"Black nitrogen" tare da graphene tsammanin halitta a cikin dakin gwaje-gwaje

A yau muna shaida yadda masana kimiyya ke ƙoƙarin aiwatar da kyawawan kaddarorin graphene ɗin da aka haɗa kwanan nan. An dai yi alƙawarin makamancin haka hada a cikin dakin gwaje-gwaje, wani abu mai tushen nitrogen wanda kaddarorinsa ke nuna yiwuwar babban aiki ko yawan ajiyar makamashi.

Kungiyar masana kimiyya ta kasa da kasa ce ta gano hakan a jami'ar Bayreuth da ke Jamus. Dangane da ka'idodin sunadarai da kimiyyar lissafi, sinadari ɗaya na iya wanzuwa ta nau'in abubuwa masu sauƙi daban-daban. Misali, ana iya juyar da iskar oxygen (O2) zuwa ozone (O3), da carbon zuwa graphite ko lu'u-lu'u. Irin waɗannan nau'ikan wanzuwar nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau’in nau’in nau’in nau’in halitta iri daya ake kira allotropes. Matsalolin nitrogen shine cewa akwai kaɗan daga cikin allotropes - kusan 15, kuma kawai uku daga cikinsu sune gyare-gyaren polymer. Amma yanzu an samo wani allotrope na polymer na wannan abu, wanda ake kira "black nitrogen".

An samar da "Black Nitrogen" ta hanyar amfani da matsi na lu'u-lu'u a matsa lamba na yanayi miliyan 1,4 a zafin jiki na 4000 ° C. A karkashin irin wannan yanayi, nitrogen ya sami tsarin da ba a taɓa yin irinsa ba - lattice ɗinsa na crystal ya fara kama da lattice ɗin crystal na baƙar fata, wanda ya haifar da kiran jihar da aka samu "baƙar nitrogen." A wannan yanayin, nitrogen yana da nau'i biyu, albeit zigzag, tsari. Matsakaicin nau'i biyu yana nuna cewa haɓakar nitrogen a cikin wannan jihar na iya ɗan kwafi kaddarorin graphene, wanda zai iya zama da amfani yayin amfani da abun cikin kayan lantarki.

Bugu da kari, a cikin sabuwar jihar, ana hada kwayoyin atom na nitrogen ta hanyar hada-hadar kudi guda daya, wadanda suka yi rauni sau shida idan aka kwatanta da na biyun, kamar yadda lamarin yake a yanayin yanayi na yau da kullun (N2). Wannan yana nufin cewa dawowar "black nitrogen" zuwa matsayinta na yau da kullum zai kasance tare da sakin makamashi mai mahimmanci, kuma wannan ita ce hanyar man fetur ko man fetur. Amma duk wannan yana gaba, kuma ya zuwa yanzu ba ko da wani mataki da aka dauka a kan wannan tafarki, amma kawai - sun duba ta cikin keyhole kuma ga wani abu.
