Presentism and Quantum Gravity [PDF]

, 2001
There is a philosophical tradition of arguing against presentism, the thesis that only presently existing things exist, on the basis of its incompatibility with fundamental physics.

Understanding Operando Water Management in Hydroxide‐Exchange‐Membrane Fuel Cells

Advanced Materials Interfaces, EarlyView.
Effective water management is vital for high‐performance hydroxide‐exchange‐membrane fuel cells. Using a custom water‐flux station, this study quantifies how membrane thickness, microporous layers, and operating conditions dictate internal water transport.

Smart Electrospun Nanofibers for Controlled Oil‐Water Separation

Advanced Materials Interfaces, EarlyView.
Stimuli‐responsive electrospun nanofibers are reviewed as advanced platforms for controlled oil/water separation. The effects of surface wettability, porous structure, and external stimuli, including pH, temperature, gas, and light, on separation performance are discussed.

Programming Light‐Driven Surface Topographies in Liquid Crystal Elastomers for Potential Biomedical Applications Through Combined Experiments and Simulations

Advanced Materials Technologies, EarlyView.
A combined experimental and simulation study of light‐responsive liquid crystal elastomer surfaces operating under physiological conditions is reported, demonstrating programmable and highly spatially controlled topography formation through bottom‐side photomask exposure. Our study establishes a foundation for dynamic, light‐responsive biosurfaces with

A Cryopreservation‐Based Supply Chain Strategy for Extrusion Bioprinting in Space

Advanced Materials Technologies, EarlyView.
Extrusion bioprinting on crewed space platforms requires a bioink that stays functional along the logistic chain. Here, cells and biomaterial ink travel separately, the cells cryopreserved and the ink cold stored, and are combined only minutes before printing.

UCST‐Driven Shape Morphing in Digital Light Processing 4D‐Printed Hydrogels

Advanced Materials Technologies, EarlyView.
A DLP‐printable UCST hydrogel based on poly(acrylic acid‐co‐acrylamide) enables reversible thermally induced expansion and 4D shape morphing. Rational control of composition, porosity, and multimaterial architecture enables predictable 4D shape morphing through differential swelling and localized actuation, opening new opportunities for high‐resolution

Structure and mechanical properties of iron foil electrodeposited in super gravity field

, 2010
The effects of super gravity field on the structure and the mechanical properties of iron foils electrodeposited were investigated by scanning electronic microscopy (SEM), X-ray diffraction (XRD) and atomic force microscopy (AFM). The results showed that
