High-performance ultrathin polarizers have been experimentally demonstrated employing stacked complementary (SC) metasurfaces, which were produced using nanoimprint lithography. It is experimentally determined that the metasurface polarizers composed of Ag and Au have large extinction ratios exceeding 17000 and 12000,…
Abstract The synthesis, structure, and magnetic properties of four Dy III coordination compounds isolated as [Dy 2 (LH 2 ) 2 (μ 2 ‐η 1 :η 1 ‐Piv)]Cl ⋅ 2 MeOH ⋅ H 2 O ( 1 ), [Dy 4 (LH) 2 (μ 3 ‐OH) 2 (Piv) 4 (MeOH) 2 ] ⋅ 4 MeOH ⋅ 2 H 2 O ( 2 ), [Dy 6 (LH 2 ) 3 (tfa) 3 (O 3 P t Bu)(Cl) 3 ]Cl 4 ⋅ 15.5 H 2 O ⋅ 4 MeOH ⋅ 5 C…
Abstract The preparation of the iron‐containing SSZ‐39 zeolite is described for the first time through two different synthesis methods: post‐synthetic cation exchange and one‐pot synthesis. The nature and stability of the iron species within the different Fe‐SSZ‐39 materials have been studied through different charact…
Lignin extracted from trees is one of the most abundant biopolymers on Earth. Quinone, a substructure in lignin, can be used for energy storage via reversible redox reactions through absorbing and releasing electrons and protons. However, these efforts have encountered hindrances, such as short life cycle, low cycling…
The polarity of oxide surfaces can dramatically impact their surface reactivity, in particular, with polar molecules such as water. The surface species that result from this interaction change the oxide electronic structure and chemical reactivity in applications such as photoelectrochemistry but are challenging to pr…
Linear aliphatic polyesters are degradable thermoplastic polymers, which can be obtained by ring-opening polymerization (ROP) of cyclic esters through a coordination-insertion mechanism. Aluminum based organometallic complexes have a leading position as efficient catalysts for this polymerization process. Aluminumalky…
The expanded Ti 2 C MXene phase was synthesized from the commercial Ti 2 AlC MAX phase using classical acidic aluminium extraction method. The individual expanded Ti 2 C sheets were characterized by the diameters of between 26 and 61 nm and formed the specific network of slit-shaped pores in the size range of 3–5 nm.…
In this work, the glass forming ability was studied in potassium phosphate glasses with increasing amounts of TiO2 in order to obtain a glass-ceramic with photocatalytic properties. The first studied series has been the binary system (100-x) KPO3-xTiO2. Homogeneous and transparent glasses could be obtained with x vary…
Gadolinium-based contrast agents (GBCAs) are an essential tool in clinical MRI. Millions of doses are administered annually to patients worldwide.1 However, free gadolinium, the basis of GBCAs, is extremely toxic in only small amounts. Gadolinium has an atomic radius similar to that of calcium and can interfere with c…
Abstract The magnetocaloric effect (MCE) is an intrinsic thermal response of all magnetic solids which has a direct and strong correlation with the corresponding magnetic phase transition. It has been well recognized that the magnetic phase transition can be tuned by adjusting applied pressure. Therefore, we perform t…
The work presented draws on new analysis of components removed following the second JET ITER-like wall campaign 2013–14 concentrating on the upper inner divertor, inner and outer divertor corners, lifetime issues relating to tungsten coatings on JET carbon fibre composite divertor tiles and dust/particulate generation…
In this study, the reinforcement effect of different proportions of eggshell/silver (ES-Ag) nanomaterial on the structural and antimicrobial properties of 70/30 poly(butylene-co-adipate terephthalate)/polylactic acid (PBAT/PLA) immiscible blends was investigated. The ES-Ag was synthesized using a single step ball mill…
Lawsonia inermis also known as henna was studied as a corrosion inhibitor for aluminum alloy in seawater. The inhibitor has been characterized by optical study via Fourier transform infrared spectroscopy (FTIR). The FTIR proves the existence of hydroxyl and carbonyl functional groups in Lawsonia inermis . Aluminum all…
This paper analyzes the potential application of graphene in microwave frequency reconfigurable antennas. Two multiband designs, one for wireless fidelity (WIFI), covering the frequency bands of 2.4, 3.6, and 5 GHz, and another for the cellular long-term evolution system, operating the frequency bands of 1.8, 2.5, 2.6…
Abstract Capacitive coupling and direct shuttling of charges in nanoscale plasmonic components across a dielectric spacer and through a conductive junction lead to excitation of significantly different dipolar and charge transfer plasmon (CTP) resonances, respectively. Here, we demonstrate the excitation of dipolar an…
Semiconducting polymers have been widely investigated due to their intriguing optoelectronic properties and their high crystallinity that provides a strong driving force for self-assembly. Although there are various reports of successful self-assembly of nanostructures using semiconducting polymers, direct in situ sel…
The asymmetric transmission of electromagnetic (EM) wave can be fully manipulated by chiral metamaterials, but little can achieve real-time and high efficient tunability due to challenges in practically deployable solutions. Here, we proposed a new scheme for flexibly and dynamically controlling the asymmetric EM wave…
The purpose of this study is firstly to investigate the effect of various treatments on the chemical and morphological properties of the fibers of two xerophyte plants (Doum ‘Chamaerops humilis’ and Diss ‘Ampelodesmos mauritanicus’), in order to improve the adhesion between fibers and cement matrix, secondly the effec…
Densification of oxide glasses at the glass transition offers a novel route to develop bulk glasses with tailored properties for emerging applications. Such densification can be achieved in the technologically relevant pressure regime of up to ~ 1GPa. However, the present understanding of the composition–structure–pro…
In this paper, a green microwave-assisted combustion approach to synthesize ZnO-NPs using zinc nitrate and Citrullus colocynthis (L.) Schrad (fruit, seed and pulp) extracts as bio-fuels is reported. The structure, optical, and colloidal properties of the synthesized ZnO-NP samples were studied. Results illustrate that…
