Dr. Dumitru-Claudiu SERGENTU, Asistent de Cercetare \u0218tiin\u021bific\u0103 al Universit\u0103\u021bii \u201eAlexandru Ioan Cuza\u201d din Ia\u0219i, \u00een cadrul Laboratorului de investigare a proceselor fizico-chimice din faz\u0103 gazoas\u0103 cu implica\u0163ii \u00een formarea aerosolilor organici secundari, RA-03 RECENT-AIR, a realizat un studiu, \u00een colaborare cu o echip\u0103 pluridisciplinar\u0103 de cercet\u0103tori din Statele Unite ale Americii \u0219i China, privind sinteza \u0219i caracterizarea unor noi compu\u0219i ce stabilizeaz\u0103 leg\u0103turi chimice multiple \u00eentre un atom de uraniu \u0219i unul de azot, care a fost publicat \u00een prestigioasa revist\u0103 Nature Communications, \u00een data de 23 noiembrie 2022.<\/p>\n

\u201eRelevan\u021ba acestui studiu este sus\u021binut\u0103 la un nivel mai general de problematica proces\u0103rii de\u0219eurilor nucleare la nivel global, ce atrage dup\u0103 sine nevoia de a cunoa\u0219te c\u00e2t mai precis comportamentul fizico-chimic al actinidelor.<\/p>\n

Actinidele sunt elemente metalice radioactive cu aplica\u021bii, \u00een principal, \u00een industria nuclear\u0103, acestea fiind extrem de nocive vie\u021bii odat\u0103 intrate \u00een contact necontrolat cu mediul \u00eenconjur\u0103tor (sol, ap\u0103 sau atmosfer\u0103).<\/p>\n

Astfel, dintr-o perspectiv\u0103 \u0219tiin\u021bific\u0103, cercet\u0103torii din cele mai mari laboratoare ale lumii \u00ee\u015fi unesc eforturile pentru a se ajunge la un consens cu privire la capacitatea actinidelor de a forma leg\u0103turi chimice cu alte molecule \u0219i de a le caracteriza pe acestea. Articolul, intitulat \u201cA charged diatomic triple-bonded U\u2261N species trapped in C82 fullerene cages\u201d,descrie leg\u0103tura covalent\u0103 tripl\u0103 dintre un atom de uraniu \u0219i unul de azot ce se formeaz\u0103 \u00een interiorul unor fulerene. Astfel de compu\u0219i chimici sunt foarte rari \u00een literatura de specialitate\u201d, a declarat ACS. Dr. Dumitru-Claudiu SERGENTU.<\/p>\n

Dr. Dumitru-Claudiu SERGENTU a absolvit Facultatea de Chimie a Universit\u0103\u021bii \u201eAlexandru Ioan Cuza\u201d din Ia\u0219i \u00een anul 2011, a absolvit un master European \u00een Chimie teoretic\u0103 \u0219i modelare computa\u021bional\u0103 \u00een cadrul Universit\u0103\u021bii din Groningen(\u021a\u0103rile de Jos) \u0219i a ob\u021binut titlul de doctor \u00een Chimie la Universitatea din Nantes, Fran\u021ba. P\u00e2n\u0103 la sf\u00e2r\u0219itul anului 2021, Dr. Sergentu a efectuat studii de la Universitatea din Buffalo, New York (SUA), sub \u00eendrumarea Profesorului Jochen Autschbach. De asemenea, este autor a 31 de articole \u0219tiin\u021bifice publicate \u00een reviste de prestigiu la nivel mondial, precum Nature, Nature Communications sau Journal of The American Chemical Society.<\/p>\n
