(Waa maxay Dufanka Molybdenum Disulfide?)

Molybdenum disulfide waa ka samaysan ka samaysan molybdenite macdanta ah. Sababtoo ah tayada saliidda, xaruntan waxaa badanaa loo isticmaalaa saliidaha. Waxay ku samaysaa filim khafiif ah oogada birta ah, waxayna la falgashaa cadaadis si ay u bixiso saliid.

Molybdenum disulfide waxaa loo isticmaalaa saliidaha si loo hagaajiyo dufanka qaybaha birta loogana ilaaliyo xirashada. Iskudhisku wuxuu sameeyaa dahaadh dusha sare ah oo ku xidhan birta. Si kastaba ha ahaatee, wax ku oolnimada wax-ku-darku waa xaddidan tahay haddii ay ku sii jirto hakad, taas oo ah sababta ay tahay in ay la socoto saliidda. Isku dhafka aan ku habboonayn saliidda ayaa xannibi kara marinka saliidda oo shaandheyn kara.

Molybdenum disulfide waxay leedahay awood loo isticmaalo in lagu abuuro transistors leh hal atamka. Xaruntan ayaa awood u leh in lagu dhex daro aaladaha elektiroonigga ah sababtoo ah sifooyinka korantada ee aad u fiican. Weli waa walxo cusub. Markaa, inta badan shaqada xaruntan waxay ahayd tijaabo-iyo-qallad. Laakiin kooxdani waxay awood u yeelatay inay isticmaasho barnaamijka jilitaanka si ay u qaabeeyaan wareegga leh molybdenum disulfide si xog badan leh. Waxay la jaanqaadaysaa xaaladaha ugu xun ee suurtogalka ah, ka dibna waxay doorataa naqshadda ay u badan tahay in lagu guuleysto. Natiijooyinka imtixaannada ayaa markaa dib loogu celinayaa barnaamijka.

Molybdenum disulfide waxaa loo isticmaalaa dufanka loogu talagalay codsiyada waajibaadka culus. Waa saliid aad u fiican oo loogu talagalay birta. Xaruntan waxaa lagu sameeyay saabuun lithium ah si ay uga ilaaliso waxyeelada biyaha. Waxay ka hortagtaa dufanka in laga dhaqo biraha iyo geerka, ilaalinta iyaga. Dhumucyada saabuunta lithium waxay leeyihiin sifooyin isku dhejis ah oo aad u fiican, taas oo u oggolaanaysa saliidda in ay sii jirto muddo dheer.

Daraasado badan ayaa isku dayay inay sharaxaan habka isku dhaca gudaha molybdenum diulfide. Waa muhiim in la fahmo xidhiidhka ka dhexeeya shaqada iyo qaab-dhismeedka. Waxaa jira saddex dugsi oo waaweyn oo fikirka ku saabsan molybdenum diulfide. Dabeecadda garaafka ayaa saldhig u ah laba ka mid ah saddexda dugsi ee fikirka, halka dugsiga saddexaad uu ku saleeyo gunaanadkiisa habdhaqanka molybdenum.

MoO&, in kasta oo khilaafkiisu yar yahay si fudud ayaa loo jeexjeexi karaa iyadoo la isticmaalayo walxo xoqan. Heerka kala-goynta ayaa ka sarreeya qaybaha yaryar. Natiijadan waxaa sabab u ah joogitaanka molecules adsorbed on dusheeda. MoO& waxay la falgashaa sulfur dioxide si ay u samayso MoOz, iyo MoOa. Kuwani si fudud ayaa looga heli karaa dusha walxaha.

Molybdenum disulfide (MoS2) waa nooc cusub oo agab ah. Waxay ka kooban tahay biraha kala-guurka ee ku xidhan kooxda 16. Qaab dhismeedkiisu wuxuu la mid yahay graphite. Ronald E. Bell iyo Robert E. Herfert ayaa abuuray qaab cusub oo rhombohedral crystalline ah oo ah MoS2. Maaddada la helay waxay leedahay sifooyin la mid ah graphite.

Oxidation of molybdenum disulfide waxay abuurtaa molybdenum oxides iyo sufur elemental. Iskudhisyadani waa alaabooyinka ugu muhiimsan ee habka oksaydhka molybdenum.
