We examine mixture separations with microporous adsorbents such as zeolites, metal-organic frameworks (MOFs) and zeolitic imidazolate frameworks (ZIFs), operating under conditions close to pore saturation. Pore saturation is realized, for example, when separating bulk liquid phase mixtures of polar compounds such as water, alcohols and ketones. For the operating conditions used in industrial pr...

Saturation mutagenesis was used to generate 10 mutants of toluene-o-xylene monooxygenase (ToMO) at alpha subunit (TouA) positions A101 and A110: A101G, A101I, A101M, A101VE, A101V, A110G, A110C, A110S, A110P, and A110T; by testing the substrates toluene, o-cresol, m-cresol, p-cresol, phenol, naphthalene, o-methoxyphenol, m-methoxyphenol, p-methoxyphenol, o-xylene, and nitrobenzene, these positi...

the conversion of the cellulose into 5-hmf would experience three steps, cellulose to glycose, glycose to fructose and fructose to 5-hmf. chloride ion can break down the hydrogen bond in cellucose, chromium can catalyze the isomerization of glycose to fructose, and the high temperature is helpful to cyclohydration of fructose to 5-hmf. in this paper, the sawdust has been directly degraded into ...

The cataluminescence (CTL) of benzene and the benzene homologues toluene and xylene on nanosized γ–Al2O3 doped with Eu2O3 (γ–Al2O3/Eu2O3) was studied and a sensor of determining these gases was designed. The proposed sensor showed high sensitivity and selectivity at an optimal temperature of 432 oC, a wavelength of 425 nm and a flow rate of 400 mL/min. Quantitative analysis was performed at the...

introduction: due to side effects of antiinflammatory drugs such as dexamethasone and indomethacin, there is a less tendency to use them. on the other hand, the use of medicinal plants has been common in the treatment of inflammation since ancient times and also, using of the plants is increasing. present research investigated the antiinflammatory effect of the hydroalcoholic extract of capitol...

The urea adduct with the guests of m-nitrobenzoic acid, m-nitroaniline and p-xylene mixtures by adductive crystallization was successfully grown by slow evaporation method. The single crystals obtained were non-hygroscopic and good in size. The crystal structure of the grown crystal has been determined, and it belongs to the monoclinic system with centrosymmertic space group P21/c. Fourier tran...

Sphingobium yanoikuyae B1 can utilize biphenyl, naphthalene, phenanthrene, toluene, and m-/p-xylene as sole sources of carbon and energy. Here, we present a 5.2-Mb assembly of its genome. An analysis of the genome can provide insights into the mechanisms of polycyclic aromatic hydrocarbon (PAH) degradation and potentially aid in bioremediation applications.
