CHLOROPHYLL MONOLAYERS IN CHLOROPLASTS [PDF]

open access: yesJournal of General Physiology, 1953
1. The data on the fine structure of the chloroplasts and the chlorophyll analyses, in two algal flagellates, Euglena gracilis and Poteriochromonas stipitata, are consistent with the assumption that the chlorophyll molecules are arranged in monomolecular layers at the interfaces between the lipid (dense) and the aqueous protein complex layers.

Lipid monolayers: action of phospholipase A of Crotalus atrox and Naja naja venoms on phosphatidyl choline and phosphatidal choline

open access: yesJournal of Lipid Research, 1966
The activity of phospholipase A on phosphatidyl choline and phosphatidal choline spread as monolayers on phosphate buffers containing snake venom (Crotalus atrox or Naja naja) was studied by measuring the fall of surface potential as a function of time ...

Platinum modified MoS(2) monolayer for adsorption and gas sensing of SF(6) decomposition products: a DFT study

open access: yesHigh Voltage, 2019
In the long-running of sulphur hexafluoride (SF(6))-insulated equipment, SF(6) inevitably decomposes to various decomposition products under electric discharge, including SOF(2) and SO(2)F(2).

Integration of two-dimensional transition metal dichalcogenides with Mie-resonant dielectric nanostructures

open access: yesAdvances in Physics: X, 2020
Integrating transition metal dichalcogenide (TMD) monolayers with dielectric nanostructures exhibiting Mie-like resonances opens a plethora of opportunities in manipulating their excitonic emission in the near-field and far-field regimes, yielding ...

Distinct Contact Guidance Mechanisms in Single Endothelial Cells and in Monolayers

open access: yesAdvanced Materials Interfaces, 2023
In many tissues, cell shape and orientation are controlled by a combination of internal and external biophysical cues. Anisotropic substrate topography is a ubiquitous cue that leads to cellular elongation and alignment, a process termed contact guidance

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Accurate Simulations of Lipid Monolayers Require a Water Model With Correct Surface Tension [PDF]

open access: yes, 2021
Lipid monolayers provide our lungs and eyes their functionality, and serve as proxy systems in biomembrane research. Therefore, lipid monolayers have been studied intensively also using molecular dynamics simulations, which are able to probe their ...

Ligand-Assisted Formation of Graphene/Quantum Dot Monolayers with Improved Morphological and Electrical Properties

open access: yesNanomaterials, 2020
Hybrid nanomaterials based on graphene and PbS quantum dots (QDs) have demonstrated promising applications in optoelectronics. However, the formation of high-quality large-area hybrid films remains technologically challenging.

Transverse electric/magnetic switchable absorption ring modulator based on graphene

open access: yesIET Optoelectronics, 2021
We propose a transverse electric (TE)/transverse magnetic (TM) switchable absorption ring modulator based on graphene that can operate in either the TE or the TM mode.
