- Strong Photocurrent Enhancements in Highly Efficient Flexible Organic Solar Cells by Adopting a Microcavity Configuration

Organic solar cells often suffer inefficient light harvesting due to short absorption path length limited by the low charge mobility of organic semiconductors. We demonstrate a flexible organic solar cell in a microcavity configuration using a TeO2/Ag semitransparent electrode to confine the optical field within the device with significant performance improvements and reaching a power conversion efficiency of 8.56%.

A “sticker-like” PLGA nanosheet with microgrooved patterns is developed through a facile combination of spin coating and micropatterning techniques. The resulting microgrooved PLGA nanosheets can be physically adhered on flat or porous surfaces with excellent stability in aqueous environments and can harness the spatial arrangements of cells, which make it a promising candidate for generating biomimic periosteum for bone regenerative applications.

Chunyan Liu, Yi Hou and Mingyuan Gao
Article first published online: 11 MAR 2014 | DOI: 10.1002/adma.201305535
Owing to the unique magnetic and optical properties associated with f-electrons, the rare earth (RE) nanoparticles have shown great potential for versatile in vivo applications, especially sensitive tumor imaging according to animal experiments. This Research News summarizes recent achievements in synthesis, surface modification, in vivo application, and toxicity of RE nanoparticles, and discusses their perspectives for clinical applications.

A simple and effective strategy involving nebulized ethanol assisted infiltration for the general synthesis of 3D structure-based vertically aligned carbon nanotube arrays (VACNTs) uniformly and deeply decorated with various transition-metal oxide (MOs) has been developed. Furthermore, it is demonstrated that the 3D structure-based VACNTs with decorated MnO2 can exhibit superior electrocatalytic oxygen reduction reaction activity, long-term stability, and an excellent resistance to crossover effects compared to the commercial Pt/C catalyst.
- Microfluidic-Based Generation of Size-Controlled, Biofunctionalized Synthetic Polymer Microgels for Cell Encapsulation
Devon M. Headen, Guillaume Aubry, Hang Lu and Andrés J. García
Article first published online: 11 MAR 2014 | DOI: 10.1002/adma.201304880
Cell and islet microencapsulation in synthetic hydrogels provides an immunoprotective and cell-supportive microenvironment. A microfluidic strategy for the genaration of biofunctionalized, synthetic microgel particles with precise control over particle size and molecular permeability for cell and protein delivery is presented. These engineered capsules support high cell viability and function of encapsulated human stem cells and islets.
