Fractional List Packing for Layered Graphs

Journal of Graph Theory, EarlyView.
ABSTRACT The fractional list packing number χ ℓ • ( G ) ${\chi }_{\ell }^{\bullet }(G)$ of a graph G $G$ is a graph invariant that has recently arisen from the study of disjoint list‐colourings. It measures how large the lists of a list‐assignment L : V ( G ) → 2 N $L:V(G)\to {2}^{{\mathbb{N}}}$ need to be to ensure the existence of a “perfectly ...

A Green Amphoteric Surfactant Derived From Rapeseed Oil for Enhanced Oil Recovery From Carbonate Acidic Oil Reservoirs

Journal of Surfactants and Detergents, EarlyView.
The Green Amphoteric Surfactant Derived From Rapeseed Oil for Enhanced Oil Recovery From Carbonate Acidic Oil Reservoirs. ABSTRACT Surfactants with both positive and negative functional groups (amphoteric or zwitterionic) are particularly advantageous in acidic oil reservoirs because they remain stable under harsh chemical conditions, tolerate acidic ...

FRET‐Based Investigation of the Dynamics of Peptide‐Folded Single Chain Nanoparticles Inside Cancer Cells

Macromolecular Rapid Communications, EarlyView.
Little is known about the cellular uptake of single chain nanoparticles that are cross‐linked with dynamic bonds. Using Förster resonance energy transfer and fluorescence lifetime imaging microscopy (FRET‐FLIM) the dynamic nature of the bonds is seen, in which the interaction between two peptides, disassemble quickly, relatively.

Sulfonium‐Based Antimicrobial Block Copolymers: Influence of Hydrophobicity on Biological Activity and Antibiotic Synergy

Macromolecular Rapid Communications, EarlyView.
Sulfonium‐based antimicrobial block copolymers combine an active cationic hydrophobic block with a neutral hydrophilic block to improve cytocompatibility. The hydrophobicity of the sulfonium‐based block controls the activity against S. aureus and E coli.

Arsonic Acid Functional Polymers Enable Stabilization of Iron Oxide Nanoparticles in Aqueous Solution

Macromolecular Rapid Communications, EarlyView.
Arsonic acid containing diblock copolymers are developed to incorporate arsonic acid moieties for surface anchoring to IONPs, along with water soluble PEG blocks to impart colloidal stability in aqueous environments. The resulting polymer‐coated IONPs are evaluated for stability in physiological media and cytocompatibility.
