Impact of photochemical ageing on Polycyclic Aromatic Hydrocarbons (PAH) and oxygenated PAH (Oxy-PAH/OH-PAH) in logwood stove emissions

Science of The Total Environment, 2019
The combustion of spruce logwood in a modern residential stove was found to emit polycyclic aromatic hydrocarbons (PAH) and oxygenated polycyclic aromatic hydrocarbons (OPAH) with emission factors of 404 μg MJ-1 of 35 analysed PAH, 317 μg MJ-1 of 11 analysed Oxy-PAH and 12.5 μg MJ-1 of 5 analysed OH-PAH, most of which are known as potential mutagens ...

Ion Concentration and Voltage Imaging With Fluorescent Nanodiamonds

Advanced Materials, EarlyView.
We demonstrate reversible switching between the fluorescent NV0 and the dark NV+ state, in sub‐30 nm FNDs via surface oxidation and hydrogenation, respectively. In an electrochemical cell, we show that the fluorescence from hydrogenated particles enables all‐optical imaging of voltages and ion concentrations at the micrometer scale.

Regioselective π‐Extension of Helical PAHs: Tuning Energy Gaps and Excited‐State Dynamics Directed by Clar's Sextet Migration

Advanced Optical Materials, EarlyView.
Central and terminal ring fusions of per‐peri‐perbenzo[7]helicene (PB[7]H) yield novel helical polycyclic aromatic hydrocarbons (HPAHs). The migration of Clar's aromatic sextets governs the inner‐rim stiffness. This topology‐directed strategy bridges the discrete optical gaps of homologous series. Transition moment density (TMD) analysis visualizes the

Quantum interference comparison between benzene, naphthalene, and azulene single molecular junction. [PDF]

مجلة جامعة الانبار للعلوم الصرفة
The ability to build devices from single-molecular junctions depends on the fabrication of molecular structures. Here we report significant changes in the transmission coefficient for different connectivities for polycyclic aromatic hydrocarbons (PAHs ...

A Modular Standard Operating Procedure for Standardizing Lithium Metal Interfaces

Advanced Science, EarlyView.
A modular standard operating procedure (SOP) is developed to standardize lithium metal interfaces through sequential etching, brushing, and soaking. By transforming poorly controlled lithium surfaces into chemically uniform and structurally regulated interfaces, the framework improves electrochemical reproducibility, interfacial stability, and ...
