Corn cob pyrolysis: A systematic literature review of methods and applications

The Canadian Journal of Chemical Engineering, EarlyView.
Mapping the research landscape of corn cob pyrolysis. Abstractas The agricultural sector is experiencing a surge in waste generation due to population growth, creating an urgent need to convert byproducts into value‐added products. Maize (Zea mays L.), a leading global crop, produces significant byproducts, such as corn cob, which are often undervalued.

Sustainable Synthesis, Characterization, Cellular Effects of Gold Nanoparticles and Their Applications as Therapeutics in Cancer Therapy

ChemPlusChem, EarlyView.
Gold nanoparticles (AuNPs) are widely used in biomedicine, electronics, catalysis, and environmental science. Conventional synthesis relies on harsh chemicals, driving interest in eco‐friendly methods using plants, bacteria, fungi, and algae. Biomolecules like polyphenols, proteins, and fatty acids aid nanoparticle synthesis under mild conditions. This

Controlling Lampenflora in Heritage Sites: In Situ Testing of Polyoxometalate–Ionic Liquids in the Pommery Champagne Cellar

ChemPlusChem, EarlyView.
The article evaluates polyoxometalate–ionic liquids (POM–ILs) as biocidal agents against lampenflora in the UNESCO‐listed Pommery Champagne cellar. POM–ILs effectively inhibit microbial colonization over one year with minimal visual impact and outperform the commercial biocide Preventol RI80.

The Impact of Redox Mediators on the Electrogenic and Physiological Properties of Synechocystis sp. PCC 6803 in a Biophotovoltaic System

ChemSusChem, EarlyView.
Redox mediators are essential to promote the electrogenic activity of cyanobacteria in biophotovoltaics. In this work, we systematically evaluates three representative mediators about their influence on the cyanobacterial growth, photosynthetic efficiency, and electrogenic activity. The results reveal distinct impacts of different mediators, despite of
