Summary: The aim of this study was to evaluate the potential of Raman and FT-IR spectroscopies in predicting microbial beef spoilage indicators. Vacuum skin packaged beef steaks were stored at different temperatures, and spectroscopic data, as well as total viable count (TVC) and total volatile basic nitrogen (TVB-N) measurements, were collected during the storage period. PLSR models for TVC and TVB-N were developed and evaluated, showing RMSE values ranging from 0.81 to 1.59 (log CFU/g or mg/100 g) and determination coefficients (R2) ranging from 0.54 to 0.75. The performance of the PLSR model based on data fusion was better than that based on Raman spectra and similar to that based on FT-IR. Overall, Raman spectroscopy, FT-IR spectroscopy, and their combination showed potential in predicting beef spoilage.

Summary: The recycling of waste mandarin peels into biochar (MRBC) has been used as a high performance and cost-effective adsorbent for treating polluted wastewater effluents. Batch adsorption studies were conducted to analyze the adsorption competency of MRBC on two dyes, methylene blue (MB) and basic fuchsin (BF), either in individual solutions or binary combinations. The results showed that MRBC was capable of effectively removing a high percentage of both dyes. However, the adsorption capacity decreased when the dyes were combined. The cost estimation of MRBC production and wastewater treatment indicated that both were relatively low.

The introduction of Sb3+ effectively reduced the band gap of the host material and enabled energy transfer pathway for Tb3+ emission. The doped Tb3+ ions resulted in the suppression of emission due to electron transfer. The Cs2NaInCl6: 2.5 %Sb3+, 40 %Tb3+ NCs exhibited superior sensitivity and selectivity for copper ions detection.

Summary: Raman spectroscopy is commonly used for studying glassy materials in cultural heritage, but it is more difficult to interpret the spectra and apply the technique with portable instruments. In contrast, diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) can be used in archaeometric investigations as it is portable and non-invasive. However, there is limited application of this technique to historical glasses. This exploratory work demonstrates the potential of DRIFTS, in combination with portable X-ray Fluorescence (pXRF) and EDS microanalyses, for studying the composition and alteration of glass samples in cultural heritage.
