On the solubility of Nd3+ in Y3Al5O12 [PDF]
Journal of Alloys and Compounds 436 (2007) 204-208, 2008 Neodymium doped yttrium aluminum garnet powders (Nd:YAG or (Y{1-x}Nd{x})3Al5O12, x=0.15, 0.25, or 0.30, respectively) were prepared by a sol-gel technique. By DTA measurements up to 2000 deg C eutectic and liquidus temperatures could be determined. Exothermal peaks in the second and subsequent DTA heating runs indicate that the crystallized DTA samples

Study of aluminoborane compound AlB_4H_(11) for hydrogen storage [PDF]
, 2009 Aluminoborane compounds AlB_4H_(11), AlB_5H_(12), and AlB_6H_(13) were reported by Himpsl and Bond in 1981, but they have eluded the attention of the worldwide hydrogen storage research community for more than a quarter of a century.

Advanced Engineering Materials, EarlyView.Developing process parameters for the laser‐based Powder Bed Fusion of metals can be a tedious task. Based on melt pool depth, the process parameters are transferable to different laser scan speeds. For this, understanding the melt pool scaling behavior is essential, particularly for materials with high thermal diffusivity, as a change in scaling ...

Mechanism of immunopotentiation and safety of aluminum adjuvants
Frontiers in Immunology, 2013 Aluminum-containing adjuvants are widely used in preventive vaccines against infectious diseases and in preparations for allergy immunotherapy. The mechanism by which they enhance the immune response remains poorly understood.

Vapor pressure and evaporation rate of certain heat-resistant compounds in a vacuum at high temperatures [PDF]
The vapor pressure and evaporation rate of borides of titanium, zirconium, and chrome; and of strontium and carbides of titanium, zirconium, and chrome, molybdenum silicide; and nitrides of titanium, niobium, and tantalum in a vacuum were studied.

K-edge XANES of octahedral aluminum compounds: similarities and differences via the analysis of excitonic properties [PDF]
arXivThis study presents an \textit{ab initio} investigation of the XANES spectra at the aluminum K edge for three compounds: Al$_2$O$_3$, AlF$_3$ and AlCl$_3$, where the Al atoms share the same oxidation state~(III) and are coordinated in an octahedral symmetry.

Gallium substitution in PuCoGa5 [PDF]
arXiv, 2016 The substitution of gallium by aluminum, germanium, tin and indium in PuCoGa5, the actinide-based superconductor with the highest critical temperature, has been investigated. Only systems with 20% substitution by Al and Ge (i.e. PuCoGa4Al and PuCoGa4Ge) have been successfully synthesized by annealing arc-melted samples.
