Radio frequency (RF) detection of partial discharges (PD) is a long-established principle, being described in the international standard for partial discharge measurement. The growing market for mobile communication devices in recent years has led to big reductions in the cost of electronic hardware operating in the V…
The defect chemistry of Yb3+:CaTiO3 solid solutions has been investigated both theoretically and experimentally. Three different incorporation mechanisms with similar solution energy were predicted for Yb3+ by atomistic simulation: (i) Ca site substitution with Ca vacancy compensation; (ii) Ti site substitution with O…
Direct electrodeposition of macroporous tin is achieved in a water- and air-stable room-temperature ionic liquid, namely, 1-ethyl-3-methylimidazolium-dicyanamide. This is the first example showing that tin nanowires interweaving into a porous structure can be obtained in ionic liquid without using any additive and tem…
Aliphatic copolyesters of succinic acid (SA) and dimerized fatty acid (saturated dilinoleic acid (DLA)) were synthesized via direct copolycondensation in the presence of 1,4-butane- diol. The thermal and mechanical properties of these copolymers were investigated as a function of the hard/soft segments' ratio. The res…
Abstract The review addresses features of special interest concerning two classes of functionalized semiconducting polymers: poly(aryleneethynylene)s (PAEs) bearing biomolecules as chiral nonracemic pendant groups and poly(phenylenevinylene)s (PPVs), which are fluorinated in various positions of the repeating units. M…
Well-defined heterobi- and heteropolymetallic alkoxides are valuable precursors for numerous oxide materials with great application potential. Simple and high yield synthetic routes to such compounds are always highly desirable. This Perspective describes one of the methods that utilizes, as starting materials, homole…
Understanding the mechanical properties of technologically advanced materials from quantum mechanical predictions based on electronic structure calculations remains one of the most challenging problems in modern computational materials science. In this paper, we illustrate this challenge from our current investigation…
The aim of this work is to review the latest developments in glass science and technology. It presents various types of glass, of both academic and technological importance, in which the host is doped with rare-earth ions.Glass science has reached a very interesting stage in its development, with scope for a wider-ran…
During the last decades, the advancements in micro- and nano- technology have brought tremendous encouragement to the current biomedical research. Porous silicon (pSi) has many interesting properties that are being investigated for diverse biomedical applications, including biomolecular screening, optical biosensoring…
The geometric structure，band structure and density of state of pure and N-Ga，2N-Ga codoped wurtzite ZnO have been investigated by first-principles ultrasoft pseudopotential method in the generalized gradient approximation. The calculation results show that the codoped structure N-Ga has better stability. Our work indi…
The first examples of lanthanide complexes with a 2-hydroxyisophthalate ligand are reported; the blue-emitting ligand acts as a very efficient sensitizer of the Tb(III) green emissions and does so in the near-UV region.
Two azopolymers (DACENO2 and DACEOCH3) with a special structure were designed and synthesized. The azopolymer films doped with the lanthanide complex Eu(TTA)3Phen were prepared by a casting method with a mixed solution of the azopolymer and lanthanide complex. UV-vis spectra show that the absorption peaks of the prede…
The difference in steric profiles for eta(5) and eta(1)-pyrrolyls can be used to modify barriers for pyrrolyl exchange. The method investigated incorporated 1,3-diaxial interactions in a cyclohexyl backbone of the dipyrrolylmethane. Some of the enthalpic barrier created with the 1,3-steric interactions appears to be m…

Photoluminescence and energy transfer in , are investigated as a function of concentrations. The energy transfer rates are…
Abstract Stabilization of metal nanoparticles (MNPs) in polymeric matrices of different types has proven to be one of the most promising strategies to prevent their aggregation and to retain their properties. Polymer-stabilized MNPs (PSMNPs) and those based on polymer-metal nanocomposite materials are starting to find…
A micro-bead sandwich assay for P38 mitogen-activated protein kinase using surface enhanced resonance Raman spectroscopy (SERRS) detection is reported. Monoclonal capture antibodies were immobilised on a solid phase of magnetic micro-beads with secondary detection using a rhodamine-labelled antibody. Quantitative SERR…
Results of in situ UV-visible (UV/vis) spectroelectrochemical studies of the electro-oxidation of o -phenylenediamine (OPD), o -toluidine (OT), and their mixtures, as well as the redox activity of the obtained polymer films, performed in an aqueous acidic solution at an indium-doped tin oxide-coated glass electrode, a…
A study of group velocity dispersion of horizontal slot waveguides filled by Si nanocrystals with different Silicon concentrations has revealed a change in the sign of GVD from negative to positive values across the third telecom window.
A new bromocoumarin-based bi-functional linker was developed for preparing photocleavable peptides and proteins with high photolytic efficiency, which have many potential applications in the study and engineering of biological systems.
This tutorial review discusses basic features of electronic multipoles and their ordering phenomena. Starting with classification of electric and magnetic higher multipoles under spherical symmetry, we proceed to two representative cases with strong spin-orbit interaction. First, staggered octupole orders in Ce1-xLaxB…
