Abstract Supramolecular hybrid functional nanoparticles (NPs) can be obtained via the colloidal tectonics approach provided that multiple interactive molecular tectons are used. Herein, the programmable synthesis of novel hybrid core–shell nanoparticles via the following sequential steps is reported: (i) complexation…
An amorphous aluminium-oxide supercapacitor can store a large amount of electric charge on its blackish, uneven Al 2 O 3− x surface, which has a convexity of 21 nm, AlO 6 clusters, and a resistivity of . The electric storage can be elucidated by extremely enhanced electron trapping resulting from both the quantum-size…
ABSTRACT Polycarbonates (PCs) are commonly used as a blend and a composite to achieve pecuniary advantages and dimensional stability. While the toughness of a homogeneous PC matrix has been extensively investigated, examination for the toughness of heterogeneous blend systems such as PC/polypropylene (PP) blends has b…
The presence of the valley degree of freedom in graphene leads to the valleytronics, in which information is encoded by the valley quantum number of the electron. We propose a valley controlled spin-transfer torque (STT) in graphene-based normal/normal/ferromagnetic junctions with the normal lead irradiated by the off…
Abstract Many natural materials have helical or twisting shapes. Herein, we show the formation of helical fibers with the lengths of micrometers by the evaporation‐driven self‐assembly on silicon wafers of functionalized cellulose nanowhiskers (CNWs) with surface‐attached acyl chains. The self‐assembly process and the…
Nanoparticles can be used as a smart drug delivery system, when they release the drug only upon degradation by specific enzymes. A method to create such responsive materials is the formation of hydrogel nanoparticles, which have enzymatically degradable crosslinkers. Such hydrogel nanoparticles were prepared by ionotr…
Abstract A multiscale simulation framework for polycondensation and other types of polymerization mechanisms, which is used to study the hyperbranched polymerization of AB 2 type monomer 4,4‐bis‐(4'‐hydroxyphenyl)pentanoic acid is presented. The reaction framework is established by combining the coarse‐grained molecul…
This article presents a facile synthesis of cadmium sulfide nanorods (CdS-NR) and nanospheres (CdS-NS) using cadmium(II) dithiocarbamate as a precursor in the presence of two different thermalizing solvents {ethylenediamine (en) and octylamine (OA)}. The as-synthesized CdS-NR and CdS-NS were characterized by powder X-…
ABSTRACT In this article, a novel process called cylindrical‐electrode‐assisted solution blowing spinning (CSBS) for producing excellent quality nanofibers with simultaneous electrostatic force and air stretching is reported. The originality of this work is in a new apparatus. With a cylindrical electrode, the solutio…
Hot extruded (EX) AZ61 magnesium alloy was processed by the twist channel angular pressing (TCAP) method, which combines equal channel angular pressing (ECAP) and twist extrusion (TE) processes and significantly improves the efficiency of the grain refinement process. Both the initial hot extruded AZ61 alloy and the a…
Abstract At organic semiconductor interfaces, an electron and a hole can be bound Coulombically to form an interfacial charge transfer (CT) exciton. It is still under debate how a CT exciton can overcome its strong binding and dissociate into free carriers. Experimentally, capturing the evolution of the CT exciton on…

ABSTRACT The objective of the present study was to prepare poly(lactic acid) (PLA) porous microspheres. Special attention was paid to the effects of improving the surface hydrophilicity of the microspheres on the adsorption of silver ions. The linear PLA and the three‐branched‐chain PLA microspheres with pores or with…
In this study, we investigated the viscoelastic properties of metal nanoparticle monolayers at the air/water interface by dilational rheology under periodic oscillation of surface area. Au nanoparticles capped with oleylamine form a stable, dense monolayer on a Langmuir film balance. The stress response function of a…
Deuterium permeation through a fusion-relevant ferritic steel F82H with and without erbium oxide coatings under γ-ray irradiation has been investigated in a temperature range from 300 to 700 °C. The deuterium permeation flux through F82H sample increased by γ-ray irradiation at lower temperatures below 450 °C. The irr…
The effects of temperature and carrier density on the self-energy of electrons in semiconductor carbon nanotubes (CNTs) are theoretically studied by using the Matsubara Green’s function approach. We show that the bandgap is slightly changed whereas the electron effective mass is strongly affected by the temperature an…
Abstract To date, the piling up of successive photons of low energies (near infrared; NIR) using a single lanthanide center and linear optics to ultimately produce upconverted visible emission was restricted to low‐phonon solid materials and nanoparticles. Now we show that the tight helical wrapping of three terdentat…
In this study, the results of measurement for DC flashover characteristics of silicon rubber insulators in the presence of surface charges and in terms of geometric characteristics have been examined and analysed. In the carried out experimental tests, the surface of different insulators was charged by an external cor…
ABSTRACT Poly(propylene glycol) (PPG)‐based nanocomposites have been prepared one shot using various contents of functionalized SiO 2 nanoparticle as filler‐crosslinker agent. Triethoxy silyl propane‐1‐amine has been used as coupling agent for functionalization of SiO 2 nanoparticle to improve its reactivity. The resu…
ABSTRACT Bilayer films propose to combine the characteristics of different individual polymer sources in a single structure, aiming to improve the properties of the films obtained. The objective of this study was to develop and characterize bilayer films prepared from individual films of zein, wheat gluten, and protei…
