Tungsten Sulfide (WS2): Magwiridwe antchito ndi kagwiritsidwe ntchito

WS2, yomwe imadziwikanso kuti tungsten sulfide ndi imvi, hexagonal system, semiconductor ndi diamagnetic. Ili ndi coefficient yotsika kwambiri ya kukangana (0.03), kukana kuthamanga kwambiri komanso kukana okosijeni (kuwola kumayamba pa 450 ℃ mumlengalenga, Ndi yoyenera kutentha kwambiri, kuthamanga kwambiri, vacuum yambiri, katundu wambiri, liwiro lalikulu, kuwala kwambiri, dzimbiri lamphamvu, kutentha kochepa kwambiri komanso zinthu zina zovuta.

WS2 / tungsten sulfides / tungsten disulfides / tungsten (IV)Sulfide ndi chinthu chomwe chakhala chikudziwika kwambiri pakati pa asayansi chifukwa cha makhalidwe ake apadera komanso momwe angagwiritsire ntchito. M'nkhaniyi, tifufuza zomwe WS2 ili, makhalidwe ake, ndi momwe ingagwiritsidwire ntchito m'magawo osiyanasiyana.

WS2ndi chinthu chopangidwa ndi maatomu a tungsten ndi sulfure, chokhala ndi formula ya mankhwala ya W(S2). Ndi cha m'banja la transition metal dichalcogenides (TMDs), zomwe ndi zinthu zokhala ndi zigawo zofanana ndi graphene. WS2 ili ndi kapangidwe ka zigawo komwe kali ndi maatomu a tungsten omwe ali pakati pa zigawo za maatomu a sulfure. WS2 imagwiritsa ntchito kapangidwe ka zigawo kogwirizana ndiMoS2(Molybdenum Disulfide), yokhala ndi maatomu a W omwe ali mu gawo la trigonal prismatic coordinate sphere, Kapangidwe kake ka magawo kamapatsa WS2 mawonekedwe ake apadera ndipo kamawapangitsa kukhala chinthu chosangalatsa pa kafukufuku wasayansi ndi ntchito zaukadaulo.

Chimodzi mwa zinthu zodziwika bwino zaWS2ndi mafuta ake opaka. WS2 ili ndi mafuta ochepa okangana, zomwe zimapangitsa kuti ikhale mafuta abwino kwambiri ogwiritsidwa ntchito m'njira zosiyanasiyana. Yagwiritsidwa ntchito ngati mafuta olimba m'malo otentha kwambiri komanso opanikizika kwambiri, monga m'mafakitale opanga ndege ndi magalimoto. Kapangidwe kake ka WS2 kamathandiza kuti isunthike mosavuta, kuchepetsa kukangana ndi kuwonongeka pakati pa malo.

Kuwonjezera pa mafuta ake odzola,WS2imasonyezanso khalidwe la semiconducting. Izi zikutanthauza kuti ingagwiritsidwe ntchito mu zipangizo zamagetsi ndi ntchito za optoelectronic. WS2 yawonetsa kuthekera kogwiritsidwa ntchito mu transistors, photodetectors, ndi maselo a dzuwa chifukwa cha mphamvu zake zapadera zamagetsi. Kutha kwake kuyamwa bwino ndi kutulutsa kuwala kumapangitsa kuti ikhale chinthu chabwino kwambiri pa zipangizo zamakono za optoelectronic za m'badwo wotsatira.

Komanso,WS2yaphunziridwa kuti ingathe kugwiritsidwa ntchito pokonza mphamvu ndi kusunga mphamvu. Malo ake okwera komanso ntchito yake yokonza mphamvu zimapangitsa kuti ikhale yabwino kwambiri yogwiritsidwa ntchito mu maselo amafuta, kusintha kwa hydrogen, ndi njira zina zokonzetsera mphamvu. Zipangizo zochokera ku WS2 zafufuzidwanso kuti zingathandize bwanji mu zipangizo zosungira mphamvu, monga mabatire ndi ma supercapacitor, chifukwa cha mphamvu zake zoyendetsera mphamvu komanso mphamvu zamagetsi.

Makhalidwe apadera aWS2zakopanso chidwi m'munda wa nanotechnology. Ma nanoparticles a WS2 ndi ma nanosheet apangidwa ndi kuphunziridwa chifukwa cha kuthekera kwawo mu ntchito zosiyanasiyana za nanotechnology, monga nanoelectronics, nanophotonics, ndi nanomedicine. Kutha kusintha ndikuwongolera mawonekedwe a WS2 pa nanoscale kumatsegula mwayi watsopano wopanga zinthu zamakono zamakono ndi ma nanodevices.

Powombetsa mkota,WS2 (tungsten sulfides)ali ndi ntchito zotsatirazi:

1. WS2 imagwiritsidwa ntchito makamaka pa zinthu zoyambitsa mafuta;

2. WS2 ndi chothandizira chatsopano chogwira ntchito bwino kwambiri;

3. WS2 ingagwiritsidwe ntchito ngati mafuta olimba, mafuta opaka filimu youma, zinthu zophatikizana zomwe zimadzipaka zokha;

4. WS2 imapanga zowonjezera mafuta ofunikira kwambiri;

5. WS2 ingagwiritsidwe ntchito ngati maselo amafuta a anode, anode ya batri ya organic electrolyte, okosijeni wa sulfure dioxide mu asidi wamphamvu mu anode ndi sensor ya anode;

6. WS2 imagwiritsidwa ntchito popanga zinthu zopangidwa ndi nano-ceramic;

7. WS2 ndi chinthu chabwino cha semiconductor.

Pomaliza,WS2, kapena tungsten sulfide, ndi chinthu chokhala ndi zinthu zosiyanasiyana zapadera komanso ntchito zake zomwe zingatheke. Zinthu zake zopaka mafuta, kachitidwe kake koyendetsa mafuta m'thupi, ntchito yake yothandiza anthu, komanso kuthekera kwake mu nanotechnology zimapangitsa kuti chikhale chinthu chosinthasintha chokhala ndi chiyembekezo chabwino m'magawo osiyanasiyana. Pamene kafukufuku wa WS2 akupitilizabe kupita patsogolo, ndizotheka kuti tidzawona chitukuko china ndi kugwiritsa ntchito chinthu chosangalatsachi mtsogolomu.
