Lung carcinoma has become one of the malignancies whose morbidity and mortality are growing significantly. Blood is a functional body fluid, it delivers oxygen and nutrients to the other parts of the body, and it is a pathway of tumor metastasis. This paper studies the possibility of diagnosing lung carcinoma by blood dielectric spectroscopy. Comparison experiments were carried out to trace the...

Recent advances in electron microscope fluid cell design have enabled imaging of samples in aqueous environments and have provided a platform to perform in-situ crystallization experiments as well as electrochemical studies [1-2]. However, the actual SEM imaging contrast mechanisms when imaging through the dielectric membranes of this type of fluid cell device remain unknown. In these experimen...

Structural, thermodynamic, and dielectric properties of a dipolar fluid confined in a charged random matrix are studied by means of grand canonical Monte Carlo simulation and replica Ornstein– Zernike integral equations in the hypernetted chain approximation. The fluid is modeled by a system of dipolar hard spheres. Two matrix topologies are considered: a frozen restricted primitive model matri...

Understanding the effect of inhomogeneity on the charge regulation and dielectric properties, and how it depends on the conformational characteristics of the macromolecules is a long-standing problem. In order to address this problem, we have developed a field-theory to study charge regulation and local dielectric function in planar polyelectrolyte brushes. The theory is used to study a polyaci...

The commonly used optical sensor based on surface plasmon-polariton wave phenomenon can sense just one chemical, because only one SPP wave can be guided by the interface of a metal and a dielectric material contained in the sensor. Multiple analytes could be detected and/or the sensing reliability for a single analyte could be enhanced, if multiple SPP-wave modes could be excited on a single me...

When magnetic fluid is confined with an immiscible fluid between closely spaced parallel plates, and a uniform magnetic field is applied normal to the plates, the interface between the fluids exhibits a threshold instability in which a comblike pattern is established [1]. At supercritical intensities of the magnetic field a mutual invasion of the two phases occurs, in which fingers of magnetic ...

The usual approach to the development of new nonlinear dielectric materials focuses on the search for materials in which the components possess an inherently large nonlinear dielectric response. In contrast, based on thermodynamics, we have presented a first-principles approach to obtain the electrostriction-induced effective third-order nonlinear susceptibility for electrorheological (ER) flui...

Functional brain imaging has tremendous applications. The existing methods for functional brain imaging include functional Magnetic Resonant Imaging (fMRI), scalp electroencephalography (EEG), implanted EEG, magnetoencephalography (MEG) and Positron Emission Tomography (PET), which have been widely and successfully applied to various brain imaging studies. To develop a new method for functional...
