Benign and Selective Amination of Lignins towards Aromatic Biobased Building Blocks with Primary Amines

open access: yesAngewandte Chemie, Volume 136, Issue 41, October 7, 2024.
This research article presents two new benign methodologies to access reactive and soluble lignin‐based polyamines. The aminated lignin products have potential as renewable building blocks in aromatic polymeric materials or as potential chelating, antibacterial agents, for instance. Abstract Lignin is a widely available second‐generation biopolymer and

Designing Physical Unclonable Functions From Optically Active Materials

open access: yesAdvanced Materials, Volume 37, Issue 49, December 10, 2025.
Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.

Lysosomal pH regulation in aging and neurodegenerative disease

open access: yesAlzheimer's &Dementia, Volume 21, Issue S7, December 2025.
Abstract Background The lysosome is critical for maintaining normal protein homeostasis in cells and has been genetically implicated in the pathogenesis of neurodegenerative diseases including Alzheimer's Disease and frontotemporal dementia. Lysosomes are normally highly acidic organelles and acidic lysosomal pH is critical for efficient macromolecular

The Lrs14‐Like AbfR1 Homolog From Metallosphaera sedula Is a Nucleoid‐Organizing Protein

open access: yesMicrobiologyOpen, Volume 14, Issue 5, October 2025.
Nucleoid organization in Crenarchaeota involves diverse small DNA‐binding proteins. The Lrs14‐type protein AbfR1 from Metallosphaera sedula binds nonsequence specifically across the genome and induces DNA condensation. These findings suggest a structural role for AbfR1Ms in chromatin architecture, functionally resembling bacterial nucleoid‐associated ...
