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).

Achieving Wide-Temperature-Range Physical and Chemical Hydrogen Sorption in a Structural Optimized Mg/N-Doped Porous Carbon Nanocomposite

Nano-Micro Letters
Highlights The as-synthesized rN-pC exhibited H2 uptake of ~0.9 wt% at 77 K and ultralow pressure of ~0.1 bar, with an isosteric adsorption enthalpy (Qst) of ~14 kJ mol-1 H2 at zero coverage.

Computational screening of transition metal-doped CdS for photocatalytic hydrogen production

npj Computational Materials, 2022
A novel computational screening study of single transition metal (TM), TM-doped, and dual TMs-doped on CdS (110) surfaces via DFT calculations is presented, focusing on their stability and catalytic activity, searching for efficient photocatalysts for ...

Investigation on the physical and electrochemical properties of typical Ni-based alloys used for the bipolar plates of proton exchange membrane fuel cells

Heliyon, 2023
The phase, mechanical properties, corrosion resistance, hydrophobicity, and interface contact resistance of three typical Ni-based alloys (Hastelloy B, Hastelloy C-276, and Monel 400) and 304 stainless steels were experimentally studied to evaluate their

Hydrogen bond network connectivity in the electric double layer dominates the kinetic pH effect in hydrogen electrocatalysis on Pt

Nature Catalysis, 2022
The origin of the large kinetic pH effect in hydrogen electrocatalysis, that is, the approximately two orders of magnitude decrease in reaction kinetics when moving from acid to alkaline, remains far from having a consensus.

Hydrogen microstructure in hydrogenated amorphous silicon [PDF]

Physical Review B, 1996
We present a method to determine the local hydrogen bonding structure in hydrogenated amorphous silicon from infrared spectroscopy measurements. This approach is based on a different oscillator strength and refractive index for hydrogen atoms located in the isolated and clustered phase.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

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 ...

Modelling ultrasound waves bubble formation in ethanol/ethyl acetate azeotrope mixture [PDF]

E3S Web of Conferences, 2019
The separation of an azeotropic mixture such as ethanol/ethyl acetate in distillation process can be enhanced by ultrasound wave. The application of ultrasound wave creates bubble cavitation in the mixture and shifts the vapour-liquid equilibrium ...
