Yintoni iMolybdenum Disulfide?

I-molybdenum sulfide, i-chemical compound, ifumaneka ngokwemvelo ngendlela yeminerali ebizwa ngokuba yi-molybdenite. Le khompawundi ineendlela ezahlukeneyo zokusetyenziswa kunye nemisebenzi njenge-lubricant. Iimpawu zayo zokuthambisa zivela kwisakhiwo salo samachiza, esibonakaliswe ngokuqulunqwa kweebhondi zetsimbi-sulfure. Ezi zibophelelo zinokutyibilika kwaye zenziwe kwakhona xa imikhosi yokucheba isetyenziswa, idala ifilimu kumphezulu wesinyithi.

I-Molybdenum sulfide (i-TMDC) yi-dichalcogenide yentsimbi eguqukayo. Ihlelwa kumaqela etafile yeperiodikhi 4-16. Ifomula yekhemikhali yekhompawundi yi-MoS2. Uphawulwa ngolwakhiwo olulodwa lwekristale olunemigangatho emithathu yeplana etyibilika omnye komnye phantsi kwamandla aphantsi okucheba. Oku kubangele i-coefficient ephantsi ye-friction, okanye isigxina, esimalunga ne-0.025.

Imolybdenum disulfide iqhele ukusetyenziselwa ukuthambisa kwiindawo ezirhabaxa. Isebenza ngokufanelekileyo ekuboneleleni nge-lubrication kwiindawo ezinzima, nangona kukho i-oxidation. Ukongeza, kunciphisa ukuthambekela kwesinyithi ukuwohloka. I-Molybdenum disulfide inokumelana okuphezulu nokubola kunye namasuntswana amakhulu anyusa amandla esinyithi ukuthwala imithwalo enzima.

Imolybdenum diokside sisithambisi esomileyo, esiqinileyo sefilimu eneempawu ezizodwa. Ingasetyenziselwa inani leenjongo, kubandakanywa izicelo zoxinzelelo oluphezulu. Isenokusetyenziswa ukunciphisa ukukhuhlana kwizicelo zesantya esiphezulu, kwaye inokumelana namaqondo obushushu agqithisileyo.

I-MoS2 ineempawu ezithembisayo zezixhobo zefoto, kunye neempawu zayo zombane. Ixabiso layo eliphantsi kunye nokulula kokwenziwa kwemveliso kwenza kube yinto efanelekileyo kwizicelo ezininzi. Iitransistors zefilimu encinci zingenziwa ngayo. Ukushukuma kwayo okuphezulu kwenza kube ngumgqatswa olungileyo wezicelo ezinjalo.

Iimakroskopu ze-elektroni zothumelo lwe-high-resolution zisetyenziselwe ukufunda ubume beathom ye-MoS2. Umzobo we-2d ubonisa ukuba ukulungelelaniswa kwe-hexagonal kwii-athomu ze-Mo kwi-M-MoS2 kubonisa ubukho bemimandla ye-crystal enye ye-crystal ngaphakathi kwe-nanosheet nganye. Imigama yayo molybdenum–Mo ngokulandelelana yi-5.5+0.3 A kunye ne-2.8+0.3 A.

I-XPS spectroscopy ye-MoS2 ityhila i-molybdenum disulfide nanosheets ezinobunzima beenanometers ezimbalwa. I-X-reyi ye-energy dispersive spectroscopy ibonise ukuba umlinganiselo we-atom we-Mo ukuya ku-S yi-2.05. Nangona kunjalo, ngaphandle kwe-morphology efanayo, ezi khompawundi zimbini zibonisa umahluko obonakalayo kwiimpawu zazo zeRaman.

Iikhompawundi zeMolybdenum disulfide ziqhele ukusetyenziswa kwizithambisi zegiya zokwenziwa. Zingasetyenziswa kwizicelo zobushushu obuphezulu. Banokuthi bachaphazeleke ngakumbi ukuba bahlukane ne-oyile yesiseko. Ke ngoko, esona sisombululo silungileyo kwiingxaki zokuthambisa izixhobo sisithambiso esidityanisiweyo. Abavelisi banokudibanisa izongezo ezahlukeneyo ukwenza isithambiso esidityanisiweyo esinomthwalo ophezulu wokuthwala kunye nokusebenza okuphezulu kobushushu.

Ulwakhiwo lwe-MoS2 lwahluke kakhulu kwaye luqulathe iiathom ezinomaleko ohlukeneyo. Ezi maleko zinokuba yintsimbi, i-semiconducting, okanye i-superconducting. I-MoS2 inokubakho ngokobukhulu obahlukeneyo kunye neemilo. Kukho iintlobo ezintathu zezakhiwo ze-MoS2 ezikhoyo: i-hexagonal sphere (i-original sphere), i-hexagonal prismatic (i-hexagonal sphere), kunye ne-hexagonal prismatic (i-prismatic ene-hexagonal).
