Bonding and chemical efficiency of these compounds where measured at NTP laboratory conditions for manufacturing of various targeted drugs and polymers. Actually, polyatomic molecules containing a specific functional group produce electronic absorption spectra which show some interesting similarities. Extensive investigations have been carried out on molecules containing some groups like carbonyl group and azole group and the similarities found have been attributed to the effects of functional groups. As expected, Imidazole and Furfural should have loan pair of electrons on Nitrogen atom and consequently their spectra should show the presence of an σ-> transition as a lowest energy transition. This result is in line with our predicted spectra of these molecules. These compounds have importance in organic chemistry. The study of these properties requires a correct understanding of the physical, chemical and other allied problems, their causes and solutions. So, any contribution of investigations on this line will be of considerable importance.

Whereas 3He is a Fermi particles and it follows Fermi Dirac Statistics and also Pauli Exclusion Principal. Both these particles are well separated out and at low temperature they are in liquid form. Liquid 4He is a normal Bose liquid whereas liquid 3He is a Fermi liquid. These two liquids are also called Quantum liquids. At T = 2.17 K liquid 4He goes into famous phase transition called λ-transition. Above λ Temperature i.e. Tλ = 2.17 K 4He is a normal liquid also called He-I and below λ Temperature it is a superfluid also called He-II. In liquid 3He, phase transition occurs at very low temperature, about 2.7 mK. Between 3 mK to 100 mK liquid 3He is a normal liquid and below 3mK they are in a superfluid phase and these phases are also mesophase called 3He-A phase and 3He-B phase. These phases are observed through NMR experiments. These phases are also spin polarised phase. It is generally belief that superfluidity is a flow of liquid without viscosity. In case of superfluid He-II the value of viscosity is almost negligible. Where in two phase of superfluid 3He, He – A phase is almost negligible viscosity whereas He-B phase has finite value of viscosity which is in Tensor form having first order (shear) and second order viscosity.

Cenosphere is an inexpensive waste generated in bulk from thermal power station. It can be use as a reinforcing material in various composite systems. In this study, particulate composite of TPU-PP (matrix phase) and cenosphere (reinforcing phase) are prepared and extensively studied with respect to their modified and unmodified interface. Non-surface treated cenosphere has been found to get agglomerate during their blending with polymer matrix which subsequently reduces its overall performance. So, its surface was modified by 3-aminopropyl triethoxy silane coupling agent and on the other hand matrix was modified by glycidyl methacrylate (PP-g-GMA). Surface modified cenosphere and synthesized compatibilizer were functionally characterized by FTIR spectroscopy. Composites of TPU-PP/cenosphere were prepared having cenosphere concentration between 5-20% by weight. Morphological studies of all the prepared composite variants were done by scanning electron microscope.

The probability for any given reaction to occur is in proportion to its cross section. Thus to find the cross section for a given reaction is a proxy for stating the probability that a given scattering process will occur. The total (σtot.) and differential (dσ) cross sections are among the most important measurable quantities and it can reveal a great amount of information about the internal structure of target particle. Differential cross section (dσ) in inelastic scattering contain resonance peaks that indicate the creation of metastable state and contain information about their energy and lifetime. The given study provides the calculations of total and differential cross-section of scattering of electron(intermediate energy) from target like metastable atom e.g. He and the study of electron density distribution of it.

