We present a study of the anisotropy of the dielectric, magnetic and magnetoelastic properties of the multiferroic clinopyroxene NaFeGe 2 O 6 . Pyroelectric currents, dielectric constants and magnetic susceptibilities as well as the thermal expansion and the magnetostriction were examined on large synthetic single cry…

A new feature of reactivity of iminoborane (HBNH) at the surface of boron nitride nanotube has been revealed by this theoretical study. The HBNH molecule not only selectively breaks the B═N double bond of the BN nanotubes (BNNTs) but also expands the hexagonal network of the tube to larger cages at the surface. Such e…
In the present study, polypropylene, recycled natural rubber gloves, and oil palm ash composites (PP/rNRg/OPA) were prepared using an internal mixer. The effects that OPA loading had on the processability, tensile properties, morphology, and thermal stability of the PP/rNRg/OPA composites were investigated. The stabil…
In this article, we have studied the residence time distributions (RTD) in a modular co‐kneader. Several papers have already addressed the co‐kneader modeling and operating mode but there is still a lack of experimental data on RTD. To investigate the RTD, we have used a colored tracer dispersed in polypropylene (PP)…
The behavior of Fe in the structure of Fe-containing potassium borosilicate glasses with different relationships between network-forming and modifier cations has been studied by Mössbauer and vibrational spectroscopies. The results demonstrate that the Fe-free and Fe-containing potassium borosilicate glasses differ in…
A new design of nonaggregated zinc(II) carboxyphthalocyanines with potential application in dye-sensitized solar cells has been developed. It is based on the introduction of bulky and rigid aryl groups at three α positions of the macrocycle. The synthesis has been carried out following a convergent route in which the…
Thin films of YAlO3:Gd3+ and YAlO3:Gd3+Pr3+ were prepared on LaAlO3 (001) single crystal substrates by pulsed laser deposition (PLD). Both films were grown epitaxially and their surfaces were uniformly smooth. Under UV excitation at 216 nm, YAlO3:Gd3+ film did not show any intense photoluminescence (PL); on the other…
The mechanism of how the neutral block in polyelectrolyte (PE) affects the interaction between PE and surfactants is investigated through coarse-grained simulations. We show that the neutral block plays profound roles on the structural formation of the PE/surfactant complex by assessing the adsorption of surfactants o…
We investigate the mechanical, electronic and magnetic properties of the full Heusler compounds X2MnSn (X = Cu, Ni, Pd) under hydrostatic pressure using the generalized gradient approximation + U method. We present also a comparison between the electronic and magnetic properties provided by DFT and those computed by D…
Dendrimeric macromolecules with defined shape and size are promising candidates for delivering drug or DNA molecules into cells. In this work we study the influence of an amphiphilic polyphenylene dendrimer on a model cell membrane consisting of a condensed 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) lipid mono…
One of the most promising applications of chitosanase is the conversion of chitinous biowaste into bioactive chitooligomers (COS). TKU033 chitosanase was induced from squid pen powder (SPP)-containing Bacillus cereus TKU033 medium and purified by ammonium sulfate precipitation and column chromatography. The enzyme was…
Abstract K 5 Mn 3 O 6 and Rb 8 Mn 5 O 10 have been synthesized via the azide/nitrate route from stoichiometric mixtures of MnO and KNO 3 /KN 3 , or RbNO 3 /RbN 3 , respectively. The two new members of manganese (II/III) mixed‐valent oxides have been studied by single‐crystal X‐ray diffraction, magnetic susceptibility…
The structural and transport properties of polycrystalline ${\mathrm{Ti}}_{1\text{\ensuremath{-}}x}{\mathrm{Pt}}_{x}{\mathrm{Se}}_{2\text{\ensuremath{-}}y}\phantom{\rule{0.28em}{0ex}}(x\ensuremath{\le}0.13,\phantom{\rule{0.28em}{0ex}}y\ensuremath{\le}0.2)$ are studied, revealing highly tunable electrical properties, s…
The Nd 2 S 3 -SnS system has been studied at a temperature of 1100°C. The Nd 2 S 3 solubility in molten SnS at this temperature is determined to be 4.4 mol %. The neodymium is present in the SnS melt in the form of Nd 3+ ions. Its diffusion coefficient in molten SnS is estimated at 1.2 × 10 −8 m 2 /s. Nd 2 S 3 dissolu…
Based on the transfer-matrix method, this paper has investigated the electrical transport properties in monolayer and bilayer graphene superlattices modulated by a homogeneous electric field. It is found that the angular range of the transmission probability can be efficiently controlled by the number of barriers. In…
Metal‐ligand sandwich clusters and molecular wires, which are constituted by metal atoms and organic/inorganic ligands, show potential applications in molecular recognition, catalysis, nanocomposites, optoelectronic, and biological sensors due to their unique structure, electronic, magnetic, and optical properties. Th…
The work considers the possibility of reducing the decomposition temperature of MgCO 3 in dolomite rock, provides the results of studies of the effect of various additives and enhancers on the decomposition of magnesium and calcium components of dolomite. Chlorides additives are the most promising for dolomite rocks r…
ABSTRACT Blends were obtained from polyethylene‐ co ‐acrylic acid (PEAA) with 248 kDa molecular weight and two water soluble biopolymers isolated from the hydrolysate of postharvest tomato plant and urban biowaste compost. The two hydrolysates were constituted respectively from a polysaccharide (SP) with 27 kDa molecu…
The relationship between molecular association and re-entrant phase behavior in polar calamitic liquid crystals has been explored in two families of materials: the 4'-alkoxy-4-cyanobiphenyls (6OCB and 8OCB) and the 4'-alkoxy-4-nitrobiphenyls. Although re-entrant nematic phase behavior has previously been observed in t…
