One of the most effective removals is iron oxide nanoparticles. In recent years many studies have been carried out for modifying the surface of the nanoparticles and increasing its effectiveness and efficiency. Materials and Methods: In this paper coated iron oxide nanoparticles were prepared using Polylophium involucratum extract. To examine the structure of the absorbent the infrared spectrometer instrument and SEM were used to check the size of nanoparticles. the average size of them were determined 60 nm. Results: The synthesized coated nanoparticles were used to eliminate lead and cadmium after optimization conditions (pH of 6, absorbent weight of 20 mg, and time of 4 minutes) in water samples. Magnetic green coated nanoparticles have many advantages such as non-toxicity, biocompatibility, shorter extraction time, avoiding the use of organic solvents, low cost, ease of use, high accuracy, recovery and adsorption capacity due to the nanostructure and high ratio of surface to volume. Conclusion: Functionalized nanoparticles by extract of the plant is able to link up with heavy metal ions and increase the efficiency of the nanoparticles in the removal of these two heavy metals.

Even though some of this husk is converted into end products such as feedstock and adsorbent most is burnt openly, causing environmental and health problems especially in poor and developing countries. Therefore, it is very important to find pathways to fully utilize the rice husk. Material and Methodology: In this study, the fabrication and characterization of ZSM-12 zeolite using rice husk ash as an alternative cheap silica source, and synthesis and characterization of magnesium oxide nanoparticles in ZSM-12 matrix by solid state reaction and ion exchange methods is reported. Disk diffusion method and MIC were used to evaluate the antimicrobial activity of nanoparticles on gram-negative (Escherichia coli) and gram-positive (Staphylococcus aureus) strains of bacteria compared to standard commercial antibiotic disks. Findings: Synthesized samples were evaluated using X-ray diffraction, scanning electron microscopy, energy dispersive X-Ray spectroscopy and transmission electron microscopy. XRD results revealed diffraction peaks for each of the two compounds in the MgO/ZSM-12 nanocomposite. Discussion and Conclusion: Transmission electron microscopy image of nanocomposite indicated that nanoparticles size of MgO is ~ 35 nm. Nanocomposite exhibited antibacterial activity with minimal inhibitory concentration of 96 µg/mL against E. coli and S. aureus. Manuscript profile -

Method: In this study to analyze green chemistry technology invention, after extracting the appropriate search term, search by "keyword" in the abstract, title, and claim (s) of patent was done. To this end, those inventions related to green chemistry technology which have been registered within the 1993 to 2013 in different countries or organizations were evaluated using QPAT patent database. Findings: Patents in the field of green chemistry are mainly originated from activities of factories and companies. In general, chemical and electronic sectors hold the most patents. Japan is the largest inventor region with 32% of all green chemistry patents. China is the second largest region, holding 29% of patents, followed by the United States (24%), Europe (14 %) and the rest of the world (1%). Conclusion: The economic incentives, legal and regulatory pressures and avoidance from charges by governments, citizens and environmental organizations were the major factors to move towards innovation in cleaner technologies and more favorable technological applications. The use of green chemistry technologies has proven to be an intelligent business strategy that can provide both environmental and economic benefits and can induce further technology diffusion. The results of this study provide helpful information for developing R&D strategies, policies, planning and management of environmental issues. The obtained results can be used to build a technology strategy in a private company and to make policy at a public level. Manuscript profile -

In this study, FeNi3 / SiO2 / PPA nanoparticles were synthesized as solid acid support for the synthesis of multicomponent reaction of tetrahydrobenzo[a]xanthene-11-ones in solvent-free conditions. The reaction of tetrahydrobenzo[a]xanthene-11-ones with 1gr of the catalyst was achieved in high yield products at 120 ° C without solvent and temperature. FeNi3 / SiO2 / PPA nanoparticles were confirmed by IR, TEM, SEM and EDX spectroscopy. The results showed that the catalyst has high activity, environmentally friendly, heterogeneous and can be easily recovered from the reaction mixture without losing its catalytic activity.

The aim of this study is to synthesize Ce2Sn2O7 NPs, to investigate their performance on the three-component and efficient reaction of 3,4-dihydropyrimidine (2H) of it. Analysis of the structure and morphology of nanoparticles was done by EDX, TEM, SEM, FT-IR analysis and the effect of various parameters such as solvent, temperature, time, amount of catalyst and substrate on the process of reactions was investigated. The results showed that the reaction of 3,4-dihydropyrimidine (2H) in the presence of 5 mg Ce2Sn2O7 catalyst at a temperature of 70 ℃ for half an hour had 92% efficiency in solvent-free conditions and the best efficiency in the presence of ethanol solvent. Ce2Sn2O7 nanocatalyst was separated by a magnet. After 10 uses, their performance decreased slightly. The nanoparticles used have outstanding properties such as thermal stability, high mechanical properties, good active sites, and a very large contact surface, allowing them to be used in several reactions.

In this study preparation of bissulfamic acid-grafted on silica-coated nano-Fe3O4 particles (MNPs-TBSA), and their application as a retrievable heterogeneous acidic catalyst for the green synthesis of 1,4-Dihydropyridines and 2,3-dihydroquinazolines is probed. This nanocatalyst is easily separated from the reaction mixture with the assistance of an external magnetic field and reuse for several runs without deterioration in catalytic activity. The morphology, structure, and size of magnetic nanoparticles were characterized via SEM, XRD, EDS, FT-IR and TGA/DTA. Eco-friendly and non-toxic condition, high yield and purity of the desired products, short reaction time along with the ease of the workup procedure outline the advantages of these new methodologies over the earlier ones.
