Herein, we have developed a series of isostructural mixed Ln(3+)-4-(dipyridin-2-yl)aminobenzoate coordination polymers [Ln(3+) = Eu(3+) (1), Tb(3+) (2), and Gd(3+) (3)], and characterized and investigated their photophysical properties. The results demonstrated that by gently tuning the excitation wavelength of these mixed lanthanide complexes, white light(More)
AIM Development of highly sensitive diagnostic nanoprobe for cancer imaging based on surface-enhanced Raman scattering (SERS) platform. MATERIALS & METHODS Synthesis of novel squaraine dyes as a Raman signature molecule denoted as lipoic-squaraine-lipoic (LSL), propyl-squaraine-lipoic (PSL) and propyl-squaraine-propyl (PSP). The SERS-nanotag constructed(More)
Three new binuclear lanthanide complexes of general formula [Ln(2)(L)(6)(H(2)O)(4)] (Ln = Tb (1), Eu (2), and Gd (3)) supported by the novel aromatic carboxylate ligand 4-(dibenzylamino)benzoic acid (HL) have been synthesized. Complexes 1 and 2 were structurally characterized by single-crystal X-ray diffraction. Both 1 and 2 crystallize in the triclinic(More)
We screened soil samples collected from underneath shrubs and/or large trees at different locations in the Eastern Ghats of Andhra Pradesh for xylanase-producing microorganisms. Xylose-utilizing bacteria were numerically dominant in soils of most locations whereas xylose- and xylan-utilizing actinobacteria were minor components. Xylan-utilizing fungi(More)
In this paper an image resolution and contrast enhancement technique for Additive White Gaussian Noise (AWGN) removal is verified aiming high resolution and contrast image output. In image resolution enhancement, the main loss is on its high frequency components (i.e., edges), which is due to the smoothing caused by interpolation. In order to increase the(More)
Herein, a new aromatic carboxylate ligand, namely, 4-(dipyridin-2-yl)aminobenzoic acid (HL), has been designed and employed for the construction of a series of lanthanide complexes (Eu(3+) = 1, Tb(3+) = 2, and Gd(3+) = 3). Complexes of 1 and 2 were structurally authenticated by single-crystal X-ray diffraction and were found to exist as infinite 1D(More)
