Izakhiwo eziyingqayizivele zama-neutron ziwenza ama-probe angenakuqhathaniswa wesayensi yezinto. Nakuba ziyizinhlayiya, zinemvelo efana negagasi, ezinamaza amaza ebangeni elifanayo namaza e-X-ray, futhi zidlula kalula odabeni oluqinile. Njengama-X ray, ayahlehla, ayahlakaza, futhi aphazamisane ngendlela eyakhayo futhi ebhubhisayo. Ngokungafani nama-X-ray, asebenzisana ngokuyinhloko namafu e-electron azungeze ama-athomu ento, ngokusebenzisa amandla kazibuthe, ama-neutron asebenzelana ikakhulukazi nama-nuclei e-athomu, ngokusebenzisa amandla enuzi aqinile; ngenxa yalokho, zingasetshenziswa futhi ukunquma ukwakheka kwezinto, ngazo zombili i-elementi ne-isotopu. Ama-Neutron asebenzisana nezinto ezilula kakhulu njengama-elementi asindayo, kwesinye isikhathi aqine nakakhulu, futhi amathuba amaningi akhona okuhlolwa kokulebula kwe-isotopu. Isibonelo, amasu okuhlakazeka kwe-neutron ayibona kalula i-hydrogen, okuyithagethi enzima noma engenakwenzeka kwezinye izindlela eziningi zokuhlaziya. Baphinde bahlukanise i-hydrogen ne-deuterium njengobusuku nemini.

Le webinar ichaza inhlanganisela yezilinganiso ze-electrochemical ne-neutron reflectometry, indlela yokuhlaziya indawo, ukuze inikeze ulwazi lwe-sub-nanometre lokuqanjwa kanye nesakhiwo endaweni yama-electrode ngaphansi kokulawulwa kwe-electrochemical okungatholakali nganoma iyiphi enye indlela. Izibonelo ezibonisayo zisebenzisa i-neutron reflectometry ukuqapha ukukhula kwefilimu ye-oxide kanye nokumuncwa kwe-hydrogen ku-titanium, zirconium nethusi.

Iseshini ye-Q&A esebenzisanayo ilandela isethulo.

James (Jamie) Noel isazi se-electrochemist kanye nososayensi bokugqwala ocwaningo lwakhe luhlanganisa izifundo zokucekelwa phansi kukaphethiloli wenuzi nezinto zokuqukatha ukuze kulahlwe unomphela imfucumfucu yenuzi. Uhola iqembu elikhulu nelihlukahlukene locwaningo elenza ucwaningo lokuhlola ezicini eziningi zokugqwala kwethusi, i-carbon steel, i-uranium dioxide, izinsimbi ezingenasici, ama-nickel alloys, nezinye izinto. Abalingani bakhe bocwaningo lwemboni bahlanganisa iNuclear Waste Management Organisation (NWMO, Toronto), iSweden Nuclear Fuel and Waste Management Company (SKB, Sweden), National Cooperative for the Disposal of Radioactive Waste (Nagra, Switzerland), Nuclear Waste Management Organisation. yaseJapan (NUMO, Tokyo), kanye neCanadian Nuclear Laboratories (CNL, Chalk River). U-Jamie uthole iziqu ze-BS ne-MS kukhemistri eNyuvesi yaseGuelph kanye ne-PhD kukhemistri eNyuvesi yaseManitoba. Ufundisa i-ECS Short Courses on the Fundamentals of Electrochemistry emihlanganweni yeNhlangano eqhutshwa kabili ngonyaka, ubambe iqhaza kakhulu ne-ECS Corrosion Division kanye neKomidi Lezemfundo Le-ECS, futhi ungumhleli Ohlanganisayo Ijenali ye-CORROSION. Imiklomelo yakhe ihlanganisa i-ECS RC Jacobsen kanye ne-Lash Miller Awards, Fellow of ECS, kanye ne-Western University Distinguished Research Professorship, i-Faculty Scholar Award, kanye ne-Florence Bucke Science Prize. Ubhale ngokuhlanganyela izindatshana zejenali ezinonompempe ezingaphezu kwe-130, amaphepha ezinqubo zengqungquthela ezinompempe ezingama-50, imibiko yezohwebo engama-20, nezahluko zezincwadi ezinhlanu - futhi wahlakaza ama-neutron ambalwa endleleni.
