Mene ne Nanometer?

Shawarwari: Ƙananan ƙananan na'urori suna amfani da shi

A nanometer (nm) na ɗaya ne na tsawon cikin tsarin ma'auni, daidai da biliyan ɗaya na mita (1 x 10-9 m). Yawancin mutane sun ji labarin da shi-an haɗa shi da nanotechnology da halitta ko nazarin abubuwa masu kankanin. Babu shakka nanometer ya fi ƙasa da mita, amma zaka iya yin mamaki kamar yadda ƙananan? Ko kuma, wace irin ayyukan da ake amfani da su a cikin wannan samfurin nanoscopic?

Ko kuwa, yaya yake danganta da sauran ma'auni na tsawon?

Yaya Small ne Nanometer?

Matakan ma'aunin ƙananan duka sun dogara da mita. Binciki kowane mai mulki ko ƙaddamar da tef, kuma zaka iya ganin alamomin da aka sanya don mita, centimeters, da millimeters. Tare da fensir na inji da kwalliya, ba wuya a zana layin daya millimeter ba. Yanzu kuyi tunanin ƙoƙari kuyi daidai da layin jita-jita guda daya a cikin wani mintimita - wannan nanometer ne. Yin amfani da waɗannan layi yana buƙatar kayan aiki na musamman tun:

• A nanometer (nm) ya ragu da wani ..

• micrometer (μm), wanda yake karami fiye da ..

• millimeter (mm), wanda yake karami fiye da ..

• centimeter (cm), wanda ya fi ƙanƙan da ..

• decimeter (dm), wanda ya fi ƙanƙanta fiye da ..

• mita (m)

Ba tare da taimakon duk wani kayan aiki ba (eg gilashin girman ƙarfe, microscopes), ido na al'ada (watau hangen nesa) yana iya ganin mutum abubuwa a kimanin nau'i biyu na millimita ɗaya na diamita, wanda yake daidai da 20 micrometers.

Don ba da girman mita 20 na wasu mahallin, duba idan zaka iya gane takalma / acrylic fiber wanda ke fita daga abin sha (adana shi a kan wata maɓallin haske yana taimakawa sosai) ko iyo cikin iska kamar ƙura. Ko kuma satar da yashi mai kyau a cikin dabino na hannunka don gano kananan karami, ƙananan ganewa.

Idan waɗannan suna da wuya a yi, duba kyan jikin mutum a maimakon haka, wanda ke kusa da mikimita 18 (lafiya sosai) zuwa 180 micrometers (sosai m) a diamita.

Kuma duk abin da yake daidai matakin matakin micrometer - abubuwa masu yawa na nanometer sun kasance sau dubu sau ɗaya!

Atoms da Cells

Tsarin nanoscale ya ƙunshi girma tsakanin nau'in daya da 100, wanda ya hada da dukkanin abubuwa daga atomis zuwa matakan cellular. Kwayoyin cuta suna fitowa daga 50 da 200 nau'in nau'i a cikin girman. A matsakaicin kauri daga jikin kwayar halitta yana tsakanin 6 nanometers da 10 nanometers. Helix na DNA yana kimanin 2 nanometers a diamita, kuma nanotubes na carbon zasu iya samun ƙananan kamar 1 nanometer a diamita.

Idan aka ba waɗannan misalai, yana da sauƙi fahimtar cewa yana buƙatar kayan aiki mai ƙwanƙwasa da kuma ƙayyadadden kayan aiki (misali nazarin maɓallin ƙararraki) don yin hulɗa tare da (watau image, ma'auni, samfurin, sarrafawa, da kuma yi) abubuwa akan sikelin nanoscopic. Kuma akwai mutanen da suke yin wannan yau da kullum a cikin fannoni irin su:

• Chemistry

• Biology

• Turanci

• Kimiyyar kayan abu

• Engineering

• Fasaha

Akwai misalan samfurori na samfurori na zamani wanda aka yi a kan sikelin nanometer. Wasu magunguna da ƙananan an tsara don su iya samar da kwayoyi zuwa wasu kwayoyin. Kwayoyin sunadarai na zamani suna haɓaka ta hanyar tsari wanda ke haifar da kwayoyin halitta tare da daidaitattun nanometer.

Ana amfani da nanotubes na carbon Carbon don inganta haɓaka kayan lantarki da lantarki. Kuma samfurin Samsung Galaxy S8 da Apple iPad Pro kwamfutar hannu (na biyu-gen) dukansu sun hada da masu sarrafawa da aka tsara a 10 nm.

Makomar da ke gaba ya fi kariya don aikace-aikace na kimiyya da fasahar nanometer. Duk da haka, nanometer ba ma mahimmin ƙara a kusa ba! Duba tebur da ke ƙasa don duba yadda yake kwatanta.
