Geometrically‐Screened, Sterically‐Hindered Additive for Wide‐Temperature Aqueous Zinc‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A molecular‑engineering strategy combining steric hindrance tuning with geometric optimization identifies cellobiose as an ideal additive for aqueous zinc‑ion batteries, enabling stable Zn deposition across a wide temperature range from −30 to 50 °C. Abstract Aqueous zinc‐ion batteries (AZIBs) are emerging as a highly promising alternative to lithium ...

The JT9D Jet Engine Diagnostics Program [PDF]

open access: yes
The various engine deterioration phenomena that affect JT9D performance retention were studied, and approaches to improve performance retention of engines were identified. The program included surveys of historical data, monitoring of in service engines,

Enhancing Synaptic Plasticity and Multistate Retention of Organic Neuromorphic Devices Using Anion‐Excessive Gel Electrolyte

open access: yesAdvanced Functional Materials, EarlyView.
Anion‐excessive gel‐based organic synaptic transistors (AEG‐OSTs) that can maintain electrical neutrality are developed to enhance synaptic plasticity and multistate retention. Key improvement is attributed to the maintenance of electrical neutrality in the electrolyte even after electrochemical doping, which reduces the Coulombic force acting on ...

Silver Ion‐Mediated [hk1]‐Oriented Sb2Se3 Crystal Growth for Efficient Photoelectrochemical Hydrogen Evolution

open access: yesAdvanced Functional Materials, EarlyView.
Ag+‐mediated hydrothermal crystal engineering promotes preferential [hk1]‐oriented growth of Sb2Se3 via an ultrathin MoOx interlayer, improving crystallinity and suppressing non‐radiative recombination. The optimized Ag+ treatment photocathode delivers 24.7 mA cm−2 at 0 VRHE and improved stability, revealing an ion‐modulated route to high‐performance ...

A comparison of visual and haltere-mediated equilibrium reflexes in the fruit fly Drosophila melanogaster [PDF]

open access: yes, 2003
Flies exhibit extraordinary maneuverability, relying on feedback from multiple sensory organs to control flight. Both the compound eyes and the mechanosensory halteres encode angular motion as the fly rotates about the three body axes during flight ...
