In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Carbon capture and storage [PDF]

, 2009
All over the world, climate change is regarded as one of the most important environmental problems faced by the planet. It is now accepted that mankind, through the emission of certain trace gases, has a significant influence on climatic conditions (anthropogenic greenhouse effect) and that the average global temperature of the earth will rise in the ...

Modelling of carbon dioxide absorption in hollow fiber membrane contactor for different flow configurations

Results in Engineering
In the study of gas absorption using hollow fiber membrane contactor (HFMC), quantitative analysis between the parallel flow and crossflow configurations remains unclear, leading to difficulty in understanding the mass transfer behaviour in membrane ...

Process intensification for post combustion CO₂ capture with chemical absorption: a critical review [PDF]

, 2015
The concentration of CO₂ in the atmosphere is increasing rapidly. CO₂ emissions may have an impact on global climate change. Effective CO₂ emission abatement strategies such as carbon capture and storage (CCS) are required to combat this trend.

Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.
