Influence of the milling parameters on the mechanical work intensity in planetary mills
(Elsevier, 2013)
The formation of ZnSe via a mechanically-induced self-sustaining reaction (MSR) from a Zn/Se mixture showed that only size reduction and mixing of the reactants without product formation occurred during the induction period ...

Study of Zalema Grape Pomace: Phenolic Composition and Biological Effects in Caenorhabditis Elegans
(American Chemical Society, 2013)
The phenolic composition of the extractable fraction of Zalema grape pomace has been analyzed by HPLC-DAD-MS and consisted of mainly flavanols and flavonols (122.75 and 23.11 mg/100 g dry pomace, respectively). The antioxidant ...

Mechanochemical synthesis of ZrB2-SiC-ZrC nanocomposite powder by metallothermic reduction of zircon
(Elsevier, 2013)
Aluminium and magnesium were used in the M/ZrSiO4/B 2O3/C (M = Al, Mg) system to induce a mechanically induced self-sustaining reaction (MSR). Aluminium was not able to reduce the system to the desired products, and the ...

Cluster of genes that encode positive and negative elements influencing filament length in a heterocyst-forming cyanobacterium
(American Society for Microbiology, 2013)
The filamentous, heterocyst-forming cyanobacteria perform oxygenic photosynthesis in vegetative cells and nitrogen fixation in heterocysts, and their filaments can be hundreds of cells long. In the model heterocyst-forming ...

Mechanosynthesis of nanocrystalline ZrB2-based powders by mechanically induced self-sustaining reaction method
(Elsevier, 2013)
Preparation of nanocrystalline ZrB2-based powder by aluminothermic and magnesiothermic reductions in M/ZrO2/B 2O3 (M = Al or Mg) systems was investigated. In this research, high energy ball milling was employed to persuade ...

Liquid-phase sintering of Ti(C,N)-based cermets. the effects of binder nature and content on the solubility and wettability of hard ceramic phases
(Elsevier, 2013)
Different commercial TiC-TiN/Co/Ni mixtures were used as raw materials for Ti(C,N) cermets, and the effects of the sintering parameters (binder content, binder nature, sintering time and additives) on the final hard ceramic ...

Spark plasma sintering of TixTa1-xC0.5N0.5-based cermets: Effects of processing conditions on chemistry, microstructure and mechanical properties
(Elsevier, 2013)
Nanometric powdered TixTa1-xC0.5N0.5-based cermets were fabricated using a mechanically induced self-sustaining reaction and consolidated by spark plasma sintering. Highly dense cermets were obtained, and their chemistry, ...

Effect of sintering time on the microstructure and mechanical properties of (Ti,Ta)(C,N)-based cermets
(Elsevier, 2013)
Complete solid-solution cermets based on titanium-tantalum carbonitride using a starting nominal composition with 80 wt.% of (Ti0.8Ta 0.2)(C0.5N0.5) and 20 wt.% of Co were performed by pressure-less sintering at 1550 C for ...

Kinetic studies in solid state reactions by sample-controlled methods and advanced analysis procedures
(Akadémiai Kiadó (Budapest), 2013)
A comparative study of both conventional rising temperature and sample-controlled methods, like constant rate thermal analysis (CRTA), is carried out after analyzing a set of solid state reactions using both methods. It ...

Sedimentological and geomorphological imprints of Holocene tsunamis in southwestern Spain: An approach to establish the recurrence period
(Elsevier, 2013)
This paper reviews the sedimentological and geomorphological imprints of prehistoric and historical tsunamis in the four main estuaries of SW Spain. These imprints include beach erosion, filling of intertidal channels, ...
