In general, it can be stated that the lower the power class of the air-vehicle, the higher the potentials for fuel-cell propulsion since the core efficiency of gas turbines highly depend on the overall maximum power rating whereas fuel-cells hardly show sensitivities to scaling. However, the ...
SeO4, SO4, PO4) that are linked to one another solely by hydrogen bonds. At ambient temperatures, the rigid hydrogen-bonding network in such materials results in moderate proton conductivities (~10–5S/cm).8,18In a subset of compounds in this class, the material...

However, the class of hydrogenases targeted and the assays used in these studies did not include H2-evolving bidirectional [NiFe] hydrogen- ases harbored by phototrophic microorganisms. To our knowledge, no studies have examined the diversity of H2-evolving bidirectional [NiFe] hydro- genases in ...
A proof-of- concept is provided; it is shown that the design is applicable to two different systems (1 and 2, Fig. 1), and two different examples for each class are given. To the best of our knowledge, this paper constitutes the first example of a stable a-hydrogen piperidin-1- yl...
South Australia is a world-class region for wind and solar due to its location and natural resources [10]. South Australia’s shift to renewable energy production has led to a pipeline of wind, solar, and storage projects equalling 14,551 MW, or an investment of $A21.5 billion [10]. ...
Hypohalous acids are a very interesting class of compounds because they are often used as a model to analyze the competition between hydrogen and halogen bonding due to the presence of both the hydrogen bond donor and halogen bond donor in their structure. In this regard, complexes of hypo...
