“Quasi-isothermal” thermogravimetry
Analytica Chimica Acta, 1971A new method has been worked out which allows the implementation of a special heating program according to which the temperature of the sample is rapidly increased so long as no changes occur in it, while it ensures nearly isothermal conditions when reactions connected with weight change are taking place.

Physical Review E, 2002
The existence of steady, spherically symmetric wave fronts ("isothermal flame balls") in chemical reaction systems exhibiting autocatalysis is demonstrated. Such solutions require relatively high kinetic orders p with respect to the autocatalytic species, with p>5, but occur even with equal diffusion coefficients. The flame balls are unstable, but have

Quantitative Characterization of Adsorption Isotherms Using Isothermal Microcalorimetry
Journal of Pharmaceutical Sciences, 1996The integral heat of adsorption of water vapor on sodium benzoate samples was determined at various partial vapor pressures using a heat conduction microcalorimeter. An equation is presented to describe the calorimetric integral heat response (mJ/g of solid) as a function of relative humidity.

ISOTHERMAL AND NON-ISOTHERMAL MULTICOMPONENT ADSORPTION KINETICS
Chemical Engineering Communications, 1990The model equations in the relaxation form for the multicomponent kinetics of isothermal and non-isothermal adsorption, taking into account all major distinctive features of the interphase heat and mass exchange inside porous grains and at their surface (see points 1 to 4 below) for P (“pore”) and S (“solid”) models of mass transfer within porous ...

Isothermal Titration Calorimetry
2021Calorimetry is a classical biophysical method that by definition measures heat. In isothermal titration calorimetry (ITC), the heat is the result of titrating interacting components together and allows direct determination of the thermodynamics for this process.

Isothermal and non‐isothermal crystallization behavior of PET nanocomposites
Polymer Engineering & Science, 2011AbstractPolyethylene terephthalate (PET)/clay nanocomposites (PCNs) containing 1 wt% Cloisite 30B (C30B) were prepared via melt compounding. Modulated differential scanning calorimetry (MDSC) for isothermally crystallized samples revealed that the third endotherm at the highest temperature may be attributed to the recrystalization and melting of ...

Isothermal Titration Calorimetry
2005Isothermal titration calorimetry is an ideal technique for measuring biological binding interactions. It does not rely on the presence of chromophores or fluorophores, nor does it require an enzymatic assay. Because the technique relies only on the detection of a heat effect upon binding, it can be used to measure the binding constant, K, the enthalpy ...

Adsorption isotherms—A critique
Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1973Summary The possibility or the impossibility of separating the particle and the electrode interactions is discussed in a wider context of the effects due to any two interaction potentials on the equation of state. The involved nature of the pressure dependence on two individually definable forces is illustrated through the Percus Yevick results for ...

Relationship between non-isothermal transformation curves and isothermal and non-isothermal kinetics
Acta Materialia, 2005A mathematical method is presented to obtain an isothermal transformation curve from a continuous cooling transformation (CCT) curve. It can also be used for transformations that occur during continuous heating rather than continuous cooling. The method is applied to nucleation and growth transformations and to grain growth.

Binding isotherm determination by isothermal titration calorimetry
Journal of Thermal Analysis and Calorimetry, 2004A simple method for determination of binding isotherm in the protein-ligand interaction was introduced using isothermal titration calorimetric data. This general method was applied to the study of the interaction of myelin basic protein (MBP) from bovine central nervous system with divalent copper ion at 27°C in Tris buffer solution at pH=7.2.
