Aerosol Jet Printed MXene Microsupercapacitors for Flexible and Washable Textile Energy Storage

Advanced Functional Materials, EarlyView.
This study introduces a novel approach using aerosol jet printing to fabricate e‐textiles with additive‐free aqueous Ti3C2Tx MXene inks. The flexible electrodes, systematically explored on cotton, polycotton, and polyester, exhibit remarkable areal capacitances of up to 4.4 F cm−2, achieving superior high‐rate performance, capacitance retention, and ...

Brexit and Uncertainty in Financial Markets [PDF]

SSRN Electronic Journal, 2018
This paper applies long-memory techniques (both parametric and semi-parametric) to examine whether Brexit has led to any significant changes in the degree of persistence of the FTSE (Financial Times Stock Index) 100 Implied Volatility Index (IVI) and of the British pound’s implied volatilities (IVs) vis-à-vis the main currencies traded in the FOREX ...

Encapsulating Zinc Powder in MXene/Silk Scaffolds with Zincophilic‐Hydrophobic Polymer for Flexible Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
This work develops flexible zinc‐ion batteries (FZIBs) using a zincophilic/hydrophobic polymer (thermoplastic polycarbonate‐based polyurethane, TPCU) to protect Zn powder anodes and MXene/Silk (MXS) as flexible current collectors. The designed TPCU‐ZnP@MXS structure enables uniform Zn deposition, yielding dendrite‐free anodes with stable cycling ...

Defect Engineering on Commercial Carbon for Economical H2O2 Electrosynthesis Under Industrial‐Relevant Conditions

Advanced Functional Materials, EarlyView.
The implementation of electrocatalysts toward H2O2 electrosynthesis on an industrial scale necessitates the reconsideration of design criteria. The proposed “active sites saturation” theory shows that materials with mixed active sites normally exhibit low selectivity under practical conditions.

Harmonizing the Pyrene and Ether Groups in Covalent Triazine Polymers for Highly Effective H2O2 Photosynthesis via One‐Step Two‐Electron Oxygen Reduction

Advanced Functional Materials, EarlyView.
The pyrene and ether groups are incorporated into the covalent triazine polymer (CTP) structure. The synergistic effect of the two functional groups endows CTP with better electron transfer, light absorption, and oxygen activation properties. An impressive apparent quantum yield (13.2% @420 nm) and a remarkable solar‐to‐chemical conversion efficiency ...

Electrochemical Formation of BiVO4/BiPO4 Photoanodes for Enhanced Selectivity toward H2O2 Generation

Advanced Functional Materials, EarlyView.
In acidic KPi, V dissolves from the BiVO4 lattice, while adsorbed phosphate reacts with the electrode under an external bias, forming a BiPO4 surface layer. This BiPO4 layer exhibits stronger bicarbonate adsorption, redirecting the water oxidation pathway toward two‐electron H2O2 production.
