    Simulations of optimal light polarization state generators and analyzers configurations realized in one-way double pass Mueller polarimetric system using two twisted nematic liquid crystals working in the same way

    No full text
    The dataset contains the results of optimizing the configurations of light polarization state generators and analyzers that can be implemented in one-way double pass Mueller polarimetric system. The same module is used as a generator (PSG) and analyzer (PSA) of different polarization states of light. In the performed numerical simulations, the PSG/PSA module is constructed from a linear polarizer and two twisted nematic liquid crystals (TNLCs).PSG/PSA descriptionThe elements of the system are represented by a Mueller matrices. The forms of the used Mueller matrices are included in the file: &#34;Mueller_matrix.pdf&#34;. TNLCs are the same oriented azimuthally. It was assumed that for PSG, TNLC director axis of the first layer is aligned along the x-axis of the coordinate system. However, for PSA, TNLC director at the input surface of the modulator is rotated by an angle π/2. Due to the configuration, TNLCs in the PSG and PSA system introduce the same linear phases. The dependence between the voltage of the TNLC and the induced phase difference is not considered. Both TNLC elements are identical and at the same time introduce equal linear phase differences.Optimization processThe numerical PSG/PSA model were simulated and optimized to find the optimal set of TNLC’s linear phase differences for every linear polarizer’s azimuth angle, and thereby the best set of generators and analyzers, leading to the minimum system condition number (CN). Also equally weighted variance (EWV) is calculated. The results of optimization process were generated for:different ranges of possible TNLC’s linear phase difference: (0;2π&gt;, (0;3π&gt;, (0;4π&gt;, (0;5π&gt;,different number of configurations realized by PSG/PSA (n&#61;{4:20}),azimuthal orientations of the polarizer from 0°-180° with a step of 0.5°.For each azimuth angle of the polarizer randomly permuted n TNLC’s linear phases and determination instrumental matrices for PSG (the columns of this matrix correspond to the n Stokes vectors of the PSG) and PSA (the rows of this matrix correspond to the n Stokes vectors of the PSA). CN of the polarimeter system was calculated as product of generator’s CN and analyzer’s CN. These steps have been repeated 10 000 times and the minimum CN value corresponding to a given polarizer azimuth angle was determined. Associated with this determined minimum CN value of the system are EWV value and set of n TNLC’s linear phases, leading to n Stokes vectors for PSG and PSA.Used software: MATLAB File information and data formatThe data are saved as text files (.txt) and MAT-files (.mat).The resulting files are grouped according to the assumed maximum linear phase difference introduced by TNLC (PDmax):maximum_linear_phase_difference_2pi.zip -&gt; TNLC’s linear phases are generated from the range (0;2π&gt;maximum_linear_phase_difference_3pi.zip -&gt; TNLC’s linear phases are generated from the range (0;3π&gt;maximum_linear_phase_difference_4pi.zip -&gt; TNLC’s linear phases are generated from the range (0;4π&gt;maximum_linear_phase_difference_5pi.zip -&gt; TNLC’s linear phases are generated from the range (0;5π&gt;.Inside, the folders are grouped according to the different number of configurations (n&#61;{4:20}). Names are created in this way: number_of_configurations_n.Each folder contains:CN_PSA_vs_alfaP_PDmax_n.txt -&gt; The first row is the azimuth angles of the polarizer in radians, the second row is the CN values of the PSA instrumental matrix (corresponding to the minimum CN value of the system).CN_PSG_vs_alfaP_PDmax_n.txt -&gt; The first row is the azimuth angles of the polarizer in radians, the second row is the CN values of the PSG instrumental matrix (corresponding to the minimum CN value of the system).CN _vs_alfaP_PDmax_n.txt -&gt; The first row is the azimuth angles of the polarizer in radians, the second row is the minimum CN values of the system.EWV _vs_alfaP_PDmax_n.txt -&gt; The first row is the azimuth angles of the polarizer in radians, the second row is the EWV values of the system (corresponding to the minimum CN value of the system).linear_phase _alfaP_PDmax_n.txt -&gt; The first row is the azimuth angles of the polarizer in radians, the second row is the set of n TNLC’s linear phases in radians (corresponding to the minimum CN value of the system).PSA_vs_alfaP_PDmax_n.mat -&gt; For each azimuth angle of the polarizer saved matrix formed from the Stokes vectors of the analyzers (corresponding to the minimum CN value of the system). Each column is a new Stokes vector.PSG_vs_alfaP_PDmax_n.mat -&gt; For each azimuth angle of the polarizer saved matrix formed from the Stokes vectors of the generators (corresponding to the minimum CN value of the system).

