A comprehensive experimental study of five fundamental phenothiazine geometries increasing the diversity of the phenothiazine dye class for dye-sensitized solar cells
(Journal article; Peer reviewed, 2019)Phenothiazine is a versatile scaffold frequently used in both pharmaceutical and photovoltaic applications. Still, the structural diversity within the class of phenothiazine sensitizers for dye-sensitized solar cells is ... -
A framework for significance analysis of gene expression data using dimension reduction methods
(Journal article; Peer reviewed, 2007)Background: The most popular methods for significance analysis on microarray data are well suited to find genes differentially expressed across predefined categories. However, identification of features that correlate ... -
A Monte Carlo Algorithm for Immiscible Two-Phase Flow in Porous Media
(Journal article; Peer reviewed, 2017)We present a Markov Chain Monte Carlo algorithm based on the Metropolis algorithm for simulation of the flow of two immiscible fluids in a porous medium under macroscopic steady-state conditions using a dynamical pore ... -
A novel compound isolated from Sclerochloa dura has anti-inflammatory effects
(Journal article; Peer reviewed, 2016)The activation of phospholipase A2 (PLA2) by means of pro-inflammatory cytokines results in the subsequent release of arachidonic acid (AA) and generates eicosanoids, which further propagate inflammation. Through cyclooxygenases ... -
A procedure to find thermodynamic equilibrium constants for CO2 and CH4 adsorption on activated carbon
(Journal article; Peer reviewed, 2015)Thermodynamic equilibrium for adsorption means that the chemical potential of gas and adsorbed phase are equal. A precise knowledge of the chemical potential is, however, often lacking, because the activity coefficient of ... -
A robust method to calculate the volume phase transition temperature (VPTT) for hydrogels and hybrids
(Journal article; Peer reviewed, 2017)Here, we report three different methods to determine the volume phase transition temperature (VPTT) of various systems including poly(N-isopropylacrylamide) (pNIPAm) based nanogels, Au nanoclusters and a combination of ... -
A sensitive and compact optical detector based on digital lock-in amplification
(Peer reviewed; Journal article, 2021)We report a sensitive, fixed-wavelength, lock-in-based optical detector built from a light-emitting diode, two colour filters, a photodetector, a small number of discrete analogue components, and a low-cost microcontroller ... -
A simple synthetic route to methyl 3-fluoropyridine-4-carboxylate by nucleophilic aromatic substitution
(Journal article; Peer reviewed, 2006)The nitro group of methyl 3-nitropyridine-4-carboxylate (1) has successfully been replaced by fluoride anion via nucleophilic aromatic substitution to give the 3-fluoropyridine- 4-carboxylate 2. -
A synthesis of atmospheric mercury depletion event chemistry in the atmosphere and snow
(Journal article; Peer reviewed, 2008)It was discovered in 1995 that, during the spring time, unexpectedly low concentrations of gaseous elemental mercury (GEM) occurred in the Arctic air. This was surprising for a pollutant known to have a long residence time ... -
A theoretical and experimental benchmark study of core-excited states in nitrogen
(Journal article; Peer reviewed, 2018)The high resolution near edge X-ray absorption fine structure spectrum of nitrogen displays the vibrational structure of the core-excited states. This makes nitrogen well suited for assessing the accuracy of different ... -
Accelerated hydrolysis method for producing partially degraded polyester microplastic fiber reference materials
(Peer reviewed; Journal article, 2020)Microplastic fibers (MPFs) from textiles significantly contribute to the microplastic (MP) load in many environmental matrices and have been shown to negatively impact the organisms therein. Most fate and effect studies ... -
Acetonitrile as a Building Block and Reactant
(Journal article; Peer reviewed, 2018)Acetonitrile is popular as a solvent for performing organic reactions, as a ligand in inorganic chemistry, as a mobile phase in chromatography, and as an electrolyte solvent in dye-sensitized solar cells. This is mainly ... -
Activation of multiple stress responses in Staphylococcus aureus substantially lowers the minimal inhibitory concentration when combining two novel antibiotic drug candidates
(Peer reviewed; Journal article, 2023)The past few decades have been plagued by an increasing number of infections caused by antibiotic resistant bacteria. To mitigate the rise in untreatable infections, we need new antibiotics with novel targets and drug ... -

Adamantyl Side Chains as Anti-Aggregating Moieties in Dyes for Dye-Sensitized Solar Cells
(Peer reviewed; Journal article, 2022)Designing and evaluating novel dye concepts is crucial for the development of the field of dye-sensitized solar cells (DSSCs). In our recent report, the novel concept of tethering the anti-aggregation additive chenodeoxycholic ... -
Adaptation of central metabolite pools to variations in growth rate and cultivation conditions in Saccharomyces cerevisiae
(Peer reviewed; Journal article, 2021)Background Saccharomyces cerevisiae is a well-known popular model system for basic biological studies and serves as a host organism for the heterologous production of commercially interesting small molecules and proteins. ... -
Adsorption of an Ideal Gas on a Small Spherical Adsorbent
(Peer reviewed; Journal article, 2021)The ideal gas model is an important and useful model in classical thermodynamics. This remains so for small systems. Molecules in a gas can be adsorbed on the surface of a sphere. Both the free gas molecules and the adsorbed ... -
