Human brain has about 85 billion neurons. Each neuron forms thousands of chemical and electrical synapses with other neurons. To record the synaptic activity of each neuron in the brain an intracellular probe with a millivolt scale is required. Glass electrodes are widely used, but they are fragile and they have high impedance. An intracellular […]
Have you ever observed how a drop of coffee dries? As water evaporates, its suspended particles are deposited in a ring-like fashion in a phenomenon known as the coffee-ring effect. Obviously, this effect is undesirable in the numerous practical applications that require a uniform coating. However, the way to avoid it has remained unknown. The […]
Just a few years ago, nanoparticles broke into almost every laboratory in the world in one way or another. It marked a boom in nanoscience and nanotechnology. The demand for these new ultrafine particles, halfway between the bulk scale and the molecule scale, increased in such a way that sometimes there was even a shortage […]
Nowadays we are getting more and more accustomed to making use of new technologies shortly after they have been developed. We like the idea of immediacy and our wishes coincide well with the commercial interests of industry. Nevertheless, there is a field in which this immediacy is almost impossible: the medical sector. Unfortunately, there is […]
If you have ever faced that thankless task of cleaning fish, for sure you will have realized, at least envisaged, the complex architecture of the fish’s natural armour. Fish scales play the role of a skeleton which provides both protection and flexibility at the same time. It goes without saying that this fact has not […]
Thin films are defined as material layers ranging from nanometers to several micrometers of thickness that are deposited onto a matrix in order to modify its physical characteristics. Although solar cells conform a relevant field of application, it may be highlighted that the most important employment of thin film technology lies in the semiconductor industry […]
You have probably heard of the plastic island , an enormous area full of plastic garbage, gathered by oceanic currents, in the North Pacific Ocean. In the last few decades the amount of plastic debris in this area has increased two orders of magnitude, representing one of the best examples of the environmental impact caused […]
