Researchers analyze the directional "picoantenna-like" behavior of tunnel junctions formed by surface defects at the atomic scale
News Researchers analyze the directional peak-antenna-like behavior of tunnel junctions formed by surface defects at the atomic scale The profile of light collected with tunneling microscopes changes when the tip is placed on an atomic step. This phenomenon can be exploited to build picoantennas, nanoscale elements that direct light.

Chemistry researchers develop a protein capable of eliminating microplastics
From November 13 to 19, the third Global Plastics Treaty Meeting was held in Nairobi (Kenya), which tried, albeit in vain, to find an agreement to hold "countries and companies accountable for their action, or inaction, on plastic pollution and its impact on our health, environment and economy". World leaders have set themselves a date to further discuss the issue in April 2024 in Ottawa, Canada, but in the meantime, plastics and microplastics continue to produce pollution, primarily in waters around the globe.

First X-ray fluorescence chemical analysis of Pompeii Casts confirms death by suffocation
An international research team led by the University of Valencia, in which the University of Cambridge and the Italian Ministry of Culture participate, has analysed for the first time the bones of the Pompeii Casts (the skeletons of its inhabitants in a plaster mould) with an innovative technique, x-ray fluorescence analysis, and concludes that they died of suffocation, not burned or dehydrated as other theories defend.

New method for "capturing" changes in chemical bonds due to electronic dynamics
An international collaboration involving the Autonomous University of Madrid (UAM) has succeeded in bringing X-ray photoelectron spectroscopy to the femtosecond time scale. This advance, published in Nature Communications , will not only make it possible to investigate the effects on chemical bonds due to the movements of atomic nuclei, but also those caused by electronic dynamics.

The first analysis of zinc in dental enamel in a Neanderthal indicates that he had a very meat-rich diet
The first analysis of zinc in dental enamel in a Neanderthal indicates that he had a very meat-rich diet
Domingo Carlos Salazar, molecular archaeologist and researcher at the University of Valencia, has participated in the first analysis of zinc isotope ratios (atoms of different masses of the same chemical element) in the dental enamel of a Neanderthal to determine his position in the food chain. The study, published in the journal PNAS, and led by a researcher from the National Centre for Scientific Research (CNRS) in France, has determined that the Neanderthal to which the tooth belonged probably had an almost carnivorous diet.

New mechanism to transfer chirality between molecules in the nanoscale field
New mechanism to transfer chirality between molecules in the nanoscale field
If we compare the right to the left hand, we can see these are specular images —that is, like symmetrical shapes reflected in a mirror— and they cannot superimpose on each other. This property is chirality, a feature of the matter that plays with the symmetry of biological structures at different scales, from the DNA molecule to the tissues of the heart muscle.
