Attosecond pulseszivisa zvakavanzika zvekunonoka nguva
Masayendisiti muUnited States, nerubatsiro rweAttemocond Pulses, vakaratidza ruzivo rutsva nezvePhotowelectric Estress: thefotolectric emissionkunonoka kuri kusvika pamakumi manomwe ematteseconds, zvakanyanya kureba kupfuura zvaimbotarisirwa. Izvi zvinopesana nekutsvaga matambudziko aripo emhando dzekuripo uye zvinopa kunzwisisika kwakadzama kwekudyidzana pakati peaine magetsi, zvichitungamira mukuvandudza matekinoroji akadai semamirioni uye maseru eSolar.
Iyo phyelectric mhedzisiro inoreva nezve chiitiko icho kana mwenje uchipenya pane molecule kana atomu pane simbi pamusoro, iyo photon inofambidzana nemamolekhodhi kana kuAtomu uye inoburitsa maelekitori. Izvi zvinoitwa hazvisi zveimwe chete pane zvakakosha nheyo dzehuwandu hwehuwandu hwehuwandu, asi zvakare zvine simba rakakura pane dzazvino fizikisi, chemistry uye zvigadzirwa sainzi. Nekudaro, mumunda uyu, inonzi Fodya Dreay Nguva yave iri nyaya inokakavara, uye mhando dzakasiyana dzemhando dzakazvitsanangura kumadhigirii akasiyana, asi hapana kubvumirana kwakabatana kwakaumbwa.
Sezvo munda wetsiva weAttemocond yakawedzera zvinoshamisa mumakore achangopfuura, chishandiso ichi chinobuda chinopa nzira isina kumboitika yekuongorora nyika yemiumbi. Nezviitiko chaizvo nezviitiko zvinoitika pane zvakanyanyisa nguva pfupi zviyero, vaongorori vanokwanisa kuwana rumwe ruzivo nezve maitiro ane simba ezvikamu. Muchangobva kudzidza, vakashandisa nhevedzano yakakwirira-ray pulses yakagadzirwa neyakaenderana neyakaenzana
Kuwedzera kuongorora iyo trajectories yeaya emagetsi emagetsi, ivo vakashandisa mumwe nemumwe vachifaralaser purseskuyera nguva dzemaoko emagetsi mune dzakasiyana nzira. Iyi nzira yakavatendera kuti vaongororezve mutsauko wakakosha pakati pezvakawanda zvekutaurirana zvinokonzerwa nekudyidzana pakati peaine maelekitori, kusimbisa kuti kunonoka kunogona kusvika mazana manomwe ematteseconds. Zvakakosha kuziva kuti iyi kuwanikwa hakusi kungosimbisa mamwe mimwe hypotheses, asi zvakare inomutsa mibvunzo mitsva, kuita dzidziso dzakakodzera dzinofanira kuongororwa uye kugadziridzwa.
Uye zvakare, kudzidza kunoratidza kukosha kwekuyera nekududzira nguva ino kunonoka, izvo zvakanyatsonzwisisa mibairo yekuedza. MuProtein Crystallography, uye zvimwe zvekufungidzira zvinosanganisira kuwirirana kweX-rays zvine basa, iyi data ichave chikonzero chakakosha chekugadzirisa nzira dzehunyanzvi uye kugadzirisa miitiro yekufungidzira. Naizvozvo, timu inoronga kuenderera mberi nekuongorora masimba emhando dzakasiyana dzemanyorerwo emamolecules
