First-principles calculations of the thermodynamic properties of Ti2AlC and Ti2SC were carried out. The temperature dependence of bulk modulus, the pressure dependence of normalized volume V⁄V0, thermal expansion coefficient, specific heats, and Debye temperature were successfully obtained through the quasi-harmonic D…
Triangular trinuclear Co(iii), Rh(iii), and Ir(iii) dithiolene complexes, [[M(3)(eta(5)-C(5)Me(5))(3)(S(6)C(6))] (M = Co, Rh, Ir), which have not been obtained by the trimerization of mononuclear complexes, were synthesized via a new synthetic route, that is, the reaction of benzenehexathiol and [(eta(5)-C(5)Me(5))Co(…
Porous tungsten oxide films of nanocrystalline tungsten oxide embedded in an amorphous tungsten oxide matrix have been synthesized via poly(ethylene glycol) (PEG)-template sol-gel technique with peroxopolytungstic acid precursor. The effects of PEG addition on the microstructure and electrochromic performance of the t…
The adsorption and self-assembly of alpha,omega-aliphatic diamines on silver nanoparticles is studied in this work by surface-enhanced Raman scattering (SERS) spectroscopy and plasmon resonance. These bifunctional diamines can act as linkers of metal nanoparticles (NPs) inducing the formation of hot spots (HS), i.e. i…
A general concept for oxidation-state control of nanoparticles synthesized via chemical reduction has been developed. By comparing kinetically determined mixed potential measured in reaction solution and thermodynamically drawn potential diagrams, e.g., potential–pH diagram, it is possible to know “what chemical speci…
The poor performance of natural fibres as composite reinforcements where the focus on chemical aspects has not yet delivered the "holy grail" of glass fibre replacement in volume applications is discussed. An explanation is proposed based on the anisotropic structure of these fibres and its influence the composite int…

Dynamical simulations of polaron transport in conjugated polymers in the presence of an external time-dependent electric field have been performed within a combined extended Hubbard model (EHM) and Su-Schrieffer-Heeger (SSH) model. Nearly all relevant electron-phonon and electron-electron interactions are fully taken…
In this paper we develop an analytical framework for the study of electrochemical impedance of mixed ionic and electronic conductors (MIEC). The framework is based on non-equilibrium thermodynamics and it features the coupling of electrochemical reactions, surface transport and bulk transport processes. We utilize thi…
Electric-Field-Induced Mass Movement of Ge2Sb2Te5 in Bottleneck Geometry Line Structures, Nam, Sung-Wook, Lee, Dongbok, Kwon, Min-Ho, Kang, Dongmin, Kim, Cheolkyu, Lee, Tae-Yon, Heo, Sung, Park, Young-Wook, Lim, Kipil, Lee, Hyo-Sung, Wi, Jung-Sub, Yi, Kyung-Woo, Khang, Yoonho, Kim, Ki-Bum
In many cases, to obtain the required extent of protection against electromagnetic radiation (EMR) emitted by operating electrical and electronic devices, it is not enough to use only shielding materials that non-transmit the radiation as a results of its reflection, but it is in dispensable to use shields (materials)…
The aim of the research was to reveal features of the electrical charging and dissipation of charges in fabrics containing conductive yarns after washing. All fabrics investigated were woven at the Lithuanian Textile Institute as protective fabrics from incendiary discharges. Conductive yarns were inserted into the fa…
The characterization of the proton sorptive properties of calcite in aqueous solutions at 25 +/- 1 degrees C over a relatively wide range of chemical conditions (7.16 <or= pH <or= 9.7; 3 x 10(-5) M <or=SigmaCa <or= 5 x 10(-3) M; 10(-4) M <or=SigmaCO(2)<or= 1.7 x 10(-3) M) and solid : solution ratios (0.4 to 12.3 g L(-…
An ideal metamaterial is composed of identical elements in a uniformly structured array so that the material response is a single magnetic or electric resonance. Variations in the metamaterial particle characteristics or array assembly result in undesirable broadening of the effective material response. When lumped ci…
Multifrequency continuous wave (cw) and echo-detected (ED) electron paramagnetic resonance (EPR) was employed to study the mobility of nitroxides confined in nanocapsules. The complexes p-hexanoyl calix[4]arene with 4-methoxy-2,2,6,6-tetramethylpiperidine-N-oxyl (MT) and N-(2-methylpropyl)-N-(1-diethylphosphono-2,2-di…
A new compound, [Fe(5–Cl-qsal)2][Ni(α-tpdt)2].CH3CN, where α-tpdt = 2,3-thiophenedithiolate and H5–Cl-qsal = N-(8-quinolyl)-5-chlorosalicylaldimine, was prepared and structurally and magnetically characterized. The crystal structure is based on an arrangement of alternate layers of [Fe(5–Cl-qsal)2]+ cations and [Ni(α-…
The present work demonstrates for the first time a template-free, single-step electrochemical method to synthesize ZnO hollow nanospheres with diameter in the range of 20–200 nm, which are formed by self-assembly of ZnO nanoparticles of <10 nm diameter.
Abstract Clay minerals are present in most sedimentary rocks. They find applicability in a wide range of disciplines, such as material, soil, earth, environmental, and biological sciences. Despite their abundance and use, swelling of clays under stress has not received enough scientific attention. We used a two-method…
Zinc oxide is a fascinating material with a combination of catalytic, electronic, optical, piezoelectric, and spintronic functionalities. It also has the most diverse configurations of simple or complex structures. ZnO therefore provides an ideal material platform for the construction of devices with micro- and/or nan…
The leaching of acetyl tributyl citrate (ATBC) from plastic kitchen wrap into water, aqueous acetic acid solution, and aqueous skim milk solution heated to 60°C was investigated. A new extraction method was developed to determine the leaching rate. It was found that ATBC is prone to migrate into protein liquids, such…
