A lanmodulin-based fluorescent assay for the rapid and sensitive detection of rare earth elements.

Sensitive and rapid detection methods for rare earth elements (REEs), including lanthanides (Lns), will facilitate the mining and recovery of these elements. Here, we innovated a rapid, highly selective and sensitive fluorescence detection method for Lns, based on Hans-Lanmodulin, a newly discovered protein with high selectivity and binding affinity for rare earth elements. By labelling the fluorescein moiety FITC onto Hans-Lanmodulin, named as FITC-Hans-LanM.

Can a brief guided nature walk reduce distress and improve resilience, mindful attention, and sleep quality? Evidence from a pilot study with two-week follow-up.

Despite trends of deteriorating mental health globally, help-seeking remains suboptimal. Identifying less stigmatising, low-cost, and scalable approaches to mental health care is critical. We investigated the acceptability and psychological benefits of a 30-minute guided nature walk programme in an accessible country park in Hong Kong among 100 community members.

Repeated axial compressive performance of GCFST columns: Test investigation and numerical analysis.

Geopolymer concrete (GC) is green and environmentally friendly. In order to comprehensively study the mechanical properties and influence mechanism of geopolymer concrete-filled steel tubular (GCFST) columns under various working conditions, this study takes the strength grade of geopolymer concrete, length-diameter ratio and wall thickness of steel tube as design parameters. Eight GCFST columns are designed and the compressive performances are conducted under repeated axial compression.

Low-Intensity Online Intervention for Mental Distress Among Help-Seeking Young People in Hong Kong: A Randomized Clinical Trial.

Importance: Mental health issues among young people are increasingly concerning. Conventional psychological interventions face challenges, including limited staffing, time commitment, and low completion rates.

Objective: To evaluate the effect of a low-intensity online intervention on young people in Hong Kong experiencing moderate or greater mental distress.

A photo-thermal dual crosslinked chitosan-based hydrogel membrane for guided bone regeneration.

Alveolar bone defects caused by inflammation or trauma jeopardize patients' oral functions. Guided bone regeneration (GBR) is widely used in repairing periodontal tissue, with barrier membranes play a crucial role in preserving the bone regeneration space. In this study, an injectable dual-crosslinked hydrogel was developed to improve the existing barrier membranes in flexibility and functionality.
