Advanced Functional Materials, EarlyView.Circular photogalvanic effect measurements and first‐principles calculations reveal spin‐splitting states in solution‐processed bournonite films (CuPbSbS3) due to structural and bulk inversion asymmetry. The results provide experimental confirmation of coexisting Rashba and Dresselhaus spin‐splitting states in this non‐centrosymmetric chalcogenide ...

SOME FORENSIC ASPECTS OF BALLISTIC IMAGING [PDF]
, 2010 Analysis of ballistics evidence (spent cartridge casings and bullets) has been a staple of forensic criminal investigation for almost a century. Computer-assisted databases of images of ballistics evidence have been used since the mid-1980s to help ...

Scalable Thermal Engineering via Femtosecond Laser‐Direct‐Written Phononic Nanostructures
Advanced Functional Materials, EarlyView.This study demonstrates that femtosecond laser‐induced periodic surface structures (fs‐LIPSS) can function as phononic metasurfaces, reducing thermal conductivity below the plain thin‐film limit. Phonon Monte Carlo analysis reveals that the periodic structures restrict phonon mean free paths.

Nanolayer‐Encapsulated Stretchable Liquid‐Metal Sheets for Thermal Management
Advanced Functional Materials, EarlyView.A stretchable liquid metal sheet with both high thermal conductivity and mechanical flexibility is developed. Its trilayer structure, comprising copper‐particle‐dispersed gallium liquid metal encapsulated by styrene‐butadiene‐styrene nanosheets, shows 40.4 W m−1 K−1 conductivity, elongation exceeding 200%, and retention of 96% of its initial ...

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.
