A simple and universal strategy for easily controllable, reproducible and color-stable white organic light-emitting diodes (WOLEDs) utilizing a single-emitting-layer consisting of two complementary nondoped emitters with blocked energy transfer is demonstrated. The device efficiencies achieve 3.64 cd/A and 3.81 lm/W,…
DC power systems, such as DC microgrids, DC datacenters, and HVDC systems, are emerging technologies in recent years. Short circuit current calculation is essential to study the protection and safety issues for DC systems. The time domain simulation for detailed fault analysis contains detail dynamic system models wit…
Translation of stem cell therapies to clinical stage requires viable delivery vehicles that can control stem cell behavior. In this study, the suitability of gelatin microspheres (GMs) as such a tissue engineering platform for human adipose derived stem cells (ADSCs) is investigated. ADSCs on GMs, show a significant u…
Many proteins, including cytochrome c (cyt c), have been shown to form domain-swapped oligomers, but the factors governing the oligomerization process remain unrevealed. We obtained oligomers of cyt c by refolding cyt c from its acid molten globule state to neutral pH state under high protein and ion concentrations. T…
Polymer solar cells with enhanced initial cell performances and long-term stability were fabricated by performing a simple dry transfer of a hole extraction layer [poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS)] onto an indium tin oxide (ITO) substrate. Due to the very flat surface of the polyuret…
A laser ablation technique is applied for synthesis of silver nanoparticles in different concentrations of polyvinyl alcohol (PVA) aqueous solution. The ablation of high pure silver plate in the solution is carried out by a nanosecond Q-switched Nd:YAG pulsed laser. X-ray diffraction and transmission electron microsco…
The time development of the polysaccharide content in the wood residue and the black liquor during kraft pulping for softwood is the focus of this study. The degradation process falls into two distinct categories: the chain element type and the chain fragment type. In the chain element reactions, a single element in t…
Frequency Selective Surfaces (FSS) have long been used in the RF/microwave community to control radar cross-section. The scattering parameters of the FSS form a signature which is a function of the frequency, element size and spacing, as well as the local electromagnetic environment. This paper considers a FSS as a st…
Abstract An iridium(III) complex comprising three different cyclometalated phenylpyridine‐based ligands was designed and synthesized. Interestingly, mixed‐ligand complexes could be obtained by using a simple and straightforward procedure. A tris(heteroleptic) IrIII complex was obtained as a mixture of stereoisomers th…
Dark mode which is subradiant plays a key role in the generation of Fano effect. This study proposes that plasmon interaction between dark modes is a favorable method to generate multiple Fano resonances, where plasmon hybridization leads to the formation of a subradiant bonding and a subradiant antibonding combinatio…
BACKGROUND: A new multisource phase-controlled radiofrequency (MPCRF) device is widely used for skin tightening and rejuvenation in Asia. OBJECTIVE: To evaluate the efficacy of MPCRF objectively and histologically. METHODS: An MPCRF device with real-time impedance control was evaluated. Ten Japanese patients were trea…
Tribological characteristics of ultrahigh-molecular-weight polyethylene (UHMWPE)-based compositions with graphite and molybdenum disulfide are studied under conditions of dry friction, boundary lubrication, and abrasive wear. It is shown that, under dry sliding friction, the wear rate of UHMWPE-graphite and UHMWPE-MoS…
The structure and superplasticity characteristics of the Al-Zn-Mg-Cu-Ni-Zr alloys with different amounts of Zn and Mg have been analyzed. It has been demonstrated that for the formation of a micrograined structure and superplasticity effects, a bimodal size distribution of particles is required, i.e., the presence of…
The results of studies of thermal expansion of the sintered beryllium oxide in the temperature interval 20–1550°C are presented. Measurements were performed by a dilatometric method on a DIL-402C set-up manufactured by NETZSCH (Germany), with the accuracy of (1.5–2) × 10 −7 K −1 . Approximation dependences of coeffici…
Comparison of the photocatalytic and photoluminescence properties of zinc oxide lightly doped with copper and manganese shows that the relationship between these two processes is due to several reasons, the most important of which are the crystalline state of the material and the type and concentration of the modifier…
BACKGROUND: Secondary structures prediction of proteins is important to many protein structure modeling applications. Correct prediction of secondary structures can significantly reduce the degrees of freedom in protein tertiary structure modeling and therefore reduces the difficulty of obtaining high resolution 3D mo…
The mathematical formulation of the heat-input-controlled vapor bubble growth in an infinite volume of uniformly heated liquid is described. Using the dimensional theory, the structure of the solution was analyzed qualitatively. A historical survey of theoretical works devoted to the considered problem is presented. A…
Unraveling structural dynamics of noble metal nanoclusters on oxide supports is critical to understanding reaction process and origin of catalytic activity in heterogeneous catalysts. Here, we show that aberration-corrected scanning transmission electron microscopy can provide direct atomic-resolution imaging of surfa…
Recent progresses in magnetic tunnel junctions with perpendicular magnetic anisotropy (PMA) are reviewed and summarized. At first, the concept and source of perpendicular magnetic anisotropy (PMA) are introduced. Next, a historical overview of PMA materials as magnetic electrodes, such as the RE—TM alloys TbFeCo and G…
The toxicity and the internalization, adhesion, and dispersion behavior of manufactured polystyrene latex (PSL) nanoparticles (nominal diameter: 50 nm) with various functional groups toward the yeast Saccharomyces cerevisiae (which was applied as a model eukaryote) were examined using the colony count method, and micr…
