Abstract Polyethylene samples were surface fluorinated using a F 2 /N 2 mixture under 0.1 MPa at 35, 70 or 95 °C for different times. Space charge accumulation was found to show four basic types for each fluorination temperature with increasing fluorination time. But the fluorination times needed for the formation of…

Abstract Vanadium dioxide (VO 2 ) films were prepared by the sol–gel method on high-purity silicon substrates, in which cetyltrimethyl ammonium bromide (CTAB) was used as a functional additive to form nano-porous structure in the VO 2 films. The morphology, crystalline structure and stoichiometry of the films were inv…

The coupling of plasmonic resonances with the multiple phonon modes of a plasmonic supracrystal is studied. Ultrafast optical pump-probe spectroscopy with variable wavelength allows the selective detection of the breathing mode, the interparticle vibrations, and the vibration of the whole structure. Thanks to this sel…

One of the fundamental problems in supramolecular chemistry, as well as in material sciences, is how to control the self-assembly of polymers on the nanometer scale and how to spontaneously organize them towards the macroscopic scale. To overcome this problem, inspired by the self-assembly systems in nature, which fea…

A solid-state polymerizable monomer, 2,5-dibromo-3,4-propylenedioxythiophene (DBProDOT), was synthesized at 25 °C to produce a conducting polymer, poly(3,4-propylenedioxythiophene) (PProDOT). Crystallographic studies revealed a short interplane distance between DBProDOT molecules, which was responsible for polymerizat…

The spin thermoelectric properties of a zigzag edged ferromagnetic (FM) graphene nanoribbon are studied theoretically by using the non-equilibrium Green's function method combined with the Landauer-Büttiker formula. By applying a temperature gradient along the ribbon, under closed boundary conditions, there is a spin…

Abstract The interest in applications of atmospheric‐pressure plasmas to solve surface‐technological tasks was originally motivated primarily by the expectation that major cost savings could be achieved if plasma‐based processes, conventionally run below 1 mbar, could now be performed at ambient pressure. However, it…

Organic field-effect transistors (OFETs) have attracted attention in the field of organic electronics. The conducting channel of OFETs is highly sensitive to out stimulus, so OFETs can be used as ultrasensitive sensors and actuators. Here, a new kind of OFET containing micro- and nanocrystals of a pentacene analogue i…

A novel fluorescence assay system for glucose was developed with thioglycollic acid (TGA)-capped CdTe quantum dots (QDs) as probes. The luminescence quantum yield of the TGA-capped CdTe QDs was highly sensitive to H2 O2 and pH. In the presence of glucose oxidase, glucose is oxidized to yield, gluconic acid and H2 O2 .…

We report on unusual lattice parameter changes and tunable magnetic moment compensation in Mn50−xCo25Ga25+x (x = 0-25) Heusler alloys by substituting Ga for Mn. The observed lattice parameter first increases with increasing Ga content x, showing a maximum at x = 12.5, and then abnormally decreases due to the enhanced…
