Macrophages Mediate Mesoscale Brain Mechanical Homeostasis
We investigated the role of infiltrating immune cells in sculpting the developing brain. Using Brillouin microscopy and active microrheology, we found microglia actively maintain tissue viscoelasticity. Moreover, colony stimulating factor one receptor (CSF1R)‐driven stromal remodeling alters brain mechanics in vivo. These findings link immune activity,

Encapsulation of a fiber taper coupled microtoroid resonator in a polymer matrix
We encapsulated a high-quality (Q) factor optical whispering gallery mode (WGM) microtoroid resonator together with its side coupled fiber taper inside a low refractive index polymer, achieving a final Q higher than 10^7.

Continuous‐wave lasing from a small number of perovskite quantum dots is achieved by coupling their photoluminescence to open‐access curved dielectric cavities. This geometry confines their emission into a single optical mode, sharply narrowing linewidths in both spontaneous and lasing regimes.

Nonlinear orbital angular momentum (OAM) manipulation is crucial for fundamental physics and information technologies. An integrated lithium niobate platform combining Bragg diffraction and birefringent phase matching asymmetrically generates and controls second‐harmonic OAM beams, achieving a normalized conversion efficiency of 10−2 W−1 and supports a

Real‐Time Nanopositioning for Security Holograms [PDF]
AbstractAn embedded vision system computes position data in real time and controls a nanopositioning system, ensuring that the optics in a microlithography system always stay in focus and enabling the creation of high‐tech master holograms for holographic security seals and labels.

The thermal conversion of the single‐source precursor Mn(H2C3N3O3)2(H2O)4 reveals a sequence of new compounds. One intermediate compound is the second‐harmonic‐generation‐active Mn(HC3N3O3) (MHCY) that appears before pure Mn(CN2) is formed. Two manganese cyanurate compounds, Mn(H2C3N3O3)2(H2O)4 and Mn(H2C3N3O3)2(H2O)7 were prepared and structurally ...
