 Ọdịdị nke galik

Nri na ísì galik bụ n'ihi mmanụ, nke na-acha odo odo organosulfur compound S-Allyl prop-2-ene-1-sulfinothioate, nke a na-akpọkarị Allicin. Garlic ọhụrụ nwere obere ísì ruo mgbe a ga-egbutu ya ma ọ bụ kụrisịa ya.  na-emepụta allicin site na alliin (nke sitere na amino acid cysteine) site na enzyme alliinase. Allicin anaghị akwụsi ike  na-agbaji iji mepụta ihe ndị ọzọ dị ka diallyl sulfides. Ngwakọta ndị a na-enye aka n'isi galik ọhụrụ. Mgbe ha nọ n'aka, ihe ndị a nwere ike ịghọ ihe ndị ọzọ na-esi ísì ụtọ, gụnyere sulfuric acid, n'ihu mmiri.

Steel bụ ngwakọta nke e ji ígwè gwakọta na carbon mee. A na-eji ígwè na-enweghị ntụpọ agwakọta ya na ọ dịkarịa ala 10.5% chromium, na mgbe mgbe ihe ndị ọzọ dị ka nickel na molybdenum, wdg. A na-agbakwunye Chromium iji mee ka ọ na-eguzogide nchara. Steels na-enweghị ntụpọ nke na-eguzogide corrosion na oxidation na-achọkarị ihe karịrị 11% chromium. A na-agbakwunye Nickel iji mee ka ihe na-eguzogide corrosion dịkwuo elu, ma chebe ya pụọ na ọnọdụ gburugburu ebe obibi siri ike. Enwere ike itinye Molybdenum iji zere pitting ma ọ bụ scarring. Enwere ike imeziwanye ihe n dị na ígwè na-enweghị ntụpọ maka iji ya eme ihe pụrụ iche site na ịgbakwunye ihe ndị ọzọ, dịka titanium, vanadium na ọla kọpa. [1]
