Advanced Energy Materials, EarlyView.This work uncovers the atomic‐scale origins of exceptional HER performance in amorphous Ni(OH)2 nanosheets by combining atom probe tomography, DFT simulations, and operando spectroscopy. We identify distinct short‐range‐order motifs that accelerate water dissociation, proton transport, and hydrogen adsorption. Embedding Pt single atoms further enhances

Theoretical and practical aspects of variography: in particular, estimation and modelling of semi-variograms over areas of limited and clustered or widely spaced data in a two-dimensional South African gold mining context. [PDF]
, 2012 This thesis provides a detailed study of the semi-variogram. Included is a thorough presentation of the theory of semi-variograms, ranging from the probabilistic model of geostatistics to validity, estimation and modelling of the semi-variogram.
