Arif Hidayat,Rochmadi,Karna Wijaya,Annisa Nurdiawati,Winarto Kurniawan,Hirofumi Hinode,Kunio Yoshikawa,Arief Budiman +7 more
TL;DR: In this article, the authors used a coconut shell biochar (CSB) catalyst to convert free fatty acids (FFA) into biodiesel, and the optimal conditions were an methanol/PFAD molar ratio of 12:1, the amount of catalyst of 7%wt and reaction temperature of 60oC.
Journal ArticleDOI
DNA binding of iron(II) complexes with 1,10-phenanthroline and 4,7-diphenyl-1,10-phenanthroline: salt effect, ligand substituent effect, base pair specificity and binding strength.
TL;DR: The iron(II) complexes studied have higher affinity towards the more facile A-T sequence than the G-C sequence, which may be attributed to the steric effect induced by the ancillary part of the ligands in the course of DNA binding.
Journal ArticleDOI
Composites of TiO2-aluminum pillared montmorillonite: Synthesis, characterization and photocatalytic degradation of methylene blue
TL;DR: In this paper, aluminum pillared montmorillonite was used as a porous support for the synthesis of TiO2-based photocatalysts with varying TiO 2 loading and the titania content in the composites significantly influenced the physicochemical properties and catalytic activity.
Journal ArticleDOI
Pt-promoted sulfated zirconia as catalyst for hydrocracking of LDPE plastic waste into liquid fuels
TL;DR: In this article, the authors focused on the preparation of Pt-promoted sulfated zirconia (Pt/SZ) and study the effect of different concentrations of Pt on SZ for hydrocracking reaction of LDPE plastic waste.
Journal ArticleDOI
Base-specific and enantioselective studies for the DNA binding of iron(II) mixed-ligand complexes containing 1,10-phenanthroline and dipyrido[3,2-a:2′,3′-c]phenazine
TL;DR: It is a surprising observation that the enantioselectivity of the DNA binding for [Fe(phen)2(dppz)]2+ is base-dependent in nature.
