Abstract Baseline correction is a key step in processing of thermal analysis data. Whilst this common step, techniques range from linear baselines to use high‐order polynomials. When considering formal baseline (those without physical or experimental justification), only methods should be used: with time, temperature, and extent reaction. The absence also considered. An silico study shows that ...

Common heat transfer fluids such as water, ethylene glycol, and engine oil have limited heat transfer capabilities due to their low heat transfer properties. Nanofluids are suspensions of nanoparticles in base fluids, a new challenge for thermal sciences provided by nanotechnology. In this study, we are to optimize and report the effects of various parameters such as the ratio of the thermal co...

Differential scanning calorimetry (DSC) belongs to the family of thermal analysis methods. In general thermal analysis is the determination of substance properties in dependence on temperature. Thermodynamic data (heat capacity, phase transition, enthalpy) and kinetic data can be determined by methods of thermal analysis. The greatest advantage of thermal analysis is the easy handling and the o...
