Izinto ze-Nano-Metallic: Intuthuko Nezinselele

October 13, 2022

Eminyakeni engaphezu kwengu-40 edlule, ososayensi babona ukuthi izakhiwo ezihlaselwe ezintweni zangempela azinakwa. Imiphumela eminingi esanda kutholwa ngokomzimba, njengokushintshwa okuthile kwesigaba, imiphumela kasayizi we-quantum, kanye nezinto zokuhamba ezihlobene, zenzeka kuphela kuma-solids aqukethe iziphambeko. Eqinisweni, uma indawo ye-crystal yesilinganiso se-polycrystal esilinganisweni (ububanzi obusanhlamvu noma isizinda noma ububanzi befilimu) ifinyelela ubude obuthile bokucaciswa (njengendlela yamahhala, ubude bokuhlangana, ubude bokuhlangana, ukusebenza kwe Izinto zokwakha ngeke zincike ekuthengeni ekuxhumaneni kwe-athomu, kuthonywa ukuncishiswa kobukhulu bayo, isilinganiso kanye nokulawulwa okuphezulu kokulawula. Ngenxa yalokhu, iHhotsheitcr ikholelwa ukuthi uma ama-polycrystals osayizi we-nanometer angaguqulwa, okungukuthi, izinto ezihlanganiswe ngokuningi kwezindawo ezingenazo zokuhlangana [isib. Ku-VOL.) Amakristalu], isakhiwo sawo azohluka kakhulu ku-polycrystal ejwayelekile (usayizi wokusanhlamvu omkhulu kune-LMM) noma ingilazi (i-oda le-2nm), elibizwa nge- "nanocrystalline izinto". Kamuva, isifunda se-crystal noma ezinye izinto ubude obuhle obukhona ebangeni le-nanometer (ngaphansi kwe-100nn) zichazwa kabanzi ngokuthi "ama-nanomatadium" noma "izinto zokwenziwa". Ngenxa ye-microscucture yabo ehlukile kanye nezakhiwo ezihlukile, ama-nanomatadium adonsele ukunakwa okukhulu emphakathini wezesayensi futhi abe yindawo yokucwaninga eshisayo emhlabeni wonke. Izinkambu zazo zihilela i-physics, i-chemistry, i-biology, ama-microelectronics nezinye iziyalo eziningi. Njengamanje, incazelo ebanzi yama-nanomatadium ikakhulukazi ifaka:

L) ihlanzekile noma ingubo yensimbi yensimbi, amafilimu e-semiconductor noma ama-polymer;

2) ama-superlattices wokufakelwa kanye nezakhiwo ze-quantum;

3) semi-crystalline polymer nengxube ye-polymer;

4) ama-nanocrystals kanye nama-nanocrystals;

5) Ama-Nanocomos ahlanganiswe ama-Metallic Bonds, izibopho ezingejwayelekile noma izingxenye zamangqamuzana.
