Bio‐Inspired Gradient Heterogeneous Architectures for Ultrasensitive and Robust Strain Sensors via Programmable Crack Engineering

open access: yesAdvanced Science, EarlyView.
Inspired by the insect campaniform sensillum, a heterogeneous bilayer strain sensor is developed based on a unique impedance mismatch and three‐dimensional structural dynamic percolation strategy. The sensor enables real‐time multi‐joint teleoperation of three joints and the gripper using a six‐degree‐of‐freedom robotic‐arm platform.

INVESTIGATION OF STALL FLUTTER OF FAN BLADES BY BLADE TIP-TIMING SYSTEM

open access: yes
Flutter is a system mode that all blades vibrate at thesame frequency but with a different phase angle, which canform a nodal diameter (ND) pattern. One of the advantagesof blade tip-timing (BTT) technique is to measure thevibrational displacements of all blades, which makes BTTa potential method to study flutter.

One‐Step Induction of Oogonia‐Like and Pro‐Spermatogonia‐Like Cells From Porcine Pluripotent Stem Cells

open access: yesAdvanced Science, EarlyView.
This study established a one‐step method inducing pro‐spermatogonia‐like (activating SOX17) and oogonia‐like (activating SOX17/TFAP2C) cells from porcine pgEpiSCs with a NANOS3‐tdTomato reporter. EGF activates the core PGC program and supports survival; BMP4 further induces NANOS3 and DDX4 expression; IWR1 enhances PGCLC efficiency by suppressing ...

Solution‐Shearing of Highly Smooth Ion‐Gel Thin Films: Facilitating the Deposition of Organic Semiconductors for Ion‐Gated Organic Field Effect Transistors

open access: yesAdvanced Electronic Materials, Volume 11, Issue 6, May 2025.
A straightforward method is introduced to produce ion‐gel films with very low surface roughness by employing a solution‐shearing coating process. These ion‐gel films permit the growth of crystalline thin films of various small molecule organic semiconductor molecules directly on top of the ion‐gel layer, thereby enabling “inverted” small molecule ...

MoS2 Memristors Made by Liquid–Liquid Interface Assembly and Ultraprecise Metal Printing

open access: yesAdvanced Electronic Materials, EarlyView.
A cleanroom‐free, fully additive fabrication route combines ultraprecise printed silver electrodes with Langmuir–Schaefer‐deposited bilayer MoS2 to realize ultralow‐power resistive switching devices. The resulting microscale memories exhibit low operating voltages, a large memory window, stable retention and endurance, demonstrating a scalable and cost‐

Alcohol‐Adduct Mediated Precursor Stabilization Strategies for Conformal SnO2 Layers in Highly Efficient and Stable Perovskite Solar Modules

open access: yesAdvanced Energy Materials, EarlyView.
An alcohol‐adduct‐mediated strategy is employed to stabilize tin isopropoxide for the formation of a homogeneous double electron transport layer (ETL) incorporating SnO2 nanoparticles (NPs). This double‐ETL exhibits improved optical and charge‐transport properties due to reduced defect density and better energy level alignment, resulting in high ...
