Mawindo amathandizira 60% ya mphamvu zomwe zimatayika m'nyumba.M'nyengo yotentha, mazenera amatenthedwa kuchokera kunja, akutulutsa mphamvu yotentha m'nyumbayo.Kunja kukazizira, mazenera amatenthetsa kuchokera mkati, ndipo amatulutsa kutentha kumadera akunja.Njirayi imatchedwa kuzirala kwa ma radiation.Izi zikutanthauza kuti mazenera sagwira ntchito kuti nyumbayo ikhale yotentha kapena yozizira monga momwe iyenera kukhalira.

Kodi zingatheke kupanga galasi lotha kuyatsa kapena kuzimitsa palokha kuziziritsa kumeneku malinga ndi kutentha kwake?Yankho ndi lakuti inde.

Lamulo la Wiedemann-Franz limanena kuti kuwongolera kwamagetsi kwazinthuzo kumapangitsa kuti matenthedwe azitha bwino.Komabe, zinthu za vanadium dioxide ndizosiyana, zomwe sizitsatira lamuloli.

Ofufuzawo adawonjezera gawo lochepa la vanadium dioxide, chigawo chomwe chimasintha kuchokera ku insulator kupita ku conductor pafupifupi 68 ° C, kupita mbali imodzi ya galasi.Vanadium dioxide (VO2)ndi zinthu zinchito ndi mmene thermally kuchititsa gawo kusintha.Mapangidwe ake amatha kusinthidwa pakati pa insulator ndi chitsulo.Imakhala ngati insulator kutentha kwa chipinda komanso ngati kondakitala wachitsulo pa kutentha pamwamba pa 68 ° C.Izi ndichifukwa choti mawonekedwe ake a atomiki angasinthidwe kuchokera ku chipinda cha kristalo cha kutentha kwa chipinda kupita ku zitsulo zachitsulo pa kutentha pamwamba pa 68 ° C, ndipo kusinthaku kumachitika mu zosakwana 1 nanosecond, zomwe ndi zabwino kwa magetsi.Kafukufuku wofananira wapangitsa anthu ambiri kukhulupirira kuti vanadium dioxide ikhoza kukhala chinthu chosinthira makampani azamagetsi amtsogolo.

Ofufuza pa yunivesite ya ku Switzerland anawonjezera kutentha kwa vanadium dioxide kufika pamwamba pa 100 ° C powonjezera germanium, chinthu chosowa kwambiri chachitsulo, ku filimu ya vanadium dioxide.Achita bwino pakugwiritsa ntchito kwa RF, pogwiritsa ntchito vanadium dioxide ndi ukadaulo wosinthira magawo kuti apange zosefera zamtundu wa Ultra-compact, zosinthika kwanthawi yoyamba.Mtundu watsopano wa fyuluta ndi woyenera makamaka kwa mafupipafupi omwe amagwiritsidwa ntchito ndi machitidwe olankhulana mlengalenga.

Kuphatikiza apo, zinthu zakuthupi za vanadium dioxide, monga resistivity ndi infrared transmittance, zidzasintha kwambiri panthawi ya kusintha.Komabe, ntchito zambiri za VO2 zimafuna kuti kutentha kuzikhala pafupi ndi kutentha kwa chipinda, monga: mawindo anzeru, zowunikira zowunikira, ndi zina zambiri, ndi doping zimatha kuchepetsa kutentha kwa gawo.Doping tungsten element mufilimu ya VO2 imatha kuchepetsa kutentha kwa gawo la filimuyo mpaka kutentha kwa chipinda, kotero VO2 ya tungsten-doped VO2 ili ndi chiyembekezo chogwiritsa ntchito.

Akatswiri a Hongwu Nano adapeza kuti kutentha kwa vanadium dioxide kumatha kusinthidwa ndi doping, kupsinjika, kukula kwambewu, ndi zina zambiri. Zinthu za doping zimatha kukhala tungsten, tantalum, niobium ndi germanium.Tungsten doping imawonedwa ngati njira yothandiza kwambiri ya doping ndipo imagwiritsidwa ntchito kwambiri kusintha kutentha kwa gawo.Doping 1% tungsten ikhoza kuchepetsa kutentha kwa gawo la vanadium dioxide ndi 24 °C.

Mafotokozedwe a pure-phase nano-vanadium dioxide ndi tungsten-doped vanadium dioxide omwe kampani yathu ingapereke kuchokera ku katundu ndi awa:

1. Nano vanadium dioxide ufa, wosasinthika, gawo loyera, kutentha kwa gawo ndi 68 ℃

2. Vanadium dioxide doped ndi 1% tungsten (W1% -VO2), kutentha kwa gawo ndi 43 ℃

3. Vanadium dioxide doped ndi 1.5% tungsten (W1.5% -VO2), kutentha kwa gawo ndi 32 ℃

4. Vanadium dioxide doped ndi 2% tungsten (W2% -VO2), kutentha kwa gawo ndi 25 ℃

5. Vanadium dioxide doped ndi 2% tungsten (W2% -VO2), gawo kusintha kutentha ndi 20 ℃

Poyembekezera zam'tsogolo, mazenera anzeru awa okhala ndi tungsten-doped vanadium dioxide akhoza kuikidwa padziko lonse lapansi ndikugwira ntchito chaka chonse.
