Abstract:
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

Abstract:
Klebsiella oxytocaBAS-10 ferments citrate to acetic acid and CO2, and secretes a specific exopolysaccharide (EPS), which is able to bind different metallic species. These biomaterials may be used for different biotechnological purposes, including applications as innovative green biogenerated catalysts. In production of biogenerated Pd species, the Fe(III) as ferric citrate is added to anaerobic culture ofK. oxytocaBAS-10, in the presence of palladium species, to increase the EPS secretion and improve Pd-EPS yield. In this process, bi-metallic (FePd-EPS) biomaterials were produced for the first

Abstract:
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. In this paper, the BiOBr nanoplates with preferred growth orientation (102) facet and (110) facet were first synthesized using a hydrothermal method. 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. All samples were characterized using XRD, FE-SEM

Abstract:
Bi-metallic nanoparticles (NPs) have appeared to be more efficient as antimicrobials than mono-metallic NPs. The fungus Aspergillus terreus-mediated synthesis of bi-metallic Ag-Cu NPs was optimized using response surface methodology (RSM) to reach the maximum yield of NPs. The optimal conditions were validated using ANOVA. The optimal conditions were 1.5 mM total metal (Ag + Cu) concentration, 1.25 mg fungal biomass, 350 W microwave power, and 15 min reaction time. The structure and shape of the synthesized NPs (mostly 20–30 nm) were characterized using several analytical tools. The biological

Abstract:
In the last century the amino alcohol serinol (2-amino-1,3-propanediol) has become a common intermediate for several chemical processes. Since the 40's serinol was used as precursor for synthesis of antibiotics (e.g. chloramphenicol). In the last years, new scopes of application were discovered. Serinol is used as building block in the synthesis of X-ray contrast agents, pharmaceuticals (anti-inflammatory or analgesic drugs) or in the cosmetics industry. It can either be obtained by chemical processes based on 2-nitro-1,3-propanediol, dihydroxiacetone (1,3-Dihydroxypropan-2-one or simply DHA)

Abstract:
Well-defined silica supported bimetallic catalysts Pt100-x Pdx (where x is the molar ratio of Pd) are prepared by Surface Organometallic Chemistry (SOMC) via controlled decomposition of Pd2(allyl)2Cl2 on Pt/SiO2. For comparison purposes, Pt100-x Pdx bimetallic catalysts is also prepared by ion-exchange (IE). According to the results of STEM, XAS and H2 chemisorption, all bimetallic nanoparticles, prepared using neither SOMC nor IE, produce discrete formation of monometallic species (either Pt or Pd). Most catalysts exhibit a narrow particle size distribution with an average diameter ranging fr

Abstract:
One of the key challenges in nanoparticle synthesis is the quality control on scaling up the operation from bench to plant scale, which is constrained by conventionally adopted batch operation. Translation from batch operation to continuous green synthesis (metal, bi-metallic core-shell, and alloy nanoparticles (NPs)) with low polydispersity index (PDI) could unlock potential applications of metallic nanostructures with a projected market of $40.6 Billion and more by 20271. However, the continuous large-scale production suffers from high polydispersity due to lack of process optimization
