High‐Throughput Encapsulation of Stem Cells: Characterizing Dynamic Culture Variability With a Millifluidic Approach

Advanced Healthcare Materials, EarlyView.
A high throughput millifluidic encapsulation platform is engineered and standardized. The system's output allows the monitoring of cell expansion in strong dynamic conditions. High polymer crosslinking leads to higher cell proliferation and lower cell growth on microgel's surface.

Generalizing Gelatin Methacryloyl Granular Hydrogel Fabrication Using Stable Microgels with Predictable Stiffness

Advanced Healthcare Materials, EarlyView.
Gelatin methacryloyl (GelMA) granular hydrogel scaffolds (GHS) are fabricated using a generalized two‐step photocrosslinking approach to yield stable (non‐dissolving) microgels suitable for in situ covalent assembly under physiological conditions. A phase diagram is developed to define the interplay between individual microgel stability and scaffold ...

51 Pegasi - a planet-bearing Maunder minimum candidate

, 2009
We observed 51 Peg, the first detected planet-bearing star, in a 55 ks XMM-Newton pointing and in 5 ks pointings each with Chandra HRC-I and ACIS-S. The star has a very low count rate in the XMM observation, but is clearly visible in the Chandra images ...

Setting a value for a currency: Interest rate, bank reserve ratio or pegging to a basket of currencies of major trading partners

, 2017
What is the value of a currency on a daily basis? How do we value a currency? Is it a fixed price relative to gold, as in the gold standard? In the era of semi or fully flexible exchange rates, prices of currencies move on a minute basis in currency exchanges, but what are the fundamental underpinnings of a currency, and how do we modulate its value ...

Semiconducting Polymer Nanoparticles as Multimodal Agents for Optical and Magnetic Resonance Imaging

Advanced Healthcare Materials, EarlyView.
Semiconducting polymer nanoparticles (SPNs) exhibit many advantageous optical and biological properties. Multimodal SPN‐based contrast agents that integrate several imaging modalities yield a wealth of information through the use of different imaging mechanisms.
