Gold‐Stabilized Copper Enables Anodic Hydrogen Evolution for Ultralow‐Voltage CO‐to‐Ethylene Electrolysis

open access: yesAdvanced Materials, EarlyView.
Gold‐stabilized copper suppresses hydroxide‐driven deactivation during anodic hydrogen evolution from furfural. Pairing this low‐potential anode with CO‐to‐ethylene electroreduction enables sub‐1 V operation at 400 mA cm−2, high single‐pass CO conversion, and co‐production of ethylene, furoic acid, and a separate hydrogen stream.

Specific Position of Halogen in Crystalline TADF Scintillators Enables Efficient Triplet Harvesting Through Vibrational Modulation of Spin–Orbit Coupling

open access: yesAdvanced Materials, EarlyView.
Specific ortho‐halogenation transforms crystalline TADF emitters into efficient organic scintillators. Fluorine reduces the effective singlet–triplet separation, while chlorine combines near‐degenerate excited states with vibrational modulation of spin–orbit coupling.

Wearable Morphology‐Adaptive in‐Ear Device With Active Cleansing Capability for Multimodal Health Monitoring

open access: yesAdvanced Materials, EarlyView.
We present SCIENCE, an in‐ear multimodal physiological monitor featuring two key innovations. Water‐triggered morphological expansion (a 2‐mm cylinder to a 9‐mm spindle) achieves conformal adaptation across complex canal geometries. Simultaneously, active biofouling mitigation disrupts cerumen barriers, reducing sensor‐skin impedance by 20%.

Sonorism

2020
In this chapter, the use by twentieth-century composers of tone color, or timbre is explained with examples by those who made its use central to their compositional output. Poland, freed from the bonds of communism and the Soviet state, relaxed controls over the arts and in 1956 initiated the Warsaw Autumn festival where avant-garde Polish and Western ...

A Reexamination of the Feature [Sonorant]: The Status of ‘Sonorant Obstruents‘

Language, 1993
This paper argues for a feature called Sonorant Voice (SV), which replaces the traditional feature [sonorant]. It is underlyingly present in all sonorants and in obstruents that function as sonorants within a system. This feature differs from [sonorant] in several ways: (a) it defines the type of voicing present in sonorants, (b) it can be present in ...
