Abstract

Rare earth elements (REEs) from secondary resources need to be purified before being used as critical raw materials. A novel type of carbon nanotube (CNT)--based composite sorbent has been developed to adsorb REE metal ions from a low concentration of aqueous solution. The composite sorbents prepared from HEMA, CNC, and CNT were characterized by FTIR and their adsorption properties by ICP-OES. The results showed that the adsorption performance of sorbents depends on their constituting materials and the pH of the feeding solution. The presence of CNTs in the sorbents helps increase adsorption efficiency while increasing contact time. The highest adsorption efficiency (98%) was achieved at pH 4 with a contact time of 90 minutes. The prepared composite sorbents showed better adsorption selectivity for cerium (Ce3+) ions than neodymium (Nd3+) and lanthanum (La3+).

Abstract

Nickel-free stainless steel has emerged as an implant due to its excellent mechanical and corrosion properties. The toxic effect of Nickel ion released in the conventional SS316L need to be addressed. As one of austenitizing elements used as Nickel substitution, Nitrogen is an important alloying element to improve the strength and resistance to pitting susceptibility. In this research, the Nickel-free Fe-10Mn-16Cr-3Mo stainless steel has been developed. The effect of thermomechanical treatment consists of hot forging, hot rolling, cold rolling, and their combination followed by solution treatment on the electrochemical properties was further investigated. The corrosion resistance of Fe-10Mn-16Cr-3Mo was evaluated by the EIS and polarization test in Hank’s solution at 37℃. A ferrite-austenite duplex structure was identified by microstructural investigation, with indistinct intermetallic phase at homogenized sample. Meanwhile, fully recrystallized grains and twinning structures were formed at thermomechanical samples, indicating in dynamic recovery and dynamic recrystallization. Furthermore, the potentiodynamic parameters demonstrates the protective oxide in all samples. However, sample #5 shows a lower current density, around 0.184 µA/cm2, compared to other samples, indicating more protective passive film. In addition, the corrosion potential of sample #5, around 198 mV leading to higher corrosion resistance up to 0.02894 mmpy.

Abstract

Cu2O thin films have been deposited on indium-tin-oxide (ITO) coated glass substrate by electrochemical method or electrodeposition. The effect of deposition potential on the microstructure and optical properties of Cu2O thin films was studied. Electrodeposition for two Cu2O thin films was carried out at –0.5V and –0.6V relative to the standard calomel electrode (SCE) as a reference electrode. Cu2O thin films were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), and UV-Visible spectroscopy. The diffraction pattern indicated the cubic structure of the Cu2O crystal has been well grown. The lattice parameters of Cu2O films slightly increased as the potential of electrodeposition increased. The crystallite size of Cu2O films significantly increased as the applied potential increased. Cu2O thin films showed a smooth and flat surface morphology based on SEM images. The optical transmittance of the Cu2O thin films drastically decreased as the applied potential increased due to the film thickness increasing. The bandgap energy of Cu2O films based on the Tauc plot increased as the applied potential increased, that is 2.0 eV for the film deposited at -0.5V and 2.13 eV deposited at -0.6V.

Abstract

In this research, Nata de Cassava as the obtained bacterial cellulose was synthesized by Acetobacter xylinum using the liquid tapioca waste as the media. This research aimed to investigate the influence of concentration from carbon and nitrogen sources and then the type of bacteria used toward the obtained Nata de Cassava. The liquid tapioca waste was heated in a beaker glass at 70-80 °C and then added 5-10 % (w/v) of sugar and 0.1-0.5 % (w/v) of urea. The mixed solution was poured into a container and then cooled. Furthermore, 10-20 % (v/v) of Acetobacter xylinum was added and incubated at room temperature. After ten days, the Nata de cassava was harvested, sterilized, and immersed in ethanol, then dried in an oven at 60 °C. The results of FTIR, XRD and SEM analysis showed that Nata de Cassava had been successfully synthesized. The composition that produced the highest Nata de Cassava yield of 2.41% was the composition using 15% of A. xylinum, 10% of glucose and 0.1% of urea in the fermentation medium. In addition, the composition that produced the highest carbon conversion ratio of 26.15% was the composition that used 10% of A. xylinum, 5% of glucose and 0.2% of urea in the fermentation medium.

