I-Tungsten disulfide (WS2) ngobuningi isetshenziswe iminyaka eminingi njengesithambiso esomile ngenxa yokuthi ikhombisa kanjani izakhiwo ze-coefficient ephansi yokungqubuzana, ukuqina kwamakhemikhali okuphezulu, nokuzinza kwe-thermal. Ngo-1992, kwatholakala ukuthi ukwakheka kwe-WS2 kwenze ukuthi ikwazi ukwenza izakhiwo ze-nanotube. Lawa ma-nanotubes abeyizibonelo zokuqala ze-WS2 ezisetshenziswa njengento enobukhulu obuphansi. Ngemva kokutholakala kwezindlela ezilula zokucwenga zemishini ukuze kuhlukaniswe izingqimba ezilodwa zezinto ezingu-2-D, kwakungenzeka ukutadisha izakhiwo ze-WS2 flakes. Kwaboniswa ukuthi, njenge-MoS2, i-band-gap ye-WS2 iyashintsha isuka kugebe yebhendi engaqondile engu-1.4eV iye endaweni eqondile ye-band-gap ye-2eV lapho ishintsha isuka kokuningi iye kwengu-2-D. Ngenxa ye-band-gap yayo, i-WS2 ibonakala njengento ethakazelisa kakhulu ezindaweni eziningi zohlelo lokusebenza. I-WS2 inezinga eliphezulu lokuvula/lokuvala kuma-transistors asebenza ensimini, i-spin elawulekayo kanye ne-valley polarisation, ukuvalelwa okuqinile kwejiyomethri kwama-excitons, kanye ne-photoluminescence ephathekayo. Ukwengeza, i-WS2 ingaholela ekwandeni kwesithakazelo ezindaweni ezifana nama-photodetectors kanye nama-photovoltaics e-multi-junction. Ngaphandle kwalokho, i-WS2 isetshenziswa, ngokubambisana nezinye izinto, njenge-catalyst for hydrotreating of crude oil. I-Lamellar tungsten disulfide isetshenziswa njengesithambiso esomile sokubopha, ama-bearings, kanye nezibunji ngaphansi kwegama lomkhiqizo i-Dicronite. I-Tungsten disulfide (WS2) isetshenziswa njengesithambiso esiqinile esikwazi ukumelana namazinga okushisa aphezulu. Ibuye isetshenziswe njenge-lubricant yesifutho. I-Tungsten sulfide isetshenziswa njengengxenye ye-catalysts ye-hydrotreating kawoyela ongahluziwe, i-hydrodesulfurization kanye nokusabela kwe-hydrodenitrification. Ithola uhlelo lokusebenza njenge-solid-state secondary lithium battery cathodes namanye amadivaysi e-electrochemical. Kutholakala ukuthi yakha ama-nanotubes angaphili, okuyi-ejenti yokuqinisa kangcono kunama-carbon nanotubes. Ukwengezwa kwe-Tungsten sulfide ku-epoxy resin kuthuthukisa ukunamathela, ukuqina kokuphuka kanye nezinga lokukhululwa kwamandla. I-Tungsten sulfide inokwakheka kwe-pseudo 2 dimensional esetshenziswa embonini ye-Petrochemical njenge-catalyst ye-desulfurization. Ama-nanoparticles e-Tungsten Sulfide adonse isithakazelo socwaningo ngenxa yamandla awo kuzinto zokuthambisa ezisezingeni eliqinile; ama-coatings nama-photocatalysts.
