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.

De novo active sites for resurrected Precambrian enzymes
Nature Communications, 2017 The emergence of novel catalytic functions in ancient proteins likely played a role in the evolution of modern enzymes. Here, the authors use protein sequences from Precambrian beta-lactamases and demonstrate that a single hydrophobic-to-ionizable amino ...

Short transmembrane domains with high-volume exoplasmic halves determine retention of Type II membrane proteins in the Golgi complex [PDF]
, 2013 It is still unclear why some proteins that travel along the secretory pathway are retained in the Golgi complex whereas others make their way to the plasma membrane.

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.

Self‐Cooling Molecular Spin Qudits
Advanced Materials, EarlyView.A material made of [GdEr] molecular dimers can encode a qudit and perform as a magnetic refrigerant. Microwave resonant pulses coherently manipulate its 16 spin states, while direct demagnetization measurements cool the material and a device down to temperatures below 1 K.

Linear algebra and optimization based controller design for trajectory tracking of typical chemical process [PDF]
, 2014 This paper presents a new controller design to tracking trajectory of a typical chemical process. The plant model is represented by numerical methods and, from this approach, the control actions for an optimal operation of the system are obtained.
