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

Advanced 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 ...

A single-chip false target radar image generator for countering wideband imaging radars

IEEE Journal of Solid-State Circuits, 2002
This paper describes the theory, design, implementation, simulation, and testing of an ASIC capable of generating false target radar images for countering wideband synthetic aperture and inverse synthetic aperture imaging radars. The 5.5 /spl times/ 6.1 mm IC has 81632 transistors, 132 I/O pins, and consumes 0.132 W at 70 MHz from a 3.3-V supply.

Novel Antifungal Scaffold Targeting Tubulin Overcomes Sclerotinia Sclerotiorum Resistance

Advanced 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.

Metasurfaced Reverberation Chamber

Scientific Reports, 2018
The concept of metasurfaced reverberation chamber (RC) is introduced in this paper. It is shown that by coating the chamber wall with a rotating 1-bit random coding metasurface, it is possible to enlarge the test zone of the RC while maintaining the ...

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

Advanced 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.
