Simulasi model termodinamik pengolahan debu filter hasil proses pembuatan baja pada tanur busur listrik dengan program komputer ChemSage
" ABSTRAK
Debu filter yang dihasilkan pada proses pembuatan baja melalui tanur busur listrik, saat ini pada negara-negara maju dikategorikan sebagai limbah yang berbahaya. Salah satu teknologi yang menawarkan pengolahan debu filter ini adalah proses HTM (High Turbulence Mixer). Pada proses ini debu filter -tanpa proses aglomerisasi- dimasukkan ke dalam besi/baja cair yang terdapat pada reactor. Beberapa oksida seperti ZnO, PbO dan FeO akan tereduksi sementara CaO, SiO2, MnO, P205 dan AI203 akan masuk ke terak yang ... "

Optical transmittance, electrical resistivity and microstructural characteristics of undoped and fluorine-doped tin oxide conductive glass fabricated by spray pyrolysis technique with modified ultrasonic nebulizer
" Fluorine-doped tin oxide (FTO) is one of the conductive glasses that have strategic functions in various important applications, including dye-sensitized solar cell (DSSC). In the current work, the effects of deposition time (5, 10, 20, 30, and 40 minutes) upon the fabrication process of FTO thin film using spray pyrolysis technique with modified ultrasonic nebulizer has been studied in regard to its microstructural, optical, crystallinity, and resistivity characteristics. The variation was also performed by comparing ... "

The influence of deposition time and substrate temperature during the spray pyrolysis process on the electrical resistivity and optical transmittance of 2 wt% fluorine-doped tin oxide conducting glass
" Transparent conducting oxide (TCO) glasses play an important role in various technology, including dye sensitized solar cells. One of the most commonly used glass is indium tin oxide (ITO) glass, which is expensive. Therefore, the main purpose of this research was to determine if ITO glass can be replaced with fluorine-doped tin oxide (FTO) glass, which is easier and more economic to manufacture. For this purpose, a tin chloride dehydrate (SnCl2.2H2O) precursor was doped with ammonium fluoride (NH4F) using a sol-gel method and spray pyrolysis ... "
