The plasmonic fields of silver and gold nanocubes are known to be among the strongest of any plasmonic metallic nanoparticles. Aggregation dominates their use in imaging and sensing applications due to the resulting enhancement of the plasmonic field in between the nanoparticles (hot spots). The first step in the aggr…
Bronzes are largely used in various domains such as battery connectors, archaeological artefacts and urban statues, suffering from corrosion process leading to the formation of corrosion products. A protection treatment could be used to insulate them from this environment. In this way we contribute to the protection o…
Tungsten oxide (WO3)-containing glasses of WO3–ZnO–B2O3 were prepared using a conventional melt quenching method, and α-ZnWO4 nanocrystals were synthesized through the crystallization of glasses. A glass with the composition of 20WO3–50ZnO–30B2O3 showed the bulk crystallization of α-ZnWO4 nanocrystals with a diameter…
Chitin was isolated from the shells of Chelonibia patula (barnacle, Crustacea), which lives on blue crab epizoically, following a 10-min demineralisation process through HCl and a 20-min deproteinisation process through NaOH. Due to the low-crystalline structure, and mineral-rich and low-protein content of the shells,…
We have studied the detailed interface structure and energy conversion behavior of TiO 2 /PbS heterojunction solar cells. Nanoscale structure and composition analysis have revealed that thermal annealing causes intermixing of the TiO 2 and PbS phases and influences the morphologies and optical properties of the hetero…
We investigate the dynamics of a tagged particle embedded in a strongly interacting confined liquid enclosed between two opposing flat walls. Using the Zwanzig-Mori projection operator formalism we obtain an equation of motion for the incoherent scattering function suitably generalized to account for the lack of trans…
Right- and left-handed cholesteric liquid crystals (CLCs) with the same reflection band at the same temperature have been successfully fabricated by doping oversaturated chiral dopant S811 (left-handed) or R811 (right-handed) in the liquid crystal host BL006. The reflection band of both the right- and left-handed CLCs…
Abstract The reaction of 6‐formyl‐2‐(hydroxymethyl)‐4‐methylphenol (LH2) with NiII and LnIII salts afforded a series of heterometallic pentanuclear compounds [Ni4Ln(L)4(OAc)2(MeOH)4](NO3)(MeOH) [LnIII = Gd (1), Dy (2), Tb (3), Ho (4)]. Four dianionic L2– ligands and two acetate anions hold together four NiII and one L…
Abstract A new redox‐amphoteric ligand comprising a p‐phenylene‐extended tetrathiafulvalene (TTF) core and two o‐quinone termini has been synthesized. This work was performed in an attempt to synthesize a bridging ligand by combining one of the most powerful organic donors with strong acceptor units in a single molecu…
The recently developed supramolecular hydrogelator system based on poly(ethylene glycols) end-functionalized with ureido-pyrimidinone (UPy) units has been shown to be eminently suitable as a drug delivery vehicle in soft tissues such as the heart and kidney. To understand the assembly behavior of this system in more d…
The valley physics in the two-dimensional graphenelike system has been put forward recently, and one of the key issues is to produce valley currents. We propose in this work to realize the topological valley resonance effect in graphene by using the time-dependent lattice vibration of optical phonon modes, which can p…
Inspired by nature, a number of techniques have been developed to fabricate the bionic structures of lotus leaves and moth eyes in order to realize the extraordinary functions of self-cleaning and antireflection. Compared with the existing technologies, we present a straightforward method to fabricate well-defined mic…
Two-dimensional nanomaterials usually have abnormal physical properties due to surface effects and large edge states. In this communication, it is demonstrated that porous hexagonal disulfide nanosheets exhibit clear room temperature ferromagnetism, where the observed ferromagnetism can be tuned by changing the porosi…
The efficient hydrophobization mechanism of a hydrophilic cellulose film surface with alkylketene dimer (AKD) was studied in terms of formation of β-ketoester bonds at AKD/cellulose interfaces and their nanosized distribution analysis. AKD-treated cellulose and nanocellulose films were sequentially extracted with chlo…
Broadband dielectric and Fourier transform infrared spectroscopies were applied to study dynamics and kinetics upon polymerization of bisphenol A diglycidyl ether (DGEBA) and 2-ethylhexylamine under different thermodynamic conditions. We found out that polymerization constant rates as well as activation barriers deter…
Bismuth layer-structured Bi7−xGdxFe3Ti3O21 (0.00 ≤ x ≤ 1.50) ceramics were synthesized by Pechini's method, in which gadolinium doping was used with a goal to enhance the magnetic response of the material. With increase in the Gd content of x, an obvious structural transformation, changing gradually from the originall…
We investigate strain effects on the magnetic anisotropy energy (MAE) and the magnetic moment of Y2Fe14B on the basis of density functional theory. We find that the MAE is significantly enhanced upon compression of the lattice. By applying second-order perturbation theory, the coupling among orbitals that is the most…
Conventional materials are being replaced in the field of engineering by composite materials, due to their tailorable properties and high specific properties. These materials are extensively used in structural applications. Damping is one of the important properties of the materials used in structures, and needs to be…
Abstract Three new trinuclear heterometallic [(Cu II L) 2 Co II X 2 ] complexes [H 2 L = N , N′ ‐bis(salicylidene)‐1,3‐propanediamine and X = thiocyanate ( 1 ), benzoate ( 2 ), or azide ( 3 )] have been synthesized by reacting the metalloligand [CuL] with Co(ClO 4 ) 2 · 6H 2 O and the NH 4 + or Na + salt of the corres…
A semiorganic nonlinear optical single crystal was grown from aqueous solution by a slow evaporation method at room temperature. The characterisation of the crystal was made using single crystal and powder X-ray diffraction analysis and it was found to be the l-threonine cadmium chloride (LTCC) crystallised in an orth…
