Ico gikoresho gishasha c’inzobe gituma uburyohe bw’umunyu bugira ico bukoze. 1449240174198-2 ');});
Abahinga bo muri kaminuza ya Rice bariko barahindura ata guca ku ruhande umuyagankuba w’umuyagankuba ngo ube aside acetique (ikintu gikoreshwa cane gituma inkari igira akamoto gakomeye) biciye ku gikoresho gikomeza gutuma umuyagankuba ukora neza, kikaba gishobora gukoresha neza umuyagankuba ushobora gusubirwamwo kugira ngo gikoreshe ibintu vyiza cane .
Ivyo bikoresho vy’ubuhinga bw’amashanyarazi bikoreshwa mu laboratwari y’abahinga mu vy’ubuhinga bw’imiti n’ivy’ibinyabuzima vyo mw’ishure ry’ubuhinga ryitwa Brown School of Engineering ryo muri kaminuza ya Rice, vyatorera umuti ingorane y’ukugerageza kwa kera kwo kugabanya umuyagankuba (CO) ngo ube aside acetique. Ivyo bikorwa bisaba intambwe z’inyongera kugira ngo ico kintu gisukurwe.
Ico gikoresho kidahungabanya ibidukikije gikoresha umuringa w’uburebure bwa nanometer nk’ikintu nyamukuru gitera umuriro be n’umuyagankuba ukomeye udasanzwe.
Mu masaha 150 y’ibikorwa vya laboratwari bikomeza, aside acetique iri mu mazi yasohotse n’ico gikoresho yari ishika kuri 2%. Ubusuku bw’igice c’aside burashika ku bice 98 kw’ijana, ivyo bikaba ari vyiza cane kuruta igice c’aside giterwa n’ukugerageza kwa mbere guhindura umuyagankuba w’amazi (carbone monoxide) ngo ube igitoro c’amazi.
Asidi asetike ikoreshwa nk’ikintu co kuzigama mu bikorwa vy’ubuvuzi hamwe n’inkari n’ibindi biryo. Ikoreshwa nk’ikintu co gusukura amarangi, amarangi n’ibindi bikoresho; mu guhingura ivyuma vy’ivyuma, ivyuma vy’ivyuma ni vyo bibanza gukora ivyuma vyera bisanzwe.
Ivyo bikoresho vy’umuceri bishingiye ku gikoresho co mu laboratwari ca Wang, kikaba gikora aside formique iva mu mwuka w’ikirere (CO2). Ubwo bushakashatsi bwashizeho umushinge uhambaye kuri Wang (aherutse gutorwa ngo abe umugenzi wa Packard), yaronse ingurane y’amadolari imiliyoni zibiri y’ishirahamwe ry’igihugu ry’ubuhinga (NSF) kugira ngo abandanye arondera uburyo bwo guhindura imyuka itera ibidukikije ngo ibe amazi.
Wang yavuze ati: “Turiko turahindura ibintu vyacu tukava ku kintu kimwe c’imiti gifise carbone imwe ari co aside formique tukaja ku kintu c’imiti gifise carbone zibiri, ivyo bikaba bitoroshe kuruta.” “Abantu mu migenzo yabo barahingura aside acetique mu bihimba vy’umubiri bifise amazi, ariko biracari bifise ubushobozi buke kandi ivyo bihimba ni Ikibazo co gutandukanya ibihimba vy’umubiri.”
Senftle yongeyeko ati: “Ego ni ko, akenshi aside asetike ntiyinjira mu CO canke CO2.” “Iki ni co ciyumviro: turiko turanywa gazi y’umwanda twipfuza kugabanya maze tukayihindura ibintu vy’ingirakamaro.”
Haciye hakorwa ugufatanya kw’ubwitonzi hagati y’igikoresho co gutuma umuringa ukora neza n’ico gikoresho gikomeye, maze ico gikoresho gikomeye kigakurwa mu gikoresho gikorana n’aside formique. Wang yavuze ati: “Rimwe na rimwe umuringa uzotuma haba imiti mu nzira zibiri zitandukanye.” "Bishobora kugabanya umwuka w'ikirere ukagira aside asetike n'inzoga. Twarahinguye ikibumbano gifise mu maso gishobora kugenzura ukuntu umuyagankuba n'umuyagankuba bifatanya, n'imirongo y'umuyagankuba n'umuyagankuba Uwo muyagankuba utuma habaho aside asetike aho gushika ku bindi bintu."
Senftle n’umugwi wiwe w’ubuhinga bwo guharura barafashije mu gutunganya uburyo iyo cube iteye. Yavuze ati: "Turashobora kwerekana ubwoko bw'imirongo iri kuri iyo cube, iyo na yo ikaba ari imirongo myinshi cane. Bifasha guca imfunguruzo zimwezimwe za CO, kugira ngo ico kintu gishobore gukoreshwa mu buryo bumwe canke ubundi." Ibindi bibanza vyo ku ruhande birafasha guca ubucuti bubereye ku gihe kibereye.”
Senftler yavuze ko uwo mugambi ari ikimenyetso ciza c’ingene inyigisho n’igerageza bikwiye guhurizwa hamwe. Yavuze ati: “Kuva ku gushiramwo ibihimba biri muri iyo reactor gushika ku buryo bukora ku rugero rw’atome, aka ni akarorero keza k’urugero rwinshi rw’ubuhinga.” “Irahuye n’insanganyamatsiko y’ubuhinga bwa nano bw’ibihimba vy’umubiri kandi yerekana ingene twoshobora kubushira ku bikoresho vy’ukuri.”
Wang yavuze ko intambwe ikurikira mu gutegura ubuhinga bushobora guhindurwa ari ugutuma ubuhinga buguma buhagaze neza no kurushiriza kugabanya inguvu zikenewe kugira ngo iyo nzira ikore.
Abanyeshure bo muri kaminuza ya Rice, Zhu Peng, Liu Chunyan na Xia Chuan, J. Evans Attwell-Welch, umushakashatsi w’inyuma y’amashure yisumbuye, ni we muntu nyamukuru ashinzwe ico cegeranyo.
Ushobora kwizigira ko abakozi bacu b’abanyamakuru bazokurikiranira hafi inyishu yose yoherejwe kandi bazogira ico bakoze bikwiye. Iciyumviro cawe kiradufasha cane.
