Vanadium exhibits formal oxidation states from +V down to —III. The most stable oxidation states +IV and +V under normal conditions are generally stabilized through V-O bond and oxocations [VO]2+, [VO]3+ and [V02]+ are ...
Through historical contributions by Oparin, Haldane, Miller, Urey, Cairns-Smith etc., the intellectual challenge of the origin of life enigma has unfolded that life originated on Earth through a series of physicochemical ...
Fresh water is an important and essential component of this universe and plays a vital role in the proper functioning of the Earth's ecosystem. In spite of this, safe drinking water is not available in many parts of the ...
Biosurfactants are amphipathic compounds possessing both hydrophilic and hydrophobic moieties that partition preferentially at the interface between two different phases in a heterogeneous system. In past two decades, these ...
During the transformation of organic waste in composting process, different groups of carbohydrate such as OH, CH2, CH3 converted into carboxylic (COOH), C=O conjugated, esters (COOC) and C=C groups of aromatic acids. ...
Vanadium was named after Vanadis, the most aristocratic of Scandinavian
goddess, who symbolizes beauty and fertility - essential features of vanadium
chemistry. Vanadium may be beneficial and possibly essential in humans, ...
Rapid industrialization and urbanization has no doubt improved the quality oflife.
However its adverse effects are severe pollution of air, water and soil due to mobilization
of several harmful metals and organic pollutants ...
Polycyclic aromatic hydrocarbons (PAHs) such as anthracene, fluorene, pyrene,
perylene, triphenylene, fluoranthene, benzo[&]fluoranthene, pentacene, and their derivatives
have received immense attention as building blocks ...
Environmental pollution is a major global problem posing serious risk to man and
animals. It is defined as the human alteration of chemical or physical characteristics of the
environment to a degree that is harmful to ...
Lanthanides are termed rare-earth elements; they are not rare in nature because their
levels in the earth's crust are often equal to or higher than those of some physiologically
significant elements. Although the members ...
The thesis entitled "Sugar-based Organocatalysts and Chiral Salen Complexes for Enantio
selective Synthesis" has been divided into five chapters.
The title of the thesis reflects our objective observably, which includes ...
Several experiments have been conducted to trace out possible steps of chemical evolution.
Experimental results suggest that origin of life processes began with the formation of
important biomonomers, such as amino acids ...
Copper and zinc both are important metal ions in the biology and have interesting
coordination chemistry. Copper and zinc both possess stable 2+ oxidation state and
analogous complexes of zinc in several times help to ...
Chirality has emerged as a key issue in drug design, discovery and development
as stereoisomer discrimination plays a significant role in many pharmacological events.
Usually the desired pharmacological activity resides ...
Catalysts have played key role in the development of modern chemical
technologies. They activate the chemical reaction at milder conditions through the
bonding of reactant molecules with definite functional groups called ...
The thesis entitled "Asymmetric Synthesis Mediated by Novel Organocatalysts and Reactions
of 2-Alkenyl-p-benzoquinones" is divided into five chapters.
Novel Camphor-based prolinamides have been synthesized and employed ...
Rearrangement reactions play an important role in organic and Biochemistry
and are very interesting instance of unimolecular reactions. These reactions play a
significant role in biological system. The beauty of rearrangement ...
Copper is physiologically bioessential element required for the growth and
survival ofmany living organism. Mono, di and multinuclear copper complexes are used
to mimics the synthetic models of the active sites of many ...
The field of macrocyclic chemistry has undergone enormous expansion during
the past few decades. A macrocycle is defined as a cyclic compound with nine or
more atoms (including all hetero atoms) in the ring along with ...
Nanoscale materials deal with structures, devices, and systems that have novel
physicochemical properties and functions due to their small size. Nanoscale materials are
generally considered as the materials consisting ...
