Monga mbali ziwiri za nano-material, graphene imakhala ndi thupi komanso mankhwala. Ndi nano-material yowonda kwambiri koma yovuta kwambiri yopezedwa ndi anthu pakali pano. Kulimba kwake kumaposa 200 kuposa chitsulo. Ili ndi mphamvu zabwino kwambiri zamagetsi ndi kuwala, ndipo resistivity yake ndi 10-6 chabe_.· M, ndi zinthu zotsika kwambiri za resistivity padziko lapansi pakalipano; imakhala ndi matenthedwe abwino, okhala ndi matenthedwe a 5300 W / (mK) kutentha kwa firiji, ndipo yadutsa malire a isomorphic bulk graphite, carbon nanotubes ndi diamondi, kupitirira kwambiri zipangizo zachitsulo monga siliva ndi mkuwa; ili ndi zochitika zapamwamba kwambiri, zotsatsa bwino kwambiri ndipo zimayerekeza kuyamwa kutsogolera kwa 800. Mg/g, apamwamba kwambiri kuposa activated carbon.

Graphene, monga chinthu chosinthika kwambiri cha "chilengedwe chonse", chingagwiritsidwe ntchito popanga maselo a dzuwa, zida za thupi, zida zowonera usiku, etc. Posachedwapa, kafukufuku wa Brown University ku United States amasonyeza kuti graphene oxide, yochokera ku graphene, ilinso ndi zotsatira zothamangitsa udzudzu, pamene woyesa amaphimba khungu ndi filimu yowonda ya graphene oxide. Pambuyo pa filimuyo, zinapezeka kuti udzudzu wochepa umakhala kunja kwa filimu youma ya graphene oxide. Ngakhale udzudzu utakhalapo, zingakhale zovuta kulowa mufilimu ya graphene oxide. Izi zikutanthauza kuti graphene okusayidi akhoza kukhala chotchinga kusokoneza udzudzu.

Ndizofunikira kudziwa kuti udzudzu ukadazindikira malo omwe chandamalecho pozindikira kapangidwe kake ka khungu la munthu, koma woyesayo atakulunga zovala ndi graphene oxide, udzudzu sunangoluma khungu lotetezedwa, komanso kuluma khungu lowonekera

"Tinkaganiza kuti graphene oxide ndi chotchinga chakuthupi chomwe chimalepheretsa udzudzu kuluma, koma titamaliza kuyesaku, tidayamba kuganiza kuti graphene oxide inalinso chotchinga chamankhwala chomwe chimalepheretsa udzudzu kumva kukhalapo kwa munthu," adatero Cintia Castilho, wolemba wamkulu. wa phunziroli ndi wophunzira wa Dr. Brown.

William Suk wa NIEHS Superfund Research Programme Doctor ananena kuti zimene apeza pa kafukufukuyu zingapangitse kuti pakhale zovala zatsopano zoteteza udzudzu, kuti anthu okhala m’madera otentha athe kuchepetsa mwayi wa matenda opatsirana obwera chifukwa cha udzudzu, monga matenda a dengue fever. Encephalitis ya ku Japan, ndi zina zotero, komanso kuchepetsa kuchuluka kwa mankhwala oletsa udzudzu omwe amagwiritsidwa ntchito, popanda kukhudza dongosolo la mitsempha chifukwa cha kupopera mankhwala kwambiri.
