X-ray diffraction (XRD) patterns were recorded on a multipurpose XRD system D8 Advance from Bruker with a Cu Kα radiation. Raman-shift spectra were measured on a JY HR800 tool with laser excitation of 488 nm. UV-Vis absorption spectra were obtained using a Shimadzu 2660 UV-Vis spectrophotometer, and PL spectra were measured with a Varian Cary Eclipse instrument. High-resolution transmission electron microscopy (HRTEM) images were taken on a FEI Tecnai F30 S-TWIN. Fluorescence lifetimes were measured using a Horiba FM-4P time-corrected single photon counting system. FTIR spectra were recorded with a Tensor-27 spectrometer. X-ray photoelectron spectroscopy (XPS) analysis was carried out on an ARL-9800 instrument with a monochromatic X-ray source Al Kα excitation (1486.6 eV). Binding energy calibration was based on the C 1s peak at 284.6 eV. TG curves were recorded with a Pyris-1-TGA system from Perkin-Elmer. Sample images were taken by a digital camera under illumination from a UV lamp.
Pyris 1 tga system
Manufactured by PerkinElmer
Sourced in United States
The Pyris 1 TGA system is a thermogravimetric analyzer that measures the change in the weight of a sample as a function of temperature or time under a controlled atmosphere. It provides quantitative information about physical and chemical changes that involve mass loss or gain.

Ten milligrams of starch were placed on a platinum pan and heated from room temperature to 800 °C using a Pyris 1 TGA system (PerkinElmer, Waltham, MA, USA) at a heating rate of 10 °C/min. Nitrogen was used as a purge gas at a flow rate of 20 mL/min. Change in sample weight against temperature was measured.

Physicochemical characterization was conducted by infrared spectroscopy, coupled to an attenuated total reflectance accessory (IR-ATR) in a Spectrum GX System (Perkin Elmer-DuraSamplIR II, USA), 16 scans were taken in a range of 650–4000 cm−1. Thermogravimetric analysis was performed in a PerkinElmer Pyris 1 TGA system, in a nitrogen atmosphere at 20.0 mL/min flowrate. A heating ramp from 30.00 °C to 600.00 °C at 10.00 °C/min was used.
Crystallinity of the scaffolds was tested by X-ray diffractometry in a BRUKER D8 ADVANCE ECO X-ray diffractometer. The degree of crystallinity was calculated using the ratio of the area under the peaks to the total area (AT) under the XRD pattern [48 (link),49 (link)], which is the sum of the crystalline diffraction peak area (Ac) and the amorphous diffraction component (Aa) of the pattern (AT = Ac + Aa).
Differential scanning calorimetry (DSC) tests were carried out in a TA Instruments DSC-2920 system. Between 6–8 mg of each sample were scanned at a rate of 10 °C/min, using a heating/cooling/heating program, from 30 to 230 °C. The first heating was used to erase the thermal history, and the thermal properties were obtained from the second heating.
The wettability of the fabricated scaffolds was evaluated by measuring the contact angle of a 20 µL drop of distilled water on each sample (n = 6).

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
