Low-Energy Femtosecond Laser Lens Fragmentation Techniques for Cataract.

Femtosecond laser has become an important tool in cataract surgery due to its precision and minimally invasive nature. However, the strong scattering properties of the lens limit surgical efficiency, especially when it comes to effectively cutting highly opaque and hard cataracts with femtosecond laser. This study proposes a method for achieving optical transparency in opaque lenses through tartrazine treatment.

Chlorine-functionalized black phosphorus quantum dots induced superoxide anion generation and depletion for efficient chemiluminescence detection.

Background: Due to their unique optoelectronic properties, environmental friendliness, and excellent biocompatibility, metal-free quantum dots have been a new star in exploring novel chemiluminescence (CL) systems for analytical applications in recent years. However, unknown CL property, relatively weak emission and instability of some of them in water (eg. black phosphorus) often seriously hindered their further applications.

Accelerated photonic design of coolhouse film for photosynthesis via machine learning.

Controlling the suitable light, temperature, and water is essential for plant photosynthesis. While greenhouses/warm-houses are effective in cold or dry climates by creating warm, humid environments, a cool-house that provides a cool local environment with minimal energy and water consumption is highly desirable but has yet to be realized in hot, water-scarce regions. Here, using a synergistic genetic algorithm and machine learning, we propose and demonstrate a coolhouse film that regulates temperature and water for photosynthesis without requiring additional energy or water.

Amino-rich silicon quantum dots as efficient activator with intrinsic chemiluminescence for the detection of peroxydisulfate.

The specific detection of peroxydisulfate (SO, PDS) is significant and challenging due to the rapid development of PDS-related technologies and their widespread application in multiple fields. However, traditional analytical methods are mainly based on their strong oxidizing properties, making it difficult to simultaneously achieve specific identification and high sensitivity for PDS detection in complex water environments. Here, we purposely prepared amino-rich SiQDs (N-SiQDs) as an effective catalyst and introduced HO acts as a co-reactant for PDS activation and determination with strong intrinsic chemiluminescence (CL) emission.

Modulated oxygen vacancies in europia clusters/black phosphorus induced signal amplification for efficient chemiluminescence sensing.

In this work, we proposed an oxygen vacancy engineering strategy to boost the chemiluminescence (CL) efficiency in europia clusters/black phosphorus quantum dots (EuO/BPQDs), which could dramatically amplify the ClO CL emission through electron transfer. Accordingly, a sensitive and direct CL sensing platform for hypochlorite and titanium ions was constructed. This work provides a neoteric methodology by modulating the surface state of nanoparticles to boost the CL sensitivity.
