Solid H2
(Preview)
Title: A snowflake's chance in heaven Authors: Mark A. Walker We consider the survival of solid H2 in the diffuse interstellar medium, with application to grains which are small enough to qualify as dust. Consideration of only the thermal aspects of this problem leads to the familiar conclusion th...

Nanoparticle Crystals
(Preview)
Crystals melt when they're cooled Growing thin films out of nanoparticles in ordered, crystalline sheets, to make anything from microelectronic components to solar cells, would be a boon for materials researchers, but the physics is tricky because particles of that size don't form crystals the...

Rare earth element
(Preview)
As defined by IUPAC, rare earth elements or rare earth metals are a collection of seventeen chemical elements in the periodic table, namely scandium, yttrium, and the fifteen lanthanides. Scandium and yttrium are considered rare earth elements since they tend to occur in the same ore deposits as t...

zinc dicyanoaurate
(Preview)
The atomic structure of a zinc-based material has a surprising amount in common with the tentacles of an octopus, Oxford University researchers have found. When pressure is applied all around them most materials shrink. But materials exhibiting a rare property known as negative linear compress...

Roentgenium
(Preview)
Roentgenium is a synthetic radioactive chemical element with the symbol Rg and atomic number 111. It is placed as the heaviest member of the group 11 (IB) elements, although a sufficiently stable isotope has not yet been produced in a sufficient amount that would confirm this position as a heavier h...

Fipel technology
(Preview)
Plastic bulb development promises better quality light US researchers say they have developed a new type of lighting that could replace fluorescent bulbs. The new source is made from layers of plastic and is said to be more efficient while producing a better quality of flicker-free light. [url=ht...

Iodine
(Preview)
Iodine was discovered by Bernard Courtois in 1811. Courtois gave samples to his friends, Charles Bernard Desormes (1777-1862) and Nicolas Clément (1779-1841), to continue research. He also gave some of the substance to chemist Joseph Louis Gay-Lussac (1778-1850), and to physicist André-Mari...

Curium
(Preview)
Curium is a synthetic chemical element with the symbol Cm and atomic number 96. This radioactive transuranic element of the actinide series was named after Marie Skodowska-Curie and her husband Pierre Curie. Curium was first intentionally produced and identified in summer 1944 by the group of Gl...

Darmstadtium
(Preview)
Darmstadtium is a chemical element with the symbol Ds and atomic number 110. It is placed as the heaviest member of group 10 but a sufficiently stable isotope is not known which would allow chemical experiments to confirm its place. This synthetic element is one of the so-called super-heavy atoms an...
