High-Resolution Ultrasonic Spectroscopy: Looking at the Interpolyelectrolyte Neutralization from a Different Perspective

نویسندگان

چکیده

In this study, the high-resolution ultrasonic spectroscopy (HR-US) technique was applied to examine interpolyelectrolyte neutralization. The mentioned method tested on example of complexation between poly(allylammonium) cations and poly(acrylate) anions in aqueous solutions at pH = 7. It confirmed by HR-US that type titration (stepwise or abrupt), direction titration, background salt affect outcome obtained results were explained basis velocity attenuation changes context suspension compressibility, a parameter is extremely sensitive molecular organization intermolecular interactions. Moreover, measurements proved be consistent with previous more traditional methods such as dynamic light scattering, microcalorimetry, electrokinetics. This research demonstrates convenient reliable can employed for investigation neutralization polyelectrolyte-related processes.

Looking at microbial metabolism by high-resolution 2H-NMR spectroscopy

We analyzed the applicability of high-resolution (2)H-HMR spectroscopy for the analysis of microbe metabolism in samples of mitochondrion isolated from rat liver and from aqueous extracts of homogenates of rat liver and other organs and tissues in the presence of high D2O contents. Such analysis is possible due to the fast microbe adaptation to life in the heavy water. It is also shown that som...

Looking at Computations from a Different Angle

We present a novel framework to reason about programs based on encodings of computations as graphs. The main insight here is to rearrange the programs such that given a bound k, each computation can be explored according to any tree decomposition of width k of the corresponding behaviour graph. This produces under-approximations parameterized on k, which result in a complete method when we rest...

A Forward-Looking High-Resolution GPR System

A high-resolution ground penetrating radar (GPR) system was designed to help define the optimal radar parameters needed for the efficient standoff detection of buried and surface-laid antitank mines. The design requirements call for a forward-looking GPR capable of detecting antitank mines in a 5 to 8 meter wide swath, 7 to 60 meters in front of a mobile platform. The system has a resolution go...
