Russia is developing a new 4th generation combat armor Sotnik. It claims can resist .50 caliber rounds.
Category: Materials
Flexible material can allow optical camouflage
Was developed a new material, which can create flexible displays and optical camouflage like in movies and games.
Organic membranes for water desalinization
High-efficiency polyamide membranes can be used in water desalinization, thanks to the homogenous internal structure.
3D printer: How it works?
The 3D printer is revolutionizing object manufacturing. It’s an additive manufacturing technology, whose operation is today’s subject.
The first room-temperature superconductor
Was discovered a material which becomes a superconductor at 15ºC, after more than a century of search.
Chitin: Construction material for Mars?
A new study suggests use chitin to build structures and tools on Mars, for future colonies on the red planet.
Graphene oxide and the reduced form
Graphene is still too expensive and difficult to make on large scale. While graphene oxide is a graphite derivate, which is cheaper and easier to manufacture.
Introduction to nanomachines
Nanomachines are molecular mechanisms which execute a function when receive a stimulus. Today’s subject is an introduction with examples.
MEMS manufacturing (Part 2, surface micromachining)
In this part about MEMS manufacturing, the subject is surface micromachining. A very different method from the one shown in previous part.
MEMS manufacturing (Part 1)
MEMS manufacturing is similar to process used to fabricate microelectronic circuits. The bulk micromachining is today’s subject.
