Non-equilibrium chemistry and dust formation in AGB stars as probed by SiO line emission

, 2007
We have performed high spatial resolution observations of SiO line emission for a sample of 11 AGB stars using the ATCA, VLA and SMA interferometers. Detailed radiative transfer modelling suggests that there are steep chemical gradients of SiO in their ...

ZnO‐Coated Silicon Oxide Nano‐Anode: Synergistic Enhancement of Cycling and Thermal Stability of Lithium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Lithium‐ion battery anodes that maintain good performance and excellent stability under high temperature conditions. Silicon oxide (SiO) has great potential as a high‐capacity anode for lithium‐ion batteries, but its practical use is limited by excessive volume expansion (>200%) and rapid capacity fade, especially at high temperatures.

High‐mobility suspended MoS2 devices with tunable threshold voltage

InfoMat, EarlyView.
Due to their atomic‐scale thickness, two‐dimensional materials (2DMs) are highly sensitive to their environment, including the substrate. By fabricating various suspended molybdenum disulfide devices, this study demonstrates that the suspended structure can shield the influence of the substrate on the properties of 2DMs, thereby enabling better ...

Empowering Adolescents for Sustainable and Inclusive Careers: A Quasi‐Experimental Evaluation of a Life Design‐Based Intervention

Journal of Adolescence, EarlyView.
ABSTRACT Background Adolescents must plan their educational and occupational futures in a context shaped by globalization, social inequalities, and environmental crises. Although career guidance increasingly emphasizes sustainable and inclusive development, empirical interventions integrating social justice, sustainability, and critical consciousness ...
