Rational Tuning of Hygroscopic Oscillation of Stacked Nanoflake Assemblies for Continuous Ambient Energy Harvesting

open access: yesAdvanced Materials, EarlyView.
Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...

Human ecological genetics

open access: yesEcological genetics, 2003
A resumptive review of the three types of effects of new environmental factors on human heredity is presented: 1) alteration of hereditary elements (induced mutagenesis); 2) pathological manifestations of gene expression on the specific environmental factors (ecogenetic diseases, pharmacogenetics, toxicogenomics, nutrigenomics); 3) alteration of the ...

Operando X‐Ray Absorption Spectroscopy Reveals Dynamic Interfacial Metal–Metal Coordination Governing CO2 Reduction Selectivity in PdAg Alloys

open access: yesAdvanced Materials Interfaces, EarlyView.
Operando X‐ray absorption spectroscopy uncovers dynamic Ag–Pd coordination in PdxAg1−x electrocatalysts during CO2 reduction. Partial oxidation of Ag and composition‐dependent metal–metal bonding synergistically regulate intermediate binding, enabling ∼91% CO selectivity.
