Anodizing method carried out by preparing an electrochemical system consisting of a titanium plate as anode and Pt wire as cathode in electrolyte containing glycerol, ammonium fluoride and water. Voltage applied from the DC current source and followed by thermal treatment at a temperature of 500oC. The photoelectrode further characterized by using X-Ray Diffraction and Surface Area Analyzer. The result of anti-corrosion test of stainless steel 304 by TiO2-NT showed that photopotential value of steel shifted to the more negative value in UV light. The significant potential shift occurs at pH 8 and the corrosion rate of stainless steel 304 couple with TiO2-NT decrease reaches 1.7 times. It concluded that the photoelectrodes can be used to reduce the corrosion rate of stainless steel 304 by utilizing sollar energy as a source of UV light.

Synthesis of MCM-48 and its modification by NH2 conducted by Ryoo methods where is the salt of Ludox HS40 solution mixed with NaOH solution then heated, followed by making mixture of CTAB and Triton X-100. The resulting gel mixture is heated at temperature of 100 °C for 24 hours. The reaction mixture added 30% acetic acid until pH 10. Then the mixture was heated at 100 °C for 24 hours then cooled at room temperature. MCM-48 mesoporous silica that has formed was filtered, washed with distilled water and dried at 120 °C. MCM-48 mesoporous silica characterized using XRD and FTIR. Modification of MCM-48-NH2 was done by adding 3-APTES into mesoporous silica. XRD analysis results showed that the characteristic peaks at 2 theta 2.4o have Miller indices 211and several peaks with low intensity. These peaks are typical peak for MCM-48. By FTIR showed the specific areas observed for organic molecules (surfactant) in MCM-48 synthesized; CH span (2800-3100 cm-1) and CH bending (1400 to 1500 cm-1). C-H bending vibration was observed in 1645; 1512 and 1481 cm-1. The success of modified MCM-48-NH2 was shown by the appearance of two absorption bands at wave numbers 3368 and 3424 cm-1 which indicate the presence of a primary amine or an amino group (-NH2) in the mesoporous channel

Abstract

Silver nanoparticles have been synthesized by the reduction method using salam leaf extract (Syzygium polyanthum) as a reducing agent. The silver nanoparticles produced were then tested for their activity as antioxidants. The formation of silver nanoparticles was carried out by adding the leaf extract into the solution of AgNO3 and homogenized using a magnetic stirrer. A UV-Vis spectrophotometer was used to confirm the formation of silver nanoparticles. Particle Size Analyzer (PSA), Scanning Electron Microscope (SEM), X-Ray Diffractometer (XRD) and Fourir Transform Infra Red (FTIR) spectrometers were used to characterize the nanoparticles produced before being tested for antioxidant activity. The results showed that the absorbance value increased with increasing reaction contact time. The maximum uptake was obtained at wavelengths of 432-446 nm using a UV-Vis spectrophotometer. The particle size was determined using a PSA with an average particle size distribution of 45.7 nm. The average diameter of silver nanoparticles was 10.06 – 13.97 nm and the silver nanoparticles had rod-shapes. Functional groups that play a role in the synthesis of nanoparticles were –OH, –C=O, and –C-O groups. Silver nanoparticles inhibited free radicals as antioxidants with the IC50 value of 582.7 ppm.

Abstract

Mesoporous silica with cubic structure (MCM-48) was synthesized using Ludox HS40 as silica source and cetyltrimethylammonium bromide (CTAB) as a template. MCM-48 was used to adsorb the antibiotic of tetracycline hydrochloride. An X-ray diffractometer observed the x-ray diffraction pattern of MCM-48 and functional groups observed by a Fourier Transformed Infrared (FTIR) spectrometer. Parameters used to study adsorption were contact time and concentration. The pseudo-second-order was the kinetic order that fitted well with the adsorption of tetracycline HCl. The adsorption of tetracycline HCl on MCM-48 followed the Freundlich isotherm with the adsorption capacity of 0.98 mg/g.

Abstract

The adsorption of Bismarck Brown R (BBR) dye has been conducted using mesoporous silica (MCM-48). We synthesized the adsorbent using Ludox HS-40 as a silica source and surfactants of Cetyl Trimethylammonium Bromide (CTAB) and Triton X-100. The characterization of MCM-48 was performed using Fourier transform infrared (FTIR), X-ray diffraction (XRD), and scanning electron microscopy (SEM). Various contact times were used to study the adsorption kinetics, and concentrations were used to study the adsorption isotherm. The optimum contact time of Bismarck Brown R dye was 120 minutes, and the adsorption followed a pseudo-second-order model. Based on the equation Langmuir and Freundlich adsorption isotherms, the adsorption capacity values of each are obtained 158.7301 mg g-1 and 4.3601 mg g-1. Our results showed that the material can be used as a new dye adsorbent.

Abstract

The mineral feldspar is a potential raw material in zeolite synthesis because of the high content of SiO2 and Al2O3. Characterization of X-ray diffraction (XRD) and X-ray fluorescence (XRF) on Mesawa feldspar minerals showed high crystallinity and aluminosilicate composition. The synthesis process uses the hydrothermal method with various times and concentrations of NaOH. The sample was mixed with NaOH, stirred until homogeneous at 300 rpm for 1 hour, and transferred to an autoclave. The autoclave was tightly closed and heated in an oven at 170 °C for 72 hours. XRD and XRF analysis revealed that the feldspar mineral had changed to sodalite with a purity of 90.89% and 90.06%; with a yield of 80.89% and 87.36%. FTIR characteristics show a specific peak for sodalite at 422-460 cm-1 related to Si-O bond vibrations, and absorption bands at 698 and 719 cm-1 related to Al-OH vibrations. The SEM results confirmed the morphology of the sodalite resembling balls like raspberries". This research proves that the Mesawa feldspar mineral sample contains type 6 secondary building units, the same blocks as zeolite analcime and cancrinite, so it has the potential as an adsorbent for heavy metals and as a catalyst alternative

Abstract

The potential uses of ecologically benign nickel nanoparticle manufacturing in various sectors, such as biomedicine, energy storage, and catalysis, have garnered much interest. This paper covers green approaches to nickel nanoparticle manufacturing, which integrate natural substances as stabilizing and reducing agents with eco-friendly processes. Phytochemicals derived from bacteria, microorganisms, and plant leaf extracts can convert nickel ions (Ni2+) into nickel nanoparticles. Room temperature is used for the synthesis procedure, and neither dangerous compounds nor unusual reaction conditions are used. Using a variety of analytical methods, the resultant nickel nanoparticles were characterized. We also investigate the possibility of using the generated nickel nanoparticles as a cytotoxic, photocatalytic, antioxidant, and antibacterial agents. The antimicrobial activity of nickel nanoparticles demonstrates their potent antibacterial properties, while their antioxidant activity demonstrates their capacity to combat free radicals effectively. Furthermore, nickel nanoparticles' cytotoxic activity demonstrates their capacity to kill cancer cells, and their photocatalytic activity demonstrates their efficiency in breaking down organic contaminants. This review highlights the value of ecologically benign synthetic methods and creates new avenues for developing nickel nanoparticle applications in health and the environment.
