He aha ka Nanometer?

Hint: Nā hoʻohana liʻiliʻi nā mino liʻiliʻi

He nanometer (nm) kekahi pae o ka lōʻihi ma ke anapuni metric, i like ka hoʻokahi miliona o ka meter (1 x 10-9 m). He nui ka poʻe i lohe i ka mea ma mua-ke pili pinepine nei me ka nanotechnology a me ka hanaʻana a me ke aʻoʻana i nā mea liʻiliʻi loa. ʻO kēia nanometerʻoi aku ka liʻiliʻi ma mua o ka meter, akā e hiki paha iāʻoe ke noʻonoʻo pehea ka liʻiliʻi? A iʻole, he aha nāʻano o nāʻoihana a nā huahana maoli i hana ma kēia paona nanoscopic?

A iʻole, pehea e pili ai i nā ana o nā lōʻihi o ka lōʻihi?

Pehea ka liʻiliʻi he Nanometer?

ʻO nā ana o ke kaulike ke kauʻia ma luna o ka meter. E nānā i kekahi mō'ī a me ke anaʻana, aʻikeʻoe i nā helu heluʻia no nā mika, centimeters, a me ka millimeters. Me ka penikala mechanical a me ka lima paʻa,ʻaʻole hikiʻole ke huki i nā laina hoʻokahi millimita kaʻawale. I kēia manawa e noʻonoʻoʻoe i kahi miliona miliona mau laina likeʻole i loko o ka mīkini mile -ʻo ia kahi nanometer. ʻO ka hanaʻana i kēlā mau laina e koiʻia ana nā meaʻoihana kūikawā mai:

• 'O ke nanometer (nm) ka liʻiliʻi ma mua o ka ..

• micrometer (μm), ka mea liʻiliʻi ma mua o ka ..

• millimeter (mm), ka mea liʻiliʻi ma mua o ka ..

• he centimeteri (cm), a ua emi iho ka liʻiliʻi ma mua o ka ..

• decimeter (dm), ka mea liʻiliʻi ma mua o ka ..

• mita (m)

Me ke kōkuaʻoleʻia o nā mea hana (e like me nā aniani kilokilo, microscopes), he maka maka o ke kanaka (hiki i kaʻike maka) hiki keʻike i nā mea a pau i kahi oʻelua haneri haneli ka nui o ke anawaena,ʻo ia he 20 micrometers.

No ka hāʻawiʻana i ka nui o 20 micrometers kekahi mau'enepili, e nānā inā hiki iāʻoe ke hōʻoia i hoʻokahi kānana / acrylic fiʻili e huki mai ana mai kahiʻaʻahi (e hoʻopaʻa iā ia e kū'ē i kahi mālamalamaʻike e kōkua nui) aiʻole e lele ana i ka lewa e like me ka lepo. A iʻole e'ānai i kahi lepo maikaʻi ma ka poho o kou lima eʻike i nā liʻiliʻi liʻiliʻi loa,ʻikeʻole.

Inā he mau mea paʻakikī ke hana, e nānā i nā lauoho kanaka, ma kahi o 18 micrometers (maikaʻi loa) i 180 micrometers (koʻikoʻi) ke anawaena.

Aʻo nā mea a pau i kūpono i ka pae micrometer - nā mea nanometer-sized-mea i loaʻa he mau manawa hou!

Nā Atomi a me nā Pūnaewele

Nānā i keʻano nanoscale i nā ala i waena o hoʻokahi a me 100 nanometers, e komo pū ana nā mea a pau mai ka'eneki a i nā kele pūnaewele. Loaʻa nā huapalapala mai 50 a 200 mau nanometers i ka nui. ʻO ka mīkini lahilahi o kahi membrane paʻakikī ma waena o 6 nanometers a me 10 nanometers. ʻO ka helix o ka DNAʻo ia e pili ana i 2 nanometers i ke anawaena, aʻo nā nanotubesona carbon can get as small as 1 nanometer in diameter.

Ma ka hāʻawiʻana i kēlā mau hiʻohiʻona, he maʻalahi ka hoʻomaopopo he pono ka mea i hanaʻia me ka mea pono a me nā mea pono (e like me ke kānana ke nānāʻana i nā microscopes) e launa pū me (e like me ke kiʻi, ka ana, keʻano, ka hana, a me ka hana) nā mea ma ke ana nanoscopic. A aia kekahi poʻe e hana nei i kēia mau lā ma nā pālaina e like me:

• Kekema

• ʻO Biology

• Hoʻopaʻa

• Nń Pono Haʻawina

• Ke hoʻohana pūnaewele

• Pānaehana

Nui nāʻano hoʻohālikelike o nā huahana hou i hanaʻia ma keʻano nanometer. ʻO kekahi mau lāʻau lapaʻau i hanaʻia e hiki ai ke hāʻawi i nā lāʻau lapaʻau i nā pūnaewele pono'ī. Hanaʻia nā kinikona'eneka kūikawā e ka papa hana e hana ana i nā moleka me ka pololei pololei o nanometer.

Hoʻohanaʻia nā nanotubes o ka carbon e hoʻonui i nā mea wela a me nā māmā o nā huahana. A me ke aneeo o Samsung Galaxy S8 a me Apple iPad Pro pakuhi (elua-gen) i na mea hana elua i hanaia i 10 nm.

ʻO ka wā e hiki mai ana i ka wā e hiki mai ana nā noiʻi'enekema a me ka technology i nanometer. Eia naʻe,ʻaʻole keʻano o ka nanometer ka mea liʻiliʻi loa! E nānā i ka papa ma lalo nei eʻike i keʻano o kona hoʻohālikeʻana.

ʻO ka Papa Kuhi
