Millisecond Spin Relaxation Times of Distinct Electron and Hole Subensembles in MAxFA1−xPbI3 Perovskite Crystals

open access: yesAdvanced Science, EarlyView.
Mixed‐cation MAx${\rm MA}_x$ FA1−x${\rm FA}_{1-x}$ PbI3${\rm PbI}_3$ perovskite crystals reveal multiple discrete electron and hole spin subensembles associated with distinct localization environments. Optically detected magnetic resonance combined with resonant spin inertia uncovers carriers spin relaxation times reaching 2 ms and identifies nuclear ...

Unveiling the Ultralow Thermal Conductivity of Hybrid Perovskites

open access: yesAdvanced Science, EarlyView.
In hybrid perovskites, thermal energy flows through lattice vibrations of the framework (48%–65%) and organic molecules (35%–52%). When the disorder introduced by organic molecules is excluded, the temperature dependence of the vibrational thermal conductivity results from the lattice framework transits from ∼T0 to ∼T−1, and the value doubles at room ...

This May, or May Not, Be an Ethics Consultation [PDF]

open access: yes, 2018
We begin with the acknowledgement that with “The Zadeh Scenario,” Finder has provided a rich and thick description of what clearly was a challenging opportunity for end-of-life ethics consultation. As such, his narrative now stands as opportunity for us to engage with him in the even more challenging opportunity of post-mortem moral reflection. We have

Spectral‐Kinetic Synergy in Au‐Network Engineered FeTiO3: A Multi‐Field Coupling Strategy for Lunar In Situ Resource Utilization

open access: yesAdvanced Science, EarlyView.
How can humanity achieve lunar self‐sufficiency? We utilize Au topology networks to modify the abundant lunar ilmenite. This catalyst, under sunlight, can convert waste carbon dioxide into space fuel. This design leverages the moon's natural vacuum for green manufacturing, avoiding the waste of gold and serving as “artificial chloroplasts” to sustain ...

Studies on Counter Electrode Materials in Aqueous Zinc Half‐Cell Configurations

open access: yesAdvanced Science, EarlyView.
Coulombic efficiency is a key metric for zinc reversibility in aqueous zinc‐ion batteries, but its reliability in zinc half‐cells is strongly influenced by poorly understood counter‐electrode materials. By systematically comparing Cu, Ti, stainless steel, and Al to identify reactions associated with current collectors, we find that Ti is the metal ...
