TL;DR: The fabrication of pure and stable hexagonal silicon evidenced by structural characterization is demonstrated, which opens the way for exploring its optical, electrical, superconducting, and mechanical properties.

TL;DR: In this paper, the authors studied the Raman spectrum of graphene under ultrafast laser excitation with 3'ps pulses, which trade-off between impulsive stimulation and spectral resolution.

TL;DR: In this article, the electronic and molecular structure of noble metal nanoparticles (AgNPs, AuNPs) stabilized by the negatively charged hydrophilic organic thiol Sodium 3-mercapto-1-propanesulfonate (3-MPS) was probed combining Synchrotron Radiation-induced X-ray Photoelectron Spectroscopy (SR-XPS) and Surface Enhanced Raman Spectrograph (SERS).

TL;DR: The detailed characterization of a case study SERS-active pH nanosensor, based on the conjugation of gold nanoparticles with the pH-sensitive molecular probe 4-mercaptobenzoic acid (4MBA), which was successfully employed to measure the extracellular pH of normal and cancer cells, demonstrating the capability to discriminate between them.

TL;DR: The Raman spectrum of graphene under ultrafast laser excitation with 3 ps pulses is studied, which trade off between impulsive stimulation and spectral resolution, important for the emerging field of graphene-based photonics and optoelectronics.
