Tsim cov qauv ntawm cov qauv tshuaj siv LEDs! Spice lawv nrog 7-ntu qhia thiab koj tau txais cov duab puab zoo nkauj!

Yeej, koj tso ua ke LEDs thiab 7-ntu qhia nyob rau hauv xws li txoj hauv kev uas ua qauv qauv tshuaj lom neeg. Txhua qhov tivthaiv nruab nrab yog ib qho atom thiab txhua yam zoo li nws zoo ib yam li cov duab geometry tiag tiag. Lawv ua khoom plig zoo heev vim tias lawv tuaj yeem yog tus kheej heev. Koj tuaj yeem xaiv cov qauv uas piav qhia meej txog tus neeg tau txais khoom plig, ua rau nws tshwj xeeb dua.

Kauj Ruam 1: Nrhiav Koj Cov Molecule

Ib qho qauv zoo yuav tsum yog qhov nyuaj thiab tsim cov qauv sib txuam. Cov organic molecules nyuaj tiag tiag ua haujlwm tau zoo tshaj plaws. Vikipedia yog qhov chaw zoo los nrhiav cov lwg me me vim tias lawv muaj cov duab ntawm cov qauv ntawm cov molecule ntxiv nrog cov lus piav qhia luv luv ntawm nws cov khoom. piav qhia tus neeg txais khoom. Piv txwv li, thawj cov qauv kuv tau ua yog acetylcholine uas kuv muab rau kuv tus phooj ywg Coline. Qhov thib ob uas kuv tau ua yog phenethylamine, ib yam khoom hu ua "tshuaj lom neeg". Nov yog qee qhov lwm cov tswv yim pom zoo 1) serotonin - antidepressant2) tryptophan - ua rau koj tsaug zog 3) dopamine - "khoom plig" thiab txaus siab neurotransmitterFor qhov kev qhia no peb yuav tsim kho estradiol variant ntawm estrogen, poj niam hormone

Kauj Ruam 2: Yuav Koj Cov Khoom

Koj daim ntawv teev npe yuav nyob ntawm cov qauv uas koj tau xaiv. Yam koj xav ua yog xaiv ib feem rau txhua lub atom hauv koj lub cev. Rau feem ntau, vim koj feem ntau yuav tau ua cov organic molecule, carbon atoms yuav piav qhia tus qauv. Siv LED los sawv cev cov pa roj carbon atoms. Ntawm tus kheej, kuv nyiam koom nrog cov pa roj carbon ntsuab, yog li kuv siv cov LED ntsuab. Yuav ntau cov LEDs ntsuab raws li muaj cov pa roj carbon atoms hauv koj lub cev rau lwm cov ntsiab lus tam sim no hauv koj cov qauv, koj tuaj yeem siv cov xim sib txawv LED, tab sis kuv pom nws zoo dua los siv 7-ntu zaub nrog cov cim cim sau rau ntawm nws (ntau dua hauv qab no). Cov atoms xws li oxygen thiab nitrogen yog qhov zoo heev sawv cev los ntawm 7-ntu qhia. Ntau nco ntsoov tias hydrogen atoms tsis tau piav qhia meej hauv cov duab puab. Vim li cas? Xyaum ua. Cov tshuaj organic ib txwm muaj tuaj yeem muaj txog 30 hydrogen atoms thiab qhov ntawd ntau dhau lawm. Kuv pom nws zoo tshaj plaws suav nrog hydrogen tsuas yog ntawm cov "pawg tshwj xeeb" zoo li OH (hydroxide) thiab NH2/NH3 (amine). Kuv zoo li koom nrog hydrogen nrog cov xim dawb yog li kuv siv dawb LEDs (uas yog qhov zoo me ntsis). Yog li rau qhov haujlwm estradiol peb yuav xav tau 18 lub teeb ntsuab ntsuab (rau 18 carbon atoms) 2 hom anode (ELS402) xya-ntu qhia (rau 2 lub pa oxygen) 2 LEDs me me dawb (rau 2 hydrogens hauv pawg hydroxide (OH)) Koj tseem yuav xav tau lub roj teeb clip, 1kOhm resistor, soldering hlau thiab hlau. Koj kuj tseem yuav xav yuav lub thawv ntawv yog tias koj yuav muab qhov khoom plig no.

Kauj Ruam 3: Pib Tsim Koj Li Molecule: Carbon Backbone

Nov yog cov txheej txheem kuv tau siv los koom ua ke LEDs los tsim lub nplhaib benzene (qhov hexagonal ib feem). Koj tuaj yeem siv cov txheej txheem ib yam los tsim cov saw ntawm LEDs ntawm txhua yam duab. Ua ob lub LEDs thiab muab tso ua ke raws li qhia hauv daim duab thawj. Koj tuaj yeem muaj cov LEDs ua cov ces kaum, tab sis txij li qhov no yuav yog ib feem ntawm lub nplhaib benzene, lawv tau kaum ntawm 120 degrees. Nyem lawv ob txhais ceg ua ke zoo li qhov no kho lawv nyob rau hauv qhov chaw nws yuav yooj yim rau lawv kom yaj. Qhov kuv txhais tau tias yog kom muab lawv tso rau hauv txoj kev uas lawv zoo ib yam. Rau kev sib tham, kuv tso tus ceg ntev (zoo) nyob rau sab saum toj. Ntau yuav tsum ceev faj tsis txhob cia cov neeg muag muag kov, ua rau lawv luv. Txheeb xyuas yog tias nws ua haujlwm los ntawm kev siv hluav taws xob hla ob txhais ceg. Txhua lub Cheeb Tsam yuav tsum teeb pom kev. Muaj cov txheej txheem kom txog thaum koj tau txais cov qauv uas xav tau, siv txhua lub sijhawm kom pom tias nws tseem pom teeb. Tom ntej no kuv yuav qhia yuav ua li cas tso 7-ntu zaub ntxiv nrog rau qhia cov txheej txheem uas kuv tau siv rau ntawm cov "lo lus".

