E fana ka mehloli ea mocheso e shebaneng haholo bakeng sa ho tjheseletsa ka nepo, tlhahiso ea lintho tse tlatsetsang, le kalafo ea bokaholimo liindastering tsa lifofane le tsa likoloi.

Liaparo le Lifilimi tse Nyenyane:

E sebelisoa e le lipehelo tse sireletsang holim'a mahare a turbine, li-nozzle tsa rokete, le likarolo tsa reactor ea nyutlelie ho hanela mocheso o feteletseng le oxidation.

Single-Crystal LaB₆:

E sebetsa e le thepa ea cathode ea boleng bo holimo ho li-accelerator tsa likaroloana, li-synchrotrons, le litsamaiso tsa ho kenya li-ion.

3. Lisebelisoa tsa Tlhahlobo

Maemo a Phapang ea X-Ray (XRD):

E sebetsa e le thepa e netefalitsoeng ea boholo/khatello ho lekanya katoloso ea lisebelisoa tlhahlobong ea XRD, ho netefatsa ho nepahala lithutong tsa kristale.

Liphaephe tsa X-Ray:

E ntlafatsa khanya le bokgoni ba ho bona mehloding ya X-ray ya bongaka le ya diindasteri.

4. Theknoloji e Hlahang le e sa Feleng

Khomphutha le Patlisiso ea Quantum:

E fuputsitsoe bakeng sa tšebeliso ho li-emitter tsa quantum le lisebelisoa tsa spintronic ka lebaka la ho hasana ha eona ka tlase ha li-elektrone le ho tsamaea ha eona ka bongata.

Liphanele tsa Pontšo ea Plasma (PDPs):

E ntlafatsa bokgoni le nako ya bophelo dipontshong tse nang le tlhaloso e phahameng.

Ho Hlahloba Sebaka:

E sebelisoa ho li-thruster tsa ion le li-sensor tsa sepakapaka bakeng sa mesebetsi ea sepakapaka se tebileng.

5. Litšebeliso tsa Liindasteri le Tikoloho

Li-sensor tsa Mocheso o Phahameng:

E sebetsa ka har'a li-thermocouple le li-probe tsa mocheso bakeng sa lits'ebetso tsa metallurgical le tlhokomelo ea tšepe e qhibilihisitsoeng.

Lisebelisoa tsa Superconducting:

Ke hlahlobile metsoako e meholo bakeng sa polokelo ea matla le litsamaiso tsa ho phahamisa matla a makenete.

Melemo ea Bohlokoa ea LaB₆

Ho Tsitsisa Mocheso o Phahameng ka ho Fetisisa: E boloka tshebetso maemong a feteletseng (ho fihlela ho 1,800°C ka vacuum).

Ho se Sebete ha Lik'hemik'hale: E hanela ho bola ho bakoang ke li-acid, li-alkali le likhase tse arabelang.

Nako e Telele: E sebetsa ho feta di-cathode tsa tungsten ka makgetlo a 10–20 nakong ya tshebetso.

Melemo e Ikhethang ea Indasteri

Lifofane le Tšireletso: Litsamaiso tse tšepahalang tsa radar, puisano ea sathelaete, le liphahlo tsa tšireletso ea mocheso.

Li-semiconductor: E nolofalletsa lithography ea moloko o latelang bakeng sa tlhahiso ea li-chip tsa sub-5nm.

Lipatlisiso le Tlhokomelo ea Bophelo: Litšoantšo tse nang le qeto e phahameng ho TEMs le tlhahlobo e tsoetseng pele ea X-ray.

Lanthanum Hexaboride ke lejwe la motheo la diindasteri tsa theknoloji e hodimo tsa sejwalejwale, e kgannang boiqapelo ho nanotechnology, eneji, le saense ya quantum. Bokgoni ba yona ba ho ntsha dielektrone tse sa bapisweng le letho le matla di tiisa karolo ya yona e le thepa ya bohlokwa bakeng sa mahlale a hajwale le a moloko o latelang.

Hlokomela: Li-nanoparticle tsa LaB₆ li sebelisoa ka ho eketsehileng lipontšong tsa tlhahiso ea mobu (FEDs) le nanoelectronics, e leng se totobatsang ho ikamahanya ha eona le litlhoko tsa theknoloji tse ntseng li fetoha.
