(Methyldiphenylphosphoranylidene)ammonium chloride [PDF]
Acta Crystallographica Section E, 2009 The title compound, C13H15NP+·Cl−, was obtained by hydrolysis of the N-trimethysilyl derivative of methydiphenyliminophosphine. The dihedral angle between the phenyl rings in the cation is 61.5 (3)°.

Shape of ammonium chloride dendrite tips at small supersaturation [PDF]
J. Cryst. Growth, 274 (2005) 233-240, 2004 We report detailed shape measurements of the tips of three-dimensional ammonium chloride dendrites grown from supersaturated aqueous solution. For growth at small supersaturation, we compare two different models: parabolic with a fourth-order correction,

(1-Naphthylmethyl)ammonium chloride [PDF]
Acta Crystallographica Section E, 2010 The reaction of 1-naphthylmethylamine and hydrochloric acid in a 1:1 molar ratio resulted in the formation of the 1:1 proton-transfer compound, C11H12N+·Cl−. In the crystal, the ions are linked by N—H...Cl hydrogen bonds into

Quantitative Determination of the Adiabatic Condition Using Force-Detected Nuclear Magnetic Resonance [PDF]
Phys. Rev. B 72, 224402 (2005), 2006 The adiabatic condition governing cyclic adiabatic inversion of proton spins in a micron-sized ammonium chloride crystal was studied using room temperature nuclear magnetic resonance force microscopy.

The Transient Growth of Ammonium Chloride Dendrites [PDF]
Journal of Crystal Growth, 2006 We report measurements of the initial growth and subsequent transient response of dendritic crystals of ammonium chloride grown from supersaturated aqueous solution. Starting from a small, nearly spherical seed held in unstable equilibrium, we lower the temperature to initiate growth.

Computational Study of the Structure and Thermodynamic Properties of Ammonium Chloride Clusters Using a Parallel J-Walking Approach [PDF]
J. Chem. Phys. 104 (1996) 8690, 1996 The thermodynamic and structural properties of (NH$_4$Cl)$_n$ clusters, n=3-10 are studied. Using the method of simulated annealing, the geometries of several isomers for each cluster size are examined.

Dominant aerosol processes during high-pollution episodes over Greater Tokyo [PDF]
, 2007 This paper studies two high-pollution episodes over Greater Tokyo: 9 and 10 December 1999, and 31 July and 1 August 2001. Results obtained with the chemistry-transport model (CTM) Polair3D are compared to measurements of inorganic PM2.5. To understand to

Formation of Chimneys in Mushy Layers: Experiment and Simulation [PDF]
arXiv, 2011 In this fluid dyanmics video, we show experimental images and simulations of chimney formation in mushy layers. A directional solidification apparatus was used to freeze 25 wt % aqueous ammonium chloride solutions at controlled rates in a narrow Hele ...

Ammonium chloride alters neuronal excitability and synaptic vesicle release
Scientific Reports, 2017 Genetically encoded pH-sensors are widely used in studying cell membrane trafficking and membrane protein turnover because they render exo-/endocytosis-associated pH changes to fluorescent signals.
