Preparation and anti-corrosion Properties of SiO2@MWCNTs@PFOTES Superhydrophobic Coatings on Magnesium Alloy

open access: yesInternational Journal of Electrochemical Science, 2022
Inspiration from nature provides the combination of micro-nano particles and low surface energy materials, a spraying method has been employed to prepare SiO2@MWCNTs@PFOTES superhydrophobic coatings on magnesium alloy, which can enhance corrosion ...

Spatial variability of climate and past atmospheric circulation patterns from central West Antarctic glaciochemistry [PDF]

open access: yes, 1999
Atmospheric circulation patterns and the spatial variability of atmospheric chemistry and moisture transport in central West Antarctica are investigated using new 40 year long (1954–1994 A.D.) glaciochemical and accumulation rate records developed from ...

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Comparative Study of the Competitive Adsorption of Mg, Ca and Sr Ions onto Resins

open access: yesAdsorption Science & Technology, 2013
Existing studies on the adsorption of alkaline earth metal ions have mainly focused on the adsorption of one alkaline earth metal ion. However, under natural conditions, alkaline earth metal ions usually co-exist. While separating them using an adsorbent,

How does the local wind field control the aerosol distribution in coastal Dronning Maud Land? [PDF]

open access: yes, 2011
Atmospheric circulation patterns and chemical concentrations in firn cores are highly related to each other. Atmospheric winds transport aerosols like sea salt and mineral dust over the globe and redistribute them.

Activity of water in aqueous systems; A frequently neglected property [PDF]

open access: yes, 2005
In this critical review, the significance of the term ‘activity’ is examined in the context of the properties of aqueous solutions. The dependence of the activity of water(ℓ) at ambient pressure and 298.15 K on solute molality is examined for aqueous ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Inclusion of chemical effect in a fully coupled THM finite element code [PDF]

open access: yes, 2018
Bentonite-rich clays can be used as a buffer / backfill material in deep geological repositories for nuclear waste. The prediction of the long-term performance of a buffer / backfill in such a complex environment, where the temperature, humidity and ...

Long-lived submicrometric bubbles in very diluted alkali halide water solutions

open access: yes, 2012
Solutions of LiCl and of NaCl in ultrapure water were studied through Rayleigh/Brillouin scattering as a function of the concentration (molarity, M) of dissolved salt from 0.2M to extremely low concentration (2.10^-17 M ).
