Summary: The electrocaloric heat production in BaTiO3-based multilayer ceramic capacitors with Y5V specification was measured directly using an adiabatic calorimeter setup. Applying an electric field of 30 MVm(-1) resulted in a heat release of 0.94 J g(-1) and an electrocaloric temperature change of 0.46 K, which is consistent with previous studies.

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: A complete microstructural characterization of the stoichiometric Ni2Cr alloy after different ageing times in which different degrees of order are attained has been carried out. The study used synchrotron radiation diffraction to monitor the order-disorder transformation and found that the onset temperature is higher than previous reports. In addition, fine carbide precipitation was observed, which may contribute to the strengthening of the alloy.

Summary: The study focused on designing nanostructured lipid carriers (NLC) containing tocopheryl acetate as liquid lipid and loaded with idebenone, showing potential synergistic effects with antioxidant drugs. Investigating different percentages of tocopheryl acetate and idebenone in NLC, it was found that while the stability of the carriers was maintained with low levels of idebenone, higher levels led to poor stability during long-term storage.

Summary: Robust determination of parameters governing the stability of amorphous drugs is crucial in modern pharmaceutics. The kinetic stability of these systems greatly impacts their practical applications. This study determined the critical cooling rates and kinetic parameters of cold crystallization for four slowly crystallizing sulfonamides. The Nakamura crystallization model demonstrated good prognostic ability by determining the stability time profile of drug systems prone to crystallization from non-isothermal thermokinetic data.

Summary: The study investigated the impact of nitrogen incorporation on the initial phase of growth of 4H-SiC crystals, detecting doping concentration and stress using KOH etching and Raman spectroscopy. It was found that the altered thermal expansion coefficient caused by nitrogen doping plays a major role in the types and density of defects present in the grown crystal. Additionally, while the mounting method led to increased stress in the initial seeding phase, the overall stress induced by inhomogeneous nitrogen doping is orders of magnitude higher.

Summary: Multiscale approaches play an important role in materials processing simulation, offering cost reduction and performance enhancement. By integrating physical-chemical simulations and trained black-box techniques through digital twin modules, the real processes in development and production can be effectively complemented. This paper proposes a general paradigm for industrially driven computational modeling of materials using a multiscale methodology, which is demonstrated through two processing examples.
