Peroxydisulfate initiated synthesis of potato starch-graft-poly(acrylonitrile) under microwave irradiation

open access: yeseXPRESS Polymer Letters, 2007
Potato starch-graft-poly(acrylonitrile) could be efficiently synthesized using small concentration of ammonium peroxydisulfate (0.0014M) in aqueous medium under microwave irradiation.

Preparation of aromatic polyamidines and their transformation in polybenzimidazoles

open access: yeseXPRESS Polymer Letters, 2014
Polymers with amidine groups –NH–C(=NH)– in main chain were synthesized by two different approaches. The first strategy consists in polyaddition of dinitriles and diamines in acidic ionic liquids (ILs) which act as catalyst and solvent, while the second ...

Examination of the Molecular Mass of Polyhydroxypolyamides [PDF]

open access: yes, 2010
The work described in this thesis investigated the use of size exclusion chromatography (SEC) to fractionate a variety of different polyhydroxypolyamide (PHPA) samples for analysis by matrix assisted laser desorption ionisation-time of flight ...

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

open access: yesFEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

Liquid crystalline polymers IX Main chain thermotropic poly (azomethine – ether)s containing thiazole moiety linked with polymethylene spacers

open access: yeseXPRESS Polymer Letters, 2007
A new homologous series of thermally stable thermotropic liquid crystalline poly(azomethine-ether)s based on thiazole moiety were synthesized by solution polycondensation of 4,4`-diformyl-α,ω-diphenoxyalkanes, I–IV or 4,4`-diformyl-2,2 ...

Sequential graft-interpenetrating polymer networks based on polyurethane and acrylic/ester copolymers

open access: yeseXPRESS Polymer Letters, 2016
Highly transparent and tough graft-interpenetrating polymer networks (graft-IPNs) were synthesized using an elastomeric polyurethane phase (PU) and a highly stiff acrylate-base copolymer phase.

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

open access: yesFEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.
