Umthamo wokutshaja weI-electrode yebhetri ye-lithium-ion eprintiweyo nge-3D, ephindwe kathathu kunowe-electrode eyenziwe ngendlela eqhelekileyo. Le ndlela yokuprinta ye-3D ilungelelanisa ii-nanoflakes ze-graphite kwizinto ukuze kuphuculwe ukuhamba kwee-ion ze-lithium ngaphakathi nangaphandle kwe-electrode (uphando luxelwe kwintlanganiso ye-ACS Spring 2022).

Ukwanda komsebenzi wei-enzyme entsha eyenziwe ngobunjinelieyonakalisa i-polyethylene terephthalate (PET) xa ithelekiswa ne-PETases zangaphambili. Le enzyme yahlulahlula iisampulu ze-PET ezingama-51 ezahlukeneyo ngokuhamba kwexesha ukusuka kwiiyure ukuya kwiiveki (Indalo2022, DOI:10.1038/s41586-022-04599-z).

Ukusebenza kakuhle kweiseli yelanga ye-perovskiteingxelo ngo-2022, ibeka irekhodi ye-flexible thin-film photovoltaics. Ukusebenza kakuhle kwe-tandem cell ekuguquleni ukukhanya kwelanga kube ngumbane koyisa umnini werekhodi wangaphambili ngamanqaku ama-3 eepesenti kwaye inokumelana nokugoba kwe-10,000 ngaphandle kokulahlekelwa kukusebenza (Amandla eNat2022, DOI:10.1038/s41560-022-01045-2).

Izihlandlo ezili-100

Izinga lokubaisixhobo se-electrodialysisibamba ikharbon diokside xa ithelekiswa neenkqubo zangoku zokubamba ikharbon. Abaphandi babala ukuba inkqubo enkulu enokubamba iitoni ze-CO2 ezili-1,000 ngeyure iya kubiza i-$145 ngetoni nganye, ngaphantsi kwexabiso elijoliswe kwiSebe lezaMandla le-$200 ngetoni nganye ye-metric kwiiteknoloji zokususa ikharbon (Indalo yamandla. Isayensi.2022, DOI:10.1039/d1ee03018c).

Ipesenti yee-molecule ze-hydrocarbon ezinobukhulu bepetroli ezivunyelweyo nge-ainwebu yepolymerI-membrane inokumelana namaqondo obushushu aphezulu kunye neemeko ezinzima kwaye inokubonelela ngendlela engadingi mandla amaninzi yokwahlula ipetroli kwi-oyile ekrwada ekhaphukhaphu (Isayensi2022, DOI:10.1126/science.abm7686).

Iibhiliyoni ezi-3.8

Kwiminyaka eyadlulayo apho umsebenzi we-tectonic weplate yoMhlaba kusenokwenzeka ukuba waqala khona, ngokutsho kwe-anUhlalutyo lwe-isotopic lweekristale ze-zirconezadalwa ngelo xesha. Iikristale, eziqokelelwe kwindawo yesanti eMzantsi Afrika, zibonisa iimpawu ezifana nezo zenziwe kwiindawo ezingaphantsi, ngelixa iikristale ezindala zingabonakali (Umcebisi we-AGU.2022, DOI:10.1029/2021AV000520).

Ipesenti yokukhanya kwelanga okubonakaliswa yi-ipeyinti emhlophe okwesibhakabhakaequlethe iiplatelets ze-boron nitride ezineehexagonal. Umbala wepeyinti obunzima obuyi-150 µm ungapholisa umphezulu nge-5–6 °C elangeni ngqo kwaye unokunceda ekunciphiseni amandla afunekayo ukugcina iinqwelomoya kunye neemoto zipholile (Ingcali yeSayensi yoMmeli weSeli.2022, DOI:10.1016/j.xcrp.2022.101058).

Ukwehla kwepesenti kwiUsulelo lwe-SARS-CoV-2kwimizuzu engama-20 emva kokuba intsholongwane ifumene umoya wangaphakathi. Abaphandi bafumanise ukuba ubomi bentsholongwane ye-COVID-19 buchaphazeleka kakhulu lutshintsho kumswakama othelekisekayo (IProc. Natl. Acad. Sci. USA2022, DOI:10.1073/pnas.2200109119).
