Research progress on gas stripping for highly-concentrated ammonia-nitrogen wastewater treatment

open access: yesGongye shui chuli
Highly-concentrated ammonia-nitrogen(NH3-N) wastewater has caused serious pollution to environment with its massive discharges and high toxicity. The gas stripping method has the advantages of high removal efficiency, simple operation, and resource ...

Gasotransmitters in Modern Medicine: Promises and Challenges in the Use of Porous Crystalline Carriers

open access: yesAdvanced Healthcare Materials, EarlyView.
This perspective provides an overview of the growing interest in utilizing various gasotransmitters—small gaseous signaling molecules namely nitric oxide (NO), carbon monoxide (CO), and hydrogen sulfide (H2S)—for several therapeutic applications, with emphasis on the potential use of porous materials as carriers to provide safe and controlled local ...

Migration and pollution [PDF]

open access: yes, 2003
We explore the links between migration of labour and location specific (urban) pollution, suggesting a sense in which pollution can be welfare improving. In a conventional Harris-Todaro model of urban-rural migration, individuals migrate so as to equate the expected urban wage (given a downward rigid real wage in the urban sector) to the real wage ...

Systematic Comparison of Commercial Uranyl‐Alternative Stains for Negative‐ and Positive‐Staining Transmission Electron Microscopy of Organic Specimens

open access: yesAdvanced Healthcare Materials, EarlyView.
Negative‐ and positive‐staining TEM is essential for rapid nanometer‐resolution characterization of organic specimens ranging from nanoparticles to cells. Uranyl salts are widely used negative‐/positive‐stains but are radioactive and highly toxic to users and the environment.

The Effects of Anthropogenic Air and Light Pollution on Astrophysics and Society [PDF]

open access: yesarXiv
Light and air pollution are the two main forms of pollution, containing the highest concentration in urban areas. I set out to investigate the effects of anthropogenic air and light pollution on the night sky, how this affects the astronomical data-collecting process, and how the general public perceives both forms of pollution.

Designing for Degradation: Transient Devices Enabled by (Nano)Cellulose

open access: yesAdvanced Materials, EarlyView.
Recent progress in transient devices enabled by (nano)cellulosic materials is reviewed. Transiency mechanisms, advantages of nanocelluloses, and a suite of applications are discussed. A circular thinking approach coupled with life cycle assessment is applied to critically revisit the potential, advantages, and challenges of nanocellulose‐enabled ...
