Stability, Adsorption and Diffusion of CH4, CO2 and H2 in Clathrate Hydrates
, 2010 We present a study of the adsorption and diffusion of CH4, CO2 and H2 molecules in clathrate hydrates using ab initio van der Waals density functional formalism [Dion et al. Phys. Rev. Lett. 92, 246401 (2004)].

CO2 Capture Partner Molecules in Highly Loaded PEI Sorbents [PDF]
, 2017 Decoupling amine loading from diffusion resistance is one of the main challenges in the development of immobilised amines CO2 sorbents. Water has been reported to serve this goal alleviating CO2 diffusional hindrance in highly loaded amine sorbents ...

Diffusion of dissolved CO2 in caprock
Energy Procedia, 2009 AbstractDiffusion of dissolved CO2 is a possible transport mechanism in caprocks which should be evaluated precisely for long term storage of CO2. It is also a mechanism controlling the caprock geochemical reactivity in the vicinity of the top of the storage where CO2 accumulates driven by gravity.

Transport Mechanisms for CO2-CH4 Exchange and Safe CO2 Storage in Hydrate-Bearing Sandstone
Energies, 2015 CO2 injection in hydrate-bearing sediments induces methane (CH4) production while benefitting from CO2 storage, as demonstrated in both core and field scale studies.

Use of nanoporous ceramic membranes for carbon dioxide separation [PDF]
, 2016 Natural gas processes accounts for about 5.3 billion tonnes per year of carbon dioxide (CO2) emission to the atmosphere. At this rate of emission, the expectation will drastically rise if not curtailed.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane
FEBS Letters, EarlyView.Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.
