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.

The average transmitted wave in random particulate materials
New Journal of PhysicsMicrowave remote sensing is significantly altered when passing through clouds or dense ice. This phenomenon is not unique to microwaves; for instance, ultrasound is also disrupted when traversing through heterogeneous tissues.

Electromagnetic wave scattering and resonances in a complex plasma
Advances in Physics: X, 2017 The electromagnetic wave propagation in a complex plasma containing macroparticle inclusions (dust) is reviewed. We focus on two classes of phenomena due to the presence of dust: (1), collection of plasma electrons and ions by macroparticle inclusions ...

Advanced Functional Materials, EarlyView.Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.

Color Routing and Beam Steering of Single‐Molecule Emission with a Spherical Silicon Nanoantenna
Advanced Functional Materials, EarlyView.We experimentally demonstrate broadband directional emission from single molecules using a single spherical silicon nanoparticle assembled via DNA origami. By varying nanoparticle (NP) size and emitter position, we achieve unidirectional emission, beam steering, and color routing at the nanoscale, revealing modal interference as the underlying ...

Supersharp resonances in chaotic wave scattering [PDF]
Physical Review E, 2012 Wave scattering in chaotic systems can be characterized by its spectrum of resonances, $z_n=E_n-i\frac{ _n}{2}$, where $E_n$ is related to the energy and $ _n$ is the decay rate or width of the resonance. If the corresponding ray dynamics is chaotic, a gap is believed to develop in the large-energy limit: almost all $ _n$ become larger than some $ $
