Genetics and physiology of motility by Photorhabdus spp
… and not at the gene expression level. This ionic salt posttranscriptional regulation of motility has not been observed in other bacteria. We suggest that this form of regulation may be beneficial for an organism that must adapt quickly to changing environments.</p><p>To identify the genes …

A Study of the Non-linear Variation in the Temperature of the Water Density Anomaly as a Function of Solute Concentration
… carried out in this study. For solutes such as ionic salts and sugars, the temperature of maximum density decreases in a linear manner as the solute concentration increases (‘Despretz law’). It had been noted, however, in previous work that for monohydric alcohols such as methanol and ethanol …

Functional ionic liquids in crystal engineering and drug delivery
… of this research is to explore the use of ionic liquds in crystal engineering and drug delivery. Ionic liquids have a wide range of applications in pharmaceutical field due to their unique physicochemical propertie ssuch as chemical, thermal stability, low melting point, nonvolatility, …

Effect of halite and calcite coatings on thermal infrared spectra wih implications for Mars exploration
… the occurrence and distribution of soluble ionic salts allows us to model the aqueous history and geochemical conditions of surface solutions on Mars. Salts deposited as coatings are particularly important for attaining this knowledge because the thermal infrared (TIR) remote sensing method …

Quantifying the adhesion of noble metal foulants on structural materials in a Molten Salt Reactor
… in their elemental forms rather than becoming ionic salts. Coalescing in the primary fluid, these noble metals then migrate and eventually deposit on internal reactor surfaces. Since the bulk of these noble metal fission products are also energetically unstable they bring not only physical …

MULTI-IONIC LITHIUM SALTS FOR USE IN SOLID POLYMER ELECTROLYTES FOR LITHIUM BATTERIES
… use liquid electrolytes because of their high ionic conductivity (>10-3 S/cm) over a broad range of temperatures, high dielectric constant, and good electrochemical stability with the electrodes (mainly the cathode cathode). The disadvantages of their use in lithium ion batteries are that they …

A Study of the Change in the Temperature of Maximum Density of Water and Aqueous Solutions as a function of Pressure
… depending on the nature of the solute. For ionic salts, the rate of decrease is steeper than that for pure water, whereas for monohydric alcohols the rate of decrease is less that that for pure water. These divergent trends become more apparent as solute concentrations increase. The …

Organic Self-Assembled Layer-by-Layer Thin Films for Second-Order Nonlinear Optics
… a surface by electrostatic effects is called the Ionically Self-Assembled Monolayer or ISAM method. The role of the optically inactive polycation's structure on deposition and chromophore orientation was studied by fabricating films with several different polycations. While the specific …

Cs-Pb-Br Core-shell Perovskite Microcrystals for Stability Improvement
… developed since 2014. Due to their intrinsic ionic salts and lead-halogen composition, they have high molar absorbance coefficient, high defect tolerance, and ultra-fast carrier mobility, and their material structure and optical properties can be precisely controlled through ion exchange, …

Comparison of Cation-Anion Oxidizer Pairings in Electrically Controllable Solid Propellants
… mobility is associated with the size of the ionic radii. Additionally, neat oxidizer pellets were electrically decomposed to determine their linear regression rate. These results help to characterize the mechanism of reaction. This advances the knowledge of oxidizers in electrically …

Tailoring Structure and Function of Imidazole-Containing Block Copolymers for Emerging Applications from Gene Delivery to Electromechanical Devices
… of applications including gene delivery vectors, ionic liquids, electromechanical actuators, and novel monomers and polymers. The imidazole ring provides a unique building block for these applications due to its thermal stability, aromatic nature, ability to form ionic salts, and ease of …

Hyphenation of analytical techniques to single cell capillary electrophoresis-mass spectrometry
… applications because it favors the injection of ionic salts into the capillary, which causes ion suppression at the electrospray interface. We addressed this by incorporating a desalting step into the sample preparation, which preserved metabolite material while precipitating interfering salts. …
