khofi wothira thovu amachotsa mtovu m'madzi oipitsidwa

Kaya mumaikonda nthawi yomweyo kapena yophikidwa kumene, palibe chinsinsi kuti khofi ndi chimodzi mwazakumwa zamasiku ano zomwe zimadyedwa kwambiri. Ngati mumatsamira kwambiri kapu yatsopano ya khofi, mutha kutaya zomwe mwawononga kapena kuzibwezeretsanso kuti mugwiritse ntchito dimba kapena kompositi - koma tsopano, gulu la ofufuza motsogozedwa ndi Despina Fragouli apeza njira yopindulira malo otsalawo! Pophatikiza thovu la bioelastomeric ndikugwiritsa ntchito khofi mu mawonekedwe a ufa, adapeza kuti amatha kuchotsa 99 peresenti ya lead ndi mercury mu Madzi osatwanima. Ndikuganiza kuti ndibwino kudziwa kuti kapu ya khofi ikhoza kuchita zambiri kuposa kukuthandizani kuti muzipita kapena kukuthandizani kuti muzitha kugona usiku wonse. Mwanjira ina, khofi sikuti imangoyamba tsiku lanu bwino - itha kukhalanso njira ina yoyeretsera madzi.

The Italy Institute of Technology, motsogozedwa ndi Fragouli, adanenedwa kuti, "Kuphatikizika kwa ufa wa khofi womwe wagwiritsidwa ntchito muzitsulo zolimba, popanda kusokoneza magwiridwe ake, kumathandizira kasamalidwe ndikulola kuti zoipitsa zilowe mu thovu zomwe zimapangitsa kuti ziwonongeke." Izi zikutanthauza kuti kuphatikiza komwe adapanga kuti achotse zitsulo zolemera m'madzi oipitsidwa kumatha kutayidwa bwino, ngati sikusinthidwa. Izi ndi zofunika chifukwa zingatanthauze chinthu chimodzi chocheperako chomwe tingadye mosadziwa; Komanso, kukhala ndi madzi aukhondo popanda kugula choyeretsera madzi kungakhale kwabwino. Ndizodziwikiratu kuti Fragouli adadzipereka kuti apatse anthu padziko lapansi mwayi wokonda zachilengedwe kuti asunge madzi akumwa motetezeka komanso mosangalatsa momwe angathere.

Despina: Mbiri Yachidule

Tisanalowe mopitilira muyeso wochititsa chidwiwa, tiyeni tiphunzire pang'ono za Despina Fragouli - mtsogoleri wa polojekitiyi. Atamaliza maphunziro ake ndi BS in Physics ku University of Crete ku Greece, adapereka a nkhani yolembedwa pa "Kufufuza za zochitika za photochemical panthawi yochotsa ma polima ndi UV laser [s]", momwe iye adagwirizana ndi Foundation of Research and Technology - Institute of Electronic Structure and Laser (FORTH-IESL). Mu 2002, adamulandira Mphunzitsi wa Sayansi mu Applied Molecular Spectroscopy, Dipatimenti ya Chemistry, University of Crete; Kuphatikiza apo, adapereka lingaliro la "Kukula kwa Multispectral Imaging System yojambulitsa mu vivo ndikuwunika ma kinetics a kuyanjana kwa ma acid ofooka ndi minofu: Kugwiritsa ntchito pa matenda a khansa ndi kupotoza kwa khansa isanayambe", kugwirizananso ndi FORTH-IESL. . Kuti mudziwe zambiri zaposachedwa, chonde Dinani apa.

Malo a Khofi: Kusinthasintha pakubwezeretsanso

American Chemical Society idapanga a phunziro mu 2015, zomwe zidawonetsa kuti malo omwe amagwiritsidwa ntchito khofi amatha kukulitsa kachulukidwe kazakudya muzakudya zina. Izi ndizodabwitsa chifukwa zikutanthauza kuti, pambali kukonza madzi, zinthu zina zake zingakhale zothandiza kwa ife. Zinthu zomwe zimagwiritsidwa ntchito pazakudya zimatchedwa phenols kapena antioxidants. Sikuti amangowonjezera kuchuluka kwa zakudya, koma pali kale kuchuluka kwawo komwe kumagwiritsidwa ntchito. Ndizodabwitsa kuwona mtundu waukadaulo womwe umachokera ku zakumwa zomwe zimadyedwa kwambiri padziko lonse lapansi. Kudziwa kuti zomwe mumamwa m'mawa uliwonse zimapindulitsa thanzi ladziko lapansi kuyenera kukhala kowonjezera mphamvu monga chakumwacho!

