Ua hoʻomohala ʻo Prof. Moran Bercovici lāua ʻo Dr. Valeri Frumkin i ka ʻenehana haʻahaʻa no ka hana ʻana i nā lens optical, a hiki ke hana i nā aniani no nā ʻāina ulu he nui kahi i loaʻa ʻole ai nā makaʻala.I kēia manawa, ʻōlelo ʻo NASA hiki ke hoʻohana ʻia e hana i nā telescopes space
Ke holomua nei ka ʻepekema ma nā ʻanuʻu liʻiliʻi.Hoʻohui ʻia kahi ʻāpana ʻike liʻiliʻi i kēlā me kēia hoʻokolohua hou.He mea kakaikahi ka manaʻo maʻalahi i ʻike ʻia i loko o ka lolo o ke kanaka ʻepekema e alakaʻi i kahi holomua nui me ka ʻole o ka hoʻohana ʻana i kekahi ʻenehana.Akā ʻo kēia ka mea i loaʻa i ʻelua mau ʻenehana Israeli i hoʻomohala i kahi ala hou o ka hana ʻana i nā lens optical.
He maʻalahi ka ʻōnaehana, haʻahaʻa a pololei, a hiki ke loaʻa ka hopena nui a hiki i ka hapakolu o ka heluna kanaka o ka honua.Hiki ke hoʻololi i ke ʻano o ka noiʻi lewa.No ka hoʻolālā ʻana, pono nā mea noiʻi i kahi papa keʻokeʻo, kahi māka, kahi holoi a me kahi laki liʻiliʻi.
ʻO Polofesa Moran Bercovici lāua ʻo Kauka Valeri Frumkin mai ke Keʻena ʻEnekinia Mechanical o ka Technion-Israel Institute of Technology ma Haifa i loea i ka mīkini wai, ʻaʻole optics.Akā i hoʻokahi makahiki a me ka hapa i hala aku nei, ma ka World Laureate Forum ma Shanghai, ua noho ʻo Berkovic me David Ziberman, he mea hoʻokele waiwai o ka ʻIseraʻela.
He mea lanakila ʻo Zilberman i ka makana Wolf, a i kēia manawa ma ke Kulanui o Kaleponi, Berkeley, ua kamaʻilio ʻo ia e pili ana i kāna noiʻi ʻana i nā ʻāina ulu.Ua wehewehe ʻo Bercovici i kāna hoʻokolohua wai.A laila nīnau ʻo Ziberman i kahi nīnau maʻalahi: "Hiki iā ʻoe ke hoʻohana i kēia e hana i nā aniani?"
"Ke noʻonoʻo nei ʻoe i nā ʻāina e ulu nei, noʻonoʻo ʻoe i ka maʻi maʻi, ke kaua, ka pōloli," wahi a Berkovic."Akā, ua ʻōlelo ʻo Ziberman i kahi mea aʻu i ʻike ʻole ai - 2.5 biliona poʻe ma ka honua e pono i nā aniani akā ʻaʻole hiki ke loaʻa iā lākou.He helu kupaianaha kēia. "
Ua hoʻi ʻo Bercovici i ka home a ʻike i kahi hōʻike mai ka World Economic Forum i hōʻoia i kēia helu.ʻOiai he liʻiliʻi wale nō ke kumukūʻai no ka hana ʻana i nā makaaniani maʻalahi, ʻaʻole i hana ʻia a kūʻai ʻia paha nā aniani liʻiliʻi ma ka hapa nui o ka honua.
Nui ka hopena, mai nā kamaliʻi ʻaʻole hiki ke ʻike i ka papa ʻeleʻele ma ke kula a hiki i ka poʻe mākua e pohō loa ka ʻike a nalowale kā lākou hana.Ma waho aʻe o ka hoʻopōʻino ʻana i ka maikaʻi o ke ola o ka poʻe, ua manaʻo ʻia ke kumukūʻai o ka hoʻokele waiwai honua e like me US $3 trillion i kēlā me kēia makahiki.
Ma hope o ke kamaʻilio ʻana, ʻaʻole hiki iā Berkovic ke hiamoe i ka pō.I kona hōʻea ʻana i Technion, ua kūkākūkā ʻo ia i kēia pilikia me Frumkin, ʻo ia ka mea noiʻi postdoctoral ma kāna hale hana i kēlā manawa.
"Ua kiʻi mākou i kahi pana ma ka papa keʻokeʻo a nānā iā ia," i hoʻomanaʻo ai ʻo ia."Ua ʻike maoli mākou ʻaʻole hiki iā mākou ke hana i kēia ʻano me kā mākou ʻenehana hoʻokele wai, a makemake mākou e ʻike i ke kumu."
