The search for bio-compatible materials that can sustain the strain of being implanted in a human heart has been going on for several decades. The problem with the heart is that it beats some 100,000 times a day (there are 86,400 seconds in a day …) and at every beat …

Supercapacitors are … well capacitor with a super capacity in terms of energy storage. Like capacitors they can accumulate energy in a blink of an eye and likewise discharge it. Batteries take more time to be charged (in a capacitor you measure time in seconds, 1 to 10 seconds to …

Graphene is a single layer sheet of carbon atoms bounded one another to form a net of hexagons (see the graphic), a lattice resembling a honeycomb. Graphene was first observed as a layer bonded on metal back in 1962 but was “rediscovered” in 2004 by researchers at the Manchester University …

17. Brain Computer Interfaces The connection of our brain to a computer was in a way imprinted in the name that many gave to the earlier ideas of computers: “Electronic Brains”. If they are both “brains” it makes sense to look for a connection among them: easier said than done. …

Researchers at the University of Manchester have found a way to use graphene for sensing a specific antibody that indicates the presence of an autoimmune disease, the Membranous Nephropathy, a disease of the kidney. They created a protein based layer on graphene that is sensitive to the MN antibodies. When …

We live in a world of energy, continuously fuelled by the Sun (and, in a minimal part, by radioactive decade). Energy as such is no good. What is needed is to transform one form of energy into another one. We use gasoline (chemically stored energy) and by combining it with …

Lithium-ion batteries are today’s state of the art (at least on Earth, if you are planning flying to Mars you will likely turn to different kinds of batteries…). As good as they are, the need for dense energy storage and fast recharging is bigger than what Li-ion can deliver, hence …

Batteries have kept evolving throughout these last decades however the general perception is that they are not increasing their capacity at all. This is due to that fact that we don’t measure a battery in terms of Power (Ah – Ampere hour) nor in terms of capacity density (how many …

I don’t know about you, but when I saw this image on IEEE Spectrum (read the article, it is really worth your time) it reminded me of teeth radiography… It is not.  It is actually an image of a novel type of transistors whose gate size is 3nm, the smallest size …

A group at MIT is looking at the strange properties emerging when two layers of graphene, each one a single atom thick, are layered onto one another at different angles. They are not alone: some other 30 groups, expected to grow to over hundred in the coming two years, are …
