Abstract The main obstacles to building better supercapacitors are still trade-offs between energy and power parameters. To promote commercial supercapacitor behaviors, proper optimization toward electrode configurations/architectures may be a feasible and effective way. We herein propose a smart and reliable electrod…
In this paper, we investigate the properties of aggregation transitions in the context of generic coarse-grained homopolymer systems. By means of parallel replica-exchange Monte Carlo methods, we perform extensive simulations of systems consisting of up to 20 individual oligomer chains with five monomers each. Using t…

Abstract Conductive Ga 2 O 3 thin films with an In 2 O 3 buffer layer have been prepared on c -plane sapphire substrates using a laser molecular beam epitaxy technique. The effects of the In 2 O 3 buffer layer on the structure and optical, electrical and surface state properties of the Ga 2 O 3 films have been studied…
We investigated the deposition and the phase-change properties of In-doped GeTe thin films obtained by plasma enhanced metalorganic chemical vapor deposition and doped with indium using a solid delivery system. The sublimated indium precursor flow rate was calculated as a function of sublimation and deposition paramet…
Biominerals are directed by macromolecules, especially proteins, and incorporate organic occlusions contributing to their overall mechanical properties. However, their distribution patterns in biominerals at the microscale are unclear. Here, we labeled nacre proteins of the pearl oyster Pinctada fucata with cyanine 5…
We show that a cylindrical lensing system composed of two metasurfaces with suitably tailored non-Hermitian (i.e., with distributed gain and loss) and nonlocal (i.e., spatially dispersive) properties can perform magnified imaging with reduced aberrations. More specifically, we analytically derive the idealized surface…
Motivated by recent transmission electron microscopy (TEM) experiments on α-Ag 2 WO 4, the coalescence process of Ag nanoparticles (NPs) is investigated using molecular dynamics (MD) simulations. These Ag NPs are formed by irradiation of α-Ag 2 WO 4 crystals by electrons from a TEM gun. This behavior can be considered…
Abstract The redox reaction between KMnO 4 and Ni was carried out on a chain‐like Ni surface under hydrothermal conditions and γ‐MnO 2 nanosheets were produced through this facile route. The original Ni nanochains, as cores, dominated the final morphology of the composites with MnO 2 nanosheets loaded on their surface…
In this paper, we demonstrate the stabilization of polystyrene microspheres by encapsulating them with dumbbell-shaped colloids with a sticky and a nonsticky lobe. Upon adding a depletant, an effective short ranged attraction is induced between the microspheres and the smaller, smooth lobes of the dumbbells, making th…
Abstract A facile method was developed for chemical vapor deposition (CVD) growth of large-scale vertically oriented molybdenum disulfide nanoflakes on a basal MoS 2 thin film ( v -MoS 2 on MoS 2 -TF) utilizing a porphyrin-type organic promoter layer, which catalyzed the synthesis and allowed large scale growth of v-…
Under atmospheric pressure, the solubilities of adipic acid, glutaric acid, and succinic acid in acetic acid + cyclohexanone mixtures were measured respectively by using the laser dynamic method in which the temperature ranged from 298.55 to 340.85 K and the mass fraction of cyclohexanone in the binary solvent mixture…
Stainless steel (SS) coronary stents continue to present risk of in‐stent restenosis that impact its long term safety and efficacy. The present work focuses on developing a drug‐free and polymer‐less surface on coronary stents by utilizing a titania (TiO 2 ) nanotexturing approach through hydrothermal processing, that…
Abstract Layered (Bi 1−x In x ) 2 Te 3 -In 2 Te 3 (x = 0.075) composites of pronounced anisotropy in structure and thermoelectric properties were produced by zone melting and subsequent coherent precipitation of In 2 Te 3 from a (Bi 1−x In x ) 2 Te 3 (x > 0.075) matrix. Employing solid state phase transformation, t…
Abstract We report the characteristics of an n-ZnO/p-Si membrane heterojunction flexible photodetector sensitive to UV and visible illumination. A piezo-phototronic effect has been observed for the deposited ZnO thin films on flexible silicon membranes. Si membranes as low as ~3.0 µ m thick have been fabricated by the…
Nonstoichiometry lead-free 0.94Na x Bi y TiO3–0.06Ba z TiO3 (N x B y T–0.06B z T) (from x = y = 0.5, z = 1.00 to x = 0.5, y = 0.534, z = 1.02) ceramic compositions were prepared by a conventional solid-state route. XRD shows that the compositions are at a morphotropic phase boundary where rhombohedral and tetragonal p…
Denisovite is a rare mineral occurring as aggregates of fibres typically 200–500 nm diameter. It was confirmed as a new mineral in 1984, but important facts about its chemical formula, lattice parameters, symmetry and structure have remained incompletely known since then. Recently obtained results from studies using m…
We herein report the synthesis, UV–vis absorption, fluorescence emission, and redox properties of three novel meso- diphenylbacteriochlorins. Significantly, we show that substituents at the meso-positions of an air-stable bacteriochlorin can be manipulated for the first time. With proper design, this allows tailor-mad…
In this work, we successfully synthesized aluminum-doped polyaniline in various solvent media using chemical oxidation polymerization, and for the first time, investigated their applications as counter electrode (CE) in dye-sensitized solar cells (DSSCs). The experimental results (field emission scanning electron micr…
Die Osteosynthese mit kopflosen Kompressionsschrauben ist für instabile Kahnbeinfrakturen etabliert. Die derzeit üblichen Schrauben aus Titanlegierungen oder Stahl verbleiben in situ. Aufgrund der Dichte und ihrer ferromagnetischen Eigenschaften sind sie z.B. bei der Kernspintomografie Ursache von Artefakten in der po…
