le chatelier's principle is used as a very simple way to predict the effect of a change in conditions on a chemical equilibrium. . however, several studies have reported the violation of this principle, still there is no reported simple mathematical equation to express the exact condition of violation in the gas phase reactions. in this article, we derived a simple equation for the violati...

Abstract Molecular imprinting-based solid-phase extraction has been in the spotlight to improve recognition selectivity and detection sensitivity of andrographolides. The synthesis molecularly imprinted polymers on micro centrifuge tube filters for determination andrographolides were investigated. Molecularly synthesized using photo-polymerization method preconcentration (AD) template molecule ...

In a distributed system multiple nodes may initiate snapshot collection concurrently. In this paper we present a global snapshot collection algorithm that combines the information collected by each initiator. This generates a maximal, consistent global snapshot that is more recent than the snapshot collected by any initiator. Global snapshots are used to establish checkpoints for recovery from ...

Syntheses of organometallic initiators were conducted under a nitrogen atmosphere using standard Schlenk techniques. All reagents were of commercial grade and obtained from Sigma-Aldrich Co.. Solvents and the propionic acid used for the preparation of initiators were carefully dried and distilled under nitrogen atmosphere prior to use. TEMPO was sublimated and stored under nitrogen atmosphere. ...

By using a two stage model of carcinogenesis, we generated Monte Carlo studies to assess the efficiency and robustness of the 3-poly test for animal carcinogenicity experiments. The Monte Carlo results indicate that the 3-poly test is quite powerful for detecting the carcinogenic effects of complete carcinogens, moderate promoters, and initiators with moderate or large effect, but, in some case...

• Nanoarchitectonics approach to synthesize functionalized CNTs was proposed. were using new multifunctional initiators. Nanocomposites with MPIs fabricated. New nanocomposites possessed improved physic-mechanical properties. In this work, the nanoarchitectonics a functional material certain configurations and hierarchical motifs of initiators surface-initiated radical polymerization (MPIs) on ...

The iSCSI protocol provides access to SCSI devices over a TCP transport. Using the iSCSI protocol enables one to build a Storage Area Network using standard Ethernet infrastructure and standard networking management tools. This paper outlines how we implemented a family of iSCSI initiators on a common core. The initially supported initiators were on the Windows NT and the Linux Operating System...

We describe here a well-behaved initiator for ring-opening alkyne metathesis polymerization (ROAMP) of dibenzocyclooctynes. The reaction produces living polymers with low polydispersities and predictable molecular weights. We activate the well-known alkyne metathesis precatalyst, [(N(tBu)Ar)3MoCCH2CH3], with phenolic ligands that have σ-electron donating substituents. We show that the chelatin...

Iso-selective initiators for the ring-opening polymerization (ROP) of rac-lactide are rare outside of Group 13. We describe the first examples of highly iso-selective lutetium initiators. The phosphasalen lutetium ethoxide complex shows excellent iso-selectivity, with a P(i) value of 0.81-0.84 at 298 K, excellent rates, and high degrees of polymerization control. Conversely, the corresponding L...
