Heterogeneous catalysis in the different reactor types on the examples of ethyl benzene to styrene, methane dehydroaromatization and propylene carbonate, methanol transesterification
… to find a way to produce the “green” reagent, dimethyl carbonate (DMC), through transesterification of propylene carbonate (PC) and methanol in the vapor phase. The importance of DMC for the development of variety of green syntheses is widely described. The reaction conditions and the catalyst …

Demonstrating the feasibility of polyethylene passive samplers for quantitative assessment of volatile organic compounds in soil
… sites. Motivated by the successful use of polyethylene (PE) passive samplers in sediments, this research focused on demonstrating the feasibility of PE samplers to accurately assess volatile organic compounds in soil vapors. Experimental values of PE-water partitioning coefficients (Kpew) for …

Metal organic frameworks as sorbents for volatile organic compounds
… high vacuum and exposed to a known pressure of benzene, toluene, ethyl benzene, and the xylene isomers (BTEX). The Henry’s constant, which describes the adsorption capacity for each MOF, was calculated from the mass change during the adsorption isotherm at 30°C, 25°C, and 20°C. The enthalpy of …

Molecular genetics and microbiology of bioremediation using methane-oxidising bacteria
… as their sole source of carbon and energy. Methylosinus trichosporium OB3b is a Gram negative, methanotrophic bacterium, which can convert methane to methanol by either particulate (pMMO) or soluble (sMMO) methane monooxygenase. The sMMO comprises three polypeptides; hydroxylase (αβγ)2, …

A Gas Sensor for the Selective Detection of Volatile Organic Compounds
… VOCs. In this context, the VOCs of interest were benzene, toluene, ethyl benzene, para-xylene (BTEX), due to their proven toxicity and prevalence in human environments. With the aim of producing a potentially deployable device, a novel sensing platform was designed and constructed. The main …
