Tuning effects of the band filling and impurity distribution on the anomalous Hall effect are demonstrated in epitaxial face centered cubic Ni x Co 1− x (002) films through the alloy composition. The anomalous Hall resistivity obeys the conventional scaling law, i.e. . It is interesting to find that in addition to the…
The change of magnetization states by spin transfer torque brought momentum to research on magnetic random access memory (MRAM), however, there is still a need for improvement of memory performances. The conventional multi-bit per cell (MBPC) scheme has the potential of increasing the storage capacity of MRAM but the…
Bioengineered bladder tissue is needed for patients with neurogenic bladder disease as well as for cancer. Current technologies in bladder tissue engineering have been hampered by an inability to efficiently initiate blood supply to the graft, ultimately leading to complications that include graft contraction, ischemi…
The main roadblock for EUV lithography to be successfully adopted for high-volume manufacturing is the current lack of source power. One way to help mitigate this problem is to optimize the photoresist by increasing both absorbance and quantum yield. The latter represents the ratio between the sums of generated acids…
Magnetic iron oxide nanoparticles on a zeolite template have been synthesized using wet chemical approach. The average particle size initially decreases from 8.5 to 6 nm (increasing zeolite concentration from 0 to 75 mg) but increases to 11 nm for higher zeolite concentration (100 mg). Room temperature magnetization c…
Distribution of complex fluid flow is an important factor that affects the temperature distribution of the end parts in the end region of a turbogenerator. In this paper, a turbogenerator is considered as an example; the fluid flow velocity and pressure values obtained from flow network calculations are applied to the…
We have synthesized three silicon phthalocyanine dyes with different hydrophobic substituents in order to control surface energy in the solid state, aiming at selective loading of the dyes into blend films of poly(3-hexylthiophene) (P3HT) and polystyrene (PS). These three dyes are differently located at P3HT domains,…
In this study, several unsymmetrical Schiff bases and their cobalt and manganese complexes have been synthesized and characterized. The unsymmetrical Schiff bases were prepared from reaction of o-phenylendiamine derivatives with 1-hydroxy-2-acetonaphthone and then the product was reacted with the following aldehydes:…
Abstract Epoxy‐coated reinforcement (ECR) as a means of protection against chloride‐induced corrosion of steel in concrete is used in only a few countries due to doubts concerning its effectiveness. A common misconception is that possible defects in the coating are particularly weak points as these might favour high l…
By using Majorana's stellar representation, we give a clear geometrical interpretation of the topological phases of inversion-symmetric polymerized models by mapping the Bloch states of multiband systems to Majorana stars on the Bloch sphere. While trajectories of Majorana stars of a filled Bloch band exhibit quite di…

Abstract Four novel complexes, [Cu(L)2(NH3)2(H2O)2] (1), {[Cu(L)2(H2O)2]·2H2O}n (2), {[Zn(L)2(H2O)2]·2H2O}n (3), and {[Fe(L)2(H2O)2]·2H2O}n (4) (HL = 2‐{[4‐amino‐3‐(pyridin‐4‐yl)‐4,5‐dihydro‐1H‐1,2,4‐triazol‐5‐yl]thio}acetic acid) were synthesized and characterized by single‐crystal X‐ray diffraction analysis. Complex…
Solid bases, such as SBA-15-oxynitrides, have attracted considerable interest for potential applications as catalysts in important industrial processes. Reported herein is that by simply tuning the temperature of nitridation (ammonolysis), the catalytic activity of these solid bases can be enhanced. Solid-state NMR sp…
Cotton quality, a major factor determining both cotton profitability and marketability, is affected by not only the overall quantity of but also the type of the foreign matter. Although current commercial instruments can measure the overall amount of the foreign matter, no instrument can differentiate various types of…
Fracture toughness of La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3‐δ ( LSCF ) in both bulk and film forms after sintering at 900°C to 1200°C was measured using both single‐edge V‐notched beam ( SEVNB ) 3‐point bending and Berkovich indentation. FIB / SEM slice‐and‐view observation after indentation revealed the presence of Palmqvi…
Quantum chemical methods are used to study the solvent effects on the spectra of indole and a series of methyl-substituted indoles. We focus on the low-lying L(a) and L(b) states and study their interplay. We find that the solvent mainly affects emission from the L(a) state, by stabilizing its energy in its excited-st…
Abstract Metal–organic frameworks (MOFs) are shown to be good examples of a new class of crystalline porous materials for guest encapsulation. Since the encapsulation/release of guest molecules in MOF hosts is a reversible process in nature, how to prevent the leaching of guests from the open pores with minimal and no…

The homogeneous oxidation of m -xylene (MX) to isophthalic acid (IPA) with acetic acid as solvent catalyzed by Co–Mn–Br catalyst was investigated at temperatures from 448.2 to 466.2 K by semicontinuous and continuous experiments. Based on the free radical chain reaction mechanism of hydrocarbon, one simplified kinetic…
Abstract Small‐molecule‐based multimodal and multifunctional imaging probes play prominent roles in biomedical research and have high clinical translation ability. A novel multimodal imaging platform using base‐catalyzed double addition of thiols to a strained internal alkyne such as bicyclo[6.1.0]nonyne has been esta…
