Transverse-geometry x-ray magnetic circular dichroism (TXMCD) measurements on Au/Co-staircase/Au(001) reveal the orbital origin of intrinsic in-plane magnetic anisotropy A gigantic TXMCD was successfully observed at the Co L 3,2 edges for Co thickness ( t C 0 ) in the 2-monolayer regime. A TXMCD-sum-rule analysis show…
Strain measurements are essential in structural health monitoring. Traditional strain gages require physical contact between the sensor and read-out device, perturb the surface being monitored, and allow measurement only at the specific location and orientation axis of the sensor. We demonstrate a novel non-contact, m…
Absolute cross sections for electron-impact ionization of W q + ions ( q ≤ 17) are measured using a well established electron-ion crossed beams technique. A special problem with many-electron tungsten ions is the existence of large numbers of long-lived excited states and their presence in the primary ion beams employ…
Porphycenes, structural isomers of porphyrins, usually exhibit strong fluorescence in organic solvents. However, in water they are practically insoluble or form only weakly emitting aggregates. We show that embedding porphycenes inside pluronic micelles in water solutions leads to the recovery of strong monomeric fluo…
We theoretically study the efficiency and angular distribution of a graphene-plasmon excitation by an electron beam. An electron beam incident on doped graphene induces the out-of-plane transition radiation and in-plane plasmon–polariton waves. At the same time the electron loses its kinetic energy by energy conservat…
The effects of microwave calcination (MC) and conventional muffle furnace calcination (CC) on the microstructure and magnetic properties of M‐type hexagonal ferrite Ca 0.15 La 0.39 Sr 0.46 Fe 11.7 Co 0.3 O 19 were investigated. The phase composition, microstructure, and magnetic properties of calcined materials were e…
ABSTRACT Microcontact printing has emerged as one of the most straightforward methods of surface patterning and has been successfully employed to obtain biologically instructive substrates for a wide range of tissue engineering applications. However, although a consolidated success has been gained in the patterning of…
The MCM-41 mesoporous molecular sieves have attracted a great deal of interest due to their application in adsorption processes, like in the removal of naphthenic acids, which are directly responsible for acidity and corrosiveness of petroleum. The objective of this work is to explore the synthesis, characterization,…
In order to improve the interconnection of TiO 2 photoelectrode for the flexible dye-sensitized solar cells (DSSCs) with plastic substrates, thin TiO 2 layers are additionally introduced to the surface of main TiO 2 nanoparticles by atomic layer deposition (ALD) at low temperature. The ALD-induced TiO 2 thin layers on…
Y 2 O 3 :Er,Yb upconversion nanoparticles were prepared by laser ablation in liquid and capped with poly(ethylene glycol) (PEG). A Nd:YAG green laser with nanosecond pulse duration was used. Capping was carried out by a two-step process. The first step is surface modification using a silane coupling agent, (3-aminopro…
We present some recent results dealing with resonant inelastic X-ray scattering (RIXS) on atomic targets in the 3-5 keV enegy region. In this so-called tender spectral region, the K-shell fluorescence branching ratios become reasonably large, but a full vacuum enclosure is still preferable to avoid detection efficienc…
We propose a novel method to generate vector beams in planar photonic crystal cavities with multiple missing-hole defects. Simulating the resonant modes in the cavities, we observe that the optical fields in each defect have different phase and polarization state distributions, which promise the compositions of vector…
Manganese phosphate coatings are widely used as pretreatment for corrosion and wear resistance of numerous automotive components. Manganese phosphating formulations are established with various additives to improve the coating weight besides achieving the required amount of iron dissolution in a shorter time. The aim…
Electron emission provides an excellent opportunity to probe the electronic structure and the chemical reactivity of materials. For molecules, the most natural way is describing it in the molecular frame. Recently, using the upgraded version of the EPICEA coincidence setup available at PLEIADES beamline at SOLEIL (Fra…
Cu 2 GeSe 3 (CGSe) was synthesized by mixing elemental powders and post-heating at 600 °C in N 2 gas. The X-ray diffraction pattern of the synthesized CGSe agreed with that of the simulated monoclinic structure. Characteristic diffraction peaks of 110 and 021 for the monoclinic structure were clearly observed. CGSe's…
We report current constructing states of the Ultra Slow Muon Beam at U-line / MUSE / J-PARC, which are supported by thermal muonium (Mu, μ + e − ) production with the most intense pulsed slow muon beam, laser resonant ionization, and transportation of Ultra Slow Muon Beam. A thermal Mu is produced by a hot tungsten fo…
In the past few decades, research has shown diadenosine polyphosphates (Ap n A) to be a family of intercellular and intracellular signaling molecules that play a key role in biological and pharmacological activities. ToF‐SIMS, recently shown to be a promising technique to analyze metabolites in biological samples due…
The diameter-dependent luminescence properties for individual ZnO wires were systematically investigated by means of a spatially resolved spectroscopic technique. The two-dimensional photoluminescence (PL) mapping image was presented to show the integrated optical emission properties at each position of the wire. A bl…
ABSTRACT Polypropylene (PP) composites that contain poly(aniline) (PANI) and ammonium polyphosphate crystalline form II (APP‐II) have both antistatic and flame‐retardant properties. In the present study, double anti‐functional PANI was prepared via in situ polymerization in the presence of APP‐II. Analysis of the Four…
Over the last few decades, carbon nanotube (CNT)-based thin films or nanocomposites have been widely investigated as a multifunctional material. The proposed applications extend beyond sensing, ultra-strong coatings, biomedical grafts, and energy harvesting, among others. In particular, thin films characterized by a p…
