GRAPHENE, MAI SIFFOFIN MULKI
Graphene sabon abu ne wanda zai canza abin da muke amfani da tufafi.
An ambata a baya a cikin labarinmu akan sababbin yadudduka, graphene yana ci gaba da haifar da damuwa. Kuma da kyakkyawan dalili. Masu binciken biyu daga Jami'ar Manchester, André Geim da Konstantin Novoselov sun gano a 2004, kuma sun ba da lambar yabo ta Nobel a fannin kimiyyar lissafi a shekarar 2010, wannan sabon abu da ba a taba gani ba yana da tarin fasaloli na musamman.
Theaukar sifa iri ɗaya na ƙwayoyin carbon waɗanda aka tsara a cikin tsarin saƙar zuma, graphene ya zo cikin tsarkakakken tsari, ba tare da ƙari ko sunadarai ba. An tsara shi a cikin zanen gado, wanda ya dace da shimfidar wuta da wutar lantarki ya sanya shi zama ɗan takara mafi dacewa don haɗa kayan masaku, ban da amfanin muhalli, kamar yadda graphene ke shan hydrocarbons da kayan aikin ƙasa.
Graphene za a iya bayyana shi azaman ɗari mai ɗari na zafin hoto. Itace asalin tsarin sauran alloli, gami da hoto, gawayi, carbon nanotubes da fullerenes. Hakanan za'a iya ɗaukar shi azaman babban ƙamshin ƙwaya mai ƙarancin gaske, batun iyakance na dangin hydrocarbons na polycyclic mai ƙamshi. Binciken Graphene ya fadada da sauri tun lokacin da aka fara rarrabe kayan a 2004. An sanar da bincike ne ta hanyar bayanin tsinkayen abun da graphene ya kirkira, tsari da kaddarorin sa, wadanda duk an kirga su shekarun da suka gabata. Kyakkyawan ɗan ƙaramin jaka kuma ya zama abin mamaki mai sauƙin keɓewa, yana mai yiwuwa yin ƙarin bincike. Andre Geim da Konstantin Novoselov a jami'ar Manchester sun sami lambar yabo ta Nobel a fannin kimiyyar lissafi a shekara ta 2010 "saboda gagarumin gwaje-gwajen da aka yi game da sinadarin graphene mai nauyin biyu.
An samo yadudduka da aka lakafta ta hanyar rage sinadarai na graphene oxide. An samo yadudduka masu gudanar da aikace-aikace da shafawa da yawa na graphene. Electrochemical impedance spectroscopy ya nuna halin kirkirar yadudduka. Matsakaicin sikanin shine maɓallin maɓallin keɓaɓɓu a cikin halayyar voltammetry na cyclic. Binciken microscopy na lantarki yana nuna karuwar wutar lantarki.
