background and objective: sorbitol is a non-toxic and slightly hygroscopic compound with different applications. zymomonas mobiles produces sorbitol from sucrose or mixtures of glucose and fructose (formation is coupled with the dehydrogenation of glucose to glucono-δ- lactone). recombinant zymomonas mobilis may produce sorbitol and gluconic acid from glucose and fructose using different divale...

in this study, physical vapor deposition (pvd) ti-cr-n coatings were deposited at two different temperatures100 and 400ºc on hardened and tempered tool steel substrates. the influence of the applied deposition temperature on the physical and mechanical properties of coatings such as roughness, thickness, phase composition, hardness and young’s modulus were evaluated. phase compositions were stu...

Due to their non-toxic nature, biodegradability and production from renewable resources, research has shown an increasing interest in the use of biosurfactants in a wide variety of applications. This paper reviews the characterization of rhamnolipid and sophorolipid biosurfactants based on their hydrophilicity/hydrophobicity and their ability to form microemulsions with a range of oils without ...

Applications of nanowires into future generation nanodevices require a complete understanding of the mechanical properties of the nanowires. A great research effort has been made in the past two decades to understand the deformation physics and mechanical behaviors of nanowires, and to interpret the discrepancies between experimental measurements and theoretical predictions. This review focused...

These are listed here into broad categories: Some of these methods are briefly described here. SCATTERING METHODS This author's research interests...

ferdowsi's shahname is a literary work with many and varied personalities which can be converted to dramatic texts, but it needs to analyze on basis theories of dramatic characterization. characterization of the protagonist of the play, as a key element of the show has a special component such as action and motivation to handle dramatic action, a physical and mental characteristic that dis...
