Ferrofluid

Mmiri ndị a na-anọkarị n'ọnọdụ mmiri mmiri ọbụlagodi mgbe a na-achịkwa ha, kwagara, ma ọ bụ jiri mpaghara magnetik na-emekọrịta ihe.

4. Ferrofluids nwere ike agba agba siri ike ma nwee ike imebi akpụkpọ anụ, iko, na ọbụna seramiiki.

N'otu oge ahụ, ike ndọda na-agbalị ịkwatu ogidi ndị ahụ, ebe esemokwu dị n'elu nke mmanụ na-eme ka kọlụm ọ bụla dọpụta onwe ya, na-emepụta ihe e ji mara agịga mmiri.

9. Mmiri magnetik na-aghọwanye ewu ewu dị ka onye na-emepụta nkà. Ụfọdụ ụlọ ngosi ihe nka na sayensị nwere ihe ngosi pụrụ iche nke ewepụtara maka mmiri mmiri ndị a dị ịtụnanya.

13. NASA anwalewokwa mmiri igwe mmiri na-ekpo ọkụ na oghere mechiri emechi na electromagnets dịka usoro njikwa elu.

Ị nwere ike imetụ ferrofluid aka?

1. Ferrofluids, ya bụ ferrofluids, bụ ndị NASA's Steve Papel mepụtara na 1960 iji nyere aka ịkwaga propelant na microgravity.

N'ezie ị nwere ike, mana akwadoghị ya. A na-ewere Ferrofluid dị ka nnukwu mgbakasị anụ ahụ.

Agbanyeghị, na 2019, otu ndị nyocha sitere na Mahadum Massachusetts na Mahadum teknụzụ kemịkalụ Beijing nwere ihe ịga nke ọma n'ịmepụta mmiri magnetik nke nwere ike ịdịgide na-adịgide adịgide. Ọganihu a gbara nkwenye siri ike aka na ọ bụ naanị oke ahụ siri ike nwere ọdịdị edobere nwere ike ime ihe a.

6. A na-enyocha Ferrofluids ugbu a maka ọgwụgwọ etuto ahụ. Echiche bụ ịgbanye ha n'ime etuto ahụ wee dọwaa ha site na iji oghere magnetik.

Nke a na-egbochi irighiri oxide iron si na-ewulite na ikewapụ na mmanụ ebu - dị ka ị ga-ahụ ma ọ bụrụ na ị gwakọtara irighiri mmanụ na irighiri ígwè oxide.

Ferrofluids, dị ka ferrofluids, na-abụkarị nke nanosized ụmụ irighiri ihe, nke ọ bụla n'ime ha na-ejikarị ihe mkpuchi na-ekpuchi ya iji gbochie nchịkọta ha. Ferrofluids n'ozuzu na-efunahụ magnetism ha na-ebute mgbe ewepụrụ ya na oghere magnetik dị n'èzí.

Mmiri ndị a adịghị adị na okike ma bụrụ nke mbụ e kere n'etiti 1960s na 1970s. Nkwadebe mbụ nke ihe ndị a dị ịtụnanya dị oke ọnụ, na-efu ihe dịka $85 kwa ml.

12. Surfactants dị mkpa maka ferrofluids n'ihi na ha na-ebelata esemokwu elu n'etiti mmiri mmiri na ihe siri ike. A na-eji oleic acid, tetramethylammonium hydroxide, citric acid ma ọ bụ soy lecithin mee ihe maka nzube a.

"Colloid usoro esịnede otu-ngalaba magnetik nanoparticles chụsasịrị na a ụgbọelu mmiri mmiri bụ adaba nlereanya usoro nke na-amụ isi Njirimara nke magnetik nanoparticle usoro."

N'ihi nke a, a na-eziga ferrofluid n'ozuzu ya na ogidi ndị etinyere.

N'ụzọ ndị a egweri, oleic acid ka a na-a na-eji mee ka ọ kwụsie ike dispersions na kerosene na ndị ọzọ hydrocarbon mgbasa ozi mgbasa ozi.

Ferrofluids, dị ka sayensị si kwuo bụ:

Ọ bụghị naanị na ọ na-ele anya na-adịghị mma, ma ọ nwere ike ịkpasu gị iwe. Ọ nwekwara ike ịhapụ ntụpọ na-adịgide adịgide na akpụkpọ ahụ.

Ferrofluids, dị ka anyị hụworo, nwere obere irighiri ihe nke iron oxide. Mgbe magnet na-adọta nso mmiri mmiri, ihe ndị a na-adọrọ mmasị na ya.

8. A na-eji ụfọdụ ferrofluids mee ihe na usoro nkwụsị ụgbọ ala. Site n'ịgbanwe ọkụ eletrik site na ha, mmiri ahụ na-edozi isi ike nke nkwusioru dabere na ọnọdụ ịnya ụgbọ ala.

