Summary: In this study, snail shells calcined at different temperatures were analyzed using various characterization techniques. The main objective was to identify different forms of calcium carbonate and calcium hydroxide in the shells. The obtained calcium hydroxide played a crucial role in the synthesis of the hydroxyapatite/L-lysine composite. By using the composite to chemically modify an electrode, it was found that electronic transfer was facilitated and the modified electrode exhibited positive charge in strongly acidic medium, showing good affinity with a certain substance. Furthermore, the composite showed excellent sensor performance in toluidine blue electroanalysis.

Summary: This study investigates the environmental significance of the oxygen isotopic composition of land snail shells in Alaska and Scandinavia. The results show that shell delta O-18 values can track precipitation delta O-18 values. Shell delta O-18 values also differ significantly among sympatric species, and species-level isotopic variations should be considered at the local and microhabitat scale.

Summary: The application of Δ47 in land snails as a temperature proxy is relatively rare compared to other carbonate materials. This study cultured two species of land snails under controlled temperature conditions and found a significant negative correlation between shell Δ47 values and culturing temperature within their respective optimum temperature ranges. However, shell Δ47 values at lower temperatures showed a negative deviation, which may be attributed to a vital effect associated with CO2 degassing during carbonate precipitation.

Summary: Environmental noise is a major noise pollution that seriously affects human physical and mental health. Traditional commercial fiber sound-absorption materials have limitations in absorbing low-frequency waves and being fire-resistant, which restricts their wide application. To solve these problems, a novel strategy combining flexible nanofibers and rGO/MXene nanosheets was proposed to fabricate rGO/MXene/SiO2 nanofibers composite aerogel with hierarchically porous structure. The obtained composite aerogel has an extremely low density and superior low-frequency sound absorption ability, and it can deform up to 80% and quickly recover. Moreover, it can be easily produced on a large scale, providing a reference for the development of new generation of sound-absorbing products.

Summary: A novel flexible SiO2 aerogel composite nanofiber membrane with a strawberry-like structure and excellent thermal insulation properties was prepared by electrospinning technology. The addition of nano-pore structure SiO2 aerogel particles resulted in a discontinuous heat transfer path, giving the membrane an ultra-low thermal conductivity and large surface area. The membrane also showed great fire resistance, high-temperature stability, and temperature-invariant flexibility, making it promising for insulation and gas adsorption applications. The successful preparation of this flexible nanofiber membrane opens up a new pathway for designing materials with excellent thermal insulation and adsorption properties.

Summary: From robotic applications to autonomous driving, environment modeling plays a crucial role in connecting perception and decision layers. Space-oriented models are used in robotic applications to accurately represent space occupation. However, with the development of autonomous driving, the reliability of element-oriented models is affected by missed detection and irregular objects. To address this issue, a new view of driving environment called USEB is proposed, which improves reliability by merging space occupation and expressing semantics and dynamics.

Summary: In recent years, the development of 2D nonlayered Bi2O2Se-based electronics and optoelectronics has attracted great attention due to their high electron mobility, stability, and narrow band gaps. However, conventional Bi2O2Se-based photodetectors suffer from issues such as high dark current, slow response speed, and persistent photoconductivity effect, limiting their applications in fast-response imaging sensors and low-power broadband detection. In this study, a Bi2O2Se/2H-MoTe2 van der Waals heterostructure is reported, which shows improved performance in terms of responsivity, detectivity, and conversion efficiency. The proposed heterostructure is considered a promising candidate for integrated circuits, image sensors, and low-power detection.

Summary: In this study, the effects of QU-loaded liposomes on macrophage-mediated lung inflammation were investigated. The results showed that liposomal QU inhibited lung inflammation and had no obvious toxicity on vital organs in septic mice. Mechanistically, the anti-inflammatory effects of liposomal QU were associated with inhibition of NF-κB-dependent cytokine production and inflammasome activation in macrophages.

Summary: Ventilator-induced lung injury (VILI) is characterized by airway inflammation in mechanically ventilated patients. Excessive mechanical loading, such as high stretch on airway smooth muscle cells (ASMCs), may be a major cause of VILI. This study found that high stretch mainly induced endoplasmic reticulum (ER) stress and activated ER stress-related signaling and downstream inflammation response in ASMCs.

Summary: Blindness often occurs due to corneal abnormalities, and corneal transplantation is the most effective treatment method. Developing high-quality artificial corneas is crucial since there is a shortage of available donor corneas for transplantation. Collagen, the main component of natural cornea, is commonly used as a material in corneal repair. However, promoting the regeneration of corneal nerves after surgery remains a challenge. In this study, researchers developed a novel collagen-based material that showed promising results in promoting the growth of nerve cells and corneal epithelial cells. The findings suggest that this material may have potential applications in cornea tissue engineering.
