Molybdenum disulfide (MoS2) few-layer films have gained considerable attention for their possible applications in electronics and optics also as a promising material energy conversion storage. Intercalating alkali metals, such lithium, offers the opportunity to engineer electronic properties of MoS2. However, influence lithium on growth MoS2 layers has not been fully explored. Here, we studied ...

abstract         sasanian dynasty, who governed as the last and the most glorious dynasty before islam in iran, has had an important role in enrichment of sasanian silver works and we owe the majority of silver works to this era. metalwork is one of the oldest arts iniranian civilization. the prominent metalwork crafts‚ left from different ages‚ acknowledge this fact. the art of this era has di...

Abstract Horizontal vibrating centrifuge and vertical scraper are the main equipment for dehydration of final coal in preparation plant. They widely used. There many misunderstandings actual selection centrifuges, which brings unnecessary problems to later use. In view how reasonably select two kinds improve use effect structural composition, working principle maintenance cost centrifuges compa...

In several mammals only one of the two types of retinal horizontal cell, the axonless A-type, appears to express neurofilaments. Neurofilament immunostaining of rodent retinas reveals a horizontal cell plexus that has previously been interpreted as belonging to A-type cells. Our intracellular Lucifer yellow injections strongly suggest that there are no A-type horizontal cells in rat and gerbil....

Laser Doppler Velocimetry (LDV) has been employed to determine pseudo-turbulence characteristics of the flow field around bubble train forming in non-Newtonian caboxymethylcellulose (CMC) aqueous solution at low gas flow rate condition. The Reynolds stress and turbulent intensity of the liquid were investigated by means of Reynolds time-averaged method. The experimental results show that ax...

the previous studies show that a high percentage of traffic accidents take place in two-lane rural highways and most of which happen at horizontal curves. meanwhile the horizontal alignment is often subject to hard topographic conditions where because of economic aspects designers are forced to design horizontal curves at grades. vertical angle of longitudinal slope reduces the normal force of ...

Microbial communities associated with marine sponges carry out nutrient transformations essential for benthic-pelagic coupling; however, knowledge about their composition and function is still sparse. We evaluated the richness and diversity of prokaryotic assemblages associated with three high-microbial-abundance (HMA) and three low-microbial-abundance (LMA) sympatric Mediterranean sponges to a...
