Curcumin is a secondary metabolite that has diverse biological activities. However, curcumin has low bioavailability due to the presence of the β-diketone unit is easily hydrolyzed at physiological pH. Therefore the replacement of the unit with monoketone is expected to overcome this problem. We hereby report the synthesis of the piperidone derivative monoketone curcumin analogs. Synthesis was…

Nanostruktur TiO2/Co3O4 Sebagai Fotoanoda Pada Proses Pemisahan Molekul Air
Titanium dioxide is one of the most investigated materials for photoelectrochemical (PEC) water splitting. However, TiO2 has a wide band gap of approximately 3.2 eV, which limits its absorption energy to UV only, and the photoexcitation products (i.e., electron and hole) easily recombine. Developing a composite with other semiconductor materials is one of the efforts for improving the performa…
