Fluorous mixture synthesis minimizes the effort to synthesize small-molecule libraries by labelling the molecules rather than the reaction vessels. Reactants are labelled with fluorinated tags and products can later be demixed based on the fluorine content. A limit in the number of available tags can be overcome by using binary encoding so that a total of(More)
In a flash: pyrotechnic incendiary formulations with good stabilities toward various ignition stimuli have been developed without the need for barium or perchlorate oxidizers. KIO(4) and NaIO(4) were introduced as pyrotechnic oxidizers and exhibited excellent pyrotechnic performance. The periodate salts may garner widespread use in military and civilian(More)
Although there has been significant interest in the develop ment of environmentally friendly pyrotechnics, the develop ment of cost effective barium free green light emitting pyro technic formulations has remained elusive. Many barium compounds are human health hazards, and recent work by Steinhauser has shown that barium ores as raw materials may contain(More)
The examination of Laminac 4116/Lupersol and Epon 813/ Versamid 140 binder systems, and their influences on burn rates of pyrotechnic formulations is described. Laminac 4116/Luper sol based formulations had shorter burn times and larger heat of explosion values compared to their Epon 813/Versamid 140 counterparts. An understanding of the chemical structures(More)
[reaction: see text] In an effort to develop a more concise route to differentially substituted pyrroles (such as that found in the lamellarins), a completely regioselective one-pot double Suzuki coupling has been discovered. The key feature is the use of a ligand-free palladium catalyst under optimized conditions, which results only in coupling of the C5(More)
Prototype testing of perchlorate-free hand-held signal illuminants for the US Army's M126 A1 red-star and M195 green-star parachute illuminants are described. Although previous perchlorate-free variants for these items have been developed based on high-nitrogen compounds that are not readily available, the new formulations consist of anhydrous(More)
Smokes are used on the battlefield for signaling, for marking targets, and for screening troop movements. Many high-performance compositions are toxic or hazardous, while non-toxic alternatives offer sub-par performance. The environmentally benign compositions described herein use boron carbide as a pyrotechnic fuel to produce thick clouds of white smoke.(More)
The full-up prototype testing of perchlorate-free, hand-held, signal illuminants for the US Army's M126A1 red star parachute hand-held signal is described. Compared to the perchlorate-containing control, the disclosed illuminants yielded excellent stabilities toward various ignition stimuli while offering superior pyrotechnic performance. Militarily, the(More)
The development of perchlorate-free M662 40 mm illuminating pyrotechnic compositions is described. On the bases of cost, performance, and sensitivity, potassium periodate was determined to be most effective potassium perchlorate replacement in the compositions tested. The optimal periodate-based composition exceeded the performance of the(More)
