Kawanishi, Japan, Nov. 15, 2022 /PRNewswire/ — Makani aabusena mbuli kuchincha kwachiimo chamulengalenga, kumana kwazintu zyabulenge, kuzimaana kwamisyobo yazilenge, kusofwaazyigwa kwamapulasitiki akugonkwa kwamasyokwe zilikuyaabuvwula nyika yoonse akaambo kakuvwula kwabantu.
Muya uutegwa carbon dioxide (CO2) muya uusofweede mpawo ngumwi wazintu zipa kuti kube kuchincha kwachiimo chamulengalenga. Muleezi, nzila iizyibidwe kuti "kupangwa kwamumuni (kucheya kwa CO2)" ilakonzya kupanga zintu zipona zyakupanga mafuta amakemikalu kuzwa ku CO2, maanzi anguzu zyazuba, mbweenya mbuli zisyango mbozichita. Aawo awo, zilagwisya CO2, nkaambo CO2 ilabelesyegwa mbuli chintu chakupanga manguzu azintu zyamakemikalu. Aboobo, nzila yakupanga zuba iipangidwe abantu ilabonwa kuti ninzila imwi mpya yakukwabilila buumi.
Ma MOFs (Metal Organic Frameworks) nzintu zijisi mapopwe manji kapati zipangidwe aamabwe aatakwe buumi alimwi azintu zijatikizya zintu zipona. Zilakonzya kweendelezyegwa aama molecule aali mu nanometer range mpawo zilaa busena bupati. Akaambo kazyintu eezyi, ma MOF alakonzya kubelesegwa mukubamba muya, kwaandaanya, kuyobola nsimbi, kugwasya, kutola misamu, kusalazya maanzi, zibelesyo zyakumvwa, ma electrode, ma filter, azimwi. Ino-ino, ma MOF akajanwa kuti alakonzya kujata CO2 aakonzya kuchesya CO2, nkokuti, kupanga mumuni.
Madoti aa quantum, kulubazu lumwi, nzintu ziteteete kapati (0.5–9 nm) eezyo ziboneka zyeendelana amilawu ya quantum chemistry antoomwe a quantum mechanics. Ziitwa kuti "ma atomu aapangidwe naa ma molecule aapangidwe" nkaambo doti lyomwe lyomwe lilijisi buyo zyuulu zisyoonto zya atomu naa ma molecule. Muchiimo eechi, nguzu zyama electron tazichizumanani pe mpawo zilaandaana akaambo kachintu chilibonya chiitwa kuti quantum confinement effect. Muchiimo eechi, bulamfwu bwamumuni uuzwa buyooyeeme abupati bwama doti aa quantum. Aaya ma doti aa quantum alakonzya kubelesegwa mukupanga mumuni akaambo kakukonzya kwawo kuyobola mumuni, alakonzya kupanga ma exciton miingi antoomwe abusena bupati.
Zyoonse zyobile MOFs ama quantum dots zyakabambwa aansi aa Green Science Alliance. Chiindi, bakazwidilila kubelesya MOF quantum dot composite materials kupanga fomic acid mbuli chintu chigwasya kupanga zuba. Nokuba boobo, aaya ma catalysts ali muchimo cha busi mpawo aaya ma catalyst powder ayelede kuyobolwa kwiinda mukusefa munzila imwi aimwi. Aboobo, mbwaanga nzila eezyi tazizumanani pe, zilakatazya kuzibelesya mumakkampani.
Mukwiingula, ba Tetsuro Kajino, ba Hirohisa Iwabayashi, a Dr. Ryohei Mori baku Green Science Alliance Co., Ltd. bakabelesya minchina yabo kuti bachinche zintu eezyi zipa kuti kube kupanga mumuni mumapepa aataduli mpawo bakapanga nzila mpya yakupanga asidi. eeyo iikonzya kubeleka lyoonse mumilimo yamakkampani. Nikwamana kuchitwa kwakupanga mumuni, maanzi ajisi asidi yafoomu alakonzya kugwisigwa kuti agwisyigwe, mpawo maanzi mapya alakonzya kujokezyegwa muchikombe kuti kuzumanane kupanga mumuni.
Asidi yafoomu ilakonzya kunjila mubusena bwamafuta aa haayidirojeni. Chimwi chazintu zipati zilesya kumwaika kwa mbunga ya haayidirojeni munyika yoonse nkakuti haayidirojeni ni atomu nsyoonto kwiinda yoonse mububumbo boonse, aboobo nkuyumu kwiibamba, mpawo kupanga tanki lya haayidirojeni lijisi nguzu zyakujala loko kuyoodula loko. Mukuyungizya, muya wa haayidirojeni ulakonzya kubboloka mpawo ulakonzya kuleta ntenda. Mbwaanga asidi yafoomu nchintu chiyumu, nchuubauba kuyobola mbuli mafuta. Kuti kakuli kuyandika, asidi yafoomu ilakonzya kubelesegwa kugwasya kupanga haayidirojeni mubusena. Mukuyungizya, asidi yafoomu ilakonzya kubelesegwa mbuli chintu chakupanga makemikalu aasiyene.
Nikuba kuti bubotu bwakupanga mumuni buli munsi, mbunga ya Green Science Alliance iyoozumanana kulwana kuti kube kuyaambele kwakubeleka kabotu kutegwa kube nzila zigwasya zyakupanga mumuni.
