Agglomerates and Aggregates: Number and Size of Primary Particles from in-situ Mass-Mobility Measurements

, , , , , ,
Gas-borne nanoparticles generated at high temperatures undergo coagulation forming agglomerates (physically-bound particles) and aggregates (chemically- or sinter-bound particles). The structure of such particles influences their transport, light scattering, effective surface area and density. Real-time characterization [...]

Spectroscopic study on the charge redistribution between Au and Ag in Au@Ag core-shell nanoparticles

, , , , , ,
Charge transfer in heteromeric structures such as Au@Ag core-shell nanoparticles (NPs) and Au@Ag@Au double-shell NPs was demonstrated using X-ray absorption near-edge structure (XANES) and X-ray photoelectron spectroscopy (XPS) techniques. XANES analyses confirmed that the d-orbital [...]

Multi-Parametric Surface Plasmon Resonance – A new technique to determine thickness and refractive index of thin and thick layers

, , , , ,
Multi-Parametric(MP)-SPR empowers multidisciplinary research between life sciences and material sciences. Biochemists are moving from molecular-molecular interactions to molecule-material interactions, as seen in drug encapsulation or development of diagnostic kits. On the other hand, material science [...]

Characterizing Environmental Transformation of Multi-walled Carbon Nanotubes and Carbon Nano-Fiber Composites using Thermal Analysis and Related Hyphenated Techniques

, , , , , ,
Thermogravimetric analysis (TGA) coupled with gas chromatography and mass spectroscopy (TGA/GCMS), for the evolved gas analysis, has given insight to the stability and kinetics of structural changes and determining adsorbed organics to nanomaterials and nanocomposites. [...]
