestris L., were identified by GC-MS. Fifty four constituents were detected from the turpentine oil, which constituted about between 96.2% and 98.2% of the total amo...

The present study was designed to determine the effects of the essential oil of Laurusnobilis L. (Lauraceae) and its three main components on α-glucosidase and reactive oxygenspecies scavenging activity. The chemical composition of the essential oil from Laurus nobilisL. leaves was analyzed by GC/GC-MS and resulted in the identification of 29 compounds,representing 99.18% of the total oil. 1,8-...
