Passive NOx adsorption (PNA) is a novel technology to control emissions during cold start. However, the recent generation of PNA material, Pd/zeolite, suffers from major degradation under high CO concentrations. In this work, we developed form Pd/SSZ-13 by using freeze-drying process after incipient wetness impregnation. This showed better stability than sample synthesized common process. Sever...

Abstract Polymer coatings on cellulosic fibres are widely used to enhance the natural fibre properties by improving, for example, hydrophobicity and wet strength. Here, we investigate effects of a terpolymer P(S-co-MABP-co-PyMA) coating cotton linters eucalyptus improve resistance cellulose against wetness. Coated uncoated were characterised using scanning electron microscopy, contact angle mea...

Runoff events play an important role in nitrate export from catchments, but the variability of patterns between and catchments is high dominant drivers remain difficult to disentangle. Here, we rigorously asses if detailed knowledge on runoff event characteristics can help explain this variability. To end, conducted a long-term (1955–2018) classification using hydro-meteorological data, includi...

Abstract At present, the Basin and Range of western USA is arid, but geologic studies show evidence past wetness. The timing these wetter conditions reveals a close association with glacial conditions. This has led to hypothesis causal link between climate regional wetness, poor age control on onset wetness thwarts test this hypothesis. Here we determine start most recent interval persistent in...
