Abstract The photocatalysis of Ag/Ni bi-metallic nano-particles on safranin O dye degradation was evaluated by UV light irradiations. Ag/Ni bi-metallic nanoparticles were synthesized by the green approach using Zingiber officinale root (Zinger) extract. The average particles size of Ag/Ni bi-metallic nanoparticles was found to be 70-88 nm from SEM image and from XRD patterns it was confirmed that the existence of Ag/Ni bi-metallic nano-particles. 8 mg of Ag/Ni bi-metallic nanoparticles present in 40 mL of 10 ppm dye, degraded completely in presence of UV light irradiations within 30 min time d

Abstract:

Last decades various imaging techniques have been applied in biological and biomedical research, such as magnetic resonance imaging, different types of tomography, fluorescence/bioluminescence, ultrasound, as well as multimodality approaches. Fluorescence imaging, especially in combination with nanoscale materials, is a very prospective tool for experiments in vivo and clinical applications due to its high temporal and spatial resolutions. Fluorescent nanoparticles (NPs), having ability to interact with biomolecules both on the surface of and inside the cells, may revolutionize the cell imagin

BiOBr with different preferred growth orientation facets would show a different photocatalytic performance. When decorated in situ with metallic Bi nanoparticles, Bi/BiOBr would commonly display an enhanced photocatalytic performance.

Then, some metallic Bi nanoparticles were modified in situ onto the (110)BiOBr nanoplates, which was expected to show a much more enhanced photocatalytic performance.

Abstract:

A report is presented about progress in the understanding of the properties of bi-metallic nanoparticles, their interaction with surfaces subsequent to low energy slowing down and the properties of nanostructured materials formed with these particles. A nanoparticle contains from a few atoms for the smallest ones to several thousand for the largest ones considered here. The properties of an atom result from quantization and the same is true for the molecules they form. The same is thus true for the smallest nanoparticles. At the other edge, many of the properties of macroscopic materials are w

Abstract:

Catalysis represents the cornerstone of chemistry, since catalytic processes are ubiquitous in almost all chemical processes developed for obtaining consumer goods. Nanocatalysis represents nowadays an innovative approach to obtain better properties for the catalysts: stable activity, good selectivity, easy to recover, and the possibility to be reused. Over the last few years, for the obtaining of new catalysts, classical methods—based on potential hazardous reagents—have been replaced with new methods emerged by replacing those reagents with plant extracts obtained in different conditions.

Abstract:

Bimetallic nanoparticles of silver (Ag) and gold (Au) were synthesized at room temperature using Curcumin. Reduction process of silver and gold ions with different molar ratios leads to production of different nanostructures including alloys and core-shells. Produced nanoparticles were characterized simultaneously with FTIR, UV/vis. spectroscopy, transmission electron microscopy (TEM), and Energy-dispersive X-ray (EDAX). UV/vis. optical absorption spectra of as synthesized nanoparticles reveals presence of surface palsmon resonance (SPR) of both silver at (425 nm) and gold at (540 nm) with sma

Abstract In this paper, mono-metallic catalysts, palladium (Pd) and gold (Au) and bi-metallic, Au-Pd supported on reduced graphene oxide (rGO) synthesized by Sol Immobilization technique. The as fabricated catalysts (Pd/rGO, Au/rGO and Au-Pd/rGO) have been tested by various techniques (Raman Spectroscopy, FE-SEM, XRD and TEM) to examine the structural, compositional and morphological characteristics. The performance of catalysts on the production of benzaldehyde via benzyl alcohol (BnOH) oxidation was investigated adopting H2O2 as an oxidizing agent. In general, Au-Pd/rGO catalyst presented a

Abstract:

Organotrialkoxysilanes like 3-aminopropyltrimethoxysilane (3-APTMS)-treated noble metal cations were rapidly converted into their respective nanoparticles in the presence of 3-glycidoxypropylytrimethoxysilane (3-GPTMS). The micellar activity of 3-APTMS also allowed us to replace 3-GPTMS with other suitable organic reagents (e.g., formaldehyde); this approach has significant advantages for preparing bimetallic and trimetallic analogs of noble metal nanoparticles that display efficient activity in many practical applications. The formation of monometallic gold, silver, and palladium nanoparticle

Abstract:

A Nd:YAG pulsed laser operating at the 10<sup>64</sup> nm wavelength, the 3 ns pulse duration, the 10<sup>10</sup> W/cm<sup>2</sup> intensity and the 10 Hz repetition rate is employed to irradiate biocompatible metallic targets based on Au, Bi and Ag placed in water. The laser-matter interaction produces nanometric spherical particles. The concentration of the solution with nanoparticles is controllable by the laser parameters, the ablative emission process, the irradiation time and the water’s volume. Generally, nanoparticles of about 10 nm in size and conc
