The aim of this work was to examine the influence the lignin component of wood on the photodegradation of high-density polyethylene (HDPE) in wood/HDPE (WPE) composites. The neat HDPE and wood/HDPE composites were prepared using a twin screw extruder followed by an injection moulder. The lignin content was varied from…
The electrons in undoped graphene behave as massless Dirac fermions. Therefore, graphene can serve as a unique condensed-matter laboratory for the study of various relativistic effects, including quantum electrodynamics (QED) phenomena. Although theoretical models describing electronic properties of graphene have been…
In the past three decades, the use of polymeric materials has increased dramatically for biomedical applications. Many α-amino acids derived biodegradable polymers have also been intensely developed with the main goal to obtain bio-mimicking functional biomaterials. Polymers derived from α-amino acids may offer many a…
Surface faceting on sidewalls is ubiquitously observed during crystal growth of semiconductor nanowires. However, predicting the thermal transport characteristics of faceted nanowires relevant to thermoelectric applications remains challenging. Here, direct molecular dynamics simulations show that thermal conductivity…
The effect of solvent permittivity on the fibre morphology of PCL electrospun membranes for tissue engineering applications is studied. Morphological results indicate that polar solvents with higher permittivity are able to promote the formation of sub-micrometric fibres, while apolar solvents yield microfibres with a…
Mit Diarylbibenzofuranon-Einheiten quervernetzte Polymere wurden durch Polyaddition synthetisiert. Der Bindungsaustausch der Gele und ihre makroskopische Selbstheilung wurden an Luft bei Raumtemperatur im Dunkeln erreicht. Die makroskopische Verbindung komplett getrennter Teile war erfolgreich (siehe Bild).
Abstract Textile fibers and yarns of high conductivity, and their integration into wearable textiles for different electronic applications, have become an important research field for many research groups throughout the world. We have produced novel electrically conductive textile yarns by vapor‐phase polymerization (…
Nanoscale complexes of recombinant silk molecules containing THPs with DNA are designed as less cytotoxic and highly target-specific gene carriers. Genetically engineered silk proteins containing poly(L-lysine) domains to interact with pDNA and the THP to bind to specific tumorigenic cells for target-specific pDNA del…
We demonstrated the fabrication of graphene nanoribbons (GNRs) as narrow as 35 nm created using scanning probe lithography to deposit a polymer mask(1-3) and then fluorinating the sample to isolate the masked graphene from the surrounding wide band gap fluorographene. The polymer protected the GNR from atmospheric ads…
A curious response of graphene to light and heat may be useful for optoelectronic applications.
Cluster formation and gelation are studied in a colloidal model system with competing short-range attractions and long-range repulsions. In contrast to predictions by equilibrium theory, the size of clusters spontaneously formed at low colloidal volume fractions decreases with increasing strength of the short-range at…
Supramolecular nanoparticles represent a key field in recent research as their synthesis through self-assembly is straightforward and they often can respond to external triggers. A fundamental understanding of structure-directing factors is highly desirable for a targeted structure design. This contribution demonstrat…
Click the CMPs and POPs: The Huisgen 1,3-dipolar cycloaddition reaction can be used to generate covalent porous organic materials such as conjugated microporous polymers (CMPs) and porous organic polymers (POPs). A triazole-linked network based on complementary tetrahedral monomers has been prepared by means of click…
The role of 5-fold twin boundary on the structural and mechanical properties of fcc Fe nanowire under tension is explored by classical molecular dynamics. Twin-stabilized fcc nanowire with various diameters (6-24 nm) are examined by tension tests at several temperatures ranging from 0.01 to 1100 K. Significant increas…
A simple and one-pot method for the synthesis of water-soluble, red-emitting, highly fluorescent gold nanoparticles has been reported using 11-mercaptoundecanoic acid (11-MUA) as the protecting group. We found that the fluorescent gold nanoparticles could selectively detect copper ions in aqueous solution, with a limi…
We prepared three types of non-Cu RHQ-Nb3Al wire samples with different matrix structures: an all-Ta matrix,a composite matrix of Nb and Ta with a Ta inter filament, and an all-Nb matrix. Neutron diffraction patterns of the wire samples were measured at room temperature in J-PARC "TAKUMI". To obtain residual strains o…
A double-stranded system, modeled by a Frenkel-Kontorova lattice, is studied through nonequilibrium molecular dynamics simulations. We have investigated the thermal conductance influenced by the intra-chain interaction as well as by the inter-chain interaction. It is found that the intra-chain interaction always enhan…
We present a study of the thermodynamic and physical properties of Ta5Si3 compounds by means of density functional theory based calculations. Among the three different structures (D8m, D8l, D88), the D8l structure (Cr5B3-prototype) is the low temperature phase with a high formation enthalpy of -449.20kJ/mol, the D8m s…
Here we reported on the synthesis and characterization of Co3O4 gillyflower-like nanostructures (termed as CGN) with peroxidase-like activity via an L-arginine-assisted hydrothermal synthesis approach. The CGN were characterized by a wide range of physicochemical characterization techniques. The temperature-dependence…
Abstract UHMWPE/MWCNT and UHMWPE/GNS composites with a segregated network are prepared. TEM and SEM images indicate that the conducting fillers are distributed on the UHMWPE surface and form a segregated conducting network. The percolation threshold of UHMWPE/GNS composites is ≈0.25 wt% and that of UHMWPE/MWCNT compos…
