Nanocomposite-graphene based platform for heavy metal detection
… was used as a sensing platform for trace metal analysis in 0.1 M acetate buffer (pH 4.6) at 120 s deposition time, using square-wave anodic stripping voltammetry (SWASV). Detection limits were calculated using 3σblank/slope. For practical applications recovery studies was done by spiking …

Self-Assembled Monolayers of N-Heterocyclic Carbenes on Gold and Silver: Applications in Biosensing
Modification of metallic surfaces using thiol-based self-assembled monolayers (SAMs) has been explored in the literature in the past three decades; silver surfaces less explored than gold. This technology has promise in many surface-based applications, specifically in micro electronics, sensors …

The Determination of Trace Metals by High Performance Liquid Chromatography with Photometric Detection
The importance of trace metals and their species is reviewed and it is recognised that improved methods of determination are required. High performance liquid chromatography has grown in importance as a technique, especially since the synthesis of better column packings. The adaptability of reverse …

The synthesis and investigation of alizan-based functional chromogenic probes for heavy mental sensing in aqueous medium
Heavy metal contamination of drinking water is a global concern. Conventional analytical techniques that are commonly used for metal ion detection in water, such as atomic absorption spectrometry and mass spectrometry, are not suitable for mass monitoring purposes. Suitable chromogenic probes could …

Comparison of Archeological Survey Techniques at Camp Lawton, a Civil War Prison Stockade
In 2009, Dr. Sue Moore of Georgia Southern University was contacted by State Archeologist Dr. Dave Crass of the Georgia Department of Natural Resources Historic Preservation Division. He proposed an exploratory survey of the site of a Civil War Confederate prisoner of war camp known as Camp Lawton …

XRF and the Corrosion Environment at Camp Lawton: A Comprehensive Study of the Archeological Microenvironment of a Civil War Prison Camp
… chemical analysis between a given ferrous metallic artifact's corrosion environment (the surrounding soil matrix) and the subsequent corrosion products formed on the artifact. The hypothesis is that the data will demonstrate a chemical correlation between the two. Iron and chlorine are the …
