Materials Science: Making Flame Retardant

A Novel Non-Halogenated Flame Retardant for Composite Materials

Flame retardants, such as inorganic fillers or halogenated resins, are incorporated into composites either as additives or reactive materials. In order to improve processability and mechanical properties, as well as reduce smoke toxicity, a method is being developed to introduce highly effective, inexpensive flame retardant materials into thermoset resins. Superabsorbent polymers (SAP) can be l...

Application of Oligomers with Urea Linkage as Flame Retardant and Antibacterial Materials in Jute Fabric

A review of flame retardant polypropylene fibres

Flame retardants for polypropylene (PP) and their potential suitability for use in fibre applications are reviewed. Five principal types of generic flame retardant systems for inclusion in polypropylene fibres have been identified as phosphoruscontaining, halogen-containing, silicon-containing, metal hydrate and oxide and the more recently developed nanocomposite flame retardant formulations. T...

Addgene: Making Materials Sharing “Science As Usual”

Addgene (www.addgene.org) is a nonprofit organization that facilitates biomedical research and discovery by improving access to useful research materials and information. To fulfill this mission, Addgene works with hundreds of laboratories all over the world to collect high-quality published plasmids and data for the repository that can then be distributed to academic institutions and used to f...

Symptomatology during hypoxic exposure to flame-retardant chamber atmospheres.

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...