    Data related to the work entitled Spectroscopic studies under properties of chlorpromazine conjugated to gold nanoparticles

    No full text
    Our research focuses on developing synthesis techniques for conjugating chlorpromazine (CPZ), a neuroleptic drug, with gold nanoparticles (AuNPs). The CPZ-AuNP conjugates were synthesized via a ligand exchange reaction on quasi-spherical, negatively charged citrate-stabilized TC-AuNPs, averaging 55 ± 5 nm in diameter. UV–vis spectroscopy was used to assess the stability of the conjugates under varying pH levels and ionic strengths. Electrokinetic measurements revealed that the zeta potential of the CPZ-AuNP conjugates is highly dependent on the amount of CPZ adsorbed onto the nanoparticle surface. Notably, the conjugates displayed an isoelectric point at pH 8.8. To investigate the adsorption structure of CPZ on the TC-AuNPs, surface-enhanced Raman spectroscopy (SERS) and surface-enhanced infrared absorption spectroscopy (SEIRA) were utilized. Spectral interpretation was supported by Raman and FTIR data for CPZ, as well as Density Functional Theory (DFT) calculations. The findings suggest that CPZ binds to the nanoparticle surface primarily through the phenothiazine ring and propylene bridge, both oriented at an angle. Moreover, the C-N-C fragment was found to interact with the TC-AuNP surface in a perpendicular orientation. </p

    Tourist Perceptions of Crowding and Satisfaction (2023)

    No full text
    The data for this study were collected in the summer of 2023 in three European capitals: London, Paris, and Rome. The data collection process was based on the Computer-Assisted Personal Interviewing (CAPI) method, which involves computer-assisted direct interviews. Surveys were conducted in key tourist locations in each city to obtain a representative sample of tourists. A total of 1,859 respondents participated in the study, with half being domestic tourists and the other half international tourists. The questionnaire was prepared in English and translated into four other languages. It was then verified by members of the research team and native speakers to ensure maximum clarity and comprehensibility of the statements. The choice of the CAPI technique enabled the collection of high-quality data by increasing the response rate, minimizing errors resulting from misinterpretation of questions, and eliminating missing responses. The collected data covered a wide range of variables, including perception of crowding in tourist spaces, destination attractiveness, travel satisfaction, and tourist loyalty. Additionally, various forms of mobility were considered, such as public transport, active mobility (walking, cycling), and micromobility. The data were subjected to statistical analysis using Partial Least Squares Structural Equation Modeling (PLS-SEM) and multi-group analysis, allowing for the identification of key factors influencing tourists&#39; perceptions in different urban conditions.</p

    Dispersive solid phase extraction of antisense oligonucleotides with the use of amino acid based adsorbents

    No full text
    Data have been deposited on the development of a method of dispersive solid-phase extraction of antisense oligonucleotides using adsorbents modified with amino acid molecules. The impact of the composition of solvents used for adsorption and desorption was tested (pH, salt type, salt concentration, organic solvent type, and content in the solution). All tested adsorbents allowed for the efficient recovery of oligonucleotides. Nevertheless, adsorbent with bonded methionine showed the highest efficiency, probably due to the presence of a sulfur atom. The recovery depended on the structure of the antisense oligonucleotide. It was higher for shorter oligonucleotides and modified ones (phosphorothioate, 2′-O-methyl, 2′-O-(2-methoxyethyl) and both phosphorothioate and 2′-O-methyl in one oligonucleotide). The results revealed that the recovery also increases with increasing hydrophobicity of the modification. Data on the characteristics of the synthesized adsorbents, kinetics of oligonucleotide adsorption, sorption capacity were also deposited. Moreover, the results of applying the developed extraction method to human plasma samples are also included.</p
