There is increasingly robust evidence that hypertension is a chronic kidney disease (CKD) risk factor and is strongly predictive of rapid kidney function decline (RKFD) in elderly individuals. 1–3 To date, however, there have been very few longitudinal studies examining how hypertension relates to RKFD risk in very elderly adults (>80 years old) …
WebDual-phase molten salt-ceramic membranes show high permselectivity for CO2 when molten carbonate is supported in a porous oxygen-ion and/or electron conductor. In this arrangement, the support likely contributes to permeation. Thus, if one is to understand and ultimately design membranes, it is also important to perform experiments with an ...
