Raw bananas (not including the peel) are 75% water, 23% carbohydrates, 1% protein, and contain negligible fat. Banana fiber is used in the production of banana paper. The leaves contain apiin which is used to make nanoparticle products. Apiin is a natural flavonoid, a diglycoside of the flavone apigenin found in banana leaf. Present paper deals with determination of pH of Banana Leaf ash, Banana fruit powder and Banana Peel powder; determination of CaO content in a Banana Leaf Ash; determination of Ascorbic acid from Banana fruit powder and Banana peel powder. FTIR spectra of Banana Leaf Ash, Banana fruit powder, Banana Peel Powder, 1% solution of Banana Leaf Ash, Banana fruit powder, Banana Peel Powder was obtained at room temperature by using an FTIR Spectrophotometer - Shimadzu - IR Affinity – 1. The spectra are collected in range from 350 - 4700 cm-1. Morphological graphs of the 1 % solution of Banana Leaf Ash, Banana fruit powder, Banana Peel Powder is provided by scanning electron microscopy (Digital Scanning Electron Microscope - JSM 6100 - JEOL) with a Link analytical system operating at 10 KV (acceleration voltage).<#LINE#>Edwards, G.

The longitudinal and transverse ultrasonic velocities were measured at 10 MHz using the overlapped pulse echo approach at room temperature. Evaluations of various parameters such as molar volume, Poisson's ratio, acoustic impedance, microhardness, Debye temperature and thermal expansion coefficient have been calculated by using the measured values of density, velocity, and elastic constants. Changes in the glass network's structure with compositions are examined in relation to these parameter alterations. Using XRD and SEM, the amorphous nature and morphology of the glass samples are examined. The functional groups were identified in the glass samples by using the FTIR analysis.<#LINE#>Gowda, V.

Formation constants of chelates at 35±10C and at constant ionic strength 0.1M NaNO3 have been calculated using Stability Constants of Generalized Species (SCOGS) computer program. The graph and speciation equilibria were elucidated with the help of ORGIN 6.1. Solution of di positive transition metal ions copper, nickel, zinc, cobalt (0.01M) were processed and standardized by complexometric titration Pyrimidine  base derivative (methyl thiouracil) 0.01M solution was prepared by dissolving the ligand into one equivalent of alkali sodium hydroxide (NaOH). Whereas solution of amino acid alanine (0.01M) were prepared in double distilled water only. The molar ratio of metal and ligand endeavoured was kept 1:1:1 for ternary mixture and 1:1:1:1 for quaternary mixtures. Multinuclear chelates understudy demonstrate the formation of multimetal-multiligand complexes of stoichiometry M1M2L1L2 in addition to ML1L2, ML1 and ML2 complexes for all metal ions. The pH titration curves, species distribution curves, hydroxo complex species and overall stability order found for heterobinuclear chelates are discussed in terms of Irving-Williams order. Solution structures of metal complexes with said ligands have been compared and discussed.<#LINE#>Nunn, P. B., Bell, E. A., Watson, A. A., & Nash, R. J.

The heavy metal and isocyanate content of both paints and primers were analyzed using Atomic Absorption Spectroscopy (AAS) and Gas Chromatography-Mass Spectrometry methods respectively. The analysis revealed that manganese and chromium concentrations in some paint samples exceeded permissible limits, while lead levels were significantly higher than the European Union's (EU) safety threshold. Conversely, cadmium, mercury, aluminium, copper, iron, nickel, arsenic, and cobalt were within acceptable regulatory limits. In primers, zinc concentrations were found to be above the EU limit, whereas other heavy metals remained below recommended levels. Additionally, all analyzed paint and primer samples contained isocyanate concentrations far exceeding the Occupational Safety and Health Administration (OSHA) exposure limit of 0.02 ppm, posing potential health risks to workers. These findings underscore the need for regulatory oversight, the adoption of safer alternatives, and enhanced protective measures to mitigate health hazards associated with automobile spray painting.<#LINE#>Der-Jen, H., Shun-Hui, C., Jie-Feng, D., Hui-Chung, S., Hong-Bin, C. & Yeh-Chung, C.

