Lanthanide-binding tags (LBTs) are small, genetically encoded, versatile protein fusion partners that selectively bind lanthanide ions with high affinity. The LBT motif features a strategically positioned tryptophan residue that sensitizes Tb3+ luminescence upon excitation at 280 nm. Herein, we describe the preparatio…
This study presents the potential of quantum dots as two-photon sensitizers for attached energy acceptors. With two-photon absorption cross sections, which are orders of magnitudes higher than those of any molecule, quantum dots constitute outstanding NIR sensitizers. The successful energy transfer to conjugated phtha…
We report a systematic investigation on the structural and magnetic properties of molecular-beam epitaxial growth of CrTe thin films with different layer thicknesses and Cr∕Te flux ratios. A phase diagram of the growth parameters is established based on the detailed analyses of the reflection high-energy electron diff…
Abstract The influence of polymer matrix molecular weight and filler particle size on rheological properties and extrudate distortions of metallocene polyethylene (mPE)/wood flour (WF) composites has been investigated by rotational and capillary rheometers. It was found that at low shear rates smaller filler particles…
Starting from calcium sulfate (gypsum) as fermentation byproduct of lactic acid production process, high-performance composites have been produced by melt-blending polylactide (PLA) and beta-anhydrite II (AII) filler, i.e., calcium sulfate hemihydrate previously dried at 500 degrees C. Characterized by attractive prop…
The charge-neutral antimonatopolyoxovanadium(IV) cluster [V(IV)16Sb(III)4O42(H2O){V(IV)O(C6H14N2)2}4].10H2O.C6H14N2 was obtained under solvothermal conditions. The central cluster fragment, [V(IV) 16Sb(III)4O42], is a derivative of the [V18O42] archetype and is formed by replacing two VO5 polyhedra by two Sb2O5 units.…
High-pressure transitions of ${\mathrm{Ga}}_{2}{\mathrm{O}}_{3}$ and ${\mathrm{In}}_{2}{\mathrm{O}}_{3}$ were examined by using a laser-heated diamond-anvil cell combined with in situ x-ray diffractometry at pressures up to $108\phantom{\rule{0.3em}{0ex}}\mathrm{GPa}$ and $20\phantom{\rule{0.3em}{0ex}}\mathrm{GPa}$, r…
The adsorption on the TiO(2) surface of two dipeptides AE (L-alanine-L-glutamic acid) and AK (L-alanine-L-lysine), that are "building blocks" of the more complex oligopeptide EAK16, has been investigated both theoretically and experimentally. Classical molecular dynamics simulations have been used to study the adsorpt…
Static-lattice calculations have been employed to model the phases of VO 2 and V 1−δ W δ O 2 . Interatomic potentials were empirically fitted to reproduce the low- and high-temperature phases (monoclinic and tetragonal, respectively) of vanadium dioxide as well as the monoclinic phase of tungsten dioxide. For pure VO…
Nanocrystalline V2O5 thin films have been grown at low temperature on glass substrates by dc magnetron sputtering using a vanadium metal target. Film thickness was found to have a great impact on the orientation, shape, and size of the crystallites of these films. X-ray diffraction (XRD) patterns of the films with a t…
Magnetic entropy and adiabatic temperature changes in and above the room-temperature region have been measured for La0.7Sr0.3Mn1−xMx′O3 (M′=Al,Ti) by means of magnetization and heat capacity measurements in magnetic fields up to 6 T. The magnetocaloric effect becomes largest at the ferromagnetic ordering temperature T…
The electromagnetic field solution for a spherical invisibility cloak with an active device inside is established. Extraordinary electric and magnetic surface voltages are induced at the inner boundary of a spherical cloak, which prevent electromagnetic waves from going out. The phase and handness of polarized waves o…
Diamond-like carbon (DLC) films were deposited on glass substrate by sputtering of a vitreous carbon target in Ar + H 2 plasma. The sp 2 /sp 3 content in the films depended on the relative amount of hydrogen in the Ar + H 2 plasma. The films were characterized by Fourier transformed infrared studies, Raman studies, sc…
SU-8 is a chemically amplified, epoxy-based negative photoresist typically used for producing ultrathick resist layers during device manufacturing in the semiconductor industry. As a simple resist, SU-8 has garnered attention as a possible material for a variety of biomedical applications, including tissue engineering…
Five N-aryl-N-pyridylaminoxyls, which have no substituent (PhNOpy), one substituent (MeOPhNOpy and tert-BuPhNOpy) at the 4-position, and three substituents (TPPNOpy and TBPNOpy) at the 2, 4, and 6-positions of the phenyl ring, were prepared as new ligands for cobalt-aminoxyl heterospin systems. The 1:4 complexes, [Co(…
Hierarchical ZnO microspheres constructed by mesoporous quasi-single-crystalline ZnO nanosheets were fabricated by pyrolysis of the microspheres of layered hydroxide zinc carbonate, Zn 5 (CO 3 ) 2 (OH) 6, which was the hydrothermal precipitate of zinc nitrate and urea. A growth mechanism of Zn 5 (CO 3 ) 2 (OH) 6 micro…
Abstract Microencapsulated ammonium polyphosphate (MCAPP) with a melamine–formaldehyde (MF) resin coating layer was prepared by in situ polymerization. MCAPP was characterized by Fourier transform infrared, X‐ray photoelectron spectroscopy, and so on. The results show that the microencapsulation with MF resin leads to…
Electron paramagnetic resonance (EPR) has been used to monitor oxygen vacancies and zinc vacancies in a ZnO crystal irradiated near room temperature with 1.5MeV electrons. Out-of-phase detection at 30K greatly enhances the EPR signals from these vacancies. Following the electron irradiation, but before illumination, F…
We report the growth of undoped and Fe (2 and 5at.%) doped molybdenum oxide thin films on c-plane of sapphire substrate using pulsed laser ablation. X-ray diffraction results show that the films are oriented in the (100) direction and have monoclinic structure based on MoO2 phase as also supported by Raman spectroscop…
Using single-crystal transistors, we have performed a systematic experimental study of electronic transport through oxidized copper/rubrene interfaces as a function of temperature and bias. We find that the measurements can be reproduced quantitatively in terms of the thermionic emission theory for Schottky diodes, if…
