Integrated micro X-ray fluorescence and chemometric analysis for printed circuit boards recycling

A novel approach, based on micro X-ray fluorescence (μXRF), was developed to define
an efficient and fast automatic recognition procedure finalized to detect and
topologically assess the presence of the different elements in waste electrical and
electronic equipment (WEEE). More specifically, selected end-of-life (EOL) iPhone
printed circuit boards (PCB) were investigated, whose technological improvement
during time, can dramatically influence the recycling strategies (i.e. presence of

Characterization of microplastic litter from oceans by an innovative approach based on hyperspectral imaging

An innovative approach, based on HyperSpectral Imaging (HSI), was developed in order to set up an efficient method to analyze marine microplastic litter. HSI was applied to samples collected by surface-trawling plankton nets from several parts of the world (i.e. Arctic, Mediterranean, South Atlantic and North Pacific). Reliable information on abundance, size, shape and polymer type for the whole ensemble of plastic particles in each sample was retrieved from single hyperspectral images.

Analytical procedures for secondary metabolites determination: recent trends and future perspectives

Background: Many studies have shown the benefits deriving from plants secondary metabolites to human health also for the prevention of several diseases associated to oxidative stress including cancer, cardiovascular diseases and diabetes mellitus. Nowadays there is a high attention on plant secondary metabolites and analytical techniques related to their identification and characterization. Conclusion: This review aims to report analytical procedures, instrumental configurations, and extraction approaches devoted to secondary metabolites analyses.
