van Esch, M.S. (author), Bloemendal, Martin (author), Hartog, Niels (author), Vardon, P.J. (author)Aquifer Thermal Energy Storage (ATES) is mostly used to store heat and cold in groundwater at relatively low temperatures for heating and cooling buildings. These systems emit 3-4 times less CO2 when compared to gas heating, but still require substantial amounts of electricity to run due to the use of a heat pump ( 60%). In typical ATES systems...abstract 2022

Maiullari, D. (author), Mosteiro-Romero, Martin (author), van Esch, M.M.E. (author)In the design practice simulation methods are already widely used to support the understanding of energy performance and to help designers in reducing energy demand during the design process. However, energy simulation tools are largely limited to the individual building level, and urban microclimate conditions and<br/>variations in local wind,...conference paper 2018

Maiullari, D. (author), van Esch, M.M.E. (author), van Timmeren, A. (author)Morphological characteristics of cities significantly influence urban heat island intensities and thermal responses to heat waves. Form attributes such as density, compactness, and vegetation cover are commonly used to analyse the impact of urban morphology on overheating processes. However, the use of abstract large-scale classifications...journal article 2021

(author)Cells can react to their environment by changing the activity of enzymes in response to specific chemical signals. Artificial catalysts capable of being activated by chemical signals are rare, but of interest for creating autonomously responsive materials. We present an organocatalyst that is activated by a chemical signal, enabling temporal...journal article 2017

(author)Atherosclerotic arteries are commonly treated using drug-eluting stents (DES). However, it remains unclear whether and how the properties of atherosclerotic plaque affect drug transport in the arterial wall. A limitation of the currently used atherosclerotic animal models to study arterial drug distribution is the unpredictability of plaque...journal article 2021

Piskorz, T.K. (author), De Vries, A. H. (author), van Esch, J.H. (author)In recent years, computational methods have become an essential element of studies focusing on the self-assembly process. Although they provide unique insights, they face challenges, from which two are the most often mentioned in the literature: the temporal and spatial scale of the self-assembly. A less often mentioned issue, but not less...journal article 2021

Lakshminarayanan, Vasudevan (author), Chockalingam, Cindhuja (author), Mendes, E. (author), van Esch, J.H. (author)Properties such as shear modulus, gelation time, structure of supramolecular hydrogels are strongly dependent on self-assembly, gelation triggering mechanism and processes used to form the gel. In our work we extend reported rheology analysis methodologies to pH-triggered supramolecular gels to understand structural insight using a model...journal article 2021

(author)By equipping mutually incompatible carboxylic acid and proline catalytic groups with different self-assembling motives we have achieved self-sorting of the resulting catalytic gelators, namely SucVal8 and ProValDoc, into different supramolecular fibers, thus preventing the acidic and basic catalytic groups from interfering with each other. The...journal article 2016

(author)ConspectusOne often thinks of catalysts as chemical tools to accelerate a reaction or to have a reaction run under more benign conditions. As such, catalysis has a role to play in the chemical industry and in lab scale synthesis that is not to be underestimated. Still, the role of catalysis in living systems (cells, organisms) is much more...journal article 2016

(author), Raffy, G. (author), Del Guerzo, A. (author), van Esch, J.H. (author)The orthogonal self-assembly of multiple components is a powerful strategy towards the formation of complex biomimetic architectures, but so far the rules for designing such systems are unclear. Here we show how to identify orthogonal self-assembly at the supramolecular level and describe guidelines to achieve self-sorting in self-assembled...journal article 2016
