Camera calibration under optimal conditions

Optics Express, 2011
Different methods based on photogrammetry or self-calibration exist to calibrate intrinsic and extrinsic camera parameters and also for data pre- and post-processing. From a practical viewpoint, it is quite difficult to decide which calibration method gives accurate results and even whether any data processing is necessary. This paper proposes a set of

MPI‐Guided Photothermal Therapy of Prostate Cancer Using Stem Cell Delivery of Magnetotheranostic Nanoflowers

Advanced Functional Materials, EarlyView.
Tumor‐tropic human mesenchymal stem cells (hMSCs) were used as delivery vehicles for magnetotheranostic gold–iron oxide nanoflowers. Magnetic particle imaging of the iron component demonstrated widespread intratumoral distribution and sustained retention in contrast to injection of naked nanoflowers.

The Effect of Purcell Cavities on the Lifetime of Thermally Activated Delayed Fluorescent Emitters

Advanced Functional Materials, EarlyView.
A pressing challenge to OLED displays and lighting is to balance high efficiency and long operational lifetime in the deep blue spectrum. The Purcell effect can reduce the triplet density and hence the probability for destructive energy‐driven triplet annihilation events that limit the OLED lifetime. Here we study of the Purcell effect on two different

Polyferrocene‐Based Cubosomes: Conversion to Magnetic Mesoporous Microparticles, Supramolecular Modification, and Oxidation Response

Advanced Functional Materials, EarlyView.
Polyferrocene block copolymers are synthesized and assembled into micron‐sized polymer cubosomes with double diamond lattice and pore diameter of ≈30 nm. The ferrocene functionality is retained within the polymer cubosome wall as demonstrated on supramolecular modification, and oxidative disassembly.

Contact Lens with Moiré Patterns for High‐Precision Eye Tracking

Advanced Functional Materials, EarlyView.
This work presents a passive contact lens for high‐precision eye tracking, integrating a microscopic moiré grating label. The parallax‐induced shift of macroscopic moiré patterns enables angle measurement with 0.28° precision using a standard camera under ambient light.
