Modern industry demands high throughput with superior quality, a balance that is maintained through robust process control. SEM and TEM tools with dedicated automation software provide rapid, multi-scale information for process monitoring and improvement. Quality control and failure analysis Quality control...
Year-round, CH\(_4\) ebullition was highest at the central section of the river bed, represented by sites B and C (Fig. 5). Our initial hypothesis was that highest ebullitive CH\(_4\) fluxes were to be expected at the undercut slope (site A), because sediment incubation studies sug...
However, previous experimental studies have shown that applying such surface functionalization toγ-alumina ceramic membranes and mesoporous glass membranes significantly reduces the gas flow6,7,8. It was shown that length and density of the functional molecules are the determining factors which impact t...

Ultimately, your goal when you use the scientific method is to: Find a cause-and-effect relationship by asking a question about something you observed Collect as much evidence as you can about what you observed, as this can help you explore the connection between your evidence and what you ...
the CE is a broader notion in that it promotes not only recycling but also the imperatives to reject, reduce, reuse, refurbish, and remanufacture. At the same time, and importantly, with the transmutation of the notion of a recyclingsocietyinto a circulareconomy, the economic frame comes to ...

1). The climate is humid temperate with precipitations occurring all year round. The dominant vegetation is a grass steppe dominated by Stipa, Piptochaetium, Poa, Eragrostis, and Aristida, wild straws (Melica), wisps (Briza), and bromes (Bromus)26. Traditionally, this region was devoted to...
The annual accumulated temperature over 10 °C is 2400–3500 °C. At 3800 m above sea level, the air temperature gradually decreases with the elevation and stays below 0 °C year-round and above the snow line33. The surrounding deserts and dry areas reflect the characteristic aridity of ...
