Controlled patterning of metallic nanogaps and nanogap arrays via adhesion lithography
Luo, Sihai (Doctoral theses at NTNU;2021:181, Doctoral thesis, 2021)Existing nanofabrication methods typically rely on techniques such as optical lithography, electron-beam lithography or focused ion beam milling that enable high fidelity patterning but suffer from various limitations in ... -
Detection of environmental nanoplastics via surface-enhanced Raman spectroscopy using high-density, ring-shaped nanogap arrays
Luo, Sihai; Zhang, Junjie; de Mello, John Christian (Peer reviewed; Journal article, 2023)Micro- and nano-plastics (MNPs) are global contaminants of growing concern to the ecosystem and human health. In-the-field detection and identification of environmental micro- and nano-plastics (e-MNPs) is critical for ... -
Flexible Transparent Electrodes Formed from Template-Patterned Thin-Film Silver
Luo, Sihai; Lian, Enkui; He, Jiali; de Mello, John Christian (Peer reviewed; Journal article, 2023)Template-patterned, flexible transparent electrodes (TEs) formed from an ultrathin silver film on top of a commercial optical adhesive – Norland Optical Adhesive 63 (NOA63) – are reported. NOA63 is shown to be an effective ... -
OLIA: An open-source digital lock-in amplifier
de Mello, John Christian; Harvie, Andrew J. (Peer reviewed; Journal article, 2023)The Open Lock-In Amplifier (OLIA) is a microcontroller-based digital lock-in amplifier built from a small number of inexpensive and easily sourced electronic components. Despite its small credit card-sized form-factor and ...
