Metal (n+1)p‐nd Orbital Hybridization and Excited‐State Metal–Ligand π‐Interactions Enable d10 Carbene‐Metal‐Amide TADF OLEDs with High Efficiency and Long Operational Lifetime

open access: yesAdvanced Science, EarlyView.
We elucidate the key roles of metal p‐d orbital hybridization, excited‐state metal–ligand π‐interactions, and structural rotation in TADF of d10 CMA complexes. Introducing electron‐withdrawing or π‐extended ligand substituents weakens excited‐state metal‐ligand π‐interactions and improves kTADF, but may compromise emitter stability in device operation.

Xenogeneic Mitochondrial Transplantation Improves Selected Age‐Associated Phenotypes in Mice

open access: yesAdvanced Science, EarlyView.
Yak‐derived xenogeneic mitochondrial transplantation improves selected age‐associated phenotypes in mice, enhances mitochondrial functional readouts, and engages host mitochondrial quality‐control pathways. Broad tissue biodistribution, increased ATP production and mtDNA copy number, reduced ROS levels and dysfunctional mitochondria, improved motility ...

Aerodynamic roll damping of a T-tail transport configuration [PDF]

open access: yes, 1974
The aerodynamic roll damping and the yawing moment due to roll rate for a model of a T-tail transport with aft-mounted engines were measured by means of a small-amplitude forced-oscillation mechanism. The tests were made for Mach numbers between 0.21 and

Thermally Processable, Transparent, Mechanically Tunable and Robust Bioplastics From Wastepaper

open access: yesAdvanced Science, EarlyView.
Unlike conventional inefficient or low‐value wastepaper recycling, a directional transformation strategy is employed to convert whole wastepaper into intact bioplastics with tunable mechanical properties in our work. These bioplastics can be processed into flexible bags or rigid containers and exhibit high transparency, water resistance, repairability,

Vulnerability Assessment for Excessive Acceleration Failure Mode of an Indonesian Ro-Ro Ferry by Model Experiment

open access: yesInternational Journal of Technology
The Indonesian ro-ro ferries have a large breadth-to-draught ratio and metacentric height. The passenger and crew accommodations are located at a significantly higher position from the roll axis because the main deck is used as a vehicle deck.

From Defense Executor to Engineering Target: Harnessing Lignin for Crop Resistance

open access: yesAdvanced Science, EarlyView.
Lignin serves as both a physical and chemical executor of broad‐spectrum plant immunity. This review systematically summarizes classical and recent advances in lignin‐mediated immunity, outlines the multifaceted regulatory modules controlling lignification under biotic stress, discusses key physiological and biochemical mechanisms behind lignin‐based ...

Long-term prediction of nonlinear ship roll motion using RAO

open access: yesApplied Ocean Research
This study proposes two practical methods for estimating the long-term probability of the exceedance distribution of ship roll motion with nonlinear damping. One is based on our previously proposed RTP method, which is applicable to nonlinear roll motion

A Smart Fluid‐Hydraulic System Based on MRF Valve Control and Its Application in Flexible Grasping

open access: yesAdvanced Science, EarlyView.
This study introduces a smart fluid hydraulic system using MRF valve control for flexible gripping. An MRF‐MSV with an integrated excitation coil and micro‐textured damping channels is designed and validated; micro‐texturing increases hydraulic resistance. Coupled with a soft actuator, the MRF‐MSV enables dynamic bending and grasping.
