Two-armed 3-D printing

Twin robotic arms work together as part of a project to construct what will be the largest, most complex object ever 3-D printed in titanium: a test version of the 3-m diameter 'optic bench' at the heart of ESA's Athena X-ray ...

Color-changing sparks

Sparks are a fascinating phenomenon well-known from campfires, flint stones and electric sparklers and other pyrotechnic articles. Looking at sparks more closely reveals the limited colors in which they appear. Dark red-orange ...

Strength in numbers for 3-D printing

Additive manufacturing, also called 3-D printing, is commonly used to build complex three-dimensional objects, layer by layer. A*STAR researchers have shown that the process can also help to make a high-performance alloy ...

Chang'e 4 Rover comes into view

On Jan. 30 2019, Lunar Reconnaissance Orbiter Camera (LROC) acquired a spectacular limb shot centered on the Chang'e 4 landing site, looking across the floor of Von Kármán crater. At the time, the Lunar Reconnaissance Orbiter ...

Powder could help cut CO2 emissions

Scientists at the University of Waterloo have created a powder that can capture CO2 from factories and power plants.

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 ...
