Disordered Cellulose-based Nanostructures for Enhanced Light-scattering [PDF]

open access: yes, 2017
Cellulose is the most abundant bio-polymer on earth. Cellulose fibres, such as the one extracted form cotton or woodpulp, have been used by humankind for hundreds of years to make textiles and paper.

Investigation of Factors Influencing Formation of Nanoemulsion by Spontaneous Emulsification: Impact on Droplet Size, Polydispersity Index, and Stability

open access: yesBioengineering, 2022
Interest in nanoemulsion technology has increased steadily in recent years for its widespread applications in the delivery of pharmaceuticals, nutraceuticals, and cosmeceuticals. Rational selection of the composition and the preparation method is crucial for developing a stable nanoemulsion system with desired physicochemical characteristics.

Application of ensemble machine learning approach to assess the factors affecting size and polydispersity index of liposomal nanoparticles

open access: yesScientific Reports, 2023
AbstractLiposome nanoparticles have emerged as promising drug delivery systems due to their unique properties. Assessing particle size and polydispersity index (PDI) is critical for evaluating the quality of these liposomal nanoparticles. However, optimizing these parameters in a laboratory setting is both costly and time-consuming. This study aimed to

Diffusion and viscosity in a supercooled polydisperse system [PDF]

open access: yes, 2002
We have carried out extensive molecular dynamics simulations of a supercooled polydisperse Lennard-Jones liquid with large variations in temperature at a fixed pressure. The particles in the system are considered to be polydisperse both in size and mass.

Intermediate Radical Termination Theory in Elucidation of RAFT Kinetics and Comparison to Experimental Data [PDF]

open access: yesعلوم و تکنولوژی پلیمر, 2008
In current work a comprehensive mechanism based on intermediate radical termination theory is assumed for RAFT polymerization of styrene over cumyl dithiobenzoate as RAFT agent. Rate constants for addition (ka) and fragmentation reactions (kf) are set to

Physicochemical characteristics of liposome encapsulation of stingless bees' propolis

open access: yesHeliyon, 2021
Nutraceuticals from natural sources have shown potential new leads in functional food products. Despite a broad range of health-promoting effects, these compounds are easily oxidized and unstable, making their utilization as nutraceutical ingredients ...

Effects of polydispersity on the glass transition dynamics of aqueous suspensions of soft spherical colloidal particles

open access: yes, 2017
Thermoresponsive poly(N-isopropylacrylamide) (PNIPAM) particles of a nearly constant swelling ratio and with polydispersity indices (PDIs) varying over a wide range (7.4% - 48.9%) are synthesized to study the effects of polydispersity on the dynamics of ...

An external potential dynamic study on the formation of interface in polydisperse polymer blends

open access: yes, 2009
The formation of interface from an initial sharp interface in polydisperse A/B blends is studied using the external potential dynamic method. The present model is a nonlocal coupling model as we take into account the correlation between segments in a ...