Formation of minerals wollastonite and diopside has occurred due to thermal metamorphism of limes... more Formation of minerals wollastonite and diopside has occurred due to thermal metamorphism of limestone and dolomitic limestone containing siliceous impurity. The effect was induced in the rock as a result of development of large plug shape intrusion of troctolite (a gabbro containing titan augite + olivine + plagioclase) within the country rock limestone due to thermal metamorphism. The intrusion of magma must have been occurred under plutonic condition at a depth of more than ~ 7 km depth because the rock troctolite shows granitic texture (holocrystalline and hypidiomorphic texture) where rock is entirely made up of mineral crystals which are partly developed or subhedral. The rock is melanocratic in colour due to complete absence of quartz and presence of plagioclase and titan augite. The rock is basic in nature due to presence of plagioclase and titan augite and complete absence of orthoclase. The rock belongs to soda-lime series due to presence of plagioclase, where it is labradorite or bytownite type. The rock can be considered as of femic type due to presence of titan augite and olivine. The limestone is affected by temperature or heat effect only, which is considered under thermal metamorphism. Here, pressure may be generated only due to thermal expansion of the rock and crowding aside of the rock due to penetration of the magma, which is generally negligible. Further, water content in the magma must be less or absent, as a result of which limited metamorphic aureole is formed with no development of water containing mica or amphibole group of minerals. Furthermore, limestone must be dolomitic at places with siliceous impurity and only limestone with siliceous impurity must be present, which has given rise to CaCO3 + SiO2 = CaSiO3 + CO2. The CO2 must have escaped from the resulting wollastonite or might have been trapped in cavities which are found in wollastonite. Dolomitic limestone containing siliceous impurity has provided diopside with chemical reaction: CaMg(CO3)2 + 2SiO2 = CaOMgOSi2O4 + CO2. Here also cavities are present which suggest escape or trapping of CO2 in the rock. At places wollastonite-pyroxene rock occurs together indicating presence of both limestone and dolomitic limestone with silica as impurity.

Different chemical routes are used to prepare Strontium hexaferrite powders like ceramic route, co-precipitation method, sol-gel process, auto-combustion route, hydrothermal, micro-emulsion etc. Convention ceramic route requires high temperature calcinations (1400 ºC). Here Strontium hexaferrite SrFe12O19 particles containing polyoxyethelene (20) sorbitan monoolate (Tween-80) were synthesized by a chemical co-precipitation technique with a precipitator NH3.H2O. The prepared Sr-M hexaferrite precipitates were heat treated at various temperatures 650 ºC, 750 ºC, 850 ºC, 950 ºC and 1100 ºC for 4 hrs in a muffle furnace. The obtained Sr-M powders were characterized by using various instrumental techniques like FTIR, TGA, XRD, SEM and VSM. Their physical as well as magnetic properties were compared. It was observed from XRD results that heat treatment conditions play significant role in the formation of pure SrFe12O19 hexaferrite phase and also in the grain size. The estimated particle size is of the order of nanometer when suitable calcinations temperature is applied. SEM micrographs show an increase in crystallite size of the resultant SrFe12O19 hexaferrite particles sintered at higher temperature (1100 ºC).

The stability constants of the resulting 1:1 complexes were determined from computer fitting of the conductance versus mole ratio data. The values of stability constants of complexes, which were obtained from conductometric data, show that the stability of complexes is affected by the nature and composition of the binary mixed solvents. The corresponding thermodynamic parameters (∆H0, ∆S0 and ∆G0) were obtained from the temperature dependence of the stability constants using van’t Hoff plots. The results show that the values and also the sign of these parameters are influenced by the nature and composition of the mixed solvents.

The probability for any given reaction to occur is in proportion to its cross section. Thus to find the cross section for a given reaction is a proxy for stating the probability that a given scattering process will occur. The total (σtot.) and differential (dσ) cross sections are among the most important measurable quantities and it can reveal a great amount of information about the internal structure of target particle. Differential cross section (dσ) in inelastic scattering contain resonance peaks that indicate the creation of metastable state and contain information about their energy and lifetime. The given study provides the calculations of total and differential cross-section of scattering of electron(intermediate energy) from target like metastable atom e.g. He and the study of electron density distribution of it.

