• Recycling of aluminium laminated pouches and Tetra Pak cartons by molten metal pyrolysis - Pilot-scale experiments and economic analysis 

  Riedewald, Frank; Wilson, Edward; Patel, Yunus; Vogt, Daniel; Povey, Ian; Barton, Killian; Lewis, Liam; Caris, Tom; Santos, Silvia; O'Mahoney, Maria; Sousa-Gallagher, Maria J. (Elsevier Ltd., 2021-12-09)

  Aluminium laminated (AL) pouch packages and aluminium laminated Tetra-Pak cartons are considered unrecyclable, reducing their otherwise excellent lifecycle performance. This paper describes experimental results on pilot ...
• Spurious suppression techniques for 3-D printed coaxial resonator bandpass filters 

  Zhao, Kunchen; Psychogiou, Dimitra (Institute of Electrical and Electronics Engineers (IEEE), 2021-09-22)

  Design methods to enhance the passband-to-stopband bandwidth of coaxial bandpass filters (BPFs) are reported. Stopband enhancement is achieved by: 1) introducing a transmission zero (TZ) through mixed electromagnetic (EM) ...
• A review of self-seeded germanium nanowires: synthesis, growth mechanisms and potential applications 

  Garcia-Gil, Adriàl; Biswas, Subhajit; Holmes, Justin D. (MDPI, 2021-08-04)

  Ge nanowires are playing a big role in the development of new functional microelectronic modules, such as gate-all-around field-effect transistor devices, on-chip lasers and photodetectors. The widely used three-phase ...
• Can sustainable, monodisperse, spherical silica be produced from biomolecules? A review 

  Curley, Ricky; Holmes, Justin D.; Flynn, Eoin J. (Springer, 2021-05-25)

  Spherical silica is a fundamentally important material with uses across a wide and diverse range of areas. However, the synthetic routes to producing spherical silica—typically Stöber processes—are inherently unsustainable ...
• Probing lattice dynamics in ST12 phase germanium nanowires by Raman spectroscopy 

  Raha, Sreyan; Srivastava, Divya; Biswas, Subhajit; Garcia-Gil, Adrià; Karttunen, Antii J.; Holmes, Justin D.; Singha, Achintya (AIP Publishing, 2021-12-08)

  Germanium (Ge) plays a crucial role in setting up important functionalities for silicon-compatible photonics. Diamond cubic germanium is an extensively studied semiconductor, although its other exotic forms, like BC8, ST8, ...
