Electrical, structural and morphological properties of Ni silicide films formed in Ni(Pt 4at.% )/Si(100) and Ni0.6Si0.4(Pt4at.% )/Si(100) structures at various annealing temperatures ranging from 200 to 1000 oC were studied. The Ni(Pt) and Ni0.6Si0.4(Pt) films with thickness of 15 and 25 nm were deposited by RF magnetron co-sputtering method, respectively.  The annealing process of the structur...

We explore the dynamics of blue emission from dodecylamine and ammonia functionalized silicon nanocrystals (Si NCs) with average diameters of ∼3 and ∼6 nm using time-resolved photoluminescence (TRPL) spectroscopy. The Si NCs exhibit nanosecond PL decay dynamics that is independent of NC size and uniform across the emission spectrum. The TRPL measurements reveal complete quenching of core state ...

We report on the initial stage of growing of silicon nanostructures on Pb-induced √ 3 × √ 3 and √ 3 × √ 7 reconstructed Si(111) surfaces. The deposition of 0.75 monolayer of Si at a temperature of around 200 K results in Si nanoribbons a few-nanometers in length running in three equivalent high symmetry directions of Si(111) surface, as revealed by low temperature scanning tunneling microscopy ...

BACKGROUND In hypertrophic cardiomyopathy (HCM), the arrhythmic potential associated with a variety of left ventricular myocardial signal intensities evident on contrast-enhanced cardiovascular magnetic resonance with late gadolinium enhancement (LGE) is unresolved. METHODS AND RESULTS In 145 HCM patients (43±15 years old), visually identified areas of LGE in left ventricle were analyzed quan...

The most commonly used method for the production of thin films is based on deposition of atoms or molecules onto a solid surface. One of the suitable method is to produce high quality metallic, semiconductor and organic thin film is Ionized cluster beam deposition (ICBD), which are used in electronic, robotic, optical, optoelectronic devices. Many important factors such as cluster size, cluster...

A long term study was done to assess the impact of on farm reservoirs (OFR) on oil seedand cereal based cropping systems with vegetables (okra, tomato and carrot) in semi-aridalfisol of southern Telangana region. Two supplemental irrigation (SI) depths (30 and 50 mm)from OFR with raingun system were studied for assessing the water productivity andprofitability of the technology in these croppin...

BACKGROUND Physical activity (PA), weight-bearing exercises (WBE) and muscle strength contribute to skeletal development, while sedentary behaviour (SB) adversely affects bone health. Previous studies examined the isolated effect of PA, SB or muscle strength on bone health, which was usually assessed by x-ray methods, in children. Little is known about the combined effects of these factors on b...
