Chemically Engineered Carbon Nanotubes Map Class-Selective Metabolite Enrichment from Human Plasma
The spontaneous adsorption of biomolecules onto nanoparticle surfaces has been extensively characterized at the protein level, but the metabolite corona remains poorly defined while being physicochemically and biologically distinctive. Herein, we report the first class-level mapping of metabolite corona composition across 25 chemically modified carbon nanotubes in human plasma using untargeted liquid chromatography-mass spectrometry. Complementary analytical conditions detected approximately...
Rule-based autocorrection of Piping and Instrumentation Diagrams (P&IDs) on graphs
arXiv:2502.18493v2 Announce Type: replace Abstract: A piping and instrumentation diagram (P&ID) is a central reference document in chemical process engineering. Currently, chemical engineers manually review P&IDs through visual inspection to find and rectify errors. However, engineering projects can involve hundreds to thousands of P&ID pages, creating a significant revision workload.
Most exoplanets might be 'soot factories,' scientists say: 'Like you have a natural diesel engine'
Most exoplanets might be 'soot factories,' scientists say: 'Like you have a natural diesel engine' A chemical engineer noticed that the spectra of the hazy atmosphere of mini-Neptune planets looked like the soot produced by combustion engines. Vast clouds of soot that form in the pressure cooker of mysterious mini-Neptune exoplanets may hold the truth about these worlds' origins. "It's like you have a natural diesel engine in the deep atmosphere of a planet," lead author of a study about...
Manchester University to offer work placements to all undergraduates
The University of Manchester is set to offer work placements to all undergraduate students, regardless of their field of study. This initiative aims to provide students, from chemical engineering to classics, with meaningful real-world experience to better prepare them for the job market. This move is noted as a potential first for a large Russell Group university.
Q&A: Are plants the key to solving energy and food crises worldwide?
Q&A: Are plants the key to solving energy and food crises worldwide? Lisa Lock Scientific Editor Andrew Zinin Lead Editor Changing market conditions are increasing the need for cost-effective ways to produce biorenewable chemicals, biofuels and materials that can serve as alternatives to oil-based products. According to Costas Maranas, Robert V. and Gloria H. Waltemeyer Chair and Donald B. Broughton Professor of Chemical Engineering at Penn State, solutions to these problems could come from...
Mapping Chemical Diversity: Descriptor-Guided Clustering of Natural Products in the COCONUT Database
Natural products represent a major source of bioactive compounds for drug discovery, yet their exploration remains challenging due to extensive structural complexity and scaffold diversity. Using the COCONUT database, we developed a cluster-oriented framework to systematically map and characterize the natural product chemical space through feature engineering, molecular clustering, and representative-based analysis. Descriptor selection identified a greedy maximum coverage strategy with a...
What's gonna happen to software engineers?
In the back of my mind, I've been thinking a lot about what's going to happen to software developers. In a metaphoric way it feels like an existential question, given that, well, I'm a software developer. The real answer is that nobody really knows.
Graph-to-SFILES: Control structure prediction from process topologies using generative artificial intelligence
arXiv:2412.00508v2 Announce Type: replace Abstract: Control structure design is an important but tedious step in P&ID development. Generative artificial intelligence (AI) promises to reduce P&ID development time by supporting engineers. Previous research on generative AI in chemical process design mainly represented processes by sequences.
