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…
Reactions of N,N,N',N'-tetrakis(2-hydroxyethyl)ethylenediamine (H(4)edte) with MnCl(2).4H(2)O or FeCl(3).6H(2)O in MeOH or MeCN with different bases yield four butterfly-like tetranuclear clusters with fused defective dicubane M(4)O(6) cores: [Mn(II)(2)Mn(IV)(2)(mu(4)-Hedte)(2)(thme)(2)].MeCN () (H(4)edte = N,N,N',N'-…
Two novel enantiopure bis(pyrrolo[3,4-d])tetrathiafulvalene derivatives, substrates for preparing chiral conducting materials, show chiral crystal packing arrangements in which successive layers are rotated in accordance with an exact or approximate 43 axis. The corresponding donors containing fused dihydropyrrole gro…
A comparison of experimental results with numerical simulations is presented that shows the influence of electrode geometry on the impedance response for reactions involving one adsorbed intermediate. The local electrochemical impedance measurements performed on an iron disk electrode were in qualitative agreement wit…
Biodegradable porous polyurethanes scaffold have themselves opportunities in service, in-cluding controlled degradation rate, no-toxic degradation products. However, polyurethanes are lack of bioactive groups, which limits their application. This review gives the common modification methods, surface functionalization…
