Sodium Azide Resistance in Proteus hauseri [PDF]
SUMMARY: The sodium azide resistance of Proteus hauseri is not of the all-or-none unilocal type reported for Escherichia coli but rather of the obligatory multi-step or penicillin variety. Independently isolated 1st-step resistant variants possessed similar degrees of resistance to sodium azide. Some properties of azide-resistant variants of P. hauseri

Sodium Pentazolate: a Nitrogen Rich High Energy Density Material [PDF]
Sodium pentazolates NaN5 andNa2N5, new high energy density materials, are discovered during first principles crystal structure search for the compounds of varying amounts of elemental sodium and nitrogen. The pentazole anion N5- is stabilized in the condensed phase by sodium Na+ cations at pressures exceeding 20 GPa, and becomes metastable upon release

Dynamic Light Scattering based microrheology of End-functionalised triblock copolymer solutions [PDF]
'Soft' patchy surfactant micelles have become an additional building tool in self-assembling systems. The triblock copolymer, Pluronic F108, forms spherical micelles in aqueous solutions upon heating leading to a simple phase diagram with a micellar crystalline solid at higher temperatures and concentrations.

Structure, elastic and dynamical properties of KN$_3$ and RbN$_3$: A van der Waals density functional study [PDF]
We report a detailed first principles study on the structural, elastic, vibrational and thermodynamic properties of layered structure energetic alkali metal azides KN$_3$ and RbN$_3$. All the calculations were carried out by means of plane wave pseudopotential method with and without including van der Waals interactions.

Analytical Validation of Two Assays for Equine Ceruloplasmin Ferroxidase Activity Assessment
Ceruloplasmin (Cp) assessment in biological samples exploits the oxidase activity of this enzyme against several substrates, such as p-phenylenediamine (p-P), o-dianisidine (o-D) and, most recently, ammonium iron(II) sulfate (AIS).

Phase stability and lattice dynamics of ammonium azide under hydrostatic compression [PDF]
We have investigated the effect of hydrostatic pressure and temperature on phase stability of hydro-nitrogen solids using dispersion corrected Density Functional Theory calculations. From our total energy calculations, Ammonium Azide (AA) is found to be the thermodynamic ground state of N$_4$H$_4$ compounds in preference to Trans-Tetrazene (TTZ), Hydro-

Poly[μ-azido-(μ3-nicotinato N-oxide)zinc(II)]
The title compound, [Zn(C6H4NO3)(N3)], has been prepared by the reaction of nicotinate N-oxide acid, zinc(II) nitrate and sodium azide. The Zn atom is five coordinated by two azide anions and three nicotinate N-oxide ligands.
