Flax fibre was treated with low concentrations of alkali and used to prepare poly(furfuryl alcohol) (PFA)-based composites through in situ polymerization of furfuryl alcohol. The properties of low concentrations of alkali-treated flax fibre and flax fibre–reinforced composites were characterized for their structure an…
In over 100 years of quartz glass fabrication, the applications and the optical requirements for this type of optical material have significantly changed. Applications like spectroscopy, UV flash lamps, the Apollo missions as well as the growth in UV and IR applications have directed quartz glass development towards n…
An all-solid-state quantum-dot-based photon-to-current conversion device is demonstrated that selectively detects the generation of hot electrons. Photoexcitation of Mn 2+ -doped CdS quantum dots embedded in the device is followed by efficient picosecond energy transfer to Mn 2+ with a long-lived (millisecond) excited…
The reversible oxidation of coordinated phenolates into phenoxyl radicals results in a dramatic quenching (>95%) of the luminescence of the f metal ion.
Graphene is a versatile composite reinforcement candidate due to its strong mechanical, tunable electrical and optical properties, and chemical stability. However, one drawback is the weak interfacial bonding, which results in weak adhesion to substrates. This could be overcome by adding polymer layers to have stronge…
The influence of Nd addition on microstructure and corrosion behavior of LAZ832 alloy was investigated by immersion test, electrochemical experiments, scanning electron microscopy (SEM), and X‐ray photoelectron spectroscopy (XPS). The results indicate that Nd addition leads to the coarsening of grains and the improvem…
In order to improve the performance and fundamental understanding of conducting polymers, development of new nanotechnologies for engineering aggregated states and morphologies is one of the central focuses for conducting polymers.
Tribological mechanisms of diamond-like carbon (DLC) films in a sand-dust environment are commonly unclear due to the complicated three-body abrasion caused by sand particles. This study investigates the three-body abrasion of the DLC film via molecular dynamics simulations. The influence factors such as the load, vel…
We report the first fluorescent molecular self-assembly on graphene. The quenching of the fluorescence of the adsorbed dye by the adjacent graphene is hindered at the molecular scale based on a spacer approach, through a specifically designed dual-functionalized self-assembling building block. This 3D tecton presents…
Hydrogels of spatially controlled physicochemical properties are appealing platforms for tissue engineering and drug delivery. In this study, core-shell silk fibroin (SF) hydrogels of spatially controlled conformation were developed. The core-shell structure in the hydrogels was formed by means of soaking the preforme…
A new alternative methodology based on γ-radiolysis has been successfully used for the synthesis of nanostructured PEDOT/Ag composites.
Physical parameters and their correlation with optical band gap and refractive index for amorphous Ge20Te80-xSbx (x = 0, 2, 4, 6, 8, 10) lone-pair semiconductors were discussed. Using average coordination number (⟨r⟩), lone-pair electrons (L) were calculated and found to decrease with an increase in the Sb content. Ho…

The influence of magnetocrystalline anisotropy on the magnetocaloric effect (MCE) was studied on single crystals of Co2B and compared to measurements on polycrystalline samples. Large differences in adiabatic temperature change ΔTad and magnetic entropy change ΔSM were found along the different crystallographic direct…

This thermochromism is characterized by the conversion of a light yellow viscous liquid, at room temperature, to a reddish substance close to 80 °C. The reversibil…
This study demonstrates the fabrication and characterization of a flexible thermoelectric (TE) power generator composed of silicon nanowires (SiNWs) fabricated by top‐down method and discusses its strain‐dependence analysis. The Seebeck coefficients of the p‐ and n‐type SiNWs used to form a pn‐module are 156.4 and −14…
Flax fibers were modified with NaOH and NaClO2 under different conditions in order to clarify effects of hemicelluloses and lignin removal on the morphology and properties of flax fibers, but also to improve fiber quality. The quality of flax fibers was characterized in terms of chemical composition, fineness, whitene…
In ferroelectric tunnel junctions, the tunnel resistance depends on the polarization orientation of the ferroelectric tunnel barrier, giving rise to tunnel electroresistance. These devices are promising to be used as memristors in neuromorphic architectures and as non-volatile memory elements. For both applications, d…
A rapid route of synthesizing pristine Co 4 Sb 12 at relatively low temperature was previously developed. However, filling the voids using the same procedure is not successful. We develop a new route to fabricate In-filled cobalt skutterudites with InSb nanoinclusions In x Co 4 Sb 12 –(InSb) y via solid–vapor reaction…
