Advanced Synthesis &Catalysis, EarlyView.A novel methodology for the construction of aromatic and heteroaromatic trifluoropropynyl derivatives has been developed. The new protocol is based on a tandem Sonogashira cross‐coupling reaction between a bench‐stable trifluoropropynyl carbinol reagent, generated from the commercially available and inexpensive hydrofluoroolefin‐1234yf gas, and (hetero)

Advanced Synthesis &Catalysis, EarlyView.Chiral potassium base catalysts featuring 1,1´‐bi‐2‐naphthol‐derived chiral crown ethers as ligands promote a tandem allylic isomerization/asymmetric aldol‐Tishchenko reaction of allylic alcohols and aldehydes. This method provides enantioenriched 1,3‐diols with excellent diastereoselectivity and high enantioselectivity, thereby expanding the synthetic

Aerobic Oxidative Dethioacetalization Catalyzed by an Iron Phthalocyanine Complex
Advanced Synthesis &Catalysis, EarlyView.A protocol for iron octacarboxyphthalocyanine‐catalyzed aerobic oxidative dethioacetalization in an aqueous solvent is developed. This method can efficiently convert a broad range of dithioacetals into the corresponding carbonyl compounds. Inspired by enzyme‐mediated redox processes, the environmentally friendly catalytic system exhibits remarkable ...

Domino Synthesis of Functionalized Cyclic Acetals From Organic Carbonates
Advanced Synthesis &Catalysis, EarlyView.Cyclic carbonates equipped with acrylic functional groups are shown to undergo a domino process in the presence of a suitable alkoxide to deliver novel types of decorated cyclic acetals. The developed protocol combines practical conditions and a wide scope and features a new reactivity modus for these carbon dioxide‐derived heterocyclic precursors.

Electronic Nose for Indoor Mold Detection and Identification
Advanced Sensor Research, EarlyView.This study explores the potential of a SnO2 nanowire‐based chemiresistive electronic nose not only to detect but also to identify two common indoor mold species, Stachybotrys chartarum and Chaetomium globosum on two different growth substrates. In a laboratory setup, the electronic nose displays high classification performance using optimized linear ...

Advanced Science, EarlyView.A field‐effect transistor incorporating type‐I InP/ZnSe core–shell quantum dots demonstrates light‐ and gate‐tunable synaptic plasticity. By leveraging field‐assisted photoinduced charge trapping, the device emulates essential neuromorphic functions, including paired‐pulse facilitation, memory consolidation, and classical conditioning.

Advanced Science, EarlyView.Current SARS‐CoV‐2 vaccines generate short‐lived, strain‐specific immunity. A polymeric TLR7 agonist nanoparticle (TLR7‐NP) adjuvant enhances lymph node targeting and promotes early and sustained germinal center responses toward conserved S2 epitopes of the spike protein.