The effect was induced in the rock as a result of development of large plug shape intrusion of troctolite (a gabbro containing titan augite + olivine + plagioclase) within the country rock limestone due to thermal metamorphism. The intrusion of magma must have been occurred under plutonic condition at a depth of more than ~ 7 km depth because the rock troctolite shows granitic texture (holocrystalline and hypidiomorphic texture) where rock is entirely made up of mineral crystals which are partly developed or subhedral. The rock is melanocratic in colour due to complete absence of quartz and presence of plagioclase and titan augite. The rock is basic in nature due to presence of plagioclase and titan augite and complete absence of orthoclase. The rock belongs to soda-lime series due to presence of plagioclase, where it is labradorite or bytownite type. The rock can be considered as of femic type due to presence of titan augite and olivine. The limestone is affected by temperature or heat effect only, which is considered under thermal metamorphism. Here, pressure may be generated only due to thermal expansion of the rock and crowding aside of the rock due to penetration of the magma, which is generally negligible. Further, water content in the magma must be less or absent, as a result of which limited metamorphic aureole is formed with no development of water containing mica or amphibole group of minerals. Furthermore, limestone must be dolomitic at places with siliceous impurity and only limestone with siliceous impurity must be present, which has given rise to CaCO3 + SiO2 = CaSiO3 + CO2. The CO2 must have escaped from the resulting wollastonite or might have been trapped in cavities which are found in wollastonite. Dolomitic limestone containing siliceous impurity has provided diopside with chemical reaction: CaMg(CO3)2 + 2SiO2 = CaOMgOSi2O4 + CO2. Here also cavities are present which suggest escape or trapping of CO2 in the rock. At places wollastonite-pyroxene rock occurs together indicating presence of both limestone and dolomitic limestone with silica as impurity.

Different chemical routes are used to prepare Strontium hexaferrite powders like ceramic route, co-precipitation method, sol-gel process, auto-combustion route, hydrothermal, micro-emulsion etc. Convention ceramic route requires high temperature calcinations (1400 ºC). Here Strontium hexaferrite SrFe12O19 particles containing polyoxyethelene (20) sorbitan monoolate (Tween-80) were synthesized by a chemical co-precipitation technique with a precipitator NH3.H2O. The prepared Sr-M hexaferrite precipitates were heat treated at various temperatures 650 ºC, 750 ºC, 850 ºC, 950 ºC and 1100 ºC for 4 hrs in a muffle furnace. The obtained Sr-M powders were characterized by using various instrumental techniques like FTIR, TGA, XRD, SEM and VSM. Their physical as well as magnetic properties were compared. It was observed from XRD results that heat treatment conditions play significant role in the formation of pure SrFe12O19 hexaferrite phase and also in the grain size. The estimated particle size is of the order of nanometer when suitable calcinations temperature is applied. SEM micrographs show an increase in crystallite size of the resultant SrFe12O19 hexaferrite particles sintered at higher temperature (1100 ºC).

The stability constants of the resulting 1:1 complexes were determined from computer fitting of the conductance versus mole ratio data. The values of stability constants of complexes, which were obtained from conductometric data, show that the stability of complexes is affected by the nature and composition of the binary mixed solvents. The corresponding thermodynamic parameters (∆H0, ∆S0 and ∆G0) were obtained from the temperature dependence of the stability constants using van’t Hoff plots. The results show that the values and also the sign of these parameters are influenced by the nature and composition of the mixed solvents.

Present work comprises the chemical modification of starch by grafting vinyl monomers i.e. Methyl methacrylate and acrylamide in a homogeneous aqueous phase using ceric ammonium nitrate (CAN) as the initiator. All these three variants of starch was blended with low-density polyethylene (LDPE) in various composition. Low density polyethylene was grafted with maleic anhydride and subsequently used as a compatibilizer to promote the interfacial interaction between the ingredients. The characterization of the grafted products was confirmed by Fourier Transform Infrared spectroscopy (FT-IR) as well as Percentage grafting G (%), percentage efficiency E (%) and yield of graft copolymerization, Y (%) was determined. The prepared blends were subjected to Scanning Electron Microscopy (SEM), thermal gravimetric analysis (TGA) and biodegradation study.
