Rahotanni daga kasashen waje sun bayyana cewa, Feng Lin, mataimakin farfesa a Sashen Kimiyyar Kimiyya a Kwalejin Kimiyya ta Virginia Tech, tare da tawagarsa, sun gano cewa, da alama bacewar batir da wuri na da nasaba da kaddarorin da ke tattare da kwayar cutar, amma bayan tuhume-tuhume da yawa. Bayan looping, yadda waɗancan ɓangarorin suka dace tare ya fi mahimmanci.

"Wannan binciken ya bayyana sirrin yadda ake ƙirƙira da ƙirƙira na'urorin batir don tsawon rayuwar batir," in ji Lin. A halin yanzu, dakin gwaje-gwaje na Lin yana aiki don sake fasalin na'urorin batir don ƙirƙirar caji mai sauri, mai rahusa, Tsawon rai da gine-ginen lantarki masu dacewa da muhalli.

Tushen hoto: Feng Lin

"Lokacin da tsarin gine-ginen lantarki ya ba da damar kowane nau'in kwayar halitta don amsawa da sauri zuwa siginar lantarki, za mu sami babban akwatin kayan aiki don yin cajin batura cikin sauri," in ji Lin. "Mun yi farin cikin ba da damar fahimtar zamani na gaba na batura masu caji mai sauƙi. ”

An gudanar da binciken tare da haɗin gwiwar Ma'aikatar Makamashi ta Amurka SLAC National Accelerator Laboratory, Jami'ar Purdue da Turai Synchrotron Radiation Facility. Zhengrui Xu da Dong Ho, abokan karatun digiri a cikin dakin gwaje-gwaje na Lin, suma mawallafa ne a kan takarda, suna jagorantar kera na'urorin lantarki, kera batir, da ma'aunin aikin baturi, da kuma taimakawa tare da gwaje-gwajen X-ray da nazarin bayanai.

"Asali tubalan su ne wadannan barbashi da ke samar da na'urorin lantarki na baturi, amma idan aka haɓaka, waɗannan barbashi suna hulɗa da juna," in ji masanin kimiyya SLAC Yijin Liu, wani ɗan'uwa a Stanford Synchrotron Radiation Light Source (SSRL). "Idan kuna son yin ingantattun batura, kuna buƙatar sanin yadda ake haɗa ƙwayoyin cuta tare."

A wani bangare na binciken, Lin, Liu da sauran abokan aiki sun yi amfani da dabarun hangen nesa na kwamfuta don nazarin yadda nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan batura masu caji ke rushewa cikin lokaci. Manufar wannan lokacin shine nazarin ba kawai nau'ikan kwayoyin halitta ba, har ma da hanyoyin da suke aiki tare don tsawaita ko rage rayuwar baturi. Maƙasudin ƙarshe shine koyon sababbin hanyoyin da za a tsawaita rayuwar ƙirar baturi.

A matsayin wani ɓangare na binciken, ƙungiyar ta yi nazarin cathode baturi tare da hasken X-ray. Sun yi amfani da hoton hoto na X-ray don sake gina hoton 3D na cathode na baturi bayan zagayowar caji daban-daban. Daga nan sai suka yanke waɗannan hotuna na 3D zuwa jerin nau'ikan nau'ikan 2D kuma suka yi amfani da hanyoyin hangen nesa na kwamfuta don gano ɓarna. Baya ga Lin da Liu, binciken ya hada da mai binciken SSRL na gaba da digiri na biyu Jizhou Li, farfesa injiniyan injiniya na Jami'ar Purdue Keije Zhao, da dalibin da ya kammala karatun digiri na jami'ar Purdue Nikhil Sharma.

A karshe masu binciken sun gano wasu barbashi sama da 2,000, inda suka yi lissafin ba wai kawai halayen barbashi kamar girman, siffa, da radadin saman ba, har ma da fasali kamar sau nawa barbashi ke hulda da juna kai tsaye da kuma nawa barbashi suka canza siffar.

Bayan haka, sun duba yadda kowace kadara ta haifar da rugujewar barbashi, inda suka gano cewa bayan zagayowar caji guda 10, manyan abubuwan da suka fi daukar hankali su ne kaddarorin nau’ukan nau’ukan nau’ukan da suka hada da yadda kwayoyin halitta suke da siffar siffar da kuma girman girman barbashi zuwa saman fili. Bayan zagayowar 50, duk da haka, haɗakarwa da kaddarorin rukuni sun kori ɓarnar barbashi-kamar nisan barbashi guda biyu, nawa sifar ta canza, da kuma ko ɓangarorin ƙwallon ƙwallon ƙafa mafi tsayi suna da irin wannan daidaitawa.

"Dalilin ba shine kawai barbashi da kansa ba, amma hulɗar barbashi da barbashi," in ji Liu. Wannan binciken yana da mahimmanci saboda yana nufin cewa masana'antun na iya haɓaka dabarun sarrafa waɗannan kaddarorin. Misali, za su iya amfani da filayen maganadisu ko lantarki Daidaita barbashi masu tsayi da juna, sabon binciken ya nuna cewa hakan zai tsawaita rayuwar batir.

Lin ya kara da cewa: "Mun yi bincike sosai kan yadda ake sanya batir EV aiki yadda ya kamata a karkashin caji mai sauri da yanayin zafi. Baya ga zayyana sabbin kayan da za su iya rage farashin batir ta hanyar amfani da arha da ɗimbin albarkatun ƙasa, dakin gwaje-gwajen mu Har ila yau, an yi ƙoƙarin fahimtar halin baturi daga ma'auni. Mun fara nazarin kayan batir da yadda suke mayar da martani ga munanan muhalli.”
