Graphene Helps To Prevent The Steel From Rusting An Indian researcher and his partner invented a new technology that uses graphene to prevent steel from rusting. Steel rusting is a big problem in the automotive industry. Although covered with paint, it is easy to scratch and chrome is applied to the bumper. The process involves the addition of toxic chemicals To solve this problem, SUNY Buffalo chemistry professor Sarbajit Banerjee and doctoral student Robert Dennis developed a polymer composite containing graphene Graphene is a layer of carbon atoms, it has hydrophobic and strong electrical conductivity. These properties allow steel to reduce the electrochemical reaction of iron rusting iron while it is exposed to water. The two researchers added the composite coating to a varnish, applied it to steel, and then submerged it in salt water. In a typical winter climate, the mixture of salt water and salt and snow is different and a car encounters a car, so it is very effective as a very poor environmental alternative. Initially, the varnished steel sheet only survived a few days in brine. However, by adjusting the concentration and dispersion of added graphene, Banerjee and Dennis can keep the varnish in this environment for a month. Banerjee said he wants to add something to the coating that detects changes in the pH of the water near scratches and reacts with the water in a way that seals the cracks. Although this technology is a long way from commercialization, some large companies in the steel industry are also interested in participating in the study, especially Tata Steel, which has already financed Banerjee's experiment. The two scientists also received $ 50,000 in grants from the New York State Institute for Pollution Prevention. In a press release, Banerjee said the paint can be produced using existing equipment at a local steel plant. Unlike hexavalent chromium, which is used to coat bumpers and some engines, graphene is non-toxic because it is a carbon atom and does not require the use of strong acids and is safe throughout the process. These reasons make graphene a magical material for future electronic components.

Rešetku pomaže u sprečavanju čelika od hrđe Indijski istraživač i njegov partner izmislio novu tehnologiju koja koristi rešetku kako bi se spriječilo čelika od hrđe. Čelični hrđa je veliki problem u automobilskoj industriji. Iako prekriveni bojom, to je lako ogrebotine i krom se primjenjuje na braniku. Proces uključuje dodatak od otrovnih kemikalija Da biste riješili ovaj problem, profesor kemije SUNY Buffalo Sarbajit Banerjee i doktorski student Robert Dennis razvio ujedinjenjem polimera koji sadrži rešetku Rešetku sloj ugljikovih atoma, to su hidrofobne i snažna električna vodljivost. Ova svojstva omogućuju čelika smanjiti elektrokemijskih reakcija željezo hrđa željeza dok je izložena vodi. Dva istraživača dodao kompozitna Obloga za nokte, primijeniti na internet za čelik, a zatim Potopljen u slanoj vodi. U tipične zimske klime, mješavina slane vode i soli i snijeg je drugačiji i auto naiđe auto, tako da je vrlo učinkovit kao vrlo slaba okoliša alternativa. U početku, lakiranih čelični list jedini preživjeli nekoliko dana u slanoj vodi. Međutim, namještanjem koncentracije i disperzije dodano rešetku, Banerjee i Dennis može zadržati lak u ovom okruženju za mjesec dana. Banerjee je rekao da želi nešto doda na premaz koji otkriva promjene u pH vrijednosti vode u blizini ogrebotine i reagira s vodom tako da brtvi pukotine. Iako ova tehnologija je daleko od komercijalizacije, neke velike tvrtke u industriji čelika su također zainteresirani za sudjelovanje u radnoj, pogotovo Tata Steel, koji je već financirao Banerjee je eksperiment. Dva znanstvenika također dobio 50.000 $ u donacijama New York državni zavod za Sprječavanje Onečišćenja. U press release, Banerjee je boja može biti proizveden koristeći postojeće opreme u lokalnim čeličanu. Za razliku od šesterovalentni krom, koji se koristi za kaput neki motora i Branici, rešetku je otrovna jer je atom ugljika i ne zahtijeva korištenje Jake kiseline i sigurno u cijelom procesu. Iz tih razloga bi rešetku čaroban materijal za buduće elektroničke komponente.
