DNA Condensation by Peptide-Conjugated PAMAM Dendrimers. Influence of Peptide Charge
(Peer reviewed; Journal article, 2023)Nucleic acid delivery to cells is an important therapeutic strategy that requires the transport of nucleic acids to intracellular compartments and their protection from enzymatic degradation. This can be achieved through ... -
Effect of Low-Molecular-Weight Alcohols on Emulsion Stabilization with Lignosulfonates
(Peer reviewed; Journal article, 2020)Lignosulfonates are biobased surfactants and specialty chemicals, which are described as water-soluble polyelectrolyte macromolecules that are generated during the sulfite pulping of lignocellulose biomass. Due to their ... -
Effect of Variations of Amine Content and Network Branching on Thermomechanical Properties of Epoxy Systems
(Journal article; Peer reviewed, 2024)In thermosetting epoxies, thermomechanical properties can be enhanced by conscious selection of curing agents. Full cross-linking leads to a maximum in the glass- transition temperature. However, the relation between the ... -
Effect of Water Interactions on Polyvinylamine at Different pHs for Membrane Gas Separation
(Journal article; Peer reviewed, 2017)In our previous work, it was shown that the separation performance of the fixed-site-carrier polyvinylamine (PVAm) composite membrane increases exponentially with increasing relative humidity content in the gas. Through ... -
Electronic Structure and Surface Chemistry of Hexagonal Boron Nitride on HOPG and Nickel Substrates
(Peer reviewed; Journal article, 2023)The effect of point defects and interactions with the substrate are shown by density functional theory calculations to be of significant importance for the structure and functional properties of hexagonal boron nitride ... -
