Ukusetshenziswa kwe-Nanotechnology ku-Metallurgy
I-nanotechnology iyinsimu eshintsha ngokushesha ethembisa iminikelo ebalulekile emikhakheni eyahlukene, okuhlanganisa ne-metallurgy. I-Metallurgy, ehlanganisa ukutadisha izakhiwo zomzimba nezamakhemikhali zezinsimbi nama-alloy, kanye nobuchwepheshe bokucubungula insimbi, idlule ekuguqukeni okukhulu ngokwethulwa kwe-nanotechnology. I-nanotechnology ivumela ukuphathwa kwezinto esikalini se-athomu nesamangqamuzana, ngokuvamile cishe ama-nanometer ayikhulu kuya kwayikhulu. Kulesi sihloko, sizohlola ukusetshenziswa okuhlukahlukene kwe-nanotechnology ku-metallurgy, kusukela ekuthuthukisweni kwezinto ezintsha kanye nokuthuthukiswa kwezakhiwo zemishini kuya ekusetshenzisweni kwezimboni ezintsha.
Ukuthuthukiswa Kwezinto Ezintsha
Enye yezindlela eziyinhloko zokusebenzisa ubuchwepheshe be-nanotechnology ekusetshenzisweni kwezinsimbi ukuthuthuka kwezinto ezintsha ezinezakhiwo ezinhle kakhulu. Isibonelo esibalulekile ukusetshenziswa kwezinhlayiya ezincane kanye nezinhlanganisela ezincane. Izinhlayiya ezincane ziyizinhlayiya ezilinganiswa esikalini se-nanometer, futhi ukungezwa kwazo ezinsimbini noma kuma-alloy kungathuthukisa izakhiwo eziningi zemishini nezomzimba.
Isibonelo, ukufakwa kwama-nanoparticles e-ceramic njenge-alumina (Al2O3) noma i-zirconia (ZrO2) ku-matrix yensimbi kungathuthukisa ubulukhuni, ukumelana nokuguguleka, kanye nokuzinza kokushisa kwezinto. Ama-alloy ensimbi e-nanocomposite anamandla amakhulu embonini yezindiza kanye neyezimoto, lapho izinto ezilula kodwa ezinamandla zifiseleka kakhulu ekusebenzeni kahle kukaphethiloli kanye nokusebenza kwesakhiwo.
Ukuthuthukiswa Kwezakhiwo Zemishini
I-nanotechnology ivumela nokuthuthukiswa kwezakhiwo zemishini zento ngokusebenzisa izindlela ezahlukene zokuqinisa. Enye indlela ihilela ukufakwa kwama-nanoparticles ezinsimbini ukuze kuqiniswe isakhiwo sazo sokusanhlamvu. Isakhiwo sokusanhlamvu esicolekile singandisa amandla nobunzima bento ngokusebenzisa indlela eyaziwa ngokuthi ukuqinisa imingcele yokusanhlamvu.
Isibonelo, amawele e-nanoscale—amawele e-crystal ku-nanoscale—angasetshenziswa ukwandisa amandla nokuqina kwezinsimbi ezifana nethusi nensimbi ngaphandle kokulahlekelwa ukuqina. Ngaphezu kwalokho, ama-nanosolvents akhiqizwa ngokuqina kwesisombululo esiqinile ngezithasiselo ze-nano, njenge-titanium noma i-nickel, angavimbela ukunyakaza kokuhlukana kwamakristalu ensimbi, ngaleyo ndlela andise amandla ezinto.
Ukumelana Nokugqwala Okukhuphukile
Ukumelana nokugqwala kuyisici esibalulekile ekusetshenzisweni kwensimbi, ikakhulukazi ezindaweni ezinzima njengezimboni zasolwandle noma zamakhemikhali. Kulokhu, ubuchwepheshe be-nano bunikeza ikhambi ngokudala ungqimba oluvikelayo lwe-nanoscale ezindaweni zensimbi.
Ukumboza izindawo zensimbi ngama-nanoparticles afana ne-graphene noma i-silica kunganikeza isivikelo esikhulu kunezindlela zokugqoka ezivamile, ngenxa yezakhiwo zazo ezinhle kakhulu zokuvimbela i-nano. Lezi zingubo zingavimbela ukungena kwezinto ezilimazayo futhi zandise isikhathi eside sezingxenye zensimbi.
Ukuthuthukiswa Kokucubungula Insimbi
I-nanotechnology nayo ithinte izinqubo zokucubungula insimbi kanye nokukhiqiza. Indawo eyodwa ebalulekile amasu okukhipha nokushisela. Ukwengezwa kwezinhlayiya ezincane enkambisweni yokukhipha kunganciphisa usayizi wezinhlamvu kanye nokusatshalaliswa kokuhlukanisa, ekugcineni kuthuthukise ikhwalithi yokukhipha.
