Kuyini i-silane?
I-Silane iyinhlanganisela ye-silicon ne-hydrogen, futhi yigama elijwayelekile lochungechunge lwama-compound. I-Silane ihlanganisa kakhulu i-monosilane (SiH4), i-disilane (Si2H6) kanye namanye ama-compound e-silicon hydrogen asezingeni eliphezulu, ngefomula ejwayelekile i-SinH2n+2. Kodwa-ke, ekukhiqizweni kwangempela, ngokuvamile sibhekisela kuma-monos...Funda kabanzi -
Igesi ejwayelekile: itshe lesisekelo lesayensi kanye nemboni
Ezweni elikhulu locwaningo lwesayensi kanye nokukhiqizwa kwezimboni, igesi ejwayelekile ifana neqhawe elithule ngemuva kwezigcawu, idlala indima ebalulekile. Ayigcini nje ngokuba nezinhlelo zokusebenza eziningi, kodwa futhi ikhombisa ithemba elithembisayo embonini. Igesi ejwayelekile iyinhlanganisela yegesi enomcabango owaziwa kahle...Funda kabanzi -
Ngaphambilini yayisetshenziselwa ukuqhumisa amabhaluni, i-helium manje isibe ngenye yezinsiza ezintuleka kakhulu emhlabeni. Iyini ukusetshenziswa kwe-helium?
I-Helium ingenye yamagesi ambalwa alula kunomoya. Okubaluleke kakhulu, izinzile impela, ayinambala, ayinaphunga futhi ayinangozi, ngakho-ke kuyisinqumo esihle kakhulu ukuyisebenzisa ukuqhuma amabhaluni azintantayo. Manje i-helium ivame ukubizwa ngokuthi “igesi elingavamile” noma “igesi legolide”. I-Helium ...Funda kabanzi -
Ikusasa Lokubuyiselwa Kwe-Helium: Izinto Ezintsha Nezinselele
I-Helium iyisisetshenziswa esibalulekile ezimbonini ezahlukahlukene futhi ibhekene nokuntuleka okungenzeka ngenxa yokutholakala okulinganiselwe kanye nesidingo esikhulu. Ukubaluleka Kokubuyiselwa Kwe-Helium I-Helium ibalulekile ekusetshenzisweni kusukela ekuthathweni kwezithombe zezokwelapha kanye nocwaningo lwesayensi kuya ekukhiqizeni nasekuhloleni isikhala....Funda kabanzi -
Ayini amagesi aqukethe i-fluorine? Yimaphi amagesi akhethekile avamile aqukethe i-fluorine? Lesi sihloko sizokukhombisa
Amagesi akhethekile kagesi ayigatsha elibalulekile lamagesi akhethekile. Angena cishe kuzo zonke izixhumanisi zokukhiqizwa kwe-semiconductor futhi ayizinto zokusetshenziswa ezibalulekile ekukhiqizweni kwezimboni ze-elekthronikhi ezifana namasekethe ahlanganisiwe amakhulu kakhulu, amadivayisi okubonisa amaphaneli ayisicaba, kanye namaseli elanga...Funda kabanzi -
Iyini i-Green Ammonia?
Emkhankasweni wekhulu leminyaka wokuphakama kwekhabhoni kanye nokungathathi hlangothi kwekhabhoni, amazwe emhlabeni wonke afuna ngenkuthalo isizukulwane esilandelayo sobuchwepheshe bamandla, futhi i-ammonia eluhlaza iba yinto ebalulekile emhlabeni wonke muva nje. Uma kuqhathaniswa ne-hydrogen, i-ammonia iyanda kusukela kwendabuko kakhulu...Funda kabanzi -
