Efficiency is defined as η = |Q|/|W| in order to investigate the electrical work |W| associated with electrocaloric heat |Q|. This materials parameter indicates that polymer films are slightly more energy efficient than ceramic films, and therefore both species of material remain candidates for future cooling applicat…
ABSTRACT Synthesis of Fe 3 O 4 /polyaniline (PANI) core/shell hybrid microspheres through an in situ polymerization route with the 300 nm Fe 3 O 4 microspheres as the cores and nucleation sites for PANI is reported. PANI shell thickness, from 30 nm to 120 nm, can be controlled by modulating the weight ratio of aniline…
A dense, conformal, thin-film coating of Pr0.75Sr0.2MnO3−δ (PSM) and PrSrCoMnO6–δ (PSCM) on a state-of-the-art La0.6Sr0.4Co0.2Fe0.8O3−δ (LSCF)-based cathode for solid oxide fuel cells (SOFC) has drastically enhanced the electro-catalytic activity and stability of the cathode, suggesting that they are excellent electro…
A new type of absorber, a four-tined fish-spear-like resonator (FFR), constructed by the two-photon polymerization process, is reported. An absorbance of more than 90% is experimentally realized and the resonance occurs in the space between the tines. Since a continuous layer of metallic thin film covers the structure…
Abstract Based on the best peak theromoelectric figure‐of‐merit value ( ZT ) of ca. 0.8 in Hf 0.5 Zr 0.5 CoSb 0.8 Sn 0.2 and ca. 1 in Hf 0.8 Ti 0.2 CoSb 0.8 Sn 0.2 , the effect of Ti on thermoelectric properties is studied in (Hf, Zr, Ti)CoSb 0.8 Sn 0.2 , with the aim of further improving the ZT and reducing the usage…
The first experimental realization of a magnetic M(n+1)AX(n) (MAX) phase, (Cr(0.75)Mn(0.25))(2)GeC, is presented, synthesized as a heteroepitaxial single crystal thin film, exhibiting excellent structural quality. This self-organized atomic laminate is based on the well-known Cr(2)GeC, with Mn, a new element in MAX ph…
Poly(ε-caprolactones) (PCLs) belong to the first generation of synthetic aliphatic polyesters. Their biodegradability motivated their extensive exploration as resorbable materials, particularly in controlled drug release applications. While PCL fell out of fashion due to the increasing popularity of shorter chain poly…
The wide scale use of copper oxide nanoparticles (CuONPs) due to their unique properties and important applications in magnetic, thermal, electrical, sensor devices, and cosmetics makes human beings more prone to the exposure of CuONPs and its potential adverse effects. Exposure to such nanoparticles is mainly through…
Silicene---the silicon counterpart of graphene---has a two-dimensional structure that leads to a host of interesting physical and chemical properties of significant utility. We report here an investigation with nonequilibrium molecular dynamics simulations of thermal transport in a single-layer silicene sheet under un…
Atomically thin hexagonal boron nitride (h-BN), as a graphene analogue, has attracted increasing interest because of many fascinating properties and a wide range of potential applications. However, it still remains a great challenge to synthesize high-quality h-BN with predetermined number of layers at a low cost. Her…
Previous studies have reported the uptake of cerium oxide nanoparticles (nCeO2) by plants, but their physiological impacts are not yet well understood. This research was aimed to study the impact of nCeO2 on the oxidative stress and antioxidant defense system in germinating rice seeds. The seeds were germinated for 10…
It was recently shown theoretically that the time-dependent heat conduction equation is form invariant under curvilinear coordinate transformations. Thus, in analogy to transformation optics, fictitious transformed space can be mapped onto (meta)materials with spatially inhomogeneous and anisotropic heat-conductivity…
Bestrahlt man Filme aus einer porösen Chitosanmatrix, die Gold-Nanostäbe und temperaturempfindliche, mit chemischen Spezies beladene Micellen enthält, wird eine lokale photothermische Umwandlung der Gold-Nanostäbe ausgelöst. Die abgestrahlte Wärme aktiviert die Freisetzung der chemischen Spezies aus den Micellen (sieh…
Carbon Nanotubes from Unconventional Resources: Part A: Entangled Multi-Walled Carbon Nanotubes and Part B: Vertically-Aligned Carbon Nanotubes
Nanocomposite thin films containing In2O3 nanoparticles were prepared by the target-attachment sputtering utilizing the InN pellets and allowing the N2 inlet gas flow during the deposition process. The x-ray photoelectron spectroscopy revealed that the chemical composition of In2O3 nanoparticles becomes InOxNy and the…
Concerns about depleting natural resources have been circulating for decades with alarming predictions that have turned out to be less than accurate. What has become clear, however, is the need for a decrease in the utility of a fossil based economy and a focus on a more sus‐ tainable one. This chapter reviews some of…
We have studied the photoexcitation dynamics of the protected gold complex Au 2 (SCH 3 )(PH 3 ) 2 +1 . In our calculations, we used a combination of the Delta Self-Consistent-Field method, Ehrenfest dynamics, and the time-dependent density functional theory. Our simulations provide insight into two types of mechanisms…
A structurally right-handed chiral sculptured thin film (STF) with a central 90 deg-twist defect was made by thermal evaporation of chalcogenide glass and the use of a serial bi-deposition process to exhibit a narrowband hole in the spectrum of the right-circularly polarized light reflected when right-circularly polar…
The electrophoretic deposition (EPD) technique was employed to fabricate the deposit with a uniform surface on the ITO glass, by using the SiO 2 -coated Ca-α-SiAlON:Eu 2+ phosphor powder. The significantly increased photoluminescence (PL) intensity in the SiO 2 -coated Ca-α-SiAlON:Eu 2+ deposit was approximately 2-tim…
Unsaturated polyester (UPE) composites reinforced with natural fiber as non-structural materials have been used in engineering. In this study, three different types of coir-reinforced UPE consisting of coir non-woven needle mat (CNM), coir mesh (CM), and coir rope (CR) were produced, and the mechanical properties, suc…
