Inkqubela phambili yoShishino lwaMandla: Izazinzulu ziphuhlisa indlela entsha yokugcina amandla ahlaziyekayo

Kwiminyaka yakutshanje, amandla avuselelekayo abe yindlela ethandwayo kakhulu endaweni yamafutha emveli efosili. Nangona kunjalo, enye yeengxaki ezinkulu ezijongene neshishini lamandla avuselelekayo kukufumana indlela yokugcina amandla agqithisileyo aveliswa kwimithombo evuselelekayo efana nomoya kunye namandla elanga. Kodwa ngoku, izazinzulu zenze uvumbululo olumangalisayo olunokutshintsha yonke into.

Abaphandi kwiYunivesithi yaseCalifornia, eBerkeley baphuhlise indlela entsha yokugcina amandla avuselelekayo anokuguqula eli shishini. Olu phuhliso lubandakanya ukusetyenziswa kohlobo lwemolekyuli ebizwa ngokuba yi-"photoswitch," enokufunxa ukukhanya kwelanga kwaye igcine amandla ayo de ifuneke.

Iimolekyuli ze-photoswitch zenziwe ngamacandelo amabini: icandelo elifunxa ukukhanya kunye necandelo lokugcina. Xa zibekwe elangeni, iimolekyuli zifunxa amandla kwaye ziwagcine kwimo ezinzileyo. Xa kufuneka amandla agciniweyo, iimolekyuli zinokuqalwa ukuba zikhuphe amandla ngendlela yobushushu okanye ukukhanya.

Iindlela ezinokubakho zokusetyenziswa kolu phuhliso zinkulu kakhulu. Umzekelo, ingavumela imithombo yamandla avuselelekayo njengamandla elanga nawomoya ukuba asetyenziswe ngokufanelekileyo, nokuba ilanga alikhanyi okanye umoya awuvuthuzi. Ingenza kube nokwenzeka ukugcina amandla agqithisileyo aveliswayo ngamaxesha emfuno ephantsi uze uwakhulule ngexesha lemfuno ephezulu, nto leyo enciphisa isidingo sezityalo zamandla ezibizayo neziyonakalisa okusingqongileyo.

Abaphandi abasemva kolu phuhliso bavuya kakhulu ngempembelelo yalo kwishishini lamandla. “Oku kungatshintsha umdlalo,” utshilo omnye wabaphandi abaphambili, uNjingalwazi u-Omar Yaghi. “Kungenza amandla ahlaziyekayo abe luncedo ngakumbi kwaye angabizi kakhulu, kwaye kusincede siqhubekele phambili kwikamva elizinzileyo.”

Kakade ke, kusekho umsebenzi omninzi ekufuneka wenziwe ngaphambi kokuba obu buchwephesha busetyenziswe ngokubanzi. Abaphandi okwangoku basebenza ekuphuculeni ukusebenza kakuhle kweemolekyuli ze-photoswitch, kunye nokufumana iindlela zokwandisa imveliso. Kodwa ukuba bayaphumelela, oku kungaba yinguqu enkulu ekulweni notshintsho lwemozulu kunye notshintsho lwethu oluya kwikamva elicocekileyo nelizinzileyo.

Ukuqukumbela, uphuhliso lweemolekyuli ze-photoswitch lubonisa inkqubela phambili enkulu kushishino lwamandla. Ngokubonelela ngendlela entsha yokugcina amandla avuselelekayo, obu buchwephesha bungasinceda ukuba sisuke ekuxhomekekeni kwethu kumafutha efosili size siye kwikamva elizinzileyo. Nangona kusekho umsebenzi omninzi ekufuneka wenziwe, le nkqubela phambili linyathelo elinomdla eliya phambili ekufuneni kwethu amandla acocekileyo naluhlaza.
