Trosolwyg
Mae diddordebau ymchwil Dr Dlamini yn canolbwyntio ar ddealltwriaeth sylfaenol o adweithiau catalyzed sy'n berthnasol i gynhyrchu tanwydd cludo glân, cemegau nwyddau ac adfer llygryddion sy'n cael ei yrru gan yr haul. Mae'r dull hwn yn cynnwys cael mewnwelediad ar y rhyngwyneb cymorth metel, y safleoedd gweithredol sy'n bresennol yn y deunydd swyddogaethol yn ogystal â'r mecanwaith ymateb. Yn nodweddiadol, gwneir astudiaeth o ddeunyddiau catalydd confensiynol ochr yn ochr â systemau model tunadwy fel carbonau ac ati. Gweler ein cyhoeddiadau diweddar am fwy o fanylion.
