Theoretical physicists unveil one of the most ubiquitous and elusive concepts in chemistry

03-Jul-2019

Even if we study them at school, oxidation numbers have so far eluded any rigorous quantum mechanical definition. A new SISSA study, published in Nature Physics, reverses this state of affairs by providing such a definition, based on the theory of topological quantum numbers, which was honoured ...

How to separate nanoparticles by “shape”

New strategy to separate molecules

13-Jun-2019

In our daily lives, the purpose and function of an item is defined by either its material, e.g. a rain jacket is fabricated of water-proof material, or its shape, e.g. a wheel is round to enable a rolling motion. What is the impact of the two factors on the nanoscale? The impact of material, ...

A periodic table of molecular knots

A repertoire as-yet-undiscovered molecular knots for future physico-chemical applications

06-Aug-2018

Consider a short piece of rope: could you guess which knots are more likely to form if you crumple and shake it? Synthetic chemists have long been working on a molecular version of this problem and, so far, have succeeded at synthesizing half a dozen different knots types using molecular ...

The superionic form of water

Scientists predicted the existence of a new form of water in 1999: That existence has just been confirmed

23-Feb-2018

An original state, both solid and liquid at the same time: this is the latest news on a substance -water- so familiar to everyone but which appears to hold always fresh surprises for scientists. Its name is "superionic water"; it doesn't exist on Earth but it could be abundant inside certain ...

Nanoparticles on nanosteps

02-Mar-2016

Platinum is one of the costly metals used as catalysts in new technologies employed for industrial chemical processes, renewable energy sources, pollution control and many other purposes. In particular, it is used for fuel cells, devices that turn chemical energy directly into electrical energy, ...

The quantum dance of oxygen

Proposal for a new phase of the element, where atoms dance in quartets

09-Jul-2014

Perhaps not everyone knows that oxygen has– quite unusually for such a simple molecule – magnetic properties. The phase diagram of solid oxygen at low temperatures and high pressures shows, however, several irregularities (for example, proper "information gaps" with regard to these magnetic ...

It looks like rubber but isn't

What goes on in a concentrated solution of circular polymers?

25-Mar-2014

The experimental and numerical study of the behaviour of polymers in concentrated solutions is a line of research that is still highly active. In the past, it enabled us to understand why materials like rubber have certain elastic properties. A distinctive feature of these systems is that the ...

Molecules as circuits

The Kondo effect can improve a molecule's conductivity

27-Jan-2014

Silicon-based electronics has certain limits, in the physical sense of the word: this type of circuit can never become "nano" because of the physical laws governing the flow of electrons. This imposes a halt to the process of miniaturization of electronic devices. One of the possible solutions is ...

How do cold ions slide?

Exploring friction by simulating toy-like systems

28-May-2013

Things not always run smoothly. It may happen, actually, that when an object slides on another, the advancement may occur through a 'stop and go' series in the characteristic manner which scientists call "stick-slip", a pervasive phenomenon at every scale, from earthquakes to daily-life objects, ...
