As a sort of scalable precursor of graphene, single-layer graphene oxide (GO) has received widespread attention. However, producing dried GO powder which can redisperse in solvents on a molecular level is still under challenge. Here, we have developed a strategy to obtain flower-shaped GO powder (fGO) via a low-temper…
Disordered CoFeCrAl and CoFeCrSi0.5Al0.5 alloys have been investigated experimentally and by first-principle calculations. The melt-spun and annealed samples all exhibit Heusler-type superlattice peaks, but the peak intensities indicate a substantial degree of B2-type chemical disorder. Si substitution reduces the deg…
A cyclic octapeptide composed of hydroxy-functionalized γ-amino acids folds in a "V-shaped" conformation that allows the selective recognition of anions such as chloride, nitrate, and carbonate. The process involves the simultaneous self-assembly of six peptide subunits and the recognition of four anions to form a tet…
Abstract In this letter, we propose a magneto-inductive wave (MIW) metamaterial cavity for enhanced mid-range wireless power transfer (WPT) applications. Cavity operation is achieved by controlling the propagation of MIWs at lower megahertz frequencies. The cavity is realized by omitting a cell and thereby breaking th…
The existence of electric dipole active magnetic excitations, or electromagnons, in rare-earth orthoferrites was theoretically predicted more than two decades ago but their experimental observation has not been confirmed until now. In this work, magnetic modes in DyFeO${}_{3}$ single crystals were studied at low tempe…
High Resolution Image Download MS PowerPoint Slide We study the conformation of graphene oxide as the filler in nanocomposites of polystyrene and poly(methyl methacrylate) using inverse-space scattering techniques and atomic force microscopy. By subtracting the polymer scattering to estimate the scattering contributio…
The detection of secondary explosive molecules (e.g., ANTA, FOX-7, and CL-20) using Ag decorated ZnO nanostructures as surface enhanced Raman scattering (SERS) probes is demonstrated. ZnO nanostructures were grown on borosilicate glass substrates by rapid thermal oxidation of metallic Zn films at 500 °C. The oxide nan…
Thermal simulation equipment (TSE) was recently developed to simulate the solidification process in the industrial continuous casting of slab. The grain growth, solid-liquid interface movement, and columnar-to-equiaxed transition (CET) in the continuous casting process can be reproduced using this equipment. The curre…
We show that superconductors with broken time-reversal symmetry have very specific magnetic and electric responses to inhomogeneous heating. A local heating of such superconductors induces a magnetic field with a profile that is sensitive to the presence of domain walls and crystalline anisotropy of superconducting st…
The realization of a controllable metamagnetic transition from AFM to FM ordering would open the door to a plethora of new spintronics based devices that, rather than reorienting spins in a ferromagnet, harness direct control of a materials intrinsic magnetic ordering. In this study FeRh films with drastically reduced…
Mn-doped TiO2 micro/nanostructure porous film was prepared by anodizing a Ti-Mn alloy. The film annealed at 300 °C yields the highest areal capacitance of 1451.3 mF/cm(2) at a current density of 3 mA/cm(2) when used as a high-performance supercapacitor electrode. Areal capacitance retention is 63.7% when the current d…
BACKGROUND: Targeted hepatocellular carcinoma (HCC) therapy was carried out to improve the efficacy of liver cancers. The aim of this study was to develop transferrin (Tf) modified, self-assembled polymeric nanoparticles for co-delivery doxorubicin (DOX) and cisplatin (DDP), to achieve combination tumor therapy. METHO…
High Resolution Image Download MS PowerPoint Slide Complementary interaction force measurements between an atomic force microscope (AFM) tip or colloid probe and a weak polybasic brush have been shown to yield a number of fundamental characteristics of the brush and its response to the presence of specific anions in a…
Gel spinning of UHMWPE fibers using low molecular weight polybutene (PB) as a new spin solvent was investigated. A 98/2 wt% PB/UHMWPE gel exhibits a melting temperature around 115°C and shows large‐scale phase separation upon cooling the solution to room temperature. The resulting precursor fiber from this gel was hot…
Fabricating ideal scaffolds for bone tissue engineering is a great challenge to researchers. To better mimic the mineral component and the microstructure of natural bone, several kinds of materials were adopted in our study, namely gelatin, polycaprolactone (PCL), nanohydroxyapatite (nHA), and bone powder. Three types…
Direct electrodeposition of mercury onto gold nanorods on an ITO substrate, without reducing agents, is reported. The growth of single gold amalgam nanoalloy particles and subsequent stripping was monitored in real-time monitoring by plasmonic effects and single-nanoparticle dark-field spectroelectrochemistry techniqu…
Responsive surfaces: a review of the dependence of protein adsorption on the reversible volume phase transition in stimuli-responsive polymers. Specifically addressed are a widely studied subset: thermoresponsive polymers. Findings are also generalizable to other materials which undergo a similarly reversible volume p…
AIM: The poly(amidoamine) dendrimers modified with Buthus martensii Karsch chlorotoxin (BmK CT) were developed as a (131)I delivery system for glioma-targeted imaging and therapy. MATERIALS & METHODS: Dendrimers before and after labeling (131)I were synthetized and their physicochemical properties were tested. The tar…
Materials for tissue engineering have to be biocompatible and have to support cell adhesion, proliferation and differentiation. Additionally, in case of soft tissue engineering the mechanical properties have to accommodate that of the tissue with mechanical integrity until the artificial scaffold is replaced by natura…
We introduce an effective tight-binding model to discuss penta-graphene and present an analytical solution. This model only involves the π-orbitals of the sp(2)-hybridized carbon atoms and reproduces the two highest valence bands. By introducing energy-dependent hopping elements, originating from the elimination of th…
