A prototype of an optical sensor for the identification of diesel oil adulterated by kerosene
Kanyathare, Boniphace; Kuivalainen, Kalle; Räty, Jukka; Silfsten, Pertti; Bawuah, Prince; Peiponen, Kai-Erik (Springer Nature, 2018)Background Liquid fuel adulteration has several far-reaching impacts such as environmental pollution. A widespread practice is typically the adulteration of diesel oil by kerosene. The relatively cheap price of kerosene ...Tieteelliset aikakauslehtiartikkelit

Investigating elastic relaxation effects on the optical properties of functionalised calcium carbonate compacts using optics-based Heckel analysis
Bawuah, Prince; Karttunen, Anssi-Pekka; Markl, Daniel; Ridgway, Cathy; Korhonen, Ossi; Gane, Patrick; Zeitler, J Axel; Ketolainen, Jarkko; Peiponen, Kai-Erik (Elsevier BV, 2018)Heckel analysis is a widely used method for the characterisation of the compression behaviour of pharmaceutical samples during the preparation of solid dosage formulations. The present study introduces an optical version ...Tieteelliset aikakauslehtiartikkelit

Passive tunable and polarization-insensitive fan-like metamaterial absorber in the visible spectrum
Issah, Ibrahim; Li, Fangfang; Baah, Marian; Otoo, Isaac A.; Asilevi, Lewis; Bawuah, Prince; Asamoah, Benjamin O. (The Optical Society, 2021)We numerically study a fan-like metamaterial absorber (FMMA) composed of an Au-TiO2-Au multilayer with a 3-D finite-difference-time-domain method (FDTD) and verify it experimentally. Our proposed design shows high absorbance, ...Tieteelliset aikakauslehtiartikkelit

Plasmonic Implanted Nanogrooves for Optical Beaming
Daniel, Salman; Bawuah, Prince (Springer Nature, 2019)Surface plasmon polaritons are electromagnetic surface waves, which, due to their nanoscale nature, are efficiently used for modifying an output of optical field through a metallic nanoslit, e.g., extraordinary optical ...Tieteelliset aikakauslehtiartikkelit

Resolving the rapid water absorption of porous functionalised calcium carbonate powder compacts by terahertz pulsed imaging
Markl, Daniel; Wang, Parry; Ridgway, Cathy; Karttunen, Anssi-Pekka; Bawuah, Prince; Ketolainen, Jarkko; Gane, Patrick; Peiponen, Kai-Erik; Zeitler, J Axel (Elsevier BV, 2018)Cost effectiveness, ease of use and patient compliance make pharmaceutical tablets the most popular and widespread form to administer a drug to a patient. Tablets typically consist of an active pharmaceutical ingredient ...Tieteelliset aikakauslehtiartikkelit

Simultaneous Investigation of the Liquid Transport and Swelling Performance during Tablet Disintegration
Al-Sharabi, Mohammed; Markl, Daniel; Mudley, Theona; Bawuah, Prince; Karttunen, Anssi-Pekka; Ridgway, Cathy; Gane, Patrick; Ketolainen, Jarkko; Peiponen, Kai-Erik; Rades, Thomas; Zeitler, J. Axel (Elsevier BV, 2020)Fast disintegrating tablets have commonly been used for fast oral drug delivery to patients with swallowing difficulties. The different characteristics of the pore structure of such formulations influence the liquid transport ...Tieteelliset aikakauslehtiartikkelit
