The deposition of Ge onto Si leads to the epitaxial growth of islands with varying morphologies. The size, shape and composition of the islands are all interdependent and change continuously during growth and overgrowth of the islands. A model of the morphological changes is presented that explains various shape chang…
The temperature-induced phase transition of cesium manganese hexacyanoferrate is based on the charge transfer between transition metal ions, and the behavior is complex. To clarify the mechanism for the phase transition, X-ray absorption and magnetic susceptibility were measured. The magnetic susceptibility behavior w…
Abstract A series of well‐defined amphiphilic comb poly (ether amine)s (acPEAs) were successfully synthesized through nucleophilic addition/ring‐opening reaction of commercial available poly(propylene glycol) (PPO) diglycidyl ether and Jeffamine L100, followed by esterification of hydroxyl groups in backbone by alkyl…
The pressure-induced shifts of optical spectral bands 4T2 and 2E for the preferential Cr3+-centered octahedron for Cr3+ at the Sc3+ site of the LiSc (WO 4)2 crystal have been calculated from crystal-field theory. From the calculation, the local linear compressibility d ln R/d p≈−3.3×10−4 kbar−1 for the Cr3+ center in…
Memristive electrical behavior has recently gained attention because of technological advances in nanostructuring, which has enabled the fabrication of working devices. However, such investigations have been limited to mobile ionic systems, and memristive behavior in other types of nanoscale systems has been largely o…
In the title compound, C(21)H(16)N(2)O(3), the fused-ring system (r.m.s. deviation = 0.067 Å) is slightly buckled at the carbonyl C atom of the anthracenyl ring system [deviation = 0.177 (1) Å] that is closer to an allyl substituent. The two allyl units lie on the same side of the fused-ring plane but are oriented in…
To search for new evidence of the chiral p -wave superconducting domain in Sr 2 RuO 4 , we investigated the unconventional local transport characteristics of a microfabricated Sr 2 RuO 4 –Ru eutectic junction. We found that the anomalous hysteresis in voltage–current characteristics [as reported in Kambara et al. : Ph…
Metal-free phthalocyanines(H2Pc) and its derivatives are an important organic electro and photo active material with remarkable chemical stability and flexibility offering considerable interest for many intensive applications. The complexity of the molecule makes the vibrational study of the Raman spectrum difficult.…
In this study 72 different high strength concrete (HSC) mixes were produced according to the Taguchi design of experiment method. The specimens were divided into four groups based on the range of their compressive strengths 40-60, 60-80, 80-100 and 100-125 MPa. Each group included 18 different concrete mixes. The slum…
To improve the understanding on CNT growth modes, the various processes, including thermal CVD, MP-CVD and ECR-CVD, have been used to deposit CNTs on nanoporous SBA-15 and Si wafer substrates with C(2)H(2) and H(2) as reaction gases. The experiments to vary process parameter of DeltaT, defined as the vector quantities…
We investigate the properties of cuprate superconductors subject to applied current, using modified Gutzwiller projected d-wave BCS states. The parent states include quasiparticle and quasihole pockets, of variationally determined size, generated by the current. We identify two different mechanisms for the destruction…
The ligand L1 (N1,N3-di[2-di(2-pyridylmethyl)aminoethyl]N1,N3-dimethyl-1,3-propandiamine) bridges two tripodal units of the amine ligand Me2uns-penp (N1,N1-dimethyl-N2,N2-di(2-pyridylmethyl)-1,2-ethandiamine) with a propyl group. The ligand L1, the dinuclear copper(I) complex [Cu2(L1)](BPh4)2 and the dinuclear copper(…
The electronic structure and the local ordering of Mn:CdTe(110) interface, produced by evaporating at room temperature (RT) 2 ML of Mn on a CdTe(110) single-crystal surface, have been probed by soft x-ray spectroscopies. Strong Mn-Te hybridization effects are found both in core level and valence-band photoemission spe…
Kinetic Monte Carlo simulations of precipitation in AlZr alloys are compared with predictions of cluster dynamics based on an enhanced thermodynamic model. A methodology and various tools are proposed to learn as much as possible from such comparisons. Important deviations between the two methods are investigated and…
BACKGROUND: We have recently reported on the synthesis, characterization and biocompatibility of a novel family of visible-light photocrosslinked poly(diol-co-tricarballylate) elastomers intended for use in drug delivery and tissue engineering applications. In this work, the osmotic-driven controlled release of the wa…
We studied the relationship between the resistive-switching properties of the Pr0.7Ca0.3MnO3(PCMO) thin-film elements and their geometry dimensions below submicrometers. Our electrical test results of a series of PCMO-based resistive-switching devices with different sizes show that switching voltages of ±2.5 V were ac…
We report measurements of inelastic neutron scattering, magnetic susceptibility, magnetization, and the magnetic field dependence of the specific heat for the heavy Fermion compounds ${\text{Ce}}_{3}\text{In}$ and ${\text{Ce}}_{3}\text{Sn}$. The neutron scattering results show that the excited crystal field levels hav…
Abstract Amine‐functionalized and amine‐carboxylate double‐functionalized polymers (I and II, respectively) have been synthesized by a selective single addition of a protected 2‐aminoethyl vinyl ether (BocVE) {CH2 = CH[OCH2CH2N(Boc)2]; Boc = t‐butoxycarbonyl} onto a living cationic poly(n‐butyl vinyl ether) [poly(NBVE…

Eine hydrothermal erhaltene Phase weist eine sehr hohe CO2-Speicherkapazität von 81 L L−1 (27…
This work implements a smart boost converter to enable an electric bicycle to be powered by a battery/supercapacitor hybrid combination. A 36V, 250W front hub motor was retrofitted onto a normal geared bike powered by a 36V; 12Ah lithium ion phosphate battery pack. A 16.2V, 58F supercapacitor module was connected in p…
