Summary: This study provides data on the IR spectra of kaolinite at different moisture levels and explores the interaction between liquid water and the sorbing basal surfaces of kaolinite. The results suggest that the adsorption effect is weaker than the solvation effect, and it decreases with increasing salinity. The study also observes an increase in peak intensities during the drying process. These findings are valuable for testing theoretical models and computer simulations of moist minerals and salt adsorption mechanisms.

Summary: By using advanced machine learning techniques, researchers have found that dissolving salt in water does not lead to drastic changes in the structure of water. Contrary to previous beliefs about the pressure effect, the study shows that the ions in salt water only disrupt the hydrogen bond network within the first solvation shells, without significantly altering the oxygen radial-distribution function. This finding challenges the widely accepted pressure-like effect in Hofmeister series ionic solutions.

Summary: The Raman spectra of (D2O + H2O) - NaCl solutions at different ratios were analyzed. Water structures in the solutions were discussed based on solute-correlated (SC) OD/OH stretch bands. The results showed that isotopic substitution had an effect on the relative intensity of high-wavenumber modes and led to structural transitions. The hydration shell mainly consisted of single donor (SD) and single hydrogen-bond water (SHW) configurations. The increase of isotopic substitution ratio strengthened the interaction between D2O and Cl- in the hydration shell.

Summary: The study found that substituting sodium bicarbonate for sodium chloride led to an increase in pH and the absolute values of Zeta potential, active sulfhydryl, and surface hydrophobicity of myofibrillar protein solution, while decreasing turbidity, particle size, and Ca2+-ATPase activity. Additionally, Mg(2+)ATPase activity was not significantly affected by sodium bicarbonate, implying that it does not impact actin, but may induce protein denaturation.

Summary: This study investigates the response of decapod crustaceans to salinity changes through osmoregulatory and cell volume regulatory mechanisms. Four different species exhibited varied hemolymph osmolality and ion concentrations when exposed to different salinity levels, with a higher correlation between hemolymph and muscle ions observed in species with lower osmoregulatory strength. The findings highlight the importance of understanding the interplay between extracellular and tissue ionic pools in euryhaline species.

Summary: Three types of carbonate building stones from Turkey were tested for their physical and mechanical properties after freeze-thaw cycles with salt solutions. Material characterization, including chemical and mineralogical-petrographic tests, pore size distribution, and physico-mechanical tests, was performed. The results showed that water absorption, uniaxial compressive strength, and ultrasonic wave measurement values of all samples increased after multiple freeze-thaw cycles. However, the water absorption of silver travertine and Burdur limestone decreased due to the presence of small pores. The ultrasonic pulse velocity (UPV) values of travertine samples decreased gradually with more freeze-thaw cycles, and the uniaxial compressive strength (UCS) values of all samples decreased in all solutions.

Summary: Requeson cheese, made from whey proteins, is an economical option in Latin American countries. The study found that the addition of salts and packaging methods influenced the cheese's antioxidant and ACE inhibitory activities. To create a cheese with ACE inhibitory capacity, it is recommended to avoid adding salt or add 1% salt (NaCl) and vacuum pack it. For a cheese with antioxidant activity, adding 1.5% salt (NaCl or NaCl/KCl) and packaging it in a polyethylene bag or vacuum is recommended.

Summary: This study aims to investigate the influence of solvate shells interaction on the profiles of infrared spectra of sodium chloride solutions. Experimental measurements of infrared spectra were conducted on distilled water and sodium chloride solutions at limit and half-limit concentrations. Theoretical calculations using the DFT approach with the XLYP exchange-correlation potential were employed to compute the infrared spectra profiles for clusters containing 9 water molecules and one NaCl molecule. The results showed that the infrared spectrum is mainly influenced by the interaction of Na+ and Cl- solvation shells, each consisting of 4 water molecules, with the 9th water molecule providing bonding between the solvated ions.

Summary: A novel polymer conjugate has been developed to form anisotropic nanoassemblies independent of the crystalline nature of the hydrophobic block. Molecular dynamics simulations show that rigid hydrogen-bonding motifs contribute to the anisotropic alignment of block copolymers, and amorphous hydrophobic blocks containing these motifs can form nonspherical assemblies. Enhanced cell proliferation is observed in cell cultures containing anisotropic polymer assemblies with specific aspect ratios or lengths.

Summary: This study utilized frequency modulation atomic force microscopy (FM-AFM) to investigate the interfaces of blood-compatible polymers. It was found that the blood-compatible polymers exhibited thin repulsive layers composed of hydrated polymer chains in water-rich domains, while non-blood-compatible polymers did not show such layers. This discovery is significant for the design of blood-compatible materials.

Summary: A method for predicting hair breakage induced by change of molecular structure was proposed in this study. Infrared spectroscopy, coupled with multivariate curve resolution and two-dimensional correlation spectroscopy, was used to investigate the changes inside hair caused by cyclical extension. The experiments revealed that cyclical extension in bleached hair increased the signal of certain functional groups, leading to hair breakage. The agreement between the CH2 profile and the component profile suggested the translocation of lipids inside hair caused by cyclical extension. In contrast, untreated hair showed gradual increase in CH2 signal without breakage. By monitoring the functional groups in hair, this method has potential application in predicting hair breakage caused by cyclical extension.

Summary: This study prepared composite biomaterials of PHEMA/titanium-doped BGT for bone regeneration using the IW concept. The distribution and stability of the composites were confirmed, and the titanium doping improved the biomineralization properties. The IW level ranged from 10.4 wt% to 25.6 wt% with increasing titanium concentration. Cell viability tests showed that the growth rate increased with increasing titanium concentration, and an appropriate titanium concentration for cell adhesion was estimated to be 5%. Hydrated PHEMA gels with 5% BGT exhibited a high IW level of 19.3% and less hydrophilic wettability.

Summary: The stealth effect is crucial for enhancing the capabilities of nanomaterials in drug delivery applications. Through analyzing the efficiency and factors involved, we propose an integrated perspective on engineering stealth nanomaterials. The analysis reveals a common pharmacokinetics behavior, known as the pseudo-stealth effect, which leads to a rapid drop in blood concentration despite a relatively long b-phase. We suggest that a holistic approach, considering surface structure and geometry, is essential for improving the stealth effect.

Summary: Ring-opening metathesis polymerisation (ROMP) has become a popular method to synthesize complex functional polymers, due to the high tolerance of metathesis catalysts towards functional groups. It has emerged as an indispensable approach for designing and synthesizing polymeric biomaterials, enabling precise control over polymer structure and introduction of complex polar functional groups inaccessible by conventional polymerization methods. In this review, examples of precision polymer synthesis with polar functional groups are presented, along with their utilization as soft biomaterials in biotechnology and biomedical fields. Specifically, ROMP of functionalized monocyclic alkenes and synthesis of biomaterials using functionalized norbornene are discussed.
