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.

Microwave heating improves artificial bone

An artificial bone scaffold produced by researchers in South Korea could enhance the treatment of bone damage and defects through bone grafts.

Radiation boost for artificial joints

A blast of gamma radiation could toughen up plastic prosthetic joints to make them strong enough to last for years, according to researchers in China writing in the current issue of the International Journal of Biomedical ...
