The authors report the low temperature specific heat Cp and magnetic measurements for solid solution Al-3at.percent Mn, Al86Mn14 and Al25Mn20Si5 in quasi-crystalline phases. From the amplitude of the electronic specific heat determined below 0.3K, they pro ...
The crystal and molecular structure of dinitrato(1,7,10,16‐tetraoxa‐4,13‐diazacyclooctadecane)europium(III) nitrate, ([Eu(NO3)2(C12H26N2O4)]NO3) has been determined from single‐crystal X‐ ray diffraction: a = 12.567(3), b = 11.585(3), c = 16.354(5) Å, β = ...
Low temperature specific heat and ac susceptibility studies on quasicrystalline Al//8//6Mn//1//4 and Al//7//5Mn//2//0Si//5 show that most Mn's are nonmagnetic. The fraction of magnetic Mn's (about 5-10% of all Mn atoms) exhibit spin-glass behavior which in ...
The structures of the cubic, the tetragonal and the orthorhombic phases of single crystals of the ferroelectric aluminate sodalite Sr/sub 8/(Al/sub 12/O/sub 24/)(CrO/sub 4/)/sub 2/ were investigated by selected area and convergent beam electron diffraction ...
We describe powder X-ray diffraction experiments on lithium intercalation compounds. Using a unique electrochemical cell which incorporates a beryllium X-ray window we are able to monitor changes in the host lattice which occur when the lithium concentrati ...
The methanol dehydration reaction was studied over environmentally benign, easily accessible and inexpensive K10 montmorillonite clay used as the catalyst at a temperature range between 200–700 °C. Nearly 100% selectivity towards dimethyl ether (DME) at 80 ...
