This article describes the synthesis of a new bio-based organocatalytic surfactant. The nine steps were optimized, fully respecting principles green chemistry. surfactant aspect was then evaluated with use tensiometric studies. molecular organization in vesicles an aqueous medium characterized by Dynamic Light Scattering (DLS) and confirmed using Density Functional Theory (DFT) modelling.

Manganese zinc ferrite nanoparticles (MZF NPs) were synthesized by using a direct, efficient and environmental friendly hydrothermal method. To improve the colloidal stability of MZF NPs for biomedical applications, NPs were coated with chitosan by ionic gelation technique using sodium tripolyphosphate (TPP) as crosslinker. The synthesized NPs were characterized by X ray diffraction (XRD) analy...

A straightforward procedure to synthesize keratin nanoparticles (KNP) from chicken feathers was introduced. The characterization of the synthesized nanoparticles was done using Fourier transform infrared (FTIR) spectroscopy, dynamic light scattering (DLS), X-ray diffraction (XRD) patterns and transmission electron microscopy (TEM). The FTIR analysis revealed no significant chemical change after...

in the present study, a simple, fast and eco-friendly biosynthesis of silver nanoparticles (agnps) using   mentha langifolia leaf extract as the reducing agent was investigated. nanoparticles forming were indicated by the color changes in solution and were confirmed by uv-vis spectrum, ft-ir analysis and scanning electron microscopic (sem) micrograph. the average particle size of produced agnps...

The synthesis of nanoparticles silica oxide from rice husk, sugar cane bagasse and coffee husk, by employing vermicompost with annelids (Eisenia foetida) is reported. The product (humus) is calcinated and extracted to recover the crystalline nanoparticles. X-ray diffraction (XRD), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM) and dynamic light ...

There are two types of light scattering measurements: static light scattering (SLS) and dynamic light scattering (DLS). The SLS method is used to estimate the molecular weight (MW) of particles by measuring the time-averaged intensity of light scattered by the particles, whereas the DLS method is used to estimate the diffusion coefficient of particles by observing the time-correlation of scatte...

Few methods exist that can accurately handle dynamic light scattering in the regime between single and highly multiple scattering. We demonstrate dynamic light scattering Monte Carlo (DLS-MC), a numerical method by which the electric field autocorrelation function may be calculated for arbitrary geometries if the optical properties and particle motion are known or assumed. DLS-MC requires no as...

A facile and sensitive immunoassay protocol for the detection of alpha-fetoprotein (AFP) was developed using gold-coated iron oxide magnetic nanoclusters and dynamic light scattering (DLS) methods. The increase in the average particle size due to AFP-mediated aggregation was measured using DLS, and the detection limit was better than 0.01 ng mL(-1).

Silver nano-colloids have been generated via Laser Ablation Synthesis in Solution (LASiS) system. Nanoparticle formation with particle size below 50 nm DI water was confirmed using UV-VIS spectroscopy, Dynamic Light Scattering (DLS) technique, and transmission electron microscopy (TEM). Supercapacitor structure, having dimension 11 mm x 10 mm, successfully Aerosol Jet printed on an untreated po...
