Thermal holographic patterns for ultrasound hyperthermia [PDF]
, 2022 [EN] Holograms can shape wavefronts to produce arbitrary acoustic images. In this work, we experimentally demonstrate how acoustic holograms can produce controlled thermal patterns in absorbing media at ultrasonic frequencies. Magnetic resonance imaging (

Novel Non‐Cytotoxic Acylphosphinates and Acylphosphine Oxides Photoinitiators
Angewandte Chemie, EarlyView.Novel acylphosphine oxide (APO) and acylphosphinate photoinitiators based on DPO and DOPO were designed to investigate structure–property relationships including photochemical performance, polymerization efficiency and cytotoxicity. While DPO derivatives showed excellent reactivity, DOPO‐based systems also displayed good efficiency and significantly ...

Full degree-of-freedom polarization hologram by freeform exposure and inkjet printing
PhotoniX, 2023 Since the invention of holography by Dennis Gabor, the fabrication of holograms has mainly relied on direct recording of wavefront by engraving the intensity fringes of interfering electric fields into the holographic material. The degree-of-freedom (DoF)

Advanced Materials, EarlyView.We report a multifunctional tapered optical fiber integrating a conformal micro‐resistance temperature detector (µRTD) for local, real‐time thermometry during optical stimulation. The platform combines light‐delivery and temperature sensing within a minimally invasive footprint, enabling detection of sub‐degree cortical heating under representative ...
