Ubushobozi bwo kwishyuza bwaElectrode ya bateri ya lithium-ion yacapwe mu buryo bwa 3D, ikaba ikubye inshuro eshatu uburebure bw'amashanyarazi asanzwe. Ubu buryo bwo gucapa bwa 3D buhuza nanoflakes za grafiti mu bikoresho kugira ngo burusheho gutembera neza kw'iyoni za lithiamu zinjira kandi zisohoka muri electrode (ubushakashatsi bwatanzwe mu nama ya ACS yo mu mpeshyi 2022).

Ukwiyongera k'ibikorwa byaenzyme nshya y'ubuhangabyangiza polyethylene terephthalate (PET) ugereranije na PETases zabanje. Iyi enzyme yakusanyije ingero 51 zitandukanye za PET mu gihe cy'amasaha kuva ku byumweru kugeza ku masaha (Kamere2022, DOI:10.1038/s41586-022-04599-z).

Ingufu zaselile y'izuba ya perovskitebyatangajwe mu 2022, bishyiraho agahigo ko guhindura urumuri rw'izuba mu buryo bworoshye. Ingufu z'aka karemangingo ka tandem mu guhindura urumuri rw'izuba mu buryo bw'amashanyarazi ziruta izari zifite agahigo ku kigero cya 3 ku ijana kandi zishobora kwihanganira imigozi 10.000 nta gihombo mu mikorere (Ingufu za Nat.2022, DOI:10.1038/s41560-022-01045-2).

Igipimo cy'ukoigikoresho cya elegitoronikiifata dioxyde de carbone ugereranije n'uburyo bwo gufata karubone buriho ubu. Abashakashatsi babaze ko uburyo bunini bushobora gufata toni 1.000 za CO2 ku isaha bwatwara $145 kuri toni, munsi y'intego ya Minisiteri y'Ingufu ya $200 kuri toni imwe mu ikoranabuhanga ryo gukuraho karubone (Ibidukikije by'ingufu. Siyansi.2022, DOI:10.1039/d1ee03018c).

Ijanisha ry'uturemangingo twa hydrocarboni ingano ya lisansi yemerewe binyuze muriururenda rwa polima. Uru rusobe rw'amavuta rushobora kwihanganira ubushyuhe bwinshi n'ibihe bikomeye kandi rushobora gutanga uburyo budakoresha ingufu nyinshi bwo gutandukanya lisansi n'amavuta yoroheje (Siyansi2022, DOI:10.1126/science.abm7686).

Hashize imyaka myinshi ibikorwa bya tectonic by'Isi bishoboka cyane ko byatangiye, nk'uko byagaragajwe n'umubareisesengura rya isotopi rya kristu za zirconbyaremwe icyo gihe. Amabuye yakusanyijwe mu butaka bw'amabuye y'umucanga muri Afurika y'Epfo, agaragaza ibimenyetso bisa n'ibyakozwe mu duce duto, mu gihe amabuye ya kera yo ntabyo (Adv. wa AGU.2022, DOI:10.1029/2021AV000520).

Igihe cyashize hagati yo gukora Cp* ligand ikozwe muri perfluorine no kuremwa kwayoihuriro rya mbere ry'imikoranire. Igerageza ryose ryabanje ryo guhuza ligand, [C5 (CF3)5]−, yari yarananiwe kubera ko amatsinda yayo ya CF3 arimo gukuramo electron cyane (Angew. Chemistry. Int. Ed.2022, DOI:10.1002/anie.202211147).

Ijanisha ry'izuba rigaragazwa n'izubairangi ry'umweru ukabijeirimo nanoplatelets za boron nitride zifite ubugari bwa hexagonal. Ibara rifite ubugari bwa µm 150 rishobora gukonjesha ubuso ku bushyuhe bwa 5–6 °C ku zuba ritaziguye kandi rishobora gufasha kugabanya ingufu zikenewe kugira ngo indege n'imodoka bikomeze gukonja (Ushinzwe Ubumenyi bw'Umwiherero mu by'Ubumenyi.2022, DOI:10.1016/j.xcrp.2022.101058).
