Gravitational Wave Heating of Stars and Accretion Disks
, 2012 We investigate the electromagnetic (EM) counterpart of gravitational waves (GWs) emitted by a supermassive black hole binary (SMBHB) through the viscous dissipation of the GW energy in an accretion disk and stars surrounding the SMBHB. We account for the

Advanced Functional Materials, EarlyView.Stretchable p/n‐pair Ag@Ag2Se TE fibers are developed for next‐generation fiber‐based electronics. The TE fibers maintain excellent electrical conductivity and a high Seebeck coefficient under strain. Integrated into textiles, they enable simultaneous temperature and strain sensing, as well as energy harvesting, offering great potential for ...

Reconnection rates, small scale structures and simulations [PDF]
The study of reconnection in the context of one fluid, two dimensional magnetohydrodynamics (MHD), with spatially uniform constant density, viscosity and resistivity is though to retain most of the physics important in reconnection.

Robust and Reversible Thermofluorescence in Solvent‐Free Thermoplastic Polyurethane Composites
Advanced Functional Materials, EarlyView.Thermofluorescent polymer composites with high‐contrast optical outputs are prepared by solvent‐free blending of indenoquinacridone dye into a thermoplastic polyurethane matrix. The temperature‐dependent fluorescence originates from aggregation–dissociation of the dye molecules, regulated by competing hydrogen bonds from the polymer matrix.

Some physical properties of chitosan in propionic acid solutions [PDF]
Maejo International Journal of Science and Technology, 2007 Surface tensions, contact angles and conductivities of propionic acid solutions containing different amounts of chitosan were measured at a room temperature to a temperature accuracy of 0.2. The value of critical coagulation concentration (CCC) was then

Influence of Different Polymer Types on the Overall Release Mechanism in Hydrophilic Matrix Tablets
Molecules, 2009 The effect of three different types of polymer chain structures on the polymer release from hydrophilic matrix tablets was investigated by comparing a synthetic semi-crystalline linear polymer (PEO), a branched amorphous polysaccharide (dextran) and an ...

Advanced Functional Materials, EarlyView.Viscoelasticity‐driven instabilities are harnessed to create tunable, periodic textures in 3D‐printed liquid crystalline polymers. This study illustrates how processing parameters control these spontaneous meso‐scale patterns. These unique structural architectures unlock new possibilities for functional devices, ranging from photonic components to ...

Stiffness of chitosan in solution through intrinsic viscosity measurements
Revista Facultad de Ingeniería Universidad de Antioquia, 2012 Chitosan is the partially deacetylated derivative from chitin. It is very significant to understand the behavior of chitosan as a polyelectrolyte, since most of chitosan final applications are related with its aqueous solutions.
