Structural developments are investigated in network-forming reactive polymers by time- and space-resolved scanning Brillouin microscopy. Hypersonic properties are probed to reveal the subtle interplay between molecular transport, dissolution, polymerization and network defects in the vicinity of the interface between…
We report the first synthesis of periodic mesoporous silicas templated by bicelles. The obtained materials form novel pillared lamellar structures with a high degree of periodic order, narrow pore size distributions, and exceptionally high surface areas.
Comb- and fishbone-like doped ZnO nanostructures were synthesized by introducing different dopants in alloying vapor deposition process. Whereas, Al and Sn doping could induce comb-like structures, In doping introduced fishbone-like structures due to different chemical activity of dopants involved. While belts exhibit…
Recent experimental and theoretical results show that interlayer bonds in multiwalled carbon nanotubes (MWCNTs) play a pivotal role in improving their mechanical and electronic properties desirable for device applications. However, generation of interlayer bonds while maintaining tube structural integrity remains a ke…
Polymorphs have a tendency to undergo solution-mediated transformation from one form to another during crystallization. Various in situ techniques explored for understanding the crystallization process include, Raman spectroscopy, near-infrared spectroscopy (NIR), and focused beam reflectance measurement (FBRM). Both…
The interfacial structure, stability, electric polarization, and electronic properties for ${\text{PbTiO}}_{3}/{\text{SrTiO}}_{3}$ (PTO/STO) superlattice are studied by first-principles calculations. Based on the work of separation for different stacking interface configurations, including stoichiometric normal stacki…
Herein, we describe the preparation of a 2,2'-bipyridine derivative containing a redox-active N,N'-(4,4'-dimethoxydiphenylamino) substituent (1), which readily coordinates M(hfac)(2) salts [M = Mn (2), Ni (3), Cu (4)] to generate stable, neutral, and pseudo-octahedral coordination complexes, which have been fully char…
The morphology and biaxial texture of vacuum evaporated CaF(2) films on amorphous substrates as a function of vapour incident angle, substrate temperature and film thickness were investigated by scanning electron microscopy, x-ray pole figure and reflection high energy electron diffraction surface pole figure analyses…
Lead-based piezoelectric ceramics, represented by Pb(Zr,Ti)O 3 (PZT) and PZT-based multicomponent materials, have been widely used for piezoelectric actuators, sensors, transducers as well as microelectronic devices due to their excellent piezoelectric properties.
The interactions of furan and its hydrogenated derivatives (2,3-dihydrofuran, 2,5-dihydrofuran, tetrahydrofuran, and diethyl ether) with the isolated silanol groups at the surface of a highly dehydrated amorphous silica have been investigated by means of IR spectroscopy, at both constant and variable temperature. The…
This paper presents a method to separate the reversible and irreversible parts of magnetization in real ferromagnetic systems. The basic hypothesis is that the first-order reversal curve (FORC) diagram includes effects of both the reversible and irreversible components while the remanent second-order reversal curve (S…
The anisotropic superconducting properties of the LaRu 2 P 2 single crystal have been systematically investigated by magnetic and transport measurements. Both the upper critical field ( H c2 ) and the lower critical field ( H c1 ) show isotropic behavior, indicating the three-dimensional nature of its Fermi surface to…
The dynamics of bulk toluene and toluene confined in the 1,2-O-(1-ethylpropylidene)-α-D-glucofuranose gel was studied using (1)H field-cycling nuclear magnetic resonance relaxometry. The proton spin-lattice relaxation time T(1) was measured as a function of the magnetic field strength and temperature. The observed dis…
The reactions of NiSO 4 ·6H 2 O or Mn(CH 3 COO) 2 ·4H 2 O with the planar ligands of indane-1,2,3-trione trioxime (H 3 Itto) or indane-1,2,3-trione-1,2-dioxime (H 2 Itdo) gave two planar pentanuclear clusters [Et 3 NH] 2 [Ni 5 (HItto) 4 (MeOH) 2 (H 2 O) 6 (SO 4 ) 2 ]·2H 2 O ( 1 ) and [Ni 5 (HItdo) 2 (Itdo) 2 (DMF) 4 (…
Nanoparticles of iron boride (Fe2B, Fe2B coated in SiO2, FexCo2−xB coated in SiO2) were synthesized using the reduction of metal ions by sodium borohydride. X-ray diffraction confirms the amorphicity of the coated compounds and scanning electron microscope imaging revealed the nanoparticulated structure of all compoun…
Abstract A series of novel phosphorus‐containing polyesterimides were prepared from diols—a mixture of a new aromatic phosphorus‐containing bisphenol, namely 1,4‐bis[ N ‐(4‐hydroxyphenyl)phthalimidyl‐5‐carboxylate]‐2‐(6‐oxido‐6H‐dibenz<c,e><1,2>oxaphosphorin‐6‐yl)‐naphtalene, with aliphatic diols such as 1…
Dopants are non-native atoms commonly used to modify the properties of bulk semiconductors. In this paper we demonstrate that by controlling the addition of cobalt(II) to growing zinc oxide nanocrystals (ZnO NCs) it is possible to modulate the resulting properties. We show that the environment of cobalt may be control…
Various hybrid functionals (B3LYP, B97-2, PBE0, BMK, BH&HLYP, CAM-B3LYP, and LC-ωPBE) implemented in density functional theory were applied to give estimate of static first hyperpolarizabilty (β(0)) of (E)-benzaldehyde phenylhydrazone designated as (E)-BPH. Against those of MP2 computations as a function of the underl…
Manufacturing of leucite glass-ceramics often leads to materials with inhomogeneous microstructures. Crystal-glass thermal mismatches which produce microcracking around larger crystals-agglomerates are associated with reduced mechanical properties. The hypotheses were that fine (< 1 µm) crystal size and uniform micros…
The transport of liquid droplets on surfaces carrying reactants offers advantages in the creation of fluidic devices crucial for life science applications. In a majority of situations, a selection of these droplets on a surface, rather than all of them, will need to be moved at any one time. It is a formidable challen…
