This contribution summarizes the use of plasmon surface polaritons and guided optical waves for the characterization of interfaces and thin organic films. After a short introduction to the theoretical background of evanescent wave optics, examples are given that show how this interfacial "light" can be employed to monitor thin coatings at a solid/air or solid/liquid interface. Examples are give...

The technique of wavelength scanning digital holographic microscopy (WSDHM) is improved by use of a digital spectral shaping method which is used to suppress the sidelobes of the amplitude modulation function in WSDHM for non-Gaussian-shaped source spectra. Spurious structures caused by sidelobes can be eliminated in tomographic imaging and the performance of the tomographic system greatly impr...

the effect of mentha spicata l. extract on the corrosion behaviour of carbon steel in 1.0 m hcl solution was investigated using polarization, electrochemical impedance spectroscopy (eis) and electrochemical noise (en) techniques. the solution containing 250 ppm of the ethanolic solution of extract showed the highest inhibition efficiency (ie). the effect of temperature on the rate of corrosion ...

the aim of this study was to determine the feasibility of coupling an electrochemical process with a biological treatment in order to degrade phosmet, an organophosphorous pesticide. the absence of biodegradability of phosmet by pseudomonas fluorescens and activated sludge was verified in our operational conditions. so, a conventional biological treatment is not appropriate for phosmet polluted...

several transporters appear to be important in transporting various drugs. many patients, who receive morphine as analgesic medication, also receive other medications with potency of changing morphine transport by affecting p-glycoprotein (p-gp) and oatp2 transport system. this could influence morphine pharmacokinetics and pharmacodynamics. the aim of present study was to elucidate the transpor...

Many cell types, including neurons, chromaffin cells of the adrenal adrenal gland and mast cells, release transmitter molecules stored in ‘vesicles’ by a process called exocytosis. In this process, an intracellular vesicle loaded with molecules to be secreted, fuses with the cell membrane, forming an initial opening called a fusion pore, and emits its contents into the extracellular space. The ...

The issue of air quality has attracted more and attention. main methods for monitoring the concentration pollutants in include national station micro detector testing. Since electrochemical sensor is susceptible to interference, monitored data a certain deviation. In this paper, combined model partial least square regression random forest (PLS-RFR) used correct detection detector. First, correl...
