Duplex stainless steel (DSS) has excellent mechanical properties and corrosion resistance. The excellent performance is due to an approximately equal ratio of ferrite and austenite, 50:50. Influenced by the welding thermal cycle, the ratio of ferrite and austenite shows an imbalance in DSS welded joints, resulting in…
Composites were prepared using [Au(CN)2]− complexes and steroidal alkaloid glycosides (SAGs) from tomato, including hydrophilic sugar and hydrophobic aglycone groups. Supramolecular sheet, tubular and unique structures were obtained, depending on the molecular structure of the SAG. Polymeric [Au(CN)2]−n units in these…
ABSTRACT An unprecedented A‐B‐A type block copolymer electroactive polyurea (EPU) is designed and synthesized with tetraaniline dimer and 1,4‐phenylenediamine via an oxidative coupling, where aniline–nonamer and hexamethylene di‐urea constitute two segments. The EPU was characterized by spectral techniques such as Fou…
Superhydrophobic surfaces (SHSs) require a combination of a nano- or microscale rugosity and a low surface energy. However, SH is easily lost under relatively mild mechanical abrasion. Here, by introducing a mesh layer beneath the SH layer, we develop a method that significantly increases the mechanical durability of…
Alternative composite materials with antibacterial activity have been developed by combining the porosity of carbon materials and the antibacterial activity of half sandwich (cymene)Ru-curcumin complexes. Different types of activated carbon were used, from commercial to synthetic and also ones derived from agricultura…
Abstract 2-nitro-4-methylsulfonylbenzoic acid (NMSBA) can be produced by oxidizing 2-nitro-4-methylsulfonyltoluene (NMST) with air catalyzed by Co/Mn/Br and phosphotungstic acid(HPW) loaded on activated carbon. This paper reports that the catalytic ability of the HPW@C catalyst in the oxidation of NMST to NMSBA can be…
Abstract Metal‐supported solid oxide fuel cells have several advantages, which could potentially increase the overall competitiveness of the technology, compared to their cermet‐supported counterparts. However, surface imperfections and rapid oxidation of the metal supports at operating temperatures are factors that a…
ABSTRACT Structure and properties of polymer compositions based on carbon nanotubes (CNTs) filled epoxy matrix containing fluorosilicone copolymers as additives is discussed. Electrical conductivity and dielectric (microwave) permittivity of the composites can be varied by approximately one order of magnitude without…
In a highly CaCO3 filled compression molded short glass fiber polyester GFRP-BMC composite with high solidification texture angle of 71 ± ∼7 deg with respect to specimen length, Charpy impact strength, auc at both low −79°C (194 K) and high 70°C (343 K) temperatures were apparently increased 69 and 32%, respectively o…
The high energy density (HED) capacitor is the energy storage component in capacitive pulsed power systems. There is an obvious voltage decay phenomenon, when the capacitor is disconnected from the power supply, and the higher the energy density is, the faster the voltage decays. And the voltage maintaining performanc…
Designing metamaterials with near-zero electric permittivity (ENZ) is of great importance for practical applications at optical frequencies, but designs based on traditional approaches are restricted to a narrow range of operating frequencies. The authors invoke the rigorous spectral representation of the effective pe…
We study through a computer experiment, using the restricted path integral Monte Carlo method, a one-component fermion plasma on a sphere at finite, nonzero, temperature. We extract thermodynamic properties like the kinetic and internal energy per particle and structural properties like the radial distribution functio…
A new epilithic Sellaphora (Bacillariophyceae) species from a karst spring of Sardinia is described based on light and scanning electron microscopic observations. Sellaphora gologonica sp. nov. shares similarities with small-celled Sellaphora previously described from Europe and particularly with S. atomoides, S. hafn…
To launch a fusion reactor stably, it is necessary to prepare sufficient amount of tritium by an external tritium source. Tritium production using nuclear reactions by neutron and Li in a high temperature gas-cooled reactor (HTGR) is an attractive method. An important issue is tritium confinement in high temperature c…
with x = 2 and 3 (Dppy = diphenylphosphino-2-pyridine), combining gas-phase photoluminescence and photodissociation with quantum chemical computations. These clusters possess an identical isostructural core made of a hyper-coordinated carbon at their center octahedrally surrounded by six gold ions, and two silver ions…
Liquid-particle aggregates were formed electrostatically using pH-responsive poly[2-(diethylamino)ethyl methacrylate] (PDEA)-coated polystyrene particles. This novel non-contact electrostatic method has been used to assess the particle stimulus-responsive wettability in detail. Video footage and fractal analysis were…
We performed in-situ electrical transport measurements for bilayer graphene grown on SiC(0 0 0 1) substrate, Li-intercalated bilayer graphene, and after that desorbing Li atoms by heating. Bilayer graphene after desorbing intercalated Li atoms showed a higher resistivity and different behavior in magnetoconductance co…
In this paper, dynamic response and energy absorption characteristics of three different types of wood-based biocomposites have been investigated using a split Hopkinson pressure bar (SHPB). Different types of biocomposite panel were produced using a Dieffenbacher hot press with a particular composition of refined cot…
Abstract Fe 65 Co 35 thin films have been deposited on SiO 2 substrates using sputtering technique with different choices of seed layer; Ru, Ni 82.5 Fe 17.5 , Rh, Y and Zr. Best soft magnetic properties were observed with seed layers of Ru, Ni 82.5 Fe 17.5 and Rh. Adding these seed layers, the coercivity of the Fe 65…
This paper presents an efficient wavelet based numerical method for analyzing functional and dynamic crosstalk of CMOS driven coupled copper (Cu) interconnects known as Multi-Resolution Time Domain (MRTD), wherein, the CMOS drivers are modeled using n th -power law model. The performance of the proposed MRTD method is…
