The solubility of alkylthiol-coated silver nanoparticles and the energetics of the ligand disordering have been investigated. Calorimetry measurements have provided correlations between the nature of the ligands and the enthalpy of the ligand disordering, ...
Calorimetry (adiabatic, isothermal, differential, oscillating or acoustic) is generally based on heat-flow measurements of the studied system. Most of its applications are dedicated to kinetic-parameter detn., safety studies and process optimization, phase ...
The heat flow reaction calorimetry technique was developed for reactions with supercrit. fluids and was applied to monitor the free-radical dispersion polymn. of Me methacrylate in supercrit. carbon dioxide (scCO2). The main math. equation for the calorime ...
Following several tragic chemical accidents that have occurred in recent years, some directives concerning chemical process safety have been issued. The Seveso directive, for example, requires a precise description of the consequences of a possible chemica ...
Supercritical carbon dioxide (scCO2) is a promising foaming agent for the production of polymeric foams, representing an environmentally friendly alternative for the foaming agents currently used. During the expansion phase of the scCO2-foaming process, te ...
Driven by the need for more cost-effective applications, researchers and design engineers of polymer composites are facing increasing demands for the development of faster and more environment-friendly processing methods. Rapid processing techniques requir ...
The focus of this thesis was on the mechanisms of release of volatile molecules from smectite clay minerals. The weight loss was monitored by thermogravimetry, differential calorimetry, and mass spectrometry under isothermal conditions and under ramp tempe ...
A unique bench-scale heat flux calorimeter is described, which is capable of detecting the low heat signal of an animal cell culture (a max. of 200 mW/l is produced with a batch culture of SF9 insect cells). After the tech. modifications that enhanced the ...
A review, with .apprx.43 refs. A review of different types of biol. reaction calorimetry systems currently used together with the operating principles is presented. The av. resoln. of these systems is approx. 20 to 1000 mW l-1, sufficient for studies of a ...
