Ebook "Solid base catalysis (Springer series in Chemical physics, Volume 101)" is focused on the solid base. Because of the advantages over liquid bases, the use of solid base catalysts in organic synthesis is expanding. Solid bases are easier to dispose than liquid bases, separation and recovery of products, catalysts and solvents are less difficult, and they are non-corrosive. Furthermore, base-catalyzed reactions can be performed without using solvents and even in the gas phase, opening up more possibilities for discovering novel reaction systems.

Ebook "The physics of polymers: Concepts for understanding their structures and behavior" presents the elements of this important branch of materials science in the style of a series of lecture. The main focus lays on the concepts, rather than on experimental techniques and theoretical methods. Written for graduate students of physics, materials science and chemical engineering, as well as for researchers in academia and industry entering this field, the book introduces and discusses the basic phenomena that lead to the peculiar physical properties of polymeric systems.

In recent years, there has been growing evidence indicating a relationship between liquid–liquid phase separation (LLPS) and cancer development. However, to date, the clinical significance of LLPS in skin cutaneous melanoma (SKCM, hereafter referred to as melanoma) remains to be elucidated. In the current study, the impact of LLPS-related genes on melanoma prognosis has been explored.

This work describes an aid to three-dimensional (3D) reconstruction based on serial section technology for better characterizing non-transparent material microstructure and orientation. We found that two separate primary Al2Cu phase dendrites of directionally solidified Ale40%Cu alloy appeared in the twodimensional (2D) microstructure but were shown to be only one dendrite in the three-dimensional (3D) microstructure by using the assistive characterization method.

The magnetization, specific heat, and spin susceptibility of this system behave differently in these regions when the systems are subjected to an external magnetic field. For this reason, we want to deeply examine and analyze the thermodynamic behaviors of these mixed-magnetic clusters in light of the disorder Ising model.

In this study, antimicrobial nanofibers were produced with the mixtures of polyvinyl alcohol (PVA) and cyclotide-rich fractions by electrospinning method. After extraction, the first separation was carried out with C18 flash chromatography and then fractioned into five separate parts by reversed-phase high-pressure liquid chromatography (RP-HPLC). The molecular weights of cyclotides in each fraction were determined by quadrupole time-of-flight liquid chromatography-mass spectrometry (Q-TOF LC-MS).

This report presents the process of calculating, designing and manufacturing a box-type mixer-settler system used for rare earth solvent extraction process on laboratory scale. The basic design parameters of the mixer-settler were calculated from two-phase flow rates, the contacting phase ratio and mixing time in mixer, the phase separation time in settler, the densities, and the viscosities of two phases.

The effects of pH, ionic strength and polymer ratio in the complexation of chitosan (CHI) with different anionic polysaccharides, namely gum Arabic (GA), sodium alginate (ALG) and κ-carrageenan (CRG), were investigated. This was made using titration techniques, which allowed the determination of stoichiometry and binding constant of complexes.

In this work, simulations of xylan oligomers starting from random configurations at different levels of hydration are performed. The simulations show clear evidence of phase separation into water-rich and polymer-rich phases at higher hydration, in spite of standard indicators of equilibrium, such as density and energy, remaining constant.

In the present work, the structuring and stabilising potential of flaxseed gum (FG) in whey protein isolate (WPI) cryo-hydrogels was investigated. The FG presence (0.1–1% wt.) in the heat-treated WPI dispersions (10% wt.) induced strong segregative phase separation phenomena, which were associated with a depletion flocculation mechanism.
