Measuring the size and complex refractive index of an aqueous aerosol particle using electromagnetic heating and cavity-enhanced Raman scattering

03-Jul-2018 | Aidan Rafferty; Thomas C. Preston, Physical Chemistry Chemical Physics, 2018

A quantitative understanding of light scattering by small homogeneous particles requires accurate knowledge of particle geometry and complex refractive index, m = n + ik. In weakly absorbing particles, k can be on the order of 10−9, which is well below the detection limit of almost all light ...

Scattering and Absorption Differ Drastically in Their Inner Filter Effects on Fluorescence, Resonance Synchronous, and Polarized Resonance Synchronous Spectroscopic Measurements

06-Jun-2018 | Joanna Xu; Buddhini C.N. Vithanage; Sumudu Athukorale; Dongmao Zhang, Analyst, 2018

Sample inner filter effect (IFE) induces spectral distortion and affects the linearity between intensity and analyte concentration in fluorescence, Raman, surface enhanced Raman, and Rayleigh light scattering measurements. Existing spectrofluorometeric-based measurements treat the light ...

Overcharging and reentrant condensation of thermoresponsive ionic microgels

30-May-2018 | Domenico Truzzolillo; Simona Sennato; Stefano Sarti; Stefano Casciardi; Chiara Bazzoni; Federico Bordi, Soft Matter, 2018

We investigated the complexation of thermoresponsive anionic poly(N-isopropylacrylamide) (PNiPAM) microgels and cationic ε-polylysine (ε-PLL) chains. By combining electrophoresis, light scattering, transmission electron microscopy (TEM) and dielectric spectroscopy (DS) we studied the adsorption ...

Formation of complexes in aqueous solutions of amphiphilic triblock polyelectrolytes of different topologies and an oppositely charged protein

30-May-2018 | Aristeidis Papagiannopoulos; Maria Karayianni; Stergios Pispas; Aurel Radulescu, Soft Matter, 2018

The complexation of lysozyme with aggregates from two triblock amphiphilic polyelectrolytes of the same blocks but different topologies and block molar masses, namely PS-b-SCPI-b-PEO and SCPI-b-PS-b-PEO, is investigated by scattering and spectroscopy methods. Light scattering reveals that the ...

Phase transition dynamics of single optically trapped aqueous potassium carbonate particles

24-May-2018 | Kıvanç Esat; Grégory David; Theodoros Poulkas; Mikhail Shein; Ruth Signorell, Physical Chemistry Chemical Physics, 2018

Fast dynamics (down to 10 ms) during exposure to changing relative humidity of single optically trapped K2CO3 particles were observed in the submicron to micron size range with time-resolved broadband light scattering and Raman spectroscopy. The study shows that complex multiple processes ...
