Reduced-mobility layers with high internal mobility in poly(ethylene oxide)-silica nanocomposites.

The Journal of chemical physics

Golitsyn Y, Schneider GJ, Saalwächter K, Hansen SG, Machalicek W.
PMID: 28571377
J Chem Phys. 2017 May 28;146(20):203303. doi: 10.1063/1.4974768.

A series of poly(ethylene oxide) nanocomposites with spherical silica was studied by proton NMR spectroscopy, identifying and characterizing reduced-mobility components arising from either room-temperature lateral adsorption or possibly end-group mediated high-temperature bonding to the silica surface. The study complements...

Cardiac involvement is a well-known feature of neuromuscular diseases. Most commonly cardiac manifestations occur later in the course of the disease. Occasionally severe cardiac disease, including conduction disturbances, life-threatening arrhythmias, and cardiomyopathy, with its impact on prognosis, may be...

Proton conductivity and phase transitions in 1,2,3-triazole.

Physical chemistry chemical physics : PCCP

Pulst M, Balko J, Golitsyn Y, Reichert D, Busse K, Kressler J.
PMID: 26847581
Phys Chem Chem Phys. 2016 Feb 17;18(8):6153-63. doi: 10.1039/c5cp07603j.

1,2,3-Triazole (TR) is a good proton conductor which is tidely related to formation of a hydrogen bond network along the N-HN trajectory and its self-dissociation into diH-1,2,3-triazolium and 1,2,3-triazolate. To gain a deeper understanding, the proton conductivity of TR...

Intensity and Distribution of Patchy Late Gadolinium Enhancement in Left Atrium in Patients With Atrial Fibrillation.

Journal of atrial fibrillation

J Atr Fibrillation. 2019 Oct 31;12(3):2206. doi: 10.4022/jafib.2206. eCollection 2019.

PURPOSE: Late gadolinium enhancement (LGE) cardiac magnetic resonance imaging (MRI) studies were performed on healthy individuals to establish signal intensity thresholds for reproducible left atrial (LA) patchy LGE detection. Using established criteria, differences in LA patchy LGE between healthy...

Ultrastructure and affinity of Lower Carboniferous megaspores from the Moscow Basin, Russia.

Review of palaeobotany and palynology

Rev Palaeobot Palynol. 2000 Mar 01;109(1):1-31. doi: 10.1016/s0034-6667(99)00042-1.

Ten megaspore species isolated from Moscow Basin lignites of Lower Carboniferous (Viséan) age have been studied by scanning and transmission electron microscopy (SEM and TEM). These species belong to seven megaspore genera: Lagenicula, Sublagenicula, Crassilagenicula, Setosisporites, Zonalesporites, Caudatosporites, and...

Both VEGA balloons encountered vertical winds with typical velocities of 1 to 2 meters per second. These values are consistent with those estimated from mixing length theory of thermal convection. However, small-scale temperature fluctuations for each balloon were sometimes...

Basic principles of static proton low-resolution spin diffusion NMR in nanophase-separated materials with mobility contrast.

We review basic principles of low-resolution proton NMR spin diffusion experiments, relying on mobility differences in nm-sized phases of inhomogeneous organic materials such as block-co- or semicrystalline polymers. They are of use for estimates of domain sizes and insights...
