Photocatalytic nitrogen fixation can make ammonia from nitrogen and water under mild conditions, but slow nitrogen delivery and product build-up limit output. Now, a floating solar interface couples nitrogen reduction with evaporation, greatly speeding up ammonia formation and concentrating a high-purity product in the condensate.

ABSTRACT Since Beames and Brown’s initial study in 2005, ‘Outdoor Education in Hong Kong: Past, Present, and Future’, outdoor education in Hong Kong has continued to evolve. Two decades later, factors such as social media, periods of social unrest and the COVID-19 pandemic have profoundly influenced the culture of Hong Kong and, consequently, outdoor education. This study employed an exploratory mixed methods approach to evaluate and compare the industry’s transformation since the original paper.

Abstract Scalp cooling therapy (SCT) improves chemotherapy-induced alopecia (CIA), but there are few published data about its efficacy in an Asian-predominant population. We report our tertiary institution experience of SCT in patients with breast or gynaecological cancers undergoing chemotherapy. The Paxman scalp cooling system was employed for eligible women with breast or gynaecological cancers receiving anthracycline or taxane-based chemotherapy.
