Double-sided three-dimensional porous silicon chips, 6 mm x 6 mm, covered with a 40 nm gold (nano)layer, were fabricated from a porous silicon wafer. Scanning electron microscopy along with electrochemical characterisation showed sample conductivity, mechanical stability, and high surface area of the thus fabricated devices, viz. 10 times higher electrochemically active surface area compared to th
The development of blood cells from hematopoietic stem cells in the bone marrow is dependent on communication with bone marrow stroma cells, making these cells central for the appropriate regulation of hematopoiesis. To identify transcription factors that may play a role in gene regulation in stroma cells, we performed comparative gene expression analysis of fibroblastic NIH3T3 cells, unable to su
A new approach for one‐stage facile membrane modification during non‐solvent induced phase separation (NIPS)‐process is proposed. The novelty of this study is that cheap and commercially available anionic high molecular polyacrylamide‐based flocculant (AHMPF) is applied for the first time as an additive to coagulation bath (CB). The series of polyethersulfone membranes were prepared using 0.05–0.3
This work was conducted to study the potential of molecularly imprinted polymers (MIPs) for the removal of oestradiol at trace concentrations (1 ppm - 1 ppb). An MIP synthesised with 17 beta-oestradiol as template was compared to non-imprinted polymers (NIP) synthesised under the same conditions but without template, a commercial C18 extraction phase and granulated activated carbon. At 1 ppb,oestr
Stem cell treatments for neurodegenerative diseases are expected to reach clinical trials soon. Most of the approaches currently under development involve transplantation of immature progenitors that subsequently undergo phenotypic and functional maturation in vivo, and predicting the long-term graft outcome already at the progenitor stage remains a challenge. Here, we took an unbiased approach to
The scope of this Master Thesis project is divided in two parts. In the first part, the objective is to characterise various strains of Azotobacter vinelandii under diazotrophic conditions with regards to growth rate and production of metabolites, such as ammonium or PHB. This will allow for an assessment on which nitrogen fixing strain displays the most promising results for use in the second par
The past years have seen increasing interest in nonlinear optical microscopic imaging approaches for the investigation of diseases due to the method's unique capabilities of deep tissue penetration, 3D sectioning and molecular contrast. Its application in clinical routine diagnostics, however, is hampered by large and costly equipment requiring trained staff and regular maintenance, hence it has n
In today’s city branding field, a gap exists between research and practice. A gap made more evident since the field has moved to prefer a participative approach, where stakeholders are more acknowledged as an important part of the city branding process, illustrating the little knowledge of stakeholders’ own practices. This study undertakes a mission of moving forward in the research field by shedd
Variational Mode Decomposition (VMD) is a powerful formalism for the time-scale analysis of vibration signals from rotating machinery. However, its performance is often compromised by complex parameter configuration, where subjective manual tuning leads to mode mixing or information loss. In this study, we present a physics-guided framework that generalizes VMD optimization across diverse operatin
Historically, inhabitants have always altered their domestic spaces to adapt to different environmental conditions and to meet personal needs. Especially in rural dwellings, lowtech but very effective and simple ways of adaptations have been and are still in use. These methods stand more than ever diametral to the way we dwell and use our domestic spaces today. All the building ele- ments are gett
With the vigorous development of the electric vehicle industry, there is an increasing demand for high-capacity, high-stability batteries, and higher requirements are also placed on clean, non-toxic, and efficient battery production processes. The electrode is one of the most important components in lithium-ion batteries. It determines the capacity and overall performance of the battery. The fabri
Aim: Grass-yellow butterflies (Eurema) are a group of pantropical Pieridae distributed throughout Asia, Australasia, Africa and the New World. However, little is known about their diversification, including the biogeographic mechanism(s) explaining their circumglobal distribution. We present the first densely sampled, time-calibrated phylogeny and biogeographic reconstruction of grass-yellows to c

A reduced number or dysfunction of inhibitory interneurons is a common contributor to neurodevelopmental disorders. Therefore, cell therapy using interneurons to replace or mitigate the effects of altered neuronal circuits is an attractive therapeutic avenue. To this end, more knowledge is needed about how human stem cell-derived GABAergic interneuron-like cells (hdINs) mature, integrate, and func
Over the past two decades, intensive research efforts have been devoted to suppressions of Auger recombination in metal-chalcogenide and perovskite nanocrystals (PNCs) for the application of photovoltaics and light emitting devices (LEDs). Here, we have explored dodecahedron cesium lead bromide perovskite nanocrystals (DNCs), which show slower Auger recombination time compared to hexahedron nanocr