Abstract

We report sensing properties of functionalized single walled carbon nanotubes (f-SWCNTs) deposited on the flexible substrate of silicon (Si) and polyethylene tereptaphalate (PET). Deposition of f-SWCNT on Si rubber and PET surface was conducted by applying different manner of spray coating and dip coating techniques, respectively. Surface modification of f-SWCNT by ZnO nanostructure layer were applied by hydrothermal process.The research study were conducted to know the effect of substrate material and ZnO structure on the f-SWCNT surface which embedded in those flexible polymer substrates. The results reveal that f-SWCNT on Si substrate (f-SWCNT/Si) do not have a good response in gas sensing performance. In meanwhile f-SWCNT on PET substrates (f-SWCNT/PET) is more sensitive about 1.6% with 3s in response. ZnO structure layer modifying the surface structure of f-SWCNT enhance the sensitivity and responsiveness of the sensor with sensitivity of 4.1 % in 2s response after CO2 injection. Effect of bending treatment of the sensor and its stability were further investigated. Morphological surface of f-SWCNT network and crystal structure of ZnO and f-SWCNT were also observed by scanning electron microscope (SEM) and X-ray diffraction, respectively

Abstract

Paramagnetic Gd2O3 nanoparticles have been widely used as a contrast agent in bioimaging such as Magnetic Resonance Imaging (MRI). In this study, Gd2O3 nanoparticles were prepared using conventional and sonochemically precipitation methods, without any stabilizers. Gadolinium nitrate was used as a precursor and ammonium hydroxide as precipitating agent. The synthesized Gd2O3 nanoparticles were characterized using X-Ray Diffractometer (XRD), Particle Size Analyzer (PSA), Scanning Electron Microscope (SEM), and Vibrating Sample Magnetometer (VSM). It was found that Gd2O3 nanoparticles obtained in both methods have a cubic phase. The saturation magnetization (Ms) values of conventional and sonochemical samples were 1.63 emu/g and 1.44 emu/g respectively. The morphology of both samples shows agglomerated spherical shape in the nanometer range. The nanoparticles size of Gd2O3 that was confirmed by the Dynamic Light Scattering technique show samples from the sonochemical method has narrower size distribution (higher homogeneity) compare to samples from the conventional method. It was also found that the sonochemical synthesis technique is faster (time-saving), simple, convenient, and environmentally benign.

Abstract

COMPARATIVE LIFE CYCLE ASSESSMENT OF EDTA-MODIFIED AND AMINE GRAPTHED SILICA XEROGELS. NaI-131 removal from hospital wastewater using various silica xerogel adsorbents has been studied in order to meet the clearance level of radioactive waste. The contaminants emitted from the adsorbent manufacturing may affect the environment and human health. This study aimed to assess and minimize the environmental impacts of two adsorbents: EDTA-modified xerogel silica (EDTA Si-Xe) and Amine grafted silica xerogels (Amine Si-Xe), utilizing life cycle assessment (LCA) with the cradle to gate approach. OpenLCA 1.7 was used to estimate the impact, where background data were acquired from the European reference Life Cycle Database (ELCD) 3.2. The results show the dominant environmental impact resulting from adsorbent manufacturing is climate change. The impact of climate change on EDTA Si-Xe manufacturing and Amine Si-Xe manufacturing is about 0.510 CO2-eq and 0.258 CO2-eq, respectively. EDTA Si-Xe manufacturing performed the best (lower environmental impact) compare to Amine Si-Xe manufacturing. The process stage that contributes dominantly to environmental impact is calcination which gives high environmental impacts to climate change. The percent contribution of calcination to the environmental impact on EDTA Si-Xe manufacturing and Amine Si-Xe manufacturing is about 87% and 66%, respectively. The environmental impacts of the adsorbents manufacturing especially in climate change can be reduced by using Capture Carbon Storage (CCS) technology. Improvement analysis shows EDTA Si-Xe performed lower environmental impact compare to Amine Si-Xe with the value of impact categories lower than without applied CCS technology, especially value of climate change.

Abstract

APPLICATION OF RIETVELD ANALYSIS TO THE MULTIPHASE CRYSTAL STRUCTURE Bi1/2K1/2TiO3 USING MOLTEN SALT SYNTHESIS. Recently, an interesting application development of piezoelectric materials is as part of the tool for in-situ testing of nuclear fuel and the supporting materials in nuclear reactor, as well as sensors for safety systems in the reactor environment itself. One of the piezoelectric materials (lead free) is bismuth potassium titanate Bi1/2K1/2TiO3 (BKT) which is used in this research and has been successfully synthesized using the molten salt method. This method is a simple process that reacts to the base material in a solution of NaCl and KCl salts to produce nanocrystal ceramics powder with good compositional homogeneity and sinterability. The synthesis process has been carried out in two stages, first to produce Bi2Ti4O11 and then to add excess K2CO3 as a base material to produce BKT. The weight ratio between Bi2Ti4O11 and excess K2CO3 was 1:1.5 and 1:2. Structural identification of the synthesized results has been done by Rietveld analysis of the XRD pattern using PAN-Analytical Highscore software. The multiphase of BKT has been obtained by a predominantly tetragonal crystal system, in addition to cubic as second phase. This is indicated by the content of the tetragonal and cubic phases obtained at 64.5 and 36.5% for the ratio 1:1.5 and 80.3 % and 19.7 % for the ratio 1:2, respectively.The addition of excess K2CO3 increases, the content of the tetragonal BKT phase increases. . Besides that, the “a” lattice parameter increases and the “b” lattice parameter decreases, if the K2CO3 content is added. Likewise, the size of the crystallite and microstrain decreases with the in excess K2CO3.
