  • Rapid detection of pesticide residues in fruits by surface

    In this work, surface-enhanced Raman scattering (SERS) spectrum was used to build a rapid analytical method for pesticide residues in fruits. QuEChERS (quick, easy, cheap, effective, rugged and safe) method was modified by multi-walled carbon nanotubes as clean-up sorbents. Overall recoveries of selected pesticide phosmet ranged from 77 to 97% in apples at three spiking levels (0.5, 1 and 2 mg

  • enervac Leak Detection electronic weighing device

    • Portable electronic leak detection. An electronic probe is used to detect and pinpoint leaking refrigerant as it escapes the system. These devices are typically small handheld units that emit and audible signal when refrigerant is detected. Good electronic detectors can typically detect leaks as small as 3 grams per year.

  • Microplastic ingestion ubiquitous in marine turtles

    Rising concerns regarding global impacts of microplastic pollution on marine wildlife mandates a reliable and comparable detection protocol (Nelms et al., 2016). Here, alongside investigation of macroplastic ingestion (5 mm), we develop a methodology to explore whether synthetic particles (<5 mm) could be isolated from marine turtle ingesta.

  • Soil organic matter, greenhouse gas emissions, and sorghum

    The addition of N in a nutrient‐deprived system can accelerate the decomposition of native organic matter, leading to a decrease in SOC and N (Chen et al., 2014; Qiu et al., 2016). The short‐term change in soil organic matter turnover caused by the addition of N to the nutrient‐deprived soils is called priming.
