Alkylene dithiophosphate derivatives of macrocyclic complexes of Nickel (II), having N2S2 potential donors, of the
catheters, stents and pacemakers as well as biosensors for clinical diagnostics and, more recently, lab-on-a-chip technology. Medical applications – which involve surfaces made of titanium, stainless steel, ceramics or polymers – have spawned considerable research into the molecular and cellular interactions 25 that o…
Coconut seed (cocos nucifera L.) is a tropical plant that is grown in temperature between 200C and 250C. As part of steps towards the development of processing and handling equipments for the seeds, some engineering properties such as size, sphericity, roundness, volume, surface area, density, coefficient of friction…
Twin-roll casting applies the direct conversion of liquid metal into thin sheet. Besides the twin-roll caster, additional process equipment for hot or cold rolling is not needed. Low capital investment and metal conversation costs continue to make it a process of choice for metallic sheet today. Not only the twin-roll…
Chevkinite-(Ce) occurs in the rhyolitic tuff of the Mineoka group from Boso Penin- sula, Chiba Prefecture, Japan. It forms as black tiny crystals less than 100 μm across in association with zircon, quartz, K-feldspar and analcime. Optically, chevkinite-(Ce) is pleochroic in brown and blackish brown. The electron micro…
The use of hydrogen as the atmosphere for sintering titanium is a novel and attractive method that has recently been developed for sintering Ti-6Al-4V alloy to produce a fully dense powder metallurgy (PM) Ti-6Al-4V alloy with fine or ultrafine microstructure. This method includes three steps: hydrogen sintering, eutec…

The concentration of the Naturally Occurring Radioactive material (Norm) of soil and plant samples collected from nearby villag es to udaipur and their host communities was measured by determining the gross alpha activity concentration. Determination of the gross alpha radioactivity of soil, field soil and plant sampl…
Single crystals of L-Histidinium Trifluoroacetate were grown from aqueous solution by slow evaporation technique. Single crystal X-ray diffraction analysis reveals that the crystal belongs to triclinic crystal system. The optical transmission studies show that the crystal is transparent in the entire visible region wi…
Results on synthesis, structural investigations and the morphology of complex perovskites of general formula PrCo 1–x Cr x O 3 (with x = 0, 0.33, 0.5, 0.67 and 1) are presented. The synthesis of the perovskites within this series was performed by solution combustion method using two different fuels: urea and glycine.…
Seagrasses meadows are highly productive ecologically and economically valuable ecosystems. Epiphytic diatoms were collected from the leaves of seagrass species in Enhalus acoroides in Thondi coastal region. The taxonomic composition was identical regardless of the seagrass species. This is the first record of this ep…
Polycrystalline zinc sulfide (ZnS) films were prepared on glass substrates using a chemical bath deposition (CBD) technique in an aqueous/ethanolic solution. The films were characterized by X-ray diffraction (XRD) and electrical conductivity measurement. The XRD studies revealed that the deposited films have a polycry…
Most anticancer drugs are greatly limited by the se rious side effects that they cause. Tamoxifen is to xic to cancer cells and used against breast cancer. However, it m ay lead to irreversible cardio toxicity, which coul d even result in congestive heart failure. It decreases white blood cells count with increased ri…
We studied the microcrystalline and nanocrystalline silicon thin films by means of Raman spectroscopy technique. The applied external electric field causes the changes in the electric dipoles' orientations to compensate the external field, and migration the atom of impurities, such as hydrogen, and point defects. The…
Within Electric Power Utility of Serbia 1991, a thermal power plant 'Kostolac B', power 2 × 350 MW, started. Based on the examination of steam boiler pipe system, it is confirmed that it is in a 'bad' shape. Its most jeopardized parts are evaporating heating surfaces. Considering that there are areas within the evapor…
Catalyst pellets are one of the most important factors in catalytic reactor design. In this research a single catalyst pellet of hydrodesulfurization reaction have been investigated. The governing mass and energy balance equations have been solved numerically under steady state and dynamic conditions aiming to find th…
The technique of liquisolid compacts is a promising method towards enhancing the dissolution of poorly soluble drugs. In the present study, the potential of liquisolid systems to improve the dissolution properties of water-insoluble agents was investigated using diclofenac sodium as the model drug. Several formulation…
The critical relationship between quantitative stru cture-property relationships (QSPRs) and the qualit y of the experimental data is discussed by using multiple li near regression (MLR) analysis and describe the act ivities and influences of the vibrational frequency ( stretchin g & bending ) for groups C=C and =CH 2…
Cobalt substituted Nickel-zinc ferrites of different compositions Ni0.95-xZn0.05CoxFe2O4 and Zn0.95xNi0.05CoxFe2O4 (where x = 0.00, 0.01, 0.02,0.03, 0.04, 0.05 and 0.06).have been prepared by citrate precursor method involving concerned metals and mixing them in solution state. Parts of the sol-gel powder heated at el…
A new RP-HPLC method was developed for selective and simultaneous determination of of Desogestrel and Ethinyl Estradiol Tablets. The chromatographic separation was achieved on a Zorbax SB C-18, 4.6 x 250mm, and 5µ column. The gradient LC method employs solutions A and B as mobile phase. The solution A milliQ water and…
