Magnetite-ENR polymer electrolytes doped with various % wt of LiCF3SO3 salt were synthesized in-situ in the presence of ENR and cast into film doped with LiCF3SO3. XRD results confirmed the purity of the as-formed magnetite particles. The diffraction peaks assigned for LiCF3SO3 become more intense as the concentration of salt is increased. FTIR analyses showed that both “free” (dissociation) an...

Introduction Man’s war against dangerous afflictions has led to the development of potent formulations and requires complicated dosage patterns. They require controlled and targeted delivery to maximize therapeutic efficacy and minimize side-effects. Chemotherapy has been recognized as a successful means of arresting cancer, which is the third biggest killer among humans. Cancerous tumors are c...

The hybridization of semiconductor optoelectronic devices and nanomechanical resonators provides a new class of optomechanical systems in which mechanical motion can be coupled to light without any optical cavities. Such cavity-less optomechanical systems interconnect photons, phonons and electrons (holes) in a highly integrable platform, opening up the development of functional integrated nano...

In this study, the performance and stability of inverted bulk heterojunction (BHJ) polymer solar cells (PSCs) is enhanced by doping zinc oxide (ZnO) with 0-6 wt % cetyltrimethylammonium bromide (CTAB) in the sol-gel ZnO precursor solution. The power conversion efficiency (PCE) of the optimized 3 wt % CTAB-doped ZnO PSCs was increased by 9.07%, compared to a PCE of 7.31% for the pristine ZnO dev...

The adsorption of hydrogen sulfide molecule on undoped and N-doped TiO2/Au nanocomposites was investigated by density functional theory (DFT) calculations. The results showed that the adsorption energies of H2S on the nanocomposites follow the order of 2N doped (Ti site)>N-doped (Ti site)>Undoped (Ti site). The structural properties including bond lengths, angles<span id="...

A solution state polymer diode, which uses regioregular poly(3-hexylthiophene-2,5-diyl) (P3HT):dichlorobenzene solution as the semiconductor between highly doped p-type silicon and aluminum electrodes has been built. Electrodes separated by a 40 nm gap enable intra-chain charge carrier transfer through the lengths of single polymer chains. This prevents chain to chain hopping and chain entangle...

Received 16.11.2015, received in revised form 17.01.2016, accepted 02.03.2016 The paper describes research of biomedical applications of experimental polymer devices prepared from polyhydroxyalkanoates (PHAs) in the Institute of Biophysics SB RAS and Siberian Federal University (Krasnoyarsk, Russia) between 2000 and 2012. The high-purity PHA specimens were investigated and then used to prepare ...

A novel reagentless direct electrochemical DNA sensor has been developed using ultrathin films of the conducting polymer polypyrrole doped with an oligonucleotide probe. Our goal was to develop a prototype electrochemical DNA sensor for detection of a biowarfare pathogen, variola major virus. The sensor has been optimized for higher specificity and sensitivity. It was possible to detect 1.6 fmo...
