Summary: A novel class of stable monoareno-pentalenes with an olefinic proton on each five-membered ring is introduced. The synthesis was achieved through a regioselective carbopalladation cascade reaction between ortho-arylacetyleno gem-dibromoolefins and TIPS-acetylene. These molecules could serve as experimental probes for magnetic (anti)aromaticity effects.

Summary: Genomic investigation reveals an American origin and two waves of invasion for the plant pathogen Xylella fastidiosa in France. Since its discovery in Italian olive groves in 2013, a wide diversity of Xylella fastidiosa strains from different subspecies of American origin have been reported in Europe. Strains from the multiplex subspecies (ST6 and ST7) were first identified in France in 2015, and the molecular evolution rate of this subspecies was estimated. A new VNTR-13 scheme was developed to trace the spread of the bacterium in France and suggests an initial introduction and spread in Provence-Alpes-Cote d'Azur (PACA), followed by two waves of introduction in Corsica from the PACA bridgehead populations.

Summary: We completed the crystal structure studies of two series of 1:1 complexes of lanthanoid and yttrium trinitrates with N,N, N',N'-tetrabutylamide of 1,10-phenanthroline-2,9-dicarboxylic acid (L1) and N,N,N',N'-tetrabutylamide of 4,7dichloro-1,10-phenanthroline-2,9-dicarboxylic acid (L2). The coordination of ligands L1 and L2 with central ions involves two phenanthroline nitrogen atoms and two amide oxygen atoms. The structural changes observed in the complexes agree with DFT calculations.

Summary: Insects have undergone repeated evolutionary transitions between synchronous and asynchronous flight modes. This study reveals that asynchrony likely evolved only once at the order level, with many reversions to the ancestral, synchronous mode. The findings suggest that these two flight modes are two regimes of the same dynamics and insects can transition between them with changes in physiological parameters. Additionally, the study integrates these two modes into an insect-scale robot, unlocking a new self-excited wingstroke strategy for engineered flight.

Summary: In this study, a three-dimensional crack twisted-bridging model is developed to investigate the fracture toughness of Bouligand structures, revealing that nanofibers bridge the crack surfaces in a twisting arrangement within the fracture process zone at the crack tip. Bouligand structures exhibit high and direction-independent fracture toughness, and their crack resistance increases with the pitch angle of nanofibers.

Summary: This study utilizes in situ transmission electron microscopy to investigate the unusual microscopic processes in a Sb2Te3/TiTe2 PCH architecture. The findings reveal that the template-modulated phase transition in this structure is two-dimensional (2D) in nature, with significantly different structural transformation paths and dynamics compared to bulk Sb2Te3. These changes result in suppressed amorphous relaxation and reduced crystallization stochasticity, which are highly advantageous for rapid and precise device operations.

Summary: Based on Huang's bridging model, this paper presents an analytical prediction scheme for the effective elastic properties of fuzzy fiber reinforced composites. The study investigates the effects of two-scale interphases on composite properties, evaluates the size and waviness effects of nanofillers, and validates the scheme's accuracy with experimental data. The introduction of slender nanofillers significantly enhances the composite's transverse and shear performance, depending on various parameters such as reinforcement contents and interphase stiffness.

Summary: This work systematically studies the structural, electronic, and optical properties of a 2D ferroelectric Ga2O3 bilayer system. It reveals the high tunability of the bilayer system under interlayer perturbation and biaxial strain, as well as a phase transition from vdW to ionic interlayer interaction induced by in-plane biaxial tensile strain. These insights hold significant prospects for experimental synthesis, characterization, and application of 2D Ga2O3 atomically thin layered systems.

Summary: In this article, a novel catalytic reaction using Pd(0) and Bronsted acid is reported for the synthesis of biologically important imidazolidinone-fused N-heterocycles through redox-neutral intramolecular N-allylation of indoles and pyrroles with alkynes. This atom-economical method is applicable to a wide range of substrates and eliminates the need for leaving groups or oxidizing agents commonly used in traditional allylation reactions.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
