The behaviour of fatty acid vesicles in prebiotically plausible environments
… vesicles in environments of mechanical stress, monovalent salt and particles including minerals. I also explored the effect of RNA-relevant divalent cations on fatty acid vesicles, as well as changes due to pH fluctuation. The findings of this project suggest that fatty acid vesicles are able to …

ΚΑΘΑΡΙΣΜΟΣ ΚΑΙ ΙΔΙΟΤΗΤΕΣ ΤΡΙΩΝ ΚΥΤΤΑΡΟΠΛΑΣΜΑΤΙΚΩΝ ΡΙΒΟΝΟΥΚΛΕΑΣΩΝ ΑΠΟ ΣΥΚΩΤΙ ΠΟΝΤΙΚΟΥ
… RNA OPTIMALLY AT PH 6.2, IN THE ABSENCE OF SALTS AND AT PH 5.5 IN SOLUTIONS WITH 150 MM OF MONOVALENT SALTS. IT IS NOT AFFECTED BY MG+2, ATP AND EDTA, BUT IT IS INHIBITED BY CA+2 AND ZN+2. IT IS ACID RESISTANCE AND HEAT LABILE. IT HYDROLYSES POLYPYRIMIDINORIBONUCLEOTIDES AND RNA IN NP-U AND …

Limiting membrane and diffusion behavior of a compacted sand-bentonite mixture for hydraulic and chemical containment
… (by dry weight) by determining the threshold salt concentration at which measurable membrane behavior was eliminated. The specimens were exposed to a series of boundary monovalent salt solutions with increasingly higher source concentrations, Cot, until measured values of the membrane …

Layer by Layer, Nano-particle "Only" Surface Modification of Filtration Membranes
… percentage of rejection of standard bivalent and monovalent salt solutions using steady cross flow permeation experiments. The results confirm rejection of at least 60% of even the smallest dextrans, an estimated dextran MWCO of 20 KDa, and rejection of 10% and 20% for monovalent (NaCl) and …

Synthesis and Characterization of Linear and Crosslinked Mono-Sulfonated Poly(arylene ether sulfone)s for Reverse Osmosis Applications
… drawbacks that jeopardize effective levels of salt rejection in order to achieve high water flux. In mixed salt feed sources, monovalent salt rejection decreases when divalent cations such as Ca2+ bind with the anionic sulfonate groups to cause charge screening, and this can lead to too much …

Molecular dynamics simulations of polyelectrolyte brushes
… of charged monomers, counterions, and salt ions is treated explicitly. The polymer chains are anchored by one of their ends to a uncharged planar surface. The chains are treated under good solvent conditions. Monovalent salt ions (1:1 type) are modelled same as counterions. The studies …

Novel Monomer Design for Next-Generation Step-Growth Polymers
… for the ionically-endcapped PEIs. The divalent salts demonstrated higher mechanical strength and melt viscosities compared to the monovalent salt and the non-ionic PEIs. Interestingly, the zinc-endcapped PEI series exhibited decreased high-shear viscosities compared to the other PEIs, lending to …

Interfacial behavior of RNA-free MS2 bacteriophage particles
The effect of genomic material on the effective surface charge a viral capsid was investigated in this study. The RNA of bacteriophage MS2 was removed and the empty capsid characterized and compared to intact MS2. Transmission electron microscopy was used to ensure that the MS2 capsid was intact …
