Studi penentuan distribusi ukuran nanopartikel platina menggunakan mikroelektroda hydrogenated boron doped diamond (hbdd) dan oxidized boron doped diamond (OBDD) dengan hidrogen peroksida = Study on determination of platinum nanoparticles sized distribution using hydrogenated boron doped diamond (HBDD) and oxidized boron doped diamond (obdd) microelectrodes with hydrogen peroxide
" Mikroelektroda hydrogenated boron doped diamond (HBDD) dan oxidized boron doped diamond (OBDD) digunakan dalam studi penentuan distribusi ukuran nanopartikel Pt. Studi dilakukan menggunakan teknik kronoamperometri pada potensial tetap 0,516 V dengan mengamati arus transien yang muncul pada reaksi oksidasi hidrogen peroksida 1 mM dalam phosphate buffer solution (PBS) 50 mM sebagai hasil reaksi elektrokatalitik oleh nanopartikel Pt ketika menumbuk permukaan mikroelektroda. Batas minimum arus transien yang dideteksi oleh mikroelektroda HBDD dan OBDD masing-masing adalah 1,5 ... "

Desorption temperature characteristic of mg-based hydrides catalyzed by nano-sio2 prepared by high energy ball milling
" Magnesium-based hydrogen storage alloy is one of the most attractive hydrogen storage materials for fuel cell-powered vehicle application. However, a high desorption temperature and slow kinetics limit its practical application. Extensive efforts are required to overcome these problems, one of which is inserting a metal oxide catalyst. In this work, we reported the current progress of using nano-silica (SiO2) as a catalyst to improve the thermodynamics and kinetics of magnesium hydride (MgH2). Nano-SiO2 was extracted ... "
