We investigate multicompartment micelles consisting of poly(2-oxazoline)-based triblock copolymers for nanoreactor applications, using the DPD simulation method to characterize the internal structure of the micelles and the distribution of reactant. The DPD simulation parameters are determined from the Flory-Huggins i…
The results of the investigation of the optical properties and calculations of the density of states N(E) of the Heusler alloys Co2Cr1–x Fe x Al (x = 0, 0.4, 0.6, 1.0) have been presented. It has been found that the band spectrum substantially changes, especially in the vicinity of the Fermi level, due to the concentr…
We have explored the dehydrogenation of methoxy on pristine and defective (111), (100), and (110) ceria surfaces with density functional methods. Methanol conversion is used as a probe reaction to understand structure sensitivity of the oxide catalysis. Differences in reaction selectivity have been observed experiment…
Towards the Determination of the Origin of Sulfur Compounds in Marine Zones by Means of the Chloride/Sulfate Ratio: Applications in Atmospheric Corrosion Studies, Echeverría, M., Abreu, C. M., González, A., Ortega, A., Echeverría, C. A.
The exploitation of colloidal building blocks with morphological and functional anisotropy facilitates the generation of complex structures with unique properties, which are not exhibited by isotropic particle assemblies. Herein, we demonstrate an easy and scalable bottom-up approach for the programmed assembly of hai…
In this paper, a new and efficient SPICE model of flexible transition metal dichalcogenide field-effect transistors (TMDFETs) is developed for different types of materials, considering effects when scaling the transistor size down to the 16-nm technology node. Extensive circuit-level simulations are performed using th…
Preparation of Au@Ag NPs at a gas/liquid interface by a seed-mediated growth procedure and their application for sensitive detection of hydrogen peroxide.
Tri- and tetranuclear Ru <sup>II</sup> –GdII2 and Ru <sup>II</sup> –GdIII3 d–f heterometallic complexes, which function as contrast agents for MRI and as optical probes for fluorescence imaging, are reported. <italic>In vitro</italic> studies using the HeLa cell lines show that these complexes exhibit anticancer activ…
Detailed steady-state and time-resolved fluorescence quenching measurements give deep insight into ion transport through nanometer thick diblock copolymer membranes, which were assembled as biocompatible shell material around CdSe/CdS quantum dot in quantum rods. We discuss the role of polymer chain length, intermolec…
Mg-20.5 at% Sc alloy with hcp (α)+bcc (β) two-phase alloy was investigated to understand the effects of aging treatment at 200℃ on microstructure, hardness and tensile properties. The Mg-Sc alloy ingot was prepared by induction melting in Ar atmosphere, and then hot rolled at 600℃ followed by cold rolling into a sheet…
T10 steel slid against 20CrMnTi steel on a pin-on-disc wear test rig. Optical Microscope (OM), scanning electron microscope (SEM), and High Resolution Transmission Electron Microscope (HRTEM) methods were used to analyze the microstructures in the worn surface layers. The microstructures in the worn surface layers of…
A hierarchical structure of one-dimensional CeO <sub>2</sub> /SnO <sub>2</sub> core–shell nanowires on a three-dimensional porous disk (namely the “nanowire forest”) could maximize the reaction surface area and avoid coarsening during hydrogen generation.
Size and shape tuneable ZnO nanostructures were prepared by a low frequency ultrasound (42 kHz) route using various organic solvents as the reaction media.
Furfural is an important chemical solvent and intermediate. Sensitive detection of this compound has attracted great interest in various fields. Surface-enhanced Raman spectroscopy (SERS) is a highly sensitive method for material detection because of its optical enhancement effect of plasmonic nanostructures. This stu…
Herein we describe the synthesis, structure and electronic properties of an unusual redox-active ditopic ligand with a stable open-shell configuration. This stable phenoxyl radical features intense and very low energy electronic transitions in the near infrared (NIR) part of the spectrum and is structurally set up to…

Polycrystalline piezoelectric lead-free Bi0.5Na0.5TiO3 (abbreviated as BNT) thin films were deposited on Pt/TiO2/SiO2/Si substrates by an optimized Sol-Gel process. The phase structure and morphology of the as-prepared product were examined by X-ray diffraction (XRD), Raman spectroscopy and scanning electron microscop…
We describe herein that the self-assembled nanoobjects based on pyrimidinylene-phenylene macrocycles, 1 and 2, which possess the capability to respond to acid-stimuli by proton binding, can undergo reversible transformation of self-assemblies and fluorescence switching by protonation-deprotonation.
We investigate several structural properties of low-molecular weight AB diblock copolymer melts, focusing on a number of features that substantially deviate from those of high-molecular weight copolymer melts. The study is based on the wormlike chain formalism aided by random phase approximation and self-consistent fi…
Porphyrins and their structural analogs have drawn continuous attention owing to their physico-chemical properties associated with biological, medical and material chemistry. Consequently, many structural modifications of the porphyrin skeleton have been reported as a fundamental tool for tuning the physico-chemical p…
