We propose a general strategy to design planar absorber of excellent absorbing performance using effective medium theory. The method we used can be very useful for the design of planar broadband absorber.
The study of dynamic relaxations in polymer chains has been one of the cornerstones of polymer physics research for over half a century. Increased understanding of polymer chain relaxations has led to the development of macromolecules for packaging, drug delivery and sensor applications. As the challenges for these ap…
A highly conducting and transparent metallic network, on a flexible substrate is obtained by employing the self-cracking technique, combined with the metal electroplating. The self-cracking technique employs a sacrificial film, which cracks, and forms an excellent mask for a subsequent low temperature metal deposition…

First-principles methods are a valuable tool to study the electronic structure of systems and explore the quantum-mechanical mechanisms driving them on the microscopic scale. Semi-local Density-Functional Approximations (DFAs) are still very popular due to the good balance between accuracy and computational efficiency…

With the optimization of the preform structure, the 80μm cladding diameter PMF tensile strength and attenuation could be promoted, the tensile strength test value could reach 23.62 with the attenuation <0.35dB/km @1550nm.
A series of bifunctional catalysts: sulfated zirconia, tungstated zirconia and alumina-supported zirconia as effective supports for Pt was been prepared. The structure and the surface property of denatured zirconium oxide catalysts were characterized by using physico-chemical methods such as XRD, BET, SEM, TEM and TPR…
Generally, JIS type gutter is used in road construction. However, in the case of backfill, there's a possibility that compaction is insufficient when it is using. Therefore a rectangular section gutter was developed by the authors to improve constrains of construction caused by JIS type gutter. However, the range of s…
While the efforts to control global warming are being strengthened all over the world, expectations for CO2 Capture, Utilization and Storage (CCUS) technology for coal fired power plant are increasing. IHI has been working on development of oxyfuel combustion technology since 1989 with the aim of easily capturing and…
The purpose of this document is to describe the measurement campaign with the Free Release Measurement Facility (FRMF) at building 41m “Interim Storage Facility” (ISF) of material clearable according to existing licenses as part of the collaborative research project MetroDecom. \nThe description of the measurement cam…
Conventional strong is solid in compression and weak in strain so as to overcome the fragility diverse sorts of simulated and characteristic strands are utilized to strengthen the pressure conduct of the concrete. Fibers are most generally discontinuous, randomly distributed throughout the concrete matrices. This pape…
A technology of encapsulation of graphene in Parylene was introducedas an alternative to encapsulating graphene in hBN. Edge contacts to theencapsulated graphene in this case showed resistivity down to 14 Ohm um,which is the lowest reported value so far. The resulting graphene devicesshowed a high carrier mobility (up…
We demonstrate a polarization-insensitive silicon nitride metalens that can be designed as large numerical aperture (~0.98) divergent lens with high transmission (~0.8) for visible light, and fabricated using 695 nm thick hexagonal silicon nitride array.
Rotational friction welding is one of the promising technologies for the creation of high-quality welded joints, which is widely used in the pipe industry when producing wide nomenclature drill pipes of medium-carbon alloy steels. Despite the long-term application of this method by the Russian enterprises manufacturin…

We realize −90° to 90° optical rotation with a high efficiency (>0.9) and a high degree of linear polarization (>0.9) over a broad wavelength range (100nm) using a plasmonic metasurface composed of thick L-shaped nanoparticles.
To progress introduction of the renewable energy sources including photovoltaic and wind power facilities, it is necessary to compensate for power fluctuations and supply the stabilized power. A hydrogen electric power storage system has been developed for this issue. The system produces hydrogen using surplus power a…
The aim of this research is to modified and graft poly acrylonitrile to poly amidoxime [A1] for dental fillers, because some of the prepared graft co polymers can be molded to a solid, such as maleicanhydride, itaconic acid, methyl nadic anhydride, acetylchloride. New properties of the substrate of useful derivatives…
