Dsc 60 plus

Powder crystallinity was studied by differential scanning calorimetry using a Shimadzu DSC-60 Plus differential scanning calorimeter equipped with a TA-60WS thermal analysis system and the TA-60WS version 2.21 software (Shimadzu Corporation, Kyoto, Japan). The test powder samples were heated in aluminum pans under nitrogen purge from 30 °C to 330 °C at a heating rate of 3 °C/min. The measurements were conducted in duplicate.

For determining the phase transformation temperatures and the Curie temperature (T_c) during both heating and cooling, differential scanning calorimetry (DSC; DSC-60 Plus, Shimadzu Corporation, Kyoto, Japan) was utilized. The HT alloys were utilized as testing specimens while the Al₂O₃ powders with a certain weight were used as reference materials. A high-purity Ar atmosphere was used during the thermal analysis for preventing the oxidation reaction of the specimens at an elevated temperature. The temperature scan was from 273 K to 383 K at a scan rate of 10 K min⁻¹.

Thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) were performed on npBX and npBL. Samples were placed in an alumina crucible and subjected to thermal gravimetric analysis (Shimadzu^®, model TGA 51, Kyoto, Japan) with a temperature range from 27 °C up to 1200 °C with an incremental increase in heat of 10 C/min in an inert nitrogen atmosphere at a gas flow of 50 mL/min. For DSC analysis (Shimadzu^®, model DSC 60 PLUS), samples were packed into an aluminum pan, heated up to 90 °C, cooled to room temperature and then heated again up to 600 °C (with the heat increasing at a rate of 10 °C per minute) in an inert nitrogen atmosphere at 50 mL/min.

The thermal properties of collagen films were characterized by a DSC-60plus (Shimadzu, Kyoto Japan), according to a previously published method with a slight modification [43 (link)]. Prior to measurement, the film was dehydrated in a desiccator equipped with blue silica gel for 2 weeks, 3 mg of samples were weighed accurately into aluminum pans and sealed, and then scanned from 25 °C to 90 °C with a heating rate of 10 °C/min. An empty aluminum pan was used as a control. The maximum denaturation temperature was recorded as the temperature of each endothermic peak.

The DSC measurements of the two products and pure MET powder were performed using a DSC-60 Plus instrument (Shimadzu, Kyoto, Japan). For each product, a precise amount of 3–5 mg powder was weighed and loaded into sample pans for thermal analysis. The scanning temperature for each sample was performed between 25 and 350 °C at a rate of 10 °C per min, while a constant flow of nitrogen at 100 mL/min was maintained in a controlled environment. LabSolutions TA software was used to process and analyze the obtained results. The experiment was performed on six samples of each product (n = 6) to ensure the statistical validity of the results.
