A type of polyaniline was synthesized and its Cr (VI) removal potential was investigated in this work. The kinetics study, adsorption isotherm, pH effect, and thermodynamic study were examined in batch experiments. Adsorption data for Cr (VI) uptake by polyaniline were analyzed according to Langmuir and Freundlich ads…
The properties of the humidity sensors made of chemically treated and untreated multi-walled carbon nanotube (MWCNT) thin films are investigated systematically. It shows that both the chemically treated and untreated MWCNT thin films demonstrate humidity sensitive properties, but the former have stronger sensitivity t…
We proposed a CdSe quantum dot (QD)-sensitized solar cell (QDSSC), which is constructed with a CdSe QD adsorbed TiO2 nanotube working electrode on a Ti substrate, a ring shaped Cu2S counter electrode, prepared on a brass substrate having a glass window, and polysulfide electrolyte. The light was incident from the coun…
A pyrrolyl-based triazolophane, incorporating CH and NH donor groups, acts as a receptor for the pyrophosphate anion in chloroform solution. It shows selectivity for this trianion, followed by HSO(4)(-) > H(2)PO(4)(-) > Cl(-) > Br(-) (all as the corresponding tetrabutylammonium salts), with NH-anion interactions being…
This paper reviews the literature on the composting process, which is one of the technological options for the processing of municipal solid wastes (MSWs). The process assumes a great significance, particularly from the point of its economic viability, capability for recycling of nutrients and waste minimization with…
The CESA1 component of cellulose synthase is phosphorylated at sites clustered in two hypervariable regions of the protein. Mutations of the phosphorylated residues to Ala (A) or Glu (E) alter anisotropic cell expansion and cellulose synthesis in rapidly expanding roots and hypocotyls. Expression of T166E, S686E, or S…
We show that the interplay between spin and charge fluctuations in Sr₂RuO₄ leads unequivocally to triplet pairing which has a hidden quasi-one-dimensional character. The resulting superconducting state spontaneously breaks time-reversal symmetry and is of the form Δ ~(p(x)+ip(y))z(^) with sharp gap minima and a d vect…
The thermoelectric transport through a molecular bridge is discussed with an emphasis on the effects of inelastic processes of the transport electrons caused by the coupling to the vibrational modes of the molecule. In particular, it is found that when the molecule is strongly coupled to a thermal bath of its own, whi…
A systematic study of GaN-based heterostructure field-effect transistors with an insulating carbon-doped GaN back barrier for high-voltage operation is presented. The impact of variations of carbon doping concentration, GaN channel thickness, and substrates is evaluated. Tradeoff considerations in on-state resistance…
The emitting triplet state of fac-Ir(ppy)(3) (fac-tris(2-phenylpyridine)iridium) is studied for the first time on the basis of highly resolved optical spectra in the range of the electronic 0-0 transitions. For the compound dissolved in CH(2)Cl(2) and cooled to cryogenic temperatures, three 0-0 transitions correspondi…
We developed two-step solution-phase reactions to form hybrid materials of Mn(3)O(4) nanoparticles on reduced graphene oxide (RGO) sheets for lithium ion battery applications. Selective growth of Mn(3)O(4) nanoparticles on RGO sheets, in contrast to free particle growth in solution, allowed for the electrically insula…

Temperature dependence of the electrical conductivity and photoluminescence (PL) in Au nanoclusters (NCs) is investigated. The correlation of the conductivity and PL in Au NCs at different temperatures is evident: (i) for T<50 K, both the conductivity and PL intensity decrease with temperature, which suggests t…
Oligophenyl-based swivel cruciforms are an amorphous class of materials for potential use in display applications. In this work, we describe the design, synthesis, and structural and optical properties of a group of chromophores with varying degrees of π-conjugation that produce blue emission and high photoluminescenc…
The light-emission efficiency in Si LEDs with nanoscale trench structure on the top surface can be enhanced about ten times than it in the control planer device. The photonic-crystal effect, the characteristics of the special wavelength extraction, is also observed successfully. The experimental data agree well with t…
Abstract Monte Carlo simulations are performed to study the binding of peptides (M1: 1 H 2 G 3 I 4 N 5 T 6 T 7 K 8 P 9 F 10 K 11 S 12 V) to a stack of mobile clay platelets and evaluate the morphological responses on a cubic lattice. A coarse‐grained description is used to model both platelets and peptides capturing t…
Several molecules are known to contain stable silicon double or triple bonds that are sterically protected by bulky side groups. Through first-principles computation, we demonstrate that well-defined π bonds can also be stabilized in a prototypical crystalline Si structure: Schwarzite Si-168, when modest negative pres…
This paper examines the microstructure of sintered magnesia partially stabilized zirconia (Mg–PSZ) with alumina and titania additions. Two effects are mainly responsible for enhanced thermal shock performance, microcrack generation by zirconia destabilization and in situ spinel formation as well as development of a du…
Abstract Zirconium alloys are commonly used in pressurized water reactor as fuel rod cladding tubes. After irradiation and cooling in pool, the spent nuclear fuel assemblies are either transported for wet storage to a devoted site or loaded in suitable casks for dry storage on a nuclear power plant site. During dry tr…
Abstract For the first time, poly(ε‐caprolactone) and poly(ε‐caprolactone‐ co ‐ε‐caprolactam) nanoparticles were successfully obtained by anionic polymerization of ε‐caprolactone and anionic copolymerization of ε‐caprolactone with ε‐caprolactam, respectively, in heterophase by the miniemulsion technique. After polymer…
