Can We Decarbonise Methanol Production by Direct Electrochemical CO2 Reduction?

open access: yesChemElectroChem, 2023
Methanol is one of the most important chemical feedstocks, with an increase in global demand of more than 20 million tonnes since 2017. The current production of methanol is primarily from fossil fuel derived synthetic gas (syngas), producing up to 2.97 ...

COMPILATION OF MOMENTS OF SPIN MAXIMA OF THE INTERMEDIATE POLAR EX HYA

open access: yesOdessa Astronomical Publications, 2013
We present a compilation of the spin maxima of the intermediate polar EX Hya determined using the same methods for our own observations from the Tzec Maun observatory, published observations from the SuperWASP, ASAS and AAVSO databases. For completeness,

Lessons learned from implementing the pilot Micronutrient Powder Initiative in four districts in Ghana

open access: yesBMC Nutrition, 2020
Background Micronutrient deficiencies affect many children in low-income settings due primarily to over-reliance on complementary foods low in nutrients. Home-fortification (HF) could improve children’s diet quality in these settings.

Switching imidazole reactivity by dynamic control of tautomer state in an allosteric foldamer

open access: yesNature Communications, 2023
Molecular biology achieves control over complex reaction networks by means of molecular systems that translate a chemical input (such as ligand binding) into an orthogonal chemical output (such as acylation or phosphorylation).

Maintaining and breaking symmetry in homomeric coiled-coil assemblies

open access: yesNature Communications, 2018
Higher order coiled coils with five or more helices can form α-helical barrels. Here the authors show that placing β-branched aliphatic residues along the lumen yields stable and open α-helical barrels, which is of interest for the rational design of ...

Electrochemical synthesis of biaryls by reductive extrusion from N,N’-diarylureas

open access: yesNature Communications, 2023
The synthesis of biaryl compounds by the transition-metal free coupling of arenes is an important contemporary challenge, aiming to avoid the toxicity and cost profiles associated with the metal catalysts commonly used in the synthesis of these ...
