Thermal Characterization of Phase Change Materials by Differential Scanning Calorimetry: A Review

open access: yesApplied Sciences, 2022
The use of phase change materials (PCMs) in thermal energy storage (TES) applications as a system that can fill the gap between the energy supply and demand has sharply increased over recent years.

Characterization of ß-trypsin at acid pH by differential scanning calorimetry

open access: yesBrazilian Journal of Medical and Biological Research, 2003
Trypsin is a serino-protease with a polypeptide chain of 223 amino acid residues and contains six disulfide bridges. It is a globular protein with a predominance of antiparallel ß-sheet and helix in its secondary structure and has two domains with ...

Kinetics of isothermal and non-isothermal precipitation in an Al-6at%Si alloy [PDF]

open access: yes, 1998
A novel theory which describes the progress of a thermally activated reaction under isothermal and linear heating conditions is presented. It incorporates nucleation, growth and impingement and takes account of temperaturedependent solubility.

High-Resolution Adiabatic Calorimetry of Supercooled Water [PDF]

open access: yes, 2018
Liquid water exhibits anomalous behavior in the supercooled region. A popular hypothesis to explain supercooled water's anomalies is the existence of a metastable liquid-liquid transition terminating at a critical point. The hypothesized phase transition is not directly accessible in a bulk experiment because it is expected to occur in "no-man's ...

Glass Transition Temperature Depression at the Percolation Threshold in Carbon Nanotube-Epoxy Resin and Polypyrrole-Epoxy Resin Composites [PDF]

open access: yes, 2005
The glass transition temperatures of conducting composites, obtained by blending carbon nanotubes (CNTs) or polypyrrole (PPy) particles with epoxy resin, were investigated by using both differential scanning calorimetry (DSC) and dynamical mechanical ...

Mechanics from Calorimetry: A New Probe of Elasticity for Responsive Hydrogels [PDF]

open access: yesPhys. Rev. Applied 8, 014003 (2017), 2016
Temperature-sensitive hydrogels based on polymers such as poly(N-isopropylacrylamide) (PNIPAM) undergo a volume phase transition in response to changes in temperature. During this transition, distinct changes in both thermal and mechanical properties are observed.

Glass transition investigated by a combined protocol using thermostimulated depolarization currents and differential scanning calorimetry [PDF]

open access: yes, 2009
Relaxation times of bisphenol A polycarbonate around the glass transition temperature are estimated using the combination of differential scanning calorimetry (DSC) and thermostimulated depolarization currents (TSDC). These measurements are performed
