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 ...

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Synthesis, morphology and rheology of core-shell silicone acrylic emulsion stabilized with polymerisable surfactant

open access: yeseXPRESS Polymer Letters, 2010
Core-shell silicone acrylic emulsions with 3-methacryloxypropyl trimethoxysilane (MPTS) in the shell were prepared by seeded polymerization with the assistance of polymerisable maleate surfactant (MT).

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.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Chemical Synthesis in Elastomer-Based Integrated Microfluidics [PDF]

open access: yes, 2010
There is wide interest in using the unique properties of microfluidic environments for the production of fine chemicals and pharmaceuticals. Compared to bench top synthesis, microfluidic systems engender the significant advantage of superior control of ...

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 ...
