Summary: This study investigated the potential use of diffusive gradients in thin films to sample organic compounds (o-DGT) for wastewater-based epidemiology. Results showed that the HLB resin performed better than the XAD 18 and XDA-1 resins, with methamphetamine and heroin being the two most popular illicit drugs consumed among the studied populations. Overall, the findings demonstrate that o-DGT passive samplers are a promising tool for WBE studies.

Summary: Stormwater runoff contains metal contaminants that pose a potential risk to water quality. During a storm, the concentrations of dissolved and particulate metals increase. Most of the metals exist in a complexed form during the storm, posing a lower risk of toxicity to aquatic organisms. Current water quality guideline values may be too conservative when assessing stormwater pollution risks from metal contaminants.

Summary: This study presents a flexoelectric photodetector based on a thin-film heterostructure, demonstrating a giant strain gradient in LaFeO3 thin films grown on LaAlO3 substrates, leading to significant flexoelectric polarization and photovoltaic effect with nanosecond response time. This novel self-powered photodetector offers an alternative to traditional interface-type structures and opens up avenues for designing practical flexoelectric devices for nanoelectronics applications.

Summary: This study used diffusive gradients in thin films (DGT) to measure potentially bioavailable metals in coastal plain streams in the southeastern USA. The results showed that most metals were associated with particulates, colloids, or refractory organic complexes, while only a small portion existed in free ion or labile complex forms. The study also suggested that DGT exposure times longer than 5 days may lead to the accumulation of partly labile organic-metal complexes.

Summary: A new facile strategy was presented for the fabrication of anti-biofouling polyamide thin film composite membranes by incorporating benzalkonium chloride (BAC) during interfacial polymerization. The BAC-incorporated TFC membrane exhibited significantly enhanced reverse osmosis separation and anti-biofouling performance. Strong incorporation of BAC into PA led to the long-term durability of the membrane in terms of its separation and anti-biofouling performance.

Summary: This work analyzes the electrical stress effects caused by different voltages on a logic inverter device circuit based on TFT technology. It characterizes single IGZO TFTs and inverters with an active load configuration to investigate the behavior of their V-TH under various bias voltages. An analytical model is used to quantify the impact of electrical stress on the trapping parameters of the dielectric-semiconductor interface. The findings inform the determination of a maximum applied voltage bias and facilitate the estimation of circuit reliability and lifetime.

Summary: This study focused on grafting polyacrylamide onto polyamide thin-film composite reverse osmosis membranes via in-situ atomic transfer radical polymerization to improve biofouling resistance. The grafted membranes demonstrated enhanced anti-adhesion and bacteriostatic performance, leading to improved biofouling resistance. The greater water wettability of membrane surface and flexible chain structure of PAAm were proposed as factors contributing to the enhanced anti-adhesion and bacteriostasis towards bacteria.

Summary: Constructed wetlands can efficiently remove nitrogen from polluted agricultural run-off, but may produce nitrous oxide (N2O) emissions. This study showed seasonal variations in N2O fluxes in a off-stream CW treating nitrate-rich water, with a strong positive correlation to inlet NO3- concentrations and streamflow. Results indicate complete denitrification with only 9% of potential N2O formation emitted to the atmosphere.

Summary: Two polychrome sculptures from the late Middle Age were investigated using non-invasive techniques to characterize the applied brocade decoration. Portable instrumentation was used to perform X-ray powder diffraction and fluorescence measurements at the surface of the sculptures, leading to the identification of materials and differences between the artworks. The degradation of the decorations, as well as the identification of specific materials used in the gilding, were also assessed in the study.
