Rationalizing Phonon Dispersion: an Efficient and Precise Prediction of Lattice Thermal Conductivity

Lattice thermal conductivity strongly affects the applications of materials related to thermal functionality, such as thermal management, thermal barrier coatings and thermoelectrics. In order to understand the lattice thermal conductivity more quantitatively and in a time- and cost-effective way, many researchers devoted

Brazilian Researcher and US Army Lab Partner to Develop Materials Science Breakthroughs

The U.S. Army is on the hunt for new materials science breakthroughs by working together with a researcher from Brazil. The U.S. Army Research Laboratory has a cooperative research and development agreement with the Pontifícia Universidade Católica do Rio de Janeiro, known

Supercomputer Predicts Optical and Thermal Properties of Complex Hybrid Materials

Materials scientists at Duke University computationally predicted the electrical and optical properties of semiconductors made from extended organic molecules sandwiched by inorganic structures. These types of so-called layered “hybrid organic-inorganic perovskites”—or HOIPs—are popular targets for light-based devices such as solar cells and

Adding Nanoparticles to a Polymer Matrix Enhances the Thermo-Mechanical Properties of the Materials

A*STAR researchers have toughened up polylactic acid while maintaining its elasticity by adding core-shell nanoparticles as a filler. Polylactic acid (PLA) is a biodegradable and highly biocompatible polymer with good thermal processibility, which has found widespread use in biomedical applications and as
