Some technical aspects of the rheological properties of high concentration fine suspensions to avoid environmental disasters

open access: yesJournal of Environmental Engineering and Landscape Management, 2015
The behavior of slurries and suspensions made by mixing solid particles and liquids is very important for various industrial applications. The latest accidental failure events at tailings facilities (Kolontár, Baia Mare) have focused public interest into

Thermostable neutral metalloprotease from Geobacillus sp. EA1 does not share thermolysin's preference for substrates with leucine at the P1′ position

open access: yesFEBS Letters, EarlyView.
Knowing how proteases recognise preferred substrates facilitates matching proteases to applications. The S1′ pocket of protease EA1 directs cleavage to the N‐terminal side of hydrophobic residues, particularly leucine. The S1′ pocket of thermolysin differs from EA's at only one position (leucine in place of phenylalanine), which decreases cleavage ...

From Critical Raw Materials to Circular Raw Materials

open access: yesChemSusChem
AbstractThis perspective addresses the key challenge of advancing the use of Critical Raw Materials (CRMs) and proposes a transition towards circular raw material management. In the context of our current economy, the unsustainable consumption, environmental degradation, geopolitical risks, and economic vulnerabilities associated with CRMs highlight ...

Exploring lipid diversity and minimalism to define membrane requirements for synthetic cells

open access: yesFEBS Letters, EarlyView.
Designing the lipid membrane of synthetic cells is a complex task, in which its various roles (among them solute transport, membrane protein support, and self‐replication) should all be integrated. In this review, we report the latest top‐down and bottom‐up advances and discuss compatibility and complexity issues of current engineering approaches ...
