Kugwiritsa Ntchito Machubu Oyesera mu Laboratory Machubu oyesera ndi chimodzi mwa zinthu zodziwika bwino za magalasi zomwe zimapezeka m'ma laboratories, kusukulu komanso kusukulu, komanso m'ma laboratories ofufuza ndi mafakitale. Mawonekedwe awo ndi osavuta: silinda yayitali yokhala ndi maziko ozungulira komanso pamwamba potseguka. Ngakhale kuti amaoneka osafunika kwenikweni, machubu oyesera amachita gawo lofunika kwambiri mu ntchito zosiyanasiyana za labu ndi kusanthula chifukwa amalola... Werengani zambiri

Ubwino ndi Kuopsa kwa Mankhwala Ophera Tizilombo toyambitsa matenda Mankhwala ophera tizilombo ndi zinthu kapena zosakaniza za mankhwala omwe amagwiritsidwa ntchito poletsa zamoyo zowononga zomera (OPT) monga tizilombo, bowa, udzu, makoswe, ndi tizilombo tina. Mu ulimi wamakono, mankhwala ophera tizilombo nthawi zambiri amaonedwa kuti ndi "opulumutsa moyo" chifukwa amatha kupewa kuwonongeka kwa mbewu mwachangu. Komabe, kugwiritsa ntchito mankhwala ophera tizilombo kumabweretsanso zotsatirapo... Werengani zambiri

Machitidwe a Mankhwala mu Moyo wa Tsiku ndi Tsiku Machitidwe a mankhwala ndi njira yomwe chinthu chimasintha kukhala chinthu chatsopano chokhala ndi makhalidwe osiyanasiyana. Kusintha kumeneku kumachitika chifukwa maatomu omwe amapanga chinthucho amasinthidwa: ma bond akale a mankhwala amasweka, ndipo atsopano amapangidwa. Ngakhale kuti mawu akuti "chemical reaction" amamveka ngati asayansi, timawakumana nawo tsiku lililonse—kuyambira kuphika chakudya cham'mawa mpaka kuyeretsa nyumba mpaka... Werengani zambiri

Zotsatira za pH pa Ntchito ya Enzyme Ma Enzyme ndi mamolekyu achilengedwe—nthawi zambiri mapuloteni—omwe amagwira ntchito ngati ma catalyst mu zochita za mankhwala mkati mwa zamoyo. Popanda ma enzyme, zochita zambiri za kagayidwe kachakudya zimayenda pang'onopang'ono kwambiri kotero kuti sizingathe kupirira moyo. Komabe, kuthekera kwa ma enzyme kufulumizitsa zochita sikugwira ntchito "mosadalira momwe zinthu zilili". Ntchito ya enzyme imakhudzidwa kwambiri ndi zinthu zachilengedwe, ndipo… Werengani zambiri

Udindo wa Chemistry mu Ulimi Ulimi wakhala gawo limodzi mwa magawo ofunikira kwambiri pa moyo wa anthu kuyambira nthawi zakale. Kutha kwa anthu kulima ndi kukolola mbewu ndiye maziko a chitukuko ndi chitukuko cha anthu amakono. Poyang'anizana ndi mavuto a ulimi wamakono, monga kukula kwa anthu padziko lonse lapansi, kusintha kwa nyengo, ndi kuchepa kwa zinthu, chemistry imagwira ntchito yofunika kwambiri pothandizira...

Momwe Mungawerengere Kuchuluka kwa Madzi mu Chitsanzo Kuchuluka kwa chinyezi ndi chinthu chofunikira kwambiri kumvetsetsa m'mafakitale osiyanasiyana, kuyambira ulimi ndi chakudya mpaka mankhwala ndi zomangamanga. Kuchuluka kwa chinyezi kumakhudza mwachindunji ubwino, nthawi yosungiramo zinthu, komanso kugwiritsidwa ntchito kwa chinthu kapena zinthu. Chifukwa chake, kudziwa ndi kuwongolera kuchuluka kwa chinyezi ndikofunikira. Nkhaniyi… Werengani zambiri

Kodi Magulu Ogwira Ntchito mu Organic Chemistry Ndi Chiyani? Organic chemistry ndi nthambi ya chemistry yomwe imaphunzira kapangidwe, makhalidwe, kapangidwe, zochita, ndi kapangidwe ka mankhwala a organic okhala ndi kaboni. Mu organic chemistry, lingaliro la magulu ogwira ntchito ndilofunika kwambiri kuti timvetsetse kusiyana kwa makhalidwe ndi momwe zinthu zosiyanasiyana za organic zimagwirira ntchito. Gulu logwira ntchito ndi gulu la ma atomu mkati mwa molekyulu yomwe imayang'anira… Werengani zambiri

Machitidwe a Mankhwala Omwe Amachitika M'mabatire Mabatire akhala chimodzi mwazinthu zatsopano kwambiri m'mbiri ya anthu, zogwiritsa ntchito zida zoyambira mawotchi apamanja mpaka magalimoto amagetsi.
