Effects of pressure on systems with intrinsic orientational order
TLDR
In this paper, the dynamics of shape-persistent macromolecules have been investigated to the same extent as of glass-forming liquids or amorphous polymers, and it has been shown that these molecularly diverse but shape-perceptible macromoles share some common features in their dynamic response.About:

Supercooled dynamics of glass-forming liquids and polymers under hydrostatic pressure
TL;DR: In this paper, a review of the mechanisms underlying the relaxation properties of glass-forming liquids and polymers is provided, with an emphasis in the insight provided into the mechanism underlying the glass relaxation properties.

Polypeptides and 100 years of chemistry of alpha-amino acid N-carboxyanhydrides.
TL;DR: This review summarizes the literature after 1985 and reports on new aspects of the polymerization processes, such as the formation of cyclic polypeptides or novel organometal catalysts and the role of NCAs in molecular evolution on the prebiotic Earth is discussed.
Journal ArticleDOI
Macromolecular engineering: From rational design through precise macromolecular synthesis and processing to targeted macroscopic material properties
TL;DR: In this paper, the authors discuss the recent advances in control over various polymerization systems, including ionic, radical, coordination and even polycondensation have enabled synthesis of many new well-defined (co)polymers and some of them are briefly discussed.

TL;DR: Application of pressure results in the thermodynamic phase diagram that shows increasing stability of the crystalline phase at elevated pressures and suggest new thermodynamic and kinetic pathways that favor the phase with the highest charge carrier mobility.

Origin of the α, β, (βα), and “Slow” Dielectric Processes in Poly(ethyl methacrylate)
TL;DR: In this paper, the dynamics in poly(ethyl methacrylate) (PEMA) were studied as a function of temperature (in the range from 133.15 to 453.15 K), pressure (0.1 to 300 MPa), and molecular weight (2.0 × 103 and 1.59 × 104 g/mol) for frequencies from 3 × 10−3 to 106 Hz using dielectric spectroscopy.

A complex plane representation of dielectric and mechanical relaxation processes in some polymers
S. Havriliak,S. Negami +1 more
TL;DR: In this paper, it was shown that the complex deformation of the same data can be represented by a function of same form but with different values for the constants, which can be interpreted as the decay of the distortion with time of the removal of stress field.

Dynamical transition of myoglobin revealed by inelastic neutron scattering.
TL;DR: The dynamical behaviour of myoglobin (and other globular proteins) suggests a coupling of fast local motions to slower collective motions, which is a characteristic feature of other dense glass-forming systems.

Solvent mobility and the protein 'glass' transition.
TL;DR: A novel molecular dynamics simulation procedure with the protein and solvent at different temperatures has been used, showing the essential role of solvent in controlling functionally important protein fluctuations above 180 K.
