Vim nws cov qauv tsis tawg thiab kev ruaj ntseg ntawm cov pa roj carbon atoms, graphene yog heev muaj zog. Graphene cov cov khaubncaws sab nraud povtseg ntawm electrons sib tshooj, lub ntsiab lus tsawg dua teeb lub zog xav tau kom tau txais cov electrons dhia ntawm cov txheej txheem. Nyob rau hauv lub neej yav tom ntej, cov cuab yeej ntawd tuaj yeem ua rau heev siv tau lub hnub ci hlwb.
Ntawm no, puas yog graphene lub teeb?
Graphene tau pom thawj zaug hauv xyoo 2004, tab sis qhov ua rau muaj kev zoo siab yog tias nws cov khoom (txoj kev uas nws coj mus rau cov khoom siv) yog qhov zoo tshaj plaws thiab zoo siab. Luv luv, nws yog super-muaj zog thiab tawv, amazingly nyias, yuav luag tag nrho pob tshab, tsis tshua muaj neeg teeb , thiab ib qho amazing conductor ntawm hluav taws xob thiab cua sov.
Dab tsi ua rau graphene tshwj xeeb? Graphene tau tshwm sim los ua ib qho ntawm cov khoom zoo tshaj plaws nanomaterials vim nws tshwj xeeb ua ke ntawm superbproperties: nws yog tsis tsuas yog ib qho ntawm cov khoom siv thinnest tab sis kuj muaj zog tshaj plaws; nws ua cua sov zoo dua txhua yam khoom siv; nws yog a zoo heev conductor ntawm hluav taws xob; nws yog optically pob tshab, tseem yog li ntawd ntom
Tsuas yog li ntawd, vim li cas graphene nqus lub teeb?
Qhov pom kev sib raug zoo ntawm lub zog photon thiab tom qab ntawd tus naj npawb ntawm cov hluav taws xob ua kom zoo siab qhia tau tias graphene hloov teeb rau hauv hluav taws xob nrog high efficiency. Nws twb paub tias graphene yog muaj peev xwm nqus ib tug heev loj spectrum ntawm teeb xim.
Koj puas tuaj yeem pom los ntawm graphene?
Nws yog qhov zoo tshaj plaws pob tshab, absorbing tsuas yog 2.3 feem pua ntawm lub teeb uas tsaws rau ntawm nws, tab sis yog koj muaj ib daim ntawv dawb los muab piv rau, koj tuaj yeem pom tias nws nyob ntawd. Qhov ntawd txhais tau tias koj tuaj yeem pom ib txheej ntawm atom nrog koj qhov muag liab qab, yog lawv yog graphene . Tab sis ITO yog nkig heev, whereas graphene yog heev
Pom zoo:
Vim li cas graphene siv hauv xov tooj?
Graphene tuaj yeem ua cov roj teeb uas muaj lub teeb, ruaj khov thiab tsim nyog rau lub zog muaj peev xwm khaws cia, nrog rau cov sijhawm them sijhawm luv. Nws yuav txuas ntxiv lub roj teeb lub neej-lub sij hawm, thiab ntxiv conductivity yam tsis xav tau cov pa roj carbon ntau uas yog siv nyob rau hauv cov pa roj teeb
Vim li cas thiaj tseem ceeb kom muaj lub teeb?
Lub teeb yog cov nroj tsuag 'tsuas yog qhov chaw ntawm lub zog, yog li lawv nyob ntawm lub teeb nkaus xwb. Tsis zoo li tib neeg thiab tsiaj txhu uas tau txais lub zog los ntawm carbohydrates, protein thiab rog, cov nroj tsuag tsim cov tshuaj no siv lub zog los ntawm lightand los ntawm carbon dioxide hauv huab cua
Yuav ua li cas koj thiaj paub yog tias tus nqi sib npaug tsis muaj kev daws teeb meem?
Tus nqi tiag tiag ntawm tus lej yog nws qhov kev ncua deb ntawm xoom. Tus lej ntawd yuav yog qhov zoo, vim koj tsis tuaj yeem ua tsis zoo ob txhais taw deb ntawm ib yam dab tsi. Yog li txhua tus nqi sib npaug sib npaug sib npaug rau tus lej tsis zoo yog tsis muaj kev daws teeb meem, txawm tias tus lej ntawd yog dab tsi
Yuav ua li cas yog vim li cas vim li cas lub epigenome hloov?
Kev ua neej nyob thiab ib puag ncig (xws li kev haus luam yeeb, noj zaub mov thiab kab mob sib kis) tuaj yeem ua rau tus neeg muaj kev ntxhov siab uas ua rau muaj tshuaj lom neeg. Cov lus teb no, dhau los, feem ntau ua rau muaj kev hloov pauv hauv epigenome, qee qhov tuaj yeem ua rau puas tsuaj
Yuav ua li cas muaj pes tsawg tus noob sib xyaw ua tau hauv gamete ntau lawm rau Dihybrid cross Vim li cas thiaj muaj ntau?
Muaj peev xwm gametes rau txhua tus niam txiv AaBb Txij li thaum txhua tus niam txiv muaj plaub qhov sib txawv ntawm cov alleles hauv gametes, muaj kaum rau kev sib txuas ua ke rau tus ntoo khaub lig no
