Dissecting the Spatial and Single‐Cell Transcriptomic Architecture of Cancer Stem Cell Niche Driving Tumor Progression in Gastric Cancer

open access: yesAdvanced Science, EarlyView.
A single‐cell and spatial transcriptional atlas reveals the architecture of human gastric cancer stem cell (CSC) niche and the developmental trajectory of CSCs. These CSCs interact with immunosuppressive immune cells thereby constructing immune‐suppressive niche, and inflammatory cancer‐associated fibroblast (iCAFs) to enhance stemness through ...

Revealing the Origin and Nature of the Buried Metal‐Substrate Interface Layer in Ta/Sapphire Superconducting Films

open access: yesAdvanced Science, EarlyView.
The origin and nature of metal‐substrate interface layer in Ta/sapphire‐based superconducting films is investigated using synchrotron X‐ray reflectivity and scanning transmission electron microscopy. An intermixing layer, ≈0.65 nm thick containing Al, O, and Ta atoms, is identified at the interface.

Direct‐Ink‐Writing Printed Stretchable Eutectic Gallium–Indium Antenna for Robust Wireless Communication

open access: yesAdvanced Science, EarlyView.
In summary, a universal EGaIn‐based DIW printing strategy is presented for fabricating wideband stretchable antennas. The printed antenna achieves an operating bandwidth of 3.75–8.21 GHz (fractional bandwidth: 75%), a peak gain of 1.8 dB and a radiation efficiency of 76.6%, surpassing state‐of‐the‐art stretchable antennas. More importantly, the antenna

Surface Engineering Enabled Capacitive Gas‐Phase Water Molecule Sensors in Carbon Nanodots

open access: yesAdvanced Science, EarlyView.
A surface engineering strategy is developed to tune the molecular affinity of carbon nanodots (CDs), leading to capacitive sensors with an impressive detection range from 11% to 98% relative humidity (RH). These sensors demonstrate high sensitivity, with 3.3 × 105 pF/RH, and an exceptional response of 1.8 × 108 % at 98% RH.
