synthesis and characterization of two functionalized gold nanoparticles by using of two poly functional amino acids (l-arginine and l-aspartic acid) are reported. the gold nanoparticles were reduced by sodium citrate and functionalized with l-arginine at the ph of 7 and 11 and l-aspartic acid at the ph of 7. transmission electron microscopy, uv-vis spectroscopy, dynamic light scattering, zeta p...

Given a positive integer n, we let sfp(n) denote the squarefree part of n. We determine all positive integers n for which max{sfp(n), sfp(n+ 1), sfp(n+ 2)} ≤ 150 by relating the problem to finding integral points on elliptic curves. We also prove that there are infinitely many n for which max{sfp(n), sfp(n + 1), sfp(n + 2)} < n.

Cyclic voltammetry measurements on imidazolic ionic liquids with sulfonic acid groups and bisulfate counterions revealed that they work as efficient reservoirs of sulfuric are able to dose it demand uphold an catalysis.

A sentence-final particle (SFP, henceforth) is an optional component for a sentence in Cantonese. Traditionally an SFP contains at least one independent segment. The present study proposes that for sentences without a segmental SFP, sentencefinal intonation can act as a segmentless SFP. Systematical acoustic experiment was conducted based on this assumption. Two cross-cutting dichotomies were c...

Oil concentration (OC) in canola (B. napus L.) is determined during seed fillingperiod (SFP), and the variation in OC is greatly related to environmental conditionsduring that period. To determine factors affecting OC in canola, 12 fieldexperiments were conducted at Agricultural Research Station of Gonbad, Iran,during 2000-07. The experiments were carried out under different growingconditions. ...
