A Sustainable and Low‐Cost Zn‐Lignosulfonate Redox Flow Battery

Batteries &Supercaps, EarlyView.
A cost‐effective Zn/lignosulfonate (NaLS) hybrid flow battery using 20 kDa NaLS delivers 3.52 Ah L−1 at 30 mM, with an average discharge voltage of 1.01 V, outperforming smaller NaLS. This sustainable design leverages industrial and bio‐based lignosulfonates, cheaper size exclusion membrane, and abundant Zn for ecofriendly, scalable energy storage ...

SPE-UHPLC-FLD Method for the Simultaneous Determination of Five Anthraquinones in Human Urine Using Mixed-Mode Bis(tetraoxacalix[2]arene[2]triazine) Modified Silica as Sorbent

Journal of Analytical Methods in Chemistry, 2017
The five anthraquinones compounds (including aloe-emodin, emodin, physcion, chrysophanol, and rhein) are regarded as the main effective ingredients in rhubarb (Dahuang in Chinese, one of the commonly used Chinese herbal medicines). In this work, a simple

Regulating Interfacial Hydrogen‐Bonding Connectivity by Oxygen Vacancies‐Driven [Fe(CN)6]3− Coordination for Boosting Hydrogen Peroxide Electrosynthesis

Carbon Energy, EarlyView.
ABSTRACT The inherent hydroxide‐rich (OH⁻) environment in alkaline media facilitates the two‐electron oxygen reduction reaction (2e−ORR). However, the strong interaction between alkali metal cations and solvated water molecules significantly reduces the connectivity of the hydrogen bond network within the alkaline electric double layer, thereby ...

Rh‐Catalyzed [2 + 2 + 2] Cycloaddition of Linked Bis(Diynes) Ar‐C≡C‐C≡C‐(CH2)3‐C≡C‐C≡C‐Ar With Quinones: Synthesis and Photophysical Properties of Bis(Arylethynyl)‐Naphthoquinones and Anthraquinones

Chemistry – A European Journal, EarlyView.
We report the synthesis bis(arylethynyl)naphtho‐ and anthraquinones via Rh(I)‐catalyzed [2 + 2 + 2] cycloaddition reactions. The substrate scope of both quinones and linked bis‐diynes was explored. Microwave irradiation remarkably enhanced yields.

Photoelectrochemical Hydrogen Peroxide Production via Simultaneous Reduction and Oxidation Processes

Chemistry – A European Journal, EarlyView.
Hydrogen peroxide (H2O2) is an important chemical substance and also a promising carbon‐free clean fuel. The design of a sophisticated photoelectrochemical (PEC) reaction system enables the solar‐driven H2O2 production through simultaneous water oxidation and oxygen reduction processes (H2O2/H2O2‐PEC cells).
