Umthamo wentlawulo aI-electrode yebhetri ye-lithium-ion eprintiweyo ye-3D, engaphezulu ngokuphindwe kathathu ukuphakama kwe-electrode eyenziwe ngokuqhelekileyo.Ubuchule bokushicilela be-3D bulungelelanisa i-graphite nanoflakes kwizinto eziphathekayo ukuze kulungiswe ukuhamba kwee-ion ze-lithium ngaphakathi nangaphandle kwe-electrode (uphando oluchazwe kwintlanganiso ye-ACS Spring 2022).

Ukusebenza kakuhle aiseli yelanga ye-perovskiteingxelo kwi-2022, ibeka irekhodi ye-flexible thin-film photovoltaics.Ukusebenza kakuhle kweseli ye-tandem ekujikeni ukukhanya kwelanga kube ngumbane kubetha umnini werekhodi wangaphambili ngeepesenti ezi-3 kwaye inokumelana nokugoba kwe-10,000 ngaphandle kwelahleko ekusebenzeni (Nat.Amandla2022, DOI:10.1038/s41560-022-01045-2).

Umlinganiselo wokuba iisixhobo se-electrodialysisibamba ikharbon diokside xa ithelekiswa neenkqubo zangoku zokubamba ikharbhon.Abaphandi babale ukuba inkqubo enkulu enokuthi ibambe i-1,000 yeetoni ze-metric ye-CO2 ngeyure iya kuxabisa i-$ 145 ngetoni nganye ye-metric, ngaphantsi kwexabiso leSebe lezaMandla elijoliswe kwi-200 ye-metric toni yeetekhnoloji zokususwa kwekhabhoni.Amandla okusingqongileyo.Sci.2022, DOI:10.1039/d1ee03018c).

Inani leminyaka eyadlulayo ukuba umsebenzi weTectonic weplate yomhlaba kusenokwenzeka ukuba waqala, ngokutshouhlalutyo lwe-isotopic yeekristale ze-zirconeyavela ngelo xesha.Iikristale, eziqokelelwe kwibhedi yelitye lentlabathi eMzantsi Afrika, zibonisa utyikityo olufana nezo zenziwa kwiindawo zokuthotywa, ngelixa iikristale ezindala azibonakali (I-AGU Adv.2022, DOI:10.1029/2021AV000520).