ʻO ke ʻano spherical ke kumu o ka optics no ka mea ua hana ʻia ka lens.Ma ke kumumanaʻo, ua ʻike ʻo Bercovici lāua ʻo Frumkin e hiki iā lāua ke hana i ka dome poepoe mai kahi polymer (he wai i paʻa) e hana i kahi lens.Akā, hiki i nā wai ke noho spherical wale nō i nā puke liʻiliʻi.Ke ʻoi aku ka nui, na ka umekaumaha e ʻoki iā lākou i loko o nā puddles.
"No laila ʻo ka mea e hana ai mākou e hoʻopau i ka gravity," wehewehe ʻo Bercovici.A ʻo ia ka mea a lāua me Frumkin i hana ai.Ma hope o ke aʻo ʻana i kā lākou papa keʻokeʻo, ua hele mai ʻo Frumkin me kahi manaʻo maʻalahi loa, akā ʻaʻole maopopo ke kumu i noʻonoʻo ʻole ai kekahi ma mua-inā hoʻokomo ʻia ka lens i loko o kahi keʻena wai, hiki ke hoʻopau ʻia ka hopena o ka umekaumaha.ʻO nā mea a pau āu e hana ai, ʻo ia ka hoʻopaʻa ʻana o ka wai i loko o ke keʻena (i kapa ʻia ʻo buoyant liquid) i like ka like me ka polymer kahi i hana ʻia ai ka lens, a laila e lana ka polymer.
ʻO kekahi mea nui ʻo ka hoʻohana ʻana i ʻelua mau wai immiscible, ʻo ia hoʻi ʻaʻole e hui pū kekahi me kekahi, e like me ka aila a me ka wai."ʻO ka hapa nui o nā polymers e like me nā aila, no laila ʻo kā mākou 'singular' buoyant wai ka wai," wahi a Bercovici.
Akā, no ka mea he haʻahaʻa ka wai ma mua o nā polymers, pono e hoʻonui iki ʻia kona ʻano i mea e lana ai ka polymer.No kēia hopena, ua hoʻohana nā mea noiʻi i nā mea liʻiliʻi liʻiliʻi-ka paʻakai, ke kō a me ka glycerin.Ua ʻōlelo ʻo Bercovici, ʻo ka mea hope loa o ke kaʻina hana he ʻano paʻa i loko o ka polymer i hoʻokomo ʻia i hiki ke hoʻomalu ʻia kona ʻano.
Ke hiki ka polymer i kona ʻano hope loa, hoʻōla ʻia me ka hoʻohana ʻana i ka radiation ultraviolet a lilo i lens paʻa.No ka hana ʻana i ke kiʻi, ua hoʻohana nā mea noiʻi i kahi paipu hoʻoheheʻe maʻalahi, ʻoki ʻia i loko o ke apo, a i ʻole kahi ipu petri i ʻoki ʻia mai lalo."Hiki i kēlā me kēia keiki ke hana iā lākou ma ka home, a ua hana wau me kaʻu mau kaikamahine i ka home," wahi a Bercovici."I loko o nā makahiki, ua hana mākou i nā mea he nui i loko o ka hale hana, ʻo kekahi o ia mau mea paʻakikī loa, akā ʻaʻohe kānalua ʻo kēia ka mea maʻalahi a maʻalahi loa a mākou i hana ai.ʻO ka mea nui paha. "
Ua hana ʻo Frumkin i kāna pana mua ma ka lā hoʻokahi āna i manaʻo ai i ka hopena."Ua hoʻouna mai ʻo ia iaʻu i kahi kiʻi ma WhatsApp," i hoʻomanaʻo ai ʻo Berkovic."I ka nānā hou ʻana, he lens liʻiliʻi a maikaʻi ʻole kēia, akā hauʻoli nui mākou."Ua hoʻomau ʻo Frumkin i ke aʻo ʻana i kēia mea hou.“E hōʻike ana ka hoohalike i ka wā e wehe ai ʻoe i ka ʻumekaumaha, ʻaʻole ia he mea nui inā hoʻokahi kenimika a i ʻole hoʻokahi kilomika ke kiʻi;ma muli o ka nui o nā mea, e loaʻa mau iā ʻoe ke ʻano like. "
Ua hoʻomau nā mea noiʻi ʻelua i ka hoʻokolohua me ka lua o ka hanauna huna mea huna, ka mop bākeke, a hoʻohana iā ia e hana i kahi lens me ke anawaena o 20 knm i kūpono no nā telescopes.Ke piʻi nui nei ke kumukūʻai o ka lens me ke anawaena, akā me kēia ʻano hana hou, me ka nānā ʻole i ka nui, ʻo nā mea āpau āu e makemake ai he polymer cheap, ka wai, ka paʻakai (a i ʻole ka glycerin), a me ka mold apo.
