Exploiting exchangeable covalent bonds as dynamic cross-links recently afforded a new class of polymer materials coined as vitrimers. These permanent networks are insoluble and infusible, but the network topology can be reshuffled at high temperatures, thus enabling glasslike plastic deformation and reprocessing witho…
Hollow structures with high complexity in shell architecture and composition have attracted tremendous interest because of their great importance for both fundamental studies and practical applications. Herein we report the designed synthesis of novel box-in-box nanocages (NCs) with different shell compositions, namel…

From the first-principles calculation, we investigate the electronic transport properties of centrosymmetric carbon nanotube heterojunction with different lengths coupled with between two identical Al(100) electrodes. The results show that the conductance can be modulated with the length of central regular carbon nano…
This paper presents a physicochemical study of Na1 − x Mg1 − x Sc1 + x (MoO4)3 (0 ≤ x ≤ 0.5) glassceramics and oxide glasses containing different amounts of bismuth oxide and having broad glass-forming regions, which allows the composition and properties of the materials to be varied over a rather wide range. We have…
Potassium (K) is one of the essential elements for plants. There has been enough research to determine pollution of nitrogen (N), phosphorus (P), and heavy metals in soil. However, by comparison research on the storage and transport of K has been neglected. Chemical fertilizer usage leads to serious environmental prob…

The electrical conductivity of KMgFe(MoO4)3 crystals has been determined in the temperature range 296–828 K using impedance spectroscopy (5 to 5 × 105 Hz). The potassium magnesium iron molybdate was prepared by solid-state reaction between MgMoO4 and KFe(MoO4)2 at 900 ± 25 K over a period of 200 h. The ionic conductiv…
Abstract Zn‐doped NiO thin films were prepared by sol‐gel spin‐coating method onto transparent conducting substrates using nickel acetate tetrahydrate and zinc acetate dehydrate as starting precursors. Effects of zinc doping content on the structural, optical and electrochromic properties of NiO films were investigate…
Abstract The heptacoordinate transition metal coordination compound [Cd(SCZ) 3 (H 2 O)](PA) 2 · 3H 2 O ( 1 ) with the ligand semicarbazide (SCZ) and the counteranion picrate (PA) was synthesized and characterized by elemental analysis and FTIR spectroscopy. Single‐crystal X‐ray diffraction analysis revealed that 1 cry…
The temperature evolution of the electronic structure of a Ni-Fe(Co)-Ga/MgO(100), Heusler-type, ferromagnetic shape-memory alloy thin film has been followed by a bulk-sensitive hard x-ray photoelectron spectroscopy, element-selective soft x-ray magnetic circular dichroism, and first-principles calculation. The reversi…
We formulate and analyze an optimization-based Atomistic-to-Continuum (AtC) coupling method for problems with point defects. Application of a potential-based atomistic model near the defect core enables accurate simulation of the defect. Away from the core, where site energies become nearly independent of the lattice…
Tripolar cups can be separated into constrained and unconstrained dual-mobility cups. The latter show better survival and revision rates. The main problem is the polyethylene wear. Therefore modern types of polyethylene are used in these cups. The indications for dual-mobility cups are recurrent dislocation and situat…
Abstract The paper aims at the investigation of atmospheric pressure weakly ionized plasmas with argon and acetylene to deposit plasma-polymerized coatings on wood veneers (birch, maple), cellulose paper, and pine wood flour to modify their surface properties, in particular their topography and wettability. The treatm…

The annealing effect on the thermoluminescence (TL) characteristics of x-ray irradiated muscovite mineral relevant to dosimetry has been studied. For un-annealed and 473 K annealed samples an isolated TL peak has been observed at around 347 K; however, annealing at 573, 673 and 773 K two composite peaks have been reco…
Abstract Thermal analysis was applied to determine the liquidus temperatures in the NaCl–KCl–BaCl 2 –BaO system, with BaO concentration varied from 0 to 6 mole%. The temperature dependence of the BaO solubility in the NaCl–KCl–BaCl 2 eutectic melt was investigated; the thermodynamic parameters of BaO dissolution were…
This work introduces metallo-dielectric woven fabric as a metamaterial for phase-front manipulation. Dispersion diagram as well as effective medium parameters retrieved from reflection and transmission coefficients point out negative values of refractive index. By numerical simulations, it is evidenced that a pair of…
This paper reports the effect of sintering temperature on the structural, optical and ferroelectric properties of vanadium (V) doped zinc oxide (ZnO) samples. X-ray diffraction (XRD) study confirms the formation of a hexagonal wurtzite phase. It has been found that the increase in sintering temperature leads to very s…
