In this study, dielectric constant and pyroelectric current measurements under high pressure up to 16.7 kbar have been performed for the interacting spin dimer system ${\mathrm{TlCuCl}}_{3}$, which exhibits spin-driven ferroelectricity in the magnon Bose-Einstein condensation (BEC) phase with strong quantum spin fluct…
An active pharmaceutical ingredient may exist in different solid forms, which are the products of the variation of molecular conformation and packing order stabilized through different intermolecular interactions. Two special conditions, tautomerism and amphoterism, will make the solid-state landscape more abundant an…
Using the two-dimensional recurrence relations of X-ray dynamical diffraction, a numerical simulation of reflection and transmission intensity in a cylindrical crystal has been performed. It is shown that for crystals with a small radius Bragg diffraction is realized. For crystals of large radius, Bragg–Laue diffracti…
Penelitian ini dimaksudkan untuk studi karakteristik campuran AC-BC berdasarkan limbah kantong plastik sebagai bahan tambah. Pencampuran dilakukan dengan menambahkan potongan plastik pada campuran aspal berdasarkan cara kering. Metode dalam penelitian ini adalah melakukan serangkaian pengujian karakteristik agregat ka…
Undoped ZnO and Ag-doped ZnO were prepared to use as near-infrared (NIR) shielding by simple precipitation method with zinc acetate and zinc nitrate as Zn precursor and silver nitrate as Ag precursor. The Ag-doped ZnO and undoped ZnO were characterized by XRD, SEM, and UV-vis-NIR spectrophotometer. The NIR reflectance…
Improvement of the physical and mechanical properties of hard alloys based on WC – Co widely used in manufacturing of structural and tool products nowadays results from the use of novel technologies providing formation of a homogeneous high-density structures. Slight deviations of the carbon content from the equilibri…
By using synchrotron radiation photoemission, this study investigates the room-temperature surface electronic structure of Si 1− x Ge x (001)-2 × 1 grown by molecular-beam epitaxy on an epi Ge(001) substrate. The electronic structure of the Ge content, which ranges from 10% to 90%, shows similar surface behaviors. The…
To obtain the appropriate mechanized cutting region for banana dehanding, the methods of X-ray Computed Tomography (CT), Paraffin-embedded tissue section, and scanning electron microscopy (SEM) were adopted to observe the morphological and anatomical characteristics of vascular bundles of the banana crown. The results…
A TE-pass polarizer based on multiple hybrid plasmonic waveguides (HPWs) is proposed, where the polarizer section consists of four symmetrically placed HPWs and a single-mode silicon waveguide in between. Owing to the strong polarization-dependent absorption loss of the multiple HPWs, the unwanted TM polarized light i…
Biomass has increasingly proven as a sustainable and important resource for the production of renewable fuels worldwide. The present study investigated the effect of cellulosic binders on thermal and resistive properties of biofuel briquettes produced from sugarcane bagasse. Biofuel briquettes were produced using an u…
Abstract Donor‐acceptor (D−A) frameworks have been produced via the copolymerization of the strong donor dithieno[3,2‐b:2′,3′‐d]pyrrole (DTP) with ambipolar thieno[3,4‐b]pyrazine (TP) units to generate soluble, processible materials with band gaps as low as 0.8 eV. Optical and electronic characterization of the DTP‐TP…
Obtaining the constant force at a given current benefits its applications in diverse fields. However, not depending on displacements, such a force characteristic is not available easily since this force is determined by a specific structure, materials, geometrical parameters and others. Therefore, utilizing the finite…
A series of metal element (Al, Fe, Mg and Ni)-doped ZnO (M-ZnO) photocatalysts have been successfully synthesized on graphene-coated polyethylene terephthalate (GPET) flexible substrate via the hydrothermal method. The effects of doped metals in ZnO were also studied on the crystal structure, morphology and photocatal…
Multiphase microstructures containing film‐like carbon‐enriched austenite and martensite matrix represent an ideal microstructure that can facilitate the breakthrough of the trade‐off between strength and toughness, as well as good low‐temperature toughness in high‐strength steels. In this study, to determine the impa…
Abstract Microporous activated carbon (MAC) was synthesized from winemaking waste and was used to adsorb Mn(VII) from aqueous solutions under various experimental conditions. Moreover, Mn(VII) adsorption on MAC was compared to other adsorbents and an ion‐exchange resin, as well as those of other anionic complexes. Lan…
Many heteroacenes have been extensively studied to improve device performances; however, the morphological effects stemmed from the chemical modification on a multiscale remain less explored. In this research, five axisymmetric S,N-heteropentacenes ( DTPT, DTPT-Ph, DTPT-CN, DTPT-PYCN, and DTPT-BTCN ) are studied to re…
The purpose of the present work was to study the corrosion protection that relatively low-cost magnesium hydroxide coatings offer to concrete by stabilizing the surface pH. To facilitate the material’s adhesive ability, methyl-cellulose and carboxymethyl-cellulose were used as environmentally friendly additives in thr…
The asymmetric propagation of mechanical energy across interfaces is a challenging problem with a wide range of applications. In this work, we present a novel structure presenting the asymmetric propagation of elastic waves in thin plates in a broadband range. The structure consists of a combination of symmetrically a…
We have developed two series of p-type conjugated polymers based on poly[2,3-bis-(3-octyloxyphenyl)quinoxaline-5,8-diyl-alt-thiophene-2,5-diyl] (TQ1) polymeric backbone utilizing polar pendant groups, i.e. tertiary amine and pyridine, to achieve switchable solubility in water and ethanol. By balancing the ratio betwee…
