Lub Teb Chaws Asmeskas Pab Ua Cov Hom Tshiab Uas Muaj Cov Zinc Thiab Organic Cov Cheeb Tsam, Muaj Kev Yooj Yim.

Mar 16, 2018

Quartz iav yog ib txwm ua los ntawm silica (SiO2), thiab tseem coj los ntawm kev ua cov ntoo, hlau thiab hlau ntau yam xws li ntau hom iav, cov neeg txawv teb chaws tsis ntev los no tau tsim ib hom tshiab ntawm cov iav "ua los ntawm cov hlau thiab cov organic compounds ZIF- 62, cov khoom tshiab no tsis zoo dua li cov laus hom yooj yim tsim iav tib lub sij hawm, kuj muaj ntau yooj.


Dhau li ntawm qhov sib txawv ntawm cov xaim hluav taws xob, lub qauv tetrahedron ntawm ZIF-62 thiab SiO2 iav yog kwv yees li qub. Zinc (zinc) cov xaim hluav taws xob muaj ob lub tebchaw. Ob qho chaw sib xyaw organic yog imidazolate thiab benzimidazolate feem.


Tsis muaj teeb meem dab tsi ntawm iav, thiaj li ua kom lub cev tsis tshua zoo, cov txheej txheem yuav tau ceev faj kom muaj qhov sib npaug, feem ntau cov khoom yuav tsum tau txias txias rau hauv cua sov kom yaj, tuaj yeem tshwm ntsej muag zoo (Amorphous), thiab cov khoom no tsim nyob rau hauv lub khob iav thaum lub peev xwm hu ua "iav forming ability" (iav forming ability GFA).


Pab neeg pom tau hais tias nyob rau hauv cov kev kawm, nrog ntau dua benzimidazolate ntxiv, lub khob ua kom muaj peev xwm zoo dua, kom deb li deb, paub tias muaj li ntawm silica iav khob ua kom muaj peev xwm, tiam sis pawg ntseeg ntseeg tias ZIF-62 yuav rov sau dua tshiab , nws muaj ntau tshaj 50 hom iav hom muaj, txawm ntau yooj yim tshaj silicon iav.


Txawm li cas los xij, tseem muaj qee cov teeb meem uas yuav tsum tau daws hauv ZIF-62. Cov txheej txheem ntawm kev ua iav tau txais txiaj ntsig los ntawm ntau txhiab xyoo txhim kho, thiab ZIF-62 tseem yog nyob rau theem pib ntawm txoj kev tshawb no thiab tsis tuaj yeem sib tw nrog nws.


  

Ua ntej yuav ua qhov tshiab ntawm cov iav, pawg yuav tsum tau ua ntej coj los ntawm cov organic sib txuas, tom qab ntawd nrog aqueous zinc nitrate (hydrous zinc nitrate) thiab sib xyaw xyaw, thiab tom qab ntawd ua kom kub txog 800 degrees F (427 degrees C) thiab tswj kom muaj lub sij hawm ntawm lub sij hawm yuav tiav tag nrho, tab sis thaum lub ntsuas kub txog 980 degrees F (527 degrees C) thaum nws yuav pib yaj.


Pab neeg no tau siv spectroscopy thiab X txoj sab nrauv los soj ntsuam qee yam khoom ntiag tug, thiab ntsuas kev kho qhov muag thiab zauv ntawm Zif-62. Qee cov kev xeem tau ua tiav hauv New York Corelle (Corning), tab sis tseem muaj ntau yam yuav tsum tau kawm.

  

  

Txoj kev tshawb no co-sau John C. Mauro tau hais tias cov khoom siv ntawm iav yog qhov tshiab heev, tab sis lawv tau txiav txim tias lub khob tsim muaj peev xwm thiab kev muaj peev xwm, tiam sis peb tseem tsis to taub tag nrho nws cov khoom siv, peb kuj yuav tsum tau kawm txog kev tsim khoom li cas txheej txheem yog tsim rau huab hwm coj ntau lawm.


Pawg neeg xav kom xav kawm ntxiv txog PMMA, nrog rau cov txujci cobalt raws li cov iav (cobalt), uas tau muab luam tawm nyob rau hauv phau ntawv Journal Science Advances.
