Kev Taw Qhia thiab Kev Siv Nyiaj Nitrate
Silver nitrate yog cov tshuaj sib xyaw nrog cov mis AgNO3.Nws yog ntsev ntawm cov nyiaj, thiab yog dav siv nyob rau hauv ntau yam lag luam xws li kev yees duab, tshuaj, thiab chemistry.Nws txoj kev siv tseem ceeb yog ua cov tshuaj reagent hauv cov tshuaj tiv thaiv, vim nws tuaj yeem nkag siab nrog halides, cyanides, thiab lwm yam sib xyaw.Nws ...Nyeem ntxiv -
Dab tsi yog kev siv graphene?Ob daim ntawv thov ua rau koj nkag siab txog daim ntawv thov kev cia siab ntawm graphene
Xyoo 2010, Geim thiab Novoselov yeej Nobel nqi zog hauv physics rau lawv txoj haujlwm ntawm graphene.Qhov khoom plig no tau ua rau muaj kev xav tob rau ntau tus neeg.Tom qab tag nrho, tsis yog txhua qhov kev sim khoom plig Nobel muaj ntau yam zoo li daim kab xev nplaum, thiab tsis yog txhua qhov kev tshawb fawb cov khoom yog tej yam yees siv thiab yooj yim to taub li R ...Nyeem ntxiv -
Kawm txog kev tiv thaiv corrosion ntawm graphene / carbon nanotube reinforced alumina ceramic txheej
1. Kev npaj txheej txhawm rau txhawm rau txhawm rau txhawm rau kuaj tom qab electrochemical, 30mm yog xaiv × 4 hli 304 stainless hlau ua lub hauv paus.Polish thiab tshem tawm cov seem oxide txheej thiab xeb me ntsis ntawm qhov chaw ntawm lub substrate nrog sandpaper, muab tso rau hauv lub beaker uas muaj acetone, kho cov sta...Nyeem ntxiv -
(Lithium hlau anode) Interfacial theem ntawm anion-derived khoom electrolyte tshiab
Solid Electrolyte Interphase (SEI) yog dav siv los piav txog cov theem tshiab tsim ntawm cov anode thiab cov electrolyte hauv cov roj teeb ua haujlwm.Lub zog loj ntom ntom lithium (Li) cov roj teeb hlau muaj kev cuam tshuam loj heev los ntawm dendritic lithium deposition coj los ntawm non-uniform SEI.Txawm hais tias nws muaj qhov tshwj xeeb ...Nyeem ntxiv -
Muaj peev xwm-dependention sieving ntawm functionalized txheej MoS2 membranes
Cov txheej txheej MoS2 tau raug pov thawj tias muaj cov yam ntxwv tshwj xeeb ion rejection, cov dej permeability siab thiab cov kuab tshuaj mus ntev, thiab tau pom muaj peev xwm loj hauv kev hloov pauv hluav taws xob / khaws cia, kev hnov lus, thiab siv tau zoo li cov khoom siv nanofluidic.Chemically modified membranes ntawm ...Nyeem ntxiv -
Nickel-catalyzed deaminative Sonogashira coupling ntawm alkylpyridinium ntsev enabled los ntawm NN2 pincer ligand
Alkynes muaj dav nyob rau hauv cov khoom ntuj, biologically active molecules thiab organic functional khoom.Nyob rau tib lub sijhawm, lawv kuj tseem yog cov nruab nrab tseem ceeb hauv cov organic synthesis thiab tuaj yeem ua rau muaj kev hloov pauv tshuaj lom neeg ntau.Yog li ntawd, kev txhim kho ntawm kev yooj yim thiab ua tau zoo ...Nyeem ntxiv
