Siv graphene li cas? Ob qho piv txwv ntawm daim ntawv thov cia koj nkag siab txog qhov kev siv graphene
Xyoo 2010, Geim thiab Novoselov yeej qhov khoom plig Nobel hauv physics rau lawv txoj haujlwm ntawm graphene. Qhov khoom plig no tau tso ib qho kev xav tob rau ntau tus neeg. Tom qab tag nrho, tsis yog txhua yam cuab yeej sim Nobel zoo li daim kab xev nplaum, thiab tsis yog txhua yam khoom tshawb fawb zoo li khawv koob thiab yooj yim to taub li R...Nyeem ntxiv -
Kev tshawb fawb txog kev tiv thaiv corrosion ntawm graphene / carbon nanotube reinforced alumina ceramic coating
1. Kev npaj txheej Txhawm rau kom yooj yim rau kev sim electrochemical tom qab, 30mm yog xaiv × 4 hli 304 stainless hlau ua lub hauv paus. Txhuam thiab tshem tawm cov txheej oxide seem thiab cov xeb ntawm qhov chaw ntawm lub substrate nrog ntawv xuab zeb, muab tso rau hauv lub beaker uas muaj acetone, kho cov sta...Nyeem ntxiv -
(Lithium hlau anode) Interfacial theem ntawm cov electrolyte khoom tshiab anion-derived
Cov Khoom Siv Hluav Taws Xob Khoom Siv Hluav Taws Xob (SEI) yog siv dav los piav qhia txog theem tshiab tsim ntawm anode thiab electrolyte hauv cov roj teeb ua haujlwm. Cov roj teeb lithium (Li) hlau muaj zog ntau raug cuam tshuam los ntawm dendritic lithium deposition uas coj los ntawm SEI tsis sib xws. Txawm hais tias nws muaj qhov tshwj xeeb a ...Nyeem ntxiv -
Kev sib xyaw ua ke ntawm cov txheej txheem MoS2 uas muaj peev xwm ua haujlwm tau zoo
Cov txheej txheem MoS2 membrane tau ua pov thawj tias muaj cov yam ntxwv tshwj xeeb ntawm kev tsis lees txais ion, kev nkag mus rau dej siab thiab kev ruaj khov mus sij hawm ntev, thiab tau pom tias muaj peev xwm zoo hauv kev hloov pauv / khaws cia lub zog, kev ntsuas, thiab kev siv ua haujlwm raws li cov khoom siv nanofluidic. Cov tshuaj hloov kho membrane ntawm ...Nyeem ntxiv -
Nickel-catalyzed deaminative Sonogashira coupling ntawm alkylpyridinium ntsev qhib los ntawm NN2 pincer ligand
Alkynes muaj ntau nyob rau hauv cov khoom ntuj, cov khoom siv biologically active thiab cov ntaub ntawv ua haujlwm organic. Tib lub sijhawm, lawv kuj yog cov khoom siv tseem ceeb hauv kev tsim cov organic thiab tuaj yeem dhau los ua ntau yam kev hloov pauv tshuaj lom neeg. Yog li ntawd, kev txhim kho yooj yim thiab ua tau zoo ...Nyeem ntxiv
