ICP-OES: An Advance Tool in Biological Research [PDF]

open access: yesOpen Journal of Environmental Biology, 2020
Spectroscopic analysis has been considered as a promising tool for the quantitative detection of elements in a biological sample. Inductively coupled plasma optical emission spectrometry (ICP-OES) is an advanced trace element analysis technique that uses the emission spectrum of an excited atom to detect and quantify the element present in the sample.

Unravelling the Atomic Structure of a Metal‐Covalent Organic Framework Assembled from Ruthenium Metalloligands

open access: yesAdvanced Materials, Volume 37, Issue 13, April 2, 2025.
Metal‐covalent organic frameworks (MCOFs) are novel porous materials that exhibit the advantages of covalent and metal‐organic frameworks. However, it is extremely difficult to resolve their atomic structure and better understand their structure‐properties relation. This work utilizes a synergistic combination of advanced microscopy, spectroscopic, and

Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

open access: yesAdvanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

Tannin resin-boron associations: Leaching and biological resistance [PDF]

open access: yes, 2012
The easy leaching of boron in wood preservation formulations has allowed to use this fungicide only for short term applications. The recently discovered adduct with flavonoids allows boron to resist longer periods of time within wood and consequently ...

Impact of the earthworm Lumbricus terrestris (L.) on As, Cu, Pb and Zn mobility and speciation in contaminated soils [PDF]

open access: yes, 2011
To assess the risks that contaminated soils pose to the environment properly a greater understanding of how soil biota influence the mobility of metal(loid)s in soils is required. Lumbricus terrestris L. were incubated in three soils contaminated with As,

Analyse römischer Ziegel mit ICP-OES/-MS

open access: yes, 2005
In dieser Arbeit wurde eine Messmethode mit ICP-OES und ICP-MS zur Bestimmung der Gehalte von bis zu 30 Elementen in römischen Ziegeln aus der Provinz Germania Superior entwickelt, die einen Vergleich mit zuvor gemessenen RFA Daten ermöglicht. Da Ziegel eine schwer aufzuschließende Matrix besitzen, wurden als erstes die optimalen Bedingungen für einen ...
