Non‐Enzymatic Destruction of the Extracellular Matrix for Activatable Orthotopic Tumor Treatment and Enhanced Drug Penetration

Advanced Functional Materials, EarlyView.
Supramolecular biomimetic nanoaggregates (HFCu NAs), constructed with fluorinated histidine and copper ions via metal coordination and aromatic packing, exhibit enhanced reactive oxygen species （ROS）generation at tumor sites, which results in stepwise collapse of the extracellular matrix (ECM), affording tumor microenvironment responsive “turn‐on” 19F ...

Nanoscale Agglomeration Mechanisms of BF‐DPB:BPyMPM Donor–Acceptor Systems for Organic Optoelectronic Devices

Advanced Functional Materials, EarlyView.
The intermolecular and molecule‐substrate interactions and resulting molecular assembly of the OLED and OPV donor and acceptor molecules BF‐DPB and BPyMPM are investigated on different single crystalline substrates using high‐resolution scanning probe microscopy.

General theory of asymmetric steric interactions in electrostatic double layers [PDF]

arXiv, 2015
We study the Poisson-Boltzmann equation in the context of dense charged fluids where steric effects become important. We generalise the lattice gas theory by introducing a Flory-Huggins entropy for ions of differing volumes and then compare the effective free energy density to other approximations, valid for more realistic equations of state, such as ...

6-Chloro-2,4-bis(dimethylamino)-1,3,5-trimethylborazine

Acta Crystallographica Section E, 2013
The borazine ring of the title molecule, C7H21B3ClN5, shows a mild distortion from a planar to a flattened boat conformation. Steric effects due to the methyl and dimethylamine substituents appear to be the cause of this distortion.

Stationary solutions to the Poisson-Nernst-Planck equations with steric effects [PDF]

arXiv, 2015
Ion transport, the movement of ions across a cellular membrane, plays a crucial role in a wide variety of biological processes and can be described by the Poisson-Nernst-Planck equations with steric effects (PNP-steric equations). In this paper, we shall show that under homogeneous Neumann boundary conditions, the steady-state PNP-steric equations are ...

Non-electrostatic interactions as random fields in charged liquids [PDF]

PhysRevE.111.025407(2025)
We derive an equation capable of treating both the electrostatic and non-electrostatic interactions in the charged liquids. The equation derived is a complex version of the Poisson-Boltzmann equation, in which the non-electrostatic interactions are transformed to complex random fields by the field theory. Thus, the non-electrostatic interactions of the

Ternary Thermosensitive Hydrogel‐Encapsulated Macrolactam Heneicosapeptide Eliminates Epidermal Multidrug‐Resistant Bi‐Microbial Colonization

Advanced Functional Materials, EarlyView.
The co‐existence of Gram‐negative Pseudomonas aeruginosa and Gram‐positive Staphylococcus aureus superbugs in open wounds exacerbates the difficulty of rational treatments. This study develops a hydrogel comprised of poloxamer, hyaluronic acid, and a de novo designed antimicrobial cyclic peptide.

Implications of Interactions between Steric Effects and Electrical Double Layer Overlapping Phenomena on Electro-Chemical Transport in Narrow Fluidic Confinements [PDF]

arXiv, 2010
In this paper, we study the non-trivial interactions between the ionic Steric effects and Electric Double Layer (EDL) overlap phenomenon on the resultant electro-chemical transport in narrow fluidic confinements. Through a comprehensive mathematical model, we demonstrate that more prominent Steric effects may result in greater magnitudes of the channel
