Abahanga mu by’imashini bo muri Kaminuza ya Rice barimo guhindura morokiside karubone mo aside asetiki (ikinyabutabire gikoreshwa cyane giha vinegere uburyohe bukomeye) binyuze mu cyuma gikomeza gukoresha ingufu, gishobora gukoresha neza amashanyarazi ashobora kuvugururwa kugira ngo gikore ibintu bisukuye cyane.
Uburyo bwo gupima amashanyarazi muri laboratwari y’abahanga mu by’imiti n’ibinyabuzima bo muri Kaminuza ya Rice mu Ishuri ry’Ubwubatsi rya Brown ryakemuye ikibazo cy’igerageza ryakozwe mbere ryo kugabanya monoxide ya karubone (CO) ikaba aside asetiki. Izi nzira zisaba intambwe zindi kugira ngo zisukure icyo gicuruzwa.
Iyi reactor idahungabanya ibidukikije ikoresha umuringa wa nanometero nk'umusemburo w'ingenzi n'umusemburo udasanzwe w'amashanyarazi.
Mu masaha 150 yo gukora muri laboratwari, aside asetiki iri mu gipimo cy'amazi cyakozwe n'iki gikoresho yageze kuri 2%. Ubuziranenge bw'igice cya aside buri ku kigero cya 98%, ari nabyo byiza kurusha igice cya aside cyakozwe no kugerageza kwa mbere guhindura mozode karubone mo lisansi y'amazi.
Aside asetiki ikoreshwa nk'ikintu kirinda ubushyuhe mu buvuzi hamwe na vinegere n'ibindi biribwa. Ikoreshwa nk'ikintu kiyungurura irangi, amarangi n'ibindi bisigazwa; mu gukora acetate ya vinyl, acetate ya vinyl niyo ibanziriza kole isanzwe y'umweru.
Uburyo bwa Rice bushingiye ku cyuma gitunganya amashanyarazi kiri muri laboratwari ya Wang kandi kigakora aside formike ikomoka kuri dioxyde de carbone (CO2). Ubu bushakashatsi bwashyizeho ishingiro rikomeye kuri Wang (uherutse gushyirwa mu mwanya wa Packard Fellow), wahawe inkunga ya miliyoni 2 z'amadolari y'Amerika n'Ikigo cy'Igihugu gishinzwe Ubumenyi (NSF) kugira ngo akomeze gushakisha uburyo bwo guhindura imyuka ihumanya ikirere mo ibikomoka ku binyabiziga.
Wang yagize ati: “Turimo kuvugurura ibicuruzwa byacu biva kuri aside formic ya karuboni imwe bijya kuri aside formic ya karuboni ebyiri, ibyo bikaba bigoye cyane.” “Abantu basanzwe bakora aside asetiki mu electrolyte z’amazi, ariko baracyafite imikorere mibi kandi ibyo bicuruzwa ni ikibazo cyo gutandukanya electrolyte.”
Senftle yongeyeho ati: “Birumvikana ko aside asetiki isanzwe idakorwa muri CO2 cyangwa CO2.” “Iki ni cyo kibazo: turimo kunyunyuza imyuka y’imyanda dushaka kugabanya tukayihinduramo ibikoresho by’ingirakamaro.”
Hakozwe ubwitonzi hagati ya catalyst y'umuringa na electrolyte ikomeye, maze electrolyte ikomeye yimurirwa mu cyuma gitunganya aside formike. Wang yagize ati: “Rimwe na rimwe umuringa ukora imiti mu nzira ebyiri zitandukanye.” “Ushobora kugabanya monoxide ya karuboni ikaba aside asetiki na alcool. Twakoze agace gafite isura ishobora kugenzura ihuriro rya karuboni na karuboni, kandi impande za ihuriro rya karuboni na karuboni biganisha kuri aside asetiki aho kuba ibindi bicuruzwa.”
Uburyo bwa Senftle n'ikipe ye bwo kubara bwafashije kunoza imiterere y'iki gikoresho. Yagize ati: “Turashobora kwerekana ubwoko bw'inkombe kuri iki gikoresho, ahanini ari ubuso bunini. Bifasha guca imfunguzo zimwe na zimwe za CO, kugira ngo ibicuruzwa bishobore gukoreshwa mu buryo bumwe cyangwa ubundi.” Ahantu henshi ho guca impembe bifasha guca imfungano ikwiye mu gihe gikwiye.”
Senftler yavuze ko uyu mushinga ari ikimenyetso cyiza cy'uburyo inyigisho n'igerageza bigomba guhuzwa. Yagize ati: “Kuva ku guhuza ibice biri muri reactor kugeza ku rwego rwa atome, uru ni urugero rwiza rw'urwego rwinshi rw'ubuhanga.” “Ujyanye n'insanganyamatsiko ya nanotechnology ya molekile kandi ugaragaza uburyo dushobora kuyigeza ku bikoresho bifatika.”
Wang yavuze ko intambwe ikurikira mu iterambere rya sisitemu ishobora kwaguka ari ukunoza umutekano wa sisitemu no kugabanya ingufu zikenewe muri icyo gikorwa.
Abanyeshuri barangije muri Kaminuza ya Rice, Zhu Peng, Liu Chunyan na Xia Chuan, J. Evans Attwell-Welch, umushakashatsi wa postdoctoral, ni we muntu mukuru ushinzwe iyi nyandiko.
