In a surprise move, honeybee tongue hairs repel water

A honeybee pokes out its tongue—which is densely covered in hairs—to lap up nectar and other liquids. Now, researchers report in ACS Applied Materials & Interfaces that those hairs are water repellent. That's unexpected, ...

New models to explore the microstructure of polymer mixtures

A well-known method for making polymer materials is to blend or mix multiple polymers. For disperse blends, two liquid polymers do not mix well with each other, leading to a so-called droplet-in-matrix microstructure which ...

New tool changes the game for heterogeneous material modeling

The performance and safety of lithium-ion batteries (LIB) can be attributed to complex electrode microstructures. Microstructure analysis at the National Renewable Energy Laboratory (NREL) aims to apply in-depth knowledge ...

Two-photon polymerization of PEGda hydrogel microstructure

The fabrication of shape-memory hydrogel scaffolds not only requires biocompatibility, micrometer resolution, high mechanical strength, but also requires a low polymerisation threshold in high-water content environment to ...

A charge-density-wave topological semimetal

Topological materials are characterized by unique electronic and physical properties that are determined by the underlying topology of their electronic systems. Scientists from the Max Planck Institutes for Microstructure ...

Compound may magnetically outperform neodymium magnets

NIMS and Tohoku Gakuin University have developed a boron-doped anisotropic Sm(Fe0.8Co0.2)12 thin film containing only small amount of rare earth elements. The compound exhibited 1.2 tesla coercivity, sufficient for use in ...

Strong and ductile Damascus steels by additive manufacturing

Dr. Philipp Kürnsteiner, Prof. Eric Jägle and their team at the Max-Planck-Institut für Eisenforschung (MPIE) designed, together with colleagues from the Fraunhofer Institute for Laser Technology, a new strong and ductile ...

Microstructure

Microstructure is defined as the structure of a prepared surface or thin foil of material as revealed by a microscope above 25× magnification. The microstructure of a material (which can be broadly classified into metallic, polymeric, ceramic and composite) can strongly influence physical properties such as strength, toughness, ductility, hardness, corrosion resistance, high/low temperature behavior, wear resistance, and so on, which in turn govern the application of these materials in industrial practice.
