Experimental Validation of Diffraction Lithography for Fabrication of Solid Microneedles

Description: Article states that microneedles are highly sought after for medicinal and cosmetic applications. However, the current manufacturing process for microneedles remains complicated, hindering its applicability to a broader variety of applications. This experimental study enables the shapes and mechanical properties of the microneedles to be predicted in advance for mass production and wide practical use for biomedical or cosmetic applications.

Quantum Emitters Induced by High Pressure and UV Laser Irradiation in Multilayer GaSe

Description: Article shows that hydrostatic‑pressure quenching and UV‑laser irradiation generate distinct but partially overlapping defect states in multilayer GaSe, producing characteristic low‑temperature photoluminescence peaks and revealing broader defect‑energy distributions under UV irradiation. Article demonstrates shared single‑photon–emitter‑like features, distinct fluorescence lifetimes, and defect levels consistent with Se vacancies, providing insight into defect formation pathways in GaSe.
