Surface Chemistry & Kuedzwa kweSurfaces & Surface Kugadziriswa uye Kuvandudza

Mutsara wekuti "Surfaces anofukidza zvese" ndeumwe watinofanira kupa sekondi yekufunga nezvawo. Sainzi yepasi chidzidzo chezviitiko zvemuviri nekemikari zvinoitika pakusangana kwezvikamu zviviri, zvinosanganisira solid-liquid interfaces, solid-gas interfaces, solid-vacuum interfaces, uye liquid-gasi interfaces. Inosanganisira minda yepamusoro chemistry uye yepamusoro fizikisi. Zvinoenderana zvinoshanda zvikumbiro zvinozivikanwa pamwe chete sepamusoro engineering. Surface engineering inosanganisa pfungwa dzakadai seheterogeneous catalysis, semiconductor mudziyo wekugadzira, masero emafuta, anozvibatanidza ega monolayers, uye zvinonamira.

 

Surface chemistry inogona kutsanangurwa zvakafara sechidzidzo chemakemikari maitikiro pazvinopindirana. Iyo ine hukama hwepedyo nehuinjiniya hwepamusoro, iyo ine chinangwa chekugadzirisa kemikari yepasi nekubatanidza zvinhu zvakasarudzwa kana mapoka anoshanda anoburitsa akasiyana anodiwa mhedzisiro kana kuvandudzwa kwezvinhu zvepasi kana interface. Sainzi yepamusoro inonyanya kukosha kuminda senge heterogeneous catalysis uye matete firimu machira.

 

Kudzidza uye kuongororwa kwenzvimbo kunosanganisira zvese zvemuviri uye makemikari ekuongorora maitiro. Nzira dzinoverengeka dzemazuva ano dzinoongorora iyo yepamusoro-soro 1-10 nm yenzvimbo dzakafumurwa vacuum. Izvi zvinosanganisira X-ray photoelectron spectroscopy (XPS), Auger electron spectroscopy (AES), low-energy electron diffraction (LEED), electron energy loss spectroscopy (EELS), thermal desorption spectroscopy, ion scattering spectroscopy, yechipiri ion mass spectrometry (SIMS) , uye dzimwe nzira dzekuongorora pamusoro. Mazhinji emaitiro aya anoda vacuum uye midziyo inodhura sezvo ichivimba nekuona maerekitironi kana maion anoburitswa kubva pamusoro pekudzidza. Kunze kweakadaro emakemikari matekiniki, emuviri kusanganisira optical matekiniki anoshandiswa zvakare.

​

Kune chero mapurojekiti angangoita einjiniya anosanganisira nzvimbo, zvinonamira, kukwidziridzwa kwekunamira kune pamusoro, kugadziridzwa kwepasi kugadzira nzvimbo hydrophobic (yakaoma kunyorova), hydrophillic (kunyorova kunyorova), antistatic, antibacterial kana antifungal ... nezvimwewo, taura nesu nemasaenzi edu epamusoro. ichakubatsira mukugadzira kwako uye kuedza kwekusimudzira. Isu tine ruzivo rwekuona kuti ndeapi matekiniki ekushandisa kuongorora yako imwe nzvimbo pamwe nekuwana kune yakanyanya bvunzo michina.

​

Mamwe masevhisi atinopa ekuongorora pamusoro, kuyedzwa uye kugadzirisa ndeaya:

• Kuedzwa uye hunhu hwenzvimbo

•  Kugadziriswa kwenzvimbo uchishandisa nzira dzakakodzera dzakadai seflame hydrolysis, plasma surface treatment, deposition of functional layers….etc.

• Kuvandudzwa kwemaitiro ekuongororwa kwepamusoro, kuyedzwa uye kugadzirisa

• Sarudzo, kutenga, kugadziridzwa kwepamusoro kurapwa uye gadziriso yemidziyo, maitiro uye maitiro ekushandisa

• Reverse engineering yekurapa kwepamusoro kune yakakosha maapplication

• Kukurura & kubviswa kweakatadza akaonda firimu zvimiro uye machira kuti aongorore ari pasi penzvimbo kuti aone midzi chikonzero.

