This study models the phase equilibria of sulphur compounds – SO2, H2S, and COS in mixtures relevant to carbon capture storage (CCS). The modelling tool used this investigation is cubic plus association (CPA) equation state. Modelling binary multicomponent these with CO2, water, glycols, methane, other inert performed. Different approaches are considered mixtures. Sulphur treated as non-associa...

The embedding and sectioning of tissues in paraffin is a slow process. For histochemical purposes, especially for the demonstration of enzymes, preparation of tissue sections in paraffin is not desirable since the exposures of tissues to high temperatures and to several changes of dehydrating and clearing agents are detrimental to the preservation of enzymes. Gomori's (1946) experience with the...

The aerobic and anaerobic biodegradation of polyethylene glycols (PEGs) in a model wastewater was investigated employing sludge microbes from Xiamen Terylene plant. The effect of molecular weight (MW) on the aerobic/anaerobic biodegradation of PEGs was assessed by performing shake flasks/sealed flasks experiments, respectively, using organic model wastewater containing PEG 600, 6000 and 20,000....

The apparent solubilities of various proteins (14,000 to 670,000 daltons) were measured in the presence of polyethylene glycols (PEGS) of different sizes. All of the solubility curves, determined by measur ing the protein concentration in the supernate of centrifuged mixtures, exhibited the characteristic linear dependence of log S (g/liter) on PEG concentration (%, w/v). For human albumin in P...

The optical properties of single colloidal semiconductor nanoparticles (NPs) are considerably influenced by the direct environment of the NPs. Here, the influence of different liquid and solid glycol matrices on CdSe-based NPs is investigated. Since the fluorescence of individual NPs varies from one NP to another, it is highly desirable to study the very same individual NPs in different matrice...
