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

van Wee, R.G. (author), Filius, M. (author), Joo, C. (author)Single-molecule localization microscopy (SMLM) is a potent tool to examine biological systems with unprecedented resolution, enabling the investigation of increasingly smaller structures. At the forefront of these developments is DNA-based point accumulation for imaging in nanoscale topography (DNA-PAINT), which exploits the stochastic and...review 2021

Hingot, V. (author), Chavignon, A. (author), Heiles, B.G. (author), Couture, O. (author)The resolution of an imaging system is usually determined by the width of its point spread function and is measured using the Rayleigh criterion. For most system, it is in the order of the imaging wavelength. However, super resolution techniques such as localization microscopy in optical and ultrasound imaging can resolve features an order of...journal article 2021

Saeedifar, M. (author), Saghafi, Hamed (author), Mohammadi, Reza (author), Zarouchas, D. (author)The present study evaluates the toughening capability of electrospun PA66 nanofibers for carbon/epoxy composite laminates subjected to mode II loading conditions at elevated temperatures. The Dynamic Mechanical Analysis (DMA) test showed that the glass transition temperature of the produced nanofibers is in a range of ∼60–80 °C. Accordingly,...journal article 2021

Roest, Laurien I. (author), van Heijst, S.E. (author), Maduro, L.A. (author), Rojo, Juan (author), Conesa Boj, S. (author)Exploiting the information provided by electron energy-loss spectroscopy (EELS) requires reliable access to the low-loss region where the zero-loss peak (ZLP) often overwhelms the contributions associated to inelastic scatterings off the specimen. Here we deploy machine learning techniques developed in particle physics to realise a model...journal article 2021

Hari, S. (author), Trompenaars, P. H.F. (author), Mulders, J. J.L. (author), Kruit, P. (author), Hagen, C.W. (author)High resolution dense lines patterned by focused electron beam-induced deposition (FEBID) have been demonstrated to be promising for lithography. One of the challenges is the presence of interconnecting material, which is often carbonaceous, between the lines as a result of the Gaussian line profile. We demonstrate the use of focused electron...journal article 2021

(author), Ghatkesar, M.K. (author)Micro- and nano-patterns are gaining increasing attraction in several fields ranging from nanoelectronics to bioengineering. The mechanical properties of the nanostructures (nanopillars, nanotubes, nanowires, etc.) are highly relevant for many applications but challenging to determine. Existing mechanical characterization methods require...journal article 2021

(author)Septin GTP-binding proteins contribute essential biological functions that range from the establishment of cell polarity to animal tissue morphogenesis. Human septins in cells form hetero-octameric septin complexes containing the ubiquitously expressed SEPT9 subunit (also known as SEPTIN9). Despite the established role of SEPT9 in mammalian...journal article 2021

Quan, D. (author), Moloney, Peter (author), Carolan, Declan (author), Abourayana, Hisham (author), Ralph, Calvin (author), Ivankovic, Alojz (author), Dowling, Denis (author), Murphy, Neal (author)This work studied the effects of adding short basalt fibers (BFs) and multi-walled carbon nanotubes (MWCNTs), both separately and in combination, on the mechanical properties, fracture toughness, and electrical conductivity of an epoxy polymer. The surfaces of the short BFs were either treated using a silane coupling agent or further...journal article 2021

(author)This work concerns the fatigue behavior at three different temperature conditions (−40, 20, and 80°C) and the addition of multiwalled carbon nanotube (MWCNT) into a carbon-fiber reinforced poly(ether-imide) composite. The incorporation of MWCNT into the composite increased the tensile strength and Young's modulus by up 5 and 2%, respectively....journal article 2020

Janssen, V.A.E.C. (author)This thesis describes research into the interaction between electrons and various (pseudo) two-dimensional materials. This research is using two approaches: in Chapters 3 and 4 a low-energy electron microscope is used, and in Chapters 5 and 6 transport properties are studied. Chapter 1 introduces the concept of a two-dimensional material. First,...doctoral thesis 2020

Büke, F. (author)Bacteria have been an integral part of human life since the ancient times either as cooperative tenants living in and around us or as constant threats to our health and wellbeing. Since prehistoric times we unknowingly used them as tools of fermentation and fought against them with haphazardly discovered natural remedies. Today, after more than...doctoral thesis 2020

van Rooij, J. (author)Optical imaging is the imaging of objects with visible light. It is a tool often used for diagnostic purposes, such as in biomedical and material sciences. Digital holography is an optical imaging technique that captures and images the amplitude as well as the phase (the complex amplitude) of the lightwave. An advantage is that the complex...doctoral thesis 2020

Deb Roy, S. (author)The basis of this thesis has been the curiosity, however modest, to understand how DNA replication happens in vivo, particularly during the onset of DNA damage and beyond. DNA damage is a recurring phenomenon, which a (bacterial) cell faces in its lifetime from the environment or even its inherent metabolism. While we understand much about...doctoral thesis 2020

Agbana, T.E. (author)Malaria remains an important cause of high morbidity and mortality worldwide. According to World Health Organisation (WHO) malaria report for 2017, malaria accounted for the death of 435,000 people. It is the leading cause of death among pregnant women and little children. 11% of maternal and 20% of under–five deaths are attributed to malaria...doctoral thesis 2020

(author)Chemical vapour deposition (CVD) is a promising method for producing large-scale graphene (Gr). Nevertheless, microscopic inhomogeneity of Gr grown on traditional metal substrates such as copper or nickel results in a spatial variation of Gr properties due to long wrinkles formed when the metal substrate shrinks during the cooling part of the...journal article 2020

van Kessel, L.C.P.M. (author), Huisman, T.A. (author), Hagen, Cornelis W. (author)Background: Line-edge roughness (LER) is often measured from top-down critical dimension scanning electron microscope (CD-SEM) images. The true three-dimensional roughness profile of the sidewall is typically ignored in such analyses. Aim: We study the response of a CD-SEM to sidewall roughness (SWR) by simulation. Approach: We generate...journal article 2020
