Multiple photosynthetic reaction centres have been successfully constructed using strong supramolecular complexes of free base porphyrin polypeptides with lithium ion-encapsulated C60 (Li(+)@C60) as compared with those of C60. Efficient energy migration and electron transfer occur in the supramolecular complexes.
We derive an effective Maxwell-London equation for entangled polymer complexes under topological constraints, borrowing the theoretical framework from topological field theory. We find that the transverse current flux of a test polymer chain, surrounded by entangled chains, decays exponentially from its centerline pos…
The deformed microstructures of Ni20Cr wires include amorphous GB, crystal GB, edge dislocations, and twins. Edge dislocations exist in GB and grain interiors. Twinning angles is approximately 141° and 146°, respectively.
The corrosion behavior of coated and uncoated Ni/Cu/Ni rare earth magnets was assessed at increasing steps with a multilayering silanization procedure. Magnets’ durability was analyzed in Fusayama synthetic saliva solution in order to evaluate their application in dental field. Corrosion performance was evaluated by u…
In the using of materials, kinds of injury which is sometimes difficult to repair or too costly to repair may appear in the surface and interior, which will shorten the life of the materials. Self-healing technology can be used to improve material reliability and extend the service life, so composite materials with se…
The (quasi-)planar wheel-type structures can be obtained by adding electrons.

We report fabrication and characterization of large-area ultrathin near-infrared light absorbers and scatterers based on a mono-layer of gold nanoparticles laying on top of a dielectric spacer and an aluminum reflector. The nanoparticles are formed through thermal annealing of an evaporated continuous gold film. Throu…
It was reported so far that degradation of varistor voltage of metal-oxide varistors (MOVs) was observed when short-tailed impulse currents such as 4/10µs or 8/20µs impulses were applied, whereas after application of impulse currents having rather long duration such as 2ms rectangular current, degradation of varistor…
We have designed and fabricated a mid-infrared hyperbolic metamaterial composed of alternating A1 2 O 3 and chemical-vapor-deposited graphene. Infrared ellipsometry shows a topological transition from elliptical to hyperbolic dispersion at the wavelength of 7.4 μτη.
The data describing of the light scattering intensity relaxation above the glass transition temperature by boron oxide obtained by using of the temperature jump methods are presented. It is found that the stabilization of the glass at 220℃ resulted in increasing of the anisotropic intensity at the same time the isotro…
Theoretical models of movement of a fast melt metal layer (up to v ∼ 10 m/s) and droplet erosion are developed for power density pulses typical for tokamak plasma edge localized modes (ELM) and disruption. Fast melt metal movement and droplet erosion were shown to be possible only at plasma flow pressure P > 1 atm. Th…
This paper reports kinetic analysis of the main thermoluminescent peak in α-Al2O3:C for irradiation doses as high as 120 Gy and at various heating rates going as low as 0.01 K/s. The dependence of the various methods of kinetic analysis on irradiation dose and/or heating rate has been assessed with respect to the main…
We report the synthesis of a readily curable and degradable resin using an alternating copolymer of maleic anhydride and 2,4-dimethyl-1,3-pentadiene. The anhydride moiety of the alternating copolymer reacted with difunctional compounds, such as diepoxy, diol, and diamine derivatives as the crosslinkers, to produce net…
We have investigated the generation mechanisms of pattern defects in directed self-assembly (DSA) lithography using a simulation method based on self-consistent field theory (SCFT). The SCFT simulation results could reproduce grid defects, which are considered to be a kind of hexagonally perforated lamellar (HPL) meta…

The field of application of discrete-continual finite element method comprises structures with regular (in particular, constant or piecewise constant) physical and geometrical parameters in some dimension (so-called “basic” direction (dimension)). Considering problems remain continual along “basic” direction while alo…
This contribution gives the first results of an ongoing research aiming at developing a new surface treatment technique usinga supercritical nitrogen jet, named Jazolthop, for surface modification. As nitrogen is naturally recycled within air, this new process has a high potential for surface treatment without any che…
This paper is devoted to theoretical foundations and verification aspects of the use of discrete-continual finite elements with triangular cross-section for correct semianalytical structural analysis. Application of L-coordinates, integration schemes, algorithms of computing of local and global stiffness matrices and…
