(author), Kumar, Dhruv (author), Ghosh, Ashok Kumar (author)Reportedly, 300 million people worldwide are affected by the consumption of arsenic contaminated groundwater. India prominently figures amongst them and the state of Bihar has shown an upsurge in cases affected by arsenic poisoning. Escalated arsenic content in blood, leaves 1 in every 100 human being highly vulnerable to being affected by...journal article 2021

Butsch, Carsten (author), Chakraborty, Shreya (author), Gomes, S.L. (author), Kumar, Shamita (author), Hermans, L.M. (author)India’s urbanisation results in the physical and societal transformation of the areas sur-rounding cities. These periurban interfaces are spaces of flows, shaped by an exchange of matter, people and ideas between urban and rural spaces—and currently they are zones in transition. Periur-banisation processes result inter alia in changing water...journal article 2021

(author)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....journal article 2021

Kumar, Kavisha (author)A 3D city model is a digital representation of the spatial features in an urban<br/>environment. Buildings, terrain, vegetation, water bodies, etc. all form an integral part of a 3D city model. The possibility to enrich these city models with additional application-specific information, whether new semantics or geometry, further increases their...doctoral thesis 2020

Kumar, Karishma (author)Detailed imaging of blood flow may improve the understanding of brain functions. The state-of-the-art non-invasive flow imaging of the brain is limited to a one-dimensional Doppler setting. We propose a method to estimate the two-dimensional flow vector in the fine vascular network of the brain by using a speckle tracking technique. The...master thesis 2020

Stoter, J.E. (author), Peters, R.Y. (author), Commandeur, T.J.F. (author), Dukai, B. (author), Kumar, Kavisha (author), Ledoux, H. (author)Noise is one of the main problems in urban areas. To monitor and manage noise problems, governmental organisations at all levels are obliged to regularly carry out noise studies. The simulation of noise is an important part of these studies. Currently, different organisations collect their own 3D input data as required in noise simulation in a...journal article 2020

(author)Zeolite 13X and 5A supported Ni catalysts were synthesized for CO<sub>2</sub> methanation using the evaporation impregnation method. The influence of using different Ni precursors (nitrate, citrate, and acetate) as well as calcination temperatures on the catalyst properties and performance were investigated.

Ravi, A.M. (author), Kumar, A. (author), Herbig, Michael (author), Sietsma, J. (author), Santofimia, Maria Jesus (author)The rate of bainite formation depends on several factors such as austenite grain size, decomposition of austenite into other phases and austenite composition. Although studies have been carried out to understand various factors affecting bainite formation, open lines of investigation still remain. In this work, the effect of ferrite formation...journal article 2020

(author)Power Doppler (PD) imaging has become a staple in high frame rate ultrasound imaging due to its ability to image small vessels and slow-moving flows, such as in the case of imaging blood flow in the brain. Alternatively, color Doppler (CD) can be used to determine the one-dimensional directional information of the blood scatterers. This can help...conference paper 2020

Koeze, D.J. (author), Hong, Lingtjien (author), Kumar, Abhishek (author), Tighe, B.P. (author)Numerous soft materials jam into an amorphous solid at a high packing fraction. This nonequilibrium phase transition is best understood in a model system where particles repel when they overlap. Recently, however, it was shown that introducing any finite amount of attraction between particles changes the universality class of the transition....journal article 2020

(author)Adsorption behavior of surfactants to rock surfaces is an important issue in oil recovery, especially in the process of surfactant flooding. The surfactant loss through adsorption to rock surfaces makes such process economically less feasible.
