This research investigates the degradation and mechanical potential of Tamarindus Indiaca Fiber (TIF) reinforced into Poly Lactic Acid (PLA) resulting in a Wood Plastic Composite (WPC) that could be a potential alternative for prosthetic limbs. Fiber weight ratios at 10, 15, 20 and 25 wt%, were processed in micro and nano sizes individually through extrusion. Mechanical investigations were studied to analyze tensile, flexural, impact and hardness properties. Water Absorption Test (WAT) and Thermo Gravimetric Analysis (TGA) were performed for degradation studies. Field Emission Scanning Electron Microscope (FESEM) was used to study morphology. Nano TIF filled WPCs had superior properties than the micro TIF filled WPCs.

Since the ability of bacteria to acquire resistance is increasing, it is important to find alternative therapeutics. One possible way to deal with this problem is the use of nanoparticles as possible alternatives to antibiotic therapy. Silver nanoparticles (AgNPs) are viewed as a novel type of antibacterial agents. AgNPs can be synthesized using raw materials, such as red sand that found in nature. Characterization of the AgNPs was achieved using variety spectroscopic and microscopic devises. AgNPs showed antibacterial activity and large effect when combined with different antibiotics against Staphylococcus aureus, Acinetobacter baumannii, Escherichia coli, Salmonella typhimurium, Pseudomonas aeruginosa and Proteus vulgaris.

Malachite green dye has been known to have toxic carcinogenic characteristics and potential health risks for humans even at low concentrations. Hence, it is very vital to remediate the dye before discharge into water bodies or water treatment systems. Thus, this article demonstrated the removal of cleanup of malachite green (MG)dye from the aquatic phase using ZnO nanopowder. In this work batch adsorption experiments were accomplished as a function of contact time, pH, and initial dye concentration to study the efficiency of ZnO nanopowder on dye removal (MG). The obtained nanopowder was characterized using various techniques XRD, FTIR, SEM and EDX. The results shown that the maximum absorbed value was 233.16 mg / g. The findings show that ZnO nanopowder have fast contact time and initial concentration absorbing characteristics in dye removal. The maximum capacity of sorbent was found to be 246.36 mg. Furthermore, the study revealed that ZnO nanopowder is an effective sorbent for cleanup of malachite green dye in aqueous solution when comparing with other adsorbent materials. The Adsorption and kinetics parameters of the maximum capacity of sorbent and correlation coefficient showed that the data were well fitted the to the Langmuir isotherm R2 of 0.923 models and pseudo-second-order kinetic model with R2 of 0.994 respectively.

The simulation model for MCNP5 code was used to study the effect of the gold nanoparticle (AuNPs) in cancer breast samples. The dose rate distribution of AuNPs in water and breast phantom was calculated using MCNP5 code. For inhomogeneities, cone cells were designed to calculate dose distribution around Ir-192 source in breast and inhomogeneous medium that includes gold nanoparticles at different concentration. Both barometers, the track length energy deposition tally (F6) and pulse height tally (*F8), were used. The result indicated that the F6 is better than *F8 for radiation dose calculation. Angular doses distribution in water was compared with data published for tally F6 and*F8 with the different percentage range of 0.0136 to 0.3019% for tally F6 at the average angle of 5˚and 175˚respectively. For *F8 tally, different percentage range of - 0.0014 to 0.8253 % was obtained at an average angle of 75˚and 5˚ respectively. For breast phantom, the result of the F6 tally with the *F8 tally was compared. The difference in calculations between the two tallies in the angular anisotropic distribution was found to be in the range from 0.0514 to 0.4596% at the average angle of 15 ˚ and 175 ˚ respectively. The obtained results showed that the AuNP dose increases when the concentration increases up to ten percent (100 mg/ml), and then decreases for concentration higher than ten percent. The concentration of AuNPs greater than ten percent is not recommended. The results indicated that tally F6 is a good tool to calculate the effect of inhomogeneities due to breast cancer on brachytherapy.

Due to its toxicity, destruction of H2S gas has been an important topic of researchers. Many studies have been carried for investigating various techniques for the removal of this gas. One of those techniques is catalytic and photocatalytic destruction of H2S gas using various catalysts including TiO2 owing to its significant potential for degradation of various pollutants. This study investigates the destruction potential of Zr doped TiO2 for the abatement of H2S gas. The catalysts were characterized using different techniques like XRD, SEM, XRF. The catalytic experiments were performed using fixed bed catalyst system. The samples were analyzed using GC-MC technique and it was revealed that the Zr doping of TiO2 did not favour positively towards enhancing the H2S destruction potential as found in other studies.

An analysis of some properties of carbon nanotubes using X-ray diffraction analysis, Raman scattering, and IR luminescence is given. After doping with gadolinium the peak intensities in X-ray and Raman spectra drastically increase. It was found that 15% doping with gadolinium strongly affects the physical properties of carbon nanotubes functionalized by a carboxyl group.

We report the detailed temperature-dependent characteristics of Dy3+ doped SrAl2O4 phosphor. The phosphor synthesised using precipitation method was annealed at three different temperatures, specifically 800ºC, 900ºC, and 1000ºC. The three samples were analyzed using XRD, SEM, TEM, RAMAN, and FTIR. The observed photoluminescence emissions were consisting of peaks arising from the host SrAl2O4 as well as the dopant Dy3+. The crystallite sizes were found to be 27.22nm, 29.74nm, and 31.24nm, respectively, with the increase in annealing temperature. SEM, TEM images showed nearspherical, rod-like shapes of the crystals, and SAED confirmed the crystals were single-crystal. CIE analysis results showed that the colour coordinate was found to be very close to white colour in the three annealing temperatures, which is an advantage in the field of technology development.

The effect of γ-irradiation on the crosslinking process of nitrile butadiene rubber (NBR) with the participation of 4-dichloro 6-diethylamino-simmtriazine (DChDEAST) and 2,4- dimethylphenyl maleimide (DMPhM) was investigated. The molecular structure of the binary systems NBR + DChDEAST and NBR + DMPhM was determined by Fourier spectroscopy. Fourier transform infrared spectroscopy (FTIR) was used to determine the molecular structure of binary composite systems NBR + DChDEAST and NBR + DMPhM. The relative concentration of double bonds was predicted by determining its absorption by the optical density at the maximum absorption (967, 912 and 750 cm-1 ). It was found that at radiation doses above 250 kGy, the the number of crosslinks in irradiated blends were 1.05 × 104 and 0.66 × 104 mol /cm3 , respectively. The sensitizing effects of triasine and maleic compounds in radiation-chemical processes was investigated as well. Comprehensive studies of the structure and spatial network parameter of crosslinked NBR showed that the introduction of low molecular weight triazine and maleimide compounds increase the radiation-chemical yield (Gc) and this process also affect to increase the number of crosslinked molecules (1/Mnτ) and molecular weight of elastomers in turn.

The photo electronic devices based on surface plasmon resonance (SPR) phenomena have wide applications in the biomedical field. The biological environments to be detected are influenced by the SPR phenomenon, perhaps by the wavelength or the angle of incidence of resonance. In this work, the angular analysis of the phenomenon of double SPR in multilayer nanostructures is modeled by the transfer matrix method (T matrix). Consequently, we find that we can eliminate the error of simple SPR response and double SPR response based on the absolute deference response between the first SPR resonance and the second SPR double resonance.
