Recently the applications of functionalized magnetic nano particles are increased in a linear fashion. This is due to the ease of synthesis and controlled growth of magnetic nano particles. In the present investigation gentamicin drug functionalized Fe3O4 nanoparticles were synthesized by co-precipitation method. Thus obtained nano hybrid was characterized by Fourier transform infrared (FTIR) s...

A layered organic-inorganic intercalate was prepared by the self-assembly technique using pamoate (PA) as an organic guest in the Zn-Al layered double hydroxide inorganic host (ZAPAN). Various concentrations of PA, ranging from 0.01 to 0.04 M, were used to prepare the intercalated compound with a constant 4:1 ratio of Zn:Al in the mother liquor. The concentration of PA of 0.02 M at pH 7 was fou...

SrBi4Ti4O15 is one of four-layered Aurivillius compound family member that can be used as photocatalyst material works in the violet light region. To expand its work function range conducted by doped with metal elements to results reduced band gap energy. In this research, we synthesized vanadium (SrBi4Ti4-nVnO15 (n= 0, 0.05, 0.1, and 0.15)) molten salt method (used KCl salt). The diffractogram...

Catalysts have an essential role in chemical processes because they can control reactions and produce the desired product. In general, catalysts function to speed up that take place by lowering activation energy. By decreasing energy, minimum energy required for collision is reduced so reaction occur faster. Selection of suitable material be used as a catalyst effort must made achieve successfu...

In this era, most technology requires electronic equipment. The performance of equipment may be affected by energy storage components like a supercapacitor, so the development supercapacitor electrode materials using green chemical methods needs to pursued. Material with good specific capacitance is MnO2. Most MnO2 synthesis are not based on chemistry, there an alternative method. One them util...

Purpose: To evaluate physicochemical changes in ciprofloxacin following incorporation in Carbopol polymeric composites. Methods: The ciprofloxacin and Carbopol were mixed in water in a drug:polymer ratio of 1:5 (w/w) and homogenized to produce uniform composites. X-ray powder diffraction analysis of the pure ciprofloxacin and the Carbopol polymeric composites of the drug were obtained using a p...
