The thermal behavior of the samples was analyzed using a Discovery DSC (TA Instruments, New Castle, DE, USA). All measurements were conducted under a constant 50 mL/min nitrogen gas flow. An amount of 2–5 mg of sample were weighed into aluminum pans and sealed with pierced lids. To measure the eutectic behavior of the samples, crystalline IND, crystalline PAR, and the PM of IND–PAR at different mixing ratios were heated up from 25 °C to 180 °C (at a rate of 10 °C/min to achieve better resolution). All measurements for the eutectic behavior investigation were conducted in triplicates. To investigate the thermal behavior of the CAMS or G-CAMS, samples were equilibrated at −20 °C for 1 min, then heated up to 180 °C (at a rate of 20 °C/min for better sensitivity). The DSC data was collected and analyzed using Trios software (version 5.1.1, TA Instruments, New Castle, DE, USA).
The water content of the samples was assessed by using thermogravimetric analysis (TGA) (Discovery TGA, TA Instruments, New Castle, DE, USA). Samples (around 10 mg) were heated from 25 °C to 300 °C at a rate of 20 °C/min. All measurements were conducted under a constant 50 mL/min nitrogen gas flow.

The experimental data were statistically analyzed by determining the average values and standard deviation, at the significance level of 95%, for each parameter evaluated. Statistical analysis (RStudio, Version 1.1.423) was performed by applying variance analysis, the one factor (ANOVA), and post-hoc comparisons (Tukey test). Experimental rheology data were fitted to the non-linear Carreau model, using the TA Instruments/TRIOS software.

Rheological Characterization of Viscoelastic Fluids

A Discovery Hybrid Rheometer 2 (DHR-2) (TA Instruments) with attached 40 mm parallel plate at gap height of 0.25 mm and 25°C was used for all experiments. Rotational shear rate sweeps were executed between 10−3-103 s−1 to determine the power law region. Power-law parameter n (flow behavior index) and K (flow consistency index) were calculated using TRIOS software (TA Instruments). Rotational time sweeps were executed at three different shear rates (s−1) in sequential order: 10−2 (60 s), 3000 (5s), 10−2 (120s) to determine shear recovery of solutions.[20 ] Time to 80% recovery was manually observed/calculated.[47 (link)] Oscillatory shear stress sweeps between 10−1-103 performed at 1 Hz and frequency sweeps between 100-102 performed at 10 Pa to further validate yield points and investigate dependence on frequency.

Rheological Characterization of Fluid Samples

Steady state shear flow measurements were carried out at increasing shear rates from 0.1 to 100 s−1 to measure the shear viscosities of samples.
Rheological data was analyzed using TRIOS software (TA Instruments, New Castle, DE, USA). Measurements were made in triplicate and average values are reported. To characterize the flow behavior of samples, the Newtonian or power law models were used. The flow behavior index (n, dimensionless) and consistency coefficient (K, Pa·sn) values were computed by fitting the rheological data to the power law model (Eq. (1)). τ=Kγ˙n Where, τ is the shear stress (Pa) and γ˙ is the shear rate (s−1). When n = 1, n < 1, and n > 1 the fluids are called Newtonian, pseudoplastic, and dilatant, respectively. The correlation coefficient (R) and standard error of estimates (SEE) were determined using Eqs. (2), (3)). R=(xx)(yy)(xx)2(yy)2 SEE=1(n2)[(yy)2[(xx)(yy)]2(xx)2] Where, x is the observed value, y is the estimated value, x and ȳ are the means of observed and estimated values, respectively, and n is the count of the total number of (x,y) pairs.

Differential Scanning Calorimetry Analysis of Starch Samples

Check if the same lab product or an alternative is used in the 5 most similar protocols
Differential Scanning Calorimetry (DSC) measurements were performed with a TA Instruments differential scanning calorimeter (model DSC 2500, New Castle, DE, USA) and the collected data were evaluated using TA instruments TRIOS software (V5.1.1.46572). Temperature and cell constant calibration of the instrument were carried out with Indium reference samples and calibration of heat capacity Cp was performed with sapphire crystal, provided by TA Instruments. Samples of model system suspension (~10 mg) were placed in hermetically sealed Tzero Aluminium pans and an identical empty pan was used as a reference.
All of the samples were heated from 25 to 100 °C with a heating rate of 5 °C/min. We subtracted baselines and divided the resulting heat flow by starch mass and heating rate, thus obtaining the change in heat capacity per gram of starch as a function of temperature. The observed heat effects were characterized by calculating the change in enthalpy as the area under experimental curve and transition temperature was determined as the curve peak position. Positive changes in heat capacity correspond to endothermic processes (endo up) and negative changes in heat capacity correspond to exothermic processes (exo down).

Differential scanning calorimetry (DSC) was performed using a TA Instruments Model Discovery DSC. Data was collected with TRIOS software and was analyzed using TA Instruments Universal Analysis software. A sample of the crystalline form was accurately weighed into an aluminum pan covered with a TZero hermetic pinhole lid. The sample was initially cooled to −20° C. after which the sample was heated using a linear heating ramp of 10° C./min from −20° C. to 250° C. A representative DSC thermogram of Form I is shown in FIG. 2.

Thermogravimetric analysis (TGA) measurements were performed using a TA Instruments Model Discovery TGA module equipped with high resolution capability. Data were collected using TA Instruments TRIOS software and analyzed using TA Instruments Universal Analysis software. A weighed sample was placed onto a platinum pan and scanned with a heating rate of 10° C. per minute from ambient temperature to 260° C. The balance and furnace chambers were purged with nitrogen flow during use. A representative TGA trace of Form I is shown in FIG. 3. A weight loss of about 3.4% between 27° C. and 100° C. was observed and corresponds to dehydration of a monohydrate form.

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.
