Saina Fa'atau oloa siiatoa tau CAS 12138-09-9 Tungsten Disulfide Tau WS2 Pa'u High-Entropy Alloys

Tungsten disulfide (WS2) i le tele ua faʻaaogaina mo le tele o tausaga e avea o se lubricant mago ona o le auala e faʻaalia ai meatotino o le maualalo o le feteʻenaʻiga, mautu kemisi maualuga, ma le mautu vevela. I le 1992, na maua ai o le fausaga o le WS2 na mafai ai ona fausia ni fausaga nanotube. O nei nanotubes o faʻataʻitaʻiga muamua ia o le WS2 o loʻo faʻaaogaina e fai ma mea maualalo. Ina ua maeʻa le mauaina o auala faʻapitoa faʻainisinia faigofie e faʻamavaeina ai se tasi vaega o mea 2-D, na mafai ona suʻesuʻeina meatotino o WS2 flakes. Na faʻaalia, e pei lava o le MoS2, o le fusi-gap o le WS2 e suia mai le vaʻavaʻavaʻavaʻa o le 1.4eV i se vaʻa tuusaʻo o le 2eV pe a suia mai se mea tele i se mea 2-D. Ona o lona fusi-gap, WS2 ua vaʻaia o se mea sili ona manaia mo le tele o vaega o faʻaoga. O le WS2 o lo'o i ai se fua fa'atatau maualuga i luga o / ese i transistors-aafiaga o fanua, fa'atonutonuina le milo ma le valley polarisation, malosi fa'agata fa'atusa o excitons, ma tunable photoluminescence. E le gata i lea, WS2 e mafai ona taʻitaʻia ai le faʻateleina o le fiafia i vaega e pei o photodetectors ma multi-junction photovoltaics. E le gata i lea, o le WS2 o loʻo faʻaaogaina, faʻatasi ma isi mea, e fai ma faʻamalosi mo le faʻaogaina o le suauʻu mama. Lamellar tungsten disulfide o loʻo faʻaaogaina e avea o se lubricant mago mo faʻamau, bearings, ma faʻailoga i lalo o le igoa igoa Dicronite. Tungsten disulfide (WS2) o loʻo faʻaaogaina e avea o se lubricant malosi e mafai ona tatalia le maualuga o le vevela. E fa'aaogaina fo'i e fai ma pulu lubricant. Tungsten sulfide o loʻo faʻaaogaina e avea o se vaega o faʻamalosi mo le faʻaogaina o le suauʻu mama, hydrodesulfurization ma hydrodenitrification reactions. E maua ai le fa'aogaina e pei o cathodes maa lithium lua ma isi masini eletise. E maua ai e fausia ai nanotubes inorganic, lea e sili atu le faʻamalosia o mea faʻamalosi nai lo carbon nanotubes. Tungsten sulfide faʻaopoopoga i le epoxy resin e faʻaleleia ai le pipii, gau gau ma faʻalavelaveina le fua o le malosi. Tungsten sulfide o loʻo i ai se faʻailoga 2 dimensional fausaga faʻatasi ma faʻaoga i le Petrochemical alamanuia e avea o se faʻamaʻi faʻamaʻi. Tungsten Sulfide nanoparticles ua maua ai suʻesuʻega suʻesuʻega ona o lo latou gafatia i lubricants solid-state; fa'apipi'i ma photocatalysts.
