“…The identification of the functional groups in the synthesized magnetic nanoparticles can be obtained by Fourier-transform infrared spectroscopy (FTIR) technique. The absorption spectra of the nanoparticles were determined using ultraviolet-visible (UV-VIS) spectroscopy [141,142]. Zeta potential measurement is used for the determination of the surface charge of nanoparticles.…”

Research on contamination of groundwater and drinking water is of major importance. Due to the rapid and significant progress in the last decade in nanotechnology and its potential applications to water purification, such as adsorption of heavy metal ion from contaminated water, a wide number of articles have been published. An evaluating frame of the main findings of recent research on heavy metal removal using magnetic nanoparticles, with emphasis on water quality and method applicability, is presented. A large number of articles have been studied with a focus on the synthesis and characterization procedures for bare and modified magnetic nanoparticles as well as on their adsorption capacity and the corresponding desorption process of the methods are presented. The present review analysis shows that the experimental procedures demonstrate high adsorption capacity for pollutants from aquatic solutions. Moreover, reuse of the employed nanoparticles up to five times leads to an efficiency up to 90%. We must mention also that in some rare occasions, nanoparticles have been reused up to 22 times.

“…Tan et al 32 successfully synthesized NiNPs by pulse laser ablation in distilled water using laser wavelengths of 1064 and 532 nm. Experimentally it was found that the absorption peak intensities of the NiNPs increased at higher laser pulse energy and higher absorption peak was observed for the shorter laser wavelength of 532 nm compared to 1064 nm.…”

Optimization of epoxidation by using response surface methodology (RSM) based on three-level three-factorial central composite design (CCD) was used. Response percentage of relative oxirane content (%RCO) was studied to determine the optimum reaction condition for production of polyols. The predicted value of model (85 %) was excellent in accordance to experimental value (81 %). All parameters (temperature, molar ratio of formic acid to oleic acid and molar ratio of hydrogen peroxide to oleic acid) were significant in influencing the course of epoxidation reaction (p < 0.05). The interaction between all parameters is also highly significant with p < 0.0001. Optimum reaction conditions obtained from RSM were as follows: the temperature 318 K, molar ratio of formic acid to oleic acid 1.64:1 and molar ratio of hydrogen peroxide to oleic acid 2:1. The epoxidation of palm oleic acid was carried out by using in situ performic acid. FTIR analysis showed the formation of epoxy functional groups at optimum reaction condition at the wavelength of 1340 cm-1. This epoxide group was used to produce polyols by using hydroxylation process and the polyols functional group was detected at the wavelength of 816 cm-1

Surface plasmon resonance (SPR) and localized surface plasmon resonance (LSPR) are among the most common and powerful label-free refractive index-based biosensing techniques available nowadays. Focusing on LSPR sensors, their performance is highly dependent on the size, shape, and nature of the nanomaterial employed. Indeed, the tailoring of those parameters allows the development of LSPR sensors with a tunable wavelength range between the ultra-violet (UV) and near infra-red (NIR). Furthermore, dealing with LSPR along optical fiber technology, with their low attenuation coefficients at NIR, allow for the possibility to create ultra-sensitive and long-range sensing networks to be deployed in a variety of both biological and chemical sensors. This work provides a detailed review of the key science underpinning such systems as well as recent progress in the development of several LSPR-based biosensors in the NIR wavelengths, including an overview of the LSPR phenomena along recent developments in the field of nanomaterials and nanostructure development towards NIR sensing. The review ends with a consideration of key advances in terms of nanostructure characteristics for LSPR sensing and prospects for future research and advances in this field.
