Abstract

Ferrofluids for temperature sensor application become one of the important modern technology applications. Therefore, the development of the beach sand-based ferrofluids for temperature sensor becomes new and essential things for cutting off their production. In this research, the preliminary investigation of the temperature sensor is developed based on the chromium ferrite ferrofluids. The sample in powder and fluid were prepared by coprecipitation-sonochemical technique.   The powder sample which was characterized by XRD has the crystallite size of 10 nm with high purity. The preliminary investigation shows that the chromium ferrite ferrofluid has a good property as a candidate for temperature sensor application showing a good response on the temperature treatmentDOI: http://dx.doi.org/10.17977/um024v3i12018p001

Abstract

Zinc oxide (ZnO) nanoparticles have been investigated intensively related to their applications such as in optical band gap energy for semiconductor application. In general, the characterization of band gap energy of the ZnO nanoparticles has been carried out using UV-Vis spectroscopy. In this work, ionization energy-tight binding model was developed to analyze the optical binding energy of the ZnO nanoparticles. The primary technique of the electronic structure calculation was an analytical calculation of overlap integral of 2p orbital from O and 3d orbital from Zn. The result of the calculation presents that the maximum bandgap energy of ZnO particles is about of 4.4 eV. This result is almost similar to band gap energy of the ZnO nanoparticles showing by experimental result. DOI: http://dx.doi.org/10.17977/um024v3i22018p038

Abstract

TiO2 is a semiconductor material that widely applied in various fields due to its superiority both in terms of physical and chemical properties. In this study, the TiO2 nanoparticles was synthesized using sol-gel method. The synthesis of TiO2 nanoparticles was started by reacted TiCl3 with aquades and titrated with ammonium hydroxide and then followed by calcination process at 600 0C for 1.5 hours. The structural characteristics were investigated using XRD. The fungsional groups of the TiO2 nanoparticles were characterized by FTIR. The optical properties of the TiO2 nanoparticles were determined using UV-Vis spectrometer. The morphology of the sample was characterized using SEM. The results show that the TiO2 has structure as anatase phase. The data analysis using the Scherrer’s equation show that the particle crystallite size of is about of 9.77 nm. The energy band gap value of the TiO2 is 3.28 eV. Based on the SEM image, the agglomeration of the sample was formed with the average diameter of particle size of TiO2 is about 92 nm.DOI: http://dx.doi.org/10.17977/um024v3i12018p008

Abstract

Dye Sensitized Solar Cell (DSSC) merupakan salah satu bagian dari energi terbarukan yang memiliki potensi besar dengan memanfaatkan energi dari sinar matahari menjadi energi listrik dengan bantuan sensitizer sebagai agen penyerap cahaya. Kemampuan konversi DSSC ditunjukkan oleh nilai Jsc (12,70 mA/cm2), Voc (0,585 V), FF (0,476), dan η (3,54%) yang diperoleh dari pengujian solar simulator. Selain parameter tersebut, karakteristik DSSC dapat juga ditunjukkan dari nilai ttr (0,010 s), trec (0,080 s), ηcc (0,874), D (0,192) dan  LD  (0,124 mm) melalui IMPS (Intensity Modulated Photocurrent Spectroscopy) dan IMVS (Intensity Modulated Photovoltage Spectroscopy). Pada artikel ini juga dilaporkan Impedansi antar lapisan DSSC melalui analisis EIS (Electrochemical Impedance Spectroscopy). DOI: http://dx.doi.org/10.17977/um024v4i12019p023

Abstract

Dye-sensitized solar cells (DSSC) made of TiO2 have received increasing attention since O’Regan and Gratzel published their work in Nature in 1991 [1]. Some studies have been conducted to determine the effect of the TiO2 electrode thickness on the DSSC performance. Nevertheless, the effect of the electrode thickness on the J–V characteristics, especially the short circuit current density (Jsc), has not been adequately addressed. Therefore, in this investigation, parametric analyses were conducted to study the DSSC electrode thickness effect on Jsc. Diffusion model was used to derive the equation of nanoporous semiconductor film thickness (d) dependence on Jsc. TiO2 paste was prepared using same method as Ref. [2]. The cells I-V curve were characterized using a computerized digital multi-meter (Keithley 2400) with a variable load. The cells short circuit current (Jsc) data gotten from the I-V characterization were plotted as the function of the thickness of TiO2 films. The result of the data plot was then compared and fitted with the theoretical modelling result. It is apparent that the DSSC performance largely depends on the TiO2 film thickness. The results was also showed that the diffusion model provided good approximation to describe the dependence of Jsc on the film thickness of DSSC.DOI: http://dx.doi.org/10.17977/um024v4i12019p001

Abstract

MnxFe3-xO4-Poly(m-ABS) nanocomposite has been successfully synthesized by in-situ polymerization. In the formation of MnxFe3-xO4-Poly(m-ABS) nanocomposites, FeCl synthesized from iron sand acts as an oxidant and m-aminobenzenesulfonic acid (m-ABS) as a monomer. Structural characterization has been successfully carried out using XRD, FTIR, and SEM. XRD test results show that the MnxFe3-xO4-Poly(m-ABS) nanocomposite has a particle size of about 10.62 nm. The appearance of peaks (111) and (620) with low intensity indicated the presence of poly(m-ABS). This low intensity was probably caused by the amorphous character of polyaniline and its derivatives. The FTIR results show the appearance of asymmetrical and symmetrical S=O strains, S-O, and C-S strains are the main characteristics of poly(m-ABS) which indicate the success of monomer polymerization. The results of the SEM test show that circular shapes dominate the particles with varying sizes with an average size of 42 nm. This result is different from the XRD results because SEM can only measure the surface of the particles, so the resulting size tends to be larger. Based on the study of the structure obtained shows that the MnxFe3-xO4-Poly(m-ABS) nanocomposite has the potential to be applied to energy conversion devices.DOI: 10.17977/um024v7i12022p016
