A simple electrospinning method is developed to introduce signal transduction ability into molecularly imprinted nanofibers.

original article   electrospun nanofibrous filter media have attracted considerable attention in the last decade. the present study aimed to develop the electrospun pan (polyacrylonitrile) filter media through experimental investigations for application in high-performance air filters. for this purpose, an experimental design was proposed to assess the effect of electrospinning process conditio...

Quantum yields for charge transport across adenine tracts of increasing length have been measured by monitoring hole transport in synthetic oligonucleotides between photoexcited 2-aminopurine, a fluorescent analogue of adenine, and N(2)-cyclopropyl guanine. Using fluorescence quenching, a measure of hole injection, and hole trapping by the cyclopropyl guanine derivative, we separate the individ...

We have observed coherent optical and acoustic phonon generation, which are strongly coupled to the charge-ordering sCOd transition in La1−xCaxMnO3 sx=0.5, 0.58d using femtosecond optical pump-probe spectroscopy. Coherent optical phonons, observed at low temperatures, disappear above the charge-ordering temperature TCO, while coherent acoustic phonons display the opposite behavior, disappearing...

This article discusses the variability and constancy of two fundamental properties of the electron: its mass and its electric charge. Mainstream physics considers the mass of the electron as varying with its velocity while its electric charge as a fundamental constant of physics (Section 1). On the other hand, many other physicists maintain the opposite concept: the mass of the electron is cons...

We contrast the adsorption, over a wide range of pH and ionic strength, of polyelectrolyte chains with different fractions of charged segments but similar degree of polymerization. The system was a cationic polymer, poly~1,4 vinyl!pyridine ~PVP!, with 14%, 48%, and 98% quaternized repeat units, adsorbed from aqueous solution ~D2O or H2O! onto a single silicon oxide substrate at 25 °C. Measureme...

Unravelling the lithium-ion transport mechanism in α-Fe2O3 nanofibers through situ electrochemical impedance studies is crucial for realizing their application high-performance anodes batteries. Herein, we report effect of heat treatment conditions on structure, composition, morphology, and properties as an anode The were synthesized via electrospinning post-annealing with differences annealing...

Electrostatic interactions between charges on ligands and charges on proteins that are remote from the binding interface can influence the free energy of binding (delta Gb). The binding affinities between charged ligands and the members of a charge ladder of bovine carbonic anhydrase (CAII) constructed by random acetylation of the amino groups on its surface were measured by affinity capillary ...

Combining atomistic molecular dynamic simulations, Marcus-Hush theory description of charge transport rates, and master equation description of charge dynamics, we correlate the temperature-driven change of the mesophase structure with the change of charge carrier mobilities in columnar phases of hexabenzocoronene derivatives. The time dependence of fluctuations in transfer integrals shows that...

Though often considered as one of the main driving process of the complexation of species of opposite charges, the release of counterions has never been experimentally directly measured. We present here the first structural determination of such a release by Small Angle Neutron Scattering in complexes made of lysozyme, a positively charged protein and of PSS, a negatively charged polyelectrolyt...
