Spectral induced polarization for monitoring electrokinetic remediation processes

, 2014
Electrokinetic remediation is an emerging technology for extracting heavy metals from contaminated soils and sediments. This method uses a direct or alternating electric field to induce the transport of contaminants toward the electrodes.

Polar or Apolar—The Role of Polarity for Urea-Induced Protein Denaturation

PLoS Computational Biology, 2008
Urea-induced protein denaturation is widely used to study protein folding and stability; however, the molecular mechanism and driving forces of this process are not yet fully understood. In particular, it is unclear whether either hydrophobic or polar interactions between urea molecules and residues at the protein surface drive denaturation. To address

Mask-induced polarization [PDF]

SPIE Proceedings, 2004
The objective of this paper is to study the polarization induced by mask structures. Rigorous coupled-wave analysis (RCWA) was used to study the interaction of electromagnetic waves with mask features. RCWA allows the dependence of polarization effects of various wavelengths of radiation on grating pitch, profile, material, and thickness to be studied.

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

FEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Generation and characterization of polarization scrambled optical signals [PDF]

, 2012
Controlling the state of polarization of a light beam of an optical fiber is of crucial importance. Non-Linear Polarization Pulling (NLPP) is an all-optical way to control the state of polarization of signals which has been proposed in recent years ...
