Magnetic resonance imaging (MRI) has long been used as a non invasive detection technique in scientific research, industry and medicine. However, its low resolution (in the order of millimeters) makes it useless for nanotechnology applications despite its huge potential. And this is were researchers from TU Delft, Leiden University, Tohoku University and the Max Planck […]
There is plenty of room at the bottom. Well, plenty, yes, but not infinite. There is a limit on how small we can build things, or something that happens to be of great technological importance: how faint an electrical current can be. And we might have just found an answer to that. Researchers from the […]
We’ve started a new project called The Saga of the Third Daughter, a series of videos telling the story of the Great Oxidation Event. Interestingly, or so we think, these videos are not designed to be part of an outreach project. We wanted to tell this story as if it was a classic creation myth. […]
Visualizing the behaviour of charge carriers will benefit the design and functionality of semiconductor devices. This, which seems a great idea, seems equally unattainable. However, at Delft University of Technology (The Netherlands) they’re famous for not having any respect for seemingly unattainable challenges. Jacob P. Hoogenboom et al. have developed a technique to visualize “fast […]
Multiple medical and biological sensors and targeted drug delivery are based in the functionalization of nanoparticles (NPs) with biomolecules. The role of the NPs is to enhance the optical response of the target surroundings. But this enhancement comes with a huge risk: this same radiation can severily damage DNA or RNA producing mutations. Johannes Feist […]
If I understand it correctly (and I’m probably not), Andres Castellanos is not only making interesting discoveries in condensed matter physics. He and his collaborators (Kavli Institute of Nanoscience and the University of Teheran) are also actively working on making it easier for others to make advances on this area. How? By making easier to […]
La saga de la Tercera Hija y el alumbramiento del Aire. (y todas las grandes cosas) Canto I Los trabajos de la Fuerza En el principio fue la Fuerza. Y en la Fuerza, moraba la Niebla, que era tan vieja como el mundo. Y era tenue y ligera, pero también impaciente y turbulenta. Y en […]
Magnetic skirmions are quasiparticles which present extended configurations (or textures) of spins and their physics are of great interest since they could be used in spintronics as sensors or memory storage devices. Its manipulation and tailoring is thus of great importance. In a recent work published in Nanoscale, a group led by Prof. Agustina Asenjo, […]
With today’s free tools and open information (satellite images, topography, etc) it is pretty straightforward to reconstruct real places and to present geographical information. Just an example:
Polaritons are versatile quasiparticles that could be at the core of new technologies, since polariton devices have been proposed, such as polariton lasers, optical gates, transistors, spin-based elements and integrated circuits. Yet, their propagation depends strongly on the geometry of the pathway laid for them. In a recent paper, Luis Viña, Dolores Martín, et al. […]
