Wood plastic composites have gained relevance in recent years as an alternative to wood boards. However, because the cavities in wood fibres are compressed by high processing pressure during the extrusion of wood plastic composites, the product densities show a range of up to 1.5 g/cm3depending on wood content and bas…
It is generally accepted that the exposed surfaces of silicon crystals are highly reactive due to the dangling bonds which protrude into the vacuum. However, surface reconstruction not only modifies the reactivity of bulk silicon crystals, but also plays a key role in determining the properties of silicon nanocrystals…
High-k barium strontium titanate (BST) thin films were deposited onto glass substrates to demonstrate integrated capacitors for power supply in high-speed digital packages. Ferroelectric BST films were sputter deposited onto solution-derived lanthanum nickel oxide (LNO) electrodes. Zirconium oxide was studied for the…
Glycoproteins adsorbing on an implant upon contact with body fluids can affect the biological response in vitro and in vivo, depending on the type and conformation of the adsorbed biomacromolecules. However, this process is poorly characterized and so far not controllable. Here, protein monolayers of high molecular co…
Abstract Aqua‐coordinated sandwich‐type polyoxometalates (POMs), {[WZnTM2(H2O)2](ZnW9O34)2}n− (TM=RhIII, PdII, and PtII), catalyze olefin epoxidation with hydrogen peroxide and have been well established, and they present an advance toward the utilization of olefins. To elucidate the epoxidation mechanism, we systemat…
Highly selective detection of intracellular glutamine (Gln) is very essential to understand the roles of Gln in some biological processes. Here, we report a new fluorescent method for selective imaging of Gln in live cells with an aldehyde-containing iridium complex, [Ir(pba) 2 (DMSO) 2 ]PF 6 (Hpba = 4-(2-pyridiyl)ben…
Wide-line 1H NMR intensity and differential scanning calorimetry measurements were carried out on the intrinsically disordered 73-residue full transactivation domain (TAD) of the p53 tumor suppressor protein and two peptides: one a wild type p53 TAD peptide with a helix pre-structuring property, and a mutant peptide w…
U 3 O 8 is considered to be the most stable phase for uranium oxide. Its structural properties must be accurately understood to foresee and manage aspects such as its leaching behavior when spent nuclear fuel is stored in an oxidative environment. Moreover, as fuel irradiation causes the formation of fission products…
Abstract A combination study of magnetic and magnetostrictive properties in directionally cast (DC) (un‐annealed) and differently heat‐treated Fe–19 at% Ga samples was carried out at room temperature. Slow cooling leads to an increase in the occupation of [2 0 0] easy magnetic axis. However, structural ordering of Ga…
Cobalt-, zinc-, and nickel-zinc-substituted nano-size manganese ferrite powders, MnFe 2 O 4 , Mn 0.8 Co 0.2 Fe 2 O 4 , Mn 0.8 Zn 0.2 Fe 2 O 4 and Mn 0.8 Ni 0.1 Zn 0.1 Fe 2 O 4 , were fabricated using a sol-gel method, and their crystallographic and magnetic properties were subsequently studied. The MnFe 2 O 4 ferrite…
The application of alternative raw materials to manufacture particleboards has gained considerable attention and it is now the objective of various studies. The capim-annoni (Eragrostis plana Nees.) is an invasive grass in the southern fields of Brazil and appears to be an example of such materials. This study aimed t…
Co3O4 decorated flower-like g-C3N4 hybrid nanocatalysts were successfully synthesized and prepared via a facial hydrothermal method. The composition and morphology of the as-synthesized Co3O4/g-C3N4 nanocatalysts were characterized by the techniques of XRD, FT-IR, SEM, TEM, XPS and N2-sorption. The analysis results in…
We calculate the spectrum of the Andreev boundary modes in a two-dimensional superconductor formed at an interface between two different nonsuperconducting materials, e.g., insulating oxides. Inversion symmetry is absent in this system, and both the electron band structure and the superconducting pairing are strongly…
Pellet fluidized bed reactors have been widely used to soften water. Reports from laboratory-scale research on the particle growth kinetics of calcium carbonate in pellet reactors have been put forward. However, the reports have not been comprehensive as they only consider the influence of supersaturation on the calci…
One-dimensional (1D) nucleation is important in crystal growth, amyloid fibril formation, and supramolecular polymerization. The nucleation rate can be readily calculated, but there is no consensus on the critical length. In this work, we employ a splitting probability to derive an analytical expression for the critic…
Multiple-band electronic structure and proximity to antiferromagnetic (AF) instability are the key properties of iron-based superconductors. We explore the influence of scattering by the AF spin fluctuations on transport of multiple-band metals above the magnetic transition. A salient feature of scattering on the AF f…
ABSTRACT Nanocomposites of polyetheretherketone (PEEK) and hydroxyapatite (HA) nanoparticles treated with a silane coupling agent were successfully prepared by twin screw extrusion and injection molding. Some of the samples were annealed after the injection molding. The silane treatment promoted an improvement of the…
Super-high pressure (SHP) technique plays an increasing role in the fields of materials science and engineering. Herein, the Mg 97 Zn 1 Y 2 alloy was heat-treated under SHP (6 GPa) by cubic-anvil large-volume press with six rams for 2 h in the temperature range of 500–1200 °C. The microstructure and mechanical propert…
Nano sized CoxNi1‐xFe2O4(0≤x≤1) samples were prepared by solution combustion method using glycine as fuel, maintaining a fuel to oxidizer ratio of 0.8. PXRD and FTIR analysis confirms the formation of the spinel phase. Non spherical and highly crystalline nature of the sample was revealed by HRTEM analysis. Lattice pa…
Abstract In this paper, we use a molecular dynamics simulation and Raman scattering measurements to study the vibrational and structural characteristics of barium disilicate, BaSi 2 O 5 , in vitreous and crystalline states. Our proposed atomic interaction potential describes the structural and dynamic behaviour of thi…
