We study the phase transition in Cu-substituted iron-based superconductors with a new developed real-space Green's function method. We find that Cu substitution has strong effect on the orbital-selective Mott transition introduced by the Hund's rule coupling. The redistribution of the orbital occupancy which is caused…
ABSTRACT Two reactive dyes (P1 and P2) based on salicyladehyde‐4‐amino‐benzoylhydrazone, which show high sensitivity and selectivity in sensing Zn2+, were synthesized and used to modify nonwoven silk fabrics. The prepared silk fabric was then characterized by IR, UV‐Vis, and fluorescence measurements. The results show…
We use density functional computations to study the zero temperature structural, electronic, magnetic, and optical properties of (5,0) finite carbon nanotubes (FCNT), with length in the range of 4–44 Å. It is found that the structural and electronic properties of (5,0) FCNTs, in the ground state, converge at a length…

The magnetic properties of CoP electrodeposited alloys can be easily controlled by layering the alloys and modulating the P content of the different layers by using pulse plating in the electrodeposition process. However, because of its amorphous nature, the study of the interface quality, which is a limitation for th…
Molecular beam epitaxy growth and basic physical properties of quaternary AlInGaN layers, sufficiently thick for construction of electron blocking layers (EBL), embedded in ternary InGaN layers are presented. Transmission electron microscopy (TEM) measurement revealed good crystallographic structure and compositional…
Multifunctional nanoplatforms were prepared via floating self-assembly using a hard nanoparticle (NP) as the core and a modified-polymer (MP, cholesterol-chitosan linked with polyethylenimine) droplet as the shell in a single-pass aerosol nanoencapsulation process. The floating hard NPs (silica, calcium carbonate, gol…
With the growing demand for measurements of organophosphate (OP) pesticide use in agriculture along with the potential threat of OP‐based chemical warfare agents, there is a need for new devices or surfaces that can quickly degrade OPs into less toxic substances in a variety of environments. Using surface‐initiated at…
This paper presents a simple novel crash energy absorbing system made of plain aluminium thin-walled tubes and honeycomb. The proposed tube/honeycomb system is characterized by slightly shorter tubes inserted into the cells of the honeycomb with close fit. The individual tube and honeycomb structures are numerically m…
Green nanotechnology is an eco-friendly approach for the synthesis of metal nanoparticles and a promising alternative for chemical methods. In this study, we have synthesized zinc nanoparticles by utilizing the leaf extract of the plant Cestrum nocturnum as a reducing agent. The generated nanoparticles were characteri…
ABSTRACT Catalytic thermal cleavage of thiocarbonylthio end‐groups for RAFT synthesized polymers is usually accompanied by other side reactions such as chain‐scission and crosslinking. Occurrence of these side reactions depends on polymers, end‐groups, and oxidation–reduction property of reaction media in a liquid pha…
Topological crystalline insulators are a class of materials with a bulk energy gap and edge or surface modes, which are protected by crystalline symmetry, at their boundaries. They have been realized in electronic systems: in particular, in SnTe. In this work, we propose a mechanism to realize photonic boundary states…
We have studied the temperature and field dependences of electrical resistivity and heat capacity of TbFe2Al10, and have also complimented the above studies with low field magnetization measurements. In zero magnetic field, TbFe2Al10 exhibits paramagnetic (PM) to ferrimagnetic (Ferri-I) and Ferri-I to antiferromagneti…
Dalam penelitian ini dilakukan uji kekerasan dan keausan tepi dari dua jenis pahat HSS yakni produk buatan China dan Jerman yang diperoleh di pasar (common market). Metode pengujian kekerasan menggunakan Brinell dan pengukuran keausan tepi VB memanfaatkan bantuan software CorelDRAW X4 dengan skala 0,1 mm. Bahan (raw m…
Sulfonated poly(ether sulfone)/poly(vinylidene fluoride) (SPES/PVDF) blends are prepared and employed as the separator for vanadium redox flow battery (VRB) to evaluate the vanadium ions permeability and cell performance. The SPES/PVDF membranes exhibit dramatically vanadium ions permeability and cell performance comp…
Abstract Diels–Alder reaction of cyclic biphenylylene–acetylene compound 3 with tetraphenylcyclopentadienone (5) realized the preparation of large-sized cyclic polyphenylene array 4. This is the first example of a cyclic polyphenylene array with a complete ring arrangement of a chiral-type CNT segment with (12,3)-stru…
ABSTRACT The birefringence and turbidity of a polystyrene/poly(methyl methacrylate) (PMMA) blend, with the concentration of the PMMA dispersed phase ranging up to 1%, were measured in both a slit channel with a constant cross section and a planar hyperbolic contraction/expansion (8:1:8). The measurements were performe…
Abstract The interfacial atomic structure of an AlN thin film on a nonpolar 4H-SiC( <?CDATA $11\bar{2}0$?> ) substrate grown by atomic Al and N plasma deposition was studied by photoelectron diffraction and spectroscopy. The epitaxial growth of the thin film was confirmed by the comparison of element-specific photoele…
We present the design, construction and test of an automated electronic controller for a Langmuir plasma probe. The novel aspect of this system lies in the isolation of the high voltage present in the discharge from the grounded reference of the controller. This controller detects currents over the range from ±1 μ A t…