Mmodzi pang'ono owonjezera zosangalatsa mfundo anathera khofi chifukwa angagwiritsidwe ntchito ngati feteleza kwa dimba lako! Mazikowa amachepetsa acidity mwa kuwonjezera nayitrogeni ndi potaziyamu, ndipo amawonjezera magnesium kunthaka ndi zomera. M'mawu ena, imalimbitsa chitetezo cha mthupi cha mmera ndikuchotsa nkhono ndi ma slugs kutali. Onetsetsani kuti muwone kanema wachidule pansi pa tsamba ndi kuwonekera apa.

Kusavuta Kuchotsa Madzi

Bungwe la Italy Institute of Technology, lomwe limatsogozedwa ndi Despina Fragouli yemwe watchulidwa kale, adayesetsa kuchepetsa kuwononga madzi. Monga tafotokozera kale, ofufuzawo adalongosola momwe malo a khofi amagwiritsidwira ntchito amatha kukopa ndi kusonkhanitsa zowononga, kotero kuti zikhoza kuchotsedwa mopanda vuto komanso moyenera kuchokera mkati mwa chinthu.

Malinga ndi Nsikan Akpan, njira imeneyi yochepetsera madzi ndi zimene asayansi akhala akuyesetsa kuchita kale. Zoyeserera zakale zomwe adapanga pochotsa zitsulo zolemera m'madzi zidakhala "zosafunikira". Anaphwanya malowo kukhala ufa, kenaka anasakaniza ndi madzi oipitsidwa ndi mtovu. Akpan akuphatikiza kuyesa kulephera kuwononga madzi mwa kungonena kuti, "Mukufuna fyuluta ya fyuluta." Kwenikweni zigawo za osakaniza sizinali zolimba kuti zichotse zambiri zazitsulo.

Zomwe Fragouli ndi gulu lake adachita mosiyana ndikuti iwo kulowetsedwa ndi mankhwala malo ogwiritsidwa ntchito thovu elastic, moti 60 mpaka 70 peresenti ya kulemera kwake inali khofi. Apkan akupitiliza kufotokoza kuti ngati "adayamba ndi madzi okhala ndi magawo asanu ndi anayi pa miliyoni imodzi ya lead - Nthawi 360 ili pamwamba (kuti mumve zambiri za chiphunzitsochi) kuposa kuchuluka komwe kumapezeka pamavuto amadzi a Flint - thovulo limatha kuchotsa gawo limodzi mwa magawo atatu a kuipitsidwa kwa mphindi 30. ” Zikuwoneka kuti Apkan ali ndi malingaliro abwino kwambiri ogwiritsira ntchito lusoli, ndipo n'zosavuta kumvetsetsa chifukwa chake: zingathandize omwe akufufuza kuti awone ngati njira iyi yothetsera madzi ingagwiritsidwe ntchito pamlingo waukulu kwambiri. Komabe, kuchita bwino kwa lusoli pamlingo waukulu kuyenera kuganiziridwa ndi kutsimikiziridwa ndi Fragouli ndi gulu la Italy Institute of Technology asanafike oganiza bwino ngati Apkan.

Zikuyimirabe kuti Despina Fragouli ndi gulu lake adapanga njira yaukhondo komanso yolimba yosefera kukonzanso madzi. Kodi mungaganizire ubwino wotani umene zimenezi zingachitire mayiko amene sangakwanitse kupeza madzi aukhondo? Funso ndilakuti njira iyi ingagwiritsidwe ntchito pati komanso kuchuluka kwake komwe kungaloledwe kutero. Mwachiyembekezo izi zikukhala chizolowezi pakati pa asayansi ndi omwe amayang'anira zoperekera madzi mumzinda wawo; Kukhala ndi madzi aukhondo kungaoneke ngati chinthu chachilendo, koma kungakhale kosangalatsa kwa anthu ena.
