Cunoscute sub numele de cadre metal-organice (MOF), aceste structuri extrem de poroase pot capta gaze, recolta ap\u0103 \u0219i stoca molecule cu o eficien\u021b\u0103 f\u0103r\u0103 precedent.<\/p>\n

Yaghi, profesor la Universitatea Berkeley din California, a \u00eemp\u0103r\u021bit Premiul Nobel pentru Chimie \u00een 2025 pentru pionieratul \u00een chimia reticular\u0103, o metod\u0103 de proiectare a materialelor molecul\u0103 cu molecul\u0103.<\/p>\n

El crede c\u0103 MOF-urile \u0219i rudele lor, cadrele organice covalente (COF), ar putea defini urm\u0103toarea er\u0103 tehnologic\u0103 de dup\u0103 siliciu.<\/p>\n

De la design molecular la materiale revolu\u021bionare<\/h2>\n

Yaghi a \u00eenceput s\u0103 lucreze la MOF-uri \u00een anii \u201990 ca pe o provocare pur intelectual\u0103.<\/p>\n

La acea vreme, mul\u021bi chimi\u0219ti considerau imposibil\u0103 proiectarea unor materiale cristaline cu structuri precise \u0219i repetitive.<\/p>\n

Natura, p\u00e2n\u0103 la urm\u0103, favorizeaz\u0103 dezordinea, nu arhitectura molecular\u0103 construit\u0103 dup\u0103 specifica\u021bii.<\/p>\n

Aceast\u0103 presupunere s-a schimbat \u00een 1999, c\u00e2nd echipa lui Yaghi a sintetizat MOF-5, un material pe baz\u0103 de zinc cu o porozitate extrem\u0103.<\/p>\n

Doar c\u00e2teva grame aveau o suprafa\u021b\u0103 intern\u0103 comparabil\u0103 cu cea a unui teren de fotbal.<\/p>\n

Descoperirea a demonstrat c\u0103 materialele ordonate \u0219i foarte poroase pot fi create inten\u021bionat \u0219i \u00een mod fiabil.<\/p>\n

Aplica\u021bii practice: ap\u0103, carbon \u0219i tehnologii curate<\/h2>\n

Structura unic\u0103 a MOF-urilor le permite s\u0103 re\u021bin\u0103 molecule specifice \u00een interiorul porilor.<\/p>\n

Potrivit lui Yaghi, acest lucru le face ideale pentru extragerea apei din aer uscat, chiar \u0219i \u00een medii de\u0219ertice, precum \u0219i pentru captarea dioxidului de carbon direct din atmosfer\u0103.<\/p>\n

Startup-ul s\u0103u, Atoco, dezvolt\u0103 tehnologii bazate pe MOF-uri \u0219i COF-uri pentru uz industrial \u0219i reziden\u021bial.<\/p>\n

Un material, COF-999, a demonstrat performan\u021be solide \u00een cicluri repetate de captare a carbonului.<\/p>\n

Alte sisteme pot recolta mii de litri de ap\u0103 pe zi folosind lumina solar\u0103 ambiental\u0103.<\/p>\n

Avantaje de sustenabilitate \u0219i eficien\u021b\u0103 energetic\u0103<\/h2>\n

Yaghi subliniaz\u0103 c\u0103 materialele reticulare pot fi proiectate av\u00e2nd \u00een vedere sustenabilitatea.<\/p>\n

Dispozitivele bazate pe MOF-uri pot fi demontate \u00een siguran\u021b\u0103 la finalul ciclului de via\u021b\u0103, evit\u00e2nd contaminarea pe termen lung a mediului.<\/p>\n

De asemenea, pot func\u021biona folosind c\u0103ldur\u0103 rezidual\u0103 sau energie solar\u0103, fiind mai eficiente energetic dec\u00e2t multe alternative existente.<\/p>\n

De\u0219i persist\u0103 provoc\u0103ri legate de produc\u021bia la scar\u0103 larg\u0103 \u0219i stabilitatea pe termen lung, Yaghi spune c\u0103 progresul se accelereaz\u0103.<\/p>\n

Instrumentele de inteligen\u021b\u0103 artificial\u0103 ajut\u0103 acum laboratorul s\u0103u s\u0103 optimizeze designul materialelor mai rapid ca niciodat\u0103.<\/p>\n

O nou\u0103 frontier\u0103 \u0219tiin\u021bific\u0103<\/h2>\n

Yaghi sus\u021bine c\u0103 chimia reticular\u0103 reprezint\u0103 o schimbare profund\u0103 \u00een modul \u00een care func\u021bioneaz\u0103 \u0219tiin\u021ba materialelor.<\/p>\n

\u00cen loc s\u0103 descopere materiale \u00eent\u00e2mpl\u0103tor, oamenii de \u0219tiin\u021b\u0103 le pot proiecta acum pentru nevoi sociale specifice.<\/p>\n

De la cataliz\u0103 \u0219i dezvoltarea de medicamente p\u00e2n\u0103 la ap\u0103 curat\u0103 \u0219i solu\u021bii climatice, MOF-urile \u0219i COF-urile ar putea juca un rol central \u00een tehnologiile viitorului.<\/p>\n

El consider\u0103 c\u0103 domeniul se afl\u0103 abia la \u00eenceputul poten\u021bialului s\u0103u, descriind momentul actual drept o revolu\u021bie \u0219tiin\u021bific\u0103 t\u0103cut\u0103, dar profund\u0103.<\/p>\n","protected":false},"excerpt":{"rendered":"
