This paper presents the shape optimization of a permanent magnet synchronous motor to reduce the torque ripple and iron loss. Specifically, the harmonics of the electromotive force and cogging torque are decreased by adjusting the permanent magnet arrangement and non-uniform air gap length. In addition, an additional…

We show that for every metrizable Choquet simplex K and for every group G which is innite, countable, amenable and residually nite, there exists a Toeplitz G -subshift whose set of shift-invariant probability measures is anely homeomorphic to K . Furthermore, we get that for every integer d > 1 and every Toeplitz flow…
A new and thermally stable poly (ethyl methacrylate) incorporated with 1-ethyl-3-methylimidazolium bis(trifluorosulfonyl) imide ionic liquid electrolytes were prepared using solution casting technique. Interaction between the polymer and ionic liquid was confirmed by Fourier transform infrared spectroscopy. The presen…
In the present research work, an aluminum-based metal matrix composite with in situ Al4SiC4 particles has been developed by the incorporation of TiC particles in commercial aluminum melt through a stir-casting method. Microstructure evaluation in correlation to developed hardness and mechanical properties was performe…
Polymeric multicompartmental microparticles have significant potential in many applications due to the capability to hold various functions in discrete domains within a single particle. Despite recent progress in microfluidic techniques, simple and scalable fabrication methods for multicompartmental particles remain c…
We present a combination of experimental data and modeling that explains some of the important characteristics of black silicon (BSi) developed in cryogenic reactive ion etching (RIE) processes, including static properties (dependence of resulting topography on process parameters) and dynamic aspects (evolution of top…
Poly(3-hexylthiophene) (P3HT) is one of the most extensively investigated conjugated polymers and has been employed as the active material in many devices including field-effect transistors, organic photovoltaics and sensors. As a result, methods to further tune the properties of P3HT are desirable for specific applic…
A significant improvement in efficiency is achieved for porphyrin (YD2-o-C8) based dye-sensitized solar cells, coupled with [Co(bpy)3](3+/2+) mediator electrolyte. However, the poison of the counter electrode (CE) by the [Co(bpy)3](3+/2+) mediator remains a significant barrier to producing a reliable high-performance…
β amyloid peptide plays an important role in both the manifestation and progression of Alzheimer disease. It has a tendency to aggregate, forming low-molecular weight soluble oligomers, higher-molecular weight protofibrillar oligomers and insoluble fibrils. The relative importance of these single oligomeric-polymeric…
The purpose of this work was to study the role of cesium in sodium‐based geopolymer and its thermal stability for nuclear waste management. A series of mixed sodium and cesium geopolymer samples (Na 1− x Cs x ) 2 O·Al 2 O 3 ·SiO 2 ·12H 2 O (referred to as (Na 1− x C s x )‐ GP , where x = 0, 0.08, 0.15, 0.42, 1) have b…
Nanoscale contact mechanisms, such as friction, scratch, and wear, have a profound impact on physics of technologically important particulate systems. Determining the key underlying interparticle interactions that govern the properties of the particulate systems has been long an engineering challenge. Here, we focus o…
The variation in the high temperature thermodynamic properties of the Li-Sb system with temperature (425–775ºC) and composition ( x Li = 0.01–0.75) was determined by electromotive force (emf) measurements in a cell configured as follows: Li-Bi reference electrode ( x Bi = 0.35) | eutectic of LiCl-KCl or LiCl-LiF | Li-…
Ceramic composites found in nature, such as bone, nacre, and sponge spicule, often provide an effective resolution to a well‐known conflict between materials' strength and toughness. This arises, on the one hand, from their high ceramic content that ensures high strength of the material. On the other hand, various pat…
Protein kinases are involved in a variety of diseases including cancer, inflammation, and autoimmune disorders. Although the development of new kinase inhibitors is a major focus in pharmaceutical research, a large number of kinases remained so far unexplored in drug discovery projects. The selection and assessment of…
This work explores the dielectric and polarization properties of block copolymers and homopolymer blends containing a terthiophene-rich, electronically polarized block (PTTEMA) and an insulating polystyrene block (PS). PTTEMA-b-PS block copolymers were synthesized by reverse addition-fragmentation chain transfer (RAFT…
INTRODUCTION: GTP cyclohydrolase I (GTPCH) catalyses the first and rate-limiting reaction in the synthesis of the enzymatic cofactor, tetrahydrobiopterin (BH4). Loss of function mutations in the GCH1 gene lead to congenital neurological diseases such as DOPA-responsive dystonia and hyperphenylalaninemia. However, litt…
Photodegradation of inverted organic solar cells based on ZnO as an electron transport layer (ETL) was studied over short time scales of 5 min and 8 h. Devices with ZnO as ETL reproducibly exhibited a steep loss of open-circuit voltage, VOC, and shunt resistance, RSH, in a matter of minutes upon illumination. Removing…
Amyloid fibrils are ubiquitous proteinaceous aggregates occurring in vivo and in vitro, with an invariant structural fingerprint at the molecular length scale. However, interpretation of their mesoscopic architectures is complicated by diverse observable polymorphic states. We here present a constitutive model for amy…
Polynuclear Pt(II) complexes are a novel class of promising anticancer agents with potential clinical significance.
