Graphene, yomwe sinathebe

Kodi ndi kangati komwe timawona "nkhani zam'tsogolo" m'manyuzipepala, momwe zopambana zokonzekera zasayansi zopindulitsa chuma cha dziko zimalengezedwa monyadira? Nthawi zambiri mu ndemanga ku mauthenga oterowo ndi malipoti munthu angapeze kukayikira ndi kuyitana kuti alembe za zochitika zakale zokha. Tili ndi chikhulupiriro chochepa mu mapulani owala komanso olimbikitsa.

Chabwino, nkhani zapakhomo sizili zapadera m'mabuku amtunduwu. Sikovuta kukumana ndi zolengeza "zawo" za New Vasyukov.

Ndikupangira kuti ndifufuze tsogolo la polojekiti yaukadaulo yomwe yapanga kuphulika osati Kumadzulo kokha, komanso yafika pawailesi yakanema ya Chirasha. Ngati mumasewera bingo ya bullshit, ndikupatsani lingaliro pamaso pa kata - graphene.

Liti ndi zomwe zinalonjezedwa

M'mwezi wa Marichi 2019, idafalikira pama media achingerezi, makamaka aku Britain. mawu okweza kuchokera ku Paragraf. Mtsogoleri wamkulu komanso woyambitsa mnzake a Simon Thomas adalankhula bwino za kupita patsogolo kwakukulu pakupanga ma graphene. Malinga ndi iye, idakhazikitsidwa mu 2015 Chaka, Cambridge pulofesa Sir Colin Humphreys, Paragraf anatha kukhazikitsa ndondomeko khola luso kupanga graphene mu mawonekedwe a litayamba ndi awiri a ku 200 mm.

Kutengera zaka zambiri za kafukufuku ndi zaka zomwe adakhazikitsa njira yaukadaulo, Simon adalonjeza kuti ayamba kupanga zida zamafakitale pogwiritsa ntchito graphene mkati mwa miyezi iwiri ikubwerayi.

Zomwe zidatsogola lonjezolo

Inde, matekinoloje achilendo oterowo sangawonekere kunja kwa mpweya wochepa. Kupatula apo, zimphona monga IBM, Intel, Samsung, ndi magulu ena ambiri akugwira ntchito pamavuto opanga mafakitale a graphene. N'zokayikitsa kuti zinali zotheka ndi zofunika kupita patsogolo pawo mu mode chozemba. Chifukwa chake, titha kupeza zotsatira za zomwe adachita kale.

Mu 2017 kampaniyo adalandira ndalama £3 miliyoni kuphatikiza ndalama za boma. Ndalamazi zidapangidwa kuti apange ma prototypes ndikuwongolera ukadaulo (ndiroleni ndikukumbutseni kuti kampaniyo idakhazikitsidwa mu 2015, ndipo kafukufuku yemwe adapangitsa kuti gawo lazamalonda likhale lofunika lidachitika kale).

Mu Meyi 2018 kampaniyo adalandira gawo lina ndalama. Panthawiyi kukula kwake kunali £ 2,9 miliyoni, ndipo pakati pa osunga ndalama sanali makampani opangira ndalama zokha, komanso thumba la bizinesi la Cambridge. Tsopano sizinalinso za kukonza luso lamakono. Cholinga cha ndalamazo ndikutsegula malo opangira kuti ayambe kupanga zida zochokera ku graphene. Adakonza zoyambira ndi masensa apamwamba kwambiri a maginito ndi masensa ena omwe amapangidwira msika waukulu.

Pafupifupi chaka chotsatira, mu Marichi 2019, panali mawu akuti zonse zakonzeka ndikukhazikitsidwa. Kwenikweni, m'miyezi ingapo, zida za graphene zidzayamba kupangidwa mochuluka, kugulidwa pamsika, ndipo nyengo yatsopano idzayamba. Nkhani yokwezeka imeneyi, yokhala ndi nthawi yodziwika (ngakhale yosadziwika bwino), inalandiridwa bwino ndipo inafika kwa owerenga athu apanyumba.

Zomwe zidachitika komanso zomwe sizinachitike pambuyo pa hype

Wowerenga wanzeru amatha kuganiza zomwe zidachitika pambuyo pa phokoso lotere komanso chidwi cha media. Chabwino, ndikupatsani malingaliro ena. Ndime adatseka gawo lina lazachuma kuchokera kundalama zomwezo, atalandira kale $ 12,8 miliyoni. M'mwezi womwewo, kuyambitsa (komwe kampani yazaka 2019 ingatchulidwe kuti yoyambira) idayamba. kupatsidwa mphoto £0,5 miliyoni kuti zitukuke.

Chimene sichinachitike nthawi yapitayi ndi kusintha kolonjezedwa ndi kuyamba kwa kupanga kwakukulu. Miyezi 8 ndi theka yadutsa kale kuchokera pamene lonjezo loti liyambe kupanga zinthu zambiri mkati mwa miyezi 2-3, koma masensa omwe adalengeza ndi omasulira (omwe ali ndi mphamvu 30 kuposa omwe amagwiritsidwa ntchito) sanalowe mumsika.

Masamba 5 oyamba akusaka kwa Google ndi tabu ya "Nkhani" amangowonetsa mawu okweza okha okhudza kukonzekera kuyambitsa malonda a zida za graphene "miyezi ingapo ikubwerayi" kuyambira Marichi 2019, komanso nkhani za Julayi kulandira ndalama zokwana £12,8 miliyoni.

Sizingatheke kupeza chidziwitso chilichonse chokhudza kukhazikitsidwa kwenikweni kwa kupanga kulikonse kapena kuperekedwa kwa zigawo za gulu lachitatu. Komanso, tsamba la kampaniyo lasiya kugwira ntchito, ngakhale atolankhani adazitchulanso mu Seputembala.

Mkhalidwe wapano

Kampaniyo yalandira ndalama kuyambira 2017 zosachepera $ 19,2 miliyoni (1,6 biliyoni ma ruble pamtengo wosinthira pano). Mu Seputembala 2019, gulu la kampaniyo linaphatikizapo ofufuza 25 (mu Marichi anali 16), ndipo, kutengera mawu a woyambitsa, akupangabe ndikukonzekera kuyambitsa kupanga ma sensor maginito ozizwitsa ndi masensa ena. Nkhani zaposachedwa za iwo zimatha mu Seputembala. webusaiti tsopano sizikugwiranso ntchito (upd. kupezeka kudzera pa VPN).

Pakadali pano, kwinakwake akusonkhanitsa ndalama zotsatila za mabatire osintha, ma conductor, masensa ndi masensa. makondomu ena, tikukupatsirani kuchotsera pazinthu zomwe zasintha kale. Zinanditengera maola angapo kuti ndifufuze magwero ndikukonzekera zinthuzo, ngakhale mwayi pang'ono; nkhaniyo itandigwira m'maso, ndidasunga ndikukumbukira nthawi yoyenera. Koma zonsezi zikhoza kuchitika ndi makina kumbuyo, omwe amagwiritsidwa ntchito kale ndi mabungwe ambiri ndi magulu owunikira. Titsatireni!
