We’ve finally transcended Blender and managed to create a hyperrealistic model of a plant.
We’ve already talked about the “quantum internet” in several occasions. The Netherlands is making a huge effort in this field. But this new update comes from Barcelona (Spain). Nicolas Maring etal. (ICFO) has transferred quantum information between a solid crystal and a cloud of cold atomic gas. The result was published in Nature in November 2017.
The transference of qubits between nodes is of key importance in the construction of the so called “quantum internet”. This nodes can be made out of different types of matter so they can perform different functions. While we now know how to transfer information between similar systems, it was not straightforward how to do that using radically different matter configurations.

One of the issues of nanocircuits is heat dissipation. As in the macro world, at the nanoscale, it is imperative to find a way to cool circuits. Thanks to a collaboration between the University of Michigan and the Universidad Autónoma de Madrid, has been proved that a particular arrangement of molecules in nanocircuits, achieves and optimizes molecular termoelectric refrigeration.
This result has been published in Nature Nanotecnology.
Prof. Pedro de Pablo (Nanoforces Lab) has been using atomic force microscopy to break viruses for a while. Apart from the obvious pleasure that breaking things produces, their main focus is to study the stability of viruses. Viruses infect cells by releasing their highly packed genetic material. So the understanding of the stability of the viruses capsides will offer new venues for the development of novel antiviral strategies [article].
Several modern applications require antireflective transparent materials. We try to avoid reflections in our screens and clean transparent coatings are essential in solar panels. Scientists have been looking for a clean, cheap and durable solution for quite long. And this is exactly what Prof. Isabel Rodriguez et al. have recently reported in Nanoscale.
Thanks to this collaboration (IMDEA Nanociencia & IMDEA Materiales) a new coating system has been developed. The methodology involves the fabrication of sub-wavelength moth-eye nanofeatures onto transparent surface composite films in a combined processing step of nanoparticle coating and surface nanoimprinting.
With this approach they’ve been able to reduced the optical reflection losses from values of 9% of typical PMMA plastic films to an optimum value of 0.6%.
We made this picture (which appeared in the back cover of Nanoscale) with the supervision of Prof. Rodriguez. It represent both the high transmission coefficient of this new coating system and its durability.
Cocaine happens to be one of the most illicit drugs in Europe and US. Yet, estimations say there are around 17 million users worldwide. This together, makes important the detection of cocaine and having devices able to precisely measure a wide range of cocaine concentrations in street samples. At TU Delft, together with the Netherlands Forensic Institute Lukasz Poltorak et al. have proposed a successful method which allows not only the detection of very different concentrations of cocaine but also the analysis and detection of cutting agents.
It is hard to imaging the making of the first transistor, now that we make them by the millions. How did we went from making a single, precious and delicate transistor to its mass production?
In a way we are living that very same moment with quantum entanglement (QE). Just months ago the QE of two particles meant a huge achievement. Today, ‘on demand’ entanglement links have been reported in Nature. Quantum entanglement is the pillar of a secure quantum internet. So a way to establish fast and stable links between particles is needed. Thanks to Prof. R. Hanson (QuTech and Kavli Institute of Nanoscience, TuDelft), we are at the verge of QE mass production.
As it is explained at TuDelft website “First of all, they demonstrated a new entanglement method. This allows for the generation of entanglement forty times a second between electrons at a distance of two metres. Peter Humphreys, an author of the paper, emphasises: ‘This is a thousand times faster than with the old method.’ In combination with a smart way of protecting the quantum link from external noise, the experiment has now surpassed a crucial threshold: for the first time, entanglement can be created faster than it is lost.”
Michel van Baal kindly asked for our help in the making of a picture of quantum network. We feel kind of proud been close witnesses of these important discoveries.
