The syntheses, structure solutions, and physicochemical and catalytic characterizations of the novel zeolites SSZ-53 and SSZ-59 are described. SSZ-53 and SSZ-59 were synthesized under hydrothermal conditions with the [1-(4-fluorophenyl)cyclopentylmethyl]trimethyl ammonium cation and 1-[1-(4-chlorophenyl)cyclopentylmethyl]-1-methyl azocanium cation, respectively, as structure-directing agents. T...

Current waste management policies favor biogases (digester gases (DGs) and landfill gases (LFGs)) valorization as it becomes a way for energy politics. However, volatile organic silicon compounds (VOSiCs) contained into DGs/LFGs severely damage combustion engines and endanger the conversion into electricity by power plants, resulting in a high purification level requirement. Assessing treatment...

The metal-water interaction strength (»hydrophilicity«) plays a major role in deterrnining both the structure of the interfacial region and the energetics of adsorption phenomena. A »hydrophilicity« scale can be established on the basis of a phenomenological approach for a series of sp-metals. It is shown that recent results for sd-metals (Cu, Ag, Au) cannot be organized in the same picture. Th...

The relationship between physicochemical properties of biochar-based activated carbons and its adsorption was investigated using an aromatic model compound, phenanthrene. Solid-state (13)C NMR analysis indicated more condensed aromatic structures when pyrolysis temperature increased or after activation process induced. The increasing aromaticity and non-protonated carbon fraction of the activat...

Many gaseous markers of critical biological, physicochemical, or industrial occurrences are masked by the cross-sensitivity of the sensors to the other active components present at higher concentrations. Here, we report the strongly selective diffusion and drift of contaminant molecules in air-filled conductive polymer-coated microfluidic channels for the first time. Monitoring the passage of d...

This study was conducted to evaluate factors regulating groundwater quality in an area with agriculture as main use. Under this study twelve groundwater samples have been collected from Padra taluka, Dabhoi taluka and Savli taluka of Vadodara district. Groundwater samples were chemically analyzed for major physicochemical parameter in order to understand the different geochemical processes affe...

Process waters in deinking mills often feature a strong coloration, due to dyes and pigments released from the recovered paper. This can usually be remediated by pulp bleaching treatment with appropriate chemicals. However, the red shade (from rhodamine dye) is resistant to conventional bleaching treatments. This largely limits the use of deinked pulp in white paper grades. In this review, the ...

This study tackles the interaction between gold surfaces and two peptide fragments named NGF(1-14) and BDNF(1-12), able to mimic the proliferative activity of the nerve growth factor (NGF) and the brain derived neurotrophic factor (BDNF), respectively. The physical adsorption processes on the solid surface from both single and binary peptide solutions, at physiological and acid pH, were investi...

Chitosan-coated curcumin nanoliposomes (CS-Cur-NLs) were fabricated by the ethanol injection method (EIM), and their physicochemical properties were compared with the properties of those fabricated by the dry thin film method (DTFM). The mean size and zeta potential of CS-Cur-NLs gradually increased with CS concentration. The encapsulation efficiency of Cur-NLs prepared by EIM was 54.70%, which...

Peanut protein and its hydrolysate were compared with a view to their use as food additives. The effects of pH, temperature and protein concentration on some of their key physicochemical properties were investigated. Compared with peanut protein, peanut peptides exhibited a significantly higher solubility and significantly lower turbidity at pH values 2-12 and temperature between 30 and 80°C. P...
