چکیده
Li-Ion Battery Cathodes In article 2212098, Jaekwang Lee, Sung-Yoon Chung, and co-workers demonstrate that a significant amount of oxygen loss can be induced exclusively by lattice strain even in pristine layered oxides, LiCoO2 Li2MnO3, without any electrochemical Li extraction. Calculations based on density functional theory also clarify shear strain, among many different modes mechanical provide major contribution to the energetically favorable formation vacancies, critically supporting experimental observations.

Metamaterials: Snapping Mechanical Metamaterials under Tension (Adv. Mater. 39/2015).
By exploiting snap-through instabilities, D. Pasini and co-workers design a damage-tolerant mechanical metamaterial that snaps sequentially under tension, thereby accommodating a very large deformation up to 150%. On page 5931, they describe how the nonlinear mechanical response of the metamaterial can be robustly programmed by tuning the architecture of its unit cell.

Probing Electrochemical Cycling Stability of Li-ion Cathode Materials at Atomic-scale
Li-excess layered oxide high energy density materials are currently being considered as promising candidates for energy storage technologies in plug-in hybrid electric vehicles (PHEVs) or electric vehicles (EVs), owning to their high capacity (>250mAh/g), high energy density, and excellent safety.[1-3] Two major fundamental questions, however, must be resolved before their commercial implementa...
متن کاملThe Direct Electrochemical Investigation of Redox Enzymes
Even though the use of enzymes as useful analytical reagents when immobilized onto a transducer such as an electrochemical device has been reported in the literature for nearly two decades, the direct, i.e. unmediated electrochemistry of enzymes is, nevertheless, a rather recent development. Efforts will be made to introduce the fundamental basis for protein-surface interactions with emphas...
