Unsteady-state Computational Fluid Dynamics Modeling of Hydrogen Separation from H2/N2 Mixture [PDF]
Journal of Chemical and Petroleum Engineering, 2017 3D modeling of Pd/α-Al2O3 hollow fiber membrane by using computational fluid dynamic for hydrogen separation from H2/N2 mixture was considered in steady and unsteady states by using the concept of characteristic time.

FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Hydrogen separation in La5.5WO11.25−δ membranes
Journal of Membrane Science, 2013 Tungstates Ln(6)WO(12) are proton conducting crystalline materials which show significant mixed protonic and electronic conductivity and stability in moist CO2 environments. These materials are promising candidates for hydrogen separation membranes at temperatures above 700 degrees C, especially when integrated in intensified processes as catalytic ...

Is the proton radius puzzle evidence of extra dimensions? [PDF]
, 2016 The proton charge radius inferred from muonic hydrogen spectroscopy is not compatible with the previous value given by CODATA-2010, which, on its turn, essentially relies on measurements of the electron-proton interaction.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions
FEBS Letters, EarlyView.We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Study and Development of a Mini-Tube Gas Separator Utilizing the Soret Effect
Journal of Thermal Science and Technology, 2012 The Soret effect is a phenomenon in which a temperature gradient gives rise to a concentration gradient. In this study, we attempted a simple technique for the separation of hydrogen from a gas mixture by utilizing the Soret effect.

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Effects of Helium Phase Separation on the Evolution of Extrasolar Giant Planets
, 2004 We build on recent new evolutionary models of Jupiter and Saturn and here extend our calculations to investigate the evolution of extrasolar giant planets of mass 0.15 to 3.0 M_J.
