Uburyo bushya butanga microparticles ya homogeneous polystyrene muburyo butatanye

 

 Umusaruro wa microparticles ya homogeneous polystirene mukwirakwiza gutekanye

Gukwirakwiza ibice bya polymer mugice cyamazi (latexes) bifite akamaro kanini muburyo bwa tekinoroji, amashusho yubuvuzi, na biologiya selile.Itsinda ry’abashakashatsi bo mu Bufaransa ubu ryateguye uburyo, nk'uko byatangajwe mu kinyamakuruAngewandte Chemie Edition Edition, kubyara polystirene ihamye itatanye hamwe nini nini kandi itigeze ibaho.Ingano ntoya ni ngombwa muri tekinoroji yateye imbere, ariko mbere byari bigoye kubyara amafoto.

 

Polystirene, ikoreshwa kenshi mugukora ifuro yagutse, nayo ikwiranye no gukora latexes, aho uduce duto twa microscopique duto duto twa polystirene duhagarikwa.Zikoreshwa mugukora ibishishwa hamwe n amarangi kandi no mubikorwa bya kalibrasi muri microscopi kimwe no murin'ubushakashatsi ku binyabuzima.Mubisanzwe bikozwe nubushyuhe cyangwa redox-iterwamu gisubizo.

Kugirango ubone igenzura ryo hanze kubikorwa, amakipe Muriel Lansalot, Emmanuel Lacôte, na Elodie Bourgeat-Lami muri Université Lyon 1, Ubufaransa, na bagenzi be, bahinduye inzira itwarwa numucyo.Lacôte agira ati: "Polimerisiyumu itwarwa n'umucyo itanga igenzura ry'agateganyo, kubera ko polymerisiyasi igenda gusa imbere y'umucyo, mu gihe uburyo bw'ubushyuhe bushobora gutangira ariko ntibuhagarare igihe butangiye."

Nubwo UV- cyangwa ubururu-urumuri rushingiye kuri Photopolymerisation yashizweho, bifite aho bigarukira.Imirasire ngufi-imirasire itatanye iyo iiba hafi yimirasire yumurambararo, bigatuma latexes ifite ubunini bunini burenze uburebure bwumurongo winjira bigoye kubyara.Byongeye kandi, urumuri rwa UV rufite ingufu nyinshi, tutibagiwe n’akaga ku bantu bakorana nayo.

Abashakashatsi rero bakoze sisitemu yo gutangiza imiti itunganijwe neza isubiza urumuri rusanzwe rwa LED murwego rugaragara.Ubu buryo bwa polymerisation, bushingiye ku irangi rya acridine, stabilisateur, hamwe n’ikigo cya borane, ni cyo cyambere cyatsinze “igisenge cya nanometero 300,” ingano y’ubunini bwa UV hamwe n’ubururu-butwarwa na polymerisiyumu mu buryo butatanye.Nkigisubizo, kunshuro yambere, itsinda ryashoboye gukoresha urumuri kubyara polystirene latexes ifite ubunini burenze micrometero imwe kandi ifite diameter imwe.

Itsinda ryerekana ibyifuzo birenze.Lacôte agira ati: "Sisitemu ishobora gukoreshwa ahantu hose hakoreshwa latxes, nka firime, ibifuniko, inkunga yo gusuzuma, n'ibindi."Mubyongeyeho, ibice bya polymer bishobora guhinduka hamwe, magnetiki cluster, cyangwa nibindi bikorwa byingirakamaro mugusuzuma no kwerekana amashusho.Iri tsinda rivuga ko ingano nini yingero zingana zingana na nano na mikoro ntoya byagerwaho “muguhuza imiterere yambere.
