Microstructural evolution during mechanical alloying of Ag and Zn, and subsequent heat treatments were investigated. The mechanical alloying was carried out in a SPEX 8000D miller. The microstructural characterization was obtained by X-ray diffraction （XRD）, transmission electron microscopy （TEM） and scanning electron microscopy （SEM）. The thermal behavior was studied using differential scanning calorimetry （DSC）. Based on the results obtained, it can be concluded that at the early stages of milling was possible to detect the ε, β, β′, α solid solutions and remaining Zn. Later, the ε, β, β′ and Zn phases disappeared while the Zn concentration of the α solid solution was strongly increased. After 7.2 ks of milling, the mechanical alloying process reached a steady state. During this period, both the composition and crystallite size of the α solid solution remained practically unchanged. On the other hand, subsequent heat treatments of milled powders showed that the α solid solution could also be obtained by the combination of mechanical alloying and heat treatment. Finally, the evolution of the microstructure during milling and annealing was combined to propose an optimal processing route in order to obtain a α solid solution.

As a consequence of the habituation to low levels of dichlobenil （DCB）, cultured maize cells presented an altered hemicellulose cell fate with a lower proportion of strongly wall-bound hemicelluloses and an increase in soluble extracellular polymers released into the culture medium. The aim of this study was to investigate the relative molecular mass distributions of polysaccharides as well as phenolic metabolism in cells habituated to low levels of DCB （1.5 μM）. Generally, cell wall bound hemicelluloses and sloughed polymers from habituated cells were more homogeneously sized and had a lower weight-average relative molecular mass. In addition, polysaccharides underwent massive cross-linking after being secreted into the cell wall, but this cross-linking was less pronounced in habituated cells than in non-habituated ones. However, when relativized, ferulic acid and p-coumaric acid contents were higher in this habituated cell line. Feasibly, cells habituated to low levels of DCB synthesized molecules with a lower weight-average relative molecular mass, although cross-linked, as a part of their strategy to compensate for the lack of cellulose.

To improve food quality, the use of olive leaf extracts has been an emergent strategy that needs to be study in different scenarios. Certain local olive varieties are waiting to be discovered as potential by-product sources, in which a Tunisian variety named ‘Chetoui’ can be pointed out. The use of this variety at different tree ages to elaborate olive leaf extracts (OLE) in different solvents has been the main procedure to study during this assay. Different OLE concentrations were prepared in order to evaluate its effect in contaminants such as acrylamide. Adult ‘Chetoui’ OLE presented a richer phenolic content that is younger homonym. Principal phenols like hydroxytyrosol, tyrosol, oleuropein and luteolin-7-O-gluvoside presented higher levels for both tree ages. In terms of extractants, the most effective was Methanol, having concentrations for oleuropein, hydroxytyrosol and Luteolin-7-O-glucoside of 175331, 32433 and 10688 mg 100 g−1 respectively. Hexane was the least successful solvent, having no concentration for plenty of the phenols. Acrylamide concentration was deeply affected for the OLE presence for every extract concentration, being OLE (1:10) and OLE (1:10 + HTy) the additions with a better performance followed by OLE (1:100). A sensory analysis was performed finding out that OLE (1:100) was the most appealing for the consumer when adding it to table olives. The current research attempts to discover new applications for local varieties, using by-products to enhance oxidized black table olives added value. Finally, market products would become healthier, safer and with better quality to be released in the food industry.
