An Update on the Hubble Constant from Surface Brightness Fluctuations

The surface brightness fluctuation (SBF) method is a powerful way to measure distances to evolved galaxies without recent star formation. We have published a value of the Hubble constant using WFC3/IR to measure distances out to 100 Mpc, tied indirectly to a Cepheid calibration.

The Surface Brightness Fluctuation Distance to the Coma Cluster

, 2015
The Coma cluster, as one of the closest very rich clusters of galaxies, is commonly used as a reference point in the cosmic distance ladder. We measured the surface brightness fluctuation (SBF) distance to NGC 4874, the cD galaxy in the Coma cluster, using the F160W (H-band) filter in the WFC3/IR camera on the Hubble Space Telescope.

Regulating the Interphase Strain in High‐Entropy Oxide Thin Films – An Approach to Attaining Giant Energy Storage Capability under Moderate Electric Fields

Advanced Functional Materials, EarlyView.
This work demonstrates an interphase strain engineering strategy to regulate capacitive energy storage performance in high‐entropy oxide thin films. Through introducing pyrochlore nanocolumns, the polarization response of perovskite unit cells is strengthened, yielding recoverable energy densities up to 93 J cm−3 with an efficiency of 83% under ...

Versatile Green Transfer of Magnetoelectronics with Loss‐Free Performance and High Adhesion for Interactive Electronics

Advanced Functional Materials, EarlyView.
An environmentally friendly transfer printing method of nm‐thick giant magnetoresistive (GMR) sensors is demonstrated. This method, relying on water and biocompatible polyvinyl alcohol (PVA) polymer without the need of complex treatments, allows transferring thin films to a wide range of biological, organic, and inorganic substrates.

Evolving Platinum‐Copper Nanostructures for Enhanced Photothermal Therapy and Controlled Copper Release in Cancer Therapy

Advanced Functional Materials, EarlyView.
Platinum‐Copper bimetallic nanoparticles may evolve depending on their synthesis under tumor microenvironment conditions and play a dual role as chemotherapeutic agents after releasing Cu ions and as near infrared photothermal agents with the Pt‐rich remaining frames.
