As the top atomic monolayer lifts a few Å off the underlying bulk Au (111), ab initio electronic structure calculations show that for gaps >1.5 Å, visible light squeezes inside the empty slot underneath, giving optical field distributions 2 Å thick, less than the atomic diameter. Considerable attention has been paid in the past decades […]
Magnetic two-dimensional (2D) semiconductors have attracted a lot of attention because modern preparation techniques are capable of providing single crystal films of these materials with precise control of thickness down to the single-layer limit. It opens up a way to study a rich variety of electronic and magnetic phenomena with promising routes towards potential applications […]
Deep below the Spanish side of the Pyrenees, we find the LSC (Laboratorio Subterráneo de Canfranc – Canfranc Underground Laboratory), where the NEXT experiment is taking place. Its goal is one of the remaining holy grails of particle physics: the proof that the neutrino is its own antiparticle, a result with profound meaning not only […]
Mitochondria are the primary energy providers for cell activities. The quantification of the size and geometry of mitochondria is crucial to basic neuroscience research, as it contributes to the identification of neuron types. This quantification is also informative to clinical studies where energy-usage unbalances are implied, like bipolar disorder or diabetes. High-resolution imaging technologies like […]
There are numerous ongoing observational campaigns that will take on the wealth of information encoded in the clustering of matter in the universe. These observations will map the position and shapes of hundreds of millions of galaxies up to tens of thousands of square degrees. Although it will be crucial to keep statistical uncertainties and […]
A cement is any of various substances used for bonding or setting to a hard material. A popular one, Portland cement, is a mixture of calcium silicates and aluminates made by heating limestone (CaCO3) with clay (that contains aluminosilicates) in a kiln. The product is then ground to a fine powder. When Portland cement is […]
Friction, an everyday phenomenon, has perplexed scientists for centuries. Though extensively researched, our understanding remains fragmented, primarily due to the multifaceted interactions that span across varying scales. Achieving an accurate grasp of the precise contact conditions between objects has been a longstanding challenge, a feat recently made possible through advancements in scanning probe microscopy. Yet […]

Molecular vibrations couple to visible light only weakly, have small mutual interactions, and hence are often ignored for non-linear optics. Still, molecular vibrations dominate electronic, thermal, and spin transport in a wide range of devices from photovoltaics to molecular electronics as well as being of fundamental interest. Surface-Enhanced Raman Spectroscopy (SERS) is well-established for studying […]
Chemical contamination of water bodies on one hand, and water shortages due to overexploitation on the other, have increased the need for effective and efficient water treatment and decontamination processes. Two important aspects need to be taken into consideration to define what is an “effective and efficient” treatment. First, as current methods of removing pathogens […]
The scattering of conduction electrons in metals owing to impurities with magnetic moments is known as the Kondo effect, after Jun Kondo, who analysed the phenomenon in 1964. This scattering increases the electrical resistance and has the consequence that, in contrast to ordinary metals, the resistance reaches a minimum as the temperature is lowered and […]