Kauj Ruam 4: Pib Tsim Koj Li Molecule: 7-ntu Element

Cov kauj ruam no tsis yooj yim vim tias koj yuav tsum nkag siab li cas 7-ntu qhia ua haujlwm li cas. Ntawm qhov ib txwm siv anode 7-ntu zaub, koj muaj 8 tus pin uas sib haum rau 8 "teeb" (7 ntu + 1 tus lej cim zauv) thiab 2 lub koob pins (lawv tau rov ua dua tshiab. Saib daim duab thib ob rau qhov ua piv txwv. Yog li yog tias koj yuav tsum sau tsab ntawv O, Koj tsaws tag nrho tab sis ib tus pin uas sib haum rau ntu ntu nruab nrab. Yog tias koj yuav tsum sau tsab ntawv F koj ua rau tag nrho cov pins tshwj tsis yog hauv qab thiab ob sab sab ntu. Qhov no yog cov txheej txheem uas kuv tau siv los txuas 7-ntu qhia (saib rau thawj daim duab) 1) Khoov tus pin tiaj tus sab hauv. 2) Ntxig ib lub xaim (tej zaum tus tiv thaiv lossis LED ceg) hla tus pin khoov thiab muab tso rau hauv qhov chaw. (daim duab thib plaub) 3) Txiav cov pins uas koj tsis xav tau rau hauv av (ib qho uas sib thooj rau ntu uas koj tsis xav kom teeb) 4) Khoov cov pins ntxiv ua ke mus rau nruab nrab. 5) Muab lwm tus xov tooj lub sij hawm no tso rau ntawm cov pins uas seem. Solder rau hauv qhov chaw. (daim duab thib plaub) Koj yuav xaus nrog qhov pom 7-ntu nrog ob lub xov hlau tawm ntawm nws. Txuas qhov no rau hauv koj lub cev ib yam li koj yuav ua nrog LED. Ceev faj nrog lub polarity!

Kauj Ruam 5: Pib Tsim Koj Cov Molecule: Qhov Loj Peb

Cov txheej txheem tshuaj feem ntau tsis yog dav hlau. Qee cov lwg me me muaj cov atoms uas tawm hauv cov lus qhia sib txawv. Txhawm rau ntxiv LED uas tawm mus, Kuv pom nws zoo tshaj plaws los kho ob txhais ceg ntawm LED raws li pom hauv thawj daim duab. Muab lub LED tso rau hauv qhov chaw hauv koj lub cev thiab koj zoo mus. Koj tuaj yeem siv tib cov txheej txheem los txuas LEDs ntawm ntau lub kaum ntse ntse. Koj tuaj yeem pom cov LED lo tawm ntawm cov molecule ntawm daim duab thib peb.*NCO TSEG: Kuv nyuam qhuav pom tau tias kuv tus qauv tsis zoo li geometrically. Kuv yuav tsum tau tsim tetrahedrons ntawm ob thiab thib peb benzene rings. Cov txheej txheem teev tseg hauv qib no tuaj yeem siv los ua cov duab tetrahedral.

Kauj Ruam 6: Ntxiv qhov Touches Finishing

1) Cov kab laug sab ntawm lub roj teeb clip -Thov ceeb toom ntawm polarity: Cov kab xaim liab rau sab zoo ntawm koj lub cev. Cov xaim dub mus rau sab hauv av. NCO TSEG: Koj yuav tsum tso lub resistor nruab nrab ntawm cov molecule thiab cov xaim liab zoo los tiv thaiv kev hlawv koj cov LEDs. Kuv yeej tsis nco qab ua qhov no, tab sis nws tseem yuav muaj kev nyab xeeb zoo vim tias koj tau txais ntau lub LEDs hauv kev sib koom sib koom tam sim no. 2) (xaiv tau) Muab nws tso rau hauv qhov thaiv. Qhov thaiv uas kuv tau txais muaj lub hau ntswj. Nws yog qhov zoo kov kom tau txais tus neeg siv khoom plig siv lub hau ntswj kom "tsis thim" qhov khoom plig Nco ntsoov tias kuv tsis tau tso roj teeb nrog nws. Kuv kuj tsis tau qhia nws tias nws yog dab tsi tiag. Nws yuav tsum tau txiav txim siab tias nws yuav tsum tau kaw lub roj teeb, thiab nws yuav tsum tau ua qee qhov kev tshawb fawb ib yam (nws tau hais txog qhov Merck Index). Raws li cov txiv ntoo nyob saum, kuv tau nug nws kom thaij duab tag nrho cov taws. Kuv mam li tshaj tawm nws ntawm no tom qab nws ua. EEDIT: pom daim duab kawg nrog nws txhua lub teeb!
