EChina, yabizwa ngokuthi "Qi," uphawu lwezempilo. EGibhithe kwabizwa ngokuthi "Ankh," uphawu lokuphila okuphakade. KwabaseFenike, ireferensi yayihlobene ne-Aphrodite - unkulunkulukazi wothando nobuhle.
Lezi zimpucuko zakudala zazibhekisele kwithusi, okubonakalayo okuthi amasiko emhlabeni wonke abonakale sengathi kubalulekile empilweni yethu iminyaka engaphezu kuka-5, o00. Lapho umkhuhlane, ama-bacterium afana ne-E. Coli, ama-superbugs afana ne-MRSA, noma ngisho nama-coronaviruseses umhlaba ezindaweni ezinzima kakhulu, angaphila kuze kube kwezinsuku ezine kuya kwezihlanu. Kepha lapho befika ethuneni, kanye ne-Copper Alloys njengethusi, baqala ukufa kungakapheli imizuzu futhi ababonakali kungakabonakali kungakapheli amahora.
"Sibonile amagciwane avele aqhakaze nje," kusho uBill Keevil, uprofesa wezokunakekelwa kwempilo kwezemvelo e-University of Southampton. "Bafika ethuneni futhi bamane babalahle." Akumangalisi ukuthi eNdiya, abantu bebephuze izinkomishi zethusi zezinkulungwane zeminyaka. Ngisho lapha e-United States, umugqa wethusi uletha amanzi akho okuphuza. I-Copper izinto zemvelo, ezingenamqondo, eziphilayo. Kungazenzela ubuqili endaweni yayo ngaphandle kwesidingo sikagesi noma nge-bleach.
I-Copper yaqhakaza ngesikhathi sokuguqulwa kwezimboni njengento yezinto ezibonakalayo zezinto, ukulungiswa, kanye nezakhiwo. I-Copper isasetshenziswa kabanzi kumanethiwekhi Amandla - Imakethe yethusi empeleni iyakhula ngoba impahla ingumqhubi ophumelelayo. Kepha okuqukethwe kukhishwe ngaphandle kwezicelo eziningi zokwakha ngegagasi lezinto ezintsha ezivela ngekhulu lama-20. Amapulasitiki, ingilazi efihlwe, i-aluminium, nensimbi engenacala yizinto zokwakha zesimanje - ezisetshenziselwa yonke into kusuka kwimikhiqizo ye-Apple. Izinduku zomnyango wethusi kanye nezindawo ezinama-handrails ziphume ngesitayela njengabakhi bezakhiwo nabaklami bakhetha izinto ezibukeka zibukeka (futhi ezivame ukushibhile).
Manje uKeevil ukholelwa ukuthi sekuyisikhathi sokubuyisa ithusi ezindaweni zomphakathi, kanye nezibhedlela ikakhulukazi. Lapho sibhekene nekusasa elingenakugwenywa eligcwele ama-pandemics omhlaba, kufanele sisebenzise ithusi ekunakekelweni kwezempilo, ukuhamba komphakathi, kanye namakhaya ethu. Futhi ngenkathi sekwephuze kakhulu ukumisa i-Covid-19, akukusekuseni kakhulu ukuba ucabange ngobhubhane lwethu olulandelayo.Izinzuzo zethusi, ezinqunyelwe
Bekufanele sikubone kuza, futhi empeleni, othile wenza.
Ngo-1983, umcwaningi wezokwelapha uPyllis J. Kuhn wabhala nokugxeka kokuqala kokunyamalala kweCopper ubengabonile ezibhedlela. Ngesikhathi sokuvivinya umzimba ngenhlanzeko eHamot Medical Center ePittsburgh, abafundi bachitha indawo ehlukahlukene esibhedlela, kufaka phakathi amathoyilethi izitsha kanye namathanga ezindlu zangasese. Wabona ukuthi izindlu zangasese zazihlanzekile amagciwane, kanti ezinye zokulungiswa zazingcolile futhi zikhula ngamagciwane ayingozi lapho zivunyelwe ukwanda ngamapuleti e-agar.
"Kumabala futhi kukhanyise i-doorknobs engagqwali ye-doorknobs kanye namapuleti acwebezela abukeke ehlanzekile emnyango wesibhedlela. Ngokuphambene nalokho, i-doorknobs kanye namapuleti e-tarnised zethusi abukeka engcolile futhi angcolisiwe, "kubhala ngaleso sikhathi. "Kepha noma ngabe kubuhlungu, ithusi - imvamisa ithusi elingama-67% kanye nama-33% iZinc- [libulala insimbi engagqwali], kuyinsimbi engagqwali - i-chromium engama-88% -
Ekugcineni, wasonga iphepha lakhe ngesiphetho esilula ngokwanele kulo lonke uhlelo lwezempilo okufanele lululame. "Uma isibhedlela sakho sivuselelwa kabusha, zama ukugcina i-hardware yakudala yethusi noma iphinde yaphinda; Uma une-hardware yensimbi engenasici, qiniseka ukuthi kuvinjelwe amagciwane nsuku zonke, ikakhulukazi ezindaweni zokunakekelwa okubucayi. "
Emashumini eminyaka kamuva, futhi kuvunywa ngemali evela kwi-Copper Development Association (Iqembu lezohwebo lezimboni), iKeevil iqhubekele phambili ucwaningo lukaKuhn ngokuqhubekayo. Ukusebenza ngelebhu yakhe namanye amagciwane angesatshwa kakhulu emhlabeni, ukhombisile lokho akugcinanga kuphela ukuthi ithusi libulala ngempumelelo amagciwane; Ibuye ibubula amagciwane.
