Based on first-principles density functional calculations we propose a novel Al vacancy induced ferromagnetism occurring at the LaAlO(3) surface of SrTiO(3)/LaAlO(3) bilayers. Magnetism at cation vacancies away from the surface is quenched due to charge compensation. Magnetic surface Al vacancies are stabilized due to…
The hydrogen desorption properties of the LiNH 2 –LiH system were dramatically improved by the addition of 5 mol% KOH.
A lyotropic chromonic liquid crystal (LCLC) is an orientationally ordered system made by self-assembled aggregates of charged organic molecules in water, bound by weak noncovalent attractive forces and stabilized by electrostatic repulsions. We determine how the ionic content of the LCLC, namely, the presence of mono-…
Here we will discuss the underlying principles of heat transfer. Although heat is most oen discussed from a macroscale perspective, we are going to zoom in all the way to the nanoscale to see the stu that heat is actually made of. We will also discuss how the physics of heat and energy vary at the nanoscale. To do so,…
Ammonia can assume a Zn site in ZnO forming an isovalent substitutional defect, which can become an acceptor by capturing an interstitial H atom.
ABSTRACT In this work, ball milling is evaluated as a methodology to develop polylactide (PLA)‐bacterial cellulose nanocrystals (BCNC) nanocomposites. This technique, widely used for clay‐based nanocomposites, is effective in breaking up to a very large extent the freeze‐dried nanocellulose aggregates, giving raise to…
A combined study of experimental and molecular dynamics (MD) simulation methods is presented for hindered phenol AO‐80/nitrile‐butadiene rubber/poly(vinyl chloride) (AO‐80/NBR/PVC) composites with different AO‐80 contents to establish the microstructure‐damping property relations. MD simulation found that the AO‐80/NB…
The chemistry of the process and coolant systems in water-cooled nuclear reactors is tightly controlled to minimise material degradation and, for some systems, to regulate reactor power. Tight cont...
Abstract The motion of gravity-driven deformable drops (Bond number, $\mathit{Bo}\sim 0.8{-}11$ ) through a circular confining orifice (ratio of orifice diameter to drop diameter, $d/D<1$ ) was studied using high-speed imaging. Drops of water/glycerin, surrounded by silicone oil, fall toward and encounter the orifice…
Here we describe for the first time the synthesis of colloidally stable, brightly luminescent perfluorodecyl-capped silicon nanocrystals and compare the properties of solutions and films made from them with those of their perhydrodecyl-capped relatives. The perfluorodecyl capping group compared to the perhydrodecyl ca…
A self-powered photodetector was fabricated by taking advantage of the band bending at the ZnO/electrolyte interface. And a 48% performance enhancement was achieved with the introduction of 0.15% compressive strain due to the generation of piezopolarization charges. This result could be extended to other solid-liquid…
The magnetic penetration depth $(\ensuremath{\lambda})$ as a function of applied magnetic field and temperature in ${\mathrm{SrPt}}_{3}\mathrm{P}$ (${T}_{c}\ensuremath{\simeq}8.4$ K) was studied by means of muon-spin rotation $(\ensuremath{\mu}\mathrm{SR})$. The dependence of ${\ensuremath{\lambda}}^{\ensuremath{-}2}$…

From first-principles methods, the spin-dependent electronic properties of zigzag-edged graphene nanoribbons (ZGNRs) with a line defect (558-defect) are investigated systematically and compared to those of the pristine ZGNR. Results show that the line defect possesses an obvious tuning effect on the spin-polarization…
Abstract Mn3O4 nanomaterials with different morphologies (sphere, nanowire, and octahedron) embedded into functionalized nanoporous polymers were developed by a facile one‐pot solvothermal technique at different temperatures. These Mn3O4‐based hybrid materials could behave as heterogeneous nanocatalysts to perform sp3…
An improved rectangular cavity (RC) approach is proposed for the accurate complex permeability determination of materials in the microwave frequency band. The proposed approach assumes the bar-shaped magnetic specimen to be placed along the width of the cavity to increase the sensitivity of the measurement. A generali…
Three-chromophore systems with light-harvesting behavior were prepared, which are based on periodic mesoporous organosilica (PMO) with crystal-like ordered structure. The organic bridges of biphenyl-PMO in the pore walls act as donors and two types of dye are incorporated in the one-dimensional channels. Consecutive t…
Dipole emitters used in nano optics and nanophotonics (e.g., fluorescent molecules or quantum dots) are weak radiators and thus detecting the radiation of a single emitter gets possible only if it is significantly enhanced. For this enhancement, one often utilizes resonant nanoantennas (Purcell's effect); this method,…
Abstract The complex pathway of transmitted stress and strain within elastic networks affects the conformations of single network chains in a complex and inhomogeneous manner. For a novel experimental assessment, we investigated moderately to highly cross-linked vulcanized natural rubber networks with proton multiple-…
New types of linear tetranuclear Ln(III)-Ni(II)-Ni(II)-Ln(III) (Ln(III) = Dy (1), Gd (2)) complexes have been prepared using the multidentate ligand N,N'-bis(3-methoxysalicylidene)-1,3-diaminobenzene, which has two sets of NO and OO' coordination pockets that are able to selectively accommodate Ni(II) and Ln(III) ions…
