Firstly, the influence of potassium permanganate-phosphate treatment on surface topography and wettability of AZ31B sheet was studied in this work. Then, the fiber-reinforced resin/magnesium alloy composite laminate was prepared, and its properties were measured. Results showed that the concentration of KMnO4 had a si…
To control the release of the drugs at specific time and location, dual UV- and pH-responsive supramolecular vesicles are described mediated by host–guest interactions. The hydrophobic segment β-CD-Azo-Ace (where β-CD, Azo, and Ace refer to β-cyclodextrin, azobenzene, and acetal, respectively) forms the inclusion with…

Biological activity of aqueous extracts of Pergularia tomentosa L. (Asclepiadaceae). Lebanese Science Journal, 17(1): 27-37. This study focuses on the allelopathic potenti…
The objective of this study was to fabricate dual‐layer hollow fiber as a microreactor for potential syngas production via phase inversion‐based co‐extrusion/cosintering process. As the main challenge of phase inversion is the difficulty to obtain defect‐free fiber, this work focuses on the effect of the fabrication p…
Structure and electronic properties of two-dimensional materials could be tuned by interfacial misfit or orientation angles. However, graphene grown on Ru(0001) substrate usually shows stable moiré superlattice with a periodicity of 3.0 nm indicating an aligned geometry. The reason for the absence of misaligned struct…
We report the deposition of Langmuir–Blodgett (LB) thin films of low-weight dispersed composite systems of ferroelectric liquid crystals (FLCs)–functionalised silver (Ag) nanoparticles. Because of their amphiphilic nature the molecules form stable Langmuir monolayers, which were transferred to silicon substrates. We n…
Abstract Coordinatively unsaturated double‐stranded helicates [(H 2 L) 2 Eu 2 (NO 3 ) 2 (H 2 O) 4 ](NO 3 ) 4 , [(H 2 L) 2 Tb 2 (H 2 O) 6 ](NO 3 ) 6 , and [(H 2 L) 2 Tb 2 (H 2 O) 6 ]Cl 6 (H 2 L=butanedioicacid‐1,4‐bis[2‐(2‐pyridinylmethylene)hydrazide]) are easily obtained by self‐assembly from the ligand and the corre…
Water chlorination is one of the most popular ways of disinfection used in potable water distribution systems. Nevertheless, chlorinated water does influence mechanical properties, structure and characteristics of the surface of plastic water pipes forming the system. This paper presents tests of HDPE and PVC water pi…
A focused helium ion beam was used to introduce nano-sized gap chains in graphene. The effect of beam scanning strategies in the fabrication of the nano-gap chains was investigated. The tuning of graphene conductivity has been achieved by modulating the magnitude and uniformity of the ion dose and hence the morphology…
Abstract Monocrystalline titanium dioxide (TiO 2 ) micro‐spheres support two orthogonal magnetic dipole modes at terahertz (THz) frequencies due to strong dielectric anisotropy. For the first time, we experimentally detected the splitting of the first Mie mode in spheres of radii m through near‐field time‐domain THz s…
Polyhedral gold nanoparticles are of great current interest because of their unique optical and chemical properties which are attributable to their well-defined facets, corners, and size. While various polyhedral gold nanoparticles of different sizes mostly synthesized by the seed-mediated method have been reported, s…

The combination of the two complementary imaging modalities (19) F magnetic resonance imaging (MRI) and fluorescence imaging (FLI) possesses high potential for biological and medical applications. Herein we report the first design, synthesis, dual detection validation, and cytotoxic testing of four promising BODIPY dy…
We report here the design and realization of a broadband, equal-intensity optical beam splitter with a dispersion-free binary geometric phase on a metasurface with unit cell consisting of two mirror-symmetric elements. We demonstrate experimentally that two identical beams can be efficiently generated with incidence o…
The elusive structure of compressed, melt-quenched ${\mathrm{As}}_{2}{\mathrm{Se}}_{3}$ was studied in both its liquid and amorphous form up to $4.4$ and 30 GPa, respectively, by means of x-ray absorption spectroscopy and diffraction. The evolution of the short-range structure is studied by As and Se multiple $K$-edge…
2-Hydroxy-3-(1-naphthyloxy)propyl methacrylate (NOPMA) monomer was synthesized from reaction of 2-[(2-naphthyloxy)methyl]oxirane with methacrylic acid in the presence of pyridine. The polymerization of NOPMA was carried out by free radical polymerization method in the presence of AIBN at 60 °C. The structure of monome…
A well‐controlled three‐step green synthetic method allows the synthesis of composite materials based on the highly stable chromium(III) terephthalate MIL‐101(Cr) with gold nanoparticles (NPs) and polyoxometalates (POMs) inside its mesopores. First, the POM was included within the MIL‐101(Cr) cavities through the dire…
Using state-of-the-art many-body Green's function calculations based on the GW plus cumulant approach, we analyze the properties of plasmon satellites in the electron spectral function resulting from electron-plasmon interactions in one-, two-, and three-dimensional systems. Specifically, we show how their dispersion…
In this study, the electrochemical properties of synthesized intermetallic compounds (IMCs) similar to those commonly found in AA2024-T3 were studied in neutral 0.1 M NaCl at 10, 30, 50, and 70°C using the electrochemical microcell method. Results on the synthesized IMCs were combined with and supported by analysis of…
We report the synthesis and characterization of a family of organometallic cobalt(I) metal precursors based around cyclopentadienyl and diene ligands. The molecular structures of the complexes cyclopentadienyl-cobalt(I) diolefin complexes are described, as determined by single-crystal X-ray diffraction analysis. Therm…
