A deep understanding of the thermal properties of 2D materials is crucial to their implementation in electronic and optoelectronic devices. In this study, we investigated the macroscopic in-plane thermal conductivity (κ) and thermal interface conductance (g) of large-area (mm) thin film made from MoS nanoflakes via liquid exfoliation and deposited on Si/SiO substrate. We found κ and g to be 1.5 W/mK and 0.23 MW/mK, respectively. These values are much lower than those of single flakes. This difference shows the effects of interconnections between individual flakes on macroscopic thin film parameters. The properties of a Gaussian laser beam and statistical optothermal Raman mapping were used to obtain sample parameters and significantly improve measurement accuracy. This work demonstrates how to address crucial stability issues in light-sensitive materials and can be used to understand heat management in MoS and other 2D flake-based thin films.

The effects of dairy sterilization techniques (65 °C/30 min, 72 °C/15 s, 85 °C/15 s, 100 °C/5 min, and 121 °C/5 s) on the epigallocatechin-3-gallate-casein (EGCG-CS) complexes were investigated through the structural and functional characteristics in this work. Fourier transform infrared spectroscopy (FT-IR) detection showed the redshirting of the absorption peak suggested structural changes in the amide I area. Field emission scanning electron microscopy (FESEM) and viscosity measurements proved that treatments above 85 °C broke non-covalent bonds, leading to instability and low viscosity of EGCG-CS.

In this study, ultrasound-assisted glycated ovalbumin (G-UOVA) based on natural deep eutectic solvents (NADES) was prepared using response surface optimization. The binding affinity of (-)-gallocatechin gallate (GCG) to native OVA (NOVA), ultrasound treated OVA (UOVA), glycated OVA (GOVA), and G-UOVA followed G-UOVA > GOVA > UOVA > NOVA. The effects of various modifications and GCG binding on the secondary structure, particle size, and thermal stability of NOVA were investigated.

Electrodialysis (ED) has already been applied to recover nickel in galvanizing processes, allowing nickel recovery and the production of a treated effluent with demineralized water quality. However, the growth in ED use is still limited by the production and commercialization of ion-selective membranes, currently limited to a few large companies. Therefore, this paper presents the development of homogeneous cationic and anionic membranes made from poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) for ED use.
