2. Shatterproof iav tau tsim los ntawm kev sib tsoo. Fabkis kws tshuaj Edouard Benedictus inadvertently invented shatterproof iav thaum nws poob ib khob iav coated nyob rau hauv cellulose nitrate cellulose nitrate A filter binding assay yog ib txoj hauv kev yooj yim kom sai sai kawm ntau yam qauv. Nws ntsuas affinities ntawm ob molecules (feem ntau protein thiab DNA) siv lub lim. Lub lim yog tsim los ntawm cov ntawv nitrocellulose, uas yog qhov tsis zoo. https://en.wikipedia.org › wiki › Filter_binding_assay

Thaum twg yog tawg pov thawj iav tsim?
Kev Tshawb Nrhiav Tsis Pom Zoo ntawm Shatterproof Glass
Lub iav kev nyab xeeb tsheb tuaj yeem taug qab nws keeb kwm rov qab mus rau 1903, thaum tus kws tshuaj Fab Kis hu ua Edouard Benedictus tau ua haujlwm nrog cov iav iav hauv nws lab. Benedictus tau muab cov txheej pob tshab rau hauv ib lub khob uas nws siv rau nws qhov kev sim.
Yuav pom cov iav tawg tau li cas?
Edouard Benedictus ua qhov kev tshawb pom tsis tseeb hauv nws lub chaw kuaj mob. Muaj ib hnub, xyoo 1903 nws poob ib lub khob xa lub khob rau hauv pem tebNws tawg - tab sis nws cov khoom tuav ua ke. Cellulose nitrate, cov kua yas ntshiab uas tshuav nyob rau hauv lub beaker, tau qhuav thiab ua kom lub khob tsis txhob tawg mus rau hauv shards.
Leej twg tsim cov iav tiv thaiv?
Nyob rau xyoo 1909 thawj qhov kev vam meej patent rau iav kev nyab xeeb tau raug coj tawm hauv Fabkis los ntawm tus kws kos duab thiab kws tshuaj, Édouard Bénédictus, leej twg siv daim ntawv ntawm celluloid bonded ntawm ob daim iav..
Leej twg nrhiav tau tempered iav?
Francois Barthelemy Alfred Royer de la Bastie (1830–1901) ntawm Paris, Fabkis tau txais txiaj ntsig nrog thawj zaug tsim cov iav tempering los ntawm quenching yuav luag molten iav hauv da dej kub. Cov roj lossis roj hauv xyoo 1874, txoj kev patented hauv tebchaws Askiv thaum Lub Yim Hli 12, 1874, patent naj npawb 2783.
