Iwumthombo waphakade wamandla wamahhala. Ukunyakaza okushisayo kwe-graphene kuguqulwa kube ugesi

Ososayensi baseNyuvesi yase-Arkansas benze uhlelo olungaphehla ugesi ngokunyakazisa okushisayo kwe-graphene. Ijeneretha yamandla eyakhelwe phezu kwesisekelo sayo inethuba lokusebenza isikhathi eside konke lokhu kuzoba isikhathi esingakanani ekushiseni okuvamile - okungenani lena inkolelo-mbono eyakhiwe eminyakeni emithathu edlule.

I-Graphene energy generator. Mhlawumbe hhayi imishini, kodwa microsensors - yebo. Esikhathini esizayo

I-graphene "ishidi" lama-athomu ekhabhoni axhunywe ngamabhondi angawodwa nakabili. Ama-athomu ahlelwe ngama-hexagon futhi akha isakhiwo esiyisicaba i-athomu eyodwa ewugqinsi, okunikeza i-graphene inani lezinto ezimangalisayo. Enye yazo ukunyakaza okushisayo okubangela imibimbi nokukhubazeka eshidini le-graphene.

I-graphene ngaphansi kwesibonakhulu se-electron TEAM 0.5 ethuthukiswe iqembu lase-University of California, e-Berkeley. Ama-vertices aphuzi ama-athomu ekhabhoni, izimbobo ezimnyama zingaphakathi kwamaheksagoni. Uma ucabanga ukuthi okumnyama kukhomba kwesokunxele, linda imizuzwana embalwa, zama ukulandelela umugqa wekhabhoni ophuzi onqenqemeni olungakwesokudla, noma ulayishe isithombe kusihleli sesithombe bese usizungezisa ngokushesha amadigri angu-90-180. Ku-IrfanView, lokhu kungenziwa ngokucindezela inkinobho ethi R(c) NCEM, University of California, Berkeley.

Ososayensi baseNyuvesi yase-Arkansas banyathelisa inkolelo-mbono eminyakeni emithathu edlule eyabonisa ukuthi ukushintsha ukuma kwe-graphene kungasetshenziswa ukukhiqiza amandla. Lokhu kwakungqubuzana nezibalo zika-Richard Feynman, kodwa kwavela ukuthi i-graphene emazingeni okushisa asekamelweni ingakhiqiza amandla ashintshashintshayo.

I-graphene eyawohloka kancane yadala i-low-frequency alternating current, futhi uhlelo olwakhiwe ososayensi lwayiguqulela ekubeni i-pulsating direct current (DC) futhi yawukhulisa ngokwengeziwe (umthombo). Lokhu kubalulekile ngoba ama-electronics asebenza kahle kakhulu kumafrikhwensi aphansi.

Mhlawumbe okuphikisana kakhulu nalokho ukuthi i-resistor esetshenziswe ohlelweni ayizange ishise ngesikhathi sokusebenza. Njengoba amandla avela ekuguquleni ukunyakaza okushisayo kube ugesi, ibhalansi yagcinwa. Uma ugesi uphela, i-resistor kufanele iphole.

Ngemuva kokwakha umdwebo owenziwe ngomumo ofakazela ukuthi ithiyori isebenza ngokusebenza (PoC), Ososayensi manje basebenzela ukuthi kungenzeka ukugcina amandla akhiqizwa ohlelweni ku-capacitor. Njengakupopayi ongezansi (okuluhlaza - ukukhokhiswa okunegethivu, okubomvu - izimbobo, amashaji avumayo):

Isinyathelo esilandelayo ukuwenza ube mncane konke futhi wakhe phezu kwe-silicon wafer. Uma iphumelela, futhi uma kungenzeka ukuhlanganisa izimiso ezinjalo eziyisigidi ku-microcircuit eyodwa, ingasebenza njengejeneretha kagesi engenakufa.
