Advanced Science, EarlyView.Electric‐field‐controlled antiferroelectric switching offers a ferroic pathway for reversible interconversion between symmetry‐distinct antiferromagnetic states in a two‐dimensional halide perovskite. A spin‐split altermagnet transforms into a spin‐degenerate type‐IV antiferromagnet through field‐driven structural symmetry reconstruction, enabling ...

smear layer formation in root canal
During instrumentation using hand instruments or rotary instruments in endodontics, the dentine will be incised and fragmented, forming a large amount of debris. This dentinal debris, alongside pulp remnants, bacteria and bacterial by-products, will form

Bidirectional Soft Catalysts for Improved Power Performance of Li‐S Batteries
Advanced Science, EarlyView.A soft polymer‐metal catalyst is integrated into the binder to create a catalytically active microenvironment that accelerates bidirectional sulfur redox kinetics in lithium‐sulfur batteries. A model polyvinyl alcohol‐Cu catalyst enables high areal capacities at demanding current densities and stable cycling in pouch‐cell prototypes at 0.5 C, achieving

Magnetic Water Cleaning of Estrogens via Tight yet Dynamic Binding to Nanoparticles
Advanced Science, EarlyView.Micropollution is one of the big challenges humanity faces with estrogen hormones being emerging pollutants of concern. Here, a supramolecular design strategy is presented that generates a simple nano‐adsorbent material to magnetically remove low‐concentrated estrogens from water.

Advanced Science, EarlyView.The Tuta absoluta salivary effector TaCRVP subverts tomato immunity by hijacking host catalase SlCAT2. Through a sophisticated dual mechanism, TaCRVP simultaneously promotes SlCAT2 tetramerization for activation and blocks its SlAdBiL‐mediated degradation for stabilization.

Advanced Science, EarlyView.TUBA1B is consistently upregulated in hepatocellular carcinoma and sustains malignant progression by stabilizing G3BP2. By restraining TRIM25‐associated K48‐linked ubiquitination, TUBA1B preserves the G3BP2–IκBα complex and basal NF‐κB/p65 activity. Concurrent TUBA1B/G3BP2 upregulation identifies an aggressive HCC subgroup with enhanced p65 activation ...

Chelation‐Driven Dual‐Interface Regulation for Long‐Life Aqueous Zn–I2 Batteries
Advanced Science, EarlyView.Zn2+–TPEN coordination generates TPEN‐derived coordination species (TCC) that contribute to the regulation of both electrode interfaces. At the Zn anode, it creates an interfacial environment with reduced water accessibility that suppresses HER and corrosion while promoting uniform deposition; at the I2 cathode, it captures polyiodide to inhibit ...
