Advanced Functional Materials, EarlyView.Porous carbon host materials are investigated for their possible usage in liquid alkali‐metal negative electrodes. X‐ray computed tomography reveals pore‐filling behavior under various conditions: non‐wetting, forced wetting, and spontaneous wetting. The applicability of porous carbon in electrochemical cells is demonstrated at high areal capacities ...

Proteins, Processing, and Properties of Adhesive Fluid Condensates Purified from Mussels
Advanced Functional Materials, EarlyView.Mussels exhibit an unmatched proficiency for adhering to wet surfaces in salty environments—a remarkable ability that could inspire new biomedical and technical glues. The fluid protein condensates used to form the underwater mussel glue are extracted, reconstituted and characterized with advanced spectroscopy and nanomechanical analysis, revealing ...

Upcycling of Disposable Face Masks into Water‐Resistant and Flame Retardant Foams
Advanced Functional Materials, EarlyView.Disposable mask waste is upcycled into lightweight polypropylene‐based foams with tunable porosity and composite architectures reinforced by ear‐loop fibers. The sustainable solvent‐based process enables upcycling rates of 91% and solvent recovery of >90%.

Abstract An acoustically hard surface has reflection coefficient of +1 for all angles of incidence. A surface characterized by an impedance boundary condition, on the other hand, has a reflection coefficient which is a function of the angle of incidence. In particular, an impedance surface has a reflection coefficient of −1 at grazing

DURING research on the contact of solid surfaces we have been examining the deformation under load of single asperities. These are formed by turning cones of base diameter about 0.2 mm on metal surfaces and are pressed against a hard anvil under known loads. The resulting flats are examined by relocation profilometry1 and by optical microscopy.
