Enhancing the Photocurrent of Top-Cell by Ellipsoidal Silver Nanoparticles: Towards Current-Matched GaInP/GaInAs/Ge Triple-Junction Solar Cells
No full textA way to increase the photocurrent of top-cell is crucial for current-matched and highly-efficient GaInP/GaInAs/Ge triple-junction solar cells. Herein, we demonstrate that ellipsoidal silver nanoparticles (Ag NPs) with better extinction performance and lower fabrication temperature can enhance the light harvest of GaInP/GaInAs/Ge solar cells compared with that of spherical Ag NPs. In this method, appropriate thermal treatment parameters for Ag NPs without inducing the dopant diffusion of the tunnel-junction plays a decisive role. Our experimental and theoretical results confirm the ellipsoidal Ag NPs annealed at 350 °C show a better extinction performance than the spherical Ag NPs annealed at 400 °C. The photovoltaic conversion efficiency of the device with ellipsoidal Ag NPs reaches 31.02%, with a nearly 5% relative improvement in comparison with the device without Ag NPs (29.54%). This function of plasmonic NPs has the potential to solve the conflict of sufficient light absorption and efficient carrier collection in GaInP top-cell devices

A self-regenerating Pt/Ge-MFI zeolite for propane dehydrogenation with high endurance
No full text: Supported noble metal cluster catalysts are typically operated under severe conditions involving switches between reducing and oxidizing atmospheres, causing irreversible transformation of catalyst structure and thereby leading to permanent deactivation. We discovered that various Pt precursors spontaneously disperse in Ge-MFI zeolite, which opposes the Ostwald ripening phenomenon, producing self-regenerating Pt/Ge-MFI catalysts for propane dehydrogenation. These catalysts reversibly switch between Pt clusters and Pt single-atoms in response to reducing reaction and oxidizing regeneration conditions. This environmental adaptability allows them to completely self-regenerate over 110 reaction-regeneration cycles in propane dehydrogenation. They exhibited unprecedented sintering-resistance when exposed to air at 800 °C for 10 days. Such spontaneous metal dispersion in Ge-zeolites is a robust and versatile methodology for fabricating various Rh, Ru, Ir and Pd cluster catalysts

Publisher Copyright: © 2014 IEEE.Imprecise vowel articulation can be observed in people with Parkinson's disease (PD). Acoustic features measuring vowel articulation have been demonstrated to be effective indicators of PD in its assessment. Standard clinical vowel articulation features of vowel working space area (VSA), vowel articulation index (VAI) and formants centralization ratio (FCR), are derived the first two formants of the three corner vowels /a/, /i/ and /u/. Conventionally, manual annotation of the corner vowels from speech data is required before measuring vowel articulation. This process is time-consuming. The present work aims to reduce human effort in clinical analysis of PD speech by proposing an automatic pipeline for vowel articulation assessment. The method is based on automatic corner vowel detection using a language universal phoneme recognizer, followed by statistical analysis of the formant data. The approach removes the restrictions of prior knowledge of speaking content and the language in question. Experimental results on a Finnish PD speech corpus demonstrate the efficacy and reliability of the proposed automatic method in deriving VAI, VSA, FCR and F2i/F2u (the second formant ratio for vowels /i/ and /u/). The automatically computed parameters are shown to be highly correlated with features computed with manual annotations of corner vowels. In addition, automatically and manually computed vowel articulation features have comparable correlations with experts' ratings on speech intelligibility, voice impairment and overall severity of communication disorder. Language-independence of the proposed approach is further validated on a Spanish PD database, PC-GITA, as well as on TORGO corpus of English dysarthric speech.Peer reviewe
Investigation of older people's needs at home to inspire inclusive home design with smart products and services
No full textAs the world population is ageing, many researchers have explored and contributed to improving older people's quality of life from diverse perspectives. The living room has been identified as one of the most frequently used spaces at home. It is multi-functional: used for reading, tea/coffee, TV and entertainment, meeting with friends, meals, and even sleeping. This project aims to investigate the experiences of older people with their living room at home to identify risks and challenges they face in their day-to-day life and indicate the reasons behind it. An 9-week ethnographic user study approach was employed to explore older people's natural behavior with multiple activities in their living room through video-based observation, in-depth interview, and cultural probes with 11 households. Qualitative content analysis was applied to analyze the collected data to identify key factors that have an impact on older people's living experience in their living room. Finally, all findings from this project help the author to develop design insights for improving living room space design, furniture and furniture arrangement, and atmospheres design to improve older people's standard of living in the UK
