Information about next year's meeting is available at the conference website. Just Published: Special Topic Section on Applied BiophysicsMedical biophysics and bioengineering/biotechnologies are rapidly expanding fields. JAP has witnessed a substantial increase in the submission of manuscripts in applied biophysics as a result. To encourage further expansion of this important area, JAP has published a Special Topic section on Applied Biophysics. A relatively small number of invited papers and review articles are grouped together in this Special Topic section. The aim was to seek out contributions in a number of important subfields of rapid growth and impact. Solicitation of papers representing key international research was based on peer recommendations and the guest editors’ knowledge of the subfields. The 48 published papers fall into one or more of seven areas, categorized according to the physical principle, methodologies, and techniques used to carry out the research:

A group of scientists at the Chinese Academy of Sciences has reported development of a new type of light emitting diode (LED) made from inexpensive, plasticlike organic materials. Designed with a simplified "tandem" structure, it can produce twice as much light as a normal LED -- including the white light desired for home and office lighting.

Scanning electron microscopy, atomic force microscopy, and optical spectroscopy are used to illustrate how ultrathin Al interlayers influence the morphology of Ag layers evaporated on top of organic materials and how closed layers with good conductivity can be achieved. Multilayer metal contacts are used to fabricate top-illuminated small-molecule organic solar cells (SM-OSCs) that reach efficiencies comparable to conventional SM-OSCs that employ tin-doped indium oxide as electrode. It is shown that combinations of Al and Au lead to similar results, suggesting a similar mechanism for the influence on morphological development of both Ag and Au.
High-flux coherent x-rays are necessary for the improvement of the spatial resolution in coherent x-ray diffraction microscopy (CXDM). High-resolution CXDM using Kirkpatrick–Baez (KB) mirrors is proposed, and the mirrors are designed for experiments using the transmission scheme at SPring-8.
Third-generation infrared (IR) systems provide enhanced capabilities such as larger numbers of pixels, higher frame rates, better thermal resolution, multicolor functionality, and/or other on-chip signal-processing functions. Fundamental and technological issues associated with the development and exploitation of third-generation IR photon detectors are discussed along with detector technology challenges including complicated device structures, thicker and multilayer material growth, and more difficult device fabrication, especially for large array sizes and/or small pixel dimensions.
The solid-phase epitaxial growth (SPEG) process of Si amorphized via ion implantation has been a topic of fundamental and technological importance for several decades. This work reviews the progress made in understanding stressed multidirectional SPEG processes. Attempts are made to correlate prior observations in single-directional stressed SPEG with observations from patterned stressed SPEG. However, it ultimately appears that much of the understanding of single-directional stressed-SPEG process cannot be reasonably extended to the multidirectional stressed-SPEG process.
We are pleased to announce the implementation of a new multimedia capability for the authors and readers of Journal of Applied Physics. Multimedia files for video clips or animated movies can be included in the online version of the paper. These multimedia files can be viewed by simply clicking on a link in the paper, provided the reader has a video player, such as Windows Media Player™, QuickTime Player™, or RealOne Player™ installed.
