#### Mg-doped ZnO films prepared by chemical bath deposition

A simple, low-temperature route for the chemical bath deposition of Mg-doped ZnO films, based on low-cost, abundant and non-toxic materials was developed. The film growth mechanism, the resulting morphology and texture were investigated in detail by scanning electron microscopy and X-ray diffraction measurements. It was found that substantial film growth is only possible in a ...

#### High-velocity impact deformation and perforation of fibre metal laminates

The quasi-static flexural and impact performance, up to projectile impact velocities of about 270 m s−1, of fibre metal laminates (FMLs), which consist of relatively thin, alternately stacked, layers of an aluminium alloy and a thermoset glass fibre epoxy composite, have been investigated. The effects of varying (a) the yield strength, tensile strength and ductility of the ...

#### Tailoring of surface plasmon resonances in TiN/(Al0.72Sc0.28)N multilayers by dielectric layer thickness variation

Alternative designs of plasmonic metamaterials for applications in solar energy-harvesting devices are necessary due to pure noble metal-based nanostructures’ incompatibility with CMOS technology, limited thermal and chemical stability, and high losses in the visible spectrum. In the present study, we demonstrate the design of a material based on a multilayer architecture with ...

#### A new insight into in vitro behaviour of poly(ε-caprolactone)/bioactive glass composites in biologically related fluids

In the present work, the role of content, size and chemical composition of gel-derived bioactive glass particles from the SiO2–CaO–P2O5 system in modulating the in vitro bioactivity, osteoinductive properties and long-term (up to 15 months) degradation behaviour of poly(ε-caprolactone)-based composite films was investigated. Bioactivity was assessed in simulated body fluid (SBF) ...

#### Probing polydopamine adhesion to protein and polymer films: microscopic and spectroscopic evaluation

Polydopamine has been found to be a biocompatible polymer capable of supporting cell growth and attachment, and to have antibacterial and antifouling properties. Together with its ease of manufacture and application, it ought to make an ideal biomaterial and function well as a coating for implants. In this paper, atomic force microscope was used to measure the adhesive forces ...

#### Enhanced dielectric properties of polyethylene/hexagonal boron nitride nanocomposites

A range of nanocomposites based on a polyethylene polymer and hexagonal boron nitride (hBN) filler have been explored in this study. The dielectric properties of the nanocomposites, which consisted of 2, 5, 10, 20 and 30 wt% of hBN, have been compared to the dielectric properties of the unfilled polyethylene blend. Scanning electron microscopy revealed that the hBN was uniformly ...

#### Conditions for the occurrence of acicular ferrite transformation in HSLA steels

For the class of steels collectively known as high strength low alloy (HSLA), an acicular ferrite (AF) microstructure produces an excellent combination of strength and toughness. The conditions for the occurrence of the AF transformation are, however, still unclear, especially the effects of austenite deformation and continuous cooling. In this research, a commercial HSLA steel was ...

#### Kinetics of vacancy annealing upon time-linear heating applied to dilatometry

A kinetic model for the diffusion-controlled annealing of excess vacancies under the experimentally relevant, non-isothermal condition of time-linear heating is presented and applied to dilatometry. The evolution of the vacancy concentration with time is quantitatively analyzed, considering as ideal sinks either dislocations or grain boundaries of spherical- or cylindrical-shaped ...

#### Evolution of glassy carbon under heat treatment: correlation structure–mechanical properties

In order to accommodate an increasing demand for glassy carbon products with tailored characteristics, one has to understand the origin of their structure-related properties. In this work, through the use of high-resolution transmission electron microscopy, Raman spectroscopy, and electron energy loss spectroscopy it has been demonstrated that the structure of glassy carbon at ...

#### New composite gyrotropic double-negative metamaterial

This work is the continuation of our study started in Tralle et al. (J Appl Phys 115:233509, 2014). In it, we examined the possibility of fabricating the metamaterial in a relatively simple way. Our idea was to use the three-component mixture of ingredients, where one of them is responsible for the negative permeability $\mu (\omega )$ of hypothetical metamaterial, while the ...

#### Bi3TeBO9: electronic structure, optical properties and photoinduced phenomena

Improvement of the nonlinear optical properties, mainly photoinduced enhancement of effective second harmonic generation was observed in Bi3TeBO9 (BTBO) crystals under irradiation of two external UV laser beams. The effect is caused by an interaction of two coherent photoinducing beams of nitrogen laser with wavelength 371 nm near the Bi3TeBO9 fundamental edge, resulting in ...

#### Factors affecting the hygroexpansion of paper

Paper is a widely used packaging material and is nowadays regaining importance, e.g., as bio-based and biodegradable material. Moreover, new technologies such as polymer–fiber composites, printed electronics and the deep drawing of paper are developing. The process stability and also the resulting quality of paper converting processes such as coating, metallization, printing, and ...

#### Poly(ε-caprolactone)-based membranes with tunable physicochemical, bioactive and osteoinductive properties

In contrast to currently used materials, membranes for the treatment of bone defects should actively promote regeneration of bone tissue beyond their physical barrier function. What is more, both material properties and biological features of membranes should be easily adaptable to meet the needs of particular therapeutic applications. Therefore, the role of preparation methods ...

#### A self-organising biomimetic collagen/nano-hydroxyapatite-glycosaminoglycan scaffold for spinal fusion

The use of spinal fusion surgery as a treatment for degenerative spinal conditions and chronic back pain is increasing. However, this technique requires use of a bone grafting material to fuse the vertebrae, traditionally autologous bone, which consists of an optimal combination of osteogenic cell precursors, extracellular matrix proteins and mineral components. To date, this ...

#### Modelling of microstructural evolution in multi-layered overlay coatings

Functionally graded, multi-layered coatings are designed to provide corrosion protection over a range of operating conditions typically found in industrial gas turbines. A model incorporating diffusion, equilibrium thermodynamics and oxidation has been developed to simulate the microstructural evolution within a multi-layered coating system. The phase and concentration profiles ...

#### The synthesis and characterization of Cu2ZnSnS4 thin films from melt reactions using xanthate precursors

Kesterite, Cu2ZnSnS4 (CZTS), is a promising absorber layer for use in photovoltaic cells. We report the use of copper, zinc and tin xanthates in melt reactions to produce Cu2ZnSnS4 (CZTS) thin films. The phase of the as-produced CZTS is dependent on decomposition temperature. X-ray diffraction patterns and Raman spectra show that films annealed between 375 and 475 °C are ...

#### Understanding heterogeneity in Genesis diamond-like carbon film using SIMS analysis of implants

An amorphous diamond-like carbon film deposited on silicon made at Sandia National Laboratory by pulsed laser deposition was one of several solar wind (SW) collectors used by the Genesis Mission (NASA Discovery Class Mission #5). The film was ~1 μm thick, amorphous, anhydrous, and had a high ratio of sp 3–sp 2 bonds (>50%). For 27 months of exposure to space at the first Lagrange ...

#### Nickel sulfide thin films and nanocrystals synthesized from nickel xanthate precursors

Nickel sulfide thin films and nanocrystals stabilized with oleylamine ligands are prepared from two different nickel xanthates as single-source precursors, which decompose at approx. 180 °C, and are thereby converted into nickel sulfide. These nickel xanthates comprise branched alkyl moieties allowing the choice of a wide range of nonpolar organic solvents for the processing to ...
