AI Article Synopsis

  • Intense ultraviolet light emission has been detected in tiny rhombic-shaped nanodisks made of YF3, which measure about 14 nm on each side and 2.5 nm thick.
  • These nanodisks are co-doped with Yb(3+) ions which act as a sensitizer and Tm(3+) ions which serve as an activator.
  • The emission occurs when these nanodisks are excited using light at approximately 980 nm.

Article Abstract

Intense ultraviolet upconversion emission has been observed in water-dispersed uniform rhombic nanodisks (side length of ~14 nm and thickness of ~2.5 nm) of YF3 co-doped with Yb(3+) sensitizer and Tm(3+) activator ions, when excited at ~980 nm.

Ultraviolet B (UVB) radiation is a major contributor to skin photoaging. Although mainly absorbed by the epidermis, UVB photons managing to penetrate the upper dermis affect human dermal fibroblasts (HDFs), leading, among others, to the accumulation of senescent cells. In vitro studies have shown that repeated exposures to subcytotoxic UVB radiation doses provoke HDFs' premature senescence shortly after the end of the treatment period.

The reduction of Cr(VI) to Cr(III) is key to lowering environmental toxicity and mobility, but the reverse process remains less understood. We investigated Cr(III) oxidation mechanisms across various pH levels and light wavelengths (185, 254, and 358 nm) in the presence of Fe(III). At pH 3.

Cationic Coordination Modification Drives Birefringence and Nonlinear Effect Double Lifting in Sulfate.

Inorg Chem

December 2024

Guangxi Key Laboratory of Electrochemical Energy Materials, School of Chemistry and Chemical Engineering, Guangxi University, Nanning, Guangxi 530004, China.

As nonlinear optical (NLO) crystals, sulfates have the superiority of transparency for ultraviolet (UV) light, but they are often troubled by small nonlinear coefficients and birefringence owing to the high symmetry of the [SO] group. By introducing two neutral diethylenetriamine (DETA) molecules to replace the six coordinated water molecules of the [Zn(HO)] complex cation in [Zn(HO)](SO)(HO), a new sulfate with an acentric structure, namely, [Zn(DETA)](SO)(HO), has been designed and synthesized. Structural investigation reveals that the coordination modification of Zn ion tremendously enhances its intraoctahedral distortion.

A New Optical Analysis System for Online Measurement of NO Temperature and Concentration in Combustion Processes.

Anal Chem

December 2024

Measurement Technology & Instrumentation Key Laboratory of Hebei Province, Institute of Electrical Engineering, Yanshan University, Qinhuangdao 066004, China.

In the combustion process, the nitric oxide (NO) concentration and temperature are considered to be highly related to the combustion efficiency. Currently, ultraviolet differential absorption optical spectroscopy (UV-DOAS) has become an ideal method for NO analysis due to its strong absorption characteristics in the UV spectral regime. However, since temperature and concentration have similar effects and complex correspondences on intensity, it is a challenge to achieve dual-indicator sensing of NO at this time.
