On the synthesis and optical absorption studies of nano-size magnesium oxide powder
Abstract Magnesium oxide (MgO) nano-size powder is synthesized using magnesium nitrate hexahydrate and oxalic acid as precursors with ethanol as a solvent. The process involves gel formation, drying…
On the sol–gel synthesis and thermal, structural, and magnetic studies of transition metal (Ni, Co, Mn) containing ZnO powders
Transition metal containing ZnO powders (Zn1−xMxO, 0≤x≤0.30; M = Ni, Mn, Co) have been synthesized by a sol–gel process using zinc acetate dihydrate, respective acetate and oxalic acid as precursors…
Optical, electrical and magnetic properties of Co3O4 nanocrystallites obtained by thermal decomposition of sol–gel derived oxalates
Abstract Nanocrystallites of tricobalt tetraoxide (Co 3 O 4 ) have been synthesized by sol–gel process using cobalt acetate tetrahydrate, oxalic acid as precursors and ethanol as a solvent. The…
A comparative study of the magnetic properties of bulk and nanocrystalline Co3O4
A comparative study of the magnetic and electron paramagnetic resonance (EPR) parameters of bulk and Co3O4 nanoparticles (NP), synthesized by a sol–gel process, is presented. Both samples possess the…
Current transport in Pd2Si/n-Si(100) Schottky barrier diodes at low temperatures
The forward current-voltage (I–V) characteristics of Pd2Si/n-Si(100) Schottky barrier diodes are shown to follow the Thermionic Emission-Diffusion (TED) mechanism in the temperature range of 52-295…

Variation in ZnO optical bandgap occurring with Ga doping and insertion of additional zinc species has been explained by invoking two competing phenomena, namely bandgap widening and renormalization, usually observed in semiconductors with increasing carrier concentration.
Effect of thermal annealing on surface morphology and physical properties of poly(3-octylthiophene) films
Abstract An unusual morphology observed in poly(3-octylthiophene) (P3OT) films, solution grown at room temperature, which is previously shown by highly regioregular-poly(3-alkylthiophenes)…
The many facets of adenine: coordination, crystal patterns, and catalysis.
The emerging use ofAdenine nucleobase for the design of metal-nucleobase frameworks and the use of supramolecular adenine coordination complexes for transferring molecular properties onto surfaces is described.
On the existence of a distribution of barrier heights in Pd2Si/Si Schottky diodes
The current–voltage characteristics of Pd2Si based Schottky diodes on both n‐ and p‐type silicon measured over a wide temperature range (52–295 K) have been interpreted on the basis of thermionic…
Current-voltage characteristics and barrier parameters of Pd2Si/p-Si(111) Schottky diodes in a wide temperature range
Current-voltage characteristics of Pd2Si/p-Si(111) Schottky barrier diodes studied over a wide temperature range (60-201 K) are shown to follow a thermionic emission-diffusion mechanism under both…
