Data for publication entitled: Silica-coated gold nanoshells. Surface chemistry, optical properties and stability
No full textResearch data that was used to create the publication entitled: Silica-coated gold nanoshells: Surface chemistry, optical properties and stability. Gordel-Wójcik Marta, Pietrzak Michał, Kołkowski Radosław, Zych Eugeniusz. Journal of Luminescence, 2024, 270, 120565/1-120565/9. DOI: 10.1016/j.jlumin.2024.120565This study provides a detailed investigation into the optical characteristics of colloidal gold nanoshells (NSs) with varying gold layer thicknesses and an additional silica coating. Our findings indicate that the spectral position of the localized plasmon resonance in NSs is highly sensitive to these parameters. Additionally, we observe that the silica layer plays a crucial role in enhancing the stability of colloidal systems. To complement our experimental results, we perform theoretical calculations that illustrate how absorption and scattering contribute to the overall extinction as a function of gold layer thickness. These calculations also shed light on the mechanisms behind spectral broadening in clustered NSs. Our results offer valuable insights for designing hybrid materials with applications in refractive-index sensing, metal-enhanced fluorescence (MEF), and surface-enhanced Raman scattering (SERS).Please consult the readme.txt file for additional information.</p
Date fruit textural features under freezing storage
No full textAn innovative approach based on image analysis was used to assess the external quality of fresh and frozen ‘Mejhoul’ and ‘Boufeggous’ date palm cultivars stored for 6 months at −10 °C and −18 °C. Their quality was evaluated, in a non-destructive manner, based on texture features extracted from images acquired using a digital camera and flatbed scanner.The whole process of image processing was carried out using MATLAB R2024a and Q-MAZDA 23.10 software. The extracted features are reported in the four datasets based on "image acquisition device", "date cultivar", and "Storage temperature".</p
Automated sequential SPME adressing the displacement effect in food samples
No full textThe research focuses on developing an automated sequential solid-phase microextraction (SPME) strategy to address the displacement effect in food samples, particularly for analyzing volatile compounds in beer. The study introduces a two-step extraction process using different SPME coatings to first remove high-affinity nonpolar compounds before extracting polar analytes, which improves extraction efficiency. This method, integrated with GC–MS analysis, eliminates the need for manual intervention, making it more practical for automated food analysis. The results show enhanced detection of polar compounds while maintaining quantification accuracy for nonpolar ones.Data contains a ReadMe.txt file.</p
The influence of HIV sense and antisense transcripts on stochastic HIV gene expression and reactivation
No full textIn this study, we established dozens of single provirus-infected cellular clones offering various transcriptional phenotypes of HIV. We proposed that stochastic fluctuations in HIV transcription can appear at, at least, two levels: (1) the chromosomal landscape and (2) the in situ HIV integration site. In the former case, proviruses integrating at different genomic locations demonstrated a variety of transcriptional bursting and can be classified in noise space constructed based on the parameters associated with the coefficient of variation and using a mathematical model fitting a curve of exponential decay. In the latter case, stochastic HIV transcription can be unveiled through its phenotypic bifurcation and tended to be a pure epigenetic phenomenon: the identical provirus demonstrated fluctuations in its transcription with an elevated frequency. We observed similar expression patterns between sense and antisense RNA transcripts. Notably, both HIV long terminal repeats reacted to drug stimulation and may reveal distinct behaviors. Overall, our data suggest that HIV antisense transcripts could be involved in the stochastic nature of HIV transcription.</p

Analiza opiera się na absorpcji energii przez elektrony w cząsteczkach, prowadząc do przejść elektronowych – głównie z orbitalu podstawowego (np. HOMO) na orbital wzbudzony (np. LUMO). Spektroskopia UV-Vis jest powszechnie stosowana do badania stężenia i degradacji barwników organicznych w roztworach wodnych.Charakteryzacja wiązań - spektroskopia FTIR (Fourier Transform Infrared Spectroscopy): to technika analityczna służąca do identyfikacji związków chemicznych oraz analizy struktury cząsteczkowej materiałów na podstawie ich charakterystycznych drgań molekularnych. Pomiar polega na rejestrowaniu widma pochłaniania promieniowania podczerwonego przez próbkę, co pozwala określić obecność określonych grup funkcyjnych. Metoda ta jest szeroko stosowana w inżynierii materiałowej do badania polimerów, kompozytów, nanomateriałów, cienkich warstw czy produktów degradacji chemicznej. Analiza FTIR pozwala m.in. na ocenę czystości materiału, identyfikację produktów reakcji chemicznych oraz monitorowanie zmian zachodzących w strukturze powierzchni w wyniku modyfikacji lub starzenia się próbki.Czystość materiału (XRF - fluorescencja rentgenowska): Technika ta została użyta do określenia czystości materiału MXenes poprzez analizę jego składu pierwiastkowego.
