Supramolecular salicylic acid ameliorates rosacea-like eruptions by suppressing NLRP3-mediated inflammasome activation in mice.

Background: Rosacea is a chronic inflammatory skin disease with immunological dysfunction. Supramolecular salicylic acid (SSA) has the properties of keratolytic, antibacterial, and anti-inflammatory. However, the mechanism of SSA in the treatment of rosacea is still unclear.

Ultraintense Zero-Phonon Line from a Mn Red-Emitting Phosphor for High-Quality Backlight Display Applications.

The zero-phonon line (ZPL) of Mn, which highly depends on its local environment, is usually much weaker than the vibrational phonon sidebands. In this work, an ultraintense ZPL emission, coming from a brand new red-emitting RbLiGaF:Mn (RLGFM) phosphor upon blue light excitation, is presented. The interesting spectral characteristic originates from the nonequivalent substitution of Mn for Ga in a rigid octahedral structure with a low symmetry, which induces neighboring cation vacancies that distort the local symmetry of the [MnF] octahedra.

Electronic and optical properties of a novel fluoroaluminate red phosphor CsNaAlF:Mn with high color purity for white light-emitting diodes.

In this work, a novel fluoroaluminate red phosphor of CsNaAlF:Mn with excellent color purity was fabricated via the introduction of Mn in the octahedral center. The crystal and electronic structures, luminescence properties and optical performances were characterized and investigated in detail. The evidences showed that CsNaAlF:Mn well-crystallized into a single phase with particulate morphology, and the non-equivalent occupation in CsNaAlF resulted in sharp red emissions with improved color purity upon blue light illumination.
