The initial growth of sidebranches in ammonium chloride dendrites [PDF]

open access: yesJ. Crystal Growth, 523, 1 October 2019, 125162, 2012
We report measurements for the initial stages of sidebranching during the dendritic growth of ammonium chloride from supersaturated aqueous solution. The earliest sidebranches are approximately periodic; they are first evident about $36 \rho$ behind the tip, where $\rho$ is the tip radius, and have an average initial spacing of about $5 \rho$, though ...

Synergy of ammonium chloride and moisture on perovskite crystallization for efficient printable mesoscopic solar cells

open access: yesNature Communications, 2017
Organometal lead halide perovskites have been widely used as the light harvester for high-performance solar cells. However, typical perovskites of methylammonium lead halides (CH3NH3PbX3, X=Cl, Br, I) are usually sensitive to moisture in ambient air, and

Effect of long-term changes in soil chemistry induced by road salt applications on N-transformations in roadside soils [PDF]

open access: yes, 2008
Of several impacts of road salting on roadside soils, the potential disruption of the nitrogen cycle has been largely ignored. Therefore the fates of low-level ammonium-N and nitrate-N inputs to roadside soils impacted by salting over an extended period (

A simple blood-culture bacterial pellet preparation for faster accurate direct bacterial identification and antibiotic susceptibility testing with the VITEK 2 system. [PDF]

open access: yes, 2013
An ammonium chloride procedure was used to prepare a bacterial pellet from positive blood cultures, which was used for direct inoculation of VITEK 2 cards. Correct identification reached 99% for Enterobacteriaceae and 74% for staphylococci.

Utilization of Ammonium Chloride as a Novel Selective Depressant in Reverse Flotation of Potassium Chloride

open access: yesMinerals, 2019
The separation of sylvite (KCl) and halite (NaCl), two main minerals in potash ores, is difficult because of the high ion concentration, fine particles of NaCl, and aggregation of KCl and NaCl in the saturated system.

Proper orthogonal decomposition analysis for two-oscillating grid turbulence with viscoelastic fluids

open access: yesAdvances in Mechanical Engineering, 2016
In this article, the experiments of two-oscillating grid turbulence with viscoelastic fluids were carried out using particle image velocimetry. Two classical drag-reducing additives with viscoelastic characteristics were chosen: polymer (polyacrylamide ...

Ammonothermal Synthesis and Crystal Structures of Diamminetriamidodizinc Chloride [Zn2(NH3)2(NH2)3]Cl and Diamminemonoamidozinc Bromide [Zn(NH3)2(NH2)]Br

open access: yesInorganics, 2016
The treatment of excess zinc in the presence of ammonium chloride under ammonothermal conditions of 873 K and 97 MPa leads to diamminetriamidodizinc chloride [Zn2(NH3)2(NH2)3]Cl with a two-dimensionally μ-amido-interconnected substructure.
