Ulusi umenewu ukhoza kutsukidwa ndi kupakidwa utoto
Gulu la asayansi aku China lapanga ulusi wokhala ndi ulusi wotentha kwambiri womwe umalimbikitsidwa ndi ubweya wa chimbalangondo cha polar, Xinhua ikutero. Malinga ndi kafukufuku yemwe adasindikizidwa mu nyuzipepala ya Science, ulusi wa airgel uwu ndi wotha kuchapa, utoto, wokhazikika ndipo ungagwiritsidwe ntchito munsalu zamakono.
Ulusi wa Airgel nthawi zambiri umakhala wopanda mphamvu komanso wotambasulidwa wofunikira kuti alukidwe munsalu ndikutaya mphamvu zake zoziziritsa kukhosi pamvula kapena chinyezi. Komabe, ofufuza a ku yunivesite ya Zhejiang adalimbikitsidwa ndi ubweya wapadera wa zimbalangondo, zomwe zimapangitsa kuti zikhale zofunda komanso zowuma. Malinga ndi kafukufukuyu, tsitsi laubweya lili ndi porous core lomwe lili mkati mwa kachimake.
Potengera mmene tsitsi la chimbalangondo limapangidwira, ofufuzawo anapanga ulusi wolimba kwambiri wa airgel wokhala ndi timabowo tomwe timatchingira kuwala kwa dzuwa pafupi ndi khungu komanso kuti ukhale wolimba, kuti ukhale woyenerera kuluka kapena kuwomba.
Malinga ndi kafukufukuyu, ulusiwo umasungabe mphamvu zake zotchinjiriza ndikusintha pang'ono ngakhale pambuyo pa 10,000 mobwerezabwereza yotambasula pa 100 peresenti pokweza. Gulu lofufuzalo linayesa ulusiwo mu juzi lopyapyala, lomwe, ngakhale lili pafupifupi gawo limodzi mwa magawo asanu a makulidwe a jekete yapansi, lili ndi mphamvu zotsekereza zomwe zimafanana ndi jekete yokhuthala.
Malinga ndi ochita kafukufuku, kavalidwe "chochepa" kameneka kamapereka mwayi wochuluka wopangira ulusi wa airgel ndi nsalu zambiri m'tsogolomu.
