Fused Deposition modelling (FDM) technology is based on decomposition of 3-D computer models into thin cross sectional layers, followed by physically forming the layer and stacking them up layer by layer. FDM provide freedom to add material in the desired area and we are also able to create hollow region in certain portion of layer. In this way low weight with good strength single ply raw mater...

Oxidative fusion reactions of meso-phenoxazino Ni(ii) porphyrin were found to be temperature dependent, giving rise to either a doubly phenylene-fused product at room temperature or a singly phenoxazine-fused product at 70 °C. The latter was further oxidized to a doubly phenoxazine-fused Ni(ii) porphyrin, which was subsequently converted to the corresponding free base porphyrin and Zn(ii) porph...

Out of a total of 21 exencephalic p53-deficient embryonic and newborn mice, 6 (28.6%) possessed fused maxillary incisor teeth. On histological analysis of the 5 examples seen on day 19.5 of gestation and newborn mice, 3 varieties were observed: an example of 'simple' fusion, 3 examples of simple fusion each of which contained a 'dens in dente' ('tooth within a tooth'), and a single example in w...

In this paper, a novel core-modified porphyrin with meso-aryl substituents and phenanthrene-fused pyrrole rings (N2S2-OR) is synthesized. Scanning tunneling microscopy (STM) has been used to probe its self-assembly behavior on a highly-oriented pyrolytic graphite (HOPG) surface. Our STM results have shown that there is an obvious solvent-dependent self-assembly for the surface-confined target m...

An N-fused porphyrin rhenium complex was synthesized by the thermal reaction of an N-confused porphyrin with Re2(CO)10 and its structure was determined by X-ray crystallographic analysis.

A base-promoted one-pot tandem reaction sequence has been developed to transform electron-deficient chromone-fused dienes 1 and 1,3-dicarbonyl compounds 2 to functionalized 2-hydroxybenzophenones 3 under mild conditions. This domino process, which involves multiple reactions, including Michael addition/cyclization/elimination, serves as an efficient, economic, and eco-friendly method for the co...

Understanding the composition and structure of the acquired enamel pellicle (AEP) has been a major goal in oral biology. Our lab has conducted studies on the composition of AEP formed on permanent enamel. The exhaustive exploration has provided a comprehensive identification of more than 100 proteins from AEP formed on permanent enamel. The AEP formed on deciduous enamel has not been subjected ...

The genus Habrobathynella Schminke, 1973, presently contains 11 species: two species from Madagascar and nine from the peninsular India. Two new species of this genus, viz. H. ajraoi n. sp., and H. parakrishna n. sp., both collected in the phreatic waters of farm bores, and one new species of the same genus, H. pseudoindica n. sp., taken from the hyporheic zone of the River Krishna, are describ...

An extremely efficient catalytic protocol for the synthesis of spirooxindole derivatives via a one-pot three component approach in the presence of SBA-Oxime-Zn, as a heterogeneous catalyst using water as a green solvent is reported. The catalyst exhibited excellent catalytic activity, and the proposed methodology is capable of providing the desired products in good yield and short reaction time...
