Sensor ya Gazi Igendanwa yo Gusuzuma Monoxide ya Karuboni mu Gihe Nyacyo

Mu nkuru iherutse gusohoka mu kinyamakuru Scientific Reports, abashakashatsi baganiriye ku iterambere rya sisitemu yo gupima gaze igendanwa kugira ngo imenye monoxide ya karubone mu buryo bwihuse. Iyi sisitemu nshya ihuza sensor zigezweho zishobora gukurikiranwa byoroshye binyuze kuri porogaramu ya terefone igendanwa. Ubu bushakashatsi bugamije gutanga igisubizo gito kandi cyiza cyo kugenzura ingano ya CO mu bidukikije bitandukanye.

Ubushakashatsi bwakozwe mbere bwagaragaje akamaro ko gupima ibikomoka kuri peteroli mu gutahura imyuka yangiza nka monoxyde de carbone. Guhuza ikoranabuhanga rigezweho, harimo na microcontrollers na porogaramu za telefoni zigendanwa, bishobora kunoza imikorere no kugera ku buryo ibikoresho bipima ibikomoka kuri peteroli bigerwaho. Gukoresha PN heterojunctions n'ibikoresho byihariye bya nanowire nka CuO/copper foam (CF) byarushijeho kunoza uburyo ibi bipima bikoresha peteroli bifatwa n'uburyo bitoranywa.

Iyi sensor yahujwe n'ibikoresho byo gupima ingufu n'ubudahangarwa kugira ngo ikurikirane impinduka mu budahangarwa iyo ihuye n'ingano zitandukanye za lisansi. Igikoresho cyose cyari gifunze mu cyumba cyo kugenzura kugira ngo gishushanye uburyo nyabwo bwo kumenya lisansi.

Kugira ngo harebwe imikorere rusange y'igikoresho gipima lisansi, hasuzumwe ingano zitandukanye za azote (N2), ogisijeni (O2), na gazi ya monoxide ya karuboni (CO). Ingano ya lisansi yari hagati ya ibice 10 kuri miliyoni kugeza ku bice 900 kuri miliyoni (ppm) kugira ngo harebwe imiterere y'ubuhanga n'uburyo icyuma gipima. Igihe cyo gusubiza n'igihe cyo gukira cyandikwa ku bushyuhe bwihariye n'ubushuhe kugira ngo hamenyekane imikorere yacyo mu bihe bitandukanye by'ibidukikije.

Mbere yo gukora igerageza ryo kumenya gazi, sisitemu yo kumenya gazi igomba kunyura mu buryo bwo gupima kugira ngo imenye neza kandi bwizewe. Umurongo wo gupima ukorwa binyuze mu gushyira sensor ku gipimo cya gazi kizwi kandi gihuza impinduka mu bushyuhe n'urwego rwa gazi. Uburyo sensor ikora bugenzurwa hakurikijwe amabwiriza yashyizweho yo kumenya gazi kugira ngo harebwe neza kandi ko ihamye mu kumenya gazi ya monoxide.

Dushobora gutanga ibikoresho bipima imyuka itandukanye, nk'uko bikurikira
