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.
Graphene: Properties and applications
This post’s topic is graphene. It is one of carbon’s allotropic forms and promises to cause a technological revolution due to it’s properties.
The superconductivity phenomenon
Some solids lose all resistance to electrical current in certain conditions. This is the superconductivity phenomenon and today’s subject.
Theoretical superconductor at high temperature
A superconductor based in hydrogen can theoretically work at 200ºC, but needs a very high pressure.
Fluoride batteries are arriving
New materials to create more durable and efficient batteries are wanted. Many companies and laboratories are developing fluoride batteries. Today is shown these batteries and theirs promises.
Graphite
The graphite is an ore made exclusively of carbon with many applications and it is used to produce graphene, a revolutionary material.
News: New definition of kilogram
Has been appeared a new system to kilogram definition. But it will only take effect in 20 May, 2019.
