Melanin's Role in Balancing Mechanical Strength and Reproductive Output in Environmentally Stressed Fungal Spores

Advanced Functional Materials, EarlyView.
Melanin content directly controls fungal spore mechanical properties, with pigmented spores achieving rupture forces two orders of magnitude higher than hyaline spores. Environmental stress drives this quantity‐quality tradeoff; stressed species invest energy in melanin‐reinforced, mechanically superior thick‐walled, super‐hydrophobic spores, while ...

Electrically Induced Phase Transition and Synaptic Functionality in MoTe2/Graphene Memristors

Advanced Functional Materials, EarlyView.
An electrically induced reversible 2H ↔ 1T′ phase transition is demonstrated in a vertical Au/Ti/MoTe2/graphene memristor with a laterally contacted graphene electrode. Resistive switching proceeds through a compositionally invariant amorphous/2H ↔ amorphous/1T′ transformation, in which a self‐formed amorphous MoTe2 interfacial region is proposed to ...

Rapid Microwave Plasma Engineering of HfO2/C@C Core‐Shell Fibrous Membrane Toward Flexible High‐Performance Electromagnetic Wave Absorption

Advanced Functional Materials, EarlyView.
Rapid microwave plasma torch engineering tunes crystal phases, carbon graphitization and oxygen‐vacancy defects in HfO2/C@C core‐shell fibrous membranes. Synergistic multi‐loss effects optimize impedance matching to deliver −65.75 dB reflection loss and a 7.37 GHz effective bandwidth for flexible electromagnetic wave absorption.
