In this paper, we present a fabrication process of graphene field effect transistors (GFETs) using natural oxidation of aluminum as dielectrics, which provide an alternative fabrication choice for future flexible electronics with the large scale and arbitrary substrates. The high-quality monolayer graphene is preserve…
In the present work, the carbides and inclusions in H13 steel with different magnesium contents were investigated with the scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), and were calculated by the ThermoCalc and FactSage softwares, respectively. The growth of the MgAl2O4 spinel and Al2O3 at…
Silver nanoparticles used in consumer products are likely to be released into municipal wastewater. Transformation reactions, most importantly sulfidation, lead to the formation of nanoscale silver sulfide (nano-Ag2S) particles. In wastewater treatment plants (WWTP), ozonation can enhance the effluent quality by elimi…
Abstract In order to provide a solid basis for the correlation of microstructure and hydrogen isotope retention in tungsten, reference samples with different microstructures were prepared from a single batch of polycrystalline tungsten by standardised polishing and heat treatment procedures. Representative samples wer…
Linear aliphatic polyesters have been investigated extensively over the last decades. However, the relation between the configuration of the ester groups in the main chain and the mechanical properties is only poorly understood. Therefore, in this work the influence of the composition of these polymers on the morpholo…
Degassing of water during the ascent of hydrous magma in a volcanic edifice produces dramatic changes in the magma density and viscosity. This can profoundly affect the dynamics of volcanic eruptions. The water exsolution history, in turn, is driven by the water solubility and solution mechanisms in the silicate melt.…
The detection of carbon monoxide in solution and air has been achieved using simple, inexpensive systems based on the vinyl complexes [M(CHCHR)Cl(CO)(BTD)(PPh3 )2 ] (R=aryl, BTD=2,1,3-benzothiadiazole). Depending on the nature of the vinyl group, chromogenic and fluorogenic responses signalled the presence of this od…
The phase transitions and ferroelectricity of LiNbO3 and LiTaO3 have been investigated theoretically from first principles. The phonon analyses and the molecular dynamics simulations revealed that the ferroelectric phase transition is not conventional displacive type but order-disorder type with strong correlation bet…
This study reports on the preparation of heterogeneous catalysts with two different pore sizes, the Fe3O4@nSiO2@MCM-41-MnP and Fe3O4@nSiO2@MCM-41(E)-MnP catalysts. Such systems ally the catalytic properties of metalloporphyrins (MeP) with the magnetic properties of magnetite nanoparticles (Fe3O4) in a mesoporous MCM-4…
The present study was conducted to determine the recyclability and biodegradability of bamboo fabric-reinforced poly(lactic) acid (BF-PLA) composites for sustainable packaging. BF-PLA composite was recycled through the granulation, extrusion, pelletization and injection processes. Subsequently, mechanical properties (…
Thermally oxidized nanodiamond (OND), amine-functionalized ND (AND) and untreated ND (UND) were added to epoxy/TETA at 1 wt % loading. The ND enhanced the dynamic storage modulus of epoxy while decreasing the glass transition temperature because of the increment of free volume in the vicinity of the ND surfaces. The N…
The angstrom- and nanometer-scale crystallization and long-range ordering behavior of polyhedral oligosilsesquioxane–poly(ε-caprolactone) (POSS–PCL) shape memory nanocomposites under thermomechanical shape memory cycles and uniaxial stretching were studied by simultaneous wide-angle and small-angle X-ray scattering (W…
The interaction between catalytic nanoparticles (NPs) and their supports, which are often amorphous oxides, has not been well characterized at the atomic level, although it is known that, in some cases, NP–support interactions dominate the catalytic activity of the system. Furthermore, there is a lack of understanding…
Fused silica subwavelength structures (SWSs) with an average period of ~100 nm were fabricated using an efficient approach based on one-step self-masking reactive ion etching. The subwavelength structures exhibited excellent broadband antireflection properties from the ultraviolet to near-infrared wavelength range. Th…
The toxicological effects of pristine and chemically modified carbon nano-onions (CNOs) on the development of the freshwater polyp Hydra vulgaris were investigated in order to elucidate the ecotoxicological effects of CNOs. Chemical modifications of the CNOs were accomplished by surface functionalization with benzoic…
A porous collagen-based hydrogel scaffold was prepared in the presence of iron oxide nanoparticles (NPs) and was characterized by means of infrared spectroscopy and scanning electron microscopy. The hybrid scaffold was then loaded with fluorescein sodium salt as a model compound. The release of the hydrosoluble specie…
Layered double hydroxides (LDHs) are versatile materials used for intercalating bioactive molecules in the fields of pharmaceuticals, nutraceuticals and cosmetics, with the purpose of protecting them from degradation, enhancing their water solubility to increase bioavailability and improving their pharmacokinetic prop…
Toward the development of visible-light-driven molecular rotary motors, an overcrowded alkene-based ligand and the corresponding ruthenium(II) complex is presented. In our design, a 4,5-diazafluorenyl coordination motif is directly integrated into the motor function. The photochemical and thermal isomerization behavio…
Scaffolds for cardiac patch application must meet stringent requirements such as biocompatibility, biodegradability, and facilitate vascularization in the engineered tissue. Here, a bioactive, biocompatible, and biodegradable electrospun scaffold of poly(glycerol sebacate)-poly(ε-caprolactone) (PGS-PCL) is proposed as…
The first bioinspired hybrid white-light-emitting diodes (bio-HLEDs) featuring protein cascade coatings are presented. For easy fabrication a new strategy to stabilize proteins in rubber-like material was developed. The synergy between the excellent features of fluorescent proteins and the easily processed rubber prod…
