In this work, we presented a surface mechanical attrition treatment (SMAT)-assisted approach to the synthesis of one-dimensional copper oxide nanowires (CuO NWs) for nanodevices applications. The as-prepared CuO NWs have diameter and the length of 50 ~ 200 nm and 5 ~ 20 μm, respectively, with a preferential growth ori…
A review describing how compositional design of modified strontium titanates can lead to conductive, redox stable SOFC anodes.
Material systems that can be used to flexibly and precisely define the chemical nature and molecular arrangement of a surface would be invaluable for the control of complex biointerfacial interactions. For example, progress in antifouling polymer biointerfaces that prevent non-specific protein adsorption and cell atta…
Schematic outlining the synthesis of 5FU loaded CS/Au nanocomposite and its application.
Y 2/3 Cu 3 Ti 4 O 12 (YCTO) ceramics were successfully synthesized by sol–gel method (SG) and solid‐state method (SS), respectively. The optimized processing parameters for the syntheses of precursor powders by sol–gel process were determined as follows: the Ti ( OC 4 H 9 ) 4 concentration was 0.50 mol/L, the CH 3 COO…
In this work, the general and localized corrosion behavior of X65 carbon steel in water-saturated supercritical CO2 conditions containing O2 and SO2 at 35°C and 80 bar is evaluated. The results indicate that crystalline FeCO3 formed in the presence of water and CO2; however, the combined introduction of small concentr…
A new aromatic thiolate protected gold nanomolecule Au99(SPh)42 has been synthesized by reacting the highly stable Au144(SCH2CH2Ph)60 with thiophenol, HSPh. The ubiquitous Au144(SR)60 is known for its high stability even at elevated temperature and in the presence of excess thiol. This report demonstrates for the firs…
A complete review of all known octacyanide-based clusters with an extensive discussion of their structures, magnetic properties and multifunctionality.
Porous n-GaN has been fabricated using electrochemical anodic etching in a 0.5 M H 2 SO 4 solution in the dark for different biases (5.5–18.0 V). The pore morphology of the porous GaN shows distinctive differences: from narrow branching pores to wide parallel pores for increasing applied bias. The pore formation proce…
Elastic neutron scattering simultaneously probes both the crystal structure and magnetic order in a material. Inelastic neutron scattering measures phonons and magnetic excitations. Here, we review the average composition, crystal structure and magnetic order in the 245 family of Fe-based superconductors and in relate…
A dual stimuli-responsive multi-drug delivery system was developed for "cancer cocktail therapy". Upon UV irradiation, microcapsules could rapidly release the small-molecule drugs, and thereafter the macromolecular drugs would be released in the presence of MMP in the tumor cells. This system will find great potential…
A novel one-pot strategy for the fabrication of AIE-based FONs has been developed <italic>via</italic> a combination of RAFT polymerization and enzymatic transesterification.
A novel electrode material for a supercapacitor has been developed based on a sulfonated graphene (SG) and polypyrrole (PPy) nanocomposite synthesized by interfacial polymerization. Characterizations of the synthesized composites are performed by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD),…
Photoemission, from core levels and valence band, and low-energy electron diffraction (LEED) have been employed to investigate the electronic and structural properties of graphene-ferromagnetic (G-FM) systems, obtained by intercalation of one monolayer (1 ML) and several layers (4 ML) of Co on G grown on Ir(111). Upon…
A procedure to obtain single-electron wavefunctions within the tight-binding formalism is proposed. It is based on linear combinations of Slater-type orbitals whose screening coefficients are extracted from the optical matrix elements of the tight-binding Hamiltonian. Bloch functions obtained for zinc-blende semicondu…
We use polarized Raman scattering to probe lattice vibrations and charge ordering in 12 nm thick, epitaxially strained PrNiO_{3} films, and in superlattices of PrNiO_{3} with the band insulator PrAlO_{3}. A carefully adjusted confocal geometry is used to eliminate the substrate contribution to the Raman spectra. In fi…
The half-metallic properties of a new and promising full-Heusler compound, Zr2CoSn, are investigated by means of ab initio calculations within the Density Functional Theory framework. The ferromagnetic ordered Hg2CuTi-type crystal structure is energetically favorable and the optimized lattice parameter is 6.76 A. The…
In this work, we present experimental data demonstrating the possibility of using magnonic holographic devices for pattern recognition. The prototype eight-terminal device consists of a magnetic matrix with micro-antennas placed on the periphery of the matrix to excite and detect spin waves. The principle of operation…
We present a paradigm in constructing very stable, faceted nanotube and fullerene structures by laterally joining nanoribbons or patches of different planar phosphorene phases. Our ab initio density functional calculations indicate that these phases may form very stable, nonplanar joints. Unlike fullerenes and nanotub…
Topological phases have attracted much interest in recent years. While there are a number of three-dimensional materials exhibiting topological properties, there are relatively few two-dimensional examples aside from the well-known quantum Hall systems. Here we make materials-specific predictions for topological phase…
