Zn(II) octakis(4-fluorophenyl)tetraazoporphyrin and Cu(II) octakis(4-fluorophenyl)tetraazorphorphyrin were synthesized by the cyclization of bis(4-fluorophenyl)maleonitrile with zinc(II) and copper(II) chlorides. The geometry of Zn(II) octa(4-fluorophenyl)tetraazaporphyrin was optimized by the BioCharmm molecular mech…
We have derived the optical selection rule of monolayer transition metal dichalcogenide (TMD) for various optical vortices. Monolayer TMD, which is two-dimensional direct semiconductor, has a twofold valley degree of freedom. The valley degree of freedom can be controlled by circular polarized light. However, it is no…
A comprehensive analysis of optical and dielectric properties of a material is very much essential for the research of device fabrication. From this perception, the sodium (Na) doped lanthanum manganite with 15% substitution of La by Na (La0.85Na0.15MnO3) has been synthesized using the flux method and investigated to…
Abstract Antibacterial properties of nano-chitosan used for fish preservation would achieve optimum effect when combined with cooling. Applying nano-chitosan incorporated in ice can reduce the cooling cost of conventional fish industry. On the other hand, during fish handling, nano-chitosan has a high probability to b…
Herein, we describe the multi-step synthesis and characterization of monodisperse cubic-structured nanocrystalline diamond particles, showing that they can be easily prepared from graphite flakes under ambient conditions. The above synthesis features the conversion of graphite flakes into graphene oxide (via a modifie…
Recent studies proved that Ferrite Core (FC) power inductors working in sustainable saturation conditions can enable the achievement of switch-mode power supplies with high power density levels. Since the saturation characteristic of these magnetic components is strongly non-linear, mathematical models capable of repr…
It is challenging to prepare polyurethane bioplastics from renewable resources in a sustainable world. In this work, polyurethane nanocomposite bioplastics are fabricated by blending up to 80 wt % of soy-based polyol and petrochemical polyol with hydroxyl-functionalized multiwalled carbon nanotubes (MWCNTs-OH). The sc…
Glycyl-L-Valine (GLV) crystals were grown using distilled water as the solvent at room temperature by solution growth technique. Powder X-ray diffraction confirms the crystalline quality of GLV crystal. The molecular structure of GLV crystal was identified by 13 C NMR spectral studies. The nonlinear optical (NLO) beha…
Abstract The quantum‐size effect, which enables nanographenes to emit photoluminescence (PL) in the UV to visible region, has inspired intense research. However, the control of the PL properties of nanographenes through manipulation of their π‐system by post‐modifications is not well developed. By utilizing a ring‐clo…
We describe our new C-based software that combines atomistic quantum transport with the solution of the 2D Poisson's equation for nanodevice simulation. A significant acceleration of about ~100× is demonstrated in comparison to our old Matlab code, by using numerical libraries BLAS and LAPACK, shared-memory paralleliz…
Abstract Adsorption of hydrogen in four types of activated carbons of different origin with specific micropore volumes ranging from 0.46 to 0.96 cm3/g is studied at temperatures of 303, 313, 323, and 333 K and pressures up to 20 MPa. The saturation adsorption of hydrogen vapors in the considered types of activated car…
Abstract Time-resolved in situ tomography of dendritic growth in Fe–0.45 mass% C carbon steel was performed using synchrotron radiation X-rays at SPring-8 synchrotron radiation facility (Japan) with improvement of the image quality using a physics-based filter. The voxel size of the reconstructed image was approximate…
In this study, the microstructure and mechanical properties of dissimilar austenitic–ferritic stainless steel joints welded by gas tungsten arc welding were investigated. Different offsets of the tungsten electrode's tip from the centerline of the assembled workpieces were used to obtain different elemental melting-mi…
A model for estimating the displacement of a bubble located at a fluid-viscoelastic medium interface in response to acoustic radiation force is presented by extending the model for a spherical object embedded in a bulk material. The effects of the stiffness and viscosity of the viscoelastic medium and the amplitude an…
With synchrotron X-ray phase-contrast computed tomography, we document the wicking process at the fiber scale in cotton, polyethylene terephthalate and polypropylene yarns. A new segmentation procedure is developed, allowing a clear separation of the water and the fiber in the reconstructed images. From the water conf…
High Resolution Image Download MS PowerPoint Slide Here we report on a novel, noninvasive route for operando tailoring of the charge transport properties of metal/WS 2 contacts without the negative impacts to two-dimensional materials arising from conventional doping methods. The doping level of thin WS 2 flakes suppo…
Continuous metalized regenerated cellulose fibers for advanced applications (e.g., multi-functional composites) are produced by electroless copper plating. Copper is successfully deposited on the surface of cellulose fibers using commercial cyanide-free electroless copper plating packages commonly available for the ma…
Abstract—Elastic polyurethanes are flexible materials used in biomedical products. Plasma treatment is a promising method of surface modification. However, external deformation of the elastic substrate could damage the modified layer and provoke various undesirable consequences. In this work, two elastic polyurethanes…
