The self-assembled monolayers (SAMs) derived from thionicotinamide (TNA), thioisonicotinamide (iTNA), and 5-(4-pyridyl)-1,3,4-oxadiazole-2-thiol (Hpyt) on gold have been characterized via surface-enhanced Raman scattering (SERS) as a function of pH and applied potential. Density functional theory calculations performe…
Structural analysis methodology relating to the dynamic analysis of ship structures is presented. The focus is on numerical analysis procedures, using the finite element method. The equations of motion are defined, and the corresponding solution methods described. Finite element modelling considerations for various le…
Abstract Der steigende Energiebedarf und der damit verbundene CO2‐Ausstoß bei gleichzeitig abnehmenden Reserven an fossilen Rohstoffen erfordert neue Konzepte zur nachhaltigen Energieerzeugung. Das sogenannte Adam‐und‐Eva‐Prinzip zur CO2‐freien Gewinnung von Methanol aus Kohle und durch Nuklearenergie wird aufgegriffe…
A combination of electron- and ion-beam lithographies has been applied to fabricate patterns of plasmonic nanoparticles having tailored optical functions: they create hot-spots at predefined locations on the nanoparticle at specific wavelengths and polarizations of the incident light field. Direct inscribing of comple…
The title compound, betaine 0.77-perhydrate 0.23-hydrate, (CH3)3N(+)CH2COO(-)·0.77H2O2·0.23H2O, crystallizes in the orthorhombic noncentrosymmetric space group Pca2(1). Chiral molecules of hydrogen peroxide are positionally disordered with water molecules in a ratio of 0.77:0.23. Betaine, 2-(trimethylazaniumyl)acetate…
The phase diagram of carbon is mapped to high pressure using a computationally-tractable potential model. The use of a relatively simple (Tersoff-II) potential model allows a large range of phase space to be explored. The coexistence (melting) curve for the diamond crystal/liquid dyad is mapped directly by modelling t…
We observed the delayed electron detachment induced by multiphoton absorption of hot, zinc phthalocyanine negative ions (C${}_{32}$H${}_{16}$N${}_{8}$Zn${}^{\ensuremath{-}}$) stored in an electrostatic ion storage ring. To examine the critical parameters and conditions that characterize the delayed processes, we perfo…
Novel UV‐photopolymerizable siloxane‐modified methacrylate/Boehmite nanocomposites were experimented as possible protective coatings for different substrates. To this aim, unfilled and Boehmite‐filled suspensions were applied and photocured on a glass substrate. A subsequent detailed experimental characterization was…
The effect of alkali content (% K2O + %Na2O) on the mechanical properties of alkali activated blast furnace paste has been investigated. The paper presents the study on workability, compressive strength, split tensile strength and microstructure of alkali activated blast furnace slag paste specimens prepared by using…
Most nucleoside diphosphate kinases (NDPKs) are hexamers. The C-terminal tail interacting with the neighboring subunits is crucial for hexamer stability. In the NDPK from Mycobacterium tuberculosis (Mt) this tail is missing. The quaternary structure of Mt-NDPK is essential for full enzymatic activity and for protein s…
Amine scrubbing is usually considered as the most efficient technology for CO2 mitigation through postcombustion Carbon Capture and Storage (CCS). However, optimization of the amine structure to improve the solvent properties requires to sample a large number of possible candidates and hence to gather a large amount o…
Air-stable reactive metal nanopowders (RMNPs) of group 4 transition metals and aluminum were produced via a sonochemically agitated reaction of MCl 4 (M = Ti, Zr, Hf) with 4 equiv of lithium aluminum hydride (LiAlH 4, LAH) under an atmosphere of N 2 in Et 2 O, generating in situ the tetrahydroaluminate of the respecti…
Competitive cross-/homo-photocyclodimerization of anthracene (AN) and 2-anthracenecarboxylic acid (AC) mediated by a chiral hydrogen-bonding template (TKS) was investigated under various conditions. The cross-photocyclodimerization was favored by a factor of 4-5 at all temperatures and wavelengths examined to afford t…
The aim of this study was to investigate the ability of nano-sized collagen I molecules (nanoparticles or nanofibrils) and a 5-azacytidine (5-aza) treatment to enhance the differentiation of rat mesenchymal stem cells (MSCs) toward a cardiomyogenic phenotype in vitro. Second passaged MSCs were cocultured with nano-siz…
A gliding arc is a plasma that can be operated at atmospheric pressure and applied for plasma surface treatment for adhesion improvement. In the present work, glass-fibre-reinforced polyester plates were treated using an atmospheric pressure gliding arc discharge with an air flow to improve adhesion with a vinylester…
An equivalent circuit model was developed for polymer solar cells (PSCs), which explains correctly their behavior under different test conditions. We examine here the validity of that model for degraded PSCs. For that purpose, investigations were carried out on solar cells based on the interpenetrating bulk heterojunc…
Lumineszierende ZnO@Polymer-Kern/Schale-Nanopartikel wurden aufgebaut und für die Behandlung menschlicher Gehirntumor-Zellen mit Doxorubicin (DOX) beladen. Konfokale Laserscanmikroskopie zeigte, dass die ZnO@Polymer-DOX-Nanokomposite an Lysosomen zerfallen und dabei DOX-Moleküle freisetzen, die anschließend in den Zel…
Abstract Diesel oil was used as adsorbate, while corn stalk, wheat straw and sawdust were used as natural sorbents for adsorbing and absorbing pure oil and oil in water. The results showed that all three agricultural wastes absorbed diesel. The corresponding saturated sorption amounts of wheat straw, corn stalk and sa…
Abstract Perforating wells calls for careful planning to maximize well productivity over the life of the well, and to prevent time and money losses due to unexpected side effects. A large class of wells and in particular high-pressure wells are susceptible to gunshock damage when they are perforated with inappropriate…
Ma bamboo (Dendrocalamus latiflorus Munro) is the most distributed bamboo species in Taiwan, and its newly grown biomass within one growing season is the highest compared to the other local bamboo species. However, little is known about the cell wall chemical composition variations and distributions in Ma bamboo durin…
