Effects of the duration of ultrasonic irradiation and the atmospheric environment on the characteristics of zno nanostructures via a sonochemical method / W. Widiyastuti, Siti Machmudah, Tantular Nurtono, Sugeng Winardi
" Nanostructured zincoxide (ZnO) was synthesized via a sonochemical method. The effect of the duration of ultrasonic irradiation in a continuous mode on the generated particles was investigated. Additionally, the effect of flowing either air or nitrogen during the sonication process was investigated. Zinc nitrate and ammonia water-based solutions were selected as chemicals without the addition of other surfactants. The generated particles indicated that a wurtzite structure of ZnO in a hexagonal phase was formed with a crystalline size ... "

Preparasi dan karakterisasi komposit terbium tetraetilena glikol pikrat untuk aplikasi fotosensor
" Fabrikasi kompleks Tb[EO4-Pic] ke dalam bentuk mikropartikel dengan metode represipitasi-penguapan telah berhasil dilakukan dalam penelitian ini, dimana EO4 = tetraetilena glikol, Pic = anion pikrat. Untuk perbandingan dikaji juga fabrikasi dengan metode In situ. Mikropartikel kompleks Tb[EO4-Pic] yang dihasilkan didispersikan ke dalam matriks polimer polimetilmetaakrilat (PMMA) menjadi komposit Tb[EO4-Pic]/PMMA. Komposit dilapiskan pada substrat dengan teknik spin-coating. Pada penelitian ini dikaji juga pengaruh polimer dan substrat terhadap sifat luminesensi dari mikropartikel kompleks Tb[EO4-Pic] dan kompositnya. Ukuran ... "
