Recycling red mud with raw coal to low-cost Fe/C/ceramic composite for efficient microwave absorption.
Environ Technol
June 2025
To solve the urgent issue of electromagnetic (EM) wave radiation pollution and promote the resource utilisation of red mud (RM, a solid waste), Fe/C/ceramic composite EM wave-absorbing materials were constructed by recycling RM with raw coal (RC) through simple mechanical mixing and then carbothermal reduction between FeO in RM and carbon component in RC. It was found that the calcined temperature of 900 °C can be considered the optimal formation temperature for Fe. In addition, a tuneable EM wave absorption performance could be attained by regulating the mass ratio of RC to RM (denoted as :).

- The "Blob" was a warm ocean anomaly that emerged in the Gulf of Alaska during the winter of 2013-2014, spreading across the northern North Pacific and affecting Oregon's coastal waters.
- It brought in at least 14 new copepod species not previously seen in the region, indicating a mix of offshore and subtropical origins for the warm waters.
- The prolonged warm conditions disrupted the local ecosystem, leading to significant changes in plankton communities and food web dynamics, with both increases in certain species and declines in key groups like copepods and euphausiids.
In spring/summer 2015, a toxic bloom by the diatom Pseudo-nitzschia (PN) occurred along the west coast of the United States which led to closures of the harvest of razor clams and Dungeness crabs. Twice monthly observations of temperature, salinity, nutrients, chlorophyll and phytoplankton species composition allowed us to track oceanographic conditions preceding and during the development of the bloom. PN cells were first detected during late winter 2015.
