Microhardness and Electron Paramagnetic Resonance (EPR) measurements are performed on 20 Li2 O-(80-x) B2O3-xMnO glasses (where x = 0,10 to 20 in steps of 2 mol%) have been investigated to find out the role played by Mn 2+ on the structure of these glass. These glass samples have been prepared using a conventional melt…
In order to prepare conducting polyaniline composite and nanocomposite soluble in various organic solvents before and after doping, and we based on these experimentally resultants finding, the present study relate to a new process for preparing conducting polyaniline with controlled molecular weight, high solubility i…
The purpose of this review is to provide an update on the current knowledge within this field of ocular drug delivery. Ocular drug delivery has been a major challenge for scientists due to its unique anatomy and physiology which contains various types of barriers such as different layers of cornea, sclera and retina i…
Surface plasmon polariton (SPP) is an electromagnetic excitation that propagates along the interface between a metal and a dielectric medium and is generated by resonant interaction between the surface charge oscillation and the electromagnetic field of light. This excitation decays exponentially with increasing dista…
Paleoclimate was reconstructed by the clay mineral assemblage of clay units in Mamu formation of Northern Anambra Basin. Collected samples were prepared using standard clay mineral methodology. Their identification was made on X-ray diffractographs, the results show that the clay mineral is predominantly kaolinitic wi…
The ledeburitic steel Vanadis 6 has been austenitized at the temperatures 1000 – 1075 o C, nitrogen gas quenched and 2x tempered at the temperatures 480 – 600 o C. Each tempering cycle was 2 h. Sub-zero treatment carried out via various regimes has been inserted in-between quenching and tempering, except one set of sp…
Epilithic and Epiphytic diatoms from stones and macrophytes are collected in Cauvery river at Bhavani region in Erode District, Tamil Nadu State and examined by using Light Microscopy (LM). Sixty diatoms belonging to twenty two genera species are identified. The fresh water species Synedra ulna (Nitzsch) Ehrenberg is…
In this work we report the phase structures of the EL-Hard padding weld layers and their effect on their abrasive wear resistance. The application of light and electron scanning microscopy examinations revealed subtle differences in the structures of the padding welds which affect their strength and usable properties.…
This paper documents test data on the effects of materials and processes on microvia structures. Thirteen sets of experiments were carried out to evaluate the effects of dielectric material, aspect ratio, via morphology, surface preparation, temperature and copper plating type and thickness on microvia reliability. Re…
The effect of strain rates on 0.19% C mild steel under tensile loading has been presented in this work. An electronic tensometer was used to conduct the test by varying the strain rates. Optical microscope and micro-hardness tester were used to characterize the microstructural orientations and hardness respectively ar…
Titanium dioxide nanoparticles (nTiO2) are usually perceived as non-toxic, and have been extensively used in many products and applications. Whilst short-term studies that revealed no/low toxicity of nTiO2 to cells and eco-relevant organisms, the long-term impact of nTiO2.on the environment and human health is still a…
In this study new mathematical models were proposed and developed by using a regression equation for the predicti on of impact energy absorption of h ybrid ferrocement slabs . Slabs were made up of self - compacting concrete (SCC) in order to minimize the external vibration work. Slabs of size 300 X 300 mm with varyin…
A socio-cognitive computational algorithm, viz., particle swarm optimization (PSO) has been adopted along with negative factor counting technique and inverse iteration method (IIM) for investigating the electronic properties of a model binary copolymer, of Type I class of quasi one-dimensional polymeric superlattices.…
alloyed with Ni and modified with Mo are investigated and described in the present study. The changes in the microstructure largely are determined by the presence of Ni in the composition of the alloy. The investigations were made for a case when the content of additional alloying element is fixed on 3%. Modification…
Existing stone crushing and size reduction process requires large quantity of electrical power. It creates environmental pollution with dust cloud, health hazards, noise etc, which have adverse effect on human organism and biological environment. It involves much manual labor in the polluted environment. Workers often…
Comprehensive monitoring and tracking of sensitive nuclear materials can be achieved with radio frequency identification (RFID) technology, resulting in significant improvement of the operating efficiency of nuclear and radiological facilities. A system, called ARG-US, has been developed by Argonne National Laboratory…
The solid complexes of La(III), Ce(III), Pr(III), Nd(III), Sm(III) and Gd(III) with asymmetrical tetradentate Schiff bases derived from 4-methyl-o-phenylenediamine, 3-Acetyl-6-methyl-pyran-2,4-dione and 2-hydroxy-1-naphthaldehyde have been synthesized and characterized by elemental analysis, conductometry, magnetic su…
In microbiologically influenced corrosion (MIC) stu dy, the electron acceptor of the cathode plays a de cisive influence on corrosion characteristics. Some bacter ia which can directly absorb electrons releasing fr om the anode reaction of the microbial dissolution of iron have been found in anaerobic biofilm studies,…
THz (Terahertz) radiation sources are an important research topic in THz science and technology. Novel THz radiation using double negative metamaterials (DNMs) and electron beam bunches is a promising candidate. In this review paper, we first introduce THz metamaterials, especially DNMs, including the design, fabricat…
Ramipril is an angiotensin-converting enzyme (ACE) inhibitor, used to treat high blood pressure and congestive heart failure. In the present study, urea, a well-known adductor for linear compounds was successfully employed for inclusion of Ramipril—a substituted cyclic organic compound through a modified technique usi…
