INTERACTION AND PROTECTION OF ANTIMICROBIAL COMPOUNDS WITH CARBOHYDRATE-BASED COLLOIDAL SYSTEMS FOR IMPROVED FOOD SAFETY
… (DS) interacts with nisin in a Langmuir monolayer adsorption pattern in both non-emulsion and emulsion systems. The monolayer adsorption capacity (Qm) increased in non-emulsion system and was significantly higher in the emulsion system. At the equivalent concentration of PG-OS (5.0 …

Hydrate Formation Using Dowfax Gemini Surfactants
… gas hydrate formation, first by determining the adsorption isotherms via liquid-liquid titration methods, and then investigating the role in methane hydrate formation in a non-stirred batch reactor. Both surfactants have almost similar structure, sharing doubly charged headgroups, but these …

A study of recognition coating response for quartz crystal microbalances
… exist. BET isotherm plots indicate that heats of adsorption values for the interactions fall within the range of physical adsorption. At high analyte concentrations, PEI coated sensors may behave differently because multilayering interactions increase. At low concentrations, monolayer adsorption …

Preparation and characterization of cross-linked chitosan beads for phosphate adsorption in aqueous solution
… chemical functionalities that affect the adsorption properties. The general features of the adsorption and textural properties of the bead systems were studied using model dye compounds such as p-nitrophenolate (PNP) and phenolphthalein (PHP). The results from the uptake study of the model …

Ultralow interfacial tensions and microemulsion formation in oil-water-surfactant systems
… of the low tensions is thought to be due to monolayer adsorption. Aggregate in equilibrium with the plane monolayer are shown to be spherical microemulsion droplets, whose sizes increase as a minimum in Yc is approached.The results are discussed in terms of the effective molecular geometry of …

HF vapor etching and cleaning of silicon wafer surfaces
… are adsorbed on the oxide surface in sub-monolayer, monolayer, or multilayer films. In the multilayer adsorption regime, the etching rate is usually low (typically 0-400 A/min) and is linearly proportional to the partial pressure of HF and H20. The etching rate in this regime is greatly …

Experimental studies on the adsorption of SO2 on volcanic ashes
The adsorption of SO2 on synthetic and on natural volcanic glasses was studied. The synthetic glasses were of rhyolitic, dacitic and andesitic composition and were synthesized in a high-temperature furnace at 1600°C. The natural volcanic glasses were Lipari obsidian and Puu Waawaa obsidian. Before …
