Purification of penicillin acylase through a monolith column containing methacryloyl antipyrine
(Elsevier Science BV, 2007)The aim of this work was to test a chromatographic support containing 4-amino-antipyrine for its ability to purify penicillin acylase in crude extract and pure penicillin acylase. First, methacryloyl antipyrine (MAAP) as ... -
Creation of recognition sites for organophosphate esters based on charge transfer and ligand exchange imprinting methods
(Elsevier Science BV, 2006)This manuscript describes a method for the selective binding behavior of paraoxan and parathion compounds on surface imprinted polymers which were prepared using both charge transfer (CT) (methacryloyl-antipyrine, MAAP) ... -
Biosorption of cadmium, lead, mercury, and arsenic ions by the fungus Penicillium purpurogenum
(Marcel Dekker Inc, 2003)The potential use of the fungus Penicillium purpurogenum to remove cadmium, lead, mercury, and arsenic ions from aqueous solutions was evaluated. Biosorption of heavy metal ions reached equilibrium in 4 h. Heavy metal ions ... -
L-histidine imprinted synthetic receptor for biochromatography applications
(American Chemical Society, 2006)We have proposed novel surface-imprinted beads for selective separation of cytochrome c (cyt c) by N-methacryloyl(L)-histidine-copper(II) [MAH-Cu(II)] as a new metal-chelating monomer via metal coordination interactions ... -
Dual quaternionic reformulation of electromagnetism
(Slovak Acad Sciences Inst Physics, 2003)It can be said that Maxwell's equations are one of the well-known equations of Physics. Despite the fact that this equations are more than hundred years old (1865), they still are the cornerstone of electrodynamics. Although ... -
The dynamical Casimir effect for two oscillating mirrors in 3D
(IOP Publishing LTD, 2008)The generation of photons in a three-dimensional rectangular cavity with two moving boundaries is studied by using the multiple scale analysis (MSA). It is shown that the number of photons are enhanced for the cavity whose ... -
Measurements of radon concentrations in well waters near the Aksehir fault zone in Afyonkarahisar, Turkey
(Pergamon-Elsevier Science LTD, 2007)Afyonkarahisar is located in the mid-west Anatolia in Turkey where Aksehir fault zone lies. This earthquake active zone has produced earthquakes in magnitudes from 3.0 to 7.1 in Richter scale. The Rn-222 concentrations in ... -
Dynamical Casimir effect for a swinging cavity
(IOP Publishing LTD, 2009)The resonant scalar particle generation for a swinging cavity resonator in the Casimir vacuum is examined. It is shown that the number of particles grows exponentially when the cavity rotates at a specific external frequency. -
Oscillating and rotating boundary conditions in quantum mechanics
(IOP Publishing LTD, 2011)We consider a particle in an oscillating cavity and in a rotating cavity in the context of moving boundary problems in quantum physics. We use the multiple-scale analysis method to solve the Schrodinger equation subject ... -
PT symmetric Floquet topological phase in SSH model
(Elsevier Science BV, 2018)We consider periodically modulated Su-Schrieffer-Heeger (SSH) model with gain and loss. This model, which can be realized with current technology in photonics using waveguides, allows us to study Floquet topological ... -
Super Bloch oscillation in a PT symmetric system
(Elsevier Science BV, 2016)Wannier-Stark ladder in a PT symmetric system is generally complex that leads to amplified/damped Bloch oscillation. We show that a non-amplified wave packet oscillation with very large amplitude can be realized in a ... -
Discrete rogue waves in an array of waveguides
(Elsevier Science BV, 2015)We study discrete rogue waves in an array of nonlinear waveguides. We show that very small degree of disorder due to experimental imperfection has a deep effect on the formation of discrete rogue waves. We predict long-living ... -
Edge states at the interface of non-Hermitian systems
(Amer Physical Soc, 2018)Topological edge states appear at the interface of two topologically distinct Hermitian insulators. We study the extension of this idea to non-Hermitian systems. We consider PT-symmetric and topologically distinct non-Hermitian ... -
Self-acceleration in non-Hermitian systems
(Elsevier Science BV, 2017)We study self-acceleration in PT and non-PT symmetric systems. We find some novel wave effects that appear uniquely in non-Hermitian system. We explore self-accelerating waves with constant intensity and integrable ... -
Self-accelerating parabolic cylinder waves in 1-D
(Elsevier Science BV, 2016)We introduce a new self-accelerating wave packet solution of the Schrodinger equation in one dimension. We obtain an exact analytical parabolic cylinder wave for the inverted harmonic potential. We show that truncated ... -
Self-oscillating beams in a photonic lattice
(Epl Association, European Physical Society, 2016)We study self-acceleration in a parabolic tight-binding lattice and construct a self-accelerating wave packet in k-space. As opposed to accelerating Airy wave packets in free space, self-acceleration occurs in k-space and ... -
Majorana edge modes with gain and loss
(Amer Physical Soc, 2016)We consider a non-Hermitian generalization of the Kitaev model and study the existence of stable Majorana zero energy modes. We show that they exist in the limit of zero chemical potential even if balanced gain and loss ... -
