Viral RNAs are unusually compact. [PDF]

open access: yes, 2014
A majority of viruses are composed of long single-stranded genomic RNA molecules encapsulated by protein shells with diameters of just a few tens of nanometers.

Planar Large Core Polymer Optical 1x2 and 1x4 Splitters Connectable to Plastic Optical Fiber [PDF]

open access: yes, 2013
We report about new approach to design and fabricate multimode 1 x 2 and 1 x 4 Y optical planar power splitter suitable for low-cost short distance optical network. The splitters were designed by beam propagation method using BeamPROP™ software.

FTIR spectroscopic and thermogravimetric characterization of ground tyre rubber devulcanized by microwave treatment [PDF]

open access: yes, 2016
In this work the phenomena involved with the microwave devulcanization of ground tyre rubber (GTR) were investigated. During studies three types of GTR characterized by different content of organic compounds (elastomers, plasticizers, etc..), carbon ...

Phonon-driven ultrafast exciton dissociation at donor-acceptor polymer heterojunctions

open access: yes, 2007
A quantum-dynamical analysis of phonon-driven exciton dissociation at polymer heterojunctions is presented, using a hierarchical electron-phonon model parameterized for three electronic states and 24 vibrational modes.

Polysaccharide Nanostructures [PDF]

open access: yes, 2014
Polysaccharides are carbohydrate polymers where sugar units are linked together through glycosidic linkages. In living organisms polysaccharides are the structural polymers that provide support (e.g., cellulose in plants or chitin in arthropods) or ...

State Dependent Ring Polymer Molecular Dynamics for Investigating Excited Nonadiabatic Dynamics

open access: yes, 2019
Recently proposed non-adiabatic ring polymer molecular dynamics (NRPMD) approach has shown to provide accurate quantum dynamics by incorporating explicit electronic state descriptions and nuclear quantizations.

Equilibrium gels of limited valence colloids

open access: yes, 2017
Gels are low-packing arrested states of matter which are able to support stress. On cooling, limited valence colloidal particles form open networks stabilized by the progressive increase of the interparticle bond lifetime.

The preparation of new perfluoroether fluids exhibiting excellent thermal-oxidative stabilities [PDF]

open access: yes
A series of low molecular weight perfluoroalkylethers (PFAE) were synthesized by direct fluorination. Viscosity-temperature properties and oxidation stabilities were determined. Viscosity-temperature correlations indicated that increases in branching and
