Ferroelectric materials are used in actuators or sensors because of their non-volatile macroscopic electric polarization. GeTe is the simplest known diatomic ferroelectric endowed with exceedingly complex physics related to its crystalline, amorphous, thermoelectric, and—fairly recently discovered—topological properti…
Low defect smooth substrates are essential to achieve high quality diamond epitaxial growth and high performance devices. The optimization of the Ar/O2/CF4 reactive ion etching (RIE) plasma treatment for diamond substrate smoothing and its effectiveness to remove subsurface polishing damage are characterized. An O2/CF…
Abstract BACKGROUND Bio‐oils can be effectively used for the preparation of bio‐based materials owing to their chemical compositions. In this study, brown macroalgal‐derived bio‐oil was used for the synthesis of graphene oxide‐carbon dot composite by a simple hydrothermal process. RESULTS A simple and facile hydrother…
Abstract Organic ferroelectrics have been actively developed with the goal of fabricating environmentally friendly and low‐cost memory devices. The remanent polarization of hydrogen‐bonded organic ferroelectrics approaches that of the inorganic ones. Nanoscale fabrication of organic ferroelectrics is an essential aspe…
In this paper, a triple-band terahertz metamaterial absorber (MA) based on buck Dirac semimetals (BDSs) is proposed, which consists of a windmill-shaped element in a square ring layer, a dielectric layer, and a BDSs layer. The MA unit cell is investigated at normal and oblique incidence angle for both transverse elect…
• A network-structured layer is formed by nanoparticles in the pyrolysis process. • The properties of the layer are important in determining flame retardancy. • The layer plays a competing role in determining overall transport characteristics. • Carbon nanotubes are more effective than nanoclays in reducing flammabili…
In recent years, increasing attention has been paid to the origin, transmission and communication of silk. However, this is still an unsolved mystery in archaeology. The identification of silk-producing species, especially silk produced by Bombyx mori (B. mori) and Antheraea pernyi (A. pernyi), is of key significance…
In this research, the purpose is to study the solid–liquid equilibrium solubility of pymetrozine and the influence of the solvent effect on solubility. The solubility of pymetrozine was measured by using a static equilibrium method. The solubility of pymetrozine increases with increasing temperature, and the solubilit…
Obtaining crystals and solving the phase problem remain major hurdles encountered by bio-crystallographers in their race to obtain new high-quality structures. Both issues can be overcome by the crystallophore, Tb-Xo4, a lanthanide-based molecular complex with unique nucleating and phasing properties. This article pre…
We report direct evidence of the theoretically predicted electron-rich surface of doped perovskite manganites ${\mathrm{La}}_{0.7}{A}_{0.3}{\mathrm{MnO}}_{3}\phantom{\rule{4pt}{0ex}}(A=\text{Ca}$, Sr) by means of surface-enhanced Raman spectroscopy. The required Au nanoparticles were grown on top of thin manganite fil…
Doping of two-dimensional materials provides them tunable physical properties and widens their applications. Here, we demonstrate the postgrowth doping strategy in monolayer and bilayer tungsten disulfide (WS 2 ) crystals, which utilizes a metal exchange mechanism, whereby Sn atoms become substitutional dopants in the…
Abstract With a combination of outstanding properties and a wide spectrum of applications, graphene has emerged as a significant nanomaterial. However, to realize its full potential for practical applications, a number of obstacles have to be overcome, such as low-temperature, transfer-free growth on desired substrate…
Incapability of effective cross-talk with biological environments has partly impaired the in vivo functionality of nanoparticles (NPs). Homing, biodistribution, and function of NPs could be engineered through regulating their interactions with in vivo niches. Inspired by communications in biological systems, endowing…
In this study, Na + Montmorillonite (C Na), Nanoclay 1-135 (C 10A) and Nanoclay 1-140 (C 15A) were used as nanofiller in the preparation of chitosan biopolymer/clay nanocomposites. For this purpose, a dilute acetic acid solution was used as solvent for dissolving and dispersing the chitosan and the clays, respectively…
Microstructures (MSs) of gallium oxide were synthetized via vapor-solid mechanism using the hydrogen-assisted chemical vapor deposition (HACVD) technique, without the aid of a carrier gas which is part of the usual CVD synthesis recipe. Deposition temperature was varied to investigate its influence on the structural,…
This article shows that the spin-to-charge current conversion in single-layer graphene (SLG) by means of the inverse Rashba-Edelstein effect (IREE) is made possible with the integration of this remarkable 2D material with the unique ferrimagnetic insulator yttrium iron garnet ($\mathrm{YIG}={\mathrm{Y}}_{3}\mathrm{F}{…
Bacterial biofilm on medical devices is difficult to eradicate. Many have capitalized the anti-infective capability of silver ions (Ag+) by incorporating nano-silver (nAg) in a biodegradable coating, which is then laid on polymeric medical devices. However, such coating can be subjected to premature dissolution, parti…
In this work, high-performance ultraviolet to long-wave infrared (UV–LIR) devices based on an N-type three-dimensional (3D) Dirac semimetal Cd 3 As 2 and P-type organic (small molecules and polymers) heterojunction are prepared. Primarily, the photodetector shows a broadband photoresponse from 365 to 10600 nm. The opt…
Abstract The control of the density and type of line defects on two-dimensional (2D) materials enable the development of new methods to tailor their physical and chemical properties. In particular, mirror twin boundaries (MTBs) on transition metal dichacogenides have attracted much interest due to their metallic state…
Ground tire rubber (GTR) was processed using an auto-thermal extrusion as a prerequisite to green reclaiming of waste rubbers. The reclaimed GTR underwent a series of tests: thermogravimetric analysis combined with Fourier-transform infrared spectroscopy (TGA-FTIR), scanning electron microscopy (SEM), Fourier-transfor…
