Summary: It is now understood that the bonding in crystalline cellulose involves hydrogen bonding, dispersion forces, and electrostatic attraction influenced by cellulose conformation. The surface chains of cellulose microfibrils have a different conformation and form different hydrogen bonds depending on their interaction with water, other microfibrils, or non-cellulosic polymers. The specific details of these surface interactions, especially in the presence of other polymers, are still uncertain and require further research.

Summary: Hydrogen bonding and electrostatic interactions play crucial roles in the microstructure of soy hull polysaccharide and the stability of corresponding emulsions. The addition of urea and NaCl can disrupt these interactions, affecting the polysaccharide chain length and branching, as well as altering the adsorption kinetics at the oil/water interface. Furthermore, the emulsions with NaCl and urea showed changes in relaxation time and line width in 1H NMR analysis, indicating decreased interaction with oil molecules and potential impact on coalescence and flocculation.

Summary: The study investigates the semicrystalline colloidal gels composed of poly(methacrylamide-co-methacrylic acid) in water and reveals the influence of colloidal microstructure evolution on the gel's interfacial characteristics and underlying interactions. These interactions are crucial for the spatial and dynamic control of surface properties, and have implications for applications in biomedical devices, soft tissue design, soft robotics, and other engineered tribosystems.

Summary: Low-dimensional organic-inorganic metal halides (LOMHs) have gained significant attention for their tunable crystal structures and excellent photoelectric properties. This study systematically investigates the spatial and hydrogen bonding effects of organic cations on the structure and properties of LOMHs. Three LOMHs were synthesized and their blue-white emissions were attributed to free excitons (FEs) and self-trapped excitons (STEs). An ultraviolet-pumped light-emitting diode (LED) based on one LOMH showed high color rendering index (CRI) and correlated color temperature (CCT), demonstrating its potential in solid-state lighting.

Summary: Streaming potential and quartz crystal microbalance measurements were used to investigate the pH dependency of the adsorption of poly-L-lysine (PLL) and poly-L-arginine (PARG) on alpha-quartz surface, which was further supported by all-atom molecular dynamics simulations. The adsorption behavior was determined by the change in the number of peptide-surface ion pairs and the repulsive electrostatic interactions between the polypeptides. Low pH favored strong adsorption and stable monolayers, while high pH resulted in weakly bound but denser peptide films with limited stability. Electrostatic interactions, hydrogen bonding, and non-specific interactions played important roles in the adsorption process.

Summary: This study demonstrates that partial sulfation of Gellan gum (GG) can produce a cytocompatible temperature-responsive hydrogel. The resulting hydrogel shows an interesting thermoreversibility at 42°C and a drop in mechanical properties can be compensated by further calcium-mediated ionic crosslinking.

Summary: The study found that the co-occurrence of Haemophilus parainfluenzae and Streptococcus mitis in the oral cavity is density dependent and influenced by H2O2 production. H. parainfluenzae utilizes a more redundant, multifactorial response to H2O2, enhancing the fitness of S. mitis. The findings describe mechanistic interactions between these two abundant members of healthy supragingival plaque, contributing to their survival in vivo.

Summary: The study explores the noncovalent interactions of fluorinated compounds, the low charge capacity and polarizability of atomic fluorine, and how molecular surface electrostatic potentials affect the behavior of hydrocarbons and perfluorocarbons. The excellent expression of the aqueous solubilities of alkanes and perfluoroalkanes based on their intrinsic polarities, defined by their electrostatic potentials and molecular volumes, sheds light on the inertness and water-repelling abilities of linear perfluoroalkanes, known as the Teflon effect.
