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

Advanced 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 ...

Yellow fever outbreak in Brazil: the puzzle of rapid viral spread and challenges for immunisation

Memórias do Instituto Oswaldo Cruz, 2018
We discuss the complex eco-social factors involved in the puzzle of the unexpected rapid viral spread in the ongoing Brazilian yellow fever (YF) outbreak, which has increased the reurbanisation risk of a disease without urban cases in Brazil since 1942 ...

Fast pH‐Driven Solubilization Method of Realgar (As4S4) to Reduce the Toxicity of Arsenic [As(III)] for Medicinal Purposes

Advanced Science, EarlyView.
Arsenic trioxide transformed acute promyelocytic leukemia therapy and shows promise against HIV. A new method to solubilize the mineral realgar produces different arsenic species depleting the main arsenic target, nuclear PML protein, and retaining effects on leukemic and HIV reservoir cells, while minimizing off‐target damage.

Wearable Bioelectronics for Home‐Based Monitoring and Treatment of Muscle Atrophy

Advanced Science, EarlyView.
As an inevitable disease, muscle atrophy has received more attention. Because the factors that induce this disease are diverse, achieving a complete cure is still impossible. Wearable bioelectronics provides a more comfortable, low‐cost, and efficient way of home care for the monitoring and treatment of muscle atrophy. Therefore, this review summarizes

Regular and Inverted Hysteresis in Organic Electrochemical Transistors: Mechanisms and Electrochemical Insights

Advanced Electronic Materials, EarlyView.
In organic electrochemical transistors, the switch from regular to inverted hysteresis in the transfer curve is driven by how ions move in and out of the mixed electronic‐ionic semiconductor. This behavior is tightly linked to the open‐circuit potential (OCP) at the electrolyte–semiconductor interface, with scan speed determining whether ion dynamics ...
