An investigation of the interaction of N2O with the Si(111)-7 × 7 surface using AES and optical reflectometry; A comparison with O2 [PDF]

open access: yes, 1984
At 300 K, N2O decomposes into N2, leaving behind atomic oxygen at the Si(111)¿7 × 7 surface. Decomposition at two different sites is proposed, having the overall initial reaction probability: s(0) = (6.7 ± 0.7) × 106.

Towards Exciton-Polaritons in an Individual MoS2 Nanotube

open access: yesNanomaterials, 2020
We measure low-temperature micro-photoluminescence spectra along a MoS 2 nanotube, which exhibit the peaks of the optical whispering gallery modes below the exciton resonance.

Human Cholangiocytes Form a Polarized and Functional Bile Duct on Hollow Fiber Membranes

open access: yesFrontiers in Bioengineering and Biotechnology, 2022
Liver diseases affect hundreds of millions of people worldwide; most often the hepatocytes or cholangiocytes are damaged. Diseases of the biliary tract cause severe patient burden, and cholangiocytes, the cells lining the biliary tract, are sensitive to ...

Dynamics of a Monolayer of Microspheres on an Elastic Substrate [PDF]

open access: yes, 2015
We present a model for wave propagation in a monolayer of spheres on an elastic substrate. The model, which considers sagittally polarized waves, includes: horizontal, vertical, and rotational degrees of freedom; normal and shear coupling between the ...

Synthesis and physicochemical evaluation of fluorinated lipopeptide precursors of ligands for microbubble targeting

open access: yesBeilstein Journal of Organic Chemistry, 2021
Ligand-targeted microbubbles are focusing interest for molecular imaging and delivery of chemotherapeutics. Lipid–peptide conjugates (lipopeptides) that feature alternating serine–glycine (SG)n segments rather than classical poly(oxyethylene) linkers ...

Chemoresponsive monolayer transistors [PDF]

open access: yesProceedings of the National Academy of Sciences, 2006
This work details a method to make efficacious field-effect transistors from monolayers of polycyclic aromatic hydrocarbons that are able to sense and respond to their chemical environment. The molecules used in this study are functionalized so that they assemble laterally into columns and attach themselves to the silicon oxide surface of a silicon ...

Solid and Liquid Surface-Supported Bacterial Membrane Mimetics as a Platform for the Functional and Structural Studies of Antimicrobials

open access: yesMembranes, 2022
Increasing antibiotic resistance has provoked the urgent need to investigate the interactions of antimicrobials with bacterial membranes. The reasons for emerging antibiotic resistance and innovations in novel therapeutic approaches are highly relevant ...

Folding Langmuir Monolayers [PDF]

open access: yesPhysical Review Letters, 2002
The maximum pressure a two-dimensional surfactant monolayer is able to withstand is limited by the collapse instability towards formation of three-dimensional material. We propose a new description for reversible collapse based on a mathematical analogy between the formation of folds in surfactant monolayers and the formation of Griffith Cracks in ...
