Y. Wang, L. M. Liz-Marzán, and co-workers show a 3D visualization of electron tomography measurements made on gold nanoparticles formed by seeded growth on gold nanostars, capped with a mixture of dithiols and cationic surfactants. On page 4314, this particular surface chemistry directs gold shell growth into unusual…
Abstract The catalyst is robust, recoverable, and recyclable without significant loss of its activity.
Theoretical and modelling concepts in semiconductor defect chemistry and electrochemistry have hugely evolved over the last years and are crucial for their respective fields such as optoelectronics and semiconductor devices or corrosion and battery materials. Recently, we developed an approach which is based on a full…
A wide range of peptides and proteins has the unique propensity to self-assemble into insoluble fibrillar quaternary structure enriched in intermolecularly hydrogen bonded β-sheets [1,2]. The accumulation of these highly ordered aggregates in human tissues is associated with a number of devastating disorders, such as…
A new polyoxomolybdate complex with chemical formula [NH 2 (CH 3 ) 2 ] 4 [Mo 8 O 26 ] ( I ) has been synthesized and structurally characterized. Single-crystal X-ray analysis of compound I reveals that the ammonium cation generates an intricate 2D supramolecular architecture (CIF file CCDC no. 1026577). The detail ana…
Currently the problem of spent nuclear fuel (SNF) reprocessing is relevant and studied in many countries. Existing methods of radiochemical reprocessing can not fully meet all the economic, energy and environmental needs of humanity [1]. Recently, the physical principles of magnetoplasma (MP) method of SNF separation…
A novel mesomorphic series is RS-C6H4-COO-C6H4-CO-CH=CH-C6H4-OC18H37(n) (para) of chalconyl ester play double role thermotropic as well as lyotropically bioactive is synthesized and studied with a view to understand and establish the effect on mesomorphism when changing on left thioalkyl chain.the relation between mes…
Abstract In this work, we present the impact of S/D contact formation, that is, by SiN plasma doping (hydrogen incorporation), metallic reduction (by calcium) and by argon plasma (compositional change) on NBIS instabilities of self‐aligned a‐IGZO TFTs.
Abstract In this article, a polymer stabilized ferroelectric liquid crystal (FLC) is introduced. With the expose of UV light, the doped monomer formed a polymer network and thus stabilize the FLC working in electrically suppressed helix electric‐optical mode. Therefore, we are able to achieve a high contrast ratio, fa…
This research was conducted to investigate the effect of modification with maleic anhydride and methyl methacrylate on mechanical properties and decay resistance of poplar wood. Samples of mechanical and biological resistance tests were prepared according to ASTM D143-94 and EN113 standards. Treatment levels were divi…
Abstract In this paper, we report that IZO/Ag/IZO multilayer could be used as reflective electrode for top emitting OLED. A further investigation on top emitting OLED with cohost EML demonstrates better charge injection and improve efficiency. The device showed a maximum current efficiency of 130 cd/A, a maximum power…
Composite materials based on dielectrics with metal inclusions are of a great interest for nanoplasmonics, photonics and nonlinear optics. They are also prospective as bio-optical sensors which can amplify weak signals from single molecules. Raman scattering of single molecules placed on metal-dielectric substrate is…
Abstract Mit ultrakalten atomaren Gasen lässt sich das Verhalten von Elektronen in Festkörpern simulieren – in extremer Zeitlupe und in tausendfacher Vergrößerung. Elektronen sind Fermionen, Teilchen mit halbzahligem Eigendrehimpuls (Spin), man benötigt also fermionische Atome. Nun wurde ein Mikroskop für atomare Ferm…
Se estudió la resistencia al desgaste adhesivo de recubrimientos de bronce al aluminio depositados con la técnica de proyección térmica por llama sobre bronce fosforado SAE 62. Los recubrimientos fueron fabricados variando las presiones parciales de los gases de combustión, oxígeno y acetileno. El material utilizado f…
The JWST IEC conformal shields are mounted onto a composite frame structure that must undergo qualification testing to satisfy mission assurance requirements. The composite frame segments are bonded together at the joints using epoxy, EA 9394. The development of a test method to verify the integrity of the bonded stru…
Abstract In this article, we disclose an ESHFLC display that is characterized by the out‐standing optical quality with contrast 10k: 1, response time 10 μs, wide viewing angle, and low driving voltages. Thus, the proposed ESHFLC displays, with simpler fabrication procedure, have great potential and cloud offer better…
We propose a new method for the determination of the rotation measure (RM) for pulse sources in the decameter wavelength range. This method allows us to define RM with accuracy up to 10−4[1–3], which had never been achieved in any known methods. The method is effective in the consideration of individual pulses, and al…
Numerous experimental studies of hydrogen storage alloys (materials that can reversibly absorb significant amounts of hydrogen) in order to optimize their properties are mainly connected with modification of their component composition. However, a number of aspects, in particular, the role of surfaces of these materia…
Abstract : We present the results of development and comprehensive characterization of fully densified erbium (Er3+): magnesium oxide (MgO) and neodymium (Nd3+):MgO transparent ceramics fabricated from specially formulated nanopowders. The results are presented with major emphasis on potential laser application and th…
Abstract We present the 3D moiré techniques. Practically most important of them are the minimization of the moiré effect in the autostereoscopic 3D displays and the 3D moiré displays. Other related issues are also discussed.
