Glancing angle deposition (GLAD) of AlN nanostructures was performed at room temperature by reactive magnetron sputtering in a mixed gas atmosphere of Ar and N2. The growth behavior of nanostructures shows strong dependence on the total working pressure and angle of incoming flux. In GLAD configuration, the morphology…
The effect of multi-pass MAG welding transfer modes on the sigma phase precipitation and corrosion performance of AISI 316L thick plate were investigated. The evolution of the microstructure was examined by optical and electron microscopy as well as ferritscope measurements and energy dispersive X-ray spectrometry. An…
Abstract We have prepared reduced graphene oxide-CoFe2O4/FeCo nanocomposites with tunable and excellent absorbing properties through a simple one-step hydrothermal method. The obtained nanocomposites show magnetic particles with a diameter of ∼40 nm that are homogeneously wrapped by ∼5 nm thick graphene layers. Benefi…
The successful development of tablet formulations of many active pharmaceutical ingredients (APIs) is challenged by their poor manufacturability (e.g., flowability, tabletability) and dissolution characteristics. Here, we report a novel quasi-emulsion solvent diffusion cocrystallization (QESD-CC) method as an integrat…
We propose novel quantum antennas and metamaterials with a strong magnetic response at optical frequencies. Our design is based on the arrangement of natural quantum emitters with only electric dipole transition moments at distances smaller than a wavelength of light but much larger than their physical size. In partic…
Abstract Photoassisted steam reforming and dry (CO2) reforming of methane (SRM and DRM) at room temperature with high syngas selectivity have been achieved in the gas‐phase catalysis for the first time. The catalysts used are bimetallic rhodium–vanadium oxide cluster anions of Rh2VO1–3−. Both the oxidation of methane…
The attention to renewable materials is amazingly increased in recent years to decrease environmental pollutions. Zea mays (corn) is one of the most produced plants by humans to provide food and energy. Hence, corn wastes as abundant and low-cost biomass are easily found throughout the world. Tremendous efforts have b…
Biodegradable and biocompatible polyhydroxyalkanoates (PHAs) are promising alternatives to conventional plastics. Based on the chain length of their monomers they are classified as short chain length (scl-) or medium chain length (mcl-) PHA polymers. The type of monomers, the composition and the molecular weight (MW)…
The densification behavior and mechanical properties of spark plasma sintered titanium-molybdenum alloys were investigated in this paper. All Ti-(4, 8, 12, 16, and 20 wt%) Mo samples were sintered at 1200 °C for 5 min under 50 MPa. A significant relative density of 99.9% was secured for the Ti-based alloy with 16 wt.%…
Abstract For wider‐band and stronger electromagnetic (EM) wave absorption, macroporous short carbon fibers/mullite matrix (C f /Mu) composites were prepared via introducing short carbon fibers (0, 0.7, and 1.3 vol%) with length of 2‐3 mm into macroporous mullite ceramic by gel‐casting. The density of as‐prepared C f /…
Two hourglass-type molybdophosphate hybrids with the formulas [Cd(H 2 O) 2 DABT] 4 [Cd(H 7 P 4 Mo 6 O 31 ) 2 ]·19H 2 O ( 1 ) and (C 2 H 5 OH)(C 3 H 5 N 2 ) 6 [Co 3 (H 6 P 4 Mo 6 O 31 ) 2 ]·H 2 O ( 2 ) (DABT= 3,3′-diamino-5,5′-bis(1H-1,2,4-triazole)) have been successfully designed and synthesized via a hydrothermal me…
We theoretically propose a simple ultra-narrow multi-band perfect absorber for sensing applications. The perfect absorber consists of periodically arranged metallic nanodisks etched with regular prismatic holes standing on the dielectric-metal bi-layer films. Multiple ultra-narrow perfect absorption bands are obtained…
High-pressure chemistry is an interdisciplinary science which uses high-pressure experiments and theories to study the interactions, reactions, and transformations among atoms or molecules. It has been extensively studied thus far and achieved rapid development over the past decades. However, what is next for high-pre…
Temporally controlled cooperative and living supramolecular polymerization by the buffered release of monomers has been recently introduced as an important concept towards obtaining monodisperse and multicomponent self-assembled materials. In synthetic, dynamic supramolecular polymers, this requires efficient design s…
Abstract An unprecedented type of electronically conjugated porous covalent organic framework (COF) is synthesized for specific use in the electrode materials of electro‐ionic soft actuators. Because the basic structure contains most of the electron‐rich nucleophilic heteroatoms found in the periodic table with high p…
The world’s food supply is produced from a finite area of land. Chitosan’s bioactivity comes from a complex amine molecule that carries a positive charge. Physiologically, plants grown from seeds that have been implanted with chitosan are more productive compared with plants grown from untreated seeds. The literature…
Si-rhodamine has been extensively used in super-resolution fluorescence imaging in recent years. Its equilibrium between ring-closed nonfluorescent spirolactones and ring-opened fluorescent zwitterions endows Si-rhodamine with excellent fluorogenicity, membrane permeability, and photostability. In this paper, the equi…
Abstract Pressure-induced structural changes in metallic glasses have been of great interest as they are expected to open new ways to synthesize novel materials with unexpected properties. Here, we investigated the effect of simultaneous high-pressure and high-temperature treatment on the structure and properties of a…
In order to study the flame retardant properties of hydroxylated multi-walled carbon nanotubes (MWCNTs-OH) modified barium phenolic resin (PR), MWCNTs-OH modified PR composites was prepared by in situ polymerization method. Thermal stability and flame retardancy of PR composites were studied by oxygen index (OI), ther…
Color plays an important role in human life: without it life would be dull and monochromatic. Printing color with distinct characteristics, like hue, brightness and saturation, and high resolution, are the main characteristic of image sensing devices. A flexible design of color filter is also desired for angle insensi…
