The lack of soil data, which are relevant, reliable, affordable, immediately available, and sufficiently detailed, is still a significant challenge in precision agriculture. A promising technology for the spatial assessment of the distribution of chemical elements withi...

Network coding can be very useful in achieving a balance between energy efficiency and end-to-end packet error in sensor networks, particularly if only a subset of the nodes act as encoding nodes. In this article, a mathematical model and a heuristic algorithm are propo...

Abstract Background The smoked fishery sector of Ghana plays an important role in terms of food security, employment creation, income generation and foreign exchange earnings aiding sustainable development of the Ghanaian economy. Fish smoking is the leading technique o...

Chiral discrimination has become one of the most important fields in analytical and medicinal chemistry, and forensic toxicology. The enantiomers may have different binding to proteins that may lead to many pharmacological and toxicological differences between them, inc...

Xanthone derivatives have been described as compounds with a privileged scaffold exhibiting diverse biological/pharmacological activities, what directed the interest to pursue the development of these derivatives into drug candidates. Nevertheless, to achieve this purpo...

Current regulation for marine toxins requires a monitoring method based on mass spectrometric analysis. This method is pre-targeted, hence after searching for pre-assigned masses, it identifies those compounds that were pre-defined with available calibrants. Therefore, ...

Recently, molecular imprinted polymers (MIPs) were extensively used for separation and identification of specific molecules, replacing expensive and unstable biological receptors. Nonetheless, their application in electrochemical sensors has not been sufficiently explor...

AbstractThe oleoresin of Copaifera reticulata Ducke, Fabaceae, is a traditional Brazilian remedy used for a wide range of applications. Commonly named copaiba, the oleoresin has been found to exhibit strong antimicrobial effects in our previous study, which could be att...

A series of ultrathin, homogenous gold nanoparticle (AuNP) substrates for surface-assisted laser desorption/ionization mass spectrometry (SALDI-MS) were prepared using a simple air/water interface ...

Established laser-based ionization experiments require the surface of a sample to be as flat as possible to guarantee optimal laser focus. A laser ablation electrospray ionization ( LAESI) source was custom-built to accommodate the topography of non-flat sample surfaces...
