Appraisal of Pulse-Shaping Technique in Split Hopkinson Pressure Bar Tests for Brittle Materials
Split Hopkinson pressure bar (SHPB) technique has been frequently used to measure the uniaxial compressive stress–strain relation of brittle materials at intermediate strain-rates where pulse-shaping technique is employed to improve the stress uniformity and maintain a nearly constant strain-rate in the specimen durin…
A phosphorus‐containing inorganic compound as an effective flame retardant for glass‐fiber‐reinforced polyamide 6
Abstract A novel inorganic compound, aluminum hypophosphite (AP), was synthesized successfully and applied as a flame retardant to glass‐fiber‐reinforced polyamide 6 (GF–PA6). The thermal stability and burning behaviors of the GF–PA6 samples containing AP (flame‐retardant GF–PA6) were investigated by thermogravimetric…
Synthesis And Characterization Of Highly Crystalline Polyaniline Film Promising For Humid Sensor
Polyaniline (PANI) was prepared in emeraldine via chemical oxidation method using CuSO4 as initiating agent. The chemical characterizations were made using UV-vis (ultraviolet-visible spectrophotometry), FT-IR (Fourier transform spectroscopy), TG-DTA (thermo-gravimetric/differential thermal analysis), ESI-MS (electros…
Biomedical applications of nanostructured porous silicon: a review
Current fabrication and characterization techniques allow the development of nanostructured systems with controlled size, shape and composition. Additionally, modifications can be made to these nanosystems to better suit their integration with biological systems, leading to such interesting properties as enhanced aque…
Self-propelled jumping drops on superhydrophobic surfaces
We report a self-propelled jumping phenomenon for coalescing drops on superhydrophobic surfaces. The spontaneous motion is powered by surface energy released upon coalescence. On a horizontal, chilled superhydrophobic surface with an apparent contact angle close to 180°, coalescing drops of water condensate spontaneou…
Use of Jiles–Atherton and Preisach Hysteresis Models for Inverse Feed-Forward Control
Hysteresis effects hinder the accurate control of electromagnetic actuators and require auxiliary sensors for properly determining the hysteretic system state. The physics-based Jiles-Atherton and the phenomenological Preisach hysteresis models provide powerful means to describe the magnetic hysteresis and its inverse…
Two dimensional electron gases in polycrystalline MgZnO/ZnO heterostructures grown by rf-sputtering process
This paper reports the formation of two-dimensional electron gas (2DEG) in rf-sputtered defective polycrystalline MgZnO/ZnO heterostructure via the screening of grain boundary potential by polarization-induced charges. As the MgZnO thickness increases, the sheet resistance reduces rapidly and then saturates. The enhan…
Size Effect of Nanograined BaTiO3 Ceramics Fabricated by Aerosol Deposition Method
We demonstrated the size effect of nanograined BaTiO 3 ceramics using freestanding BaTiO 3 thick films fabricated by the aerosol deposition (AD) method. Dense BaTiO 3 thick films fabricated by the AD method were crystallized and detached from the SrTiO 3 substrate by annealing treatment at 600 °C, and then the grain s…
Noncentrosymmetric Structure of LuFeO3 in Metastable State
The crystal structure of metastable LuFeO 3 synthesized by containerless processing has been revealed to be a non-centrosymmetric structure (space group P 6 3 c m ) by analyzing the high-energy synchrotron-radiation powder-diffraction data using the maximum entropy method (MEM)/Rietveld method. The structural characte…
Green synthesis and characterization of palladium nanoparticles and its conjugates from solanum trilobatum leaf extract
Abstract An important area of research in nanotechnology deals with the synthesis of nanoparticles of different chemical compositions, sizes and controlled monodispersity. Currently, there is a growing need to develop environmentally benign nanoparticle synthesis in which no toxic chemicals are used in the synthesis p…
Suspension Culture of Mammalian Cells Using Thermosensitive Microcarrier that Allows Cell Detachment without Proteolytic Enzyme Treatment
Microcarriers are used to expand anchorage-dependent cells in large-scale suspension bioreactors. Proteolytic enzyme treatment is necessary to detach cells cultured on microcarriers for cell harvest or scale-up, but the enzyme treatment damages the cells and extracellular matrices and complicates the culture process.…
Para-Derivatized Pybox Ligands As Sensitizers in Highly Luminescent Ln(III) Complexes
New complexes of pyridine-bis(oxazoline) derivatized with -H, -OMe, and -Br at the para position of the pyridine ring with Eu(III) and Tb(III) have been isolated. These are highly luminescent in the solid state, regardless of the ligand-to-metal ratio. Several of the metal complexes were isolated and characterized by…
Sintering of Magnesium
Abstract Sintering of magnesium powder is strongly inhibited by a stable oxide layer that is formed immediately after exposure to air. In contrast to e.g. titanium, no solubility of oxygen in solid magnesium is reported; therefore, the oxide layer is not dissolved during sintering. In this study, different methods are…
Stable Charge-Transfer Doping of Transparent Single-Walled Carbon Nanotube Films
Single walled carbon nanotube (SWCNT) films are candidates for use as transparent electrodes, especially where low-cost, flexible materials are desired. Chemical doping is a critical step in fabricating conductive films as doping substantially decreases the sheet resistance within SWCNTs and at tube−tube junctions. De…
Synthesis and characterization of silver/talc nanocomposites using the wet chemical reduction method
In this study, silver nanoparticles (Ag-NPs) were synthesized using the wet chemical reduction method on the external surface layer of talc mineral as a solid support. Silver nitrate and sodium borohydride were used as the silver precursor and reducing agent in talc. The talc was suspended in aqueous AgNO(3) solution.…
Wettability, Shrinkage and Color Changes of Araucaria angustifolia After Heating Treatment
The effects of thermal treatment on the wettability and shrink resistance of Araucaria angustifolia (Parana pine) were studied from 20 to 200 °C. The contact angles of water droplets on untreated and heat-treated samples were measured by the sessile drop method in the grain of heartwood and sapwood cut in the radial,…
Shear friction capacity of recycled concretes
The aim of this research was to determine the behavior of recycled concrete in response to the phenomenon of shear transfer. To perform it, a conventional control concrete and a concrete with 50% recycled coarse aggregate were designed. An additional goal was to shed light on how this behavior is modified with a pozzo…
The alkali–aggregate reaction for various aggregates used in concrete
The aim of this work is to contribute to the knowledge of the interactions between aggregates and the components of the interstitial phase of concrete and to determine whether those aggregates that are subsequently used in the manufacture of concrete are reagents and are therefore likely to undergo a progressive deter…
