This paper aims to synthesize and characterize an effective intumescent fire protective coating that incorporates eggshell powder as a novel biofiller. The performances of thermal stability, char formation, fire propagation, water resistance, and adhesion strength of coatings have been evaluated. A few intumescent flame-retardant coatings based on these three ecofriendly fire retardant additive...

Mixed micelles of (32)P-labeled phosphatidylcholine or phosphatidic acid (PA) and the nonionic detergent octylphenol polyethylene oxide (NP-40 Nonidet) were used to assay the activities of phospholipase D and PA phosphatase in crude extracts of mung bean (Vigna radiata) cotyledons. Together these enzymes degrade phosphatidylcholine to free choline, inorganic phosphate, and sn-1,2-diacylglycerol...

Sphingobium sp. strain TCM1 and Sphingomonas sp. strain TDK1 are haloalkyl phosphate flame retardant- and plasticizer-degrading bacteria. We report here the draft genome sequences of these strains to provide insights into the molecular mechanism underlying their degradation ability.

Flame-retardant and self-healing superhydrophobic coatings are fabricated on cotton fabric by a convenient solution-dipping method, which involves the sequential deposition of a trilayer of branched poly(ethylenimine) (bPEI), ammonium polyphosphate (APP), and fluorinated-decyl polyhedral oligomeric silsesquioxane (F-POSS). When directly exposed to flame, such a trilayer coating generates a poro...

A 150 News | Forum flame retardants exposure to tdCPP appears Widespread At a time of growing debate over the safety and usefulness of flame retardants added to consumer products, 1 new evidence is emerging about the breadth of human exposure to one of the most widely used of these compounds. Two new studies 2,3 document the presence of the flame retardant tris(1,3-dichloro-2-propyl) phosphate ...

BACKGROUND Flame retardant chemicals are used in materials on airplanes to slow the propagation of fire. These chemicals migrate from their source products and can be found in the dust of airplanes, creating the potential for exposure. METHODS To characterize exposure to flame retardant chemicals in airplane dust, we collected dust samples from locations inside 19 commercial airplanes parked ...
