We have developed a simple, fast, and accurate method to measure the absolute number concentration of nanoparticles in solution. The combines electrospray differential mobility analysis (ES-DMA) with statistical droplet-induced oligomer formation. A key feature is that it allows determination particles by knowing only droplet size generated from particular ES source, thereby eliminating need for sample-specific calibration standards or detailed transport losses. approach was validated...

Primary microglia isolated from newborn rats human microglial clone 3 (HMC3) cells were stimulated with IL-1β followed by FMN incubation. The cell viability inflammatory cytokine levels detected....

Electrospray (ES) sources are commonly used to introduce nonvolatile materials (e.g., nanoparticles, proteins, etc.) the gas phase for characterization by mass spectrometry or ion mobility. Recent studies in our group using ES mobility characterize protein aggregation solution have raised question as whether itself induces and thus corrupts results. In this article, we develop a statistical model determine extent which process formation of dimers higher-order aggregates. The is validated...

The mobility of a nonspherical particle is function both shape and orientation. Thus, unlike spherical particles, the mobility, through its orientation, depends on magnitude electric field. In this work, we develop general theory, based an extension work Happel Brenner (1965), for orientation-averaged applicable to any axially symmetric which friction tensor polarization energy are known. By using Boltzmann probability distribution employ formulation computing rather than scalar analysis...

In order to improve algorithm efficiency and performance, a technique for image fusion based on the Non-subsampled Contourlet Transform (NSCT) domain an Accelerated Non-negative Matrix Factorization (ANMF)-based is proposed in this paper. Firstly, registered source images are decomposed multi-scale multi-direction using NSCT method. Then, ANMF executed low-frequency sub-images get low-pass coefficients. The low frequency fused can be generated faster that update rules W H optimized less...

An inter-band carrier aggregation (CA) quadplexer allows doubling the download rates and is therefore an important element in upcoming mobile phone systems. In a duplexer design, both Tx Rx filters should behave like open-circuit for respective counter-bands at antenna port. Additionally, they have to attain high suppression their counter-band get good in-band isolation. The situation gets more difficult challenging CA quadplexer. Besides requirement now 3 bands simultaneously, each filter...

The mobility of a nonspherical particle is function both shape and orientation. In turn, the higher magnitude electric field causes particles to align more along direction, increasing their or decreasing diameter. previous works, Li et al. developed general theory for orientation-averaged dynamic factor applicable any axially symmetric in an field, applied it specific cases nanowires doublets spheres. this work, nanowire compared with experimental results gold nanorods known determined by...

For a nonspherical particle, standard differential mobility analyzer (DMA) measurement yields mobility-equivalent spherical diameter, but provides no information about the degree of sphericity. However, given that electrical for nonspheres is orientation-dependent, and orientation can be manipulated using electric fields varying strength, one can, in principle, extract some type shape through systematic as function particle orientation. Here, we describe development pulsed-field (PFDMA)...
