Abaphandi baseJamani baye babika kwinqaku lamva nje lejenali yase-UK yeNdalo ukuba baye baphuhlisa inkqubo entsha yokunyibilikisa i-alloy enokuguqula ii-oxide zetsimbi eziqinileyo zibe yi-alloys emise okwebhloko kwinqanaba elinye. Iteknoloji ayifuni ukunyibilika kunye nokuxuba isinyithi emva kokuba ikhutshwe, inceda ukunciphisa ukukhutshwa kwegesi ye-greenhouse kunye nokugcina amandla.

Abaphandi beMax Planck Institute for Sustainable Materials eJamani basebenzisa i-hydrogen endaweni yekhabhoni njenge-arhente yokunciphisa ukukhupha isinyithi kunye nokwenza i-alloy kumaqondo okushisa angaphantsi kwendawo yokunyibilika kwesinyithi, kwaye baye bavelisa ngempumelelo i-alloys ephantsi yokwandisa kwiimvavanyo. I-alloys ephantsi yokwandisa i-64% yensimbi kunye ne-36% ye-nickel, kwaye inokugcina umthamo wabo ngaphakathi kweqondo lokushisa elikhulu, okwenza ukuba isetyenziswe ngokubanzi kwishishini.

Abaphandi baxuba iioksidi ze-iron kunye ne-nickel kumlinganiselo ofunekayo kwi-alloys e-low-expansion alloys, bayigubungele ngokulinganayo nge-ball mill baze bayicinezele kwiikeyiki ezincinci ezingqukuva. Emva koko bafudumeza amaqebengwana kwiziko ukuya kutsho kuma-700 ngokukaCelsius baza bazisa ihydrogen. Iqondo lobushushu lalingekho phezulu ngokwaneleyo ukunyibilikisa i-iron okanye i-nickel, kodwa laliphezulu ngokwaneleyo ukunciphisa isinyithi. Uvavanyo lubonise ukuba i-processed block-shaped metal yayineempawu eziqhelekileyo zokwandiswa kwe-alloys eziphantsi kwaye zinezixhobo ezingcono zomatshini ngenxa yobukhulu bayo obuziinkozo. Ngenxa yokuba imveliso egqityiweyo yayikwimo yebhloko kunokuba i-powder okanye i-nanoparticles, kwakulula ukuyiphosa kunye nokusebenza.

Ukunyibilikiswa kwealloyi yesiNtu kubandakanya amanyathelo amathathu: okokuqala, ii-oxide zesinyithi kwintsimbi ekrwada zincitshiswa zibe yintsimbi ngekhabhoni, emva koko isinyithi sikhutshwa yikhabhoni kwaye isinyithi esahlukileyo siyanyibilika kwaye sixutywe, kwaye ekugqibeleni, ukusetyenzwa kwe-thermal-mechanical kuqhutywa ukulungelelanisa i-microstructure. i-alloy ukuyinika iimpawu ezithile. La manyathelo atya izixa ezikhulu zamandla, kwaye inkqubo yokusebenzisa ikharbon ukunciphisa isinyithi ivelisa izixa ezikhulu zekharbon diokside. Ukukhutshwa kwekhabhoni kushishino lwesinyithi kubalelwa kwi-10% yetotali yehlabathi.

Abaphandi bathi i-byproduct yokusebenzisa i-hydrogen ukunciphisa isinyithi ngamanzi, kunye nokukhutshwa kwekhabhoni, kwaye inkqubo elula inamandla amakhulu okonga amandla. Nangona kunjalo, iimvavanyo zasebenzisa i-oxides yentsimbi kunye ne-nickel yococeko oluphezulu, kunye nokusebenza kakuhle
