To put a cap on it: Intelligent caps have been added onto mesoporous walls toward innovative low-dielectric materials. Appropriately sized caps at the mesopore entrance is quite effective, which can prevent the penetration of the polymer during the mechanical composite processing and can also provide enough space for…
The hybrid fish Pseudoplatystoma spp. has been raised on a large scale by several fish farmers, despite the fact that little is known about its biology. This is because it presents a number of zootechnical advantages over the parental species. In order to provide information about the early morphology of this importan…
The geometrical structures, relative stabilities, electronic, and magnetic properties of zinc-doped gold cluster anions Au(n)Zn(-) (2 < or = n < or = 10) have been systematically investigated by means of first-principles density functional calculations at the B3LYP level. The results show that the most stable isomers…
Carbon nanotube (CNT) ferroelectric field-effect transistors (FeFETs) with well-defined memory switch behaviors are promising for nonvolatile, nondestructive read-out (NDRO) memory operation and ultralow power consumption. Here, we report two-bit CNT-FeFET memories by assembling two top gates on individual nanotubes c…
A frame-store pn-junction CCD detector was applied to the energy-dispersive X-ray Laue diffraction study of a γ-LiAlO2crystal with white synchrotron radiation. Exploiting the simultaneous spatial and energy resolution of the detector the crystallographic unit cell of γ-LiAlO2could be determined without anya prioriinfo…
The Lu(III) binding mechanisms by trioctahedral smectite hectorite in aqueous systems were investigated by extended X-ray absorption fine structure (EXAFS) spectroscopy. Coprecipitated hectorite (Lu755Hec), its precursor phase (Lu/Brucite), and the surface sorbed hectorite (Lu/SHCa1) were prepared as oriented samples…
The present paper provides an up to date restatement of the wetting behaviour of the series of cyanobiphenyl liquid crystals (LCs) on usual substrates, i.e. oxidized silicon wafers, water and glycerol, at both the macroscopic and microscopic scale, in the nematic range of temperature. We show that on water the systems…
Eu3+-doped GdVO4 has been synthesised via hydrothermal method by altering the hydrothermal temperature, reaction time and surfactant. The microstructure and morphology information of the phosphors were investigated via the techniques of X-ray powder diffraction and scanning electronic microscopy, which show that the p…
Epitaxial crystallization of PTH on highly oriented PE substrate from vapor phase has been achieved. The epitaxial growth of PTH on highly oriented PE substrate leads to the formation of lathlike PTH crystals. The lathlike PTH crystals exhibit well-ordered structure with their long axes preferentially parallel to the…
Abstract The implementation of process intensification by multiscale equipment will have a profound impact on the way chemicals are produced. The shift to higher space‐time yields, higher temperatures, and a confined reaction volume comprises new risks, such as runaway reactions, decomposition, and incomplete conversi…
The europium polyoxometalate anion, [EuW(10)O(36)](9-), can be transferred from an aqueous phase into a chloroform phase through encapsulation by dioctadecyldimethylammonium (DODMA(+)). The formed (DODMA)(9)[EuW(10)O(36)] complexes can self-assemble into ordered, uniform porous honeycomb films by using a simple solven…
Nanostructured regular materials based on dendrimers bound by covalent or coordination bonds between surface functional groups were synthesized. Bimetallic Cu(II) and Pd(II) metal complexes with nitrile-based dendrimers demonstrated high activity in Wacker oxidation of terminal alkenes along with good selectivity for…
We have investigated the effect of titanium substitution on the structure and the magnetic properties of manganites with La 0.67 Ba 0.33 Mn 1− x Ti x O 3 (0 ⩽ x ⩽ 0.3) nominal composition. The polycrystalline samples have been produced by the conventional ceramic method at 1523 K. The morphology, grain size and phase…
POMs de terre: Die Kombination wolframhaltiger Polyoxometallat(POM)-Fragmente mit Gadoliniumkationen führt zu besonders anisotropen Polyoxowolframaten. So ist das Titelpolyanion (siehe Struktur; W grün, As pink, Gd blau, O rot, H2O cyan) fast 5 nm lang – dies macht seine Charakterisierung in Lösung anspruchsvoll, eröf…
Magnetization, susceptibility, specific heat, resistivity, neutron and x-ray diffraction have been used to characterize the properties of single-crystalline ${\text{CaFe}}_{2\ensuremath{-}x}{\text{Ni}}_{x}{\text{As}}_{2}$ as a function of Ni doping for $x$ varying from 0 to 0.1. The combined first-order structural and…
Silicon carbide (SiC) fibers are prepared using an iron‐containing polycarbosilane (Fe‐PCS) as the precursor. Iron pentacarbonyl [Fe(CO) 5 ] is first reacted with low‐molecular‐weight liquid PCS to form an iron‐containing colloid. The colloid is then added into high‐molecular‐weight solid PCS to form Fe‐PCS. Formation…
A novel double liquid crystalline (LC) block copolymer (BCP) composed of poly[ω-(4′-methoxybiphenyl-4-yloxy)hexyl methacrylate] (PMBHMA) and poly{2,5-bis[(4-meth-oxyphenyl)oxycarbonyl]styrene} (PMPCS) was designed and successfully synthesized by reversible addition−fragmentation chain transfer (RAFT) polymerization. W…
The title reaction proceeded well to yield silicon (oxy)nitride at 973–1323 K using a plug‐flow reactor. The degree of nitridation was studied as a function of temperature and time of nitridation, the sample weight, and the flow rate of ammonia. It was dependent on the reaction temperature and the amount of ammonia su…
Abstract Reaction of racemic (dl)‐ or enantiopure (D)‐camphorquinone with P4S10 in dimethylimidazolidinone followed by addition of NiCl2·6H2O or KAuCl4 affords the corresponding bornylenedithiolato metal complexes [(dl‐bordt)2Ni], [(D‐bordt)2Ni], [(dl‐bordt)2Au], and [(D‐bordt)2Au] in their neutral form. Cyclic voltam…
The discovery of a two-dimensional electron gas (2DEG) at the interface between two insulating oxides has recently stimulated intense research activity in this field. The 2DEG has unique properties that are promising for applications in all-oxide electronic devices. For such applications it is desirable to have the ab…
