We analyze the influence of strong electron-phonon coupling and thermal fluctuations on the Hall effect in organic crystals, using a variant of the Kubo formula. The Hall effect in organic crystals cannot simply be understood based on a band picture, but it is governed by competition between intermolecular quantum coh…
A reusable metallic substrate of surface-enhanced-Raman-scattering (SERS) was fabricated with field-enhancement property. Silver nanoparticles spread on a glass substrate and covered with a graded SiO2 coating were employed to enhance and to modulate the Raman scattering signal of probed samples. In the study, the Ram…

We achieved the electrical control of a magnetic state by using an external magnetic field via electric field-induced resistance (EIR) change phenomena. We prepared a La0.7Sr0.3MnO3 (LSMO) film which showed EIR changes. Before the EIR treatment, the sample barely showed negative magnetoresistance (MR). After the EIR t…
Goldkatalyse: Experimentell und theoretisch wurde bestätigt, dass die Grenzflächenatome eines Au/TiO2-Katalysators sowohl hoch reaktiv als auch hoch selektiv in der Oxidation von Methanol zu Formaldehyd mit O2 bei niedrigen Temperaturen sind. Der mikroskopische Mechanismus dieser komplexen Reaktion wurde im Detail auf…
Abstract The Johnson‐Cook parameters for the zirconium material were determined based on the data obtained from the tensile testing of zirconium specimens at different strain‐rates and different temperatures. The velocity difference (VPL) between the particulated jet fragments was calculated for zirconium liners of di…
This paper studies the influence of surface residual stress on the fracture of the double cantilever beam (DCB) specimens. The closed-form solutions of the energy release rate and the stress intensity factor are derived by using Timoshenko beam theory. Results show that positive residual surface stress and the root ef…
Put a ring on it: A cyclic azobenzene has a much higher melting point, stronger fluorescence, and better film-forming and SRG-formation ability than its linear precursor. Pcyclic-AzoMMA, with cyclic azobenzene pendant groups, has a much higher Tg value (100 °C) than Plinear-AzoMMA, with linear pendants groups (58 °C),…
In this study, octa(aminophenyl)silsesquioxane (OAPS), octakis(dimethylsiloxypropylglycidylether) silsesquioxane (OG) and phosphorous skeletal bis(4-maleimidophenyl)benzoxazine were synthesized and characterized. The polyhedral oligomeric silsesquioxane (POSS) derivative (OAPS and OG)-reinforced polybenzoxazine (PBZ)…
The extent of block microphase separation in nonfrustrated A–B–C triblock copolymers forming a “three-domain, four-layer” lamellar morphology is examined. Specifically, the extent of separation between the B and C blocks is probed, for the case where the B and C blocks are sufficiently compatible that they would not b…
Abstract The process of rubber composite armor anti‐shaped charge jet (SCJ) penetration was divided into four parts based on jet deformation that occurred when the SCJ penetrated the rubber composite armor. Results on the interference speed interval, interference frequency, and surplus penetration capability of the SC…
The size dependence of yield point assisted ferroelastic switching is dominated by the appearance of a minimum size where the domain switching by external strain is swamped by noise which is determined by internal jamming processes. The lower ferroelastic lateral cut-off size was found in computer simulations to be 20…
Abstract The reactivity of a furan entrapped in a macrocycle leads to the formation of an [18]triphyrin(4.1.1) structure. Oxidative transformation of the final molecule gives two rigid lactams presenting structural factors of optically active compounds.
Abstract The reaction of H2C(PCl2)2 with four equivalents of iPrMgCl produces H2C(PiPr2)2, which was treated with tellurium in boiling toluene, or selenium in toluene at room temperature, to give the monochalcogenides EPiPr2CH2PiPr2 (E = Te, 4a; E = Se, 4b) in high yields. X‐ray structural determinations show that 4a…
Silica nanoparticles functionalized with amine groups and in the size range of approximately 60-94 nm were produced by combining sol-gel processing and emulsion technology. Hexa-aza cage ligand SarAr-NCS was conjugated to the silica nanoparticles and subsequently radiolabeled with a solution of (57)Co(2+)-doped carrie…
The tetranuclear [{Pt(CNC)(tht)}3Tl](PF6) (tht = tetrahydrothiophene; SC4H8; CNC = C,N,C-2,6-NC5H3(C6H4-2)2; 2) cluster has been prepared by the reaction of [Pt(CNC)(tht)] (1) and TlPF6 (molar ratio 3:1) and structurally characterized. The Tl(I) atom is bonded to three Pt(II) centers bearing a perfect trigonal coordin…
Thin films of titanium oxide TiO 2 have been grown on Fe(001) substrates by means of reactive deposition at different temperatures. X-ray photoemission spectroscopy and low-energy electron diffraction have been employed to investigate the electronic and structural properties of the TiO 2 /Fe interfaces. We observe tha…
We investigate the high‐temperature compressive deformation behavior of a novel, fully dense and structurally uniform, 20 vol% multiwalled carbon nanotube ( MWCNT )–α‐ Al 2 O 3 matrix hybrid, which has a strong room‐temperature interfacial shear resistance ( ISR ) and a unique MWCNT ‐concentrated grain‐boundary ( GB )…
The effect of transition metals as a promoter of physico-mechanical properties of radiation-vulcanized natural rubber latex (RVNRL) films was investigated. RVNRL films were prepared by the addition of transition metals (Fe, Mn, etc.) of different concentrations (0–30 ppm) in natural rubber (NR) latex and irradiated wi…
