Spin and Charge Control of Topological End States in Chiral Graphene Nanoribbons on a 2D Ferromagnet
Advanced Materials, EarlyView.Chiral graphene nanoribbons on a ferromagnetic gadolinium‐gold surface alloy display tunable spin and charge states at their termini. Atomic work function variations and exchange fields enabe transitions between singlet, doublet, and triplet configurations.

Estimating Causal Impacts of Human Recreation on Wildlife in the Absence of Experimental Controls
Conservation LettersMuch recent research has focused on the impact of human recreation on wildlife, but relatively few studies have used causal inference approaches; doing so would strengthen recreation management and decision‐making.

Global Ecology and Conservation, 2015 The grizzly bear (Ursus arctos horribilis) population in the Greater Yellowstone Ecosystem (GYE) is perceived to have been isolated from the population in the Northern Continental Divide Ecosystem for a century.

Advanced Materials, EarlyView.Bioorthogonal chemistry was applied to intracellularly photoactivate Doxorubicin (Dox) using gold nanostars (AuNSt) and near‐infrared (NIR) light. Two prodrugs were used: one photoactivatable, masked with 2‐nitrobenzyl carbamate (proDox1) and another photolabile, masked with 2‐nitrobenzyl diol (proDox2), which was attached to the AuNSt surface.

Grizzly Bear and Black Bear Marking Behavior
, 2010 Marking activity is common among ursids but little information has been quantified about this behavior. We describe marking behavior of sympatric grizzly bear (Ursus arctos) and black bear (U.

Advanced Materials, EarlyView.The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.

Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes
Advanced Materials, EarlyView.Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.
