Metabolomic profiling reveals systemic metabolic disruptions induced by combined exposure to particulate matter and ozone

Current Research in Toxicology
Air pollution exposure, especially particulate matter (PM) and ozone (O3), poses significant health risks, but the systemic metabolic consequences of combined exposures to PM and O3, remain poorly understood.

2D Indium Oxide at the Epitaxial Graphene/SIC Interface: Synthesis, Structure, Properties, and Devices

Advanced Materials, EarlyView.
A new monolayer insulator, InO2, is synthesized by intercalating indium beneath patterned epitaxial graphene on SiC, followed by high‐temperature oxidation. This selective confinement yields large‐area, uniform InO2 with a wide bandgap of 4.1 eV. Upon intercalation, the EG/n‐SiC junction transitions from ohmic to Schottky, exhibiting a rectification ...

Two‐Phase Rubber–Plastic Matrices’ Stabilization of Organic Room‐Temperature Phosphorescence Afterglows Better than Plastic Matrix

Small Structures, 2023
The rigid yet polar polymers as matrices for organic‐doped room‐temperature phosphorescence (RTP) polymers are widely reported, but nonpolar rigid plastics such as polystyrene (PS) are thought to be ineffective matrix and rarely attempted.

Review of Organic Persistent Phosphors: Classifications by Material Forms, Applications, and Mechanisms

Advanced Optical Materials, EarlyView.
Persistent luminescence (PersL), or afterglow, is the phenomenon of light emission that continues long after the excitation source is removed. This review systematically covers the historical development and major material forms of organic PersL materials, detailing their operating principles, mechanisms, and typical applications.

Covert Channel in RTP Payload Using a Pointer in Sip Header

Communications, 2016
The paper addresses the issue of hiding data in the network flow. The authors discuss a new proposal of the steganographic approach in IP telephony: transmitting texts using the pointer in the SIP header by means of a data stream within the RTP protocol.

Host‐Guest Doping Enables Room Temperature Phosphorescence from Triarylboranes

Angewandte Chemie, EarlyView.
While pure triarylboranes show RTP in annealed PMMA films, they do not in crystalline form, contrary to our previous report. However, crystalline host‐guest triarylborane systems show persistent afterglow up to 8 s even at 1 ppb guest loading. Computations identify triplet‐triplet energy transfer as the mechanism governing this efficient RTP.
