Physicists find weak spots in ceramic/graphene composites

Physicists and materials scientists from Peter the Great St.Petersburg Polytechnic University (SPbPU) analyzed the structures in nanomaterials made of ceramic and graphene plates, in which cracks appear most frequently. The ...

These pink sea urchins have teeth that sharpen themselves

Sea urchins have five teeth, each held by a separate jaw in a circular arrangement at the center of their spiked, spherical bodies. Now, researchers reporting in the journal Matter on September 18 have discovered how the ...

Simple and low-cost crack-healing of ceramic-based composites

A team of researchers at Osaka University demonstrated that cracks induced in composites consisting of alumina ( Al2O3) ceramics and titanium (Ti) as dispersed phase could be healed at room temperature, a world first. This ...

Multifunctional dream ceramic matrix composites are born

Researchers at Osaka University have produced composites consisting of alumina (AI2O3) ceramics and titanium (Ti), namely AI2O3/Ti composites. They designed a percolation structure for forming a continuous conduction pathway ...

A tougher conductive ceramic at lower cost

By systematically refining standard processing techniques, A*STAR researchers have developed a low-cost method for manufacturing an electrically conductive aluminum oxide ceramic composite—a hard-wearing material used in ...

Nuclear materials developed for a sustainable future

An EU-funded project has fostered links between national and European programmes to harmonise and implement scientific and technical research into materials for a safe and sustainable nuclear sector.

Rapid ceramic-metal processing for superior composites

Recent advancements in automotive, aerospace and power generation industries have inspired materials scientists to engineer innovative materials. Ceramic metal composites, or cermets, are an example of a new and improved ...

Ceramic matrix composites take flight in LEAP jet engine

Ceramic matrix composite (CMC) materials are made of coated ceramic fibers surrounded by a ceramic matrix. They are tough, lightweight and capable of withstanding temperatures 300–400 degrees F hotter than metal alloys ...