Kedu ka ferrofluids si arụ ọrụ?

11. A-ahụkarị ferrofluid mejupụtara 5% magnetik solids, 10% surfactants na 85% mmiri mmiri.

Ya mere, na-enweghị mmasị ọzọ, ebe a bụ eziokwu 15 banyere ihe ndị dị ebube bụ ferrofluids. Ndepụta a adịchaghị agwụ agwụ na ọ nweghị usoro ọ bụla.

N'ebe a, anyị ga-eleba anya na ihe ha bụ na otú ha si arụ ọrụ.

7. A na-atụ anya na mmiri magnetik nwere ike inye aka ịmepụta mmiri mmiri dị mma n'ọdịnihu. Mmiri ndị dị otú ahụ nwere ike ịgbanwe ọnọdụ n'etiti siri ike na mmiri mmiri na iwu.

2. Mgbe mmiri ndị a na-ekpughere oghere magnetik, ha na-etolite spikes ma ọ bụ agịga njirimara.

10. O nwekwara ike ịbụ na ị hụla ferrofluids na vidiyo egwu karịa ole na ole. Dịka ọmụmaatụ, Pendulum band ji ferrofluid maka vidiyo egwu maka egwu "Watercolor".

14. Ferrofluids dị ka ferrofluids na-eji taa na teknụzụ dị iche iche. A na-eji igwe na-ekwu okwu, draịva siri ike kọmpụta, moto shaft na-atụgharị, yana dịka onye nnọchi anya MRI.

5. Ezi ferrofluid na-anọgide na-adịgide adịgide ruo ogologo oge. Nke a bụ n'ihi na ụmụ irighiri ihe ndị siri ike ha nwere adịghị eme ka ọ dị elu ma ghara ikewa n'okpuru mmetụta nke ike ndọda.

3. Ọtụtụ mmiri mmiri magnetik anaghị anọgide na-eme ka magnetik na-enweghị ebe ndọta dị n'èzí.

Kedu ihe bụ mmiri magnetik?

N'ihi nke a, a na-ekewa ha dị ka "superparamagnets".

Ụzọ ọdịnala maka nkwadebe nke mmiri magnetik gụnyere iji bọọlụ igwe gweri ihe ndọta ogologo oge ruo ọtụtụ izu n'ime ihe na-ebu ibu nwere ihe na-agbasa.

Nke a na-ebutekarị mmiri mmiri na-emepụta agịga ma ọ bụ spikes dị ịtụnanya. Ihe kpatara nke a na-adabere na mmekọrịta dị mgbagwoju anya nke ndị agha dị iche iche.

Nke mbụ NASA mepụtara maka mmemme oghere, mmiri ndọta achọpụtala ụzọ ha n'ọtụtụ akụkụ nke ụwa ọgbara ọhụrụ. Site na iji vidiyo egwu gaa na igwe okwu na nyocha MRI, mmiri ndọta dị gburugburu anyị taa.

15. Ferrofluids ekwesịghị inwe mgbagwoju anya na mmiri magnetorheological. Nke ikpeazụ nwere ihe dị ka micrometer nke ga-emecha dozie n'okpuru mmetụta nke ike ndọda.

Akụkụ na mmanụ na-arụkọ ọrụ ọnụ dị ka otu n'ihi ọnụnọ nke surfactant. Otu njedebe nke surfactant na-arapara n'ahụ ahụ nke ọma na ígwè oxide, ebe nke ọzọ na-ejidekwa mmanụ ahụ.

Ozugbo i ji mkpịsị aka gị metụ ferrofluid ahụ aka, mmiri mmiri na-amalite ngwa ngwa na-ebuli mkpịsị aka na gburugburu ntu ahụ.

A na-adọta ụmụ irighiri ígwè oxide na oghere magnetik, na oghere magnetik n'onwe ya na-adọrọkwa mmasị na mmiri mmiri.

Otu ihe atụ a na-akpọ ferrofluid ma ọ bụ ferrofluid. Ferrofluid a na-aghọ nnukwu magnetized n'ihu ebe ndọta ma NASA mepụtara ya na mbido 1960s.

Emebere ya ka ọ chọta ụzọ a ga-esi ebugharị ihe na-eme mmiri mmiri na ntinye nke mgbapụta na ike ndọda dị ala ma ọ bụ enweghị ịdị arọ.

Ọnụ ego a dị elu na mbụ gbochiri iji ihe a na-eme ihe na sayensị ihe na mineralogy. Mana nnyocha ụlọ ọrụ na-ahụ maka ogbunigwe na United States mechara jiri magnetite na mmanụ ọkụ belatara ọnụ ahịa ya ihe dị ka $1 kwa lita.
