Metal‐Ion Regulated Light‐Free Z→E Isomerization of Azobenzene Glycomacrocycle

Chemistry – A European Journal, EarlyView.
Metal ion‐catalyzed Z→E isomerization of photoswitchable azobenzene glycomacrocycle: A new azobenzene‐based glycomacrocycle is capable of forming a 1:1 complex with divalent metal ions in both E‐ and Z‐isomers. The complexes undergo light‐free Z→E isomerization in a timescale spanning from seconds to weeks.

Dynamics of cavitation bubbles in a liquid layer

Droplet, EarlyView.
The dynamics of cavitation bubbles within a liquid layer is studied experimentally. Due to the combined effect of the rigid wall and free surface, the bubbles exhibit a significant downward migration. The confinement effect of the rigid wall significantly affects the bubble's collapse morphology, leading to different post‐collapse phenomena of free ...

Instability mechanism and failure characteristics of underground cavern in block system under the action of seismic waves

Deep Underground Science and Engineering, EarlyView.
Seismic waves with tensile stress, high amplitude, and low frequency are most likely to trigger block instability and sliding. Blocks with a single sliding surface are more prone to movement than those with multiple constraints, and roof‐positioned blocks are especially vulnerable to slide.

A Thermally Robust Luminescent Antimony Halide for Real‐Time Detection of Volatile Iodine at Elevated Temperatures

EcoEnergy, EarlyView.
Zero‐dimensional antimony halides drive efficient iodine capture through electron transfer and display rapid fluorescence quenching at 75°C (348 K), establishing the first luminescent sensor for real‐time I2 detection at elevated temperatures. ABSTRACT Real‐time monitoring of volatile molecular iodine (I2), a hazardous radioactive byproduct of nuclear ...

Topography constrains the climatic response of treeline migration in Taiwan's subalpine forests

Ecography, EarlyView.
Treelines are moving upslope, but the rates and drivers differ among different regions, globally. Many studies have examined the relationship between treeline movement and climate change, particularly rising temperature, while the role of topographical factors has received much less attention, despite the longstanding recognition of its importance.
