Under hydrothermal condition, the decomposition of methanesulfonic acid to sulfate anion is observed, resulting in the formation of a novel thorium sulfate fluoride compound ThF2(SO4)(H2O) (1). This complex is structurally characterized by single crystal X-ray diffraction, revealing a three-dimensional structure crystallized in the monoclinic space-group P2(1)/n, where thorium cation is nine coordinated by four SO42- oxygen atoms, four bridging F-, and one H2O molecule. The crystal lattice parameters are a = 6.9065(7) angstrom, b = 6.9256(7) angstrom, c = 10.5892(11) angstrom, beta = 96.755(2)degrees, V 502.98(9) angstrom(3), Z = 4. The temperature dependent UV-Vis-NIR absorption spectra and fluorescence spectra were collected from 77 K to 300 K, where the intensities of the peaks varied as a function of temperature. The Raman vibrational spectrum of the samples collected from 100 to 2000 cm(-1) shows identical SO42- vibration modes. (C) 2015 Elsevier B.V. All rights reserved.

Summary: Highly sensitive detection of ultraviolet (UV) radiation is crucial in scientific research, chemical industries, and health-related applications. Traditional UV photodetectors have limitations in manufacturing procedures and obtaining accurate readouts. Thus, the search for new materials or simple strategies to develop UV dosimeters for quantitative, accurate, and on-site detection of UV radiation dose is highly desired. In this study, a photochromic uranyl-based coordination polymer was synthesized and a colorimetric dosimeter based on red-green-blue (RGB) parameters was developed. The mechanism of radical-induced photochromism was investigated, and the dosimeter was incorporated into an optoelectronic device for convenient, quantitative, and on-site detection of UV radiation dose.

Techno-economic assessment of waste mandarin biochar as a green adsorbent for binary dye wastewater effluents of methylene blue and basic fuchsin: Lab- and large-scale investigations

Ahmed S. El-Shafie, Evana Rahman, Yasser Gadelhak, Rehab Mahmoud, Marwa El-Azary

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.

Non-invasive analysis of reference glass and historical mosaic tesserae by means of reflectance infrared spectroscopy

Maria Cristina Caggiani, Germana Barone, Paolo Mazzoleni

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.
