LITES-Based Sensitive CO2 Detection Using 2 μm Diode Laser and Self-Designed 9.5 kHz Quartz Tuning Fork

Sensors, Год журнала: 2025, Номер 25(7), С. 2099 - 2099

Опубликована: Март 27, 2025

A carbon dioxide (CO2) sensor based on light-induced thermoelastic spectroscopy (LITES) using a 2 μm diode laser and self-designed low-frequency trapezoidal-head QTF is reported for the first time in this invited paper. The with low resonant frequency of 9464.18 Hz high quality factor (Q) 12,133.56 can significantly increase accumulation signal level CO2-LITES sensor. continuous-wave (CW) distributed-feedback (DFB) used as light source, strongest absorption line CO2 located at 2004.01 nm chosen. comparison between standard commercial 32.768 kHz performed. experimental results show that has an excellent linear response to concentration, its minimum detection limit (MDL) reach 46.08 ppm (parts per million). When average increased 100 s Allan variance analysis, MDL be improved 3.59 ppm. Compared 16.85 QTF, performance by 4.7 times, demonstrating superiority QTF.

Temperature extremes nip invasive macrophyte Cabomba caroliniana A. Gray in the bud: potential geographic distributions and risk assessment based on future climate change and anthropogenic influences

Frontiers in Plant Science, Год журнала: 2024, Номер 15

Cabomba caroliniana A. Gray, an ornamental submerged plant indigenous to tropical America, has been introduced numerous countries in Europe, Asia, and Oceania, impacting native aquatic ecosystems. Given this species is a popular aquarium widely traded, there high risk of introduction invasion into other environments. In the current study potential global geographic distribution C. was predicted under effects climate change human influence optimised MaxEnt model. The model used rigorously screened occurrence records from hydro informatic datasets 20 associated influencing factors. findings indicate that temperature human-mediated activities significantly influenced . At present, covers area approximately 1531×10 4 km 2 appropriate habitat, especially south-eastern parts South, central North Southeast eastern Australia, most Europe. suitable regions are anticipated expand future scenarios; however, dynamics changes vary between different extents change. For example, expected higher latitudes, following increases SSP1–2.6 SSP2–4.5 scenarios, intolerance extremes may mediate at latitudes extreme e.g., SSP5–8.5. Owing severe impacts its causes, early warning stringent border quarantine processes required guard against hotspots such as, Peru, Italy, South Korea.
