Exploring Ligand Effects in the Selective Catalytic Dehydrogenative Borylation of Alkynes with Aluminum

Advanced Synthesis &Catalysis, Volume 368, Issue 1, January 2026.
Proper selection of a modified guanidinato ligand allows for the selective catalytic dehydroborylation of terminal alkynes by an air‐stable aluminum complex. A plausible reaction pathway is suggested based on DFT studies, where the auxiliary substituent of the guanidinato ligand actively participates in the activation of the σ CH bond.

Programmable Chiral Radiation via Spin‐Decoupled Metasurface with Integrated Compound Phases

Advanced Science, Volume 13, Issue 1, 5 January 2026.
A programmable spin‐decoupled metasurface integrating propagation and geometric phases enables high‐purity chiral radiation with reconfigurable emission direction. Spin‐selective radiators combined with a compound phase decoupling strategy suppress undesired components, while embedded PIN diodes allow real‐time directional control.

Paradoxical Topological Soliton Lattice in Anisotropic Frustrated Chiral Magnets

Advanced Science, Volume 13, Issue 5, 27 January 2026.
The article describes the discovery of a stable skyrmion‐antiskyrmion lattice (S‐AL) in anisotropic frustrated chiral magnets. This lattice has a net‐zero topological charge due to a balanced population of skyrmions and antiskyrmions. This is a paradoxical finding since these particles normally annihilate each other.

Mechanism of Anomalous Anisotropic Colossal Magnetoresistance in Quasi‐2D Mn3Si2Te6 Bulk Single Crystal

Advanced Science, Volume 13, Issue 2, 9 January 2026.
The external field exceeds Hd, the speed polarization abruptly reorients to align with the Mn magnetic moments, leading to an MR ≈ −100%. Abstract Mn3Si2Te6, quasi‐2D ferrimagnetic semiconductor, exhibits anomalous saturated colossal magnetoresistance (CMR) only when a magnetic field is applied along its magnetic hard magnetization axis, suggesting ...

Pressure Effects on Monolayer FeCl2: Above‐Room‐Temperature Ferromagnetism with In‐Plane Electric Polarization and Interface‐Free Magnetic Tunnel Junctions

Advanced Electronic Materials, Volume 12, Issue 2, 21 January 2026.
We investigate the influence of hydrostatic pressure on the physical properties of monolayer FeCl2${\rm FeCl}_2$ for spintronics applications. A phase transition from a ferromagnetic half‐metal to a ferromagnetic semiconductor is unveiled at 4.6 GPa, accompanied by a transition from a non‐polar (1T) to a polar (1H) structure.
