Expanding the Frontiers of nail product evaluation: Novel application of differential scanning calorimetry (DSC) for assessing crosslinking density and predicting nail brittleness and flexibility.

While modern industry advancements have expanded nail beautification options, scientific literature primarily focuses on nail biology and medicine, with limited attention on cosmetic treatments. This study aimed to investigate human nail denaturation properties, including gender impact, blending nails to enlarge the sample pool, nail sensitization through bleaching, and active effectiveness testing. The objective was to understand the DSC and bending fatigue relationship, and define the consumer relevance of the DSC test. Nail clippings were collected from adult female and male volunteers. The wet DSC was employed to validate sample preparation, explore the effects of gender, and assess the potential of using blended nails for claims substantiation testing. Nails were sensitized through bleaching using hydrogen peroxide. The effects were confirmed through DSC and nail flexure tests. Furthermore, the ability of actives to address concerns related to nail softness and brittleness was assessed using these techniques. The results confirmed the viability of equilibrating nails in water for up to 14 h as a standardized testing method. The denaturation temperature results were independent of gender and suitable for claims substantiation testing. Blending nails from different sources did not yield significant variations in denaturation properties. A preliminary study suggested that cadaver nails should be used with caution because they exhibited differences in denaturation temperature, influenced by the sampling location. Bending fatigue tests highlighted the significance of humidity, with higher humidity conditions (80%) enhancing nail flexibility and providing better resolution for claims substantiation. Sensitizing the nails with hydrogen peroxide induced alterations in both DSC and bending fatigue results. Proof-of-principle studies demonstrated an elevation in denaturation temperature and a decrease in the number of cycles to break, indicating a nail-hardening effect when formaldehyde was applied. The use of a nail softener led to an enhancement in nail fatigue resistance due to a notable reduction in nail crosslinking density. The measurement of crosslinking density proved to be a sensitive tool for assessing the effects of cosmetic treatments on nails, particularly in predicting outcomes related to nail brittleness and flexibility.

Regression analysis for the determination of microplastics in sediments using differential scanning calorimetry.

This research addresses the growing need for fast and cost-efficient methods for microplastic (MP) analysis. We present a thermo-analytical method that enables the identification and quantification of different polymer types in sediment and sand composite samples based on their phase transition behavior. Differential scanning calorimetry (DSC) was performed, and the results were evaluated by using different regression models. The melting and crystallization enthalpies or the change in heat capacity at the glass transition point were measured as regression analysis data. Ten milligrams of sea sand was spiked with 0.05 to 1.5mg of microplastic particles (size: 100 to 200µm) of the semi-crystalline polymers LD-PE, HD-PE, PP, PA6, and PET, and the amorphous polymers PS and PVC. The results showed that a two-factorial regression enabled the unambiguous identification and robust quantification of different polymer types. The limits of quantification were 0.13 to 0.33mg and 0.40 to 1.84mg per measurement for semi-crystalline and amorphous polymers, respectively. Moreover, DSC is robust with regard to natural organic matrices and allows the fast and non-destructive analysis of microplastic within the analytical limits. Hence, DSC could expand the range of analytical methods for microplastics and compete with perturbation-prone chemical analyses such as thermal extraction-desorption gas chromatography-mass spectrometry or spectroscopic methods. Further work should focus on potential changes in phase transition behavior in more complex matrices and the application of DSC for MP analysis in environmental samples.

Heat–Cool: A Simpler Differential Scanning Calorimetry Approach for Measuring the Specific Heat Capacity of Liquid Materials

Specific heat capacity at constant pressure cp (J K−1 g−1) is an important thermodynamic property that helps material scientists better understand molecular structure and physical properties. Engineers control temperature (through heat transfer) in physical systems. Differential Scanning Calorimetry (DSC) is an analytical technique that has been used for over fifty years to measure heat capacities with milligram size samples. For existing procedures, such as ASTM E1269−11 (2018), the accuracy of molar heat capacity measurements is typically ±2–5% relative to the literature values, even after calibration for both heat flow and heat capacity. A comparison of different DSC technologies is beyond the scope of this paper, but the causes of these deviations are common to all DSC instruments, although the magnitude of the deviation (observed and accepted) varies with instrument design. This paper presents a new approach (Heat–Cool) for measuring more accurate and reproducible specific heat capacities of materials. In addition to better performance, the proposed method is faster and typically requires no additional calibration beyond the routine calibration of temperature and heat flow, with melting point standards common to all applications of DSC. Accuracy, as used throughout this paper, means deviation from the literature. The estimated standard deviation of repeated measurements of the cp values obtained with the Heat–Cool technique typically falls in the ±1–2% range.

