Benzopyrano-Fused Phenanthridine-Based Columnar Mesogens: Synthesis, Self-organization and Charge-Transport Properties.

Columnar mesogens constitute a fascinating class of supramolecular nano-architectures owing to the exceptional properties induced by their self-assembling behavior. Extending the π-conjugated core in such systems by incorporating heteroatoms extensively influences their mesomorphic, photophysical properties, etc., presenting them as potential candidates for optoelectronic applications.

New luminescent ordered liquid crystalline molecules with a 3-cyano-2-pyridone core unit.

The self-organized states of liquid crystals (LCs) have recently received a lot of attention because of their various applications, especially in the fields of electron transport materials and optoelectronic devices. In most of these applications, molecules containing a donor-acceptor skeleton have been widely employed and generally these molecular frameworks have been designed mainly on the basis of the donor-acceptor concept. Inspired from this concept, we synthesized a series of new donor-acceptor based luminescent molecules, 4,6-bis(4-alkyloxyphenyl)-2-oxo-1,2-dihydropyridine-3-carbonitrile (Pn-series), carrying variable alkoxy chains [ = 8, 10, 12, 14, 16].

Investigation of embelin synthetic hybrids as potential COVID-19 and COX inhibitors: Synthesis, spectral analysis, DFT calculations and molecular docking studies.

Embelin (2, 5-dihydroxy-3-undecyl-1,4-benzoquinone), a benzoquinone isolated from fruits of Embelia ribes has miscellaneous biological potentials including; anticancer, anti-inflammation, antibiotic, and anti-hyperglycemic activities. Also, embelin down-regulates the overexpression of inflammatory pathways like NF-kB, TACE, TNF-α, and other cytokines. Furthermore, embelin fascinated synthetic interest as a pharmacologically active compound.

Development of rice analogues fortified with iron, folic acid and Vitamin A.

Fortified rice analogues were developed utilising the broken-rice fortified with selected micronutrients like iron, folic acid and Vitamin A. The purpose of this study was to investigate the feasibility of fortifying rice analogues with micronutrients and retention after extrusion and cooking. Cold extruder operated at 55 rpm screw speed and 1.

Development of rice analogues using by-products of rice and dhal mills.

Development process of rice analogues by utilising the broken rice (BRF) and broken pigeonpea dhal (BPDF) flours together with water and sodium alginate as binding agent through extrusion was carried out. Two variable viz, BPDF (20, 30 and 40%) and moisture content (25, 30 and 35%) were controlled in the study to produce rice analogue resembling the raw rice. The optimum combination of flour mixture established for 30% BPDF and 30% water content with highest desirability of 0.
