Synthesis and structure of silver and copper salts and complexes with polyhedral boron hydride anions, including closo-decaborate [B₁₀H₁₀]²⁻, closo-dodecaborate [B₁₂H₁₂]²⁻, 1-carba-closo- decaborate [1-CB₉H₁₀]⁻, carba-closo-dodecaborate [CB₁₁H₁₂]⁻, a...

The crystal growth of high-temperature oxide superconductors has been hampered by the complexities of these materials and the lack of knowledge of corresponding phase diagrams. The most common crystal growth technique adopted for these materials is t...

The adsorption of H₂O, NH₃ and HCOOH as polar molecules and C₆H₆ and CH₄ as non-polar ones on a series of zig-zag (6,0) single-walled boron nitride nanotubes (BNNTs) both being defect-free (P_BNNT) and containing defects at the nanotube walls has bee...

Polystyrene (PS) colloidal photonic crystals (CPhCs) containing silver nanoparticles (AgNPs) present tunable structural colors. PS CPhC color films containing a high concentration of AgNPs were prepared using self-assembly process through gravitation...

The relationship between chemical structure and spin state in a transition metal complex has an important bearing on mechanistic bioinorganic chemistry, catalysis by base metals, and the design of spin crossover materials. The latter provide an ideal...

Two new hydrazone compounds, 4-formylimidazole-4-hydroxybenzhydrazone dihydrate (1) and 2-nitrobenzaldehyde-2-furan formylhydrazone (2), were synthesized via the classical synthesis method. Their structure was determined via elemental analysis and X-...

The determination of crystal structures provides important information on the geometry of species constituting crystals and on the symmetry relations between them. Additionally, the analysis of crystal structures is so conclusive that it allows us to...

Hexagonal boron nitride (h-BN) is a well-known material whose use is almost restricted to lubricating applications in domains ranging from metallurgy to cosmetics. Howover, h-BN displays many other interesting properties, opening new perspectives for...

The assembly of colloidal building-blocks is an efficient, inexpensive and flexible approach for the fabrication of a wide variety of photonic materials with designed shapes and large areas. In this review, the various assembly routes to the fabricat...

This review is devoted to one of the most promising two-dimensional (2D) materials, graphene. Graphene can be prepared by different methods and the one discussed here is fabricated by the thermal decomposition of SiC. The aim of the paper is to overv...

The conformational preferences of benznidazole were examined through the application of DFT, PCM and QTAIM calculations, whose results were compared with crystallography data. The geometries were fully optimized with minimum potential energy surface...

The acoustic properties of a three-dimensional sonic crystal made of square-rod rigid scatterers incorporating a periodic arrangement of quarter wavelength resonators are theoretically and experimentally reported in this work. The periodicity of the...

Bragg band gaps of phononic crystals generally, but not always, open at Brillouin zone boundaries. The commonly accepted explanation stems from the empty lattice model: assuming a small material contrast between the constituents of the unit cell, avo...

This review summarizes the synthesis and coordination chemistry of a series of carboranyl ligands containing N,O donors. Such carborane-based ligands are scarcely reported in the literature when compared to other heteroatom-containing donors. The syn...

To investigate the π-extension effect on an unusual negative-charged spin crossover (SCO) Fe^III complex with a weak N₂O₄ first coordination sphere, we designed and synthesized a series of anionic Fe^III complexes from a π-extended naphthalene derivati...

Despite the extensive range of investigations on boronic acids (R-B(OH)₂), some aspects of their reactivity still need to be explored. This is the case for the coordination chemistry of boronate anions (R-B(OH)₃⁻), which has only recently been starte...