Emsebenzini kaKeevil, ubopha ipuleti yethusi etshwaleni ukuze inzalo. Ngemuva kwalokho wasidinca ube yi-acetone ukuze ususe noma yimaphi amafutha angaphandle. Ngemuva kwalokho wehla kancane nge-pathogen ebusweni. Ngezikhathi zomile. Isampula sihlala kunoma yikuphi kusuka imizuzu embalwa ziye ezinsukwini ezimbalwa. Ngemuva kwalokho uyakunikisa ebhokisini eligcwele ubuhlalu bengilazi noketshezi. Ubuhlalu buhlubula amagciwane namagciwane ku-ketshezi, futhi uketshezi lungahlelwa khona ukuthola ubukhona babo. Kwezinye izimo, uthuthukise izindlela ze-microscopy ezimvumela ukuthi azibuke - futhi aqoshwe - ama-pathogen abhujiswa yi-zethusi lapho kushaya khona indawo.
Umphumela ubukeka njengoMagic, uthi, kepha okwamanje, izehlakalo ekudlaleni kuqondakala kahle isayensi. Lapho leli gciwane noma amagciwane eshaya ipuleti, ligcwele ama-ion. Lawo ma-ion angena kumaseli namagciwane afana nezinhlamvu. Ithusi aligcini nje nje ukubulala la magciwane; Kuyababhubhisa, kwehle kuze kube ama-acid ama-nucleic, noma imidwebo yokuzala, ngaphakathi.
UKeevil uthi: "Alikho ithuba lokuguqulwa kwezakhi zofuzo [noma kwemvelo] ngoba zonke izinhlobo zofuzo ziyachithwa. "Leyo enye yezinzuzo zangempela zethusi." Ngamanye amagama, ukusebenzisa i-Copper akusondeli, kusho, ukuchaza ama-antibiotics. Kungumqondo omuhle nje.
Ekuhlolweni kwangempela komhlaba, ithusi lifakazela ukuthi lawo lalo ngaphandle kwelebhu, abanye abacwaningi balandele ukuthi ithusi lenza umehluko lapho besetshenziswa emibhedeni yezokwelapha engokoqobo, kodwa futhi basebenza lapho kusetshenziswa ama-post of teams ezibhedlela ezintathu, futhi kusetshenziswa Amanani okutheleleka ngokutheleleka ngo-58%. Kwenziwa isifundo esifanayo ngonyaka we-2016 ngaphakathi kweyunithi yokunakekelwa kwezingane, eyayivutha ukuncishiswa okuhlaba umxhwele ngezinga lokutheleleka.
Kepha kuthiwani ngezindleko? I-Copper ihlala ibiza kakhulu kunepulasitiki noma i-aluminium, futhi imvamisa i-pricier enye indlela. Kepha uma unikezwe ukuthi izifo ezithwelwe izibhedlela zibiza uhlelo lokunakekelwa kwezempilo njengoba nje ama- $ 45 billion ngonyaka - kungasaphathwa ukubulala abantu abaningi abangaba ngu-90,000 - izindleko zokuthuthukisa zethusi zinganakwa ngokuqhathanisa.
UKeevil, ongasatholi imali embonini yethusi, ukholelwa ukuthi umthwalo wemfanelo uwela kumakhi wezakhiwo ukukhetha ithusi emisebenzini emisha yokwakha. I-Copper yayingowokuqala (futhi kuze kube manje kuyinto yokugcina) yensimbi yensimbi evunyelwe yi-EPA. (Izinkampani embonini yesiliva zizamile futhi zehlulekile ukuzifuna kwakungu-antimicrobial, empeleni oholele ku-EPA Fine.) Amaqembu embonini embonini abhalisele ama-alloys angaphezu kuka-400 nge-EPA kuze kube manje. "Sikhombisile ukuthi iCopper-Nickel yinhle njengethusi ngokubulala amagciwane namagciwane," kusho yena. Futhi i-nickel yethusi ayidingi ukubukeka njengecilongo elidala; Akunakuphikwa ngensimbi engenasici.
Ngokuqondene nezakhiwo zezwe lonke ezingavuselelwa ukuklebhula ukulungiswa kwamathusi amadala, i-keevil inesiqephu sezeluleko: "Ungazisusi, noma yini oyenzayo. Lezi yizinto ezinhle kakhulu ozitholile. "
