Lub University of Hong Kong tau ua tiav tau npaj ntau cov cim ntawm pob zeb diamond

Associate Profession Chu Zhiqin pawg thiab xibfwb Xin Woob Qhov thev naus laus zis no tau txhim kho cov ntaub ntawv thov ntawm pob zeb diamond hauv ntau thaj teb xws li optics, quartum tshuab, thiab thev naus laus zis.

 

Pob zeb diamond tsis yog tsuas yog paub dav hauv cov hniav nyiaj hniav kub, tab sis kuj tseem muaj cov khoom siv hluav taws xob, xws li cov khoom siv hluav taws xob, cov thermal conductivity, dav bandgap, thiab biocompatibility. Ntawm micro thiab nano teev, geometric cov duab thiab cov qauv ntawm pob zeb diamond ncaj qha cuam tshuam ncaj qha rau lawv cov kev ua tau zoo thiab kev thov ua tiav. Txawm li cas los xij, vim muaj tshuaj lom neeg inertness thiab kev nyuaj ntawm lub pob zeb diamond, thiab cov kev txwv ntawm cov cuab yeej muaj tshuab thiab cov qauv kev ua kom zoo nkauj thiab cov qauv muaj ib txwm ntsib ntau yam kev nyuaj. Yog li ntawd, yuav ua li cas thiaj li tswj tau cov morphology thiab cov qauv saum npoo ntawm pob zeb diamond tau dhau los ua qhov teeb meem tseem ceeb uas cov kws tshawb fawb tau daws.

 

Txhawm rau hais txog cov teeb meem no, pab pawg ntawm Associate xibfwb Chu Zhiqin thiab xibfwb Lin Yuan tau thov kev tshawb fawb tshiab hauv lawv cov kev tshawb fawb tshiab: "Programmable nanocar nanocar. Xav txog cov pob zeb diamond uas muaj cov qauv crystal sib txawv, thiab cov qauv tshawb pom yooj yim, tuaj yeem ua tiav cov pa hluav taws xob yooj yim, tuaj yeem ua tiav oxidizing tshwj xeeb crystal qauv Cov. Cov qauv no yog cov kev xaiv thawj zaug (suav nrog cov noob, thiab cov kev sim ua kom haum), thiab cov pa roj oxidation rov kho cov pob zeb diamond. Pawg neeg tshawb fawb tau ua tiav tau ua tiav ntau cov txiaj ntsig ntawm cov cim zeb, sib npaug ntawm cov ntsej muag, convered conical, nanoflower, thiab ntxeem cov duab. Los ntawm cov kev sim ua pov thawj kev sim thiab kev sim ua kom pom tseeb, cov duab tsim qauv tau tsim los coj cov qauv tsim, thiab cov tswv yim thov kev siv cov pob zeb diamond.

Tsis zoo li kev ua lub cev nqaij daim tawv lossis cov khoom siv tshuaj lom neeg, cov qauv ntawm cov tshuab hluav taws xob kom raug rau cov kws kho hniav hluav taws xob kom raug, kho qhov muag ntawm pob zeb diamond, qhib nce cov zeem muag Rau pob zeb diamond cov ntaub ntawv hauv cov ntawv thov tshiab. Piv txwv li, hauv tshav pob ntawm Optics, rov kho pob zeb diamond sau tuaj yeem siv los ua cov khoom siv kho qhov muag zoo heev los txhim kho kev ua haujlwm thiab kev ua tau zoo ntawm cov khoom siv kho qhov muag; Hauv kev tawm tsam thev naus laus zis, txawv cov duab pob zeb diamond tuaj yeem siv tau los tsim cov ntawv tsis yooj yim, yog li tiv thaiv kev ruaj ntseg ntawm cov khoom lag luam. Daim ntawv thov cov kev cia siab ntawm cov pob zeb diamond tshiab ua rau cov thev naus laus zis ntawm cov khoom siv tshiab thiab ntau daim teb kev siv.

 

Pab pawg tshawb fawb ntseeg tias kev vam meej ntawm no nano carvingas tsis tsuas yog muab cov tswv yim tshiab thiab cov hau kev tshiab rau cov khoom siv cuav thiab cov ntawv thov ntawm cov khoom siv nano. Nyob rau tib lub sijhawm, nws kuj tseem yuav muab cov ntaub ntawv tseem ceeb rau kev txhim kho kev lag luam ntsig txog kev lag luam. Nrog rau kev txhim kho ntxiv ntawm cov thev naus laus zis no, nws yuav tsum ua ib lub luag haujlwm tseem ceeb tshaj plaws hauv kev teb Nanotechnology, quantum tshuab, thiab cov ntaub ntawv ua haujlwm siab.
