Ngemuva kwesikhathi eside sokucwaninga, kwenziwa izifundo kanye nezinye izindaba eziyinkulungwane, kubonakala sengathi ekugcineni yilowo obhapathizwe ngumphakathi wesayensi njengo laser enamandla ngokwengeziwe wezwe ekugcineni sekuqalile ukusebenza. Njengokulangazelela ukukutshela lokho, indawo ekuyo idolobha laseJalimane i IHamburg Ngakho-ke, okungenani kulokhu, ayikaze iye kwezinye izindawo ezifana ne-United States, China noma Japan, izindawo ezibonakala zamuva nje zithambekele kakhulu kulolu hlobo lokuvulwa.
Uma singena emininingwaneni ethe xaxa, kufanele sikhumbule ukuthi uma sivakashela le ndawo, okokuqala, ngeke sikwazi ukufinyelela kule laser ekhethekile futhi, okwesibili, ngeke sikwazi ngisho nokubona izakhiwo njengoba zitholakala indawo engaphansi komhlaba ukuze 38 amamitha ukujula, indawo lapho iqembu lochwepheshe lakha khona umhubhe cishe 3,4 amakhilomitha ubude. Izinhlangano ezivela emazweni afinyelela kwayishumi nanye ezehlukene zibambe iqhaza ekwakhiweni kwalesi sikhungo.
I-laser enamandla kakhulu eyenziwe ngabantu emhlabeni kuze kube yimanje ikhishwe i-European XFEL
Ngokuqondene nezici ezenza le laser ihluke, ikutshele ukuthi sibhekene ne- i-electron laser yamahhala noma, ngegama layo ngesiNgisi, i-X-ray Free Electron Laser (XFEL). Lolu bekunguhlobo olukhethwe ngoba, ukuze lusebenze, isebenzisa ama-electron asheshayo akhululekile engaboshiwe kwi-athomu. La ma-elektroni ahamba ngamandla kazibuthe, into ebangela wona yabelana ngezinto ezibonakalayo zama-lasers ajwayelekile yize ziqala kusuka kumgomo ohluke ngokuphelele womzimba.
Ukuze le laser isebenze abaklami bayo kuye kwadingeka bakhe i-accelerator eqondile yokulinganisa cishe Amamitha angu-1609 okubuye kubhalwe ukuthi yiyona enkulu kunazo zonke emhlabeni eyakhiwe kuze kube manje. Lolu hlelo luyakwazi ukukhiqiza ifayela le- I-X-ray enobude bamaza ama-nanometer ayi-0 kuphela, ekhishwa isampula lapho ucwaningo luzokwenziwa khona ukuze igagasi eliwumphumela elibuyela emuva lapho lishaya isampula liqoqwe ngochungechunge lwemitshina etholakala nxazonke zalo. Ngenxa yalokhu, izithombe ziyatholakala.
I-laser eyingqayizivele yokuqhubekela phambili ocwaningweni lwesayensi
Le laser iyakwazi khiqiza kufika ku-27.000 pulses ngomzuzwana okusho ukuthi sikhuluma cishe izikhathi ezingama-200 ngaphezu kwamanye ama-lasers. Le mpahla iyivumela ukuthi isebenze sengathi iyikhamera enejubane elikhulu, okuyi Iyakwazi ukuthwebula izithombe zama-athomu angawodwa kwisigidi esisodwa sesekhondi. Ngenxa yalokhu, ososayensi, futhi kulapho inhloso yangempela ngokwakhiwa kwalolu hlelo lwe-laser, izokwazi ukutadisha izinto ezincane njengamagciwane namaseli ngokuningiliziwe ukuze kamuva zilinganise ukutholwa kwazo ukuze zilingane nosayizi yamaplanethi nezinkanyezi.
Phakathi kososayensi bokuqala abazoba nethuba lokukwazi ukusebenza ngale laser, gqamisa iqembu lase-University of Oxford eliholwa yi UJustin wark, okuzozama ukuxazulula imibuzo ethile engaziwa okwamanje mayelana nendawo yoMhlaba uqobo. Ngakolunye uhlangothi sinabacwaningi abavela Allen orvile abahlose, ngosizo lwaleli thuluzi elisha, ukuqonda imishini yamangqamuzana ama-enzyme ukuze ikwazi ukukhiqiza ama-antibiotic ngenxa yokukwazi ukubona ngokuningiliziwe amaphethini wokuphendula ayinkimbinkimbi avela kuwo.
Lokhu kumane nje kuyingxenye yamaqembu abacwaningi asebevele benentshisekelo ekusetshenzisweni kwale laser futhi, esikhathini esifushane kakhulu, abazoqala ukusebenza besebenzisa lokho okubizwa ngokuthi yi-laser enamandla kunayo yonke emhlabeni, ngokufanayo njengoba kulindelwe, esikhathini esimaphakathi nesikhathi eside, limelela inqubekela phambili ephawulekayo emikhakheni eyinkimbinkimbi njenge imithi ngisho naku ukuthuthukiswa kwezinto ezintsha.
