Molecular self-assembly of organic building blocks has often been used for fabricating complex functional surfaces. A sizeable part of this discipline consists of understanding the complexity of molecular recognition processes transpiring during the assembly process which occurs at the interface between an organic liquid and a crystalline solid. ln the last two decades, a wide variety of structurally diverse molecular layers have been ...
This research focuses on using chirality as a tool to study different aspects of supramolecular self-assembly of molecular building blocks on the highly ordered pyrolytic graphic (HOPG), at the liquid-solid interface. A well-known class of molecules in the field of supramolecular assembly on surfaces, alkoxylated dehydrobenzo[12]annulene (DBA) derivatives, are selected as the objects of study, as in addition to the vast amount of information ...
Molecular self-assembly has been widely used as tool for the modification and functionalization of surfaces, whereby in many cases pristine surfaces like highly-oriented pyrolytic graphite (HOPG) were used as substrates to study supramolecular self-assembly from solution. Scanning probe techniques enable the study of these molecular layers with sub-molecular resolution. Similar to crystallization in bulk, supramolecular self-assembly is known ...
The aim of this project is to study the self-assembly and phase behavior of liquid crystalline cellulose mesophases with advanced light scattering techniques. These techniques use harmonic light scattering, whereby very intense laser light generates so-called harmonics. For example, laser light of 900 nm will generate new wavelengths at 450 nm (second harmonic) and 300 nm (third harmonic). These harmonics enable us to characterize the local ...
Molecular self–assembly, a promising strategy for modification of surfaces on nanometer scale, is of great importance for the development of functional materials and in 2D crystal engineering. Understanding the complexity of molecular mechanisms controlling the self-assembly process at the interface between a liquid and a crystalline solid, i.e. the liquid-solid interface (LSI) presents the foundation for rational design and fine-tuning of ...
In a biomimetic approach,we aim to create hierarchical multi-functionalone-, two- and three-dimensional structures with controlled long-range order through self-assembly of multifunctional rodlike nanoparticles. To achieve this, we will modify the surface of ribbon-like cellulose nanocrystals at their three distinct surface functionalities: primary and secondary hydroxyl groups on the lateral surfaces and aldehydes at the extremities. These ...
My research mainly focuses on the development of hybrid self-assembled materials based on cellulose nanocrystals and inorganic nanoparticles.The thermodynamic driving forces and kinetic limitations of nanoparticle self-assembly to be able to create nanostructured materials in bulk and on surfaces with full control over the desired deposition pattern for applications in sensors, catalysts, and supercapacitors will be investigated.
Cellulose nanocrystals (CNCs) are a bio-based organic material that has unique properties, including renewability, biodegradability, sustainability, environmental friendliness, a high stiffness, an adaptable surface chemistry, chirality, a high surface area, and an anisotropic morphology. These properties make CNCs a promising candidate for applications in nanocomposites, films, paper products, membranes, cement, photonic devices, inks, and ...
Due to the higher demand for faster, low power IC chips for Internet-of-Things (IoT) and smart device applications, the need to increase the efficiency, performance and cost reduction of semiconductor chips is of paramount importance. Due to the decreasing rate of transistor scaling, 3D integration is viewed as a solution to build low power and high performance chips. One of the key requirements to enable 3D integration is high interconnect ...
