Ukuqonda kanye nezinzuzo ze-Nanotechnology

I-nanotechnology igatsha lesayensi elithuthuka ngokushesha elithembisa ukuguqula imikhakha efana nemithi, ubuchwepheshe bolwazi, amandla, kanye nemvelo. Igama elithi "nanotechnology" libhekisela ekuphathweni kwezinto esikalini se-nanometer, ingxenye eyodwa kweziyizigidigidi zemitha, okuvumela ososayensi ukuthi bakhe futhi balawule izakhiwo ngokunemba okumangalisayo. Lesi sihloko sizochaza incazelo ye-nanotechnology, izimiso zayo eziyisisekelo, kanye nezinzuzo ezahlukahlukene ezinikezayo.

Ukuqonda i-Nanotechnology

I-nanotechnology ichazwa njengokutadisha nokusetshenziswa kwezinto ezincane kakhulu, esikalini se-nanometer. Ukuze sikubeke kahle lokhu, i-nanometer cishe iyinxenye eyodwa kweziyizigidigidi zemitha, noma cishe incane ngokuphindwe kayikhulu kunezinwele zomuntu. Kulesi sikali, izakhiwo zomzimba, zamakhemikhali, kanye nezebhayoloji zezinto zingahluka kakhulu ezimpahleni zazo ezikalini ezinkulu.

Umlando Omfushane We-Nanotechnology

Umqondo we-nanotechnology wethulwa okokuqala yisazi sesayensi yefiziksi esidumile uRichard Feynman enkulumweni yakhe yango-1959, ethi “Kukhona Indawo Eningi Ezansi.” UFeynman wayenombono wekhono lokulawula ngqo ama-athomu nama-molecule. Igama elithi “nanotechnology” ngokwalo lasetshenziswa okokuqala nguNorio Taniguchi ngo-1974, kodwa kwaze kwaba ngawo-1980 no-1990 lapho ubuchwepheshe baqala khona ukuthuthuka ngokushesha ngenxa yokusungulwa kwamathuluzi amasha njenge-scanning tunneling microscope (STM) kanye ne-atomic force microscope (AFM).

Izimiso Eziyisisekelo Zobuchwepheshe Be-Nano

I-nanotechnology ihilela ukuphathwa nokulawulwa kwezinto esikalini se-athomu kanye ne-molecular. Kulesi sikali, izimiso ze-quantum mechanics kanye ne-quantum chemistry zivame ukuba nethonya elikhulu kunemithetho ye-physics yakudala. Ama-nanoparticle angaba nezakhiwo ezihlukile ezihlukile kulezo zezinhlayiya ezinkulu ezifanayo. Isibonelo, ama-nanoparticle egolide angabonakala ebomvu noma eluhlaza okwesibhakabhaka, kuye ngobukhulu bawo kanye nesimo sawo, futhi angaba nezakhiwo ezihlukile ze-catalytic kunegolide eliningi.

I-nanotechnology ivumele intuthuko ebalulekile emkhakheni wezobuchwepheshe bolwazi, okuhlanganisa:

Ama-semiconductor nama-TransistorsUkusetshenziswa kwe-nanotechnology ekukhiqizweni kwe-semiconductor kuye kwavumela ukudalwa kwama-transistors amancane, asheshayo, futhi asebenza kahle. Lokhu kuye kwaba negalelo ekuthuthukisweni kwamakhompyutha namadivayisi kagesi ayinkimbinkimbi kakhulu.
Inkumbulo Yedatha: I-Nanotechnology ivumela ukudalwa kwamadivayisi amancane okugcina idatha anamakhono amakhulu, njengememori ye-flash esheshayo nesebenza kahle kakhulu nama-hard disk.

3. Amandla

Emkhakheni wamandla, ubuchwepheshe be-nano bunikeza izixazululo ezintsha zokuthuthukisa ukusebenza kahle kanye nokusimama:

Amaseli Elanga: I-nanotechnology ingandisa ukusebenza kahle kwamaseli elanga ngokusebenzisa ama-nanoparticles ukuze kuthuthukiswe ukumuncwa kokukhanya nokunciphisa ukulahleka kwamandla.
I-BateraiUkusetshenziswa kwezinto ezisetshenziswa kumabhethri kungandisa amandla, isikhathi sokuphila, kanye nesivinini sokushaja samabhethri, okubaluleke kakhulu ekuthuthukisweni kwezimoto zikagesi kanye nokugcinwa kwamandla avuselelekayo.
I-CatalystAma-nanocatalyst angandisa ukusebenza kahle kwezindlela zamakhemikhali ezinqubweni zokukhiqiza amandla, njengakumaseli kaphethiloli noma izinqubo zokuhlanza uphethiloli.
