Probing the hyperfine structure of Fe-based water-gas shift catalysts

Hydrogen gas is an essential reagent in numerous industrial processes including ammonia synthesis. Ammonia is a key intermediate in the synthesis of nitrogen-based fertilisers, e.g. nitrates and urea. According to recent estimates (2008), approximately half of the world population is fed by nitrogen-based fertilisers of synthetic origin....

In Situ Study of Hydrogen Permeable Electrodes for Electrolytic Ammonia Synthesis Using Near Ambient Pressure XPS

Hydrogen permeable electrodes can be utilized for electrolytic ammonia synthesis from dinitrogen, water, and renewable electricity under ambient conditions, providing a promising route toward sustainable ammonia. The understanding of the interactions of adsorbing N and permeating H at the catalytic interface is a critical step toward the...

Insights into oil recovery mechanism by Nothing-Alternating-Polymer (NAP) concept

This paper introduces new oil recovery mechanisms for oil recovery by polymer injection in heavy oil reservoirs with strong bottom aquifers. Due to unfavorable mobility ratio between aquifer water and oil and the development of the sharp cones significant amount of oil remains unswept. To overcome these issues, for the case demonstrated in...

Quality Assessment of GNSS/IMU derived NAP heights: using RILA and RDNAPTRANS™2018

The purpose of this thesis is to do quality assessment of GNSS/IMU derived NAP heights for The Netherlands (NAP) using Fugro RILA technique and the RDNAPTRANS2018 published by Rijkswaterstaat. The use of Global Navigation Satellite System (GNSS) is growing rapidly in order to determine the position (both horizontal and vertical). However, the...

Design of a power nap facility for night shift workers

The number of people working night shifts has been steadily increasing over the past 20 years. Although shift workers have known this for a long time already from first-hand experience, the Dutch national institute for public health and the environment has recently published advice to minimize night (shift) work, as it is detrimental to the...

NAP to EVRS: a re-evaluation of the Dutch input and its impact on the realization of the European Vertical Reference System

Double degree of Master of Science in Applied Geophysics at Delft University of Technology, ETH Zürich and RWTH Aachen University. - In 2004, Rijkswaterstaat provided geopotential differences between the benchmarks of the Normaal Amsterdams Peil (NAP) network to the Bundesamt für Kartographie und Geodäsie (BKG) for the realization of the...

Ontwerp veldproef snelle paaltest Waddinxveen: Deel 1: Management Summary

Medio 2007 wordt een veldproef georganiseerd in Waddinxveen in het kader van de validatie van de snelle paaltest. Initiatiefnemers van de proef is de DC/CUR commissie ‘validatie snelle paaltest’. Tijdens deze veldproef worden twee prefab betonpalen beproefd op met een statische en een snelle paaltest. De snelle paaltest wordt uitgevoerd door de...

Studie betreffende de herziening van de Noordzee Reductiekaart

Er bestaat bij de Dienst der Hydrografie behoefte aan een nauwkeurige afweging welke analyses uit het getijbestand van de Dienst wél en welke niet bij de samenstelling van de reductiekaart gebruikt moeten worden. Daarnaast is een zekere toekomstvisie met betrekking tot samenstelling en gebruik van de reductiekaart gewenst. In dit rapport wordt...
