A Multifunctional Polar Amino Acid for Mixed Tin‐Lead Perovskites and All‐Perovskite Tandems

open access: yesAdvanced Science, EarlyView.
AsnCl improves film orientation and crystallinity, suppresses Sn4+ and PbI2 defects, and prolongs carrier lifetimes, enabling a 22.54% efficiency and enhanced stability in Sn–Pb perovskite solar cells. The AsnCl‐treated tandem device achieves a steady‐state PCE of 28.24%, underscoring the effectiveness of additive molecular engineering for high ...

Novel Antifungal Scaffold Targeting Tubulin Overcomes Sclerotinia Sclerotiorum Resistance

open access: yesAdvanced Science, EarlyView.
Addressing pesticide resistance, novel chromone‐acylhydrazone hybrids targeting fungal tubulin are synthesized. Compound G24 potently inhibited S. sclerotiorum (EC50 = 0.21µg mL−1) and demonstrated enhanced field performance via microencapsulation, offering a sustainable strategy against resistance and for global food security.

Engineered Multifunctional Hydrogel Delivering Novel CBX7 Inhibitor Modulates Cuproptosis Via Liquid–Liquid Phase Separation to Restore Cardiac Function in Aged Myocardial Infarction

open access: yesAdvanced Science, EarlyView.
An age‐adapted therapy pairs δ‐Amyrenone, a CBX7 inhibitor, with an alginate hydrogel (CSAδ) to rescue infarcted elderly hearts. CSAδ disrupts CBX7–ATP7A liquid–liquid phase separation, restores ATP7A trafficking and copper efflux, suppresses cuproptosis, supplies oxygen, scavenges ROS, promotes M2 polarization, supports angiogenesis, and enhances ...

Array Radar Three-Dimensional Forward-Looking Imaging Algorithm Based on Two-Dimensional Super-Resolution

open access: yesSensors
Radar imaging is a technology that uses radar systems to generate target images. It transmits radio waves, receives the signal reflected back by the target, and realizes imaging by analyzing the target’s position, shape, and motion information. The three-

Custom large scale integrated circuits for spaceborne SAR processors [PDF]

open access: yes
The application of modern LSI technology to the development of a time-domain azimuth correlator for SAR processing is discussed. General design requirements for azimuth correlators for missions such as SEASAT-A, Venus orbital imaging radar (VOIR), and ...

A Virtual Clinical Trial of Psychedelics to Treat Patients With Disorders of Consciousness

open access: yesAdvanced Science, EarlyView.
Disorders of consciousness after severe brain injury are marked by reduced complexity of brain activity and limited treatment options. Using personalized whole‐brain models, this study shows that simulated lysergic acid diethylamide (LSD) and psilocybin shift patient brain dynamics closer to criticality.

Structure‐Tailoring Cerium Nanozymes with Self‐Cascade ROS Scavenging Catalysis Modulate the Microbiota‐Gut‐Joint Axis for Rheumatoid Arthritis Therapy

open access: yesAdvanced Science, EarlyView.
A valence‐engineered CeOX nanozyme, with its Ce3+/Ce4+ ratio precisely controlled within the range of 0.27 to 0.93 through Au deposition, performs a self‐cascade oxidase‐superoxide dismutase‐peroxidase reaction, enabling continuous reactive oxygen species scavenging while minimizing oxygen generation.
