Abstract The corrosion and passivation behavior of the as-cast CoCrFeNiMo x ( = 0, 0.2, 0.4, 0.6, 0.8, 1.0) high entropy alloys (HEAs) are investigated. With addition Mo, increasing Mo Cr riched σ phase precipitates from primary FCC phase. resistance HEAs strongly depends on structure passive film. Generally, promotes selective dissolution enrichment 2 O 3 in film, former deteriorates while lat...

Diabases, pillow lavas and basaltic flows in the Nain-Dehshir ophiolites are marked with flat to slightly depleted pattern in REE chondrite-normalized diagram and are characterized by depletion in HFSE and enrichment in LILE. This geochemical behavior can be considered for lavas erupted in arc-related environments. Clinopyroxene in these rocks shows low content of TiO2 and resemble those found ...

Ecosystem engineers change abiotic conditions, community assembly and ecosystem functioning. Consequently, their loss may modify thresholds of ecosystem response to disturbance and undermine ecosystem stability. This study investigates how loss of the bioturbating lugworm Arenicola marina modifies the response to macroalgal detrital enrichment of sediment biogeochemical properties, microphytobe...

A culture method to detect non-O157 Shiga toxin-producing Escherichia coli (STEC) was optimized in this study. The finished dairy compost with 30% moisture content was inoculated with a cocktail of six non-O157 STEC serovars at initial concentrations of 1 to 100 CFU/g. Afterward, non-O157 STEC cells in the inoculated dairy compost were enriched by four methods, followed by plating onto cefixime...

Contextualist theories of utterance interpretation posit a process of free pragmatic enrichment that contributes ‘unarticulated constituents’ of the explicit content of utterances. In this paper, I address the main concern about this process, which is that it is not sufficiently constrained, and appears to allow for enrichments that clearly do not occur. One variety of this overgeneration objec...

A facile in situ vapour phase hydrothermal (VPH) surface doping approach has been developed for fabrication of high performance S-doped Co3O4 electrocatalysts with an unprecedentedly high surface S content (>47%). The demonstrated VPH doping approach could be useful for enrichment of surface active sites for other metal oxide electrocatalysts.

Indicators of ecosystem structures and processes are important in estuarine health studies but are rarely assessed simultaneously. Organic enrichment affects the abundance and diversity of meioand macrofauna, but its impact on foodweb dynamics is less well known.We used amanipulative field experiment combining stable isotope enrichment with compartmental modelling (WinSAAM) and ecological netwo...

Triacylglycerol (TAG) storage and turnover rates in the intact, beating rat heart were determined for the first time using dynamic mode (13)C- NMR spectroscopy to elucidate profound differences between hearts from diabetic rats (DR, streptozotocin treatment) and normal rats (NR). The incorporation of [2,4,6,8,10,12,14,16-(13)C(8)]palmitate into the TAG pool was monitored in isolated hearts perf...
