Tungsten disulfide (WS2) yochulukira yakhala ikugwiritsidwa ntchito kwa zaka zambiri ngati mafuta owuma chifukwa cha momwe imawonetsera kutsika kocheperako, kukhazikika kwamankhwala, komanso kukhazikika kwamafuta. Mu 1992, zidapezeka kuti mawonekedwe a WS2 adapangitsa kuti azitha kupanga zida za nanotube. Ma nanotubes awa anali zitsanzo zoyamba za WS2 zomwe zimagwiritsidwa ntchito ngati zinthu zotsika kwambiri. Pambuyo pakupezeka kwa njira zosavuta zopangira makina opangira mawotchi kuti azipatula zigawo za 2-D, zinali zotheka kuphunzira za WS2 flakes. Zinawonetsedwa kuti, monga MoS2, kusiyana kwa gulu la WS2 kumasintha kuchoka pagulu lopanda 1.4eV kupita kugawo lachindunji la 2eV posintha kuchoka pazambiri kupita ku 2-D. Chifukwa cha kusiyana kwa gulu, WS2 imawoneka ngati chinthu chosangalatsa kwambiri m'malo ambiri ogwiritsira ntchito. WS2 ili ndi chiwongolero chapamwamba cha / off mu ma transistors ochita kumunda, ma spin osinthika ndi ma polaration a chigwa, kutsekeka kolimba kwa geometrical of excitons, ndi tunable photoluminescence. Kuphatikiza apo, WS2 ikhoza kupangitsa chidwi chochulukirapo m'malo monga ma photodetectors ndi ma multi-junction photovoltaics. Kupatula apo, WS2 imagwiritsidwa ntchito, molumikizana ndi zida zina, monga chothandizira hydrotreating yamafuta amafuta. Lamellar tungsten disulfide imagwiritsidwa ntchito ngati mafuta owuma a zomangira, zomangira, ndi nkhungu pansi pa dzina la Dicronite. Tungsten disulfide (WS2) imagwiritsidwa ntchito ngati mafuta olimba omwe amatha kupirira kutentha kwambiri. Amagwiritsidwanso ntchito ngati mafuta opopera. Tungsten sulfide ntchito ngati chigawo chimodzi cha chothandizira kwa hydrotreating wa mafuta yaiwisi, hydrodesulfurization ndi hydrodenitrification zimachitikira. Imapeza ntchito ngati olimba-boma sekondale lithiamu batire cathodes ndi zina electrochemical zipangizo. Zimapezeka kuti zimapanga ma nanotubes, omwe ndi othandiza kwambiri kuposa ma carbon nanotubes. Kuphatikiza kwa tungsten sulfide ku epoxy resin kumathandizira kumamatira, kulimba kwa fracture komanso kutulutsa mphamvu kwamphamvu. Tungsten sulfide ili ndi mawonekedwe a pseudo 2 dimensional omwe amagwiritsidwa ntchito mumakampani a Petrochemical monga chothandizira cha desulfurization. Tungsten Sulfide nanoparticles akopa chidwi cha kafukufuku chifukwa cha kuthekera kwawo mumafuta olimba a boma; zokutira ndi photocatalysts.
