Adverse influences of mercury on living organisms are well known. Despite efforts from various regulatory agencies, the build-up Hg<sup>2+</sup> concentration in environment is serious concern. This necessitates search for new and efficient reagents recognition detection environmental samples.
A unique example of an ESIPT coupled AIEE process, associated with a single molecule (1), is utilized for generating multiple luminescent colors (blue-green-white-yellow). The J-aggregated state 1 forms gel in THF and this property retained even the solid state.
A new cell membrane permeable reagent for detection of endogenous Cys as well quantitative estimation and His in a human blood plasma sample.
Two-photon imaging of endogenous bisulphite ions the hippocampus region mouse brain.
A new 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY)-based probe molecule (L) is synthesized for specific binding to Hg2+ ion in physiological condition with an associated luminescence ON response the near-IR region of spectrum. Appropriate functionalization 5-position each two pyrrole moieties styryl functionality a BODIPY core helped us achieving extended conjugation and facile intramolecular charge transfer transition narrow energy gap frontier orbitals. This accounted poor emission...
Complexes synthesized from Zn(II), Cu(II), and Cd(II), using a dipicolyl amine derivative (L), showed unique specificity toward pyrophosphate ion (PPi or P4O74–) among all other common anionic analytes, including different biologically significant phosphate (PO43–, H2PO42–) phosphate-ion-based nucleotides, such as AMP, ADP, ATP, CTP. However, the relative affinities of PPi these three metal complexes were found to vary follow order KaL.Zn–PPi > are given in units aL.Cu–PPi ≥ KaL.Cd–PPi....
Mitigating potentially toxic elements (PTEs) contamination in post-mining land is essential for restoring the environmental health of post mining ecosystems. A comprehensive understanding how topography and vegetation impact PTEs distribution can help devise targeted reclamation strategies to reduce toxicity.This study investigated influence topographical regions a overburden heap (top, middle, bottom) selected tree species (Azadirachta indica, Senna siamea, Leucaena leucocephala) on total...
A dithiane derivative of BODIPY is synthesized. This new reagent could be used for the specific and instantaneous detection Hg2+ in physiological condition. reacts specifically with to regenerate parent BODIPY-aldehyde consequential change visually detectable optical responses this provides possibility using as a colorimetric probe or fluorescent biomarker/imaging reagent. Further, non-covalent interactions utilized formation an inclusion complex biologically benign β-cyclodextrin enhancing...
A chemodosimetric reagent for specific detection of cyanide species and its possible use in imaging applications as well assay development important enzymes.
Critical rare earth elements are enriched in the >250 μm size fraction of ash with an outlook coefficient > 2.0. Co-extraction alumina is advantageous. Ash disposal policies should explore fractions to preserve fractions.
Two new reagents, having similar spatial arrangements for hydrogen atoms of the active methylene functionalities, were synthesized and interactions such reagents with different anionic analytes studied using electronic spectroscopy as well by 1H 31P NMR spectroscopic methods. Experimental studies revealed that these two showed preference binding to F– OAc–. Detailed theoretical along above-mentioned carried out understand contribution positively charged phosphonium ion, functionality, in...
Chemodosimetric reagent for quantification of cystathionine-γ-synthase and mapping endogenous biothiols with luminescence ON response.
Coal and lignite ash are emerging as significant sources for extracting rare earth elements (REEs) critical minerals. Despite lower concentrations of in ashes, their preconcentration is crucial enhancing extraction efficiency reducing energy consumption. Additionally, the simultaneous base metals could render combustion residue a more appealing raw material alongside elements. Lignite fly samples from Neyveli, India, were analyzed using physical separation methods to preconcentrate The total...
Re-vegetation or natural succession of plant species is an important factor soil development in postmining dumps. As the parent material (sedimentary rocks and regolith) more less uniform dump, topographic position vegetation are major factors that affects mine quality. Accordingly, this study was designed for a relative evaluation influence dump location (upper, middle, bottom) tree (A indica, L leucocephala, C siamea) on Trees growing bottom zones dumps were significantly taller with...
The combustion residues derived from coal, lignite, biomass, and spent wash could be recycled for the extraction of critical elements. Lignite ash, rich in Ca Si, holds promise scandium due to its comparable content (31 mg/kg) with conventional sources (50 mg/kg). Coal dominated by Si Al, contains appreciable Ga (44.8 a favorable rare earth element outlook coefficient (1.67).
