Tekinologiya ensya ey’okushemeza neereetera okushemererwa kw’okushemeza kuba okw’omugasho. 1449240174198-2′);});
Bainginiya aha yunivasite ya Rice nibahindura butoosha carbon monoxide kuba acetic acid (omubazi ogurikukoresibwa munonga ogurikuha vinegar okushemererwa kw’amaani) kurabira omu kikwato ekirikuguma nikihindura, ekirikubaasa kukoresa gye amashanyarazi agarikugarukaho kureetaho ebintu ebishemeire munonga .
Enkora y’amashanyarazi omu laboratory y’abanyabwengye omu by’emibazi n’ebintu ebiine amagara aha ishomero rya Brown erya Rice University, eshobooroire ekizibu ekyabaireho enyima y’okugyezaho kukyendeeza omuyaga gwa carbon monoxide (CO) kuhinduka acetic acid. Enkora ezi nizetenga amatembezo agandi kubaasa kushemeza ekintu.
Ekikwato eki ekitarikushiisha eby’obuhangwa nikikozesa copper ya nanometer cubic nk’ekintu kikuru ekirikureetaho amashanyarazi kandi n’ekintu ky’omutaano ekigumire.
Omu shaaha 150 z’okukora omu laboratory okutarikuhwaho, ebiriisa bya acetic acid omu nshaho y’amaizi eyaabaire neeruga omu kikwato eki bikaba biri kuhika ahari 2%. Obushemeire bw’ekicweka kya asidi nibuhika ahari 98%, ekirikukira munonga ekicweka kya asidi ekirikuruga omu kugyezaho kwa kare okuhindura carbon monoxide kuba amajuta g’amaizi.
Acetic acid neekoresibwa nk’ekintu ekirikurinda eby’okurya omu by’obujanjabi hamwe na vinegar n’ebindi by’okurya. Nikikozesibwa nk’ekirungo ky’okusiiga erangi, erangi n’ebintu ebirikugijwara; omu kukora vinyl acetate, vinyl acetate niyo erikubanza omu glue erikwera eya buriijo.
Omuringo gwa Rice nigurugiirira aha kikwato ekirikukora omu laboratory ya Wang kandi nikikora formic acid kuruga omu mwanya ogurikwetwa carbon dioxide (CO2). Okucondooza oku kukataho omusingi mukuru ahari Wang (owaaheza kutooranwa kuba Packard Fellow), owatungire obuhwezi bwa miriyooni 2 eza doola kuruga omukitongore kya National Science Foundation (NSF) kugumizamu naacondooza emiringo y’okuhindura ebiriisa by’omuyaga kuba amajuta g’amaizi.
Wang akagira ati: “Nitutunguura ebintu byaitu kuruga aha mubazi ogurimu kaboni emwe ogwa formic acid kuza aha mubazi ogurimu kaboni ibiri, ekirikukirayo kugumira.” “Abantu omu buhangwa bwabo nibakora acetic acid omu bishaju by’amaizi, kwonka nabwo nibikora kubi kandi ebirikurugamu ni Ekizibu ky’okwahukana kw’eby’amashanyarazi.”
Senftle akongyeraho ati: “Buzima, obwire obwingi acetic acid terikukorwa kuruga omu CO nari CO2.” “Egi niyo nshonga: nitunywanisa omuyaga ogu turikwenda kukyendeeza kandi tukaguhindura ebintu by’omugasho.”
Okuteerana kw’obwegyendesereza kukakorwa ahagati y’ekirungo ky’omuringa n’ekirungo ky’amashanyarazi ekigumire, kandi ekirungo ky’amashanyarazi ekigumire kikatwarwa kuruga omu kirungo ky’amashanyarazi ekya formic acid. Wang akagira ati: “Obwire obumwe copper neija kureetaho emibazi omu mihanda ebiri etarikushushana.” "Nikibaasa kukyendeeza omuyaga gwa carbon monoxide kuhinduka asidi ya asidi n'omwengye. Tukakora ekicupuri ekiine amaisho ekirikubaasa kutegyeka okuteerana kwa kaboni na kaboni, n'empimbi za kaboni na kaboni Okuteerana nikureetaho asidi ya asidi okukira ebindi bintu."
Senftle n’omuringo gw’okubara ogwa tiimu ye bakahwera omu kuboneza enkora ya cube. Akagira ati: “Nitubaasa kworeka omuringo gw’empimbi eziri aha kicupuri, ezirikukirayo kuba zirimu ebicupuri. Nizihwera kuhenda ebishumuruzo ebimwe ebya CO, kugira ngu ekintu ekyo kibaasa kuhindurwa omu muringo gumwe nari ogundi.” Emyanya endiijo ey’aha rubaju neehwera kuhenda omukago oguhikire omu bwire obuhikire.”
Senftler agizire ngu purojekiti egi n’okworeka kurungi oku enteekateeka n’okugyezesa biine kukwatiraine. Akagira ati: “Kuruga aha kugaita ebicweka ebiri omu kikwato eki kuhika aha nkora eri aha rurengo rwa atomu, eki n’eky’okureeberaho kirungi ky’emiringo mingi y’eby’obuhangwa.” “Nikihikaana n’omutwe gwa molecular nanotechnology kandi nikyoreka oku turikubaasa kukijanjaaza aha bikwato by’omu nsi buzima.”
Wang agizire ngu eitembezo erikukurataho omukukora enkora erikubaasa kugyezesibwa n’okutunguura okuhama kw’enkora n’okwongyera kukyendeeza amaani agarikwetengyesa omu nkora egi.
