A comprehensive review on the progress of Layered Double Hydroxides (LDHs) in environmental applications, focusing on their synthesis, functionalization, and applications in adsorption, catalysis, and photoreduction. This article explores the mechanisms of pollutant removal and the potential of LDH-based composites for wastewater treatment, offering insights into future research directions.

In my final PhD paper (with Gabriel Sigmund, Thilo Hofmann, Naresh Kumar, Thorsten Hüffer and Andreas Mautner) we experimentally deep-dive into the role of solution chemistry in metal/metalloid sorption by carbonaceous sorbents. Have a first look at this OA publication in RSC journal Environmental Science: Water Research & Technology. https://lnkd.in/eS8vSh7K We hope more studies account for these matrices that contain ubiquitously found organic matter and iron particulate phases and dissolved ions such as phosphates and calcium. The need to work with such matrices when we talk about sorption was pointed out 5 years ago by David Sedlak in his editorial comment "Sifting through the embers" in ES&T.

Using wastewater to make products with added value helps recycle water and eases the strain on freshwater resources.  Kudos to you, Mr. Shobharajsinh Rathod, for the  most recent publication in the journal Surfaces and Interfaces (https://lnkd.in/dd35Zj5h), "Synergistic RB5 Dye Degradation and Oxygen Evolution Reaction (OER) Catalysis by WO3 Nano-Pellets: Mechanistic Insights and water remediation Applications" (IF=6.2,Q1) from our group. Putting these techniques into practice can make a big difference in reaching a number of sustainable development goals.

I am excited to share that our latest book chapter has been published in 'Biochar for Environmental Management'. This chapter aims to describe the connection between feedstock composition, carbonization conditions, and biochar structure at the micro- and nano-level scale. The link between these structures and adsorption, reaction, and electrochemical phenomena relevant to the use of biochar for environmental remediation are discussed.

The global commercialisation of companies and technologies in the bioeconomy, using engineering and synthetic biology, are seeing rapid growth and advancement. However, the lack of related technical standards and metrics will likely cause major challenges. Hear from Professor Paul Freemont from Imperial College London on their report, drafted in collaboration with international stakeholders from academia, industry, and government, lays the groundwork for establishing open, voluntary standards for engineering biology. Paul is speaking on Day Two - check out the full agenda here: https://bit.ly/3yKoAPj #WBM24 #WorldBioMarkets #ImperialCollege #Bioeconomy #Biomanufacturing #IndustrialBiomanufacturing #EngineeringBiology #SynBio

🌊 In the spirit of World Ocean Day, we are committed to contributing to cleaner (ocean) water by removing microcontaminants through electrochemistry. Sara Feijoo Moreira shares insights from her PhD research at the Department of Chemical Engineering - Campus De Nayer, under the guidance of Prof. Raf Dewil. Treating wastewater: how to remove microcontaminants? Have you ever seen wastewater from a factory? This usually looks very clean, thanks to wastewater treatment. Yet it may still contain many traces of drugs, pesticides, or cleaning agents. These so-called microcontaminants end up in rivers and cause damage to the environment. In the lab, Sara Feijoo Moreira and her colleagues developed a method that uses electrochemistry to remove these micropollutants from wastewater. #WorldOceanDay #CleanOceans #Electrochemistry #SustainableFuture    https://lnkd.in/e85ccHWX..

"Current methods to destroy PFASs require extreme heat or pressure, and they work safely only on filtered-out waste. Researchers have long wondered whether bacteria could break down the chemicals in natural environments, providing a cheaper and more scalable approach. But carbon-­fluorine bonds occur mainly in humanmade materials, and PFASs have not existed long enough for bacteria to have specifically evolved the ability to digest them. The new study—though not the first to identify a microbe that destroys carbon-fluorine bonds—provides a step forward, says William Dichtel, a chemist at Northwestern University who studies energy-efficient ways to chemically degrade PFASs. To identify a promising set of bacteria, the study’s authors screened several microbe communities living in wastewater. Four strains from the Acetobacterium genus stood out, the team reported in Science Advances. Each strain produced an enzyme that can digest caffeate—a naturally occurring plant compound that roughly resembles some PFASs. This enzyme replaced certain fluorine atoms in the PFASs with hydrogen atoms; then a “transporter protein” ferried the fluoride ion by-products out of the single-celled microbes, protecting them from damage. Over three weeks most of the strains split the targeted PFAS molecules into smaller fragments that could be degraded more easily via traditional chemical means." #PFAS #CECs #Bioremediation

The newest paper from my PhD research just published in JECE shows that sulfate driven advanced oxidation water treatment systems can transform polyester microplastic fibres but are unlikely to fully remove them. Engineers developing treatment systems for microplastic removal need to consider if their system actually just creates nanoplastics and partially degraded fragments and think about the knock-on risks of this to the aquatic environment.

I am excited to share that our latest research article, "Enhanced g-C3N4 for Sustainable Solar Degradation of 1,3-Diphenylguanidine (DPG) in Wastewater: Investigating the Effects of Precursor, Temperature, and Potassium Doping," has been published in the Chemical Engineering Journal. In this study, we explored various approaches to enhance the efficiency of graphitic carbon nitride (g-C3N4) as a catalyst for solar-driven degradation of DPG, a common component of tire wear particles found in wastewater. Our research investigated the impact of precursor selection, synthesis temperature, and the significant effect of potassium doping. These findings hold promise for advancing sustainable solutions in water treatment, contributing to a cleaner environment. I extend my sincere gratitude to my supervisors, Dr. Yaman Boluk and Dr. Mohamed Gamal El-Din, for their invaluable support and guidance throughout this research journey.

I am thrilled to share our latest research publication in the Journal of Water Process Engineering (JWPE), titled "Construction of engineered heterojunction based on CdS and MgO material co-integrated into a flat plane-like graphene for tetracycline decontamination: Ecological hazard assessment and toxicity alleviation." Our study investigates a novel ternary CdS/MgO/graphene heterostructured composite (CMG) and its effectiveness in the photocatalytic decomposition of tetracycline (TTC) from aqueous environments under LED light illumination. With the rising concern over antibiotic residues in water systems and their severe threats to public health and ecosystems, our research addresses a critical environmental challenge. Notably, we conducted the first-ever assessment of probabilistic health hazards associated with TTC and its oxidation intermediates using the CMG/LED system, employing the hazard quotient (HQ) method. I extend my heartfelt gratitude to my colleagues for their invaluable contributions and guidance throughout this project.
