OrigiA new experiment has characterised the properties of the electrons emitted when a key constituent of DNA is bombarded with high-velocity ions.
When fast-moving ions cross paths with large biomolecules, the resulting collisions produce many low-energy electrons which can go on to ionise the molecules even further. To fully understand how biological structures are affected by this radiation, it is important for physicists to measure how electrons are scattered during collisions. So far, however, researchers’ understanding of the process has remained limited. In new research published in EPJ D, researchers in India and Argentina, led by Lokesh Tribedi at the Tata Institute of Fundamental Research, have successfully determined the characteristics of electron emission when high-velocity ions collide with adenine – one of the four key nucleobases of DNA.

Through fresh analysis of a method first proposed by Alan Turing to explain the diversity of natural patterns, a team of researchers offer new explanations of how living systems can order themselves on large scales.
In 1952, Alan Turing published a study which described mathematically how systems composed of many living organisms can form rich and diverse arrays of orderly patterns. He proposed that this ‘self-organisation’ arises from instabilities in un-patterned systems, which can form as different species jostle for space and resources. So far, however, researchers have struggled to reproduce Turing patterns in laboratory conditions, raising serious doubts about its applicability. In a new study published in EPJ B, researchers led by Malbor Asllani at the University of Limerick, Ireland, have revisited Turing’s theory to prove mathematically how instabilities can occur through simple reactions, and in widely varied environmental conditions.

The Special Issue contains the articles which were presented at the International research and practice conference “Nanotechnology and Nanomaterials” (NANO-2018), which was organized by the Institute of Physics of NAS of Ukraine with the participation of the Yuriy Fedkovych Chernivtsi National University (Ukraine), University of Tartu (Estonia), University of Turin (Italy), Pierre and Marie Curie University – Paris 6 (France).
The Special Issue gathered high-level articles at the forefront of nanoscience research which is devoted to: the optical absorption by a nanosystem with dielectric quantum dots; the fabrication of crystalline Bi2TeO5 - Bi4Si3O12 - SiO2 nanocomposite; the existence of both size and “even-odd” effects for the lifetime of carbyne-based nanodevices consisting of two graphene sheets connected by a carbyne chain; the adsorption properties of the silica-titanium mixed oxide; the adsorption properties and application perspectives of BSA films as sensitive coatings for gas sensors; the properties of MgFe2O4; to the problem of band broadening of SPR; the structural studies concerning the formation of self-assembled indium deposited nanostructures on the (100) surface of In4Se3 layered semiconductor and the possibility of constructing the general dynamic properties of a conduction electron injected into graphene in the rectangular lattice approximation.
The Guest Editor, Olena Fesenko, hopes that this collection provides a quick overview on recent trends in this emerging field of research.
