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…

The transport properties of F-doped boron nitride nanotube (BNNT) top-gate field effect devices were investigated to demonstrate the realization of p-type BNNTs by F-doping. The drain current was found to increase substantially with the applied negative gate voltage, suggesting these devices persist significant field…
Preparation of LuFe 2 O 4 ceramics under vacuum environment was investigated together with the structural, dielectric, and magnetic characterization. Single‐phase LuFe 2 O 4 could be obtained by the present process and the crystal structure was identified to be rhombohedral in space group . An obvious dielectric relax…
Investigating the effects of local scattering mechanisms is of great importance to understand charge transport in semiconductors. This article reports measurements of the hole transport properties of boron-doped (100) single-crystalline chemical vapor deposited diamond. A Time-of-Flight measurement using a 213 nm, pul…
Infrared spectra of hydrogenated diamond nanocrystals of one nanometer length are calculated by ab initio methods. Positions of atoms are optimized via density functional theory at the level of the generalized gradient approximation of Perdew, Burke and Ernzerhof (PBE) using 3-21G basis states. The frequencies in the…
We use multi-photon photoemission electron microscopy (PEEM) to image the enhanced electric fields of silver nanoparticles supported on a silver thin film substrate. Electromagnetic field enhancement is measured by comparing the photoelectron yield of the nanoparticles with respect to the photoelectron yield of the su…
This paper exploits the physical investigation on liquid crystal complexes obtained by self-organisation of p-n-alkyl benzoic acid (nBA) mesogens with non-mesogenic materials heptyl p-hydroxy benzoate (7HB). Intermolecular interactions of the molecules result the hydrogen bond between the proton donor (COOH) of nBA an…

The intercalation process of Li underneath a graphene layer grown on a Cu foil has been studied by means of synchrotron radiation photoemission spectroscopy and X-ray photoelectron spectroscopy. The deposition of Li on the graphene surface at room temperature results in a charge transfer from the adsorbed Li atoms to…
From blinking surface-enhanced Raman scattering (SERS) of anionic thiacyanine adsorbed on single Ag nanoaggregates, the electromagnetic field and the molecular behavior in a nonemissive state were investigated by a truncated power law analysis. The power law that reproduces probability distribution of dark SERS events…
Soluble covalent organic nanoframeworks up to generation 2.5 (G2.5) are synthesized with self-similar H-shaped conformations by using a bottom-up approach including iterative C-H bond functionalization. The electrical characteristics of nanoscale thin-film semiconductors of the conjugation-interrupted frameworks can b…
Background: One of the most important causes of complications and mortality in medical centers are nosocomial infections. Disinfection of hospital surfaces is essential element for ensuring that infectious agents are not transmitted to patients. Alcohol-based and chlorine-based disinfectants have unfavorable propertie…
The electronic band structures and dielectric functions of (1−x)PbSc1/2Ta1/2O3−xPbHfO3 ceramics with different composition have been investigated by variable-temperature spectroscopic ellipsometry. Using the standard critical-point (SCP) model, three typical interband transitions can be observed from the second deriva…
