DRIE Si Nanowire Arrays Supported Nano-Carbon Film for Deriving High Specific Energy Supercapacitors On-Chip
Lu, Pai; Chen, Xuyuan; Øhlckers, Per; Halvorsen, Einar; Hoffmann, Martin; Müller, Lutz (Peer reviewed; Journal article, 2021)Supercapacitor is a promising solution to storage of pulsed energy generated by MEMS energy harvesting systems, relying on its faster charging/discharging capability than secondary battery. To improve the energy density ... -
Enhancing Carbon Nanotube Growth in Large Scale Production: A Multifaceted Investigation of Key Factors in the CVD Process
Ibrahim, Abdelaziz Hassan Abdelghany (Master thesis, 2024)Electrification of transportation and personally owned vehicles has revitalized the need for enhanced power systems. Moreover, renewable energy systems' harvesting times and load peak times are sometimes incoherent. This ... -
Nano fabricated silicon nanorod array with titanium nitride coating for on-chip supercapacitors
Lu, Pai; Ohlckers, Per; Müller, Lutz; Leopold, Steffen; Hoffmann, Martin; Grigoras, Kestutis; Ahopelto, Jouni; Prunnila, Mika; Chen, Xuyuan (Journal article; Peer reviewed, 2016)We demonstrate high aspect ratio silicon nanorod arrays by cyclic deep reactive ion etching (DRIE) process as a scaffold to enhance the energy density of a Si-based supercapacitor. By unique atomic layer deposition (ALD) ... -
Nanoscale hetero-structured Co-Co(OH)2 composite/amorphous carbon core/shell bi-functional electrocatalysts electrochemically evolved from metastable hexagonal-phase cobalt for overall water splitting
Lu, Pai; Chen, Xuyuan (Peer reviewed; Journal article, 2021)Bi-functional electrocatalysts suited to alkaline water splitting systems are highly pursued, towards the most realistic application enabled by simplified electrolyzer design and cost-effective operation. Herein, a novel ... -
On-chip supercapacitor electrode based on polypyrrole deposited into nanoporous Au scaffold
Lu, Pai; Øhlckers, Per; Chen, Xuyuan (Journal article; Peer reviewed, 2016)On-chip supercapacitors hold the potential promise for serving as the energy storage units in integrated circuit system, due to their much higher energy density in comparison with conventional dielectric capacitors, high ... -
Performance of Co–Co(OH)2 coated nickel foam as catalysts for the hydrogen evolution reaction under industrially relevant conditions
Frederiksen, Morten Linding; Kragh-Schwarz, Marcus Viktor; Bentien, Anders; Nielsen, Lars Pleth; Lu, Pai (Peer reviewed; Journal article, 2023)In the present work, we employed a customised electrolyser test cell to quantify the electrocatalytic activity of a high-performing Co–Co(OH)2/nickel foam electrocatalyst, towards the hydrogen evolution reaction (HER) under ...
