Study of Film Formation From PS Latex/TiO2 NanocompositesEffect of Latex Size and TiO2 Content
(Wiley-Blackwell, 2014)
In this work we investigated the film formation from polystyrene (PS) latex/TiO2 nanocomposites using the steady state fluorescence (SSF) and UV-vis (UVV) techniques depending on PS particle size and TiO2 content. The ...
Gelation of PAAm-PVP composites: A fluorescence study
(World Scientific, 2014)
Hybrid hydrogels are a new class of composite materials. Polyacrylamide (PAAm) hydrogels are mainly produced by free radical crosslinking copolymerization (FCC) of AAm in the presence of N N'-methylene bis (acrylamide) ...
The WS(2)dependence on the elasticity and optical band gap energies of swollen PAAm composites
(Sage Publications, 2020)
New generation nano-filler polymer composites have many applications including biomedical, electronic and maritime related applications because of their mechanical, electronic and optical properties. The properties of ...
The modifier effects of chymotrypsin and trypsin enzymes on fluorescence lifetime distribution of "N-(1-pyrenyl)maleimide-bovine serum albumin" complex
(Pergamon-Elsevier Science LTD, 2016)
Chymotrypsin and trypsin are the well known proteolytic enzymes, both of which are synthesized in the pancreas as their precursors the inactive forms; chymotrypsinogen and trypsinogen and then are released into the duodenum ...
EFFECT OF CONTENT AND TEMPERATURE ON THE PHASE TRANSITIONS OF POLYMER COMPOSITES DOPED BY KAPPA CARRAGEENAN AND ALGINATE

Application of epidemic models to phase transitions
(Taylor & Francis Ltd, 2012)
The Susceptible-Infected-Recovered (SIR) and Susceptible-Exposed-Infected-Recovered (SEIR) models describe the spread of epidemics in a society. In the typical case, the ratio of the susceptible individuals fall from a ...
Sorption and Desorption of PVA-Pyrene Chains in and out of Agarose Gel
(Springer/Plenum Publishers, 2012)
In situ steady-state fluorescence (SSF) measurement technique was applied to investigation of pyrene labeled Poly(vinyl alcohol) (PVA-Py) molecules diffusion in and out of agarose gels. Gel samples with four different ...
GELATION MECHANISMS
(World Scientific Publ Co Pte Ltd, 2012)
In this paper, we survey the gelation mechanisms for various polymeric systems which are classified by the type and the strength of the cross-linkages. These are the "irreversible" gels that are cross-linked chemically by ...
Surfactant-free one-step fabrication of gelatin/PAAm/MWCNT composites for biomedical applications
(Springer, 2021)
Well-dispersed multiwalled carbon nanotube (MWCNT) and gelatin-enhanced polyacrylamide (PAAm) composites were synthesized via a free-radical copolymerization method. MWCNTs were added to the composite mixture in various ...
Mathematical models for phase transitions in biogels
(World Scientific Publ Co Pte Ltd, 2019)
It has been shown that reversible and irreversible phase transitions of biogels can be represented by epidemic models. The irreversible chemical sol-gel transitions are modeled by the Susceptible-Exposed-Infected-Removed ...
