Mass Transport Limitations in Electrochemical Conversion of CO2 to Formic Acid at High Pressure

Ramdin, M. (author), Vlugt, T.J.H. (author), Selvaraj, S. (author)

Mass transport of different species plays a crucial role in electrochemical conversion of CO (Formula presented.) due to the solubility limit of CO (Formula presented.) in aqueous electrolytes. In this study, we investigate the transport of CO (Formula presented.) and other ionic species through the electrolyte and the membrane, and its...

Observed changes in the Earth’s dynamic oblateness from GRACE data and geophysical models

Sun, Y. (author), Ditmar, P. (author), Riva, R. (author)

A new methodology is proposed to estimate changes in the Earth’s dynamic oblateness (?J2 or equivalently, ?5??C20) on a monthly basis. The algorithm uses monthly Gravity Recovery and Climate Experiment (GRACE) gravity solutions, an ocean bottom pressure model and a glacial isostatic adjustment (GIA) model. The resulting time series agree...

The use of STEM imaging to analyze thickness variations due to electromigration-induced mass transport in thin polycrystalline nanobridges

Rudneva, M. (author), Kozlova, T. (author), Zandbergen, H.W. (author)

Scanning transmission electron microscopy (STEM) imaging is applied to analyze the electromigration-induced thickness variations of thin polycrystalline films, It is shown that a high angle annular dark field (HAADF) detector is required to minimize the effect of diffraction contact. A further reduction of the diffraction contrast can be...

Understanding data noise in gravity field recovery on the basis of inter-satellite ranging measurements acquired by the satellite gravimetry mission GRACE

Ditmar, P. (author), Teixeira da Encarnacao, J. (author), Hashemi Farahani, H. (author)

Spectral analysis of data noise is performed in the context of gravity field recovery from inter-satellite ranging measurements acquired by the satellite gravimetry mission GRACE. The motivation of the study is two-fold: (i) to promote a further improvement of GRACE data processing techniques and (ii) to assist designing GRACE follow-on missions...

CFD-methods applied to dispersed particle flow within melt pools during laser induced surface modification processes of ceramics

Rohde, M. (author)

Laser surface melting and alloying are important techniques to improve the properties of a material locally without affecting the bulk. In ceramic components these methods can be used to optimise the fracture toughness, friction and wear but also the thermal and electrical conductivity [1]. In order to predict the results of the modification...
