Bainjiniya baku Yunivesiti yaku Rice bali mukusandula muya uutegwa carbon monoxide kuba acetic acid (musamu uubelesyegwa kapati uupa kuti vinegar kibe aabubotu) kwiinda mukubelesya nzila iizumanana kubelesya magesi aakonzya kubelesegwa lubo kupanga zintu zisalala loko.
Nzila yakubelesya magesi mu laboratory yaba injiniya ba chemical a biomolecular ku Rice University's Brown School of Engineering yakamanizya penzi lyakusola kwakaindide kucesya carbon monoxide (CO) kuba acetic acid. Nzila eezi ziyanda ntaamu zimbi zyakusalazya chintu.
Ibbazu litanyonganyi busena libelesya nanometer cubic copper mbuli chintu chipati chipa kuti kube magesi mpawo nchintu chiyumu chilibedelede.
Mumawoola aali 150 aakuzumanana kubeleka mu laboratory, asidi ya acetic mumusamu wamaanzi wakapangwa aachibelesyo eechi yakasika ku 2%. Busalali bwacibeela ca asidi bulasika ku 98%, oobo buli kabotu kwiinda cibeela ca asidi cipangwa akusola kwakusaanguna kusandula carbon monoxide kuba mafuta aajisi maanzi.
Acetic acid ibelesyegwa mbuli chintu chikwabilila zyakulya mubusilisi antoomwe a vinegar azimwi zyakulya. Ibelesyegwa mbuli chintu chakusanzya ingi, penti azintu zyakuvwumba; mukupanga vinyl acetate, vinyl acetate ninzila yakusaanguna ya glue iituba.
Nzila ya Rice iyeeme aa reactor iili mu laboratory ya Wang mpawo ilapanga asidi kuzwa ku carbon dioxide (CO2). Ooku kuvwuntauzya kwakabikka ntalisyo iiyandika kuli Wang (wakasalwa lino-lino kuba Packard Fellow), walo wakatambula lugwasyo lwamali aasika ku $2 miliyoni kuzwa ku National Science Foundation (NSF) kuti azumanane kuyandaula nzila zyakusandula muya uusofweede kuba mafuta.
Wang wakati: "Tuli mukusumpula zintu zyesu kuzwa ku kaboni yomwe ya formic acid kuya ku kaboni zyobile, eecho nchintu chiyumu." "Bantu balapanga acetic acid muma electrolyte aali mumaanzi, pesi tabakonzyi kubeleka kabotu mpawo zintu eezyo zili penzi lyakuandaanya ma electrolyte."
Senftle wakayungizya: "Masimpe, acetic acid kanjikanji taipangwi kuzwa ku CO naa CO2." "Aaka nkakaambo: tulikunywa muya uusofweede ngotuyanda kuchesya mpawo tuwusandula kuba zintu zigwasya."
Kuswaangana kwakachitwa aakati ka copper catalyst a electrolyte, mpawo electrolyte yakagwisigwa kuzwa ku formic acid reactor. Wang wakati: "Chimwi chiindi mukuba ulakonzya kupanga makemikalu munzila zyobile zisiyene." "Chilakonzya kuchesya kaboni monokisayidi kuba asiti asidi a bukoko. Twakapanga kabbokesi kajisi busyu bukonzya kweendelezya kujatana kwa kaboni-kaboni, mpawo mibalo ya kaboni-kaboni Kuswaangana ooku kusololela ku asitiki asidi kutali zimwi zintu."
Senftle abamwi bakwe nzila yakubelesya kkompiyuta yakagwasya kubambulula chiimo cha cube. Wakati: "Tulakonzya kutondezya musyobo wamagolelo aa cube, alo aali atala aajisi mabwe. Agwasya kutyola makkii amwi aa CO, kuchitila kuti chintu chibelesyegwe munzila imwi." Masena manji aali afwaafwi alagwasya kutyola chilongwe chili kabotu muchiindi cheelede.
Senftler wakati pulojekiti eeyi nchitondezyo chibotu chakuti njiisyo akusola zyeelede kuswaangana biyeni. Wakati: "Kuzwa kukuswaanganya zibeela zya reactor kusikila kunzila ya atomu, eechi nchikozyano chibotu chazibeela zyiingi zya injiniya." "Cileendelana amutwe wamakani wa molecule nanotechnology mpawo chitondezya mbutukonzya kuchiyungizya kuzibelesyo ziliwo ncobeni."
Wang wakaamba kuti ntaamu itobela mukupanga nzila iikonzya kuyaambele nkusumpula kukkalikana kwanzila eeyi akuyungizya manguzu aayandika mumulimo ooyu.
Basicikolo bakamanizya chikolo ku Yunivesiti yaku Rice Zhu Peng, Liu Chunyan a Xia Chuan, J. Evans Attwell-Welch, sikuvwuntauzya wamamanino, ngomuntu mupati weendelezya pepa eeli.
