Complex electrolyte diffusion through the stacked graphene nanosheets limits their electrochemical performance. As a potential solution, this study explored of nitrogen-doped quantum dots (NGQDs) to induce 3D porous orientation holey oxide (hGO) nanosheets. The sizes NGQDs and antisolvent for phase separation assisted assembly were optimized achieve nanoporous network. This nano-network serves ...

The discovery of oxygen and carbon monoxide tolerant [NiFe] hydrogenases was the first necessary step toward the definition of a novel generation of hydrogen fed biofuel cells. The next important milestone is now to identify and overcome bottlenecks limiting the current densities, hence the power densities. In the present work we report for the first time a comprehensive study of herringbone ca...

The thermal conductivity represents a key parameter for the consideration of temperature control and inhomogeneities in batteries. A high‐effective will entail lower gradients thus more homogeneous distribution, which is considered beneficial longer lifetime battery cells. Herein, impact microstructure within porous electrode coating obtained by different compression rates its contact to curren...

Organic solar cells have great potential for upscaling due to roll-to-roll processing and a low energy payback time, making them an attractive sustainable energy source for the future. Active layers coated with water-dispersible Landfester particles enable greater control of the layer formation and easier access to the printing industry, which has reduced the use of organic solvents since the 1...

AuFe electrodeposits onto a rotating disk electrode were examined to assess the composition and current efficiency behavior when citric acid, ascorbic acid, or a combination of both is present in the electrolyte. Nanowires were subsequently fabricated with pulsed current deposition to create compositionally, multilayered Au/FeAu nanowires. The FeAu layer of the nanowires was porous in a citrate...

The precipitation of particles in an electrostatic precipitator (ESP) results in striking dust patterns at the collecting electrodes, strongly depending on forces of the electrohydrodynamic (EHD) field in the duct. Due to precipitator geometry, electrical operation status, and process parameters, areas of high and low dust density are visible. Since latest results show a direct correlation of p...

This work describes the application of the electrical resistivity (ER) method to delineating subsurface structures and cavities in Kuala Lumpur Limestone within the Batu Cave area of Selangor Darul Ehsan, Malaysia. In all, 17 ER profiles were measured by using a Wenner electrode configuration with 2 m spacing. The field survey was accompanied by laboratory work, which involves taking resistivit...

a r t i c l e i n f o Microelectrodes on solid electrolytes, contacted by current-collecting tips, have become increasingly important for analyzing electrochemical properties of electrode materials in solid state ionics. Samples are usually asymmetrically heated from the bottom side. It is shown experimentally, e.g. by thermovoltage measurements, impedance spectroscopy and infrared camera pictu...
