Survey of Interlayer Interaction Models for Graphene and 2D Materials
Researchers from IIT Kanpur, Ruhr University Bochum, and IIT Guwahati have published a 55-page survey in Advanced Materials Interfaces cataloguing mechanical models that describe van der Waals interlayer interactions in graphene and other two-dimensional materials. The review covers both atomistic and continuum approaches to normal and tangential contact, addressing phenomena such as Moiré patterns, superlubricity, and surface reconstructions. It is particularly relevant to the field of multiscale modeling, where reducing computational cost remains a central challenge.
The survey, authored by Gourav Yadav, Shakti S. Gupta, and Roger A. Sauer, systematically reviews the landscape of models used to describe van der Waals (vdW) interactions between two-dimensional materials, with graphene as a primary focus. The work addresses both continuous elastomer-like and discrete crystalline material frameworks, organizing the discussion around normal contact models followed by tangential contact models. Physical phenomena arising from these interlayer interactions—including contact instabilities, Moiré patterns, surface reconstructions, and superlubricity—are examined in detail. The authors analyze how external loading and changes in length scale affect ground-state configurations and frictional contact behavior. A significant portion of the survey is devoted to computational strategies that reduce the cost of multiscale simulations, a practical concern given the complexity of modeling atomistic-to-continuum transitions in layered 2D systems. The paper spans 55 pages and includes 25 figures, and has been published in Advanced Materials Interfaces (2026). It serves as a reference resource for researchers working at the intersection of computational mechanics, materials science, and nanotribology.
What's missing
The survey is a review article rather than an original experimental or simulation study, so it does not report new empirical results or validation benchmarks of its own. Readers should note that the coverage of models may reflect the authors' selection criteria and scope.

Gut Bacteria Enzyme Found to Break Down Heat-Processed Food Compounds, Producing Novel Biogenic Amines
Researchers have discovered that an enzyme in common gut bacteria can degrade N-epsilon-carboxymethyllysine (CML), a compound formed during thermal food processing, producing previously unknown biogenic amines. The enzyme, ornithine decarboxylase SpeC from enterobacteria, acts on CML and related modified lysine derivatives through a low-level 'underground' catalytic activity. This finding suggests a previously unrecognized communication axis between thermally processed dietary compounds and gut microbial physiology, with potential implications for host health.
Full-Length Gene Sequencing Reveals Two Distinct Bacterial Communities in Black-Legged Ticks Expanding Into Canada
Researchers used Oxford Nanopore full-length 16S rRNA gene sequencing to characterize the microbiome of Ixodes scapularis black-legged ticks collected in Nova Scotia, Canada, distinguishing between tick-adapted bacteria and environmentally acquired bacteria. The study comes as I. scapularis — the primary vector of Lyme disease — is rapidly expanding northward into Canada due to climate change. The findings suggest that environmentally derived bacteria in tick microbiomes are not mere contamination, which has implications for how tick microbiome data is collected and interpreted across surveillance studies.
Study Identifies Metabolic Link Between Cell Envelope Stress and Biofilm Formation in Bacteria
Researchers have discovered that the metabolite acetyl-CoA directly inhibits enzymes that degrade the bacterial signaling molecule c-di-GMP, connecting cell envelope biosynthesis stress to biofilm formation in Pseudomonas aeruginosa. The study found that sub-inhibitory concentrations of antibiotics targeting early peptidoglycan biosynthesis — but not other antibiotic classes — elevate c-di-GMP levels by reducing phosphodiesterase activity, with acetyl-CoA competing for the enzyme active site. Because the relevant enzyme domain is broadly conserved across bacterial species, this checkpoint mechanism may be widespread and could have implications for understanding antibiotic-induced biofilm responses.
