Attempts to explain correlated‐electron superconductivity (SC) have largely focused on the proximity of the superconducting state to antiferromagnetism. Yet, there exist many correlated‐electron systems that exhibit insulator‐superconducting transitions where the insulating state exhibits spatial broken symmetry diffe…
In-situ electromigration tests have been performed inside a scanning electron microscope on 30 nm wide single damascene interconnects without vias, where a good resolution was obtained and drift velocities during void growth could be measured at 300 °C. These tests showed direct evidence that the cathode end of the li…
CoNi gradient binary-alloy nanowires are prepared in porous anodic aluminum oxide (AAO) template via electrodeposition. The coercivity and remanence of the nanowires are of high anisotropy due to the axial deposition of the magnetic compositions. The magnetocrystalline anisotropy and crystalline structure of the nanow…
The corrosion behavior of aluminum and mild steel in hydrochloric acid medium was studied using a nicotinic acid hydrazide as inhibitor by potentiodynamic polarization, electrochemical impedance spectroscopy technique and gravimetric methods. The effects of inhibitor concentration and temperature were investigated. Th…
A host framework for inclusion of various guest molecules was investigated by preparation of inclusion crystals of 1,8-bis(4-aminophenyl)anthracene (1,8-BAPA) with organic solvents. X-ray crystallographic analysis revealed construction of the same inclusion space incorporating 1,8-BAPA and eight guest molecules includ…
Abstract The properties of polyamide 6 (PA6)/poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) blends (60/40, wt%) compatibilized by poly(styrene-co-maleic anhydride) (SMA) were studied. The addition of SMA can form an in situ copolymer, SMA- graft -PA6. The SMA- graft -PA6 copolymer actually plays a key role as a compatib…
To fabricate multiwalled carbon nanotubes (MWCNTs)/tetrafluoroethylene‐propylene elastomer (TFEP) nanocomposite, the surface architecture of MWCNTs was tailored based on TFEP molecular structure. Silane coupling agent (SC) and fluorocarbon surfactant (FC) were separately used to improve the interaction and compatibili…
The electronic and magnetic properties of boron nitride nanoribbons (BNNRs) with square-octagon (4 | 8) line defects (LD-(4 | 8)), parallel to their edges, have been investigated by first-principles calculations. It is found that the zigzag type LD-(4 | 8) BNNR with boron terminated edges is an antiferromagnetic (AFM'…
A one‐step method was developed for preparing Ag 2 S quantum dots (QDs) using a common protein [bovine serum albumin (BSA)] to entrap QDs precursors (BSA–Ag + ). Fluorescence (FL) and ultraviolet spectra showed that the molar ratio of Ag + /BSA, temperature, and pH are the crucial factors for the quality of QDs. The Q…
Purpose – This work was focused upon the main factors that influence the formation of a hydroxypropyl-β-cyclodextrin (HP-β-CD) supramolecular complex with octadecylamine (ODA) and their optimal processing conditions. The anti-corrosion properties of the products in the simulated boiler water condensate of power plants…
Anisotropic growth is observed for homoepitaxial diamond (111) films by microwave plasma-enhanced chemical vapor deposition in the lateral growth mode. Using ex situ atomic force microscopy, we clearly show the motion of single bi-atomic layer steps owing to homoepitaxial diamond growth for the first time. An atomisti…
In this paper, organic solvent electrolytes were prepared by a mixture of propylene carbonate (PC), dimethyl carbonate (DMC), tetraethylammonium tetrafluoroborate (<TEX>$TEABF_4$</TEX>)s to evaluate the ionic properties of propylene carbonate (PC)/dimethyl carbonate (DMC) mixtures as solvents for a capacitor applicati…
Three drug delivery systems viz. doxycycline hyclate entrapped poly (vinyl alcohol) (PVA) microspheres (DM), composite fibers of doxycycline hyclatepoly (3-hydroxybutyric acid) (PHB) electrospun fibers (DF), and doxycycline hyclateloaded poly (vinyl alcohol) (PVA) microspheres sandwiched between composite fibers consi…
Individual single-walled carbon nanotubes (SWNTs) were suspended in water using amphipathic β-sheet peptides of the general sequence Ac-(XKXE) 2 -NH 2 . By substituting natural and nonnatural amino acids of varying aromatic and hydrophobic character in the X position, the interactions between the peptide and the nanot…
Mg–(4–x)Nd–xGd–0·3Sr–0·2Zn–0·4Zr (wt-%, x = 0, 1, 2 and 3) alloys were prepared by gravity casting. Microstructure was analysed by X-ray diffraction, optical microscopy and scanning electron microscopy respectively. The α-Mg and Mg41Nd5 phases existed in the as cast alloys with 4% and 3% Nd addition, while the new Mg3…
The disulfide bond is unusual in natural products and critical for thermal stability, cell permeability and bioactivity. DepH from Chromobacterium violaceum No. 968 is an FAD-dependent enzyme responsible for catalyzing the disulfide bond formation of FK228, an anticancer prodrug approved for the treatment of cutaneous…
The effects of pore size on direction-averaged radiative properties of three-dimensionally ordered macroporous (3DOM) cerium dioxide (ceria) particles are investigated in the spectral range of 0.3-10 μm. The particles are of spherical shape and contain interconnected pores in a face-centered cubic lattice arrangement.…
From ellipsometry measurements, Pye and Roth [Phys. Rev. Lett. 107, 235701 (2011)] presented evidence of the presence of two glass transitions originating from two distinctly different and simultaneous mechanisms to reduce the glass transition temperature within freestanding polystyrene films with thickness less than…
Recent Advances in Computational Design of Organic Materials for Corrosion Protection of Steel in Aqueous Media
In this work, we present a method for the incorporation of anisotropic colloidal nanocrystals of many different shapes in silica in a highly controlled way. This method yields a uniform silica shell, with thickness tunable from 3 to 17 nm. The silica shell perfectly adapts to the shape of the nanocrystals, preserving…
