I-Copper yeyona nto isebenzayo ekulweni neentsholongwane kwiindawo eziphezulu.
Kangangamawaka eminyaka, kudala ngaphambi kokuba bazi ngeentsholongwane okanye iintsholongwane, abantu bebesazi ngamandla okubulala iintsholongwane ekopolo.
Ukusetyenziswa kokuqala kwekopolo njengeyeza lokubulala usulelo kuvela kwiPapyrus kaSmith, uxwebhu lwezonyango oludala kakhulu kwimbali.
Ukususela kwiminyaka yoo-1600 ngaphambi kwexesha likaYesu, amaTshayina ayesebenzisa iingqekembe zobhedu njengeyeza lokunyanga iintlungu zentliziyo nesisu kunye nezifo zesinyi.
Kwaye amandla ekopolo ahlala ixesha elide. Iqela likaKeevil lijonge iireyili ezindala kwiGrand Central Terminal eNew York City kwiminyaka embalwa eyadlulayo. "Ikopolo isasebenza njengoko yayinjalo ngomhla eyafakwa ngawo kwiminyaka engaphezu kwe-100 eyadlulayo," utshilo. "Le nto ihlala ixesha elide kwaye isiphumo sokulwa neentsholongwane asipheli."
Isebenza njani kanye kanye?
Indlela eyenziwe ngayo i-atom yeCopper iyinika amandla okubulala angaphezulu. ICopper ine-electron ekhululekileyo kwiqokobhe layo elingaphandle le-orbital lee-electron ezithatha inxaxheba ngokulula kwiimpendulo zokunciphisa i-oxidation (nto leyo eyenza isinyithi sibe ngumqhubi olungileyo).
Xa intsholongwane ifika kubhedu, ii-ion ziqhumisa i-pathogen njengokuhlasela kwee-missile, zithintela ukuphefumla kweeseli kunye nokubhoboza imingxunya kwi-membrane yeseli okanye i-viral coating kwaye zenze ii-free radicals ezikhawulezisa ukubulala, ingakumbi kwiindawo ezomileyo. Okubaluleke kakhulu, ii-ion zifuna kwaye zitshabalalise i-DNA kunye ne-RNA ngaphakathi kwibhaktheriya okanye intsholongwane, zithintela utshintsho oludala ii-superbugs ezinganyangekiyo ngamayeza.
Ngaba i-COVID-19 ingasinda kwiindawo zobhedu?
Uphononongo olutsha lufumanise ukuba i-SARS-CoV-2, intsholongwane ebangela ubhubhane we-coronavirus, ayisasuleli kwi-copper kwiiyure ezi-4, ngelixa inokuphila kwiindawo zeplastiki iiyure ezingama-72.
I-Copper ineempawu zokulwa neentsholongwane, oko kuthetha ukuba inokubulala iintsholongwane ezifana neebhaktheriya kunye neentsholongwane. Nangona kunjalo, i-microorganism kufuneka idibane ne-copper ukuze ibulawe. Oku kubizwa ngokuba "kukubulala abantu abanxibelelanayo."
Ukusetyenziswa kwekopolo elwa namagciwane:
Enye yezona ndlela ziphambili zokusetyenziswa kwekopolo zisezibhedlele. Iintsholongwane zibonakala kakhulu kwigumbi lesibhedlele – iibhedi, amaqhosha okufowuna, iingalo zesitulo, itafile yetreyi, igalelo ledatha, kunye nepali ye-IV – kwaye endaweni yazo kufakwa izinto zekopolo.
Xa kuthelekiswa namagumbi enziwe ngezinto zemveli, bekukho ukwehla kwe-83% kumthwalo weebhaktheriya kwiindawo ezikumagumbi aneenxalenye zobhedu. Ukongeza, amazinga osulelo lwezigulane ancitshiswe ngama-58%.
Izinto zobhedu zingaba luncedo njengeendawo zokulwa neentsholongwane ezikolweni, kwimizi-mveliso yokutya, kwiihotele zeeofisi, kwiindawo zokutyela, kwiibhanki njalo njalo.
