Summary: The study found that the size of microplastic particles affects the DSC signal, but through appropriate sample preparation, signals corresponding to microplastics of different sizes can be identified and quantified. Additionally, the application of DSC technique in the field of microplastics may provide estimates of the number of microplastic particles within a sample.

Summary: The contribution of thermodynamics of mixing to glass transition in polymer-modified asphalt binders was studied quantitatively using a differential scanning calorimeter with an epoxy system. The miscibility of the binders was determined by measuring the heat capacity (Cp) and glass transition temperature (Tg) based on entropic changes. The enthalpy of mixing was also examined to ensure complete crosslinking of the binders. The results showed that the positive deviations of Tg from the ideal mixing rule indicated the presence of repulsive forces between the asphalt and epoxy components.

Summary: In this study, the kinetics of non-isothermal cold-crystallization of quench-cooled carbamazepine (CBZ) were investigated using Differential Scanning Calorimetry under different heating rates. Various models were discussed for describing the mechanism of nucleation and growth, with the Matusita model being considered the most versatile one. It was found that the Matusita model properly described both surface and bulk crystallization mechanisms in different conditions of heating rates.

Summary: In this study, a concentrated cellulose nanofibril (CNF) suspension was prepared from bleached hardwood kraft pulp without pretreatment. The concentration process promoted the formation of pores in the CNFs, but these pores partially collapsed and shrunk during the re-dispersion and re-concentration process.

Summary: Differential scanning calorimetry is used to measure the thermodynamic properties of organogels, revealing broad endothermic peaks and their corresponding temperatures. The phase diagram explains why the molar melting enthalpies of low concentration samples are lower than expected, while the inflection points of thermograms provide a more accurate measurement of the gel melting temperature.

Summary: The study found that the gas conditions during the cooking process of cotton candy are crucial to its physical state and thermal stability. Cotton candy made in air was mainly crystalline with a small amorphous part, and easily degraded by aging. Meanwhile, cotton candy made in nitrogen gas exhibited a more glassy structure and had a different aging behavior compared to the one made in air.

Summary: Climate change is projected to significantly impact the habitat suitability for wild camels in the Kumtag Desert, with a predicted decrease of 43.81% in suitable habitat by 2050. Current nature reserves cover 57.86% of the suitable habitat, but 44.15% of it is expected to be vulnerable to future climate change.

Summary: This study investigated the non-isothermal cold crystallization behaviors of cork-polymer composites based on polylactic acid matrix. The results showed that cork powder residues act as a nucleating agent, accelerating the crystallization rate and reducing the half-time crystallization values. Additionally, the addition of cork was found to decrease the cold crystallization temperature of the PLA matrix.

Summary: In situ analysis of hydrothermal carbonization (HTC) and liquefaction (HTL) processes can be achieved using high-pressure differential scanning calorimetry (DSC). This study applies a newly developed DSC method to continuously assess the heat release profile of cellulose across the hydrothermal spectrum. The results reveal that both HTC and HTL are exothermic reactions, and a thermodynamic transition occurs at the transition from HTC to HTL. This novel DSC technique could reduce cost and time in evaluating potential feedstocks for HTC and HTL, expediting the commercialization of these thermochemical processes.
