Silver–silica transparent metal structures as bandpass filters for the ultraviolet range
(IOP Publishing, 2005)
We designed and produced silver–silicon dioxide multilayer thin-film bandpass filters for the ultraviolet range by applying the concept of 'transparent metals'. To calculate the transmission of the designed metallodielectric ...
The thermal stability of the external invertase isoforms from Saccharomyces cerevisiae correlates with the surface charge density
(Elsevier France-Editions Scientifiques Medicales Elsevier, Paris, 2012)
Understanding the effect of surface charge on the stability of proteins is one prerequisite for "tailoring" proteins with increased thermal stability. Here, we investigated the origin of the altered thermal stability ...
Configurational, LFDFT and NBO analysis of chromium(III) complexes of edta-type ligands
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
A new hexadentate chromium(III) complex, Na[Cr(1,3-pd3ap)]center dot 3H(2)O, containing an unsymmetrical edta-type ligand, the 1,3-propanediamine-N,N,N'-triacetate-N'-3-propionate ion (1,3-pd3ap), has been prepared, ...
Effect of pH and human serum albumin on the cytotoxicity of a glucuronide prodrug of 9-aminocamptothecin
(Switzerland : Springer Nature, 2007)
Purpose: 9-aminocamptothecin glucuronide (9ACG) is a prodrug of 9-aminocamptothecin (9AC) that displays potent antitumor activity against human tumor xenografts in nude mice. Camptothecins exist in a pH dependent equilibrium ...
Performance limits to the operation of nanoplasmonic chemical sensors: noise-equivalent refractive index and detectivity
(Spie-Soc Photo-Optical Instrumentation Engineers, Bellingham, 2009)
We considered figures of merit for chemical and biological sensors based on plasmonic structures and utilizing adsorption/desorption mechanism. The operation of these devices in general is limited by noise determining the ...
DNA Sequencing with Single-Stranded DNA Rectification in a Nanogap Gated by N‑Terminated Carbon Nanotube Electrodes
(American Chemical Society (ACS), 2020)
Fast, reliable, and inexpensive DNA sequencing is an important pursuit in healthcare, especially in personalized medicine with possible deep societal impacts. Despite significant progress in various nanopore-based sequencing ...
Oxygen Reduction on Polycrystalline Pt and Au Electrodes in Perchloric Acid Solution in the Presence of Acetonitrile
(Esg, Belgrade, 2011)
Oxygen reduction reaction (ORR) was studied on polycrystalline Pt and Au electrodes in 0.1 M HClO(4) solutions containing various amounts of acetonitrile (AcN). The state of the electrode surface was characterized by cyclic ...
The kinetics of ethanol adsorption from the aqueous phase onto zeolite NaZSM-5
(Springer, New York, 2008)
The kinetics of the isothermal adsorption of ethanol from an aqueous solution onto a hydrophobic zeolite of the NaZSM-5 type in the temperature range 298-333 K was investigated. Specific shape parameters of the adsorption ...
Cholesterol bound to hemoglobin in normal human erythrocytes: a new form of cholesterol in circulation?
(Elsevier, 2004)
Objective: To study lipid fraction that is occasionally observed in red blood cell (RBC) hemolysate (supernatants from which membranes were separated). Study design: Plasma lipid profiles, cholesterol (Ch) and phospholipids ...
Periodic Operation with Modulation of Inlet Concentration and Flow Rate Part I: Nonisothermal Continuous Stirred-Tank Reactor
(Wiley, 2016)
The nonlinear frequency response (NFR) method, which is an analytical, fast, and easy method for evaluating the performance of forced periodically operated chemical reactors, was used to investigate possible improvements ...
