Reprint of "Three-dimensional elemental mapping of phosphorus by quantitative electron spectroscopic tomography (QuEST)" [J. Struct. Biol. 160 (2007) 35-48].

Journal of structural biology

Aronova MA, Kim YC, Harmon R, Sousa AA, Zhang G, Leapman RD.
PMID: 18342742
J Struct Biol. 2008 Mar;161(3):322-35. doi: 10.1016/S1047-8477(08)00062-2.

We describe the development of quantitative electron spectroscopic tomography (QuEST), which provides 3-D distributions of elements on a nanometer scale. Specifically, it is shown that QuEST can be applied to map the distribution of phosphorus in unstained sections of...

Reprint of "On the feasibility of visualizing ultrasmall gold labels in biological specimens by STEM tomography" [J. Struct. Biol. 159 (2007) 507-522].

Labeling with heavy atom clusters attached to antibody fragments is an attractive technique for determining the 3D distribution of specific proteins in cells using electron tomography. However, the small size of the labels makes them very difficult to detect...

A method for determination of COD in a domestic wastewater treatment plant by using near-infrared reflectance spectrometry of seston.

Anal Chim Acta. 2007 Apr 11;588(2):231-6. doi: 10.1016/j.aca.2007.02.022. Epub 2007 Feb 20.

This paper proposes a method for determination of chemical oxygen demand (COD) in domestic wastewater. The proposed method is based on near-infrared reflectance (NIRR) measurements of seston collected from wastewater samples by filtration. The analysis does not require any...

Prediction of the mechanical properties of hydroxyapatite/polymethyl methacrylate/carbon nanotubes nanocomposite.

Journal of nanoscience and nanotechnology

Shokuhfar T, Makradi A, Titus E, Cabral G, Ahzi S, Sousa AC, Belouettar S, Gracio J.
