The environmental impact of manufacturing an yttrium-doped strontium titanate (SYT) anode-supported planar solid oxide fuel cell (SOFC) system has been examined. Key components of an SOFC system including anode substrate, PEN (Positive electrode-Electrolyte-Negative electrode) structure, interconnects, and balance of…
Five derivatives of phenylthiourea namely: 1-(4-methoxyphenyl)-3-phenylthiourea (1), 1-(4-methylphenyl)-3- phenylthiourea (2), 1-(4-bromophenyl)-3-phenylthiourea (3), 1-(4-chlorophenyl)-3-phenylthiourea (4) and 1-phenylthiourea (5) have been evaluated as new inhibitors for the corrosion of carbon steel in 2 M HCl solu…
Self-organized organic nanoparticles (ONP) are adaptive to the environmental reaction conditions. ONP of fluorous alkyl iron(III) porphyrin catalytically oxidize cyclohexene to the allylic oxidation products. In contrast, the solvated metalloporphyrin yields both allylic oxidation and epoxidation products. The ONP sys…
Magnetic properties of YbAl${}_{3}$C${}_{3}$ with the hexagonal ScAl${}_{3}$C${}_{3}$-type structure have been investigated by the magnetization ($M$) and specific-heat ($C$) measurements under magnetic fields ($H$). YbAl${}_{3}$C${}_{3}$ is reported to show a spin-gap state, which is considered to be ascribed to a ma…
Epitaxial transition metal films have recently been introduced as substrates for the scalable synthesis of transferable graphene. Here, real-time microscopy is used to study graphene growth on epitaxial Ru films on sapphire. At high temperatures, high-quality graphene grows in macroscopic (>100 μm) domains to full sur…
We study theoretically the variation of the magnetic and the structural transition temperatures of the iron arsenide superconductors with external uniaxial stress. We show that the increase of the transition temperatures reported in recent experiments is compatible with a simple magnetoelastic model in which the physi…
Fabrication, optical, and field emission properties of ZnO nanorod, nanopagoda, and nanotip emitters were studied. The ZnO nanotip emitters are prepared by using combination of solution method and oxygen plasma treatment. All the emitters exhibit a highly c-axis preferred orientation crystalline structure. The nanopag…
All-metal current perpendicular to the plane (CPP) giant magnetoresistance (GMR) layers have been made within insulating matrices by direct growth to avoid sidewall damage that is caused by lithographical patterning in current vacuum-deposited devices. These insulating matrices can be made to have nanostructures with…
Abstract An electrochemical technique has been used to synthesize Ni(TCNQF 4 ) 2 (H 2 O) 2 (TCNQF 4 = 2,3,5,6‐tetrafluoro‐7,7,8,8‐tetracyanoquinodimethane). The method involves the reduction of solid TCNQF 4 immobilized on an electrode surface in contact with Ni 2+ (aq.)‐containing electrolyte. The electrochemically i…
In this study, we fabricate ZnO thin films with nano-crystalline Si (nc-Si) quantum dots (QDs) using a ZnO/Si multilayer deposition structure and a post-annealing process, and the formation of high crystallinity of Si QDs embedded in the crystalline ZnO matrix is demonstrated. For optical properties, the essential fea…
Abstract This paper presents the investigation of the behavior of a Fe–1.5 wt% Si thin sheet upon plasma‐assisted nitriding at 570°C. It had been confirmed that a very fine and intense precipitation of amorphous silicon nitride occurs as nitrogen diffuses into the sheet. The precipitates, the size of which is comprise…
Peptides with inorganic materials recognition already started to impact a wide range of surface-related technologies ranging from biomonitoring to biomedical areas. Combinatorial biology-based libraries are the initial step in tempting the directed evolution of peptides with specific interactions towards technological…
Abstract New chiral cis ‐dioxidomolybdenum compounds [MoO 2 (acac)( R N,O)] [R = Bn ( 1 ), pic ( 2 )] and [{MoO 2 (acac)} 2 {μ‐(O,N,N,O)}] ( 3 ) have been synthesized by treating [MoO 2 (acac) 2 ] withthe corresponding enantiomerically pure alcohol‐iminocompounds derived from (+)‐α‐pinene modification, ( R N,OH) (R =…
The roughness and softness of interacting surfaces are both important parameters affecting the capillary condensation of water in apolar media, yet are poorly understood at present. We studied the water capillary adhesion between a cellulose surface and a silica colloidal probe in hexane by AFM force measurements. Nan…
The two-dimensional electron gas at the interface between LaAlO(3) and SrTiO(3) has become one of the most fascinating and highly debated oxide systems of recent times. Here we propose that a one-dimensional electron gas can be engineered at the step edges of the LaAlO(3)/SrTiO(3) interface. These predictions are supp…
We present inelastic neutron scattering measurements and first principles calculations examining the intermetallic marcasite CrSb(2). The observed spin-wave dispersion implies that the magnetic interactions are strongly one-dimensional with antiferromagnetic chains parallel to the crystalline c axis. Such low-dimensio…
The Co oxide microfibers were synthesized using the electrospinning process and formed <TEX>$Co_3O_4$</TEX> microfibers after being calcined at high temperatures. The calcination temperature influenced the diameters, morphology, crystalline phase, and chemical environment of the fibers. The surface morphology of the o…
Abstract Improving the properties of biodegradable polymeric materials is needed to obtain materials competitive with current bulk plastics. Low‐molecular weight polyesters with small differences in their backbone were synthesized using a straight‐forward method and were subsequently blended with polylactide (PLA). Th…
Batch cooling crystallization is a commonly used separation and purification step in the pharmaceutical industry. Various properties of the crystalline product from a batch crystallizer can have a strong impact on the efficiency of downstream processes such as filtration and drying, on the formulation process and on t…
Lead selenide nanoparticles (PbSe NPs) have been obtained through an easy and low cost route using colloidal synthesis in aqueous solution. The synthesis was carried out at room temperature using Extran (Na₅P₃O₁₀, NaOH and H₂O) as surfactant. Hydrochloric acid (HCl) was used to eliminate the generated by-products. The…
