Micro energy storage devices have drawn increasing attention due to the importance of power supply in miniaturized multi-functional systems. This paper reviews the recent progress in micro energy storage devices, particularly the micro supercapacitors, including the design issues of device architectures, electrode mat…
The present work focuses on the microstructure of annealed damascene Cu interconnects with different trench aspect ratio and line spacing. The X-ray diffraction (XRD) and electron backscatter diffraction (EBSD) measurements are conducted on the surface of Cu interconnects after removal of the SiN layer. The experiment…
Based on the Boltzmann transport equation in the MRT approximation, we present a theory to investigate low-field carrier transport in dual-gated silicene FETs by taking into account screened charged impurity scattering, which is the most likely scattering mechanism limiting the conductivity. Static RPA dielectric scre…
The overall cable insulation condition can be monitored continuously by the implementation of an on-line partial discharge (PD-OL) monitoring system. It can both detect and locate the sources of PDs and also assess the insulation condition by using past data. The utilization of an accurate electromagnetic transient mo…
There is a high demand in the textile industries for environment friendly processes with minimum wastewater generation. In addition, the reduction of oil reservoirs has led to an increased interest in production of biodegradable polymers from renewable natural recourses like plants. Poly-lactic-acid (PLA) , the fist s…
Modified by the pretreated model with collagen under the crosslinking effect of glutaraldehyde, the moisture absorption of modified samples increased by 26.34% and 42.6%. The test results of SEM, AFM and DSC show that there was coating on the fibers modified with collagen, and the relative average roughness of the mod…
Neodymium doped sodium bismuth silicate glasses were prepared by the melt quench technique. Optical absorption spectra of the Nd3+ion in the present glassy systems were recorded in the UV-Vis-NIR region. Taylor series expansion method was adopted for theoretical evaluation of various crystal field parameters such as t…
High quality pure color quantum dots (QDs) were synthesized and employed to fabricate QDs light converting film (QDF). The advanced QDs film (AQDF) with embedding of nano‐TiO 2 particles demonstrated excellent luminescence with 66.48% of light power conversion efficiency (CE), which is higher than that of normal QDF (…
The paper continues the discussion of original studies on magnetic structural-phase analysis. Part II deals with the application of structure-insensitive magnetic characteristics to qualitative and quantitative phase analysis. Phase analysis procedures are discussed. Applications of nondestructive testing devices desi…
The ternary chalcogenides AgInSe2 and AgInTe2 were studied by X-ray powder diffraction structure refinement using the Rietveld method. Both compounds crystallizes with a chalcopyrite structure in the space group I 4 2d (N° 122), Z = 4, and unit cell parameters a = 6.0988(2) A, c = 11.7086(6) A, V = 435.51(3) A 3 for A…
El mejor conocimiento de las relaciones que sostienen entre si los atomos dentro de las moleculas ha abierto la posibilidad de la manipulacion directa de los mismos, y con ello, la obtencion de nuevos materiales. Las nanociencias y las nanotecnologias se perciben entonces como herramientas imprescindibles para afronta…
Bi(Zn0.5Ti0.5)O3 (BZT)-modified Pb(Zr(1-x)Ti(x))O3 (PZT) single crystals have been grown using a top-seeded solution growth technique and characterized by various methods. The crystal structure is found to be rhombohedral by means of X-ray powder diffraction. The composition and homogeneity of the as-grown single crys…
Graft copolymerization of acrylonitrile onto torch ginger cellulose was carried out in an aqueous medium with ceric ion redox initiator. The optimum grafting parameters such as temperature, reaction time, ratio of monomer to cellulose addition and ceric ammonium nitrate (CAN) concentration were determined and a maximu…
A combination of thermal analysis (differential scanning calorimetry DSC) and mass spectrometry (MS) has been proposed to estimate the molecular weight (MW) of fluorinated plasma polymers, not reachable by MS only owing to their high dispersity. A noticeable crystalline index has been previously reported for these pla…
In this paper authors present a novel voltage measuring system that allows to measure the voltage of each cell for series connected supercapacitors (SCs). Proposed system is based on isolated DC/DC converter with multiple outputs that have equal voltages, which serve as reference voltage for each series connected supe…
The influence of solvating power of medium on self-organization of metallophthalocyanines in solution is studied. It is shown that phthalocyanine macrocycles form H-associates in universal solvation medium. In case of specific solvation the nature of peripheral substitution of phthalocyanine macrocycle plays important…
Ba0.85Ca0.15Ti0.9Zr0.1O3 (abbreviated as BCTZ) lead-free piezoelectric ceramics co-doped with Li2CO3(0.6 wt.%) and different Co ion content (x = 0, 0.25, 0.4, 0.6, 0.8 wt.%) were prepared by conventional solid state reaction method. Influence of Co ion doped amount on the phase structure, microstructure, piezoelectric…
The regular structure of superconducting nanoislands of alloy W-Ga-C was fabricated on nanothin graphite using focused ion beam. The resistance vs temperature dependence down to 1.7K and the magnetoresistance in field up to 24T were measured both for the bridge containing nanoislands and for the reference bridge witho…
Summary form only given. Single-wall semiconducting carbon nanotube (CNT) field-effect transistors (CNFETs) have been among the foremost candidates to complement Si and extend CMOS technology scaling to sub-10-nm technology thanks to the atomically thin body of CNTs and their near-ballistic transport [1-3]. However, n…
We report NPI as a flexible dielectric for transistors based on 2D atomic sheets such as graphene and MoS2, which features high mechanical flexibility, stable electrical performances and low roughness. NPI offers the realistic prospects for highly flexible electronics beyond the typical 2% limitation of high-κ or cera…
