The current research work investigates the possibility of using machine learning models to deduce the relationship between WAAM (wire arc additive manufacturing) sensor responses and defect presence in the printed part. The work specifically focuses on three materials from the nickel alloy family – Inconel 718, Invar 36 and Inconel 625, and uses...

Arsenic is a common trace element in groundwater and its fate and transport are controlled by combination of (i) natural processes, including redox conditions, salinity and pH, (ii) sedimentary and geochemical environment, and (iii) anthropogenic influences such as groundwater extraction, managed aquifer recharge (MAR), Aquifer Thermal Energy...

This study aims to explore hydrogen production via alkaline water electrolysis using municipal effluent. The experiments were conducted in a flow cell electrolyzer using carbon fibre and Ni-foam as the anode, with another Ni-foam electrode employed as the cathode for all experiments. Synthetically prepared effluent and real municipal effluent...

Electroless nickel (Ni) immersion gold (Au), commonly referred to by the acronym ENIG, is the most common protective coating applied on the exposed copper (Cu) traces of printed circuit boards (PCBs). In this work, we elucidate the local corrosion mechanism of the ENIG-Cu system by applying microscopic, surface analysis and electrochemical...

Acceleration of the energy transition requires increased mining of materials. An important material for the energy transition is nickel, used in the stainless steel required for all energy infrastructure and an important component for both stationary batteries and batteries used in electric vehicles. Previous research has been done on the global...

Industrial-scale reforming of methane is typically carried out with an excess of oxidant to suppress coking of the catalyst. On the other hand, many academic studies on dry reforming employ a CO<sub>2</sub>/CH<sub>4</sub> ratio of unity to quickly observe coking which can be reduced by adding a catalyst promoter. In this work, Ni/Al<sub>2<...

Sub-nanometer zeolite 13X-supported Ni-ceria catalysts were synthesized for CO<sub>2</sub> methanation. XRD and SEM results show the structure and morphology of 13X zeolite after impregnation and calcination. Ce loading affected the catalysts’ metal dispersion, reducibility, basicity and acidity, and thence their activity and selectivity....

Catalyst passivation refers to the formation of a protective oxide layer on the active metal particles that prevents their oxidation when exposed to air. Common passivation procedures, when applied to Ni/ Al2O3 catalysts, typically result in a significant decrease of the overall Ni surface area and, accordingly, the catalytic activity....

The catalytic performances of TiO<sub>2</sub>-supported Ni catalysts for the methanation of CO<sub>2</sub> have been investigated using different crystalline phases of TiO<sub>2</sub> (rutile and anatase). The catalytic activity of Ni depends appreciably on the nature of the support. The rate for CO<sub>2</sub> hydrogenation decreases in the...

Zero Emission Fuels B.V. (ZEF) is developing an integrated micro-plant to produce methanol from captured CO2 and green Hydrogen produced via alkaline water electrolysis. The electrolysis unit represents one of the largest financial and energetic costs in the system and is required to operate at 166 mA/cm2 under 2 V. In order to decrease the...

The amino-terminal copper and nickel/N-terminal site (ATCUN/NTS) present in proteins and bioactive peptides exhibits high affinity towards Cu<sup>II</sup> ions and have been implicated in human copper physiology. Little is known, however, about the rate and exact mechanism of formation of such complexes. We used the stopped-flow and...

The battolyser concept is based on an old fashioned nickel iron battery, consisting of a positive nickel(oxy) hydroxide electrode and negative iron (hydroxide) electrode. Research has been performed on the structural changes of the nickel and iron electrode upon charge and discharge. A lot of research can be found for the nickel electrode, but...

Li and Na metals have the highest theoretical anode capacity for Li/Na batteries, but the operational safety hazards stemming from uncontrolled growth of Li/Na dendrites and unstable electrode-electrolyte interfaces hinder their real-world applications. Recently, the emergence of 3D conductive scaffolds aimed at mitigating the dendritic...

As the public demand for electric vehicles and consumer electronics grows at an exponential rate, traditional energy storage systems like lithium-ion batteries are proving to be insufficient. A potential candidate to replace these conventional systems is the lithium metal battery. However, replacing the anode of lithium-ion batteries with...

In the present work, the influence of strain on phase formation at the Al/Ni interface was investigated during cold roll bonding and annealing. A sandwich sample composed of an Al-Ni-Al stack was cold rolled with reductions in the range of 50% to 90%, followed by annealing at 450 °C for 60 min. The crystallography of the annealed sandwich...

We propose a new multi-microphone noise reduction technique for binaural cue preservation of the desired source and the interferers. This method is based on the linearly constrained minimum variance (LCMV) framework, where the constraints are used for the binaural cue preservation of the desired source and of multiple interferers. In this...

In the study described in this thesis, it is demonstrated that combined short-term and long-term energy storage in one device, the battolyzer, is possible. The battolyzer is a device that works as a rechargeable battery, and that is capable of performing highly efficient electrolysis with any excess electricity. The battolyzer was based on the...

Copper-nickel alloys are used for pipe systems that come into contact with seawater. These alloys are known under the group name cunifer alloys. In this research cunifer alloy CuNi10Fe (with 10 percent nickel) was investigated. The weld filler was a cunifer alloy with 30 percent nickel (CuNi30Fe). While generally there should be little corrosion...

The spin-Seebeck effect (SSE) in ferromagnetic metals and insulators has been investigated systematically by means of the inverse spin-Hall effect (ISHE) in paramagnetic metals. The SSE generates a spin voltage as a result of a temperature gradient in a ferromagnet, which injects a spin current into an attached paramagnetic metal. In the...
