Lub hnub ci hluav taws xob hluav taws xob yog ib kauj ruam ze dua los ua ib feem ntawm peb lub neej ua tsaug rau "radical" tshiab kev tshawb fawb.
Xyoo 2017, cov kws tshawb fawb ntawm ib lub tsev kawm ntawv Swedish tau tsim lub zog uas ua rau nws tuaj yeem ntes thiab khaws lub hnub ci zog ntev txog 18 xyoo, tso tawm raws li cua sov thaum xav tau.
Tam sim no cov kws tshawb fawb tau ua tiav hauv qhov system los tsim hluav taws xob los ntawm kev txuas nws mus rau lub tshuab hluav taws xob thermoelectric.Txawm hais tias tseem nyob rau theem pib, lub tswv yim tsim los ntawm Chalmers University of Technology hauv Gothenberg tuaj yeem ua txoj hauv kev rau nws tus kheej-them hluav taws xob uas siv lub hnub ci zog ntawm kev thov.
"Qhov no yog txoj hauv kev tshiab tshaj plaws ntawm kev tsim hluav taws xob los ntawm lub hnub ci zog.Nws txhais tau hais tias peb tuaj yeem siv lub hnub ci los tsim hluav taws xob tsis hais huab cua, lub sijhawm nruab hnub, lub caij, lossis thaj chaw nyob," piav qhia tus thawj coj tshawb fawb Kasper Moth-Poulsen, xibfwb ntawm Department of Chemistry thiab Chemical Engineering ntawm Chalmers.
"Kuv zoo siab heev rau txoj haujlwm no," nws hais ntxiv."Peb cia siab nrog kev txhim kho yav tom ntej no yuav yog ib feem tseem ceeb hauv lub zog yav tom ntej."
Lub hnub ci zog yuav khaws cia li cas?
Hnub ci zog yog qhov hloov pauv hloov tau dua tshiab vim tias feem ntau nws, nws tsuas yog ua haujlwm thaum lub hnub ci.Tab sis thev naus laus zis los tawm tsam qhov kev sib tham ntau qhov tsis zoo no twb tau tsim los ntawm kev nrawm nrawm.
Hnub ci vaj huam sib luag tau tsim los ntawm cov qoob loo pov tseg uasnqus UV teeb txawm nyob rau hnub huab cuathaum 'hmo ntuj solar panels' tau raug tsim ua haujlwm txawm tias lub hnub tau teeb tsa.
Lub sij hawm ntev cia ntawm lub zog lawv tsim yog lwm qhov teeb meem.Lub hnub ci zog tsim ntawm Chalmers rov qab rau xyoo 2017 yog lub npe hu ua 'MOST': Molecular Solar Thermal Energy Storage Systems.
Lub tshuab yog ua raws li cov qauv tsim tshwj xeeb ntawm carbon, hydrogen thiab nitrogen uas hloov cov duab thaum nws los rau hauv kev sib cuag nrog lub hnub ci.
Nws zoo li-hloov mus rau hauv ib qho 'zog-nplua nuj isomer' - ib lub molecule ua los ntawm tib lub atoms tab sis teem ua ke nyob rau hauv ib txoj kev sib txawv.Cov isomer tuaj yeem muab khaws cia rau hauv daim ntawv ua kua rau tom qab siv thaum xav tau, xws li thaum hmo ntuj lossis hauv qhov tob ntawm lub caij ntuj no.
Lub catalyst tso tawm lub zog txuag raws li cua sov thaum rov qab cov molecule rau nws cov qauv qub, npaj siv dua.
Tau ntau xyoo, cov kws tshawb fawb tau ua kom zoo dua qhov system mus rau qhov chaw uas tam sim no muaj peev xwm khaws cia lub zog rau 18 xyoo zoo kawg.
Ib qho 'ultra-thin' nti hloov lub hnub ci zog rau hauv hluav taws xob
Raws li tau piav qhia hauv ib txoj kev tshawb fawb tshiab tau luam tawm hauvCell Reports Physical ScienceLub hli tas los, cov qauv no tam sim no tau ua ib kauj ruam ntxiv.
Cov kws tshawb fawb Swedish tau xa lawv cov molecule tshwj xeeb, ntim nrog lub hnub ci zog, rau cov npoj yaig ntawm Shanghai Jiao Tong University.Nyob ntawd lub zog tau tso tawm thiab hloov mus rau hauv hluav taws xob siv lub tshuab hluav taws xob uas lawv tau tsim.
Qhov tseem ceeb, Swedish tshav ntuj raug xa mus rau lwm sab ntawm lub ntiaj teb thiab hloov mus rau hauv hluav taws xob hauv Suav teb.
Qhov tseem ceeb, Swedish tshav ntuj raug xa mus rau lwm sab ntawm lub ntiaj teb thiab hloov mus rau hauv hluav taws xob hauv Suav teb.
"Lub tshuab hluav taws xob yog cov nti ultra-nyias uas tuaj yeem ua ke rau hauv cov khoom siv hluav taws xob xws li lub mloog pob ntseg, smartwatches thiab xov tooj," hais tias tus kws tshawb fawb Zhihang Wang los ntawm Chalmers University of Technology.
"Txog tam sim no, peb tsuas yog tsim hluav taws xob me me xwb, tab sis cov txiaj ntsig tshiab qhia tau tias lub tswv yim ua haujlwm tiag tiag.Nws zoo li muaj kev cia siab heev. "
Cov cuab yeej tuaj yeem hloov tau cov roj teeb thiab lub hnub ci, ua kom zoo rau txoj kev uas peb siv lub hnub ci ntau zog.
Cia hnub ci: Ib txoj hauv kev tsis muaj pob txha thiab emissions ntawm kev tsim hluav taws xob
Qhov kev zoo nkauj ntawm qhov kaw, lub voj voog yog tias nws ua haujlwm tsis ua rau CO2 emissions, txhais tau tias nws muaj peev xwm siv tau nrog lub zog tauj dua tshiab.
Qhov tseeb UN Intergovernmental Panel ntawm Climate Change(IPCC) qhiaua rau nws pom tseeb heev tias peb yuav tsum tau ua kom rov ua dua tshiab thiab hloov mus deb ntawm fossil fuels ntau, sai dua kom muaj kev nyab xeeb rau yav tom ntej huab cua.
Thaum tseem ceeb nce qib hauvhnub ci zogzoo li qhov no ua rau muaj kev cia siab, cov kws tshawb fawb ceeb toom tias nws yuav siv sijhawm rau cov thev naus laus zis los ua ke rau hauv peb lub neej.Ntau qhov kev tshawb fawb thiab kev txhim kho tseem nyob ua ntej peb yuav tuaj yeem them peb cov khoom siv hluav taws xob lossis cua sov peb lub tsev nrog lub kaw lus khaws cia hnub ci zog, lawv tau sau tseg.
Moth-Poulsen hais tias "Ua ke nrog ntau pab pawg tshawb fawb suav nrog hauv qhov project, tam sim no peb tab tom ua haujlwm los txhim kho cov txheej txheem," Moth-Poulsen hais."Tus nqi hluav taws xob lossis cua sov nws tuaj yeem rho tawm yuav tsum tau nce ntxiv."
Nws hais ntxiv tias txawm tias cov txheej txheem ua raws li cov ntaub ntawv yooj yim, nws yuav tsum tau hloov kho kom nws thiaj li raug nqi tsim khoom ua ntej nws tuaj yeem tsim tawm ntau dua.
