Biodegradable textiles made from cellulose, the most abundant biopolymer, have gained attention researchers, due to ease with which cellulose can be chemically modified introduce multifunctional groups, and because of its renewable biodegradable nature. One attractive features required for civilian military applications is flame-retardancy. This review focuses on various methods employed fabric...

Various morphologies of silica nanoparticles were synthesized by a microwave-assisted Pechini method. Silica nanostructures were synthesized via a fast reaction between tetra ethyl ortho silicate and ammonia at presence citric acid and other effective agents in Pechini procedure. Then for preparation of polymer-matrix nanocomposites, SiO2 nanoparticles were added to poly carbonate (PC) and poly...

Prolonged exposure to the flame retardants found in many household products and building materials is associated with adverse developmental, reproductive, and carcinogenic consequences. While these compounds have been studied in numerous epidemiological and animal models, less is known about the effects of flame retardant exposure on cell function. This study evaluated the toxicity of the commo...

This work reports the use of non-traditional fillers as flame retardants in polyester resin composites. Studies have been carried out to evaluate the fire-retardant properties of non-traditional fillers viz. hydroxyapatite, zinc borate and fly ash in combination with traditional fire retardant filler antimony trioxide, in prepolymer polyester resin composite system. Polyester resin was synthesi...

The standard problem of finding the optimal layout of structural material associated with maximum stiffness is expanded to include consideration of thermal criteria. The problem is posed as a three-phase layout problem where the phases include an insulating or fire retardant material and an unknown distribution of heat sources, in addition to the structural material. The model used is simple, y...

Hypoxia was studied in 12 men during 63-h exposures to 17 and 13% O2, with the subjects serving as their own controls by repeating the measurements in 21% O2. All test atmospheres were contaminated with 0.9% CO2 to simulate the condition of living aboard submarines. The mean SaO2's were 97-98% in all conditions of 21% O2, 96% in 17% O2 (n.s.), and 92% in 13% O2 (P less than 0.05). The blood con...