State of the art: Multiscale evaluation of bitumen ageing behaviour

• Multiscale evaluations of the effect of ageing on bitumen were reviewed. • The bulk performance of bitumen is closely related to the micro even nano properties. • Chemical parameters can be used to characterise the rheological performance of bitumen. • Inter-hierarchy scale should be combined within the research of bitumen ageing. Ageing is a common phenomenon that seriously affects the performance and service life of asphalt pavements. In this paper, multiscale evaluations of bitumen ageing behaviour were reviewed to better understand the bitumen ageing mechanism and thereby contribute to future anti-ageing and binder rejuvenation work in this area. The paper initially looks at conventional as well as bespoke ageing methods before concentrating on bitumen ageing evaluation at different scales ranging from macro, meso , micro to nano scale. This is done by introducing the application of differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) in thermal indices; thin-layer chromatography-flame ionization detector (TLC-FID), gel permeation chromatography (GPC) and Fourier infrared spectrometer (FTIR) in components and functional groups; atomic force microscopy (AFM), optical spectroscopy and fluorescence spectroscopy (FM) in microstructural analysis; and, finally, nuclear magnetic resonance (NMR), time-of-flight secondary ion mass spectrometry (TOF-SIMS) and molecular dynamic simulations at the nanoscale. This review paper highlights the intricate correlations between the different hierarchical scales of bitumen ageing and the importance of a multiscale approach to provide a more comprehensive study and understanding of the ageing of bitumen.

Essence of Thermal Analysis to Assess Biodiesel Combustion Performance

The combustion phenomena are always complex in nature due to the involvement of complex series and parallel reactions. There are various methods that are involved in analyzing combustion phenomena. Viscosity is the first and foremost factor that acts as the DNA of fuel. By evaluating the viscosity, it is possible initially to understand the combustion phenomena. Thermophysical and transport properties are helpful during the intensification of the combustion process. Combustion experiments are economically infeasible and time-consuming processes. Combustion simulations demand excellent computational facilities with detailed knowledge of chemical kinetics. So far, the majority of researchers have focused on analyzing coal combustion phenomena, whereas less work has been carried out on liquid fuels, especially biodiesel combustion analysis. Traditional engine testing provides only performance parameters, and it fails to have oversight of the thermodynamic aspects. The application of thermal analysis methods in combustion research is useful in the design, modeling, and operation of the systems. Such investigations are carried out extensively in the combustor, engine, and process industries. The use of differential scanning calorimetry (DSC) and thermogravimetry (TG) to assess the properties of biofuels has been attracting researchers in recent years. The main objective of this paper is to discuss the application of TGA and DSC to analyze heat flow, enthalpy, thermal stability, and combustion indexes. Moreover, this paper reviews some of the other aspects of the kinetics of combustion, transport properties’ evaluation, and combustion simulations for biodiesels and their blends. TG curves indicate two phases of decomposition for diesel and three phases for biofuel. The B-20 blend’s (20% biodiesel and 80% diesel) performance was found to be similar to that of diesel with the combustion index and intensity of combustion nearly comparable with diesel. It is thermally more stable with a high offset temperature, confirming a longer combustion duration. A case study reported in this work showed diesel and B20 JOME degradation start from 40 °C, whereas jatropha oil methyl ester (JOME) degradation starts from 140 °C. JOME presents more decomposition steps with high decomposition temperatures, indicative of more stable compound formation due to the oxidation process. The peak temperature of combustion for diesel, JOME, and B20 JOME are 250.4 °C, 292.1 °C, and 266.5 °C, respectively. The ignition index for the B-20 blend is 73.73% more than that of diesel. The combustion index for the B20 blend is 37.81% higher than diesel. The B20 blend exhibits high enthalpy, better thermal stability, and a reduced peak temperature of combustion with an improved combustion index and intensity of combustion nearly comparable to diesel.