The physicochemical behaviour of dilutions of acidum phosphoricum have been investigated from the measurements of densities, , ultrasonic speeds, u and viscosities,  of pure ethanol control and 33dilutions of acidum phosphoricum of potencies ranging from 1C to 200C (with intervals of 2C up to 30C and then with intervals of 10 C up to 200 C) at six different temperatures and atmospheric pressure. From the experimental data, a number of physicochemical parameters, viz., the isentropic compressibilities, s, intermolecular free length, Lf, acoustic impedance, Z, relative association, RA, deviations in isentropic compressibility, s, deviations in intermolecular free length, Lf, deviations in acoustic impedance, Z and deviations in viscosity,  have been evaluated. These parameters show anomalous behaviour at certain potencies, viz., 1C, 6C, 8C, 12C, 22C, 70C, 80C, 100C, 120C and 170C to 180C, of these homoeopathic dilutions. The results have been qualitatively discussed in terms of interactions between H+/phosphate ions and dissipative structures of ethanol-water molecules in these acidum phosphoricum dilutions. The results indicated that that even in extreme dilutions the molecules of acidum phosphoricum may be present in these homoeopathic dilutions.<#LINE#>Chikramane P. S., Suresh A. K., Bellare J.

This concerning situation necessitates a diagnostic study to establish an integrated and sustainable water resource management plan for the zone. The objective of this work is to evaluate the physico-chemical and bacteriological qualities of the zone's water. Water samples were collected and analyzed in triplicate, following standard analytical techniques outlined by Rodier. Static water levels in wells or boreholes were measured using a piezometric probe. Finally, the overall water quality was determined using the SEQ-Eau system (2003). The piezometric study indicated a deep water table, located at a minimum depth of 48 meters. Physically, the groundwater exhibits a relatively acidic pH range (5.4–7.4). Recorded temperatures ranged from 27.2°C to 35.6°C. Turbidity values for groundwater were below 5 NTU, while surface water turbidity ranged from 36 to 75 NTU. Electrical conductivity was low, with values ranging from 58 to 342 µS/cm. Chemically, the concentrations of ions and compounds such as nitrate, nitrite, total nitrogen, chloride, calcium, magnesium, COD, DBO5, and trace metals (As, Cd, Cu, Zn, Hg, Ni, Pb) in the water samples were generally low and below current regulations. Based on the SEQ-Eau (2003) surface water assessment framework, the ZES's surface waters generally exhibit excellent quality for most parameters, with the exception of dissolved oxygen and fecal coliforms, which showed poor to very poor classifications. Ongoing monitoring of these parameters is recommended during the operational phase of the ZES.<#LINE#>Dekhil, S. W.

Cucurbita maxima peel contains carotenes and Curcuma Longa rhizomes contain curcumin as natural pigments. Curcumin has numerous health benefits such as antioxidant, anti-inflammatory, anti-diabetic, immune boosting capacity, anti-cancer activities etc. Curcumin is a bioactive compound, and it has strong medicinal properties. Carotenes have different biological roles like strong antioxidant properties, helps in maintaining proper vision and good skin health, support in improving immune function, etc. Curcumin and carotenes are used as natural dye in fabrics and food materials. This study mainly focused on the extraction of natural pigments from peel of Cucurbita maxima and rhizome of Curcuma longa using an ultrasonic extraction technique. Cucurbita maxima peel contained significant amount of carotenoids. The principle-coloured component in dyestuff extracted from pumpkin peel is β-carotene. Extraction was done by using sunflower oil as green solvent. The extracted pigment was analysed by FTIR and UV Visible Spectroscopy.<#LINE#>Sarma, B., & Goswami, B. C.

In general, iron may be present in these effluents due to the use of iron-based mordants in dyeing processes or as impurities in the dyes themselves. Additionally, iron can also enter the effluents from equipments corrosion or from water sources used in the dyeing process. To determine the exact amount of iron in a specific dyeing industrial effluent, it is required to conduct a comprehensive analysis through different chemical and instrumental methods or other suitable analytical techniques. These analyses would provide precise measurements of the concentration of iron in the effluent.<#LINE#>Moore S. B., & Ausley, L. W.

The present investigation deals with the theoretical estimation of viscosity of two binary liquid mixtures of 2-Propenol and 2-Phenylehanol or Benzyl alcohol over the entire range of mole fractions at elevated temperatures from 298.15-318.15K and atmospheric pressure by six empirical relations such as Eyring, Bingham, Kendall-Munroe, Frenkel, Dey and Hind. Computed values of viscosities obtained by the aforementioned relations were compared with the experimental findings. Deviation in viscosity ( ∆η ) was derived from measured data and fitted to redlich-kister polynomial to estimate the binary coefficient and standard deviation. Excess molar volume (VE) was also computed to analyze the extent of molecular interactions and Furthermore, Joubyan Acree model is used to correlate the experimental findings. Eyring, Hind, and Frenkel models show the best agreement with experimental data.<#LINE#>Domańska, U., & Laskowska, M.
