Enterolyin S, a Polythiazole‐containing Hemolytic Peptide from Enterococcus caccae [PDF]
ChemBioChem, Volume 25, Issue 12, June 17, 2024.The Streptolysin S (SLS)‐type of linear azol(in)e‐containing peptides (LAPs) belong to a family of ribosomally synthesized and post‐translationally modified peptides (RiPPs) known for their hemolytic activities. The chemical structure of SLS has remained elusive despite its discovery 85 years ago.

Analytical and numerical modeling of the Cyclic ES-SAGD process
, 2019 The world is still highly dependable on the energy that comes from oil. The current demand for energy has given importance to oil reservoirs that were normally overlooked in the past due to its properties. One example is found in the Canadian heavy oil sands.

Impact of Shale Barriers on SAGD and ES-SAGD Performance
, 2022 Shales are the common type of heterogeneity present in the oil sand reservoirs. Shale barriers usually have very low permeability leads to obstruction for fluid flow inside the reservoirs towards the wellbore. SAGD (steam assisted gravity drainage) and ES-SAGD (expanding solvent assisted gravity drainage) rely heavily on gravity drainage, and thus the ...

Triblock Polymer Engineering Enables Hydration‐Rich, High‐Performance, Fouling‐Resistant Interfaces
Advanced Functional Materials, Volume 36, Issue 36, 4 May 2026.A molecularly engineered triblock polymer (PHZ) rapidly reorganizes into a hydration‐rich interfacial layer on diverse surfaces, strongly suppressing hydrophobic attraction and fouling. The triblock polymer provides robust energy and steric barriers to oily foulants, enabling high‐performance antifouling at ultralow dosage.

The Canadian Journal of Chemical Engineering, Volume 104, Issue 1, Page 425-441, January 2026.Abstract Solvent‐assisted recovery methods have gained attention as an alternative to conventional thermal methods which have significant environmental drawbacks and high greenhouse gas emissions. Solvent‐assisted recovery methods can lead to various phase equilibria, such as vapour–liquid equilibrium (VLE) and liquid–liquid equilibrium (LLE), under ...
