Iyini ukusetshenziswa kwe-graphene? Amacala amabili ohlelo lokusebenza akuvumela ukuthi uqonde ithemba lesicelo se-graphene
Ngo-2010, uGeim noNovoselov bawina uMklomelo KaNobel ku-physics ngomsebenzi wabo we-graphene. Lo mklomelo ushiye umxhwele kakhulu kubantu abaningi. Phela, akuwona wonke amathuluzi okuhlola weNobel Prize avamile njenge-adhesive tape, futhi akuyona yonke into yocwaningo enomlingo futhi kulula ukuyiqonda njenge-R...Funda kabanzi -
Ucwaningo mayelana nokumelana nokugqwala kwe-graphene / carbon nanotube eqinisiwe i-alumina ceramic coating
1. Ukulungiswa kokumboza Ukuze kube lula ukuhlolwa kwe-electrochemical yakamuva, i-30mm ikhethwa × 4 mm 304 insimbi engagqwali njengesisekelo. Pholisha bese ususa ungqimba lwe-oxide osele kanye namabala okugqwala phezu kwe-substrate nge-sandpaper, ukubeke ebhekhani eline-acetone, uphathe i-sta...Funda kabanzi -
(I-Lithium metal anode) Isigaba sokusebenzelana sobuso se-electrolyte eqinile esuselwa ku-anion
I-Solid Electrolyte Interphase (SEI) isetshenziswa kabanzi ukuchaza isigaba esisha esakhiwe phakathi kwe-anode ne-electrolyte kumabhethri asebenzayo. Amandla aphezulu we-lithium (Li) amabhethri ensimbi athikamezwa kakhulu ukufakwa kwe-lithium ye-dendritic eqondiswa yi-SEI engafani. Nakuba ine-ehlukile...Funda kabanzi -
Ukusefa okungaba khona kokuncika kwezingqimba ze-MoS2 ezinengqimba
I-membrane ye-MoS2 enezingqimba ifakazelwe ukuthi inezici ezihlukile zokwenqaba i-ion, ukukwazi ukungena kwamanzi aphezulu kanye nokuzinza kwe-solvent yesikhathi eside, futhi ibonise amandla amakhulu ekuguquleni amandla/isitoreji, inzwa, nezinhlelo zokusebenza ezingokoqobo njengamadivayisi e-nanofluidic. Ama-membrane ashintshwe ngamakhemikhali...Funda kabanzi -
I-Sonogashira ebulalayo eyenziwe nge-nickel-catalyzed of alkylpyridinium salts inikwe amandla yi-NN2 pincer ligand
Ama-alkynes akhona kakhulu emikhiqizweni yemvelo, ama-molecule asebenzayo we-biologically kanye nezinto zokusebenza eziphilayo. Ngasikhathi sinye, zingabaxhumanisi ezibalulekile ku-organic synthesis futhi zingabhekana nokusabela okuchichimayo kokuguqulwa kwamakhemikhali. Ngakho-ke, ukuthuthukiswa kokulula nokusebenza kahle ...Funda kabanzi
