Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films

Advanced Functional Materials, EarlyView.
Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...

Micro-EDM Pulse Energy Distribution Ratio Determination

, 2013
In this paper, a pulse energy distribution ratio determination method for micro-EDM is presented. The pulse energy distribution ratio is a crucial parameter in the modeling of the EDM process. Instead of measuring the electrode temperature variation

Anode-Free Sodium Battery through in Situ Plating of Sodium Metal

, 2017
Sodium-ion batteries (SIBs) have been pursued as a more cost-effective and more sustainable alternative to lithium-ion batteries (LIBs), but these advantages come at the expense of energy density. In this work, we demonstrate that the challenge of energy

Study on ordered anode in proton exchange membrane water electrolysers

, 2023
Acidic oxygen evolution reaction is crucial for proton exchange membrane water electrolysers, which have been hindered by the high catalytic overpotential and high loading of noble metal catalysts and high mass transfer resistance.

Interfacial Modulation for High‐Efficiency Large‐Area Organic Photovoltaics and Perovskite‐Organic Tandem Solar Modules

Advanced Functional Materials, EarlyView.
Self‐assembled monolayers (SAMs) are promising hole‐transporting materials for organic photovoltaics (OPVs), but suffer from self‐aggregation and poor large‐area uniformity. We find that interfacial modification using nicotinic hydrazide can eliminate the residual SAM aggregates by forming energetically favorable complexes, yielding uniform SAM.

Investigating ionic liquids for optimizing lithium metal anode

, 2021
Developing renewable energy technology is an effective way to address the global warming and air pollution problems derived from depleting fossil fuels. Due to the high theoretical capacity (3860 mAh/g) and low electrochemical potential of lithium metal ...

Thermally Engineered Sodium‐Embedded Alumina with Programmable Synaptic Plasticity for Neuromorphic Transistors

Advanced Functional Materials, EarlyView.
A fully transparent, all‐metal‐oxide neuromorphic transistor using a sodium‐embedded alumina (SEA) electrolyte is demonstrated. By precisely tuning the thermal annealing process, the chemical composition of the SEA layer is controlled, allowing for the deterministic realization of both short‐term and long‐term synaptic plasticity within the same device

Electrochemical oxidation of carbon monoxide: from platinum single crystals to low temperature fuel catalysts. Part II: Electrooxidation of H2, CO and H2/CO mixtures on well characterized PtMo alloy [PDF]

Journal of the Serbian Chemical Society, 2003
The oxidation of hydrogen and hydrogen–carbon monoxide mixture has been investigated on well-characterized metallurgically prepared platinum–molybdenum (PtMo) alloys. It was concluded that the optimum surface concentration of molybdenum is near 23 mol.%.
