Linda Nazar

**Linda Faye Nazar** OC FRSC FRS babban kujera ne na Bincike na Kanada a cikin Kayan Kasuwanci da Kyakkyawan Bincike Farfesa na Kimiyya a Jami'ar Waterloo . Tana haɓaka kayan aiki don adana makamashi na lantarki da juyawa. Nazar ya nuna cewa ana iya amfani da sinadarai masu haɗuwa don inganta ƙarfin makamashi na Batirin lithium-sulphur. An ba ta lambar yabo ta Cibiyar Kimiyya ta Kanada ta 2019.

## Rayuwa ta farko da ilimi
Nazar ta yi karatun ilmin sunadarai a Jami'ar British Columbia, inda ta sami digiri na farko a shekarar 1978.  An yi wahayi zuwa gare ta don nazarin ilmin sunadarai bayan farfesa na shekara ta farko ya yi wahayi. Mahaifinta ya horar da shi a matsayin masanin kimiyya kuma ya gudanar da kasuwancin kansa na yin kayan ado. Nazar ta shiga Jami'ar Toronto don karatun digiri, kuma ta kammala PhD a karkashin kulawar Geoffrey Ozin a shekarar 1984. Bayan ta sami digiri, ta yi aiki a matsayin mai bincike na postdoctoral tare da Allan Jacobson a Kamfanin Bincike da Injiniya na Exxon,  kafin ta shiga Jami'ar Waterloo a ƙarshen shekarun 1980, lokacin da ta zama mai sha'awar ilimin lantarki da ilmin sunadarai na Inorganic. 

## Bincike da aiki
Nazar tana aiki a cikin ilmin sunadarai a Jami'ar Waterloo, inda take tsara na'urorin adana makamashi da tsarin electrochemical. Kungiyar bincikenta ta kirkiro sabbin kayan aiki da nanostructures don batirin lithium-sulfur, gami da abubuwan da aka haɗa. Ta haɓaka bincike na tsari don fahimtar yadda yanayin kayan da ke iya caji / hanyoyin redox na ionic ke tasiri ga ayyukansu. Wadannan dabarun sun hada da ma'aunin magnetic na nukiliya (NMR), electrochemistry, AC Impedance Spectroscopy da ma'anonin diffraction na X-ray. Nazar ta kasance memba ne na kafa Cibiyar Waterloo don Nanotechnology .  Nazar an san shi da kasancewa "babban iko a cikin kayan ci gaba".  An ba ta lambar yabo ta Kanada Research Chair a shekara ta 2004, wanda aka sabunta a shekara ta 2008 da 2012.   A shekara ta 2009 Nazar ta shiga Cibiyar Fasaha ta California a matsayin Masanin Mahimmanci.   A cikin 2013 an ba ta kyautar dala miliyan 1.8 daga Majalisar Bincike ta Kasa don bincika kayan adana makamashi don aikace-aikacen mota.

Nazar yana da sha'awar kayan ajiya waɗanda suka wuce lithium-ion_battery" id="mwZQ" rel="mw:WikiLink" title="Lithium-ion battery">Batirin lithium-ion, Batirin sodium-ion.[1][2][3][4] Batirin Lithium-ion shine batirin da aka zaba a cikin motocin lantarki na hybrid, amma damuwa ta taso game da samar da lithium a duniya. Ayyukanta na farko sun haɓaka gine-ginen carbon a matsayin tsarin cathodes, suna haɓaka halayensu da ƙarfin fitarwa.[5] Ta nuna cewa ana iya amfani da sinadarin carbon don inganta ƙarfin makamashi na Batirin lithium-sulphur.[6] Ta nuna cewa yana yiwuwa a ƙirƙiri tsarin carbon mesoporous wanda ke hana girma na nanofillers na sulphur, wanda ya inganta ajiyar makamashi da sakewa.[5]

Nazar ya lissafa Batirin lithium-sulphur mai arha zai iya ɗaukar motocin lantarki sau biyu kamar fasahar lithium-ion ta yanzu. Sulphur abu ne mai yawa wanda za'a iya amfani dashi don maye gurbin cobalt oxide a cikin Batirin lithium-ion. Abin takaici, sulphur na iya narkewa cikin maganin lantarki, kuma za a rage shi ta hanyar lantarki don samar da polysulphides. Har ila yau, suna da saukin kamuwa da tsayayyar ciki da ƙarfin da ke raguwa a kan keke. Wadannan ƙalubalen za a iya shawo kan su ta hanyar ƙirƙirar nanostructures a cikin electrodes. Hakanan ana iya yin sinadarai masu haɗuwa daga Manganese dioxide, wanda ke daidaita polysuplphides a cikin Batirin lithium-sulphur. Manganese dioxide yana rage sulphides ta hanyar polythiosulphanates, kuma yana iya tsayayya da sake zagayowar fitarwa 2,000 ba tare da asarar capacitance ba. Ta kuma haɓaka Batirin iskar oxygen na lithium, waɗanda suke da nauyi mai sauƙi tare da ƙarfin makamashi. A cikin Batirin iskar oxygen na lithium, peroxide" id="mwww" rel="mw:WikiLink" title="Superoxide">superoxide da peroxide na iya aiki don lalata sel; iyakance rayuwarsu. Idan an maye gurbin electrolyte da gishiri mai narkewa da kuma cathode mai ƙuƙwalwa tare da oxide na ƙarfe, peroxide ba ya samuwa. Nazar ya yi aiki a kan supercapacitors da kayan polyanion.

An sanya ta Farfesa a Jami'ar Waterloo a shekarar 2016 kuma tana da kujerar Bincike ta Tier 1 Canada a cikin Kayan Makamashi na Kasuwanci.  Tun daga shekara ta 2014 Nazar ta yi aiki a cikin kwamitin daraktocin taron kasa da kasa kan Li-Batteries .  Tana aiki a kan allon edita na mujallu Angewandte Chemie, Energy & Environmental Science da Journal of Materials Chemistry A .