• Nyanzvi dzeuchapupu uye mabasa ematare

• Consulting services

 

Isu tinoita gadziriso yepamusoro kune akasiyana maapplication, kusanganisira:

• Kuvandudza kunamatira kwekuputira uye substrates

• Kugadzira nzvimbo hydrophobic kana hydrophilic

• Kugadzira nzvimbo antistatic kana static

• Kugadzira nzvimbo dzeantifungal uye antibacterial

 

Mafirimu akaonda uye Coatings

Mafirimu akatetepa kana machira akatetepa zvinhu akaturikidzana kubva kuzvikamu zve nanometer (monolayer) kusvika kune akati wandei mamicrometer mukukora. Electronic semiconductor zvishandiso, optical coatings, scratch resistant coatings mamwe makuru maapplication ari kubatsirwa kubva mutete firimu kuvaka.

 

Kushandiswa kunozivikanwa kwemafirimu matete ndiyo girazi repamba iro rinowanzo kuve nesimbi yakatetepa yekumisikidza kuseri kwepepa regirazi kuti iite inotaridzika. Nzira yesirivha yaimboshandiswa kugadzira magirazi. Mazuva ano akawanda epamberi matete firimu coatings ari kushandiswa. Semuenzaniso, bhaisikopo rakaonda kwazvo (risingasviki nanometer) rinoshandiswa kugadzira magirazi maviri. Kuitwa kwemachira ekuona (senge antireflective, kana AR coatings) anowanzo wedzerwa kana iyo yakatetepa firimu coating ine akawanda akaturikidzana ane hukobvu hwakasiyana uye refactive indices. Zvakafanana nguva nenguva zvimiro zvekuchinjanisa mafirimu matete emhando dzakasiyana-siyana zvinogona pamwe chete kuumba inonzi superlattice iyo inoshandisa chiitiko chekuvharirwa kwehuwandu nekudzora zviitiko zvemagetsi kune maviri-dimensi. Mamwe mashandisirwo eakaonda emufirimu akapfava ferromagnetic akatetepa mafirimu ekushandisa seyekombuta yekurangarira, mutete firimu dhizaini dhizaini rinoiswa kune mishonga, yakatetepa-firimu mabhatiri. Ceramic matete mafirimu zvakare ari mukushandiswa kwakapararira. Iyo yakanyanya kuomarara uye inertness yezvinhu zveceramic inoita aya marudzi akatetepa machira ekufarira kudzivirira ye substrate zvinhu kubva mukuora, oxidation uye kupfeka. Kunyanya, kushandiswa kwemajasi akadaro pakucheka zvishandiso kunogona kuwedzera hupenyu hwezvinhu izvi nemirairo yakawanda yehukuru. Tsvagiridzo iri kuitwa pazvikumbiro zvakawanda. Muenzaniso wekutsvakurudza ikirasi itsva yefirimu yakaonda inorganic oxide zvinhu, zvinodaidzwa kuti amorphous heavy-metal cation multicomponent oxide, iyo inogona kushandiswa kugadzira transistors yakajeka isingadhuri, yakagadzikana, uye ine nharaunda isina kunaka.

 

Sezvimwe chero chidzidzo cheinjiniya, nzvimbo yemafirimu matete inoda mainjiniya kubva kwakasiyana siyana, kusanganisira mainjiniya emakemikari. Tine zviwanikwa zvakatanhamara munzvimbo ino uye tinogona kukupa anotevera masevhisi:

• Firimu yakaonda & coatings dhizaini nekusimudzira

• Firimu rakatetepa & mabhanditi hunhu anosanganisira kemikari uye analytical bvunzo.

• Kemikari uye kuiswa kwemuviri kwemafirimu matete & machira (plating, CSD, CVD, MOCVD, PECVD, MBE, PVD senge sputtering, reactive sputtering, uye evaporation, e-beam, topotaxy)

• Kuburikidza nekuvaka kweakaomesesa akaonda firimu zvimiro, isu tinogadzira multimaterial zvimiro senge nano-composites, 3D zvimiro, akaturikidzana eakasiyana akaturikidzana, akawanda,…. etc.

• Maitiro ekuvandudza uye optimization kune yakaonda firimu uye coating deposition, etching, kugadzirisa

• Kusarudzwa, kutenga, kugadziridzwa kwefirimu rakatetepa uye coating process uye maitiro ekushandisa

• Reverse engineering yemafirimu matete uye machira, kemikari uye yemuviri ongororo yezvikamu mukati memultilayer coating zvimiro kuti zvione makemikari zvirimo, zvisungo, chimiro uye zvivakwa.

• Root chikonzero kuongororwa kweakakundikana akaonda firimu zvimiro uye machira

• Nyanzvi dzeuchapupu uye mabasa ematare

• Consulting services
