Faʻataʻitaʻiga o mea lelei taua
Faʻataʻitaʻiga o mea leaga taua

Ua valaauina faʻatamaia i le faʻagasologa o vailaʻau o faʻatelevave pe faʻatelegese se vailaʻau, mai le faʻaopopoina o se vailaʻau poʻo se elemeni, uma faigofie ma tuʻufaʻatasia, e suia taimi tali atu e aunoa ma le afaina ai o le natura o le mulimuli oloa o le tutusa ma, e le gata i lea, aunoa ma le leiloa o lona lava tele i le gaioiga, lea e tupu i gaioiga.

O lenei elemeni ua taʻua vaega taua. Soʻo se vailaʻau tali atu ei ai se talafeagai talafeagai taua, lea e mafai ona faʻatelevave, faʻateleina pe faʻaleleia atili (mafuaʻaga lelei), pe faʻasolosolo lemu, faʻaititia ma faʻavaivai (mafuaʻaga le lelei) lau faʻagasologa. Ole mea mulimuli e masani ona taʻua ole mea e taofi ai mea.

Faʻataʻitaʻiga o mea lelei taua

Vevela. Tele vailaʻau tali atu mafai ona faʻatelevaveina aunoa ma suia latou oloa, na o le faʻateleina le vevela o le auala tali atu. Mo lenei mafuaʻaga le faʻavasegaina o le mataupu e tupu vave i le teropika.
Enzimme. E masani lava ona vavaeeseina e le tino o mea ola, o le enzymes e taua tele le taua o le gaioiga, faʻatelevaveina gaioiga taua, pe a fai e tupu na o latou, e manaʻomia le vevela e masani ona le mafaia ma le ola. (matamata: digestive enzymes)
Palladium faʻatonu. Mo taʻavale e faʻaaogaina le penisini e le faʻaulufaleina, o paipa o loʻo iai palaladium poʻo le platinum i ni vaega ninii e faʻataʻitaʻiina i le faʻamaeʻaina o taʻavale, e mafai ona latou faʻatupuina le faʻafouina o le carbon monoxide ma isi kasa oona o loʻo mu, faʻatagaina e faʻaititia ai. vailaʻau itiiti le mataʻutia i le faʻamaumauga o taimi.
Fluorine mafuaʻaga. Latou faʻatelevaveina le pala o le osone (O₃→ O + Oe₂) i le okesene, o se tali e masani ona tuai. Lenei o le faʻafitauli o aerosols ma pusaaisa na faʻasaʻoloto CFC i le ea: latou faʻatupuina le osone vaega i lenei uiga.
Magnesium dioxide (MnO₂). O se vaega taua i le pala o le Hydrogen Peroxide poʻo le hydrogen peroxide (2H₂PO O LE₂→ 2H₂O + Oe₂) i le vai ma le okesene.
Limasene. Faʻaaogaina i le hydrogenation o fualaʻau suauʻu, e maua ai margarine, ona o lenei uʻamea faʻatelevaveina le gaioiga o le mauaina o lipid tumu.
Siliva. Polycrystalline siliva ma nanoporose o ni saoasaoa aoga o carbon dioxide (CO₂) i le electrocatalysis.
Alumini chloride. Tagata faigaluega i le alamanuia alamanuia petrochemical e faʻavave ai le gaosiga o gaosia resins poʻo lubricants, aunoa ma le suia o le maaleale natura o hydrocarbons i le fesili, talu ai ona acidic ma masani meatotino i le taimi e tasi (amphoteric vailaʻau).
O le uʻamea. E faʻaaogaina o se mea e faʻatupuina i le Haber-Bosch gaioiga e maua mai ai le amonia mai le hydrogen ma le nitrogen.
Moli UV. Malamalama uila, faʻatasi ai ma le vaega taua, fausiaina photocatalysis: o le televave o se vailaʻau tali mai i le galuega a se faʻatupuina faʻagaoioia e le malamalama malosiaga o ultraviolet.

Faʻataʻitaʻiga o mea leaga taua

Vevela. E pei lava o le faʻateleina o le vevela faʻavaveina le faiga o vailaʻau, o le faʻaititia e faʻatuai ai latou. Lenei o le faʻavae o le pusaaisa, mo se faʻataʻitaʻiga, e faʻaumiumi ai le ola o meaʻai e ala i le tuʻuina i le maualalo o le vevela.
Citric acid. O le acid o le tipolo ma isi fua o le moli e faatelegese ai le faʻatinoina ole oxidation o le mea faatulagaina.
Enzim taofi. O meaola niniʻi e fusifusia i enzymes ma faʻaititia ai a latou gaioiga, e taofi ai le faʻatupuina o vailaʻau poʻo vailaʻau. E masani ona faʻaaogaina e tau ai meaola ninii pathogenic, taofia nisi o auala autu mo lona toe gaosia.
Potassium chlorate. Faʻaaogaina i lanumoana gaioiga, lea magnetite uʻamea ua ufiufiina e faʻatelegese pe puipuia ai lona pala auala.
Sorbic acid. Faʻasao masani na faʻaaogaina i le vaega o meaʻai e faʻatelegese ai le pala o meaʻai.
Tetraethyl lead. I le taimi nei ua leai se kesi, o lenei vailaʻau na faʻaaogaina o se antiknock, o lona uiga, e puipuia ai le pa muamua.
Fuafua acid. O le leai se lanu, mataʻutia suavai ma le manogi manogi, e talafeagai mo le faʻasaoina o meaʻai, meaʻai ma vailaʻau vailaʻau, ona o se mamana antifungal ma suia tupuola faʻatamaina.
Sulfur ma mafuaʻaga. O nei vaega o loʻo avea ma mea e taofiofi ai le lelei faʻamaʻi o le pauta platinum poʻo le limasene i le tali atu i le hydrogenation. O le aliaʻe mai o le teio o le sulfur taofi le aafiaga ma le tali atu toe foi i lona saoasaoa masani.
Hydrocyanic (poʻo le prussic) acid. Maualuga oona, lona aʻafiaga i manu poʻo tagata faʻalavelaveina le gaioiga o le tele metalloenzymes, faʻapea ona puipuia sela faʻaaogaina ma mafua ai le oti i ni nai minute.
Mercury, phosphorus, poʻo arsenic ausa. O nei vailaʻau faʻaleaogaina atoa le gaioiga o platinum asbestos i le gaosiaina o le sulfuric acid, o loʻo avea o se malosi taofiofia.
