Sekureva kwenhau dzekunze dzenhau, Feng Lin, purofesa anobatana muDhipatimendi reChemistry kuVirginia Tech College yeScience, uye timu yake yekutsvagisa yakaona kuti kupera kwebhatiri kwekutanga kunoratidzika kunge kuri kutungamirwa nemidziyo yemagetsi ega ega, asi mushure memhosva dzakawanda. Mushure mekupeta, kuti zvimedu izvi zvinobatana sei zvakanyanya kukosha.
"Chidzidzo ichi chinoburitsa zvakavanzika zvekugadzira nekugadzira magetsi ebhatiri kwehupenyu hurefu hwebhatiri," akadaro Lin. Parizvino, Lin's lab iri kushanda pakugadzirisazve bhatiri maelectrode kuti agadzire kukurumidza-kuchaja, kuderera-mutengo, Hupenyu hurefu uye zvakatipoteredza zvine hushamwari electrode architecture.
Mufananidzo kunobva: Feng Lin
"Apo electrode architecture inobvumira imwe neimwe particle kuti ipindure nokukurumidza kune zviratidzo zvemagetsi, tichava nebhokisi guru rekushandisa kukurumidza kuchaja mabhatiri," akadaro Lin. “Tinofara kugonesa kunzwisisa kwedu kwechizvarwa chinotevera chemabhatiri anodhura anokurumidza kuchaja. ”
Tsvagiridzo iyi yakaitwa mukubatana neDhipatimendi reUS reMagetsi's SLAC National Accelerator Laboratory, Purdue University uye European Synchrotron Radiation Facility. Zhengrui Xu naDong Ho, postdoctoral shamwari muLin's lab, zvakare vanyori vanyori papepa, vachitungamira kugadzirwa kwemagetsi, kugadzirwa kwebhatiri, uye kuyerwa kwekuita kwebhatiri, uye kubatsira neX-ray kuyedza uye kuongororwa kwedata.
"Zvivharo zvekuvaka ndezvimedu zvinogadzira mabhatiri emagetsi, asi kana akakwidziridzwa, zvimedu izvi zvinodyidzana," akadaro musayendisiti weSLAC Yijin Liu, shamwari paStanford Synchrotron Radiation Light Source (SSRL). "Kana iwe uchida kugadzira mabhatiri ari nani, unofanirwa Kuziva maitiro ekuisa zvidimbu pamwechete."
Sechikamu chechidzidzo, Lin, Liu nevamwe vaaishanda navo vakashandisa matekiniki ekuona komputa kudzidza kuti zvimedu zvega zvega zvinoumba maelectrode emabhatiri anochajika anoparara sei nekufamba kwenguva. Chinangwa panguva ino ndechekudzidza kwete chete zvimedu zvega, asiwo nzira dzavanoshanda nadzo pamwe kuwedzera kana kuderedza hupenyu hwebhatiri. Chinangwa chekupedzisira ndechekudzidza nzira nyowani dzekuwedzera hupenyu hwemabhatiri magadzirirwo.
Sechikamu chechidzidzo, timu yakadzidza bhatiri cathode ine X-rays. Vakashandisa X-ray tomography kuvakazve mufananidzo we3D webhatiri cathode mushure mekutenderera kwakasiyana kwekuchaja. Vakabva vacheka iyi mifananidzo ye3D kuita nhevedzano ye2D zvimedu uye vakashandisa nzira dzekuona komputa kuona zvimedu. Pamusoro paLin naLiu, chidzidzo ichi chaisanganisira SSRL postdoctoral muongorori Jizhou Li, Purdue University mechanical engineering purofesa Keije Zhao, uye Purdue University akapedza kudzidza Nikhil Sharma.
Vatsvakurudzi vakapedzisira vaona zvinopfuura zviuru zviviri zvezvimedu zvega, zvisingaverengeki chete chimiro chega chega senge saizi, chimiro, uye kushata kwepamusoro, asi zvakare maficha akadai sekuti kangani zvikamu zvacho zvaisangana zvakananga uye kuti zvakadii zvikamu zvakachinja chimiro.
Tevere, vakatarisa kuti chivakwa chega chega chakaita sei kuti zvimedu zviputsike, uye vakaona kuti mushure menguva gumi yekuchaja, zvinhu zvikuru zvaive zvimiro zvezvimedu zvega, kusanganisira kutenderera kwainge kwakaita zvimedu uye chiyero chehuwandu hwehuwandu kusvika pamusoro penzvimbo. Mushure mematenderedzwa makumi mashanu, zvisinei, kubatanidza uye zvivakwa zveboka zvakafambisa kuparara kwechikamu-sekuti zvikamu zviviri izvi zvaive zvakaparadzana zvakadii, chimiro chakachinja sei, uye kana twumwe twurefu twakaita sebhora renhabvu raive nemaitiro akafanana.
"Chikonzero hachisiri icho chimedu pachacho, asi kupindirana kwechikamu," Liu akadaro. Kuwana uku kwakakosha nekuti zvinoreva kuti vagadziri vanogona kugadzira matekiniki ekudzora zvivakwa izvi. Semuenzaniso, vanogona kukwanisa kushandisa magineti kana emagetsi minda Kubatanidza zvidimbu zvakarebesa pamwe chete, zvichangobva kuwanikwa zvinoratidza kuti izvi zvichawedzera hupenyu hwebhatiri. "
Lin akawedzera kuti: "Isu tanga tichitsvaga zvakanyanya maitiro ekuita kuti mabhatiri eEV ashande nemazvo pasi pekukurumidza kuchaja uye nemamiriro ekushisa akadzikama. Pamusoro pekugadzira zvinhu zvitsva zvinogona kuderedza mutengo webhatiri nekushandisa zvakachipa uye zvakanyanya kuwanda, rabhoritari yedu Pakave nekuedza kunoenderera mberi kwekunzwisisa maitiro ebhatiri kure nekuenzana. Tatanga kudzidza zvinhu zvebhatiri uye maitiro azvo kunzvimbo dzakaoma. "
