Nithish from Department of Electronics and Communication Engineering have won second and third prizes and were awarded cash prize of Rs 5000/- and Rs 3000/- respectively along with trophies. Avinash from the Department of Computer Science and Engineering and G. Monisha from the Department of Biomedical Engineering have won the first prize and awarded a cash prize of Rs 10000/- and trophy. Students from different streams of engineering exhibited their 45+ innovative projects to Judges and Visitors. VISTAS conducted their annual Intra-University Tech Expo “AVISHKAR 2022” on at their Shivalaya Auditorium, Pallavaram campus. Dynamic light scattering (DLS) is a non-destructive spectroscopic analysis technique that allows measuring corresponding to (i) light intensity scattered by the nanoparticles and (ii) size of. Arts & Science, Physiotherapy, Law and Pharmacy.School of Management Studies and Commerce.School of Hotel and Catering Management.Thus, a sufficient laser intensity should be chosen based on the light scattering characteristics of typical samples. The higher laser intensity was advantageous for measuring at high dilution more vigorously with varying laser intensities. The Lower Critical Solution Temperature, LCST phase transition of Poly(NIPAAM-PVP-PEGDA-DMAEMA) nanogel can be observed using the DLS technique. ![]() The study fulfills a vital knowledge gap by investigating the effects of laser intensity on the size of thermo-sensitive Poly(N-Isopropyl Acrylamide-Vinyl Pyrrolidone-Polyethylene Glycol Diacrylate-(2-(Dimethyl Amino)Ethyl Methacrylate)), Poly(NIPAAM-PVP-PEGDA-DMAEMA) nanogels and subsequent count rates in DLS measurements. Hence, in turn, it resulted in a miscalculation of the size of the nanogels by more than 100% of their expected values. d Diameter of the particle D Translational diffusion coefficient DLS Dynamic light scattering G(t) Autocorrelation function I(t0) Number of photons that. However, the scattering values were recently misled by an unexpected interaction between the incident light and thermo-sensitive nanogels. The diffusion coefficient, probed from the scattered light by supramolecules underexposure to incident light, allows the hydrodynamic radii to be calculated. ![]() DLS uses Brownian motion of nanoparticles (NPs) in a solvent in order to measure their size. Thermo-responsive polymer, lower critical solution temperature, dynamic light scattering, scattering intensity Abstractĭynamic light scattering (DLS) or photon cross-correlation spectroscopy (PCCS) is a very potent means for analyzing the diffusion behaviour of supramolecules in their solution form. Nanoparticle Size measurement using Dynamic Light Scattering. School of Chemical Engineering, College of Engineering, Universiti Teknologi MARA Cawangan Terengganu, Bukit Besi Campus, 23200 Dungun, Terengganu, Malaysia However, DLS has not been applied to complex systems such as biological cells because of its lack of molecular selectivity. Nanotechnology Laboratory, Radiation Processing Technology, Malaysian Nuclear Agency, Selangor, Malaysia Diffusion dynamics of polymers and colloidal dispersions at high concentrations have been widely studied using dynamic light scattering (DLS), a correlation spectroscopic method based on Rayleigh scattering.
