    ABSTRACT: The ultra-dispersive powders of alumolutetium garnets activated by Ce 3+ ions have been obtained by colloid chemical approach. Those spectral luminescence properties and crystal structure as function of activator concen tration and temperature treatment of precursor have been studied by means of optical spectroscopy, X-ray and neutron diffraction. The changes in structure parameters of these compounds depends on synthesis conditions and, as result, the distortion in crystal environmental of Се 3+ ions change luminescence intensity of those com- pounds. It was found that maximum of luminescence intensity for this compounds have been observed at activator concentration of 1.0 wt.% and at annealing temperature region of 1200—1300°С.

    ABSTRACT: One aerobic and four anaerobic batch fermentations of the yeast Saccharomyces cerevisiae were conducted in a stirred bioreactor and monitored inline by NIR spectroscopy and a transfl ectance dip probe. From the acquired NIR spectra, chemometric partial least squares regression (PLSR) models for predicting biomass, glucose and ethanol were constructed. The spectra were directly measured in the fermentation broth and successfully inspected for adulteration using our novel data pre-processing method. These adulterations manifested as strong fluctuations in the shape and offset of the absorption spectra. They resulted from cells, cell clusters, or gas bubbles intercepting the optical path of the dip probe. In the proposed data pre-processing method, adulterated signals are removed by passing the time-scanned non-averaged spectra through two fi lter algorithms with a 5% quantile cutoff. The filtered spectra containing meaningful data are then averaged. A second step checks whether the whole time scan is analyzable. If true, the average is calculated and used to prepare the PLSR models. This new method distinctly improved the prediction results. To dissociate possible correlations between analyte concentrations, such as glucose and ethanol, the feeding analytes were alternately supplied at different concentrations (spiking) at the end of the four anaerobic fermentations. This procedure yielded low-error (anaerobic) PLSR models for predicting analyte concentrations of 0.31 g/l for biomass, 3.41 g/l for glucose, and 2.17 g/l for ethanol. The maximum concentrations were 14 g/l biomass, 167 g/l glucose, and 80 g/l ethanol. Data from the aerobic fermentation, carried out under high agitation and high aeration, were incorporated to realize combined PLSR models, which have not been previously reported to our knowledge.

    ABSTRACT: Spectral-kinetic characteristics of planar plasmonic nanostructures based on polymer films with ordered silver nanoparticles (Ag-NPs) were studied in the spectral range near the surface-plasmon resonance absorption (SPRA) using a femtosecond spectrometer. The Ag-NPs were synthesized in the polymer matrix from a precursor that was added beforehand to the starting photopolymerizable composition and was ordered using several laser beams to photopolymerize the composition. The influence of the degree of Ag-NP ordering on the transient SPRA spectra and relaxation dynamics of induced changes near the SPRA was discussed.

    ABSTRACT: The aim of this study was to test a simple and inexpensive method of electrospinning in order to produce narrow diameter nanofi bers for industrial applications. The zirconium oxide nanofi ber is made by electrospinning on an aluminum plate. In this method, a high voltage is applied between the needle of a syringe and an aluminum plate. A viscous liquid is poured into the syringe and a jet is produced on the desired plate due to high voltage. The crystalline structure and morphology of the produced nanofi bers were studied by XRD and SEM. Results showed that nanofi bers with a smaller diameter were produced at higher annealing temperatures.

    ABSTRACT: T1 values in pure D2O and D2O solutions of human serum albumin (HSA) were measured versus temperature. A formula was derived based on H–H interactions between the surface HDO and non-exchangeable protein protons. The formula was used to evaluate the average distance of the interactions (rav). The effective correlation times were then derived by replacing the experimental data in the formula. Short correlation times obtained for the solution with low HSA (0.02 g albumin for one ml of D2O) decreased from 53 to 29 ps, while longer times increased from 1.19 to 2.22 ns. They are of the order of a fraction of a nanosecond for the solution with high HSA (0.08 g albumin per one ml of D2O). The perfect consistency between the derived theory and experimental data indicates that the high-field 1/T1 in D2O solutions of albumin is caused by dipolar interactions between the surface HDO and non-exchangeable protein protons. It also suggests that the effective correlation time of the surface HDO is of the order of the mean lifetime of short-lived surface water.

    ABSTRACT: In excitation–emission fluorescence spectroscopy, the simultaneous quantitative prediction and qualitative resolution of mixtures of fluorophores using chemometrics is a major challenge because of the scattering and reabsorption effects (turbidity) presented mainly in biomaterials. The measured fluorescence spectra are distorted by multiple scattering and reabsorption events in the surrounding medium, thereby diminishing the performance of the commonly used three-way resolution methods such as parallel factor (PARAFAC) analysis or multivariate curve resolution– alternating least squares (MCR-ALS). In this work we show that spectral loadings and concentration profiles from model mixtures provided using PARAFAC and MCR-ALS are severely distorted by reabsorption and scattering phenomena, although both models fit rather well the experimental data in terms of percentage of the explained variance. The method to correct the fluorescence excitation–emission matrix (EEM) consisted in measuring the optical properties (absorption parameter μa, scattering parameter μs, and anisotropy factor g) of samples and calculating the corresponding transfer function by means of the Monte Carlo simulation method. By applying this transfer function to the measured EEM, it was possible to compensate for reabsorption and scattering effects and to restore the ideal EEM, i.e., the EEM that is due only to fluorophores, without distortions from the absorbers and scatterers that are present. The PARAFAC and MC-RALS decomposition of the resulting ideal EEMs provided spectral loadings and concentration profiles that matched the true profiles.

    ABSTRACT: In2S3 thin fi lms are grown on glass substrates by vacuum thermal evaporation followed by annealing in vacuum between 330 and 400 °C for different time durations. We have investigated the infl uence of the annealing parameters on the characteristics of thin fi lms. It is shown that thermal treatment changed the crystal structure and optical energy band gap of In2S3 thin fi lms. Two energy band gaps were determined for all the fi lms, one indirect and the other direct.

    ABSTRACT: The propagation of electromagnetic waves is examined in inhomogeneous media where the product of the permittivity and permeability is independent of position. A plasma-like frequency dispersion of the refractive index in these media is predicted. It is established that there is a cutoff frequency below which electromagnetic waves cannot be excited in these media. In general, two types of inhomogeneous waves can propagate in these media: transverse electric and transverse magnetic. The magnetic field of the transverse electric waves has a longitudinal component and is elliptically polarized in the plane formed by the wave normal and the gradient of the parameters of the medium. The electric field of the transverse magnetic waves has similar properties.

    ABSTRACT: The acousto-optical diffraction of Bessel light beams (BLB) propagating near the optical axis of uniaxial gyrotropic crystals is examined. It is shown that polarization-independent modulation of Bessel beams is possible in paratellurite crystals; that is, the Bragg diffraction efficiency is independent of the polarization state of the incident beam. The physical reason for this kind of modulation is found to be the simultaneous occurrence of two anisotropic diffraction processes, such that the conditions for Bragg synchrony are satisfied for orthogonally polarized elliptical Bessel beams. The coupled wave equations and an overlap integral method are used to study the dependence of the diffraction efficiency on the length of the acousto-optical interaction, the ultrasonic power, and the polarization state of the incident Bessel beam.
