As a result, this review provides the following relevant new insights and perspectives beyond those available in previously published reviews. It is definitively estimated that currently ~ 53 Mt/year dry sewage sludge is produced globally by wastewater treatment plants. This would increase to ~ ...
The current paper reviews selected key studies and provides information on the current status and applications of hydrogen for reduction of metal oxides (with a focus on reduction kinetics and mechanisms of non-ferrous oxides). This study summarized that hydrogen has the potential to be used to ...

These reviews are deep dives and long enough to prevent me from babbling on here, so lets get to it!Iron Maiden – Senjutsu:Here we go, Maiden’s seventeenth studio album Senjutsu, which is actually only the second time I’ve gotten to write about a new record of theirs in the near ...
The substrate is maintained at 600 °C during the 2 hours of deposition and the subsequent heat treatments. In a second step, an hour long annealing was performed at 600 °C right after the deposition under oxygen par- tial pressure of 1 × 10−2 mbar. The sample ...
(Brandão et al.,2017) but are only applicable to parts with accessible surfaces; heat treatment can relieve internal stresses and improve ductility (Gibson et al.,2014; Girelli et al.,2019); and hot isostatic pressing (HIP) can close cracks and pores in many instances (du Plessis & Mac...
emphasizing the urgent need for treatment. Traditional remediation techniques for heavy metal contamination include physical, chemical, and biological methods. Each of these methods has its advantages and disadvantages and can be combined to remove (transform) or reduce heavy metals in contaminated soils...
