Orientation Dependence of DNA Blunt-End Stacking Studied by Free-Energy Simulations.

DNA blunt ends can associate mediated by stacking interactions between the terminal base pairs that form blunt ends. The blunt end association plays a role in DNA repair and recombination processes and can also be of importance for the design of DNA-based nano-materials. Its function depends on the sequence and on the geometric arrangement that leads to stable interaction.

Effect of Chemical Grafting Parameters on the Manufacture of Functionalized PVOH Films Having Controlled Water Solubility.

This study investigated the chemical grafting of a single-layer poly(vinyl alcohol) (PVOH) film. The effect of the grafting parameters (grafting time, grafting temperature, and concentration of fatty acid chloride) on the hydrophobicity of the film surface and the film solubility were evaluated. The PVOH substrate film (cold-water soluble at 20°C) was manufactured by flat extrusion and had a thickness of 50 μm (±5 μm).

Effects of thermally induced denaturation on technological-functional properties of whey protein isolate-based films.

This study examined how and to what extent the degree of denaturation affected the technological-functional properties of whey protein isolate (WPI)-based coatings. It was observed that denaturation affected the material properties of WPI-coated films significantly. Surface energy decreased by approximately 20% compared with native coatings.
