New design strategy for acoustic holograms demonstrates potential for biomedical applications
The inability of acoustic holograms to independently modulate both phase and amplitude of incident waves is circumvented by multiple phase holograms designed using an iterative Fourier transform algorithm.
Nanocalorimetry review explores the past and future of the technique
Nanocalorimetry has successfully measured small-scale, high-speed thermal properties in sub-monolayer films and surface reactions and may be used to study metastable and epitaxial materials in the future.
Two methods developed for efficiently reproducing kinetic properties in molecular systems
