Making the most out of sunlight

Two months ago I posted the news of a start up that found a way to increase the conversion rate of solar light into electricity by stacking different materials and thus covering more wavelength of light. Now I run onto a news of researchers at the mIT that have found an almost …

I can see a use for this…

I guess it is not just me… sometimes looking for something at home and not finding it.  And more than once I wished somebody could tell me where I left the key or that screwdriver I happened to use just minutes ago! Researchers at Georgia Tech might have found a solution: …

The many faces of carbon

Just yesterday I reported the finding of a "magic" paint made of carbon flakes that can make any surface impermeable to fluids and gases. Carbon is indeed a most interesting atoms and scientists are learning to exploit its many configurations that are possibile, some naturally occurring on the Earth (or …

A protective cover a few atoms thick

Graphene, a single layer of carbon atoms arranged in hexagons, is seen by many as the holy Grail of this decade because of its amazing properties: strengths, conductivity, lightness as well as impermeability to liquid and gases. We already have graphene, what we miss is a way of producing it …

Beyond Asimov

Asimov, to me, has always represented the most daring vision of a future that although having some sort of scientific underpinning was basically beyond scientific possibility. However, as time goes by some of Asimov ideas drift into the domain of scientific goals that might be achieved. At the same time, the …

Looking into my genome

As genome sequencing is getting cheaper more and more of us will end up having our genome in our pocket. Having a 2 GB of A-C-G-T strings is not particularly exciting though. What we would like to have is some sort of indication of their meaning, the probability to run …

Cooling down electrons

To cool down electrons you can place them in a "fridge". Suppose you have a chip. TO cool down the electrons flowing in the chip transistors you can place the chip in liquid nitrogen and as the chips cools down so do the electrons flowing through it. This approach does …

Sensing single molecules

Researchers at the University of California, Santa Barbara, have been able to demonstrate a sensors that can detect single molecules, a holy grail for preventive medicine. Imagine being able to detect since cancerous cells … This has been possible by using MoS2, molybdenum disulfide, of which I posted a news just …
