Aiming to address the shortcomings of high-concentration ethanol or methanol extraction solutions that need to be diluted and concentrated prior to use in conventional macroporous resin adsorption approaches, an efficient approach for enrichment and purification of aucubin from the ionic liquid extraction solution of…
ABSTRACT A wide variety of fillers are used in the rubber industry to modify the properties of rubber compounds and reduce the cost of products in different applications. Silica produced from rice husk could be an alternative filler to commercial precipitated silica widely used in sulfur-vulcanized rubber formulations…
Becoming invisible is basically playing with the reflection spectra, where we can either rebuild the original propagating ray traces to cloak an object as if it never existed, or alternatively, conceal the reflected beams by perfectly absorbing all the incidences. In this Letter, a graphene based camouflage metasurfac…
Well-defined sulfonated aniline oligomer (SAO) microstructures with rod and flake morphologies were successfully synthesized using an aniline and oxidant with a molar ratio of 10:1 in ethanol and acidic conditions (pH 4.8). The synthesized oligomers showed excellent dispersibility and assembled as well-defined structu…
We report self flux growth and characterization of FeTe 1-x S x (x = 0.00 to 0.25) single crystal series. Surface x-ray diffraction (XRD) exhibited crystalline nature with growth in (00 l ) plane. Micro-structural (electron microscopy) images of representative crystals showed the slab-like morphology and near stoichio…
We present a perfect UHF metamaterial absorber by combining coupling lines and fractal lines with a very small unit cell. The proposed absorber consists of a surface metal structure and metallic background plane, separated by a dielectric substrate and air. Simulation results show that the absorber has an absorption p…
Abstract Electrical properties of Br-doped SnSe 2 van der Waals (vdW) materials are investigated by synthesizing polycrystalline SnSe 2− x Br x via a solid-state reaction route. From the x-ray diffraction and Raman spectra results, it can be confirmed that Br impurity substitutes well on a Se-site by minimizing the la…
We use molecular dynamics simulations with the ReaxFF-lg potential to model the high pressure pyrolysis of carbon suboxide (C3O2) in mixture with argon as a pressure bath. We show that the reactive simulations catch the experimental behavior of the low-pressure detonation of C3O2 (around 10 bars in shock tube experime…
Crumple-structured two-dimensional MoS2 was evaluated as an essential element for future optoelectronic and stretchable devices owing to its interesting optical properties. This Letter reports the characteristics of the crumpled structure of MoS2 directly layered on a MoS2 sheet by chemical vapor deposition. The crump…
The aim of this study was the analysis of the thermal resistance of upper textile materials combined with leather or textile linings. Following a comparative analysis of the combinations of materials tested, the best insulators werre recommended. Footwear material packages were created on the basis of the analysis of…
It is environmentally friendly to use water-based emulsion instead of the oil when cold drawing Al alloy production. In this research, adopting specially prepared water-based emulsion, contact angles and tribological properties of as-selected multilayer diamond films are clarified. The contact angle on diamond film is…
We report on a fabrication route based on hot embossing lithography to replicate the surface texture of plants into large-area polymeric foils, with a view to developing multifunctional photovoltaic cover layers. Our approach is demonstrated by reproducing the complex texture of rose petals with a high fidelity from t…
Restricting materials informatics to the numerical parameters output from conventional materials modelling software restricts us to a subset of machine learning methods capable of uncovering structure/property relationships and driving materials discovery and design. Presented here is a simple way of converting materi…
In the present work, the transition, magnetocaloric properties, and spontaneous magnetization in MnCo 1− x Cu x Ge compounds were systematically studied. The maximum magnetic entropy change values of 22.4 J kg −1 K and 10.9 J kg −1 K estimated from Landau free-energy scheme under 5 T have been observed at 271 K and 26…
Multiband superconductivity is realized in a plethora of systems, from high-temperature superconductors to very diluted superconductors. While several properties of multiband superconductors can be understood as straightforward generalizations of their single-band counterparts, recent works have unveiled rather unusua…
Eri silk, a wild silk variety available in the northeastern states of India, has better softness, tensile and thermal properties. The present study aimed to develop different knitted structures and investigate the influence of knitting process variables on the thermal comfort and wicking properties. Knitted single jer…
As part of the work, preliminary tests were made of textile materials with bamboo fibres for elements of children’s footwear. The need to expand the range of materials which can be used in children’s footwear is dictated by the specific anatomic structure of the child’s foot during the first years of life. The researc…
We use energy landscape methods to investigate the response of a supercooled liquid to random pinning. We classify the structural similarity of different energy minima using a measure of overlap. This analysis reveals a correspondence between distinct particle packings (which are characterised via the overlap) and fun…
A new design paradigm for the production of low band gap polymers is reported, in which an ambipolar unit exhibiting both donor and acceptor properties is combined with a conventional acceptor. As initial examples of this approach, the synthesis of two alternating copolymers of thieno[3,4- b ]pyrazine and 2,1,3-benzot…
Sodium cobalt oxides (NaCo 2 O[Formula: see text] have attracted considerable attention as promising high-temperature thermoelectric (TE) candidates. In this study, we choose nano-SiC as an inclusion to synthesize NaCo 2 O 4 -based composites using the solid-state method. The crystal structure and TE properties for na…
