Unidirectional MCM translocation away from ORC drives origin licensing

open access: yesNature Communications
The MCM motor of the eukaryotic replicative helicase is loaded as a double hexamer onto DNA by the Origin Recognition Complex (ORC), Cdc6, and Cdt1. ATP binding supports formation of the ORC-Cdc6-Cdt1-MCM (OCCM) helicase-recruitment complex where ORC ...

CO2 Adsorption on Mesoporous Silica Using Response Surface Methodology (RSM)

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The aim of the current study is to investigate the CO2 adsorption on the mesoporous silica. The adsorbent was characterized by XRD, TEM, SEM, and N2 adsorption desorption. The adsorption isotherms of carbon dioxide (CO2) on the silica were investigated using a static volumetric method at various temperatures.

Effect of Deliberate Physical Damage and Repair on the Icephobicity of Oil‐Infused Elastomer Coatings

open access: yesJournal of Applied Polymer Science, EarlyView.
Oil‐infused elastomer coating specimens are damaged by cutting or abrasion to study the effect on ice adhesion strength, freezing time and surface properties. The softer coatings show greater morphological changes but their icephobicity is no worse than coatings without oil‐infusion. Though damage causes deterioration in icephobicity, some icephobicity
