Rapid development in the area of cellulose biomass conversion to furanic platform chemicals has led to expectations of their valuable practical use. Impressive research progress in this direction has resulted in several achievements but at the same time identified a key challenge—the necessity to produce aromatic compounds. In this perspective, we analyze the current stage of development of the furanics-to-benzene conversion process (F2B process) in connection with a bioderived route to aromatic compounds. Cycloaddition reactions between bioderived C6-furans as diene components and alkene/alkyne units are discussed in detail, followed by considering the subsequent aromatization reaction. Progress in the development of the F2B process and future challenges are outlined in this perspective. The key role of the F2B process in the overall biomass to aromatics transformation is discussed in view of the implementation of carbon neutral sustainable technologies in practice.

Colloidal semiconductor nanocrystals have emerged as promising materials for next-generation light-emitting diodes (LEDs) owing to their solution processability, tunable emission wavelengths, narrow emission linewidths, and high photoluminescence quantum yields. Among them, anisotropic nanocrystals, including one-dimensional nanorods (NRs) and two-dimensional nanoplatelets (NPLs), offer additional opportunities for controlling transition dipole moment orientation and light out-coupling efficiency. These ...

The use of hydrophobic deep eutectic solvents (DESs) as extractants for metal ion separation is largely due to the ease of their preparation and the possibility of modifying them depending on the composition of the metal mixture to be separated. However, the most common approach to DES modification involves the replacement of the extractant, while ...

Two voluminous polymer silver(I) salts of perchlorinated dodecoborate clusters, {[(Me2CO)Ag(μ-Me2CO)2Ag(Me2CO)][μ-B12Cl12]}n (1) and {[DMFAg(μ-DMF)2AgDMF][μ-B12Cl12]}n (2) were synthesized. The 35Cl nuclear quadrupole resonance (NQR) spectroscopy supplemented with the X-ray diffraction data was applied for identifying and analyzing noncovalent interactions Cl···X in these salts. Whereas in X-ray diffraction, noncovalent interactions are associated with the presence of the shortened ...

Despite the well-established importance of chalcogen bonding in crystal engineering and supramolecular chemistry, experimental charge density data for TeII-centered chalcogen bonds have remained entirely absent, leaving the electronic nature of these interactions uncharacterized at the level of directly measured electron density. Here, we report the first high-resolution X-ray diffraction (HRXRD) study of TeII-centered chalcogen bonds, ...

Off-stoichiometric boron-doped chemically complex intermetallic alloys (CCIMAs) have recently emerged as a new avenue for overcoming the low temperature brittleness of ordered superlattices. However, their behavior at high temperatures remains unexplored. In this study, a novel (Ni39.6Co29.3Cr10Al15.8Ta3.3Nb2)98.5B1.5 CCIMA was prepared and its oxidation resistance over a wide temperature range (500 °C–950 °C) was studied. The ...

We report a high-performance implementation of the resolution-of-the-identity Hartree–Fock method that fully exploits the permutational symmetry of three-center electron repulsion integrals (ERI). The present implementation adopts a hybrid MPI+OpenMP parallelization strategy. Two different algorithmic approaches (with and without the pre-transformation of ERIs) are compared. A custom data layout introduced previously is employed. Designed to efficiently ...

Rangeland degradation is a global environmental challenge; however, intense debate persists between equilibrium (focused on the negative effects of grazing intensity) and non-equilibrium (emphasizing livestock mobility for adapting to climate variability) theories in rangeland ecology. In recent years, an integrative theory advocating the “coexistence of equilibrium and non-equilibrium” has emerged to reconcile this debate. However, ...

Targeted protein degradation represents a promising therapeutic strategy, yet its broader application is often limited by the scarcity of usable E3 ligases. Glutathione peroxidase 4 (GPX4) is a key target for inducing ferroptosis, but achieving sustained and potent inhibition remains challenging with conventional enzymatic inhibitors. Herein, we report the first small‐molecule GPX4 degraders that incorporate ...

We develop a three-mode statistical-mechanical theory for a two-conformer
solute in a near-critical solvent. A compressible lattice model with
vacancies yields the Gaussian free-energy functional for a critical conserved
density, an orthogonal noncritical conserved mode, and the local conformer
fraction. Their couplings follow from packing and cohesive interactions,
rather than being introduced phenomenologically. Kawasaki transport of the
two conserved fields and ...

Exact theories of electrolyte structure must satisfy the nonlocal constraints imposed by electrostatic screening, yet these constraints are most commonly formulated only for homogeneous bulk systems and at the level of two-point correlations. Here, we develop a unified field-theoretic framework that extends them to general inhomogeneous ionic fluids and nonlinear charge correlations. Using a standard ...

A heptafluorobutyric acid-induced cross-dehydrogenative coupling reaction of arylamines with 1,2,4-triazines has been described. This metal-free protocol enables regioselective para-C–H hetarylation of diverse arylamines including well-known fluorophore scaffolds, such as triphenylamine, carbazole, and phenothiazine, with easily accessible 1,2,4-triazines under mild conditions. This approach has potential for drug development and material design. ...

Single-crystal X-ray diffraction analyses unveil that complexes 1 and 3 are mononuclear, while complex 2 is dinuclear. All complexes further assemble into one-dimensional supramolecular chains mediated by N–H···N hydrogen bonds, which are reinforced by π···π stacking and Br···Br halogen interactions.
