- Self-Fueled Biomimetic Liquid Metal Mollusk
Jie Zhang, Youyou Yao, Lei Sheng and Jing Liu
Article first published online: 3 MAR 2015 | DOI: 10.1002/adma.201405438
A liquid metal motor that can “eat” aluminum food and then move spontaneously and swiftly in various solution configurations and structured channels for more than 1 h is discovered. Such biomimetic mollusk is highly shape self-adaptive by closely conforming to the geometrical space it voyages in. The first ever self-fueled pump is illustrated as one of its typical practical utilizations.

A novel integrated power unit realizes both energy harvesting and energy storage by a textile triboelectric nanogenerator (TENG)-cloth and a flexible lithium-ion battery (LIB) belt, respectively. The mechanical energy of daily human motion is converted into electricity by the TENG-cloth, sustaining the energy of the LIB belt to power wearable smart electronics.
- Harvesting All Electrogenerated Excitons through Metal Assisted Delayed Fluorescent Materials
Zhi-Qiang Zhu, Tyler Fleetham, Eric Turner and Jian Li
Article first published online: 3 MAR 2015 | DOI: 10.1002/adma.201401772
Highly efficient and stable palladium complexes which exhibit both phosphorescence and delayed fluorescence are developed. We demonstrate that the emission from the two processes can be separately tuned through rational ligand modification. External quantum efficiencies over 20% are achieved and stable devices demonstrate an operational lifetime to 90% initial luminance estimated at over 20 000 h at 100 cd m−2.
- Is the Charge Transport in Dye-Sensitized Solar Cells Really Understood?
Frank Marlow, Abigail Hullermann and Lisanne Messmer
Article first published online: 3 MAR 2015 | DOI: 10.1002/adma.201404883
Electrical transients following laser excitation of dye-sensitized solar cells, thus far described by a complex model in the literature, are not consistent with this model. In particular, there are always delays of the electrical signal after the laser pulse. Although the correct theory has not yet been found, the present article is a step toward an improved understanding.
- High-Performance All-Polymer Solar Cells Via Side-Chain Engineering of the Polymer Acceptor: The Importance of the Polymer Packing Structure and the Nanoscale Blend Morphology
Changyeon Lee, Hyunbum Kang, Wonho Lee, Taesu Kim, Ki-Hyun Kim, Han Young Woo, Cheng Wang and Bumjoon J. Kim
Article first published online: 3 MAR 2015 | DOI: 10.1002/adma.201405226
The effectiveness of side chain engineering is demonstrated, to produce highly efficient all-polymer solar cells (efficiency of 5.96%) using a series of naphthalene diimide-based polymer acceptors with controlled side chains. The dramatic changes in the polymer packing, blend morphology, and electron mobility of all-polymer solar cells elucidate clear trends in the photovoltaic performances.