Calorimetric Markers for Detection and Monitoring of Multiple Myeloma.

Simple SummaryThis review highlights the potential of differential scanning calorimetry for multiple myeloma diagnosis and monitoring of the treatment outcome. The thermodynamic signatures of blood sera from patients with multiple myeloma are strongly dependent on the concentration and isotype of the secreted monoclonal immunoglobulins. Mathematical methods developed to analyze the biocalorimetry data and distinguish “diseased” from “healthy” thermogram to stratify plasma calorimetric profiles and determine specific interrelations between calorimetric and biochemical/clinical data are discussed.This review summarizes data obtained thus far on the application of differential scanning calorimetry (DSC) for the analysis of blood sera from patients diagnosed with multiple myeloma (MM) with the secretion of the most common isotypes of monoclonal proteins (M-proteins), free light chains (FLC) and non-secretory MM, as well as Waldenström macroglobulinemia and the premalignant state monoclonal gammopathy of undetermined significance. The heterogeneous nature of MM is reflected in the thermal stability profiles of the blood serum proteome of MM patients found to depend on both the level and the isotype of the secreted M-proteins or FLC. Common calorimetric markers feature the vast majority of the different myeloma types, i.e., stabilization of the major serum proteins and decrease in the albumin/globulin heat capacity ratio. A unique calorimetric fingerprint of FLC molecules forming amorphous aggregates is the low-temperature transition centered at 57 °C for a calorimetric set of FLC MM and at 46–47 °C for a single FLC MM case for which larger aggregates were formed. The calorimetric assay proved particularly advantageous for non-secretory MM and is thus a suitable tool for monitoring such patients during treatment courses. Thus, DSC provides a promising blood-based approach as a complementary tool for MM detection and monitoring.

Differential scanning calorimetry for authentication of edible fats and oils - What can we learn from the past to face the current challenges?

Fats and oils authentication has become an important issue recently, due to the growing interest in consumption of cold-pressed oils. Therefore, it is becoming more and more difficult to maintain official control over the growing assortment of new cold-pressed oils. Authenticity of plant oils is also an important issue for religious or cultural reasons.This review article focuses on the application of differential scanning calorimetry (DSC) in the field of assessing authenticity of various fats and oils (e.g. olive oil, palm oil, confectionery fats, butter). Extra virgin olive oil (EVOO) is the most comprehensively tested oil by means of the DSC technique in terms of the authenticity of origin as well as the adulteration with foreign oils. In most of the studies on DSC applicability for authentication, crystallization and melting curves were analyzed by the conventional DSC, although other modified DSC methods were also applied, such as isothermal freezing, modulated temperature DSC (MT-DSC) and fast DSC. However, the most promising are the melting profiles, which, due to the complexity of transitions, need advanced chemometric tools as well as tools for peaks deconvolution. The future prospect of using DSC in the authenticity assessment lies also in the use of DSC techniques along with other complementary chromatographic or spectroscopic techniques.

Deep eutectic solvents based on L-Arginine and glutamic acid as green catalysts and conductive agents for epoxy resins

Many engineered epoxy products in the recent years require sustainable materials to be contributive in the coming decades. The efficiency of [DES]Arg/Eg and [DES]Glu/Eg deep eutectic solvents (DESs) on the curing reaction of bisphenol A diglicydyl ether (DGEBA) with the application of differential scanning calorimetry (DSC) at temperatures 313–333 K is assessed. The both DESs studied here can act as the catalyst of epoxy-amine reaction, hardener and conducting agents in a simultaneous manner. Moreover, it reveals different reaction kinetics which strongly depend on the type of hydrogen bonding acceptor of the mixture. It is observed that there exist many fundamental differences between the progress of isothermal curing reaction in the presence of [DES]Arg/Eg and [DES]Glu/Eg considering the conductive ionic liquids and non-conductive conventional hardeners. The [DES]Glu/Eg at lower concentrations exhibits different catalytic behavior in the initial stages of the reaction, in a sense that the reaction progresses at higher rates up to 5 min and hampered afterward. In contrast, [DES]Arg/Eg act as a high-efficient catalyst in a sense that it allows the curing reaction approaches the completion level within 30 min which is comparable to previously reported conducting dopants. From kinetic results it is deduced that the mechanism of curing reaction follows the first-order kinetic in the presence of [DES]Arg/Eg and [DES]Glu/Eg and reaction occurring in the presence of [DES]Glu/Eg is characterized by higher activation energy compared to [DES]Arg/Eg. To analyze the efficiency of DESs as a catalyst for the epoxy-amine reaction, a computational study is run on a simplified model reaction catalyzed by [DES]Glu/Eg revealing a significant decrease in activation energy of the catalyzed reaction.

