The head and neck cancer (HN-5) cell line properties extraction by AFM

open access: yesJournal of Biological Engineering, 2020
This work incorporates experimental methods based on Atomic Force Microscopy (AFM) in order to extract the physical and mechanical characteristics of the head and neck cancer (HN-5) cell line such as cell topography, modulus of elasticity and ...

Al₂O₃‐Functionalized Carbon Nanomembranes with Enhanced Water Permeance and Selectivity for Efficient Air Dehumidification

open access: yesAdvanced Functional Materials, EarlyView.
Carbon nanomembranes with ultra‐thin Al2O3 functionalization are less than 15 nm thin and exhibit outstanding permeation performance with a water vapor/nitrogen selectivity higher than 1 × 104, twice that of pristine CNMs, and an exceptionally high water vapor permeation rate for potential applications in air dehumidification.

Intermolecular vs molecule–substrate interactions: A combined STM and theoretical study of supramolecular phases on graphene/Ru(0001)

open access: yesBeilstein Journal of Nanotechnology, 2011
The competition between intermolecular interactions and long-range lateral variations in the substrate–adsorbate interaction was studied by scanning tunnelling microscopy (STM) and force field based calculations, by comparing the phase formation of (sub-)

Discontinuous transition of molecular-hydrogen chain to the quasi-atomic state: Exact diagonalization - ab initio approach

open access: yes, 2015
We obtain in a direct and rigorous manner a transition from a stable molecular hydrogen $nH_2$ single chain to the quasiatomic two-chain $2nH$ state. We devise an original method composed of an exact diagonalization in the Fock space combined with an ab ...

Spreading of a liquid drop over a plane rigid substrate due to intermolecular forces [PDF]

open access: yesarXiv, 2008
Self-similar solutions of the equation that describes spreading of a liquid layer due to intermolecular forces are found. It is supposed that, when the thickness of the layer reaches some magnitude of the order of the molecular size, it turns into a monomolecular layer, which can be liquid or gaseous.

Energy Transfer within the Hydrogen Bonding Network of Water Following Resonant Terahertz Excitation [PDF]

open access: yesarXiv, 2020
Energy dissipation in water is very fast and more efficient than in many other liquids. This behavior is commonly attributed to the intermolecular interactions associated with hydrogen bonding. Here, we investigate the dynamic energy flow in the hydrogen-bond network of liquid water by a pump-probe experiment.

Development of a Novel, All‐Aromatic High Tensile Modulus Liquid Crystalline Polyimide for Fused Filament Fabrication Applications

open access: yesAdvanced Functional Materials, EarlyView.
A novel, high tensile modulus, fully aromatic thermotropic liquid crystalline polyimide (LCPI) with better solvent resistance and thermal stability is synthesized. Tensile specimens are fabricated using both injection molding and FFF processes, accomplished via lower viscosity enabled by the LC phase.

Highly Crystalline Selenium‐Substituted C‐Shaped Ortho‐Benzodipyrrole‐Based A‐D‐A‐Type Nonfullerene Acceptor Enabling Solution‐Processed Single‐Crystal‐Like Thin Films for Air‐Stable, High‐Mobility N‐Type Transistors

open access: yesAdvanced Functional Materials, Volume 35, Issue 15, April 10, 2025.
Symmetric selenium‐substituted CB‐2Se forms a highly ordered, kaleidoscope‐like 3D single‐crystal structure with enhanced intermolecular interactions, enabling solution‐processed single‐crystal‐like thin film, which transitions from a kinetically trapped face‐on π–π stacking orientation to a thermodynamically stable edge‐on configuration upon thermal ...

Divalent metal ions under low concentration environment improved the thermal gel properties of egg yolk

open access: yesPoultry Science
: To improve the thermal gel properties of egg yolk, the effect of several valence metal ions (K+, Ca2+, Mg2+ and Fe3+) with different concentrations (0–0.72%) on the rheological, gel, and structural properties of egg yolk were investigated.
