We present the design, fabrication and experimental demonstration of an electrically active absorber at microwave frequency. Unlike those proposed before, simulation and experiment data present that its working frequency and absorbing intensity can be both but separately controlled. The electromagnetic coupling analys…
Graphane and its derivatives are stable and extremely thin, wide band gap semiconductors that promise to replace conventional semiconductors in electronics, catalysis, and energy applications, greatly reducing device size and power consumption. In order to be useful, band-gap excitations in these materials should be l…
To explore the effect of delocalization in the Fe(NO)(2) unit on possible linkage isomerism of ambidentate ECN(-) ligands, E = S and O, anionic DNICs, dinitrosyl iron complexes, (SCN)(2)Fe(NO)(2)(-) (1) and (OCN)(2)Fe(NO)(2)(-) (2) were synthesized by the reaction of in situ-generated [Fe(CO)(2)(NO)(2)](+) and PPN(+)E…
Stereological analysis has been coupled with transmission electron microscope (TEM) orientation mapping to investigate the grain boundary character distribution in nanocrystalline copper thin films. The use of the nanosized (<5 nm) beam in the TEM for collecting spot diffraction patterns renders an order of magnitude…
The paper presents the general review of application of composite materials including the distinction of their specific features. Also short overview of history of composite materials is conducted. The major subject is the explanation, what is advantage of the composites over traditional materials. Additionally, a lot…
An efficient near-infrared (NIR) phosphor LiSrPO(4):Eu(2+), Pr(3+) is synthesized by solid-state reaction and systematically investigated using x-ray diffraction, diffuse reflection spectrum, photoluminescence spectra at room temperature and 3 K, and the decay curves. The UV-Vis-NIR energy transfer mechanism is propos…
The catalytic effects of perdeuterating the pyridoxal phosphate-dependent enzyme alanine racemase from Geobacillus stearothermophilus are reported. The mass of the heavy perdeuterated form is ~5.5% greater than that of the protiated form, causing kinetic isotope effects (KIEs) of ~1.3 on k(cat) and k(cat)/K(M) for bot…
Abstract Self‐assembling dendrons are biologically inspired complex systems that can form self‐organized periodic arrays in the bulk state. Here we adopt the point of view of Constitutional Dynamic Chemistry (CDC) to discuss the design and properties of self‐assembling dendrimers and dendronized structures. Among othe…
This study aims to develop, for the first time, thermoplastic polyurethane (TPU) microcellular composite fibers via an extrusion foaming process using supercritical CO 2 as a blowing agent. Results showed that by employing organically modified montmorillonite clay nanoparticles (Cloisite TR 20A) in the matrix at an op…
In Insulated gate Bipolar Transistor (IGBT) modules, ceramic substrates are used as insulation between semiconductor chips and the ground potential. The substrate, semiconductor chips and connections are covered with silicone gel to prevent partial discharges (PDs) from occurring. In this work, partial discharges are…
This contribution reports the synthesis of a poly(amide)-based dendrimer functionalized at the termini with a membrane-interacting peptide derived from the herpes simplex virus (HSV) type 1 glycoprotein H, namely gH625-644. This peptide has been shown to interact with model membranes and to inhibit viral infectivity.…
Reduced activation ferritic/martensitic steel (RAFM) is recognized as the primary candidate structural material for ITER's test blanket module (TBM). To provide a material and property database for the design and fabrication of the Chinese helium cooled ceramic breeding TBM (CN HCCB TBM), a type of RAFM steel named CL…
Smart sensors embedded in packaging films for food or pharmaceuticals, and read out using RFID protocols, are an important future application of large-area organic electronics. The first steps towards flexible organic electronics were code generators for RFID tags [1]. To realize flexible smart sensors it is also esse…
Biodegradable poly(lactic acid) PLA and modified TiO2 nanoparticles (with propanoic acid) were prepared by solution blending method. Nanocomposite films containing 0.5, 2, 5 and 10 wt% of nanoparticles were characterized using scanning electron microscopy (SEM), differential scanning calorimetry (DSC), Fourier transfo…
Nanoparticles (NPs) with easily modified surfaces have been playing an important role in biomedicine. As cancer is one of the major causes of death, tremendous efforts have been devoted to advance the methods of cancer diagnosis and therapy. Recently, magnetic nanoparticles (MNPs) that are responsive to a magnetic fie…
Abstract Invited for this month′s cover are the groups of Prof. Jinzhu Chen and Prof. Longlong Ma from the Guangzhou Institute of Energy Conversion, Chinese Academy of Sciences. The image shows a bifunctional stabilizing mechanism of the composite support PANI/CNT on palladium nanoparticles in the catalyst Pd–PANI/CNT…
The primary water stress corrosion cracking (PWSCC) of Alloy 600 in a PWR has been reported in the control rod drive mechanism (CRDM), pressurizer instrumentation, and the pressurizer heater sleeves. Recently, two cases of boric acid precipitation that indicated leaking of the primary cooling water were reported on th…
Understanding how a magnetic field affects the interaction of magnetic nanoparticles (MNPs) with cells is fundamental to any potential downstream applications of MNPs as gene and drug delivery vehicles. Here, we present a quantitative analysis of how a pulsed magnetic field influences the manner in which MNPs interact…
In this paper, aligned PLGA nanofibrous scaffolds were synthesized by electrospinning for tissue engineering. Morphological characterization showed highly aligned nanofibrous morphology with nearly uniform diameter less than 200 nm and porosity reaches to 73%. The FTIR results showed no changes in the FTIR spectra whe…
In-plane and out-of-plane arrangements of carbon atoms in graphene layers play critical roles in the fundamental physics and practical applications of these novel two-dimensional materials. Here, we report initial results on the edge/crystal orientations and stacking orders of bi- and tri-layer graphene (BLG and TLG)…
