Highly-branched poly(N-isopropyl acrylamide)s with core-shell morphology below the lower critical solution temperature [PDF]
, 2014 YesHighly-branched poly(N-isopropyl acrylamide)s in water pass through coil-to-globule transitions. Using calorimetry and the colour change of a solvatochromic dye within the polymer, we show that some compositions have biphasic core–shell morphologies,

Lower Critical Solution Temperature in Aqueous Solutions of N-Alkyl-Substituted Polyacrylamides [PDF]
Polymer Journal, 1999 The structures and properties of N-alkyl-substituted polyacrylamides (PAA) were studied by FT-IR spectroscopy. For N-alkyl-substituted PAA with lower critical solution temperature (LCST), a specific H-bonded cyclic structure involving alkyl amide units of a polymer and hydroxyl functions of water was observed and found responsible for polymer ...

Thermoresponsive poly(N-vinylcaprolactam) as stationary phase for aqueous and green liquid chromatography [PDF]
, 2010 Poly(N-vinylcaprolactam) (PVCL) connected to aminopropyl silica is a new stationary phase for temperature responsive liquid chromatography (TR-LC). PVCL shows a transition from hydrophilic to hydrophobic interaction between 30 and 40 degrees C.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes
FEBS Letters, EarlyView.The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

New parametrization method for dissipative particle dynamics [PDF]
, 2007 We introduce an improved method of parameterizing the Groot-Warren version of Dissipative Particle Dynamics (DPD) by exploiting a correspondence between DPD and Scatchard-Hildebrand regular solution theory.

FEBS Letters, EarlyView.Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

Entropy Rules: Molecular Dynamics Simulations of Model Oligomers for Thermoresponsive Polymers
Entropy, 2020 We attempted to attain atomic-scale insights into the mechanism of the heat-induced phase transition of two thermoresponsive polymers containing amide groups, poly(N-isopropylacrylamide) (PNIPAM) and poly(2-isopropyl-2-oxazoline) (PIPOZ), and we ...

Synthesis of Amphiphilic Three-Armed Star Random Copolymers via Living Radical Polymerization and their Unimolecular Folding Properties in Water [PDF]
, 2015 Amphiphilic three-armed star random copolymers were synthesized by ruthenium-catalyzed living radical copolymerization of hydrophilic poly(ethylene glycol) methyl ether methacrylate (PEGMA) and hydrophobic dodecyl methacrylate (DMA).
