Bistatic TerraSAR-X/F-SAR Spaceborne-Airborne SAR Experiment: Description, Data Processing and Results [PDF]

, 2010
We report about the first X-band spaceborne-airborne bistatic SAR experiment, using the German satellite TerraSAR-X as transmitter and DLR's new airborne radar system F-SAR as receiver. The data were acquired early November 2007.

Delivery of DNA‐encoded vaccines and proteins in mice using cutaneous suction‐mediated transfection

FEBS Open Bio, EarlyView.
Cutaneous suction‐mediated transfection in mice for delivery of DNA‐encoded vaccines and proteins. A critical limitation of DNA vaccines and other therapeutics is transfection in vivo to produce the encoded antigens or therapeutic proteins. Cutaneous suction‐based methods have demonstrated effectiveness in many animal models and have been successfully ...

First 3-D reconstructions of target hidden beneath foliage by means of polarimetric SAR tomography [PDF]

, 2012
SAR tomography (SARTom) is an imaging technique that allows multiple phase center separation in the vertical direction, leading to a 3-dimensional (3D) reconstruction of the imaged scene. Retrieval of volume structure information (e.g.

Low‐Flicker‐Noise MoS2 Transistors Enabled by High‐κ Rare‐Earth Oxychlorides for Mixed‐Signal Electronics

Advanced Functional Materials, EarlyView.
Single‐crystalline LaOCl and GdOCl form atomically abrupt, Cl‐terminated interfaces with MoS2, enabling near‐ideal switching and suppressed flicker noise. Carrier‐number‐fluctuation analysis yields effective noise‐derived interface trap densities of 1.15–1.94 × 1010 cm−2 eV−1, approaching hexagonal boron nitride levels with high‐κ coupling.

Integrated Multiband Smart Windows From UV to LWIR Based on Molecularly Engineered Thermochromic Hydrogels

Advanced Functional Materials, EarlyView.
A multiband smart window integrating a thermochromic poly (EEEA‐co‐NIPAM) hydrogel with functional layers, enabling dynamic VIS‐NIR solar modulation alongside UV shielding and low LWIR emissivity. The polymer network forms hydrogen‐bonding interactions, promoting chain collapse above a reduced lower critical solution temperature, and accelerating the ...
