Objectives: The management of elderly-onset rheumatoid arthritis (EORA) is challenging due to progressive functional disability, increased comorbidities, and high drug-related risks. EORA is defined as disease onset after 60 years since 1985. We assessed whether this cut-off age was optimal in a progressively ageing society.
View Article and Find Full Text PDFIron pyrite [cubic FeS (cFeS)] is considered as an earth-abundant and low-cost thin-film photovoltaic material. However, the conversion efficiency of cFeS-based solar cells remains below 3%. To elucidate this limitation, we evaluate the optical and electrical characteristics of cFeS single crystals that are grown using the flux method, thus providing us an understanding of the electron transport behavior of cFeS single crystals.
