Amandla wokushaja aI-electrode yebhethri ye-lithium-ion ephrintiwe ye-3D, ephakeme ngokuphindwe kathathu kune-electrode eyenziwe ngokujwayelekile.Isu lokuphrinta le-3D liqondanisa ama-graphite nanoflakes kokubalulekile ukuze kuthuthukiswe ukugeleza kwama-ion e-lithium ukungena nokuphuma ku-electrode (ucwaningo olubikwe emhlanganweni we-ACS Spring 2022).

Ukusebenza kahle kwe-aperovskite solar cellkubikwe ngo-2022, kusetha irekhodi lama-photovoltaics athambile wefilimu eguquguqukayo.Ukusebenza kahle kwe-tandem cell ekuguquleni ukukhanya kwelanga kube ugesi kwehlula umnikazi werekhodi wangaphambili ngamaphesenti angu-3 futhi ingamelana nokugoba okungu-10,000 ngaphandle kokulahlekelwa ekusebenzeni (Nat.Amandla2022, DOI:10.1038/s41560-022-01045-2).

Izinga ukuthi iidivayisi ye-electrodialysisibamba isikhutha uma iqhathaniswa nezinhlelo zamanje zokubamba ikhabhoni.Abacwaningi babale ukuthi uhlelo olukhulu olungabamba amathani angu-1,000 wemethrikhi ye-CO2 ngehora lungabiza u-$145 ton ngayinye yemethrikhi, ngaphansi kwezindleko ezihlosiwe zoMnyango Wezamandla zama-$200 toni ngayinye yemethrikhi yobuchwepheshe bokususa ikhabhoni (I-Energy Environ.Isayensi.2022, DOI:10.1039/d1ee03018c).

Inani leminyaka edlule lapho umsebenzi we-tectonic wepuleti lomhlaba cishe waqala, ngokusho kwe-ukuhlaziywa kwe-isotopic kwamakristalu e-zirconezakheka ngaleso sikhathi.Amakristalu, aqoqwe embhedeni we-sandstone eNingizimu Afrika, akhombisa amasiginesha afana nalawo akhiwe ezindaweni ezincishisiwe, kanti amakristalu amadala awanawo (I-AGU Adv.2022, DOI:10.1029/2021AV000520).
