Hydrogen storage in nickel doped MCM-41 [PDF]

open access: yes, 2013
Hydrogen as an energy carrier is one of the best environmentally friendly alternatives to fossil fuel sources. The potential use of hydrogen results with increasing demand to hydrogen production and storage. Recent studies show that materials having high

Quantitative characterization of pore structure of several biochars with 3D imaging

open access: yes, 2017
Pore space characteristics of biochars may vary depending on the used raw material and processing technology. Pore structure has significant effects on the water retention properties of biochar amended soils.

Pore Structure of Iron Oxides [PDF]

open access: yesBulletin of the Chemical Society of Japan, 1978
Abstract The pore structure of iron oxides, subjected to oxidation into α-Fe2O3 as well as reduction into Fe3O4, was investigated by means of the t-method. The results show that the reduction is accompanied by the formation of slit-shaped pores, width 14 Å, open at both ends.

Molecular bases of circadian magnesium rhythms across eukaryotes

open access: yesFEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Influence of Pore Structure Characteristics of Primary Coal on Coalbed Methane Adsorption

open access: yesAdvances in Materials Science and Engineering, 2022
In order to better discuss the influence of pore structure characteristics of primary coal on coalbed methane adsorption, suburban coal and Zhaozhuang coal in Henan Province were systematically sampled.

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10

open access: yesFEBS Letters, EarlyView.
Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...

Effect of pore structure on capillary condensation in a porous medium [PDF]

open access: yes, 2009
The Kelvin equation relates the equilibrium vapor pressure of a fluid to the curvature of the fluid-vapor interface and predicts that vapor condensation will occur in pores or irregularities that are sufficiently small.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Mechanism of microstructural modification of the interfacial transition zone by using blended materials [PDF]

open access: yes, 2015
Applying blended materials with finer particle size or high reactivity could be an effective and economic way for improving the microsturcture of interfacial transition zone (ITZ).
