The quest for small-scale, remotely controlled soft robots has led to the exploration of magnetic and optical fields inducing shape morphing in materials. Magnetic stimulus excels when navigation confined or optically opaque environments is required. Optical stimulus, turn, boasts superior spatial precision individual control over multiple objects. Herein, we bring these two methodologies together present a monolithic liquid crystal elastomer (LCE) system that synergistically combines...
In this paper we propose various current collector alternatives to be used in flexible supercapacitors with aqueous electrolyte when low equivalent series resistance (ESR) is required. The material should corrosion resistant contact the saline electrolyte. Simultaneously it have high electrical conductivity. addition, environmental and cost aspects must taken into account. We report collectors made of two different thicknesses graphite foil (25 µm 150 µm) aluminium coated inks. These...
Particle emissions from marine traffic affect significantly air quality in coastal areas and the climate. The particle were studied a 1.4 MW engine operating on low-sulfur fuels natural gas (NG; dual-fuel with diesel pilot), oil (MGO) (MDO). emitted particles characterized respect to number (PN) emission factors, PN size distribution down nanometer scale (1.2–414 nm), volatility, electric charge, morphology, elemental composition. of fresh exhaust was bimodal for all fuels, nucleation mode...
Additive manufacturing (AM) is a relatively new method that can produce complex geometries and optimized shapes with less process steps. In addition to distinct microstructural features, residual stresses their formation are also inherent AM components. components require several post-processing steps before they ready for use. To change the traditional AM, comprehensive characterization needed verify suitability of On very demanding corrosion atmospheres, question does lower or eliminate...
This paper aims to introduce small angle X-ray scattering (SAXS) as a promising technique for measuring size and distribution of TiO2 nanoparticles. In this manuscript, pulsed laser ablation in liquids (PLAL) has been demonstrated quick simple synthesizing nanoparticles directly into deionized water suspension from titanium targets. Spherical with diameters the range 4-35 nm were observed transmission electron microscopy (TEM). diffraction (XRD) showed highly crystalline that comprised two...
Layered structure graphene oxide/methylcellulose composite films with excellent mechanical and gas barrier properties were fabricated by a simple solvent evaporation assisted assembly.
Alumina (Al2O3) remains one the most important engineering ceramic for industrial applications. In addition to α phase, transition alumina phases have interesting characteristics. Controlling obtained phase structure from melt requires processes with extreme cooling rates and therefore limits tailoring capabilities. This study investigates how rate of pure affects its microstructural properties in plasma-based processing. The paper reports changes micron sized granulated particles...
Abstract Polymer–metal hybrids are replacing steel structures in many applications. Combining metals and plastics is, however, complicated because they have very different physical chemical characteristics. This study characterizes plastic–metal adhesion insert-injection-molded hybrids. Diaminofunctional silane was used as a coupling agent between thermoplastic urethane stainless steel. Before treatment, various surface treatments, including electrolytic polishing oxidation were applied to...
Engineering artificial skin constructs is an ongoing challenge. An ideal material for hosting cells still to be discovered. A promising candidate low-cost cellulose, which commonly fabricated in the form of a mesh and applied as wound dressing. Unfortunately, structure topography current cellulose meshes are not optimal cell growth. To enhance surface physicochemical properties commercially available mesh, we coated with wood-derived nanofibrils (CNFs). Three different types coatings...
Two steels, ferrite and ferrite-pearlite were thoroughly characterized by a multi-instrumental microscopy techniques to get detailed information about their microstructure magnetic structure. Microstructural features act as pinning sites for the motion of domain walls (DWs) leading changes in magnetization sample. This phenomenon is basis industrially relevant non-destructive Barkhausen noise (BN) technique. With force (MFM), using bulk samples, Lorentz microscopy, thin films, we noticed...
