In this study, reduced graphene oxide/polyimide (r-GO/PI) composite films, which showed significant enhancement in their electrical conductivity, were successfully fabricated. GO was prepared from graphite using a modified Hummers method. The GO was used as a nanofiller material for the preparation of r-GO/PI composit…

The ultrafast quasiparticle dynamics of Fe 1+ y Se 1− x Te x single crystals were investigated by dual-color transient reflectivity measurements (Δ R / R ) from 4.3 to 290 K. The electron–phonon coupling strength λ (=0.16–0.01) and the temperature-dependent energy of longitudinal-acoustic phonons were, respectively, o…

A method is presented for determining the dynamic contact angle at the three-phase contact between a solid, a liquid, and a vapor under an applied force, using molecular simulation. The method is demonstrated using a Lennard-Jones fluid in contact with a cylindrical shell of the fcc Lennard-Jones solid. Advancing and…

Photoluminescence (PL) of ZnO thin films prepared on c-Al 2 O 3 substrates by pulsed laser deposition (PLD) are investigated. For all samples, roomtemperature (RT) spectra show a strong band-edge ultraviolet (UV) emission with a pronounced low-energy band tail. The origin of this UV emission is analyzed by the tempera…

We investigate the response to temperature of a well-known colloid-polymer mixture. At room temperature the gas-liquid critical value of the second virial coefficient of the effective pairwise colloid-colloid interaction for the Asakura-Oosawa model predicts the onset of gelation observed experimentally with remarkabl…

The extracellular polysaccharide production by marine diatoms is a significant route by which photosynthetically produced organic carbon enters the trophic web and may influence the physical environment in the sea as observed for example when massive aggregation events on basin scale occur. Many papers showed that the…

Using Monte Carlo simulations, individual Brownian particles have been investigated in a one-dimensional random energy landscape whose energy levels are selected from a Gaussian distribution. The standard deviation of the distribution determines the roughness of the noise-like potential and was varied in the simulatio…

Carbon nanotubes (CNTs) have exceptional mechanical, electrical, and thermal properties compared with those of commercialized high-performance fibers. For use in the form of fabrics that can maintain such properties, individual CNTs should be held together in fibers or made into yarns twisted out of the fibers. Typica…

If a binary colloidal mixture is oppositely driven by an external field, a transition towards a laned state occurs at sufficiently large drives, where particles driven alike form elongated structures ('lanes') characterized by a large correlation length ξ along the drive. Here we perform extensive Brownian dynamics co…

We report the effects of electron doping on the ground state of a diamagnetic semiconductor FeGa${}_{3}$ with a band gap of $0.5$ eV. By means of electrical resistivity, magnetization, and specific heat measurements we have found that gradual substitution of Ge for Ga in FeGa${}_{3\ensuremath{-}y}$Ge${}_{y}$ yields me…

We demonstrate for the Asakura-Oosawa model and an extension of this model that uses continuous rather than hard potentials, how wetting properties at walls can be easily controlled. By increasing the interaction range of the repulsive wall potential acting on the colloids (while keeping the polymer-wall interactions…
