How many solvent molecules and in what way do they interact directly with biomolecules? This is one of the most challenging questions regarding a deep understanding of biomolecular functionalism and solvation. We herein present a novel NMR spectroscopic study,...
Control the Wettability of Poly(N-isopropylacrylamide-co-1-adamantan-1-ylmethyl acrylate) Modified Surfaces: The More Ada, the Bigger Impact?
Surface-initiated SET-LRP was used to synthesize polymer brush containing N-isopropylacrylamide and adamantyl acrylate using Cu(I)Cl/Me6-TREN as precursor catalyst and isopropanol/H2O as solvent. Different reaction conditions were explored to investigate the influence...
Water Mediated Proton Hopping Empowers Proteins
Quantum dynamics simulations are used to test and validate the hypothesis that enhanced electronic activity and energetic efficiency in hydrated proteins are due to water-mediated proton hopping between peptide and peptenol states. Water is thereby an integral part of...
Monte Carlo Simulation of Carbon Monoxide, Carbon Dioxide and Methane Adsorption on Activated Carbon
In this study, the adsorption capacity of pure and activated carbon with regard to carbon monoxide (CO), carbon dioxide (CO2) and methane (CH4) gases at 298 K and pressure from 0.01 up to 2.0 MPa has been investigated computationally. Computational work refers to...
Thermodynamics of Pharmaceuticals: Prediction of Solubility in Pure and Mixed Solvents with PC-SAFT
A new scheme is presented for the parameterization of pharmaceuticals in the context of the perturbed-chain statistical associating fluid theory (PC-SAFT). The pharmaceutical parameters are fitted to experimental solubility values in three different solvents, i.e., a...
Adsorption of N2, CH4, CO and CO2 Gases in Single Walled Carbon Nanotubes: A Combined Experimental and Monte Carlo Molecular Simulation Study
In this study, the adsorption capacity of single-wall carbon nanotubes (SWCNTs) bundles with regard to the pure CH4, N2, CO and CO2 gases at 298K and pressure range from 0.01 up to 2.0MPa has been investigated experimentally and computationally. Experimental work...
Predicting Fluid Phase Equilibrium via Histogram Reweighting with Gibbs Ensemble Monte Carlo Simulations
One of the most challenging areas to which molecular simulation has contributed significantly over the last decades is without a doubt the accurate and efficient prediction of fluid phase equilibria. In this work we combine two of the most powerful methods that have...
Influences on the Stability of Collagen Triple-Helix
Collagen forms a triple helix structure which consists of three tightly coiled polyproline II-type (PPII) strands with the repeating amino acid motif Xaa-Yaa-Gly, where Xaa and Yaa are often proline (Pro) and hydroxproline (Hyp), respectively. The thermal and...
Molecular Modeling and Simulation of Raney Nickel
Raney Nickel is a nanostructured catalyst which is used in a variety of industrial processes. It has a characteristic porous, amorphous structure. Since the structure of both the precursor alloy and the active form of Raney Nickel is determining the catalytic activity...
Elucidation of the Biding Mechanism of Renin using a Wide Array of Computational Techniques and Biological Assays
We investigate the binding mechanism in renin complexes, involving three drugs (remikiren, zankiren and enalkiren) and one lead compound, which was selected after screening the ZINC database. For this purpose, we used ab initio methods (the effective fragment...
