Ymchwil
Prif ddiddordeb ei waith yw optimeiddio prosesau catalytig ar systemau heterogenaidd, arwynebau estynedig neu nanoronynnau. Yn bennaf, mae ganddo ddiddordeb yn y canlynol:
- Dal a defnyddio CO2
- Ynni adnewyddadwy a glân
- Dylunio deunydd, gan gynnwys gweithgynhyrchu rheolaeth atomig.
- Sintering a coalescence o nanostructures
Er mwyn deall yr agweddau hyn, mae'n gwerthuso'r cydbwysedd rhwng cineteg a thermodynameg, gan ddibynnu ar dechnolegau cyfrifiadurol i efelychu amodau'r adweithydd. Mae'r rhain wedi arwain at ostyngiadau mewn costau datblygu, amser byrrach i'r farchnad, a dylunio a datblygu deunyddiau mwy effeithlon. Mae cymhwyso methodolegau cyfrifiadurol fel ab initio, mecaneg cwantwm / efelychiadau mecaneg moleciwlaidd, neu fodelau continwwm polariadwy yn darparu rheolaeth hawdd o'r paramedrau sy'n effeithio ar y prosesau, gan arwain at ddealltwriaeth lefel atomig o'r broses.
