Engxoxweni ende phakathi kwabantu nezinto zokuzivikela,izitsha zobumba ze-silicon carbideiphendula esiphakamisweni saphakade sokuvikelwa kokuphepha ngezwi eliyingqayizivele. Lesi sitsha sobumba esibonakala sivamile esimpunga-mnyama senza inguqulo yesimanje yendaba "yokuguquguquka ngobumnene ngokumelene nobunzima" emikhakheni esezingeni eliphezulu njengemboni yezempi kanye nezindiza.
Ikhodi yokuvikela ye-silicon carbide ceramics itholakala ezweni layo elincane kakhulu. Uma ikhuliswa ibe yi-nanoscale, izakhiwo eziningi ezinhle ze-tetrahedral zifana namabhulokhi e-Lego ahlanganiswe kahle, futhi le nethiwekhi yemvelo enezinhlangothi ezintathu inika izinto ubulukhuni nokuqina okungavamile. Lapho inhlamvu ithinta indawo, lesi sakhiwo singasebenza “njengesiphethu sama-molecule”, sibeke futhi sincibilikise amandla okushaya, sigweme ukugoba nokuguquka kwezikhali zensimbi zendabuko futhi sinqobe ubuthakathaka bezinto zobumba ezivamile ezivame ukuqhekeka.
Uma kuqhathaniswa nezinto zendabuko ezingangenwa yizinhlamvu, lolu hlobo olusha lwe-ceramic lubonisa "ubuntu obubili" obuhlukile. Ubulukhuni balo bungaphikisana nobedayimane, kodwa isisindo salo siyingxenye eyodwa kwezintathu kuphela sensimbi. Lesi sici "esilula njengensiba" senza imishini yokuvikela ikwazi ukufeza intuthuko yangempela ekukhanyiseni. Okumangaza nakakhulu ukuthi ngemva kokubekezelela ukushaqeka okukhulu, ayishiyi ukucindezeleka kwangaphakathi okubulalayo njengoba kwenza izinsimbi, futhi lesi sici "sokungathetheleli" sithuthukisa kakhulu ukuthembeka kwezinto.
Elabhorethri, ipuleti le-silicon carbide ceramic lihlolwa nge-ballistic. Lapho i-projectile isondela ngesivinini samamitha angu-900 ngomzuzwana, izinhlansi eziqhuma lapho zithintana zifana nombukiso weziqhumane ezweni elincane kakhulu. Ngalesi sikhathi, ubuso be-ceramic buqala ukukhombisa "amakhono abo e-Tai Chi": okokuqala, ngokuqina okuphezulu kakhulu kobuso, i-projectile iyafiphala; bese, isakhiwo sezinyosi sisakaza igagasi lokushaqeka kuzo zonke izinhlangothi; ekugcineni, ngokuguqulwa kwepulasitiki kwezinto ze-matrix, amandla asele ayamuncwa ngokuphelele. Le ndlela yokuzivikela yengqimba ngengqimba ichaza ngokucacile ukuhlakanipha kobuchwepheshe besimanje bokuvikela.
Ososayensi bezinto ezibonakalayo basahlola amathuba engeziwe: ngokuklama kwe-bionics ukulingisa isakhiwo esihlanganisiwe samagobolondo, ukufaka imicu yokuzwa ehlakaniphile ku-ceramic matrix, kanye nokuzama ukwenza izinto zibe namakhono okuzilungisa. Lokhu kusungula izinto ezintsha akugcini nje ngokuqhubekisela phambili ubuchwepheshe bokuvikela kodwa futhi kuchaza kabusha incazelo yesimanje "yokuphepha".
Kusukela ezivikelweni zethusi zamasosha asendulo kuya ezitsheni ze-nano ceramic zanamuhla, ukuphishekela kwabantu ukuvikelwa kokuphepha akukashintshi. Indaba yokuthuthukiswa kwezitsha ze-silicon carbide isitshela ukuthi: Ukuvikelwa okuqine kakhulu kuvame ukuvela emithethweni yemvelo emihle kakhulu, futhi impumelelo kwisayensi yezinto ezibonakalayo empeleni iwumdanso omuhle onemithetho yemvelo.
