Trosolwyg
Mae gennym ddiddordeb yn y prosesau wyneb sylfaenol sy'n sail i ffenomenau fel catalysis, cyrydiad a glynu. Mae'r rhain yn cael eu dylanwadu gan lawer o wahanol ffactorau ac felly mae'n rhaid i'n gwaith gwmpasu agweddau megis cyfansoddiad elfennol, cemeg a thopograffeg arwyneb. Mae cymhwysedd eang ein hymchwil yn dystiolaeth o'r amrywiaeth eang o gydweithrediadau yr ydym yn ymwneud â hwy gan gynnwys grwpiau mewn Fferylliaeth, Peirianneg, Biowyddoniaeth, Archaeoleg a Gwyddorau Daear.
Mae ein harbenigedd yn cynnwys:
·Microsgopeg Llu Photoinduced (PiFM) Sbectrosgopeg is-goch o arwynebau gyda datrysiad ochrol 5 nm
·Spectrosgopeg ffotoelectron pelydr-X (XPS) sy'n darparu gwybodaeth gemegol ar yr wyneb
· Microsgopeg Atomic Force (AFM) ar gyfer delweddu di-ddargludyddion o'r nanometr i'r lefel micromedr
·Microsgopeg Twnelu Sganio (STM) ar gyfer delweddu sy'n cynnal strwythurau arwyneb ar gydraniad atomig
Rydym hefyd yn cynnal ymchwil ym maes ffotocatalysis ac o 2012-2016, cydlynais gonsortiwm FP7 PCATDES a oedd yn cynnwys ymchwilwyr o'r DU, yr Almaen, Sbaen, Twrci, Gwlad Thai, Malaysia a Fietnam. Datblygodd y prosiect prototeip adweithyddion ffotocatalytig ar gyfer puro dŵr.
Roeddwn i'n gyfarwyddwr sefydlu'r EPSRC National Research Facility yn Photoelectron Spectroscopy "HarwellXPS", yn 2017 sy'n cynnig XPS, UPS ac ISS o'r radd flaenaf i'r gymuned. Ar hyn o bryd rwy'n gyfarwyddwr HarwellXPS.
Rydym yn rhan o Sefydliad Catalysis Caerdydd

Ymchwil
Ein prif ddiddordeb yw deall sut y gall arwyneb addasu neu gyfarwyddo adwaith cemegol gyda diddordeb arbennig mewn catalysis heterogenaidd lle mae'r wyneb wedi cael ei gydnabod ers amser maith yn hanfodol wrth bennu gweithgarwch, detholrwydd ac oes. Fodd bynnag, mae cemeg wyneb yn rhan annatod o bron pob system heterogenaidd ac felly mae ein gwaith hefyd yn berthnasol i agweddau ar lyniant, cyrydiad a gweithgarwch biolegol. Mae craidd ein gwaith wedi bod yn ymwneud â deall ymatebion moleciwlau ar arwynebau a nodweddir yn gemegol ac yn strwythurol ar y lefel atomig.
Calon ein hymchwil yw ein harbenigedd mewn sbectrosgopeg ffotoelectron (roeddwn yn Gyfarwyddwr sefydlu'r Cyfleuster Ymchwil Cenedlaethol EPSRC llwyddiannus iawn mewn Spectrosgopi Ffotoelectron (HarwellXPS)) a sbectrosgopeg dirgryniadol nanoraddfa, mae gennym yr unig ficrosgop grym a achosir gan Lun yn y DU sy'n darparu datrysiad ochrol 5 nm a chymwysiadau is-goch yn unrhyw le mae angen cemeg leol arwyneb neu ryngwyneb.
Mae agweddau eraill ar ein gwaith yn cynnwys astudio mecanwaith ffotocatalysis, ac yn benodol rhannu dŵr; sy'n nodweddu'r llwybrau dadelfennu ar gyfer haearn archeolegol (cydweithio â'r Ysgol Gadwraeth); ymchwilio i synwyryddion polymerig newydd (cydweithio â'r Ysgol Fferylliaeth) ac archwilio priodweddau gwrthfacterol arian nanogronynnol (cydweithrediad â'r Ysgol Fferylliaeth)
I gael rhagor o wybodaeth am brosiectau penodol sydd ar gael gyda'r Athro Philip Davies, adolygwch adran Catalysis a gwyddoniaeth ryngwyneb ein themâu prosiect ymchwil.
