The directed assembly of conjugated polymers into macroscopic organization with controlled orientation and placement is pivotal in improving device performance. Here, the supramolecular assembly of oriented spherulitic crystals of poly(3-butylthiophene) surrounding a single carbon nanotube fiber under controlled solve…
Direct oxidation of methanol to high value oxygenated chemicals on V 2 O 5 /TiO 2 based catalysts is a green alternative to the commercial methods. But the V–Ti based catalysts are challenged by the relatively low reactivity. Herein, we demonstrated a facile and practicable strategy to directly fabricate hollow struct…
We have investigated the molecular and electronic structure of a TiO 2 -supported oxomolybdate phase upon reduction under methanol or dihydrogen atmosphere. In situ Mo K-edge X-ray absorption spectroscopy, supported by density functional theory (DFT) calculations and ab initio X-ray absorption spectroscopy (XAS) spect…
We report the transmission and reflection properties of graphene-SiO 2 , graphene-Si interface with normal incidence. We analyze the real and imaginary parts of Graphene in a broad wavelength range 0.5–4.0 µm and use both Fresnel theory and Finite-difference Time-domain (FDTD) numerical simulations to calculate the tr…
Abstract The thermo‐degradative behaviour of non‐woven plastics was studied in order to analyze their thermal stability and subsequent recycling method. Non‐isothermal thermogravimetric experiments using wide range of heating rates of 10, 20, 40, 60, 80,100 °Cmin −1 have been performed from ambient to 900 °C in a ther…
Development of chiral quantum dots (QDs) is an emerging field, as these nanomaterials could find a range of potential applications including sensing, imaging, asymmetric catalysis, enantiomeric separation, spintronics, and as a circularly polarized light sources. Here, we report an investigation of optical activity wh…
We study the orientational transitions in a suspension of carbon nanotubes in a nematic liquid crystal induced by an external magnetic field. The case of a finite orientational anchoring of liquid crystal molecules at the surface of doped carbon nanotubes is considered. It is shown that in a magnetic field the initial…
Phosphorus is one of the most important macronutrients for the primary production. The transformation of dissolved organic phosphorus in the environment and its contribution to biological production in the different ecosystems is still a mystery. Recently, it was demonstrated that phosphate ester can be rapidly hydrol…
Mixed-dimensional (2D + n D, n = 0, 1, and 3) van der Waals heterostructures opened new avenues for fundamental scientific studies and applied device designs. We demonstrate the type-II staggered band alignment in WSe 2 /CdSe (2D+1D) van der Waals heterostructures and a distinct enhanced optoelectrical response compar…
The n-type HgCr_{2}Se_{4} exhibits a sharp semiconductor-to-metal transition (SMT) in resistivity accompanying the ferromagnetic order at T_{C}=106 K. Here, we investigate the effects of pressure and magnetic field on the concomitant SMT and ferromagnetic order by measuring resistivity, dc and ac magnetic susceptibili…
Water-based electrospinning offers an attractive alternative to organic solvent- rich electrospinning methods. This is to satisfy both increasing environmental concerns and ensure a higher degree of occupational safety as the process becomes ubiquitous and increasingly scalable in both academic and industrial settings…
An attempt has been made to combine small-angle scattering of X-rays or neutrons with scanning electron microscopy in reciprocal space, in order to establish a structural analysis method covering a wide range of sizes from micro- to macro-scales. A system with a binary contrast, in which scattering objects with a homo…
Abstract In a previous work, a very promising mathematical model for predicting the electrical conductivity below the electrical percolation threshold, for both isotropic and anisotropic composites, was published by Schubert. In this work, periodic boundary condition of the simulation is utilized. The results are also…
This paper proposes novel triangular cross-sectioned geometry of carbon nanotube (CNT) bundles for crosstalk and delay reduction in CNT bundle interconnects for VLSI circuits. First, we formulate the equivalent single conductor (ESC) transmission line models of the interconnects. Through SPICE analysis of the ESC circ…
The van der Waals coupling modulation is a crucial method for designing of the physical performance in bilayer transition-metal dichalcogenides. Here, we report the band evolution and quantum transport properties of twisted bilayer WSe 2 under the approach of vertical electric fields by utilizing first-principles calc…
Abstract Models of deposition and detachment dynamics of different shaped anisotropic colloids are reported to understand how equilibrium deposited amounts compare to spherical colloids. For different shaped colloids including spheres, ellipsoids, toroids, and buckled particles with varying aspect ratios, interaction…
It is expected, the growing demand for supercapacitor energy storage system (ESS) in which thousands of supercapacitor cells are connected as a stack for meeting the desired load power. The lifetime of ESS dramatically depends on the operating thermal effects of individual cells. In this paper, a temperature-suppressi…
Pine cone and Spartium junceum are readily available cellulosic materials which can be used as reinforcements in thermoplastic-based composites. In the present study, flours issued from Pine cone (PCF) and Spartium junceum (SjF) were first chemically modified with maleic anhydride (MA) and silane. Then, neat and treat…
Human guanylate-binding protein 1 (hGBP1) belongs to the family of dynamin-like proteins and is activated by addition of nucleotides, leading to protein oligomerization and stimulated GTPase activity. In vivo, hGBP1 is post-translationally modified by attachment of a farnesyl group yielding farn-hGBP1. In this study,…
ABSTRACT A radiocarbon ( 14 C) activity analysis in the tree rings around Ignalina nuclear power plant (INPP) has been carried out with the aim to test the hypothesis to use 14 C tree-ring analysis data as a tool for the reconstruction of gaseous releases from NPP to the environment. The INPP has been in decommissioni…
