Design of a highly sensitive photonic crystal waveguide platform for refractive index based biosensing
In this paper, a photonic crystal waveguide platform on silicon-on-insulator substrate is proposed in order to realize a highly sensitive refractive index based biosensor. Following the design, the analysis of the sensor structure are made by using the three dimensional Finite Difference Time Dom...


Temperature and gate bias dependence of carrier transport mechanisms in amorphous indium–gallium–zinc oxide thin film transistors
The electrical properties of amorphous indium–gallium–zinc oxide thin film transistors are measured in the temperature range from 70 to 300K. The device shows normal enhancement mode operation with significantly reduced drain current at low temperature. Its turn-on voltage and subthreshold sw...
Influences of calcination temperature on growth and superconducting properties of GdBa2Cu3O7-δ films fabricated by fluorine-free metal organic deposition method
GdBa2Cu3O7-δ is one of the best candidates for the superconducting coated conductors because it has high critical temperature and high critical current density under high magnetic fields. In this study, superconducting GdBa2Cu3O7-δ films were fabricated by fluorine-free metal organic deposition...
Semantic image segmentation using low-level features and contextual cues
Semantic image segmentation aims to partition an image into non-overlapping regions and assign a pre-defined object class label to each region. In this paper, a semantic method combining low-level features and high-level contextual cues is proposed to segment natural scene images. The proposed me...
Enhanced high rate and low temperature electrochemical properties of LiFePO4/C composites by doping samarium ion
The olivine-type samarium-doped LiFe1 − xSmxPO4/C (x = 0, 0.01, 0.02, 0.03, 0.04, and 0.05) composites were synthesized via liquid-phase precipitation reaction combined with the high-temperature solid-state method. The structure, morphology, and electrochemical performance of the samples we...

Women played and still play an outstanding role in the development of electrochemistry and electroanalysis at the universities and research institutes of the former Soviet Union. This paper is focussed on the life and achievements of Ol’ga Al’fredovna Songina and her contributions to the deve...


Compatibility between LiNi0.5Mn1.5O4 and electrolyte based upon lithium bis(oxalate)borate and sulfolane for high voltage lithium-ion batteries
To seek the compatibility between LiNi0.5Mn1.5O4 and electrolyte based upon lithium bis(oxalate)borate (LiBOB) and sulfolane (SL), the electrochemical performances of 0.7molL−1 LiBOB–SL/DMC (1:1) electrolyte are investigated. This electrolyte has characteristic of good stability against oxida...
Electrochemically active surface area effects on the performance of manganese dioxide for electrochemical capacitor applications
The specific surface area, morphology and electrochemical performance of thin films of electrodeposited manganese dioxide have been examined. Electrodeposition of these films was carried out using chronoamperometry, using times ranging from 10 to 120s in order to obtain deposits with different ma...
High-efficient dye-sensitized solar cells with all-inorganic Cu2ZnSnSe4 counter-electrode by ligand exchange
For the first time, we synthesized all-inorganic Cu2ZnSnSe4 nanocrystals (CZTSe NCs) by ligand exchange strategy using a simple metal-free chalcogenide compound [(NH4)2S] as the inorganic ligand. The results of I–V and Hall-effect measurement illuminated that all-inorganic CZTSe films reveal th...

Dependence of electrochemical charging of gold nanoparticle monolayer films on counterion proximity
Herein we report the nontrivial effect of counterion size on the electrochemical charging of gold nanoparticle (or called MPC) monolayer films in aqueous electrolyte solutions. The electrochemical charging response was observed with relatively small counterions (e.g., BF4 −, ClO4 − and PF6 âˆ...
The open circuit potential of Geobacter sulfurreducens bioanodes depends on the electrochemical adaptation of the strain
Bioanodes for acetate oxidation were formed with pure cultures of Geobacter sulfurreducens under constant polarization potential. With the original commercial strain, the bioanodes formed at +0.2V/SCE exhibited open circuit potential (OCP) of 0.0V/SCE, while the bioanodes formed at −0.2V/SCE ha...
Electrocatalysis of H2O2 reduction/oxidation at model platinum surfaces
Oxidation (HPOR) and reduction (HPRR) reactions of hydrogen peroxide were studied on platinum single crystalline surfaces. Experimental curves were fitted to a simple model in which the whole process is described by the sum of two independent, mass controlled reactions. It is shown that stepped s...
