Heterogeneous sorroundings are critical in the analysis of nerve ablation for treating chronic pains
Chronic pain is one of the most common problems of advanced age. Even though the combination of physical therapy and analgesics such as nonsteroidal anti-inflammatory drugs is effective in chronic pain treatments, it only confers short-term benefits. On the other […]
An additional contribution to the spin Hall effect induced by an electric current
The interactions between moving charges and magnetic fields can be quite complicated; more if we consider the quantum effects. One example is the collection of Hall effects.
Imagine that we have a conductor or a semiconductor through which a current […]
Huisgenases, new protein catalysts which are not enzymes
Proteins can perform a huge number of biological functions with amazing efficiency. In order to achieve these different functions, proteins rely on the precise 3D arrangement of functional groups which are referred to as the protein fold. Some of these […]
T cells could be key for early Alzheimer’s detection
For a long time Alzheimer disease has been studied mostly as a neuronal disease. However, recently the role of the immune system is getting more attention and its involvement more clear. Recent research has shown that a subpopulation of […]
Quantum atomic fluctuations stabilize the crystal responsible for superconductivity at 250 K
Achieving room temperature superconductivity is among the most pursued but elusive goals of scientists. In December 2014 researchers claimed to have observed superconductivity as high as 200 K in hydrogen sulfide at high pressure, breaking all the records thus […]
A local quantum emitter can be used to sense the environment of a molecule with the minimal quantum of energy
Plasmonic nanostructures confine light to dimensions far smaller than the free-space wavelength, as they mix optical fields with electronic excitations. It was not until the 1990s, with the appearance of accurate and reliable nanofabrication techniques, that plasmonics blossomed. It […]
An algorithm to discern sentiment in a text
Finding patterns in a text could be very useful. It could reveal if the text has been written by a certain person or not, for example. Going a step further, finding sentiments in a text or a speech can also […]
Matter manipulation with terahertz radiation
Terahertz (THz) radiation is all around us. For example, this page emits blackbody radiation mainly in the THz region (defined here from 0.3 THz to 30 THz). Because terahertz radiation begins at a wavelength of around one millimeter and proceeds […]
The limits of high speed rail
Author: Iván Rivera works as an engineer in innovation projects for railroads
Twelve years have passed since the world record for rail speed was set. “Operation V150”, which got its name from the target speed for its testbed trainset, 150 […]
Leaf-based microreactors for organic synthesis
Author: Daniel González-Muñoz is a predoctoral researcher in photocatalytic processes at Universidad Autónoma de Madrid.
Environmental problems and energy resources make it vitally important for the chemical industry to develop more sustainable and less polluting processes. Therefore, using solar energy […]
