Summary: A novel fluorogenic sensor BTMPD was synthesized and characterized by spectroscopic methods. The sensor showed high selectivity, sensitivity, and low detection limit for the sensing of amino acid Serine. The detection range was linear and the detection limit was found to be 1.74+/- 0.02 nM under optimal conditions. The theoretical calculations using DFT provided information about the system arrangement and features, which was in good agreement with experimental results. The practical applicability of BTMPD in fluorescence sensing and real sample analysis was demonstrated.

Summary: A new hexadentate redox-active schiff base ligand reacted with Ni-II(O2CCH3)(2)center dot 4H(2)O and PdCl2 to form yellow and red crystalline solids. Cyclic voltammetry showed three reversible responses for compound 1 and one for compound 2. Structural analysis revealed that compound 1 is discrete mononuclear and compound 2 is discrete dinuclear coordination complex. DFT calculations and Time-dependent-DFT calculations provided information about the electronic structures and spectral absorptions of the compounds.

Summary: This review focuses on novel and advanced techniques for lignocellulosic biomass pretreatment in bio-H2 production, including physical, chemical, physico-chemical, microbiological, and nanotechnology-based methods. The objective is to understand the impact of lignocellulosic biomass pretreatment on bio-H2 production and positive findings. The influence of different pretreatment techniques on biomass structure, particularly cellulose digestibility and the generation of inhibitory compounds, is discussed. The findings suggest that stepwise pretreatment is crucial for successful bio-H2 production, although cost-effective large-scale conversion of lignocellulosic biomass into fermentable sugars with low inhibitory concentration remains a challenge.

Summary: The study investigates the health risks associated with toxic uranium contamination in the drinking water of Thoothukudi district. The analysis of water samples collected during pre- and post-monsoon seasons reveals a wide range of uranium concentrations. Geochemical modeling studies suggest that the uraninite mineral is under saturated conditions, leading to the distribution of the least soluble U4O9 mineral species. Statistical analysis indicates that the use of nitrogen and phosphate fertilizers may contribute to the dissolution of uranium minerals, resulting in elevated uranium levels in the water samples. The calculated noncarcinogenic risk falls within acceptable limits, indicating that chemical toxicity is a greater concern than the carcinogenic risk.

Summary: The present research focuses on determining the sources and concentration of uranium in groundwater from the hard rock aquifer. Analysis of 254 groundwater samples shows uranium concentrations ranging from 0.5 to 113 ppb (pre-monsoon) and 0.5 to 120 ppb (post-monsoon). The study suggests that the low uranium concentrations in the region may be attributed to poor mineral dissolution in the subsurface. The dominant distribution of U4O9 mineral confirms the undersaturation of Uraninite during both seasons. Several samples with high uranium concentrations may be due to fertilizer usage in agricultural activities. The use of GIS technique helps identify uranium-contaminated locations and water quality parameters.

Summary: The study analyzed the quality of groundwater and uranium in the Tirunelveli district. The results show that the uranium concentration in the samples ranged from 0.5 to 65 ppb (pre-monsoon) and 0.5-52 ppb (post-monsoon), with most samples falling within the permissible limits for both radiological and chemical toxicity. Geochemical modeling suggests that the lower uranium concentration may be due to the limited dissolution of uranium with the predominant species of U4O9. The spatial distribution map highlights the regions where uranium and other water quality parameters are polluted.

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.

Summary: This study synthesized Cs2NaInCl6 nanocrystals co-doped with Sb3+ and Tb3+ ions as probes for copper ions detection in lubricating oil. 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.
