Improving the anaerobic digestion of sewage sludge by adding cobalt nanoparticles.

This work evaluated the effects of cobalt nanoparticles (CoNPs) (0.025-7 mg/g) on the intensification of sewage sludge anaerobic digestion (AD) using biochemical methane potential (BMP) tests. This study was motivated by the need to improve the efficiency and stability of anaerobic digestion of sewage sludge, a critical process in waste management and renewable energy production.

Influence of zero-valent iron nanoparticles on anaerobic digestion of swine manure: effects on methane yield.

This study evaluated the effect of zero-valent iron nanoparticles (NZVI) on the anaerobic digestion of swine manure. A wide range of doses of NZVI was evaluated (5, 10, 15, 20, 25, 50, and 100 mgFe°/gVS). The maximum methane yield of 0.

Similar Features, Different Behaviors: A Comparative In VitroStudy of the Adipogenic Potential of Stem Cells from Human Follicle, Dental Pulp, and Periodontal Ligament.

Dental tissue-derived mesenchymal stem cells (DT-MSCs) are a promising resource for tissue regeneration due to their multilineage potential. Despite accumulating data regarding the biology and differentiation potential of DT-MSCs, few studies have investigated their adipogenic capacity. In this study, we have investigated the mesenchymal features of dental pulp stem cells (DPSCs), as well as the in vitro effects of different adipogenic media on these cells, and compared them to those of periodontal ligament stem cells (PLSCs) and dental follicle stem cells (DFSCs).

Epigenetic Regulation of Adipogenic Differentiation by Histone Lysine Demethylation.

Obesity is a rising public health problem that contributes to the development of several metabolic diseases and cancer. Adipocyte precursors outside of adipose depots that expand due to overweight and obesity may have a negative impact on human health. Determining how progenitor cells acquire a preadipocyte commitment and become mature adipocytes remains a significant challenge.

Nanoferrosonication: A novel strategy for intensifying the methanogenic process in sewage sludge.

In this work, the effect of coupling ultrasonic pretreatment with dosing of zero-valent iron nanoparticles (nanoferrosonication, "NFS") to improve the anaerobic digestion of sewage sludge was studied. Biochemical methane potential tests were conducted at 15,000 and 25,000 kJ/kg and their combinations with 2 and 7 mgFe/g. The biogas yield increased from 106 (control) to 143 (25,000 kJ/kg) and 308 mL/g with NFS (7 mgFe/g + 15,000 kJ/kg).

Enhancing the performance and stability of the anaerobic digestion of sewage sludge by zero valent iron nanoparticles dosage.

This work studied the effects on the anaerobic digestion of sewage sludge by zero valent iron nanoparticles (NZVI) dosage. Biochemical methane potential tests were carried out with 5-9 mg/g (99.7%, 40-60 nm).
