Another theory of liquid-liquid explosion comes from Board et al. (1975). They noticed that when an initial disturbance, for example, at the vapor-liquid interface, causes a shock wave, some of the liquid is atomized, thus enhancing rapid heat transfer to the droplets. This action produces further expansion and atomization. When the droplets are heated to a temperature equal to the superheat temperature limit, rapid evaporation (flashing liquid) may cause an explosion. In fact, this theory resembles the theory of Reid (1979), except that only droplets, and not bulk liquid, have to be at the superheat temperature limit of atmospheric pressure (McDevitt et al. 1987).

When Midgley was sent to a Connecticut boarding school in 1905, he encountered the scientific tool that would help him make his most important discoveries. In his first chemistry class, the teacher cited the periodic table of the elements as evidence of God s existence. Midgley protested. As he described it, We argued. I contended that it simply indicated that the atoms were made up of still smaller particles. The argument went on for days and weeks. A useless argument Not in the least for in the course of it I had occasion to learn much about the periodic table and to have it impressed upon my memory as a very useful tool in research work. ...

In most other countries regulations or recommendations for a decrease of the radon daughter concentrations in homes have not been established. In USA and Canada limits have been given only for special cases, for example building on waste from uranium and phosphate industries (Atomic Energy Control Board, 1977 EPA, 1979 EPA, 1980). In Finland, there are general recommendations for homes (Finnish Radon Commission, 1982).

The graph of probability is close to the graph that accompanies this problem, except that the dart board is two-dimensional, while the atom is three-dimensional. This added dimension means that the volume close to the nucleus is relatively much smaller than is the area close to the center. The other difference, of course, is that it is harder for darts to get close to the center, while electrons are attracted to the nucleus. 

Fig. 4 The structures of a Fe2(4,4 -azpy)4(NCS)4 (EtOH) and b Fe(4,4 -azpy)2(NCS)2, viewed approximately down the 1-D channels. Framework atoms are represented as sticks and atoms of the ethanol guests as spheres. In Fe2(4,4 -azpy)4(NCS)4-(EtOH) the ethanol guests occupy every second 1-D channel in a "chess board" arrangement. Removal of ethanol by heating gives single crystals of Fe(4,4 -azpy)2(NCS)2, which has empty, equivalent 1-D channels and a concomitant quartering of the unit cell. Hydrogen atoms are omitted for clarity. Reprinted with permission from [39]. Copyright 2002 American Association for the Advancement of Science...

The PBDEs (decaBDE, octaBDE, and pentaBDE) and are used as flame retardants in plastics, electronic equipment, printed circuit boards, vehicles, furniture, textiles, carpets, and building materials. Global demand has increased rapidly since the 1970s with 70,000 tonnes produced in 2001. Their flame retardant activity relies on decomposition at high temperatures, leading to the release of bromine atoms. This slows the chemical reactions that drive 02-dependent fires. HBCDs are a flame retardant added to extruded and expanded polystyrene that is used as thermal insulation in buildings.
