Synthesis and fast transfer of monolayer MoS on reusable fused silica.

Atomically thin, two-dimensional materials ranging from superconductors, metals, semiconductors to insulators are emerging as potential candidates for the next-generation digital electronics and optoelectronic applications. Their synthesis on a commonly used substrate and fast transfer to a plenty of desired substrates need to be addressed to meet the industrialization criteria for practical applications. In this study, fused silica, which is amorphous, transparent, and inexpensive, was examined as a substrate for MoS synthesis.

Role of power Doppler sonography in evaluation of therapeutic response of the knee in juvenile rheumatoid arthritis.

The objective is to study the role of power Doppler sonography (PDS) in assessment of therapeutic response in juvenile rheumatoid arthritis (JRA) of knee joint. Thirty patients (age range 3-11 years) of JRA with knee joint involvement were selected for this study. Clinical assessment and ultrasound was done on the same day and repeated at the end of second and sixth month of therapy.
