Catalysis is one of the most important technical and scientific developments, on which present-day society is based. For example, it is crucial to the production of fertilizers or clean fuels and needed for the abatement of exhaust gases. Frequently, the employed catalysts are being discovered in a very empirical way;…
The films formed by tetradecylamine (TDA) at the water-dodecane interface in the presence of hydrogen phosphate ions have been studied. Between pH 5 and 8, tetradecylammonium cations bind to hydrogen phosphate anions to form needle-shaped crystallites of tetradecylammonium hydrogen phosphate (TAHP). Fourier Transform…
Biosensors have proven to be a powerful tool for detecting diverse targets, such as proteins, DNA, and small molecules representing disease biomarkers, toxins, drugs and their metabolites, environmental pollutants, agrichemicals, and antibiotics with high sensitivity and specificity. The major objective of the researc…
ABSTRACT Specialized to simulate proteins in molecular dynamics (MD) simulations with explicit solvation, FF12MC is a combination of a new protein simulation protocol employing uniformly reduced atomic masses by tenfold and a revised AMBER forcefield FF99 with ( i ) shortened CH bonds, ( ii ) removal of torsions invol…
In this work we present a fully atomistic reactive (ReaxFF force field) molecular dynamics study of the structural and dynamical aspects of the one-side hydrogenation of graphene membranes, leading to the formation of the so-called graphone structure. We have considered different substrates: graphene, few-layers graph…
Abstract Beij.e.rinck'i.a. N.L. fem. n. Beijerinckia named after M.W. Beijerinck, the Dutch microbiologist (1851–1931). Straight or slightly curved rods, ∼0.5–2.0 × 1.6–4.5 μm , with rounded ends. Cells occur singly or appear as dividing pairs. Sometimes large, misshapen cells 3.0 × 5.0–6.0 µm occur; these are occasio…
Aufgrund der großen Bedeutung technischer Gummiwerkstoffe in industriellen Anwendungen ist die Vorhersage des Materialverhaltens ein aktuelles Forschungsgebiet. Insbesondere die Veränderung der Eigenschaften, die durch chemische Prozesse herbeigeführt werden, spielen eine große Rolle, da aufgrund gestiegener Anforderu…
In a structural analysis of the proteasome activator PafE in Mycobacterium tuberculosis, the binding of the activator or shorter constructs to the 20S proteasome core particle (20S CP) or derivatives was measured by isothermal titration calorimetry (Bai et al. Proc Natl Acad Sci USA 113: E1983-E1992. 2016). The data w…
Lead halide perovskites such as methylammonium lead triiodide (MAPI) have outstanding optical and electronic properties for photovoltaic applications, yet a full understanding of how this solution processable material works so well is currently missing. Previous research has revealed that MAPI possesses multiple forms…
Calcium/calmodulin-dependent kinase kinase 2 (CaMKK2) has been implicated in a range of conditions and pathologies from prostate to hepatic cancer. Here, we describe the expression in Escherichia coli and the purification protocol for the following constructs: full-length CaMKK2 in complex with CaM, CaMKK2 'apo', CaMK…
The crystal growth conditions of compounds of the series Srn+1IrnO3n+1 (n=1, 2 and ∞) are investigated. It was found that the ratio of IrO2:SrCO3 in the starting mixture is the most important variable in determining the phase formed. Good quality samples of Sr3Ir2O7 were found to have a sharp change in gradient at the…
This article presents a comprehensive review of the Hydrodynamic Scaling Model for the dynamics of polymers in dilute and nondilute solutions. The Hydrodynamic Scaling Model differs from some other treatments of non-dilute polymer solutions in that it takes polymer dynamics up to high concentrations to be dominated by…
In recent years, scientists have created artificial microscopic and nanoscopic self-propelling particles, often referred to as nano- or micro-swimmers, capable of mimicking biological locomotion and taxis. This active diffusion enables the engineering of complex operations that so far have not been possible at the mic…
Continuous monitoring of oxygen concentration is of great importance in many different areas of research which range from medical applications to food packaging. In the last three decades, significant progress has been made in the field of optical sensing technology and this review will highlight the one inherent to t…

We consider the high centrifugal compressor as the deformable hydro system. The main problem in creating such compressors is very high static and dynamic loads on the structural elements. The cause of stress are: high density of the gas, the small size of the flow channels, high-speed rotary, flexible shaft, the defor…
Atomistic details of the interaction of impurities with quasi-one-dimensional charge density wave (CDW) are revealed by scanning tunneling microscopy. Oxygen and pentacene adsorbates are utilized as strongly and weakly interacting impurities, respectively, on the well-known CDW state of the In atomic wire array on the…
Abstract Ethylene hydrogenation was investigated on size‐selected Pt13 clusters supported on three amorphous silica (a‐SiO2) thin films with different stoichiometries. Activity measurements of the reaction at 300 K revealed that on a silicon‐rich and a stoichiometric film, Pt13 exhibits a similar activity to that of P…
