The work presented in this thesis is focused on the thermal, kinetic and morphological
studies of various pyrotechnic/propellant compositions and their ingredients. A lot of
research work has been carried out in the field ...
Ablatives are materials used to protect the inner hardware of aerospace structures
from the inimical temperature and shear environments. Fifty six diverse compositions have
been used with numerous incorporations (MWCNTs, ...
The thesis describes research study on the mechanical and viscoelastic properties of the polyurethanes (PU). Both natural precursor i.e. castor oil and synthetic HTPB based polyurethane systems respectively were studied. ...
Hydroxyapatite (HA) is similar to the mineral part of human calcified tissues and
therefore has a wide range of applications like treatment of bone defects in the form of
powder; and as coatings on metallic implants for ...
This thesis provides an insight to resonant waveguide gratings (RWGs) and
thermo-optic coefficients (TOCs) accompanying various organic and inorganic materials.
The RWGs structures were designed by Fourier Modal Method ...
Organic photovoltaic (OPV) devices are the focus of research among
the other photovoltaic devices due to various advantages like their low
cost, versatility of the materials used in terms of tunability of their electrical ...
The dissertation reports the efficiency of the nanofillers to attenuate thermal insulation, thermal transition, thermal stability, and mechanical characteristics of the elastomeric nanocomposites. Twenty eight diverse ...
The effect of copper, cadmium, cobalt and lithium substitution on the Mn-Zn ferrites has been
investigated. Four series of spinel nano ferrites with nominal compositions Mn0.5CuxZn0.5-xFe2O4
(0.0 ≤ x ≤ 0.35), ...
Enhanced effectiveness of pharmaceuticals and agrochemicals is the most sought-after
attribute in the field of enantioselective synthesis of chiral molecules where single enantiomer
(R or S) is required, for which ...
Dye sensitized solar cells (DSSCs) being third generation photovoltaics are
inexpensive renewable energy resource and recently been a hot topic of research.
The objective of the present research work was to develop ...
Carbon dioxide (CO2) capture from the environment or other gas mixtures is extremely
imperative to reduce the global warming. CO2 gas is acidic in nature and can adversely
affect the earth atmosphere by enhancing its ...

Aluminum/carbon nanotubes (Al-CNTs) composite is an encouraging candidate material for aerospace applications due to its expected high strength-to-weight ratio. Carbon nanotubes (CNTs) offer remarkable reinforcements owing ...
It is a well known fact that aramid fibres exhibit poor adhesion with most
matrices, and many research efforts have been devoted to improve this adhesion. A
novel chemical treatment has been developed in this thesis for ...
Performance of a solid propulsion system is based on reliable working of the propellant stored in the system. The performance of composite propellant is a strong function of its mechanical and ballistic properties. There ...
Objective of this work was to develop a processing protocol to develop devices with Hole Transport Layer (HTL) free architectures in ambient air conditions of high humidity. This would result in considerable cost savings ...
The emergence of graphene and other related 2-dimensional materials like hexagonal
boron nitride (hBN) and molybdenum disulfide etc., have boosted the polymer
nanocomposites (PNCs) particularly with their mechanical & ...
Elastomeric sponge and auxetic materials have unique characteristics which
distinguish them from other solid materials like metals and ceramics. Such
engineering materials with unique performance are a continuous requisite ...
This chapter is an effort of comparing numerical methods for the multicomponent membrane
gas separation. As an example for membrane gas separation, a detailed model of co-current
flow process is considered. After the ...
