Ukuguqulwa kwezinguquko embonini yamandla: Ososayensi bathuthukisa indlela entsha yokugcina amandla avuselelekayo

Eminyakeni yamuva nje, amandla avuselelekayo asephenduke enye indlela ethandwa kakhulu kumafutha anendabuko endabuko. Kodwa-ke, enye yezinselelo ezinkulu ezibhekene nomkhakha wamandla avuselelekayo bebelokhu ukuthola indlela yokugcina amandla anetheleleke akhiqizwe emithonjeni evuselelekayo efana nemithombo yomoya namandla elanga. Kepha manje, ososayensi baye bathola ukutholwa okuhlabayo okungashintsha konke.

Abaphenyi e-University of California, iBerkeley bathuthukise indlela entsha yokugcina amandla avuselelekayo abangaguqula imboni. Impumelelo ifaka ukusetshenziswa kohlobo lwe-molecule olubizwa nge- "photowitch," olungenza ukukhanya kwelanga futhi lugcine amandla alo kuze kube luyadingeka.

Ama-molecule we-photowitch akhiwa izingxenye ezimbili: isakhi esidinga ukukhanya kanye nengxenye yesitoreji. Lapho kuvezwa ukukhanya kwelanga, ama-molecule amunca amandla futhi ayigcine ngendlela ezinzile. Lapho amandla agciniwe adingeka, ama-molecule angadalwa ukuze akhulule amandla ngendlela yokushisa noma ukukhanya.

Izicelo ezingaba khona zalokhu kuphumelela zikhulu. Isibonelo, ingavumela imithombo yamandla evuselelekayo efana namandla elanga namandla omoya azosetshenziswa ngempumelelo, noma ngabe ilanga lingashintshi. Kungenza futhi ukuthi sikwazi ukugcina amandla amaningi akhiqizwe ngezikhathi ezifunwa kancane bese uyikhipha ngesikhathi sezici ezifunwayo, ukunciphisa isidingo sezitshalo ezibizayo nezemvelo.

Abaphenyi belekela lokhu kuphumelela bajabule ngomthelela wayo ongaba khona embonini yamandla. "Lokhu kungaba ngumguquki womdlalo," kusho omunye wabaphenyi abahola, uSolwazi Omar Yaghi. "Kungenza amandla avuselelekayo asebenze kakhulu futhi abizi kakhulu, futhi asisize siqhubekele esikhathini esizayo esimeme."

Vele, kunomsebenzi omningi okufanele wenziwe ngaphambi kokuthi lobu buchwepheshe bungasetshenziswa kabanzi. Abaphenyi njengamanje basebenzela ukwenza ngcono ukusebenza kahle kwama-molecule we-photowitch, kanye nokuthola izindlela zokukala ukukhiqizwa. Kepha uma ziphumelela, lokhu kungaba yindawo eguqukayo enkulu ekulweni nokushintshwa kwesimo sezulu kanye noshintsho lwethu lokuhlanza, ikusasa elizinzile.

Ekuphetheni, ukuthuthukiswa kwama-molecule we-photowitch amelela impumelelo enkulu embonini yamandla. Ngokuhlinzeka ngendlela entsha yokugcina amandla avuselelekayo, lobu buchwepheshe bungasisiza ukuba sisuke ekuthembeleni kwethu kumafutha emithali nasekupheleni okuzayo. Ngenkathi kukhona umsebenzi omningi okufanele wenziwe, lokhu kuphumelela kuyisinyathelo esijabulisayo phambili ekufuneni kwethu ukuhlanza, amandla ama-greener.
