Intshayelelo kunye nosetyenziso lweSilver Nitrate
ISilver nitrate yikhompawundi yemichiza enefomula ethi AgNO3.Yityuwa yesilivere, kwaye isetyenziswa kakhulu kumashishini ahlukeneyo afana nokufota, amayeza kunye nekhemistri.Ukusetyenziswa kwayo okuphambili kufana ne-reagent kwi-chemical reactions, njengoko inokusabela ngokukhawuleza kunye ne-halides, i-cyanides, kunye nezinye iikhompawundi.I...Funda ngokugqithisileyo -
Yintoni ukusetyenziswa kwegraphene?Iimeko ezimbini zesicelo zikuvumela ukuba uqonde ithemba lesicelo segraphene
Ngo-2010, uGeim noNovoselov baphumelela ibhaso leNobel kwifiziksi ngomsebenzi wabo kwigraphene.Eli wonga lishiye uchuku kubantu abaninzi.Ngapha koko, ayizizo zonke izixhobo zovavanyo zeBhaso likaNobel zixhaphake njengeteyiphu yokuncamathelisa, kwaye ayizizo zonke izinto zophando ezinomlingo kwaye kulula ukuyiqonda njengeR...Funda ngokugqithisileyo -
Uphononongo malunga nokumelana nomhlwa kwegraphene / carbon nanotube eyomeleziweyo yokwaleka kwe-alumina ceramic
1. Ukulungiswa kokugquma Ukuze kuququzelelwe uvavanyo lwe-electrochemical kamva, i-30mm ikhethiwe × 4 mm 304 insimbi engenasici njengesiseko.Polish kwaye ususe intsalela ye-oxide kunye namabala erusi kumphezulu we-substrate nge-sandpaper, uwafake kwi-beaker ene-acetone, uphathe i-sta...Funda ngokugqithisileyo -
(I-Lithium metal anode) Isigaba sokudibanisa ubuso be-anion-derived electrolyte esomeleleyo esitsha
I-Solid Electrolyte Interphase (SEI) isetyenziswa ngokubanzi ukuchaza isigaba esitsha esenziwe phakathi kwe-anode kunye ne-electrolyte kwiibhetri ezisebenzayo.Amandla aphezulu e-lithium (Li) iibhetri zetsimbi zithintelwa kakhulu yi-dendritic lithium deposition ekhokelwa yi-SEI engeyiyo iyunifomu.Nangona inento eyodwa...Funda ngokugqithisileyo -
Ukusefa okunokwenzeka kokuxhomekeka kweenwebu ze-MoS2 ezisebenzayo
I-membrane ye-MoS2 elayishiweyo ibonakaliswe ukuba ineempawu ezinqabileyo zokulahla i-ion, ukugqithiswa kwamanzi aphezulu kunye nokuzinza kwe-solvent yexesha elide, kwaye ibonise amandla amakhulu ekuguquleni amandla / ukugcinwa, ukuva, kunye nokusetyenziswa okusebenzayo njengezixhobo ze-nanofluidic.Iinwebu ezilungiswe ngokwekhemikhali ze...Funda ngokugqithisileyo -
