Sumalin Phoka,Paveena Laokul,Ekaphan Swatsitang,Vinich Promarak,Supapan Seraphin,Santi Maensiri +5 more
TL;DR: In this paper, a simple polymer complex method using cerium (III)) acetate hydrate and polyvinyl pyrrolidone (PVP) as the starting chemicals was used to synthesize CeO 2 nanoparticles.
Journal ArticleDOI
Egg White Synthesis and Photoluminescence of Platelike Clusters of CeO2 Nanoparticles
Santi Maensiri,Chivalrat Masingboon,Paveena Laokul,Wirat Jareonboon,Vinich Promarak,and Philip L. Anderson,Supapan Seraphin +6 more
TL;DR: In this article, a plate-like structure of CeO2 nanoparticles having the particle size of 6−30 nm was obtained by calcining the precursors in air at 400, 500, and 600 °C, for 2 h.
Journal ArticleDOI

TL;DR: A series of organic sensitizers with the direct electron injection mechanism and a high molar extinction coefficient comprising double donors, a π-spacer, and anchoring acceptor groups (D−D−π-A type) were synthesized and characterized by experimental and theoretical methods for dye-sensitized solar cells.
Journal ArticleDOI
Biodiesel production from palm oil using hydrated lime-derived CaO as a low-cost basic heterogeneous catalyst
TL;DR: In this paper, hydrated lime-derived calcium oxide (CaO) was used as a catalyst for the transesterification of palm oil, and the results showed that the catalysts were characterized by TG-DTA, XRD, XRF, FT-IR, SEM, TPD-CO2 and BET by N2 adsorption.
