Water Reuse—Retrospective Study on Sustainable Future Prospects
Published on 2025-03-10 by Morteza Abbaszadegan, Absar Alum, Masaaki Kitajima, Takahiro Fujioka, Yasuhiro Matsui, Daisuke Sano, Hiroyuki Katayama @MDPI
Abstract: In recent decades, societies and economies across the globe have started to show signs of stress associated with water shortages. Meeting the sustainability benchmarks in arid and semi-arid regions has caused water reuse to be considered a viable alternate source to augment the existing water supply resources. Water reuse, resource recovery, and recycling are extensions of the concept of a circular economy that has been practiced in other fields. Globally, the U.S. has played a leadership role i[...]
Our summary: Retrospective study on global water reuse regulations and technological advancements, focusing on challenges of viral pathogens and perfluorinated compounds, and the role of public-private partnerships in ensuring water sustainability.

Degradation and Ecotoxicity Mitigation of Perfluorooctane Sulfonate by Aeration-Assisted Cold Plasma
Published on 2025-03-08 by Sengbin Oh, Joo-Youn Nam, Youngpyo Hong, Tae-Hun Lee, Jae-Cheol Lee, Hyun-Woo Kim @MDPI
Abstract: Various advanced oxidation processes have been used to degrade perfluorooctane sulfonate (PFOS), one of the persistent organic pollutants that dissolves in aquatic ecosystems, but these processes suffer from inherent limitations. This study proposes aeration-assisted cold plasma (CP) technology as an alternative. PFOS removal via CP treatment reached 62.5% after 1 h of exposure, with a degradation rate constant of 3.1 h−1. The detection of sulfate (SO42−) in the solut[...]
Our summary: Advanced oxidation processes have limitations in degrading PFOS in aquatic ecosystems. Aeration-assisted cold plasma technology shows promise in achieving 62.5% PFOS removal after 1 hour, with evidence of effective degradation through sulfate detection. Acute toxicity may initially increase but can be mitigated with additional exposure to reactive species from CP.

Recent Advances in Triboelectric Nanogenerators for Sports Applications
Published on 2025-03-07 by M�nica P. S. Ferreira, In�s Ferreira, V�nia Pais, Liliana Leite, Jo�o Bessa, Fernando Cunha, Ra�l Fangueiro @MDPI
Abstract: Triboelectric nanogenerators (TENGs) can convert the mechanical energy of physical activities into electricity. This is particularly useful in sports applications, where physical activity can power devices such as wearables that can provide real-time feedback on athletes’ performance or health. To work, a TENG usually needs tribopositive and tribonegative materials. Currently, the vast majority of TENGs use materials containing perfluoroalkyl and polyfluoroalkyl substances (PFAS) a[...]

KOH-Assisted Chemical Activation of Camelina Meal (Wild Flax) to Treat PFOA-Contaminated Wastewater
Published on 2025-03-03 by Shivangi Jha, Falguni Pattnaik, Oscar Zapata, Bishnu Acharya, Ajay K. Dalai @MDPI
Abstract: This study is constituted of the chemical activation of camelina meal (CM) biochar and the utilization of these activated carbon for the adsorption of perfluorooctanoic acid (PFOA) from water. Camelina meal, a sustainable agro-based byproduct, underwent slow pyrolysis and subsequent chemical activation with potassium carbonate (K2CO3), potassium hydroxide (KOH), and sodium hydroxide (NaOH). Among these chemical activating agents, KOH emerged as the one of most efficient activating agents, yieldi[...]
