Regarding the green chemistry's goals, dicationic magnetic room temperature ionic liquid open up new avenue to introduce an amazing and efficient system for facilitating catalyst recovery in different organic reactions. Ability of this dicationic magnetic room temperature ionic liquid catalyst in the one-pot three-components condensation reaction of benzil, aromatic aldehyde, and ammonium aceta...

We investigate the characteristics of constant-amplitude input shapers for robust time-optimal maneuvers of exi-ble structures. Trends in the timing of the shaper impulses are shown as a function of the system damping constant and move distance. The insensitivity to modeling errors, time-optimality, amount of vibration caused during maneuvers, and high frequency excitation of these shapers are ...

An efficient protocol for the selective oxidation of primary alcohols to aldehydes withH5IO6/V2O5 in ionic liquid [bmpy][PF6] has been developed. High yields of the products, mildreaction conditions and simple experimental procedure make this protocol complementary tothe existing methods. The catalyst can be reused for several times without obvious loss of thecatalytic activity.

An efficient and green method for the synthesis of pyrano[3,2-c]chromene or pyrano[4,3-b]pyrone derivatives is described by using a three-component condensation process of malononitrile, aldehyde, and 4-hydroxycoumarine or 4-hydroxypyrone in [BMIm]BF4-LiCl as an ionic liquid.

The aim of this work was to determine the effects of two geographically different strains of Rhizophagus intraradices (M3 and GA5) on the total biomass and essential oil (EO) yield and composition of Calamintha nepeta, with or without phosphorus (P) fertilization, under greenhouse conditions. The plant biomass was not significantly affected by any of the treatments, showing higher values in con...

Most online feedback mechanisms publish unbiased statistics (usually averages) of past ratings. Such mechanisms fail in environments where the same seller sells products of many different qualities, such as marketplaces of used cars and collectibles. This paper presents a novel feedback management mechanism that succeeds in facilitating efficient transactions in such settings. One particularly ...

The attractive features and scientific challenges offered by the liquid wall systems render them strong candidates for investigation in the APEX project[1]. In particular, their high power density capabilities make the fusion reactors economically competitive. In this paper, as part of evolving a practical design based on this evolutionary idea, issues concerning thermalhydraulics of liquid sur...

In this study, bacterial strains were isolated from soils from 30 locations of Samcheok, Gangwon province. Of the isolated strains, seven showed potential plant growth promoting and antagonistic activities. Based on cultural and morphological characterization, and 16S rRNA gene sequencing, these strains were identified as Paenibacillus species. All seven strains produced ammonia, cellulase, hyd...
