The thermal properties of potato starch, wheat gluten, and starch–gluten composite systems were investigated using a differential scanning calorimeter (TA Q200, TA Instruments, New Castle, USA). Samples (3 mg) were weighed into stainless steel pans, and 10 μl of distilled water was added before the pans were hermetically sealed. The pans were equilibrated at 4°C for 12 hr before heating from 25 to 100°C at a rate of 5°C/min by DSC. The onset temperature (T₀), peak temperature (Tp), peak width at half height (ΔT), and endothermic enthalpy (ΔH) were calculated automatically. A sealed empty pan was used as reference.

The thermal properties of the blends are determined
on a DSC instrument (TA Q200, USA) under a N₂ atmosphere.
The samples are heated to 180 °C at 10 °C/min and maintained
for 3 min before cooling to −70 °C at 10 °C/min.
The second heating scans are monitored between −70 to 180 °C

(T_cc), melting temperature (T_m), and crystallinity (X_c).
Such studies are targeted to investigating the influence of peroxide
on the crystallization behavior of the blends.
The crystallinity

melting enthalpy of PBS (ΔH_PBS)
occurring at ∼112 °C and the weight ratio of PBS (W_PBS), as illustrated in eq 1. where ΔH_m is the melting enthalpy of PBS, ΔH_m^° is the melting enthalpy assuming
100% crystalline
PBS (220 J/g here),^{42 (link)} and w_f is the weight fraction of PBS in the blend.
The
crystallinity of PLA (X_PLA) is
calculated based on the melting enthalpy (ΔH_PLA), the cold crystallization enthalpy of PLA (ΔH_cPLA), and the weight ratio of PLA (W_PLA), as illustrated in eq 2. where the ΔH_m^′ and ΔH_c are the melting enthalpies and cold crystallization
enthalpies of PLA, ΔH_m^° is the melting enthalpy assuming
100% crystalline PLA (93.7 J/g here),^{43 (link)} and w_f^′ is the weight fraction
of PLA in the blend.

The thermal properties of oleofoams and oleogels were assessed by differential scanning calorimetry (DSC) (TA Q200 instrument, New Castle, UK). Around 20 mg of the sample were placed into a hermetically sealed aluminium pan for testing. An empty aluminium pan was used as a reference. DSC runs were carried out from 10 °C to 80 °C. The samples were scanned at a constant rate of 2 °C.min⁻¹ applying a heating-cooling cycle (two heating steps, with one cooling step in between). An isotherm of 10 min was applied at 80 °C before cooling, and at 10 °C before heating. The transition temperatures, enthalpies of melting and crystallization were determined from the DSC curves using TA Instruments’ Universal Analysis Software, in triplicate for each sample.

TA Instruments
Q500 was employed as a thermal gravimetric analyzer (TGA) to study
the thermal degradation of synthesized polymers. Samples (5–10
mg) were placed in platinum pans and heated to 450 °C at 10 °C/min.
The temperature corresponding to 3% mass loss was considered as the
thermal degradation temperature and used as a guide for the maximum
temperature that could be employed in further thermal processing and
analysis steps. A differential scanning calorimeter (DSC) TA Q200
was then used to measure transition glass transition temperatures
(T_g) and melting temperatures (T_m) of the polymers. Samples (3–5 mg, n = 3) were placed in t-zero aluminum pans
and equilibrated at −40 °C, heated to 150 °C at 10
°C/min kept isothermally for 2 min, cooled to 50 °C at 5
°C/min, kept isothermally for 20 min, cooled to −40 °C,
kept isothermally for 2 min, and finally reheated to 150 °C at
10 °C/min. The midpoint of the first endothermic inflection above
0 °C and the minimum of the melting peak in the second heating
cycle were recorded as the T_g and T_m of the hard segment, respectively.^{35 (link),36 (link)}

Characterizing Drug-Polymer Interactions in PSIs

To assess the physical state of DTG and PLGA in PSIs, differential scanning calorimetry (DSC) analyses of pure drug (DTG), optimized placebo PSIs, and optimized DTG PSIs were carried out using a differential scanning calorimeter (TA Q200, USA). Prior to DSC analysis, decomposition temperature (T_d) of DTG was determined using a thermogravimetric analyzer (TGA, TA Q500, USA). Briefly, pure DTG was weighed (10 mg), sealed in an aluminum pan, and placed into a thermogravimetric analyzer. The DTG sample was heated from 0 to 600 °C at a ramp-up rate of 10 °C/min under inert nitrogen gas introduced at a flow rate of 20 mL/min.
For DSC analysis, samples (3–5 mg DTG, 5–10 mg DTG or placebo PSIs) were weighed, hermetically sealed in an aluminum pan and subsequently placed in a differential scanning calorimeter. For each measurement, samples were heated from 0 to 250 °C at a rate of 10 °C/min under nitrogen (20 mL/min flow rate). The DSC thermograms were used to determine the peak glass transition temperature (T_g) of PLGA, melting point (T_m) of DTG, and the physical state of DTG in PSIs (i.e. crystalline or amorphous).

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.
