Corn Oil-Based Highly Flame Retardant Rigid Polyurethane Foams For Industrial Application, Muhammad Rizwan Sulaiman
Corn Oil-Based Highly Flame Retardant Rigid Polyurethane Foams For Industrial Application, Muhammad Rizwan Sulaiman
Electronic Theses & Dissertations
The synthesis of flame retardant polyurethane (PU) foam was carried out using two different flame retardants, such as triethyl phosphate (TEP) and triphenyl phosphate (TPP). The thermal and mechanical characteristics of the foam were analyzed. The obtained TGA results confirmed that the flame retardant acts in the gaseous form to stop the fire. All the prepared samples displayed excellent closed cell content, which was above 90 %. The burning time were reduced from 80 s to 7.5 s with the weight loss 3.2% of for sample E-12 (19.29 % TEP) and from 80 s to 11 s with the weight …
Targeted Combination Therapy Of Nsclc Using Taxol And Fingolimod Loaded Nanoceria, Raghunath Narayanam
Targeted Combination Therapy Of Nsclc Using Taxol And Fingolimod Loaded Nanoceria, Raghunath Narayanam

Among various types of cancers, lung cancer reports highest death rate and Non-Small cell lung cancer causes highest mortality in lung cancers. This is mainly due to the scarcity of treatment options and the available treatment shows numerous adverse effects. In the recent times, nanotechnology paved a new path for the diagnosis and therapy of cancer. In this study, we worked on a novel, multifunctional nanoceria (NC) platform loaded with two unique drugs taxol and fingolimod, which acts in their own ways providing synergic therapeutic effect. We hypothesized that the usage of the polyacrylic acid (PAA) coated nanoceria (PNC) increases …
Environment-Friendly Flame Retardants For Bio-Based Polyurethanes, Felipe Martins De Souza
Environment-Friendly Flame Retardants For Bio-Based Polyurethanes, Felipe Martins De Souza
Electronic Theses & Dissertations
Finding alternative ways to decrease the large consumption of non-renewable resources has been one of the greatest challenges faced by the industry and academia. The trend of using bio-renewable-based materials is an interesting alternative to tackle environmental issues as well as provide economically viable materials. In this work, carvone, an essential oil, was used to synthesize a bio-based polyol through a thiol-ene reaction. The chemical functions were analyzed through Fourier transformed infrared spectrum (FTIR), gel permeation chromatography (GPC), viscosity, and hydroxyl number, which confirmed the synthesis of carvone-based polyol. The latter was then physically blended with three different flame-retardants separately: …
