Advanced Materials Technologies, EarlyView.In situ, nanoparticle doping enhances the piezoelectric coefficient (**d₃₃**) of PVDF to ≈12 pC/N, while in situ growth of AgF and Ag₂O dopants increases β‐phase concentration. The nanogenerator achieves a 35 V open‐circuit voltage and 1.6 µA short‐circuit current, powering 10 blue LEDs and charging a 50 nF capacitor within 10 s.

Evolution of Lithium-Beryllium-Boron and Oxygen in the early Galaxy [PDF]
, 2001 Oxygen is a much better evolutionary index than iron to describe the history of Lithium-Beryllium-Boron (LiBeB) since it is the main producer of these light elements at least in the early Galaxy.

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.This article presents a hybrid metal‐dielectric metasurface in transmission mode for mid‐infrared (MIR) spectroscopy. Composed of germanium on aluminium cylinders atop a calcium fluoride substrate, the metasurface achieves 80% transmission efficiency at λ = 2.6 µm with a narrow full‐width‐half‐maximum of 0.4 µm.

A Dual‐Emissive DNA‐Templated Silver Nanocluster with Near‐Infrared I and II Emission
Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.This study presents a dual‐emissive DNA‐stabilized silver nanocluster with a nanosecond‐lived NIR‐I emission band and a microsecond‐lived NIR‐II emission band. Mass spectrometry establishes that the nanocluster has molecular formula (DNA)2[Ag17]11+. DNA sequence variations reveal critical nucleobases for stabilization, and modifications at the DNA 5 ...