Hōʻike ka papa inoa mea hoʻohui i kahi loli nui i nā ʻano hana hana lens kuʻuna i noho ʻole ʻia no 300 mau makahiki.I ka pae mua o ke kaʻina hana maʻamau, ua hoʻoheheʻe ʻia ke aniani a i ʻole ka pā plastik.No ka laʻana, i ka wā e hana ai i nā lens makamaka, ma kahi o 80% o nā mea i pau.Ke hoʻohana nei i ke ʻano hana i hoʻolālā ʻia e Bercovici a me Frumkin, ma kahi o ka wili ʻana i nā mea paʻa, hoʻokomo ʻia ka wai i loko o ke kiʻi, i hiki ke hana ʻia ka lens i kahi kaʻina hana ʻole.ʻAʻole pono kēia ʻano i ka polishing, no ka mea, hiki i ka ʻili o ka ʻili o ka wai ke hōʻoia i kahi ʻili maikaʻi loa.
Ua kipa ʻo Haaretz i ka hale hana o Technion, kahi i hōʻike ai ka haumāna kauka ʻo Mor Elgarisi i ke kaʻina hana.Hoʻokomo ʻo ia i ka polymer i loko o ke apo i loko o kahi keʻena wai liʻiliʻi, hoʻomālamalama ʻia me ke kukui UV, a hāʻawi mai iaʻu i ʻelua mau mīkina lima lima ma hope o ʻelua mau minuke.Hoʻokomo pono wau i koʻu lima i loko o ka wai a huki i ka lens."ʻO ia, ua pau ka hana ʻana," i hoʻōho ai ʻo Berkovic.
Maʻalahi loa nā lens i ka hoʻopā ʻana.ʻAʻole kēia he manaʻo pilikino wale nō: ʻōlelo ʻo Bercovici ʻoiai me ka ʻole o ka poli ʻana, ʻoi aku ka liʻiliʻi o ka ʻili o ka lens me ka hoʻohana ʻana i ke ʻano polymer ma mua o hoʻokahi nanometer (hoʻokahi biliona o ka mika)."Hoʻokumu nā mana o ke ʻano i nā ʻano ʻokoʻa ma luna o lākou iho, a manuahi lākou," wahi āna.ʻO ka ʻokoʻa, hoʻomaʻamaʻa ʻia ke aniani optical i 100 nanometers, ʻoiai ʻo nā aniani o ka hae nui o NASA ʻo James Webb Space Telescope e hoʻonani ʻia i 20 nanometers.
Akā ʻaʻole manaʻo ka poʻe a pau e lilo kēia ʻano nani i mea hoʻopakele o nā piliona kānaka a puni ka honua.Ua kuhikuhi ʻo Polofesa Ady Arie mai ke Kula ʻOihana ʻElekene o ke Kulanui ʻo Tel Aviv, ʻo ke ʻano o Bercovici lāua ʻo Frumkin e koi ai i kahi pōʻai pōʻai e hoʻokomo ʻia ai ka polymer wai, ka polymer ponoʻī a me ke kukui ultraviolet.
"ʻAʻole loaʻa kēia ma nā kauhale India," i kuhikuhi ai ʻo ia.ʻO kekahi pilikia i hāpai ʻia e SPO Precision Optics ka mea hoʻokumu a me ka hope pelekikena o R&D Niv Adut a me ka ʻepekema poʻokela o ka hui ʻo Dr. Doron Sturlesi (ua kamaʻāina lāua i ka hana a Bercovici) ʻo ka hoʻololi ʻana i ke kaʻina wili me nā hoʻoheheʻe plastik e paʻakikī ke hoʻololi i ka lens i ka pono.Kona poe.
ʻAʻole hopohopo ʻo Berkovic."ʻO ka hoʻohewa he ʻāpana koʻikoʻi o ka ʻepekema, a ʻo kā mākou hoʻomohala wikiwiki ʻana i ka makahiki i hala ma muli o ka poʻe loea e koi ana iā mākou i ke kihi," wahi āna.E pili ana i ka hiki o ka hana ʻana ma nā wahi mamao, ua hoʻohui ʻo ia: "ʻO ka ʻōnaehana pono e hana i nā aniani me ka hoʻohana ʻana i nā ʻano kuʻuna he nui;Pono ʻoe i nā hale hana, nā mīkini, a me nā ʻenehana, a pono mākou i nā ʻoihana liʻiliʻi.
Ua hōʻike mai ʻo Bercovici iā mākou i ʻelua mau kukui radiation ultraviolet i kāna hale hana: “No Amazon kēia a he $4 ke kumukūʻai, a ʻo kekahi mai AliExpress a he $1.70.Inā ʻaʻole ʻoe iā lākou, hiki iā ʻoe ke hoʻohana i ka Sunshine i nā manawa a pau, "i wehewehe ʻo ia.Pehea nā polymers?"Ke kūʻai aku nei kahi hue 250-ml no $ 16 ma Amazon.Pono ka lens maʻamau i 5 a 10 ml, no laila ʻaʻole kumu maoli ke kumu kūʻai o ka polymer.
