New therapies are needed to prevent heart failure after myocardial infarction (MI). As experimental treatment strategies for MI approach translation, safety and efficacy must be established in relevant animal models that mimic the clinical situation. We have developed an injectable hydrogel derived from porcine myocar…
Brought to light: Thin, planar nanojunctions between layered MoS2 and graphitic CN (g-CN) were constructed and allowed fast charge separation across the junction interfaces to facilitate hydrogen photosynthesis. This research represents a proof of concept for the rational fabrication of thin interfacial junctions betw…
We report on the structural and electrical properties of ZnO films grown on surface-treated GaN/Al2O3substrates by chemical bath deposition. X-ray diffraction analysis indicated that the ZnO films had a single-crystalline wurtzite structure withc-axis orientation. The ZnO film exhibited n-type conduction with a carrie…

In this study we report a new method for the synthesis of a silica monolithic column bed with bimodal pores (throughpores and mesopores). The template induced synthesis method was used to direct bimodal pores simultaneously instead of the usual post base-treating method. Block polymer Pluronic F127 was chosen as a dua…
Frequency dependence of the dielectric response is studied for ferroelectric bilayer thin-film capacitors under a cyclic bias voltage. The approach used in this work enables probing strong dielectric nonlinearities at millisecond and microsecond time scales during polarization switching in thin films. The frequency-de…
The relationship between the electrical properties and crystallographic quality (crystallinity) of electroplated copper thin-film interconnections was investigated. The crystallinity of the grains and grain boundaries of the interconnections was evaluated on the basis of the image quality (IQ) value obtained by electr…
The phase behavior of gradient copolymers is studied theoretically using random phase approximation (RPA) and self-consistent field theory (SCFT), focusing on the effects of monomer sequence distribution, or compositional polydispersity, of the polymer chains. The stability of the disordered phase is examined using RP…
Abstract Monte–Carlo kinetic simulations are performed to study exchange reactions in PET/PEN blends. Chain distribution of the blend is simulated at various mixing conditions. The average length of PET and PEN repeating units decreases with increasing exchange reactions. Derivative of heat flow is modeled at Tg regio…
Iron-containing bismuth silicate glasses with compositions 60SiO2·( 100−x ) Bi2O3·xFe2O3 have been prepared by conventional melt-quenching technique. The amorphous nature of the glass samples has been ascertained by the X-ray diffraction. The density (d) has been measured using Archimedes principle, molar volume ( Vm…
An ac conductivity as well as dielectric relaxation property of La 2 NiO 4.1 is reported in the temperature range of 77 K–130 K and in the frequency range of 20 Hz–1 MHz. Complex impedance plane plots show that the relaxation (conduction) mechanism in this material is purely a bulk effect arising from the semiconducti…
Abstract A material with low dielectric constant was produced using nanoparticle phosphotungstic acid (PWA) modified by the silane coupling agent γ‐aminopropyltriethoxysilane (KH‐550) dispersed in a poly(aryl ether ketone) containing (3‐trifluoromethyl) phenyl side groups (FPEEK) matrix synthesized with (3‐trifluorome…
The physicochemical properties of Ughelli bentonite was modified by nitric acid activation to improve its performance. The bentonite mineral was reacted with different concentrations of nitric acid ranging from 2 to 16 mol.L-1. The reactions were performed at different times and temperatures to study the process kinet…
The Anderson impurity problem is considered for a graphene bilayer subject to a gap-opening bias. In-gap localized states are produced even when the impurity level overlaps with the continuum of band electrons. The effect depends strongly on the polarity of the applied bias as long as hybridization with the impurity o…
The unique properties of graphene, a single-atom-thick sheet of sp2-hybridized carbon atoms with honeycomb structure, have ensured it is the subject of significant number of papers detailing its synthesis, properties and applications. In this chapter, the recent trends in the synthesis methodologies of graphene-inorga…
The microwave permeability of flake-shaped particles is investigated using a shorted microstrip setup. Several characterizations using two distinct field configurations, with and without the presence of a static field, are performed to provide information about the magnetization dynamics of this new material. A first…
Resistance measurements have been performed for a two-dimensional magnetic-field-induced superconductor λ-(BETS)2FeCl4, where BETS denotes bis(ethylenedithio)tetraselenafulvalene. In magnetic fields along the \(c\)-axis (parallel to the conducting layers), characteristic dip structures in the interlayer resistance are…
Thin films of gallium/antimony alloys are promising candidates for phase change memories requiring rapid crystallization at high crystallization temperatures. Prominent examples are the stoichiometric form GaSb and alloys near the eutectic composition GaSb(7), but little is known about their amorphous structures or th…
The early stages of the self-assembly of peptide hydrogels largely determine their final material properties. Here we discuss experimental methodologies for monitoring the self-assembly kinetics which underpin peptide hydrogel formation. The early stage assembly of an enzyme-catalysed Fmoc-trileucine based self-assemb…
In this chapter, we describe similar crystal growth features in inorganic and biogenic carbonates and phosphates formed in natural environments and in laboratory experiments. We focus on the importance of the kinetics on the crystal habit of carbonates and phosphates precipitated in biological and abiotic systems. We…