The Application of Differential Scanning Calorimetry to Investigate Precipitation Behavior in Nickel-Base Superalloys Under Continuous Cooling and Heating Conditions

A suite of experimental tools and fast-acting, numerical-simulation techniques was used to quantify the precipitation behavior of three nickel-base superalloys: IN-100, LSHR, and 718. Experimental methods comprised differential scanning calorimetry (DSC) to establish the specific heat as a function of temperature and selected direct-resistance heating trials (using a Gleeble® machine) to obtain samples for microstructural analysis. For the DSC experiments, each alloy was cooled at a prescribed constant rate (between 5 and 20 K/min) after an initial soak/equilibration in the high-temperature, single-phase (supersolvus) temperature regime. On-heating DSC trials beginning at ambient temperature were also performed on alloy 718 in three different starting conditions: super-δ-solvus solution treated and water quenched (denoted as ST), solution treated and aged (STA), and solution treated and overaged (STOA). DSC results, revealing the thermal signatures associated with the kinetics of precipitation of γ′ (IN-100, LSHR) or γ′ and γ″ (718), were interpreted using a previously-developed fast-acting routine that treats concurrent nucleation, growth, coarsening, and dissolution. For these simulations, special attention was paid to various thermo-kinetic input parameters including equilibrium solvus-approach curves, bulk free energies of transformation, matrix-precipitate interface energies, and effective diffusivities. For the γ-γ′ superalloys (IN-100 and LSHR), estimates of precipitate volume fraction as a function of temperature from the specific-heat data revealed semi-quantitative agreement with simulation predictions. For the γ-γ′-γ″ superalloy (718), simulation predictions of precipitate volume fractions were converted to specific heat as a function of temperature and showed semi-quantitative agreement with the direct measurements.

Investigation of polyelectrolyte multilayers deposited on corona charged composite polylactic acid / poly(ε-caprolactone) substrates

In the present study chitosan and casein polyelectrolyte multilayers (PEMs) deposited on composite polylactic acid (PDLA) / poly(ε-caprolactone) (PEC) substrates were investigated. The substrate’s morphology was investigated using polarized light microscopy and their degree of crystallization was studied by the application of differential scanning calorimetry. The substrates obtained were charged in a corona discharge system, consisting of a corona electrode (needle), a grounded plate electrode, and a metal grid placed between them. Positive or negative 5 kV voltage was applied to the corona electrode. 1 kV voltage of the same polarity as that of the corona electrode was applied to the grid. The dependences of the normalized surface potentials on the storage times of positively and negatively charged substrates were studied. Layer-by-layer (LbL) technique was used for multilayer deposition on the substrates. PEMs with different number of layers (4 or 8) were obtained. A model drug Benzydamine hydrochloride was loaded in the casein layers in order to evaluate the effect of the kind of substrate on the drug immobilization and release. A study of the drug release kinetics in saline buffer was carried out and the amount of the released drug was calculated spectrophotometrically. It was shown that the experimental results fit to the Peppas model with a very good level of correlation and the model parameters differ depending on the used substrate.

