Black-bone silky fowl iron(II)-oligopeptide chelate was synthesized from iron(II) solution and the black-bone silky fowl oligopeptide, which was extracted from the muscle protein of black-bone silky fowl (Gallus gallus domesticus Brisson). Orthogonal array analysis was used to determine the optimal conditions for the iron(II)-oligopeptide chelate preparation. Ultraviolet-visible (UV-Vis) spectr...

A dithienyl unit in a N,C-chelate monoboryl compound has been found to completely stabilize a N,C-chelate boryl chromophore toward photoisomerization. N,C-chelate diboryl compounds that contain a dithienyl unit display a similar high stability toward photoisomerization. This greatly enhanced photostability is attributed to the π → π* transition and luminescence involving the dithienyl uni...

A new diphosphine ligand assembled on the cyclotriphosphazene platform forms linear chelate and dimetallic bridged complexes with Au(I) and a cis-chelate complex with Pt(II).

study of the nuclear magnetic resonance spectra of glyoxaldihydrazone in dimethylsulfoxide and deuterochlorofonn leads to the conclusion that this compound exists predominantly in non-chelate structure

Biological and nano fertilizers are alternative supplements to chemical security for the sustainability of agricultural production. This study is present investigate effect biological on quantitative qualitative yield cow pea during two crop years (2018-2019 2019-2020) in research farm South Agricultural Research Education Center Kerman province, Iran. experiment was carried out factorial desig...

in order to study the effect of iron chelate (fe-eddha) on some biochemical characteristic of safflower (carthamus tinctorius l.) under two irrigation regimes, a field experiment was set up a split-plot based on randomized block design with four replication in 2011 in a research field of the faculty of agriculture at shahed university. in this study the main plots consisted of two levels of irr...

Nano fertilizers are new products which contain readily available nutrients in the nano scale range and are preferred largely due to their efficiency. This research was conducted to assessment the effect of nano chelated of micro nutrient on agronomic traits of Cowpea via factorial experiment based on randomized complete block design with four replications during 2016 seasonal year. The treatme...

This experiment was designed to investigate the effects of different levels copper–methionine chelates and alfalfa powder on egg yolk cholesterol content, quality, performance in laying hens. In this experiment, a total 100 hens (Nick Chick strain, from 109 117 weeks age) were arranged into five experimental treatments, consisting 2 dietary copper chelate (2x2) factorial completely randomized d...

Excess di(tert-butyl)silylene (DTBS) bis(trifluoromethanesulfonate) formed bis-DTBS derivatives with the four aldopentoses (arabinose, lyxose, ribose and xylose). The structure of the bis-chelates was affected by the bulk of the DTBS groups and the requirement of flat silacycles in the case of five-membered chelate rings. These restrictions resulted in unusual cyclic bis-chelates for ribofurano...
