Recently, the authors developed an analytical model, which has been shown valid to simulate accurately high-speed penetration onto composite materials targets. In this paper, the analytical model has been modified to analyse the impact onto hybrid composite material targets. Several equations have been corrected, alth…
Recently, it was shown that an infinite perfectly electric conducting (PEC) cylinder can be nearly completely cloaked from normally incident electromagnetic waves using a single-layer homogeneous dielectric cladding. In this letter, we introduce a simple model of the cloaked PEC cylinder, of noninfinitesimal electrica…
Nanotechnology in Wood and Wood-Composite Materials Wood is a natural, biodegradable, and renewable material that canbe used in many applications, including structural members, ornamental objects, aerospace technology, etc. Its low thermal and electrical conductivity coefficients have made it unique for specific purpo…
Two new pentavalent bismuthates, CaBi2O6−x·1.1H2O and PbBi2O6−x·H2O were prepared from NaBiO3·nH2O. Broadened X-ray powder diffraction patterns for both bismuthates were indexed to the hexagonal cell observed for PbSb2O6-type SrBi2O6. The lattice parameters were a = 0.555(1) and c = 0.530(1) nm for CaBi2O6−x·1.1H2O an…
This study focuses on the preparation of thermoplastic polyurethane (TPU) nanocomposite using Vietnamese montmorillonite (MMT) as the reinforced phase. The MMT was previously modified by intercalating polyethylene oxide (PEO) and polyvinyl alcohol (PVA) molecules between the clay layers. X‐ray diffraction (XRD) result…
The corrosion inhibition properties of 2,6-diphenylpiperidin-4-one (DPP) (1A) and 2,6-diphenyldihydro-2H-thiopyran-4(3H)-one (DPDT) (1B) for mild steel in 1 M phosphoric acid were studied using weight loss, potentiodynamic polarization and electrochemical impedance spectroscopic techniques. The effect of temperature o…
A simple method involving dyeing and electrodeposition is introduced to fabricate a three-dimensional Ni@multi-walled carbon nanotubes flexible electrode on wearable fabric.
Strong enhancement of nonlinear optical activities in 2-amino-3-nitropyridinium halides have been achieved by choosing moderate anions.
Multi-layered hollow LiYF4:Eu(3+) micro-octahedrons, with about 400 nm of single-layer thickness and 300 nm of interlayer space, have been synthesized via a facile hydrothermal route in the presence of surfactant ethylenediamine tetraacetic acid (EDTA). The mechanisms of the morphology evolution of the LiYF4:Eu micro-…
Nanosilver is currently one of the most common engineered nanomaterials and is used in many applications that lead to the release of silver nanoparticles and silver ions into aqueous systems. Nanosilver also possesses enhanced antimicrobial activity and bioavailability that may less environmental risk compared with ot…
Pressure-driven orbital reordering in the quantum magnet [CuF2(H2O)2(pyz)], (pyz = pyrazine), dramatically affects its magnetic exchange interactions. The crystal chemistry of this system is enriched with a new phase above 3 GPa, surprisingly concomitant with other polymorphs. Moreover, we discovered an unprecedented…
High-resolution electron microscopy and electron diffraction are quite useful for structural characterization of perovskite-type superconducting copper oxides on the atomic scale. Valuable information on the crystal structures and the microstructures could be obtained from observed high-resolution images if severe con…
Resistance emergency has necessitated continuous search for drugs with least toxicity, effective, affordable and eco-friendly which possess new mode of action to cater the rising emergency. In this study, T. procumbens was used for biogenic synthesis of silver nanoparticles and investigated for antibacterial and antif…
Textile industries not only consume huge volumes of water but also generate an equally alarming quantity of toxic dye rich waste water. This waste water if treated efficiently may be further reused for domestic and industrial purposes. Hence it is essential to develop, a cost effective and environmentally benign techn…
Electrochemical double layer capacitors (EDLCs) are a category of supercapacitors; devices that store charge at the interface between electrodes and an electrolyte. Currently available commercial devices have a limited operating potential that restricts their energy and power densities. Ionic liquids (ILs) are a promi…
Free-standing and flexible graphene–silver (GE–Ag) composite paper has been successfully fabricated through an evaporation of graphene oxide–AgNO 3 aqueous aerosol followed by a chemical reduction.
Single crystalline metal oxide nanowires formed via a vapor-liquid-solid (VLS) route provide a platform not only for studying fundamental nanoscale properties but also for exploring novel device applications. Although the crystal phase variation of metal oxides, which exhibits a variety of physical properties, is an i…
In this study we prepared hierarchical mesoporous silicas through evaporation-induced self-assembly using the triblock copolymer poly(ethylene oxide-b-propylene oxide-b-ethylene oxide) (F127) and the diblock copolymer poly(ethylene oxide-b-ε-caprolactone) (PEO-b-PCL) as co-templates. Small-angle X-ray scattering, tran…
Transmission electron microscopy (TEM) is a very powerful technique for materials characteriza-tion, providing information relating to morphology, composition, and crystal structure. Selected area diffraction patterns (SADPs) are crystallographic data that can be obtained using a TEM in-strument. Conventional identifi…
Diamond‐like carbon (DLC) films are deposited by bend filtered cathodic vacuum arc (FCVA) technique with DC and pulsed bias voltage. The effects of varying bias voltage on nanoindentation and nanowear properties were evaluated by atomic force microscopy. DLC films deposited with DC bias voltage of −50 V exhibited the…