Applications of Differential Scanning Calorimetry (DSC) in Oils and Fats Research. A Review

This review is designed to be a comprehensive review in a new way to help you to understand the principle and theory of Thermal Analysis with special emphasis on Differential Scanning Calorimetry (DSC) as a new fast-growing and important technique used for authentication, characterization and detecting adulterations of oils and fats. DSC is a powerful instrument that measures the energy absorbed or released as a function of time or a controlled temperature profile. The sensor of the DSC is the heat flux plate which is designed to give superior performance and rugged reliability. The heat flux plate is capable of measuring small energy changes over the entire temperature range. Examples of measurements with DSC are Oxidative Stability, Melting Enthalpy, Glass Transition, Heat of Crystallization, Purity Determination and Heat Capacity. DSC can be used as a rapid method for assessment of oxidative stability, prediction of shelf life and evaluation of the quality of edible oils during refining. DSC holds a potential to be used as the reliable and reproducible technique for the detection of adulteration of animal body fat added in ghee individually and in combination of vegetable oil. DSC method is faster, require less sample size and no chemicals or solvents compared to other conventional, modern oxidative stability methods and conventional shelf life estimation.

Characterisation of bovine and buffalo anhydrous milk fat fractions along with infant formulas fat: Application of differential scanning calorimetry, Fourier transform infrared spectroscopy, and colour attributes

In this study, bovine and buffalo milk-derived ghee were fractionated using dry and solvent fractionation methods. Three different fractions including olein, stearin 1, and acetone washed-stearin (stearin 2) were obtained. The fatty acids composition, thermal profiles, and colour attributes of milk fat fractions were analysed along with infant formulas’ fat. Furthermore, Fourier transform infrared spectroscopy was applied in the wavenumber region of 4000–500 cm−1 to discriminate the different fractions. The results showed significant differences in fatty acids composition among the different types of fat, and stearin 2 fractions presented the highest saturated fatty acids content (90.38 and 83.30% for bovine stearin 2 and buffalo stearin 2, respectively). The different fractions of milk fat in addition to infant formulas fat demonstrated wide variations in their thermal behavior. The chroma and yellowness index values of bovine ghee, olein, and stearin 1 were significantly higher than those of the other fractions. The potential application of milk fat fractions as human milk fat substitutes needs further investigation.

Standardization of vitrification treatments for safe cryo-conservation of banana (Musa acuminata Colla) cultivars using differential scanning calorimetry

Cryo-conservation is the most promising approach and reliable method for long term conservation of banana and plantain genetic resources. Prior to the development of a safe cryo-conservation procedure for highly hydrated tissues of any vegetatively propagated crop species such as banana, suitable vitrification treatments involving loading solution in combination with Plant Vitrification Solution 2 (PVS2) solution have to be standardized. In the present study, Differential Scanning Calorimetry (DSC) technique was attempted to identify the best vitrification treatment using shoot apices as storage explants in two banana cultivars namely Grand Naine and Red banana. The results showed that DSC thermogram curves detected the formation of ice nucleation at a temperature of -18.67°C for Grand Naine and -19.16°C for Red banana in the control shoot apices. Among the sixteen vitrification treatment combinations tested, the treatments, LP6, LP7, LP10, LP11, LP14 and LP15 were judged as best treatments for cryo-conservation of both banana cultivars as revealed by the formation of glass transition events in the vitrified shoot apices. This information obtained through DSC experiments would further provide scope for designing safe cryo-conservation system for banana. This is the first report to demonstrate the application of DSC to optimize the vitrification treatments that would be adopted for developing cryo-conservation protocol for Musa germplasm.

Application of Differential Scanning Calorimetry (DSC) and Modulated Differential Scanning Calorimetry (MDSC) in Food and Drug Industries.

