Amalensi okuxhumana okubona ebusuku angenzeka ngegraphene

Inzwa entsha yokukhanya ingadala ukubona okungenamkhawulo

Ubuchwepheshe bokubona ebusuku buya ngokuya buthuthuka, kusukela kuzibuko ezinkulu zombono wasebusuku ezidayiswa ku-eBay kuya ezingilazini zokushayela ezibonwa kahle ebusuku. Manje, sibonga u-Zhaohui Zhong Umsizi Woprofesa Wezobunjiniyela Bakagesi Nekhompyutha eNyuvesi yaseMichigan kanye nethimba lakhe labacwaningi, i-lens yokuxhumana yombono wasebusuku ingenzeka.

NgokukaDante D’Orazio waseThe Verge, onjiniyela bakagesi eNyuvesi yaseMichigan bathola indlela yokusebenzisa i-graphene (izingqimba ezimbili zekhabhoni enogqinsi lwe-athomu) ukuzwa ukukhanya kwe-infrared. U-Allen McDuffee ovela ku-Wired.com uthi ithimba lika-Zhong linike amandla idizayini yamalensi okuxhumana okubona ebusuku ngokubeka “ungqimba oluvikelayo phakathi kwezendlalelo ezimbili ze-graphene [nezela] amandla kagesi. Lapho ukukhanya kwe-infrared kushaya umkhiqizo owenziwe ngezingqimba, ukusabela kwawo kukagesi kukhuliswa kuqine ngokwanele ukuze kuguqulwe kube isithombe esibonakalayo.”

UDouglas Cobb ovela ku-Guardian Liberty Voice uthi nakuba i-graphene ibikade isetshenziswa kumalensi okuxhumana ukuzama ukunika amandla ukubona ebusuku, imizamo enjalo ayiphumelelanga ngenxa yokungakwazi kwe-graphene ukusabela ezindaweni ezihlukile ze-spectrum yokukhanya. Kodwa-ke, uthi u-Zhong nethimba lakhe labacwaningi balunqoba lolu daba ngokwakha “isangweji lezendlalelo ... umgoqo ovikelayo phakathi kwezingcezu ezimbili ezizacile kakhulu ze-graphene, futhi amandla kagesi azothunyelwa ngongqimba olungezansi.”

UCobb uthi ngokusho kukaZhong, idizayini izoba mncane, ngaleyo ndlela ikwazi “ukupakishwa kwilensi yokuxhumana noma ihlanganiswe nomakhalekhukhwini.”

Ukutholwa kwamandla obuchwepheshe be-graphene akugcini nje ngokuvula indlela yamalensi okuxhumana okubuka ebusuku kodwa nokunye okusunguliwe okungaba khona. NgokukaCobb, uZhong uthe odokotela bangasebenzisa i-graphene ukuqapha ukugeleza kwegazi lesiguli ngaphandle kokuthi banyakaze noma basithwetshulwe.