Ezinqubweni zokushisela, ama-nanoparticles angasetshenziswa ukuthuthukisa ukuzinza kwe-arc nokunciphisa indawo ethinteke kakhulu ekushiseni, okuholela ekuhlanganeni okuqinile nokufana kakhulu. Ngaphezu kwalokho, ubuchwepheshe be-nanotechnology bungathuthukisa nezinqubo zokushisisa, lapho ama-nanoparticles ensimbi enganciphisa khona izinga lokushisa lokushisisa lama-alloy ensimbi, konge amandla kanye nezindleko zokukhiqiza.
Izinzwa Nokuqapha
I-nanotechnology iphinde ithuthukise amakhono okuqapha nokuzwa ekusetshenzisweni kwensimbi. Izinhlayiya ezincane zemizwa zingasetshenziswa ukuthola izinguquko zokushisa, ukucindezeleka, kanye nomonakalo omncane ezakhiweni zensimbi ngesikhathi sangempela. Isibonelo, izinzwa ezincane ezisekelwe ku-carbon nanotube zingasetshenziswa ezakhiweni zezindiza ukuqapha imifantu noma ukugqwala emaphikweni ezindiza.
Ukuziphilisa
Enye yezindlela ezintsha kakhulu zokusebenzisa ubuchwepheshe be-nanotechnology umqondo wezinto zokuziphilisa. Ngokuhlanganisa ama-nanocapsule aqukethe izinto zokuphulukisa ezinsimbini noma kuma-alloy, lezi zinto zingalungisa ngokuzenzakalelayo umonakalo omncane.
Uma kwenzeka imifantu noma umonakalo, la ma-nanocapsule ayaqhuma, akhulule into yokuphulukisa ephendula futhi ivale umfantu. Lokhu akugcini nje ngokwandisa impilo yenkonzo yezingxenye zensimbi kodwa futhi kunciphisa izindleko zokulungisa kanye nengozi yokwehluleka kwesakhiwo.
Izinto Zamandla kanye Nezikhangisi
Ngaphandle kwezinhlelo zokusebenza zesakhiwo, ubuchwepheshe be-nanotechnology kwezensimbi budlala indima ekuthuthukisweni kwezinto zamandla kanye nama-catalyst. Ama-nanoparticle ensimbi afana ne-platinum ne-palladium asetshenziswa njenge-catalyst ephezulu ekusabeleni okuningi kwamakhemikhali, kufaka phakathi izimboni zokuhluza uwoyela kanye nokukhiqiza amakhemikhali. Ngaphezu kwalokho, ama-nanocomposites ensimbi asetshenziswa ekuthuthukisweni kwamabhethri asebenza kahle kakhulu kanye namaseli kaphethiloli.
Ama-nanoparticle ensimbi angasetshenziswa futhi kubuchwepheshe bokugcina amandla, njenge-supercapacitors namabhethri e-lithium-ion, ngamanethiwekhi e-electrode alungiselelwe ku-nanoscale ukwandisa umthamo wokugcina kanye nesivinini sokushaja.
Izinselele Nezibikezelo Zesikhathi Esizayo
Kodwa-ke, ukuhlanganiswa kwe-nanotechnology ne-metallurgy akunazo izinselelo. Izinkinga zezempilo nokuphepha ngama-nanoparticles, izindleko zokukhiqiza, kanye nokwehluleka ukukhiqiza imiphumela efanayo ezingeni lezimboni ngezinye zezinselelo ezidinga ucwaningo olwengeziwe kanye nentuthuko.
Amathemba esikhathi esizayo e-nanotechnology kwezensimbi aqhakazile. Njengoba ucwaningo kulo mkhakha luqhubeka nokuthuthuka, singalindela ukusungula izinto ezintsha okwengeziwe okuzoguqula indlela esikhiqiza, esicubungula ngayo, futhi sisebenzise ngayo izinsimbi. Kusukela ekusetshenzisweni kwesakhiwo okuqinile nokulula kuya ezintweni zamandla ezisebenza kahle nezisimeme, i-nanotechnology inamandla amakhulu okuguqula kakhulu imboni yezensimbi.
Isiphetho
I-nanotechnology ivule isahluko esisha kwezensimbi, iletha izinzuzo ezibalulekile ngokuthuthukiswa kwezinto ezintsha, izakhiwo zemishini ezithuthukisiwe, ukumelana nokugqwala, kanye nezinqubo zokukhiqiza ezithuthukisiwe. Nakuba kusekhona izinselelo, amathuba anikezwa yi-nanotechnology okuthuthukisa ikhwalithi, ukusebenza kahle, kanye nokusimama kwezensimbi athembisa kakhulu. Ngocwaningo oluqhubekayo kanye nokusungula izinto ezintsha okuqhubekayo, ukusetshenziswa kwe-nanotechnology kwezensimbi kuzosekela kakhulu intuthuko yezobuchwepheshe neyezimboni yesikhathi esizayo.
