Silica sulfuric acid is found to catalyze efficiently the condensation of o-phenylenediamines with various linear and cyclic ketones to afford the corresponding 1,5-benzodiazepines in quantitative yields under solvent-free conditions at room temperature

a simple, fast and one-pot synthesis procedure based on the bioreduction ability of an algal extract solution has been developed to produce silver nanoparticles (agnps). we focus especially on the influencing factors of agnps formation. the effects of various factors like ph, temperature, the concentration of metal ions and alga, the volume ratio of silver nitrate solution to alga extract, reac...

A fast and greensolution-phase peptide synthesis (GSolPPS) via continuous protocol, addressed with propylphosphonic anhydride T3P® as coupling reagent N -benzyloxycarbonyl-protecting group easily removed by hydrogenation is herein reported.

[reaction: see text] Chemical glycopeptide synthesis requires access to gram quantities of glycosylated amino acid building blocks. Hence, the efficiency of synthesis of such building blocks is of great importance. Here, we report a fast and highly efficient synthetic route to Fmoc-protected asparaginyl glycosides from unprotected sugars in three steps with high yields. The glycosylated amino a...

A fast approach for synthesizing gold nanoparticles over electrochemical paper-based devices is reported. The device was fabricated by paper laser pyrolysis carbonization followed in situ synthesis of AuNPs.

The paper presents a versatile technique of the construction of multivariate models of interresonator couplings. These models are based on results of electromagnetic simulations and can be used for fast synthesis of coupled resonator filters with complex geometry (like combline or dielectric resonators filters). To demonstrate the usefulness of the models, an example of synthesis of filter in t...

In this presented paper, to accomplish semiconductor device synthesis for TCAD application, the Parallel Genetic Algorithm is applied as the core searching algorithm for “acceptability region” of device designables, which satisfy the designed device performance. The results of some experiments on FIBMOS are shown, which indicate the Parallel Genetic Algorithm is an efficient and fast searching ...

A method of fast linear transform algorithm synthesis for an arbitrary tensor, matrix, or vector is proposed. The method is based on factorization of a tensor and using the factors for building computational structures performing fast tensor vector multiplication on a computer or dedicated hardware platform.

Electron-density averaging, fast Fourier synthesis and fast Fourier analysis programs have been adapted for parallel-computing systems. These have been linked to perform iterative phase improvement and extension utilizing non-crystallographic symmetry and solvent flattening. Various strategies for parallel algorithms have been tested on a variety of computers as a function of the number of comp...

Skeletal muscle protein synthesis is elevated in neonates in part due to an enhanced response to the rise in insulin and amino acids after eating. In vitro studies suggest that glucose plays a role in protein synthesis regulation. To determine whether glucose, independently of insulin and amino acids, is involved in the postprandial rise in skeletal muscle protein synthesis, pancreatic-substrat...
