An In Vitro Human Segmentation Clock Model Derived from Embryonic Stem Cells
Cell Reports, 2019 Summary: Defects in somitogenesis result in vertebral malformations at birth known as spondylocostal dysostosis (SCDO). Somites are formed with a species-specific periodicity controlled by the “segmentation clock,” which comprises a group of oscillatory ...

Exciton Dynamics in Layered Halide Perovskite Light‐Emitting Diodes
Advanced Materials, EarlyView.This review discusses the exciton dynamics in layered halide perovskitelight‐emitting diodes (PeLEDs). It opens with a summary of the structural and photophysical aspects, followed by an exploration of controlling dimensionality and cascade exciton transfer in quasi‐2D PeLEDs.

Spectral oscillations in backscattering of light from a biological cell [PDF]
arXiv, 2009 Possible origins of the experimentally observed beat-like signal in elastic light backscattering from an epithelial biological cell are identified. The source of the beat-like signal is most likely the cellular nucleus, which is a spheroidal particle with an optically sharp edge, low relative index of refraction, and a size parameter in the resonant ...

Advanced Materials, EarlyView.The rise of lead halide perovskite semiconductors has enabled high‐performance LEDs with internal quantum efficiencies approaching 100%. In order to further enhance the external quantum efficiencies limited by light outcoupling effects, in this account, the strategies for reducing energy dissipation through the substrate, waveguide, and evanescent ...

Both cellular ATP level and ATP hydrolysis free energy determine energetically the calcium oscillation in pancreatic $β$-cell [PDF]
arXiv, 2018 In pancreatic $\beta$-cells, calcium oscillation signal is the core part of glucose-stimulated insulin secretion. Intracellular calcium concentration oscillates in response to the intake of glucose, which triggers the exocytosis of insulin secretory granules. ATP plays a crucial part in this process.

Advanced Materials, EarlyView.2,2,6,6‐Tetramethylpiperidin‐1‐oxyl radical (TEMPO)‐oxidized cellulose nanofiber (TOCN) is presented as a class of expanded nanofibrous electrode binders for lean‐electrolyte lithium–sulfur (Li–S) batteries. Owing to the increased active sites for intermolecular interaction with Li polysulfides (LiPS), the TOCN binder promotes the declustering of LiPS,

Advanced Materials, EarlyView.An organic BTHG agent called OTBP with prominent crystallinity is developed. The resonant absorption at 433 nm and prominent crystallinity of OTBP enhance its BTHG efficiency when excited by a 1300 nm femtosecond laser. Tuning the size of OTBP nanocrystals based on Mie scattering theory successfully enables them to achieve high‐contrast muti‐organ ...
