Molecules comprised of three covalently linked bi-stable switches can exist in states described by a combination of binary numbers, one for each individual switch: ⟨000⟩, ⟨001⟩, etc. Here we have linked three photo-/thermoswitches together in a rigid macrocyclic structure, one azobenzene (bit no 1) and two dihydroazul…
Perovskite multiferroic oxides are promising materials for the realization of sensitive and switchable photodiodes because of their favorable band gap (<3.0 eV), high absorption coefficient, and tunable internal ferroelectric (FE) polarization. A high-speed switchable photodiode based on multiferroic Bi 2 FeCrO 6 (BFC…
Abstract New device concepts can increase the functionality of scaled electronic devices, with reconfigurable diodes allowing the design of more compact logic gates being one of the examples. In recent years, there has been significant interest in creating reconfigurable diodes based on ultrathin transition metal dich…
We analyzed the conjoint effects of sewage inputs and hydrological alteration on the occurrence of teratological forms and on the assemblage composition of stream benthic diatoms. The study was performed in 11 Mediterranean streams which received treated or untreated urban sewage (Impact sites, I), whose composition a…
A family of Mn III Ln III strictly dinuclear complexes of general formula [Mn III (μ-L)(μ-OMe)(NO 3 )Ln III (NO 3 ) 2 (MeOH)] (Ln III = Gd, Dy, Er, Ho) has been assembled in a one pot synthesis from a polydentate, multipocket aminobis(phenol)ligand [6,6′-{(2-(1-morpholyl)ethylazanediyl)bis(methylene)}bis(2-methoxy-4-m…
The interaction between an edge dislocation and a sessile vacancy cluster in bcc Fe is investigated over a wide range of strain rates from 10^{8} down to 10^{3} s^{-1}, which is enabled by employing an energy landscape-based atomistic modeling algorithm. It is observed that, at low strain rates regime less than 10^{5}…
Extracellular matrix (ECM) provides a dynamic and complex environment to determine the fate of stem cells. In this work, light harvested cell sheets were treated with paraformaldehyde or ethanol, which eventually become ECM. Such ECM was then immobilized on titanium substrates via polydopamine chemistry. Their effects…
Three polyoxometalates (POMs) functionalized by tetrathiafulvalene (TTF) molecules have been synthesized by a coupling reaction between the Anderson-type POMs [MnMo 6 O 18 {(OCH 2 ) 3 CNH 2 } 2 ] 3– or [AlMo 6 O 18 (OH) 3 {(OCH 2 ) 3 CNH 2 }] 3– and the TTF carboxylic acid derivative (MeS) 3 TTF(S-CH 2 -CO 2 H). The m…
Vanadium dioxide exhibits a reversible crystal transition from monoclinic phase to rutile phase, but the quantitative regularity of the effect of particle size on crystal transition thermodynamics still remains unclear. Herein, a new core–shell model was proposed and the universal equations for size-dependent crystal…
Abstract We report the selective fabrication of monolayer TaSe2 with trigonal-prismatic (1H) or octahedral (1T) crystal structure on bilayer graphene by the molecular-beam-epitaxy method. By angle-resolved photoemission spectroscopy, we found that monolayer 1H-TaSe2 shows a metallic electronic structure with a dispers…
We apply classical density functional theory to study how salt changes the microphase morphology of diblock copolymers. Polymers are freely jointed and one monomer type favorably interacts with ions, to account for the selective solvation that arises from different dielectric constants of the microphases. By including…
Layered double hydroxide (LDH) nanoparticles are effective sorbents for selenium oxoanions but must be fabricated in a suitable fashion for implementation in water treatment applications using packed columns. In this work, we demonstrate the preparation of nanocomposite beads prepared from Mg–Al–CO 3 LDH nanoparticles…
Abstract Incorporation of nitrogen functionality onto the high surface area porous polymeric network are very demanding in designing suitable heterogeneous organocatalyst having surface basicity. Here we report the synthesis of a new N ‐rich triazine based microporous organic polymer (TrzMOP) through a simple and effi…
To date, great strides have been made in elucidating the role of thermochemical pretreatments in the chemical and structural features of plant cell walls; however, there is no clear picture of the plant recalcitrance and its relationship to deconstruction. Previous studies precluded full answers due to the challenge o…
One of the highest thermoresistant thermosetting resins ever studied so far, oligosilylarylnitrile resin, was investigated first in this study. Oligosilylarylnitrile was synthesized by lithium-reduced Wurtz–Fittig condensation reaction, and the prepared viscous resin exhibited moderate rheological behaviors while heat…
Breast cancer is the second leading cause of cancer death among women and represents 14% of death in women around the world. The standard diagnosis method for breast tumor is mammography, which is often related with false-negative results leading to therapeutic delays and contributing indirectly to the development of…
Boron is the neighbor of carbon on the periodic table and exhibits unusual physical characteristics derived from electron-deficient, highly delocalized covalent bonds. As the nearest neighbor of carbon, boron is in many ways similar to carbon, such as having a short covalent radius and the flexibility to adopt sp 2 hy…
The refractive index is a basic parameter of materials which it is essential to know for the manipulation of electromagnetic waves. However, there are no naturally occurring materials with negative refractive indices, and high-performance materials with negative refractive indices and low losses are demanded in the te…
Abstract We fabricated (Ba,K)Fe 2 As 2 superconducting wires and tapes using the powder-in-tube method and hot isostatic pressing (HIP). HIP wires and tapes showed a high value of transport critical current density ( J c ) exceeding 100 kAcm −2 at T = 4.2 K and the self-field. Transport J c in the HIP wire reached 38…
Single-phase Fe81Ga19 and dual-phase (Fe0.81Ga0.19)99.95Tb0.05 single crystals with perfect orientation were prepared by directional solidification technology. The performance of the dual-phase single crystal (SC) can achieve 399 ppm in magnetostriction and 10.2% in tensile fracture strain, which are, respectively, 28…
