, respectively. The superior electrochemical activity of M/N-BCNTs can be attributed to its high surface to area volume ratio, unique structural characteristics, ultrahigh electrical conductivity, and carrier mobility.
Abstract In this study, piezoelectric Pb(Zr 0.52 Ti 0.48 )O 3 (PZT) thick films were fabricated on Pt‐coated Si substrates by a modified sol‐gel method via dispersing the piezoelectric submicron powders of composition (Pb, Sr)La x (Ti, Zr) 1−1/4 x O 3 (PZT‐5A, having a high d 33 value of 520 and a high k p value of 0.…
In this study, the chloride adsorption behaviors of CaAl-Cl LDH precursors with various Ca:Al ratios were investigated. The optimal chloride ion removal rate was 87.06% due to the formation of hydrocalumite. The chloride adsorption products of CaAl-Cl LDH precursors were further characterized by X-ray diffraction anal…
Abstract Polycrystalline piezo‐active materials only exhibit a high macroscopic piezoresponse if they consist of particles with oriented crystal directions and aligned intrinsic dipole moments. For ferroelectric materials, the postsynthesis alignment of the dipoles is generally achieved by electric poling procedures.…
Abstract Since the first successful triol-functionalization of the Anderson polyoxometalates, the six protons of their central octahedron X(OH)6 (X?heteroatom, p- or d-element) have been considered as a prerequisite for their functionalization with tripodal alcohols, and therefore, the functionalization of Anderson st…
Abstract Enhancing the production rate while maintaining control in electrospinning has been a challenge for years. This work proposes a novel spinneret from a tube with a single wire loop embedded in its one end. With the feeding of solution precisely controlled and the spinning process stablized, multiple polymer je…
A systematic representation of the fourth-order magnetostriction tensor for all crystal classes is presented, based on the formalism proposed by Walpole ( Proc R Soc Lond Ser A 1984; 391: 149–179). This representation allows the general, unconstrained case, as well as the case in which the magnetostrictive strain is a…
A new class of blue light-emitting supramolecular liquid crystalline cone or bowl-shaped compounds were synthesized from substituted 1,3,4-oxadiazoles and 1,3,4-thiadiazoles with calix[4]arene derivatives.
The reactivity and selectivity of Wells-Dawson type polyoxometalate (POM), K16[Hf(α2-P2W17O61)2]·19H2O (Hf1-WD2), have been examined with respect to the hydrolysis of ovalbumin (OVA), a storage protein consisting of 385 amino acids. The exact cleavage sites have been determined by Edman degradation experiments, which…
In this study, we prepared translucid hydrogels with different concentrations of silk fibroin, extracted from raw silk fibers, and used them as a matrix to incorporate the photosensitizer 5-(4-aminophenyl)-10,15,20-tris-(4-sulphonatophenyl) porphyrin trisodium for application in photodynamic therapy (PDT). The hydroge…
Noninvasive diagnostic by imaging combined with a contrast agent (CA) is by now the most used technique to get insight into human bodies. X-ray and magnetic resonance imaging (MRI) are widely used technologies providing complementary results. Nowadays, it seems clear that bimodal CAs could be an emerging approach to i…
The elastic strain of conventional metals is usually below ∼1%. As the metals' sizes decrease to approximate a few nanometers, their elastic strains can approach ∼8%, and they usually exhibit pseudoelastic strain that can be as large as ∼35%. Previous studies suggested that the pseudoelastic behaviors of nanocrystals…
In the last decade, transparent amorphous oxide semiconductors (TAOS) have become an essential component of many electronics, from ultra high resolution displays to solar cells. However, these disordered oxides typically rely on expensive component metals like indium to provide sufficient charge carrier conduction, an…
Polyimides are used in microelectronics as they possess the essential high tensile properties, high thermal stability and low dielectric constant. As the further reduction in their dielectric constant is indispensable for such applications, in this study it was loaded with the porous covalent organic framework (COF‐LZ…
A novel flame‐retardant chain extension agent (9,10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene‐10‐oxide)‐3,5‐triglycidyl isocyanurate defined as DOPO‐TGIC was synthesized, and its chemical structure was well characterized and confirmed. The effect of DOPO‐TGIC as a synergistic agent on the flame retardancy, rheology, therma…
The coordination environment of titanium of the catalysts was investigated by DRUV–vis, Raman and 47/49 Ti MAS-NMR spectroscopies and solid-state electrochemical techniques.
It is demonstrated that transparent amorphous oxide semiconductors (TAOS) can be excellent thermoelectric (TE) materials, since their thermal conductivity (κ) through a randomly disordered structure is quite low, while their electrical conductivity and carrier mobility (μ) are high, compared to crystalline semiconduct…
New microporous homopolymers were readily prepared from norbornadiene-2,5, its dimer and trimer by addition (vinyl) polymerization of the corresponding monomers with 60–98% yields. As a catalyst Pd-N-heterocyclic carbene complex or Ni(II) 2-ethylhexanoate activated with Na+[B(3,5-(CF3)2C6H3)4]− or methylaluminoxane wa…
Compound samples based on the mineral-like magnesium potassium phosphate matrix MgKPO4 × 6H2O were synthesized by solidification of high level waste surrogate. Phase composition and structure of synthesized samples were studied by XRD and SEM methods. Compressive strength of the compounds is 12 ± 3 MPa. Coefficient of…
Abstract The synthesis of ZnO/SiO 2 nanocomposite doped with Co, Cu and Mn nanoparticles were performed using sol‐gel method. Rietveld refinement analysis was done for the X‐ray diffraction data and results showed that all samples are single wurtzite hexagonal phase and have an average crystallite size ~14 nm. The lat…
