Utoto wagalimoto watsopano ukhoza kulowa m'malo oziziritsa mpweya

Utoto watsopano wopangidwa ndi asayansi ukhoza kupangitsa kuti mkati mwagalimoto muzizizira kwambiri ngakhale pakakhala kutentha kwambiri. Utoto womwewo ungagwiritsidwenso ntchito panyumba kapena nyumba.

Kusasowa galimoto, ngakhale kutentha kwa madigiri 100, kungakhale lingaliro labwino, ndipo ngakhale zikuwoneka zosatheka, zikhoza kukhala zenizeni. Njira yatsopano yopenta yomwe yangopangidwa kumene ingathandize kuti nyumba ndi magalimoto zisadalire kwambiri pakuwongolera mpweya..

Akatswiri opanga mayunivesite a Purdue apanga utoto wosintha. Ichi ndiye choyera kwambiri chomwe chinapangidwapo. Panopa ofufuza akuti kupaka utoto umenewu m’galimoto kapena m’nyumba kumachepetsa kufunika kwa mpweya woziziritsira mpweya.

Njira yopenta yoyera kwambiri imasunga chilichonse chomwe chapentidwa chozizira kwambiri

Mtundu wa utoto wonyezimira kwambiri wa Purdue umapangitsa chilichonse chopentidwa mwatsopano. "Mukadagwiritsa ntchito utoto uwu padenga lokhala ndi masikweya mita pafupifupi 1,000, tikuyerekeza kuti mutha kupeza ma kilowatts 10 oziziritsa," Xiuling Ruan, pulofesa waukadaulo wamakina ku Purdue, adauza Scitechdaily. "Izi ndi zamphamvu kwambiri kuposa ma air conditioners apakati omwe amagwiritsidwa ntchito m'nyumba zambiri," adatero.

Mwinamwake mukukumbukira Vantablack, utoto wakuda uja womwe umatenga 99% ya kuwala kowoneka. Chabwino, utoto woyera uwu ndi wosiyana kwambiri ndi Vantablack. Ndiko kuti, imawunikira 98.1% ya kuwala kwa dzuwa.

Zinatenga zaka zisanu ndi chimodzi za kafukufuku kuti apeze utoto woyera kwambiri. Kwenikweni, zimachokera ku kafukufuku wopangidwa mu 1970s.. Panthawiyo, kafukufuku anali mkati kuti apange utoto woziziritsa wa radioactive.

Kodi ntchito?

Kutentha kwa infrared kumachokera ku chilichonse chomwe chapakidwa utoto woyera. Izi ndizosiyana kwambiri ndi zomwe utoto woyera umachita. Kumatenthera m'malo mozizira pokhapokha ngati apangidwa kuti athetse kutentha.

Utoto woyera wopangidwa mwapadera uwu umangowonetsa 80-90% ya kuwala kwa dzuwa. Ndipo siiziziritsa pamwamba pomwe imakokedwapo. Izi zikutanthawuzanso kuti sizizizira zomwe zikuzungulira mtundu uwu wa utoto.

Ndiye nchiyani chomwe chimapangitsa woyera kwambiri uyu kukhala woyera modabwitsa? Ndi barium sulphate yomwe imawonjezera kuzizira kwake. Barium sulphate amagwiritsidwanso ntchito popanga pepala lojambula zithunzi, ndipo ndizomwe zimapangitsa zodzoladzola zina kukhala zoyera.

Kugwiritsa ntchito barium sulphate kumapangitsa kuti zinthu ziziwoneka bwino

"Tidayang'ana pazinthu zosiyanasiyana zamalonda, makamaka chilichonse chomwe chili choyera," adatero Xiangyu Li, Ph.D. ku Purdue. wophunzira mu labotale ya Rouen. "Tidapeza kuti pogwiritsa ntchito barium sulfate, mutha kupanga zinthu kukhala zowunikira kwambiri. Izi zikutanthauza kuti ndi oyera kwambiri,” adatero.

Chifukwa china chomwe utoto woyera umakhala wonyezimira kwambiri chifukwa particles za barium sulfate ndi zazikulu zosiyana. Tinthu tating'ono ta barium sulphate timamwaza kuwala bwino. Choncho, tinthu ting'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono timathandizira kufalitsa kuwala kwa dzuwa.

Kuchuluka kwa tinthu tating'ono mu utoto ndiyo njira yabwino kwambiri yopangira zoyera kuti ziwonekere. Koma choyipa chake ndichakuti kuchuluka kwa tinthu tating'onoting'ono kumapangitsa kuti penti ikhale yosavuta. Choncho, mwachiwonekere, kukhala utoto woyera sibwino kwenikweni.

Utoto wapezeka kuti umaziziritsa malo opaka utoto. Usiku, utoto umapangitsa kuti pakhale malo ozizira madigiri 19 kuposa china chilichonse chozungulira chinthu chopentidwa. Kukatentha kwambiri, kumazizira pamwamba pa madigiri 8 kuposa zinthu zozungulira.

Timadabwa kuti kutentha kocheperako kungachepetse bwanji ndi kuyesa kowonjezereka. Ngati zoyeserera zokhala ndi utoto woyera zingachepetse kutentha kwambiri, choziziritsa mpweya chikhoza kutha. Kapena kuchepetsa kufunika koyatsa mpweya m'galimoto kapena kunyumba.
