Summary: Computed tomography and conventional X-ray radiography often create micro-artifacts around metal implants, leading to false diagnoses of bone maturation or pathological peri-implantitis. A novel NIRF molecular imaging system was developed to repair these artifacts and monitor bone maturation. The system accurately identified image loss caused by metal artifacts and can be used to evaluate new types of implant fixtures or surface treatments.

Summary: Biothiols are small molecules with vital physiological functions, and their detection is mainly achieved by changing the fluorescence emission of fluorophores through the nucleophilic reaction ability of sulfhydryl groups. In recent years, many fluorescent probes recognizing biothiols based on the coordination ability of sulfhydryl groups and metals have been reported. The review of progress in this field is deemed timely and essential.

Summary: Biothiols, such as cysteine, homocysteine, and glutathione, play a crucial role in various biological processes, but abnormal levels can lead to serious diseases. Carbon-dots (CDs) have emerged as a promising tool for biothiols quantification due to their easy synthesis, nanosize, low toxicity, and real-time applicability. However, a comprehensive review on fluorescent CDs-based biothiols detection is lacking. This review provides valuable information on the assays, mechanisms, applications, selection of probes/CDs, sensory requirements, merits, limitations, and future prospects.

Summary: In this study, a gene-encoded fluorescence resonance energy transfer (FRET) fluorescent sensor for detecting dimethylation levels in living cells was designed and constructed. Its functional efficiency was evaluated both in vitro and in living cells, and it was verified that the sensor responded to changes in PRMT1 activity and different PRMT1-induced methylation levels. The optimized methyl sensor showed sensitivity to changes in methylation levels in living cells, making it a useful tool for real-time imaging of arginine methylation. This new tool has significant importance in posttranslational studies and may have wide applications.

Summary: Passive daytime radiative cooling (PDRC) technology, while promising for global spacing cooling, faces limitations in practical application due to reduced cooling effectiveness caused by wear and dirt contamination. Researchers have developed a renewable armor structure using fluorinated hollow glass microspheres to enhance the anti-fouling and cooling properties of PDRC coatings. The coatings exhibit high solar reflectance and thermal emittance, leading to significant temperature reduction below ambient temperature.

Summary: Methane chemistry is a significant area of research in catalysis. Converting methane into value-added chemicals is desirable but challenging due to its high C-H bonding energy and lack of pi bonding or unpaired electrons. Photocatalytic partial oxidation of methane to liquid oxygenates is a promising technology for achieving high efficiency and selectivity under mild conditions. The choice and activation of oxidants are crucial for its performance.
