Advanced Materials Technologies, Volume 11, Issue 9, 6 May 2026.Combined approach of electromagnetic (Power) and ultrasound (data harvesting) waves is proposed to address the miniaturized ultrasonic implants. Electromagnetic waves trigger the piezoelectric element to generate the acoustic pulse which is modulated by the variations in the sensor's impedance.

Investigation on the wavefront stability of wavefront sensors
, 2006 This dissertation mainly describes the wavefront stability of light source for the wavefront sensing systems. Several investigations on three different light sources, white light, laser diode and He-Ne laser have been carried out for two wavefront sensing systems, Hartmann and Shack-Hartmann systems.

Deep Volumetric Super‐Resolution Imaging in Thick Biological Specimens With Sparse Scanning SIM
Advanced Science, Volume 13, Issue 25, 4 May 2026.Sparse scanning structured illumination microscopy (SS‐SIM) extends the axial depth in super‐resolution fluorescence imaging by combining rapid laser scanning, pixel‐addressed intensity modulation, and sCMOS camera detection. SS‐SIM yields 1.6× lateral and 1.7× axial resolution gains over wide‐field microscopy and enables imaging through 300–600 µm ...

Metasurfaces and Metadevices for Topological Electromagnetic Waves
Advanced Physics Research, Volume 5, Issue 5, May 2026.Optical topologies refer to diverse topological localized structures made by diverse parameters of light fields, such as vortices, skyrmions, and hopfions. This article navigates a direction of metasurface‐based integrated devices for generation, manipulation and detection of novel topologies of light, which would be a rapidly growing interdisciplinary

Metalens‐Enabled Twisted Chromatic Dispersion
Advanced Physics Research, Volume 5, Issue 5, May 2026.We successfully demonstrate visible broadband twisted dispersion metalenses. As a proof of concept, we realized two distinct devices: the conical helical and the spring‐like dispersion‐controlled metalenses. These results rigorously validate the universality of our approach in customizing arbitrary continuous 3D dispersion trajectories, thereby ...

Conservation of Neuron‐Astrocyte Correlated Activity in Developing Sensory Pathways
Glia, Volume 74, Issue 5, May 2026.Astrocytes and neurons in the superior colliculus exhibit spatiotemporal correlated activity before eye opening. Each neuronal wave is followed by a calcium wave in astrocytes. Spillover of glutamate activates mGluR5 and mGluR3 in astrocytes. ABSTRACT Neurons in developing sensory organs exhibit prolonged burst firing before the onset of sensory ...
