Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges
Advanced Functional Materials, EarlyView.Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.

Shaping of Biohybrid Functional Living Materials
Advanced Functional Materials, EarlyView.This work demonstrates a strategy for shaping living mycelium into functional materials by directing its natural growth. Nanoparticles armor hyphae, micron‐scale particles entangle within the network, and printed hydrogel architectures steer expansion, creating defined geometries.

Specific Normal Impedance and Sound Absorption Coefficients of Materials [PDF]
The Journal of the Acoustical Society of America, 1941 This paper reports the results of comparison measurements of “reverberation coefficients” made on identical samples of materials in three reverberation chambers, having volumes ranging from 10,000 to 15,000 cubic feet. The results of these measurements indicate that, in rooms of comparable size, discrepancies in the measured values of the ...
