High-quality thin films of conjugated molecules with smooth interfaces are important to assist the advent of organic electronics. Here, we report on the layer-by-layer growth of the organic semiconductor molecule p-sexiphenyl (6P) on the transparent electrode material graphene. Low energy electron microscopy and micro low energy electron diffraction reveal the morphological and structural evolu...

We describe the synthesis and characterisation of novel photocatalytic multiphase micro-droplet reactors comprising TiO2 nanosheets dispersed in poly(diallyldimethylammonium) chloride and adenosine 5'-triphosphate or poly(ethylene glycol) 4-nonylphenyl 3-sulfopropyl complex coacervates. We demonstrate significant variations in the degree of equilibrium partitioning of small molecule dyes into t...

Vibrational spectroscopy usually provides structural information averaged over many molecules. We report a larger peak position variation and reproducibly smaller FWHM of TERS spectra compared to SERS spectra indicating that the number of molecules excited in a TERS experiment is extremely low. Thus, orientational averaging effects are suppressed and micro ensembles are investigated. This is sh...

In this paper we discuss newly developed microfabrication methods for liquid crystal polymer (LCP). LCP is a thermoplastic polymer made of aligned molecule chains with crystal-like spatial regularity. It exhibits unique electrical, physical and chemical properties, making it suitable for certain MEMS applications. MEMS-compatible fabrication processes such as metallization, plasma bulk etching ...

The versatile NanoTrackerTM 2 system is designed for the optical trapping of dielectric particles and optically refractive objects. Sizes range from sub-micrometer polystyrene and silica particles (beads) to living cells with diameters of >10μm. After automated calibration of the trap-particle system, the precise and reliable measurement of piconewton forces is possible. Applications include si...

Membrane-associated immunoglobulin (M-Ig) was isolated from Daudi cells which had been radioiodinated using lactoperoxidase. This M-Ig was found to have a molecular size on SDS-PAGE of 330,000 daltons. The component protein chains (micro and K) have molecular sizes of 75,000 and 33,000 daltons, respectively. Further studies showed that [(3)H]galactose can be incorporated into K-chains, but that...

Introduction The flavodoxins are a group of small proteins found in micro-organisms and eukaryotic algae that function to transfer electrons at low redox potential between other redox proteins in reactions such as nitrogen fixation and the photosynthetic reduction of NADP’ [ 1-41. They contain a single molecule of FMN bound strongly but non-covalently to the protein. The flavin is reduced in tw...

because of its kinetic nature and computational advantages, the lattice boltzmann method (lbm) has been well accepted as a useful tool to simulate micro-scale flows. the slip boundary model plays a crucial role in the accuracy of solutions for micro-channel flow simulations. the most used slip boundary condition is the maxwell slip model. the results of maxwell slip model are affected by the ac...

in this study, polyaniline molecule (emeraldine base) is modeled as a molecular wire and the effects of the metal/molecule coupling strength and the molecule length on the current-voltage (i-v) characteristics are numerically investigated. using a tight-binding hamiltonian model, the methods based on non-equilibrium green’s function theory, landauer formalism and newns-anderson model, our calcu...