Phase transition issues in the field of foods and drugs have significantly influenced these industries and consequently attracted the attention of scientists and engineers. The study of thermodynamic parameters such as the glass transition temperature (Tg), melting temperature (Tm), crystallization temperature (Tc), enthalpy (H), and heat capacity (Cp) may provide important information that can be used in the development of new products and improvement of those already in the market. The techniques most commonly employed for characterizing phase transitions are thermogravimetric analysis (TGA), dynamic mechanical analysis (DMA), thermomechanical analysis (TMA), and differential scanning calorimetry (DSC). Among these techniques, DSC is preferred because it allows the detection of transitions in a wide range of temperatures (−90 to 550 °C) and ease in the quantitative and qualitative analysis of the transitions. However, the standard DSC still presents some limitations that may reduce the accuracy and precision of measurements. The modulated differential scanning calorimetry (MDSC) has overcome some of these issues by employing sinusoidally modulated heating rates, which are used to determine the heat capacity. Another variant of the MDSC is the supercooling MDSC (SMDSC). SMDSC allows the detection of more complex thermal events such as solid–solid (Ts-s) transitions, liquid–liquid (Tl-l) transitions, and vitrification and devitrification temperatures (Tv and Tdv, respectively), which are typically found at the supercooling temperatures (Tco). The main advantage of MDSC relies on the accurate detection of complex transitions and the possibility of distinguishing reversible events (dependent on the heat capacity) from non-reversible events (dependent on kinetics).

Термический анализ в исследовании качества шоколада и кондитерских изделий

High and unstable prices on such cocoa products as cocoa butter have triggered a search for substitutes. Thus, it is necessary to develop identification methods for chocolate authenticity, since chocolate is one of the most popular confectionery products. The present research employed the methods of thermal and thermomechanical analysis to study samples of chocolate produced in the countries of the Eurasian Economic Community (the Russian Federation, the Republic of Kazakhstan, and the Republic of Belarus) and chocolate bars with cocoa butter substitutes. An analysis of the sucrose – cocoa butter (CB) system revealed that samples with CB = 10–30%, 60%, and 90% demonstrated a single polymorphic modification of glycerides CB α-form with a melting point of 21–23°C. The samples with CB = 0%, 50%, 70%, and 80% showed a more heat-resistant modification (β’-modification) with a maximum melting point of 27.0–27.5°C. In addition, the melting peaks of glycerides were found not constant, which may indicate a eutectic effect in the sucrose – CB system. The samples of chocolate produced in the Russian Federation and the Republic of Kazakhstan passed the tempering stage and demonstrated the most heat-resistant β-modification of CB. However, the samples differed in the melting temperature: T max = 33.9°C for the Russian chocolate and T = 34.8°C for 
 the samples from Kazakhstan (the Rakhat brand). The samples from Belarus did not pass the tempering and were found to contain a thermodynamically unstable CB α-phase (the Kommunarka factory). The samples produced by the Spartak factory (Gomel, the republic of Belarus) contained an additional CB β’-phase. The differential scanning calorimetry (DSC) curves for chocolate bars with CB substitutes differed from the DSC curves for cocoa butter and chocolate samples. The fact can be used for identification. The DSC method can be used to identify the individual characteristics of the producer of chocolate and its analogues since the parameters of the melting curve of the fat phase and the shape of the curve are individual. The thermomagnetic analysis (TMA) method complemented the identification by determining the mass fraction of the liquid phase. Joint application of DSC and TMA methods allowed the authors to evaluate the quality of chocolate, its formulation, as well as to reveal the presence of cocoa products substitutes in the samples as compared to the reference sample.

Post-harvest assessment of wheat and barley kernel infections with fungi of the genus Fusarium using thermal analysis

The aim of this study was to evaluate the applicability of differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) for discriminating wheat and barley kernels naturally infected with fungi of the genus Fusarium from healthy kernels. Differences in selected thermal parameters were observed between infected and healthy kernels. In infected wheat kernels, the 2nd endothermic peak occurred at 58.6–62.3 °C, the 3rd endothermic peak at 270.1–279.7 °C; the area under the DSC curve was determined at 1842–2246 J g−1, and mass loss at 76.26–80.39%. In healthy wheat kernels, the above parameters were determined at 77.0–78.9 °C, 292.6–311.0 °C, 1180–1432 J g−1, and 71.10–74.92%, respectively. In infected barley kernels, the 2nd endothermic peak occurred at 51.6–56.4 °C, the 3rd endothermic peak at 286.1–290.1 °C; the area under the DSC curve was determined at 1752–1998 J g−1, and mass loss at 78.65–81.22%. In healthy barley kernels, the investigated parameters were determined at 69.1–74.3 °C, 310.0–324.9 °C, 1187–1249 J g−1, and 72.18–74.09%, respectively.
