Studies on soil quality of mangrove forests would be of immense use in minimizing soil degradation and in adopting strategies for soil management at degraded sites. Among the various parameters of soil quality, biological and biochemical soil properties are very sensitive to environmental stress and provide rapid and accurate estimates on changes in quality(More)
How solvent conditions such as solvent polarity and hydrogen-bonding affect the fluorescence of a newly synthesized 3-pyrazolyl 2-pyrazoline derivative (Pyz) having pharmaceutical activity has been explored. The solvatochromic effect of Pyz is due to a change in dipole moment of the compound in the excited state. The relaxation of S1 state is perturbed in(More)
The photophysical behavior of 3-pyrazolyl-2-pyrazoline derivative (PZ), a newly synthesized biologically active compound has been studied in micellar solutions of anionic sodium dodecyl sulfate (SDS), cationic cetyl trimethylammonium bromide (CTAB) and nonionic p- tert-octylphenoxy polyoxyethanol (Triton X-100, TX-100) micelle using steady state and(More)
In the present investigation, an attempt has been made to study the interaction of newly synthesized bioactive compound 3-pyrazolyl 2-pyrazoline (PZ) with model transport proteins, bovine serum albumin (BSA), and human serum albumin (HSA) employing steady state and time-resolved fluorescence technique. We have focused on fluorescence resonance energy(More)
Spectroscopic studies of newly synthesized bioactive compound 2-(2-bromo-ethyl)-6-nitro-benzo[de]isoquinolene-1,3-dione (BNBIO) have been carried out in polar aprotic solvent, viz. acetonitrile, tetrahydrofuran, 1,4-dioxan, ethylene glycol, dimethyl formamide, and polar protic solvent, viz. methanol, ethanol, propanol, water. Variation in absorbance of(More)
Prussian Blue (PB) nanomolecular aggregates were prepared in a well-characterized, monodispersed biomimicking nanocavities formed by Aerosol OT (AOT) reverse micelle in H2O/AOT/heptane at different omega ([H2O]/[Surfactant]) employing coprecipitation technique. The formed nanomolecular aggregates of PB have been characterized by the UV-visible, Fourier(More)
Polycrystalline lanthanum oxalate (LaOX) nanorods (NRs) were succesfully synthesized using reverse micellar (RM) method. The study espouses the versatility of the reverse micellar method forming monodisperse, stable nanorods at room temperature. The as-synthesized LaOX nanorods were characterised by different techniques. Result shows that the nanorods of(More)
