The Influence of Interfacial Chemistry on Magnesium Electrodeposition in Non-nucleophilic Electrolytes Using Sulfone-Ether Mixtures

Frontiers in Chemistry, 2019
One of the limiting factors in the development of magnesium batteries is the reversibility of magnesium electrodeposition and dissolution at the anode. Often irreversibility is related to impurities and decomposition.

Fabrication of Superinsulating Poly(Urethane‐Isocyanurate) Aerogels Derived from Upcycled Polycarbonate

Advanced Sustainable Systems, EarlyView.
Bisphenol‐A polycarbonate is upcycled via a simple one‐pot reaction into an aromatic Mannich polyol, which serves as a precursor for fabricating poly(urethane‐isocyanurate) (PUR‐PIR) aerogels. PUR‐PIR aerogels, prepared with different isocyanate indices, exhibit high porosities, high specific surface areas, ultralow thermal conductivity, and excellent ...

A Regenerative Redox‐Mediated Electrolysis System (RReMES) for Efficient Reduction of Water Electrolysis Overpotentials

Advanced Sustainable Systems, EarlyView.
A Regenerative Redox‐Mediated Electrolysis System (RReMES) is proposed, which enables hydrogen production at a significantly lower overpotential by mixing hydroquinone as a redox mediator compared to conventional water electrolysis utilizing the oxygen evolution reaction.

Peptide‐Based Biomaterials as a Promising Tool for Cancer Radiotherapy

Advanced Science, EarlyView.
This review provides a systematic overview of peptide‐based biomaterials in tumor radiotherapy, covering their roles as both radiosensitizers and radiopharmaceuticals. Peptide‐based radiosensitizers are generally divided into three categories: peptides as direct radiosensitizers, peptides as carriers of radiosensitizers, and targeted‐peptide‐modified ...
