Enhanced Acoustic Adhesion Enabling Agile and Small Wall‐Climbing Robot Design With Anisotropic Origami Structure

open access: yesAdvanced Science, EarlyView.
This 28 g robot incorporates innovative ring structures and anisotropic origami springs to achieve high speeds and exceptional load capacity. It successfully carries a 100 g payload while ascending walls or ceilings at speeds of up to 8 and 20 cm/s, demonstrating enhanced adhesion and maneuverability over current climbing robots.

Low Threshold Vertical Cavity Surface Emitting Lasers Based on CsPbI3 Thin Films

open access: yesAdvanced Science, EarlyView.
The first vertical‐cavity surface‐emitting laser (VCSEL) based on CsPbI3 thin films is fabricated by planar hot pressing. By optimizing the cavity design through optical gain assessment and rigorous coupled‐wave analysis, the VCSEL achieved an exceptionally low lasing threshold of 2.8 µJ cm−2.

Habitat‐Specific Design Strategies for Untethered Soft Robots

open access: yesAdvanced Science, EarlyView.
Habitat shapes the design of untethered soft robots. Across land, water, air, and living tissues, environmental constraints govern viable combinations of compliant structures, actuation mechanisms, and energy delivery. This review connects these constraints with robotic performance and identifies design principles for advancing adaptable, durable, and ...

HADHA K406 Lactylation Regulates Metabolic Reprogramming and Suppresses Immune Responses in Gastric Cancer

open access: yesAdvanced Science, EarlyView.
HADHA K406 lactylation fuels fatty acid β‐oxidation and HMGCR‐dependent cholesterol biosynthesis, fostering immunosuppressive MDSCs and exhausted CD8+ T cells in gastric cancer. Loss of this modification blocks cholesterol production, remodels the tumor microenvironment, and tumor growth is suppressed via combined inhibition of HMGCR and LDHA ...

Coordinated control of acceleration slip regulation and active front steering for in-wheel motor driven electric vehicle based on dynamic slip ratio constraint.

open access: yesPLoS ONE
In-wheel motor driven electric vehicles are prone to issues such as wheel spin, vehicle sideslip, fishtailing, and steering instability when traveling on compacted snow surfaces. While traditional optimal slip ratio tracking aims to maximize longitudinal

To Be or Not to Be Eutectic: Anomalous Glass Forming Ability Governed by Melt Structural Complexity

open access: yesAdvanced Science, EarlyView.
Challenging the eutectic rule, congruently melting Ti–Cu alloys show greater glass‐forming ability than their eutectic counterparts. This arises from the congruent melt's structural complexity: higher cluster diversity and stronger inter‐cluster correlations from entropy–enthalpy competition.

Planetary Roller Hub-type Continuously Variable Transmission

open access: yesJixie chuandong
The wheel motor drive has the problem of insufficient power at low speeds when climbing hills. In this study, a new planetary roller wheel continuously variable transmission (CVT) is developed, which achieves independent variable speed drive of the wheel
