Anomalous Glassy Thermal Conductivity in a Perovskite Bismuthate Induced by Structural Dynamic Instability

open access: yesAdvanced Science, EarlyView.
Unraveling the underlying mechanisms at the origin of ultra‐low thermal conductivity in pristine crystals is of central relevance to designing new functional materials. Single crystals of the candidate functional material BaBiO3 show an anomalous glassy thermal conductivity, which reveals the role of strong anharmonicity and additional scattering ...

Amyloid Forming Human Lysozyme Intermediates are Stabilized by Non‐Native Amide‐π Interactions

open access: yesAdvanced Science, EarlyView.
Mutational variants of human lysozyme cause fatal systemic amyloidosis by depositing kilograms of protein in the viscera of patients. Central to this process is a partially unfolded protein intermediate state that initiates aggregation into amyloid fibrils.

Phenylalanine‐Based DNA‐Encoded Chemical Libraries for the Discovery of Potent and Selective Small Organic Ligands Against Markers of Cancer and Immune Cells

open access: yesAdvanced Science, EarlyView.
FM‐DEL1 and FM‐DEL2 are constructed by installing one or two sets of building blocks on a phenylalanine central scaffold. FM‐DELs are screened against markers of prostate, and renal cell carcinoma, and against an immunological target expressed on the surface of natural killer cells.

Synaptic Function in Memristor Devices for Neuromorphic Circuit Applications

open access: yesAdvanced Electronic Materials, EarlyView.
Discover how neuromorphic devices mimic brain‐like learning: this article explores how ionic and electronic conduction processes enable artificial synapses to adapt across time scales. Uncover the essential ingredients—state‐variable dynamics, rectification, and memory—and how they can be probed through nonlinear diagnostics to engineer smarter, more ...
