Three is a magic number: Antibodies adsorbed on bare graphene lose their ability to recognize antigens. However, this obstacle can be overcome by the conjugation of these antibodies to self-assembled monolayers of a tripodal compound (see picture).
The structural and morphological studies of a number of tungsten (W) thin films were carried out using grazing incidence x-ray diffraction, x-ray reflectivity and grazing incidence small-angle x-ray scattering. The W films were prepared by magnetron sputtering in an Ar atmosphere at various pressures and with differen…
The dynamics of charge separation in aqueous suspensions of regioregular P3HT nanoparticles containing PCBM were investigated for the first time using femtosecond transient absorption spectroscopy. This investigation is supported by the recently reported use of regioregular P3HT/PCBM nanoparticles as charge trapping a…
Pyrochemical reprocessing involves the use of molten LiCl-KCl (lithium chloride-potassium chloride) eutectic salt at 773 K for the recovery of uranium and plutonium from spent metallic fuel of fast breeder reactors. The materials selected for such corrosive environments should withstand high temperatures and at the sa…
Five different Hall Effect sensors were modeled and their performance evaluated using a three dimensional simulator. The physical structure of the implemented sensors reproduces a certain technological fabrication process. Hall voltage, absolute, current-related, voltage-related and power-related sensitivities were ob…
Enhancing the durability of fuel cells for the transportation sector requires a better understanding of the fundamental processes that cause degradation. Field-operated PEMFCs have been shown to develop a thin parallel band of Pt inside the membrane. Reports on the effect of the Pt band on membrane durability are cont…
Abstract In the present study we have selected three different condensation reactions as model reactions, namely the hydroxylalkylation of anisole by paraformaldehyde to bis(methoxyphenyl)methane, the Pechmann condensation of phenols with ethyl acetoacetate (EAA) to coumarins and the Knoevenagel condensation of two al…
A number of well-known type II inhibitors (ATP-noncompetitive) that bind kinases in their DFG-out conformation were tested against wild-type LRRK2 and the most common Parkinson's disease-linked mutation, G2019S. We found that traditional type II inhibitors exhibit surprising variability in their inhibition mechanism b…
In this review article, we present recent studies of peculiar Rashba spin-split energy band structures appearing at surfaces of metallic and semiconducting substances as well as surfaces of topological insulators utilizing state-of-the-art spin- and angle-resolved photoemission spectroscopy. It is shown in this articl…
Comprehensive understanding of thermodynamic properties of metallic nanoparticles is of significance for their utility in catalysis. In this article, we have employed molecular dynamics simulations with quantum Sutton–Chen many-body potentials to examine the thermal stability of Au–Pt core–shell nanoparticles with dif…
A series of new donor–acceptor π-conjugated copolymers incorporating 5,10-dihydroindolo[3,2- b ]indole (DINI) as an electron donating unit have been designed, synthesized, and explored in bulk heterojunction solar cells with diketopyrrolopyrrole and thienopyrroledione as the electron accepting units. A significant eff…
Interpenetrating network (IPN) hydrogels were recently introduced to the cartilage tissue engineering literature, with the approach of encapsulating cells in thermally gelling agarose that is then soaked in a poly(ethylene glycol) diacrylate (PEGDA) solution, which is then photopolymerized. These IPNs possess signific…
Plasmonic nanostructures confine light on the nanoscale, enabling ultra-compact optical devices that exhibit strong light–matter interactions. Quantum dots are ideal for probing plasmonic devices because of their nanoscopic size and desirable emission properties. However, probing with single quantum dots has remained…
Trivalent cobalt complexes of salicylaldimine in the presence of an inter- or intramolecular nucleophilic cocatalyst have proven to be excellent catalysts for the copolymerization of CO 2 and epoxides to selectively afford the corresponding polycarbonates in perfectly alternating nature. Especially, bifunctional cobal…
N-Linked glycosylation is an essential post-translational protein modification in the eukaryotic cell. The initial transfer of an oligosaccharide from a lipid carrier onto asparagine residues within a consensus sequon is catalyzed by oligosaccharyltransferase (OST). The first X-ray structure of a complete bacterial OS…
Abstract The blood-brain barrier (BBB), which protects the central nervous system (CNS) from unnecessary substances, is a challenging obstacle in the treatment of CNS disease. Many therapeutic agents such as hydrophilic and macromolecular drugs cannot overcome the BBB. One promising solution is the employment of polym…
This paper is concerned with the numerical solution of an inverse diffraction grating problem, which is to reconstruct a periodic grating profile from measurements of the phaseless diffracted field at a constant height above the grating structure. An efficient continuation method is developed to recover the Fourier co…
AIM: This study examines the absolute quantification of particle uptake into cells. METHODS: We developed a novel method to analyze stacks of confocal fluorescence images of single cells interacting with nano-and micro-particles. Particle_in_Cell-3D is a freely available ImageJ macro. During the image analysis routine…
Introduction of a naphthalocyanine moiety to phthalocyanine allows for a gradual red shift of the absorption spectrum in the resulting chromophore. Using silicon as a core atom allows for the introduction of additional siloxane side chains which mitigate dye aggregation. A dye-sensitized solar cell with this hybrid se…
Structural, chemical and electronic properties of electroforming in the TiN/HfO(2) system are investigated at the nanometre scale. Reversible resistive switching is achieved by biasing the metal oxide using conductive atomic force microscopy. An original method is implemented to localize and investigate the conductive…
