Накратко на български

Връзката между хиралноста на молекулите (тези, които не съвпадат с огледалния си образ) и спина на електроните е основният обект на изследване. Разбирането на този ефект помага за задълбочаване на познанията по химия и физика чрез обучение на млади специалисти.

Chiral-Induced Spin Selectivity Effect

The CISSE doctoral network puts together young scientists intrigued by the Chiral-Induced Spin Selectivity (CISS) effect that is the intimate link between the chirality of molecules and the spin of electrons. Chirality is a property of objects and molecules that cannot be superimposed on their mirror image. The spin that is the angular momentum of electrons, is an intrinsic property of elementary particles, like the mass and the electric charge are. The interplay between chirality and spin is an ideal field to train doctoral candidates (DCs) by exposing them to fresh views on pivotal chemical concepts. The CISSE objectives are twofold. On the one hand, the CISSE network seeks to make a giant leap forward into the knowledge and understanding of the intriguing CISS effect. On the other hand, CISSE delivers the finest quality research training and transfer of knowledge to ten DCs in an interdisciplinary, inter-sectoral, and revolutionary research field.

Цел на проекта

Chirality is often considered as a structural properties of molecules, but the concept also applies to elementary particles having a non-zero spin, i.e. electrons at rest are achiral but they acquire a helicity (chirality) in the direction of motion. Consequently, electrons are filtered according to their spin when crossing chiral materials. This newly uncovered chiral-induced spin selectivity (CISS) effect is surprisingly large. Spin polarization up to 100% has been demonstrated paving the way to multiple applications in chemistry, such as improved control of enantioselective reactions and easier separation of enantiomers. Impacts are also expected in physics (spintronics) and biology (molecular recognition of biomolecules, origin of bio-homo-chirality, magnetic compass of migratory songbirds). CISS effect is theoretically ill-defined. Sound structure-property relationship lacks also for the link between molecule chirality and CISS effect magnitude. CISSE proposal intends to contribute to a giant leap forward in the knowledge of CISS effect by putting together some of the best European, American and Israeli experts of the field, who will work towards its fundamental understanding. To this end, members of the CISSE consortium have been selected for their expertise and complementarities encompassing: synthetic chemistry, electrochemistry, surface science, bio-physical chemistry, quantum chemistry, nanoscience, industrial processes, analytical chemistry, and scientific instrument developments. Importantly, some beneficiaries have filled the first patent applications on CISS effect and have started to valorize them. Considerable scope for new discoveries and invention remains because the field of CISS effect is still in its infancy. The topic is particularly suited to educate ESRs because of its novelty and potential. To gain a different perspective on their research activities, ESRs will also contribute to an artistic creation highlighting spin and chirality.
