High‐Entropy Materials for Water Splitting: An Atomic Nanoengineering Approach to Sustainable Hydrogen Production

open access: yesAdvanced Materials, EarlyView.
High‐entropy materials (HEMs), typically composed of five or more principal elements in near‐equimolar ratios, offer significant potential due to their unique properties. This review outlines the emergence and structural evolution of HEMs, followed by an in‐depth discussion of the elemental roles (active sites, promoters, or stabilizers) for water ...

Gastric Adenocarcinoma with Yolk Sac Tumor Differentiation and Liver Metastasis of Yolk Sac Tumor Component

open access: yesCase Reports in Oncological Medicine, 2013
Gastric adenocarcinoma with yolk sac tumor (YST) differentiation has rarely been reported. We report a case of primary gastric adenocarcinoma with yolk sac tumor differentiation and liver metastases of the YST component in a 50-years-old patient.

Temporal transcriptome analysis of the chicken embryo yolk sac

open access: yesBMC Genomics, 2014
BackgroundThe yolk sac (YS) is an extra-embryonic tissue that surrounds the yolk and absorbs, digests and transports nutrients during incubation of the avian embryo as well as during early term mammalian embryonic development.

Hyperspectral Fluorescence Imaging with a New Polarity‐Ultrasensitive Fluorescent Probe

open access: yesAdvanced Science, EarlyView.
Based on the critical role of the π‐spacer in determining wavelength sensitivity to microenvironmental polarity, a new fluorescent probe, Lipi‐PS is rationally developed, which exhibits the highest polarity‐sensitivity so far. Its integration with hyperspectral fluorescence imaging enables multiscale polarity mapping across cells, tissues, and ...
