Direct growth of multigrain platinum nanowires on sulfur-doped graphene (PtNW/SG) is reported. The growth mechanism, including Pt nanoparticle nucleation on SG, followed by nanoparticle attachment with orientation along the <111> direction is highlighted. PtNW/SG demonstrates improved Pt mass and specific activity compared to commercial catalysts towards oxygen reduction, in addition to dramatically improved stability through accelerated durability testing.
- Peptide Assembly-Driven Metal–Organic Framework (MOF) Motors for Micro Electric Generators

Peptide–metal–organic framework (Pep-MOF) motors, whose motions are driven by anisotropic surface tension gradients created via peptide self-assembly around frameworks, can rotate microscopic rotors and magnets fast enough to generate an electric power of 0.1 μW. A new rigid Pep-MOF motor can be recycled by refilling the peptide fuel into the nanopores of the MOF.

The inorganic-based laser lift-off (ILLO) process as a methodology for flexible electronics is demonstrated by K. J. Lee and co-workers on page 7480. The 32 × 32 one selector–one resistor (1S-1R) crossbar-structured memory arrays for 1 kbit flexible memory are initially fabricated on a rigid substrate using conventional micro-fabrication, then transferred without mechanical damage via the ILLO process using the laser-material interaction.

On page 7427, J. Kim, H. Hiroi, T. K. Todorov, D. B. Mitzi, and co-workers report high-efficiency Cu2ZnSn(S,Se)4 solar cells by applying In2S3/CdS double emitters. This new structure offers a high doping concentration within the Cu2ZnSn(S,Se)4 solar cells, resulting in substantial enhancement in the open-circuit voltage. The 12.4% device is obtained with a record open-circuit voltage deficit of 593 mV.
