Detecting Traces of 17α-Ethinylestradiol in Complex Water Matrices

Sensors, 2020
Hormones have a harmful impact on the environment and their detection in water bodies is an urgent matter. In this work, we present and analyze a sensor device able to detect traces of the synthetic hormone 17α-ethinylestradiol (EE2) below 10−9 M in ...

Dependence of the elastic modulus of powder coatings on their porosity in electrical contact hardening

Проблеми трибології, 2021
The relationship between the elastic modulus and the porosity of powder coatings has been investigated for different methods of their deposition. Porosity is the main means of assessing the quality of coatings and depends on the techniques for their ...

Electric Modulus and Scaling of Chitosan/PVA Biopolymer Blend [PDF]

Egyptian Journal of Chemistry, 2021
Dielectric measurements of chitosan/PVA polymer blends were performed at various temperatures in a wide frequency range. Higher values of / and // at higher temperatures and lower frequencies are correlated to interfacial polarization (IP) and DC conduction, respectively.

CP-violating phases in the CKM matrix in orbifold compactifications [PDF]

, 1998
The picture of CP-violation in orbifold compactifications in which the $T$-modulus is at a complex fixed point of the modular group is studied. CP-violation in the neutral kaon system and in the neutron electric dipole moment are both discussed.

Electrical and Dielectric Properties of Copper Ion Conducting Solid Polymer Electrolytes Based on Chitosan: CBH Model for Ion Transport Mechanism

International Journal of Electrochemical Science, 2018
Copper ion-conducting polymer electrolytes based on chitosan (CS) were prepared using solution-cast technique. The CS host polymer was complexed with different weight percent copper iodide (CuI) salt.

Dielectric and thermal relaxation in the energy landscape [PDF]

, 2006
We derive an energy landscape interpretation of dielectric relaxation times in undercooled liquids, comparing it to the traditional Debye and Gemant-DiMarzio-Bishop pictures. The interaction between different local structural rearrangements in the energy

Fractional and semi-local non-Abelian Chern-Simons vortices [PDF]

, 2010
In this paper we study fractional as well as semi-local Chern-Simons vortices in G = U(1) x SO(2M) and G = U(1) x USp(2M) theories. The master equations are solved numerically using appropriate Ansatze for the moduli matrix field.
