Advanced Materials, EarlyView.TiC Colloidal variants are synthesized via a green and waste‐free laser fragmentation technique. The surface and elemental composition of the TiC colloids are tuned through laser‐induced carbon nucleation and nitridation while maintaining their crystal integrity. These changes maximize light–colloid interactions, thereby improving photo thermalization.

Shapeshifting Nanocatalyst for CO2 Conversion
Advanced Materials, EarlyView.A multi‐modal in situ characterization of Ag‐Cu nanoparticles during CO2 photoreduction sheds light on dynamic transformations occurring during reaction. The Cu(core)‐Ag(shell) nanoparticles present the Ag replacement by Cu atoms. Ag is trapped at the subsurface forming a Ag‐Cu‐O phase, and the nanoparticle spreads over the substrate.

Detecting the Six Polytypes of Five‐Layer Graphite
Advanced Materials, EarlyView.The six possible periodic crystals—so‐called polytypes of Penta layer graphene are identified using Raman, second harmonic, and electric surface potential measurements. The measurements reveal the polytypes’ abundance, relative stability, and annihilation dynamics, crucial for future multiferroic SlideTronic applications.

Reconfigurable Magnetotransport in MnBi2Te4 via Gate and Magnetic Field Tuning
Advanced Materials, EarlyView.Gate‐tunable magnetoresistance sign reversal under in‐plane magnetic fields is observed in an ultrathin MnBi2Te4 device, arising from spin reorientation and distinct scattering mechanisms. Moreover, angular‐dependent measurements reveal clear gate‐controlled magnetotransport anisotropy, underscoring the strong coupling between gating, spin ...
