Chemistry – A European Journal, EarlyView.One‐pot synthesis of asymmetric organic carbonates from CO2, methanol, and other alcohols was demonstrated in the presence of CeO2 catalyst and 2‐cyanopyridine dehydrant. This reaction proceeded through two reaction pathways—direct route via cross‐carboxylation and indirect route via production of DMC and subsequent transesterification.

HELP: a sparse error locator polynomial for BCH codes [PDF]
, 2020 In 1990 Cooper suggested to use Groebner bases’ computations to decode cyclic codes and his idea gave rise to many research papers. In particular, as proved by Sala-Orsini, once defined the polynomial ring whose variables are the syndromes, the ...

A proof of the "Axis of Evil Theorem" for distinct points
, 2014 In this work we provide a complete and constructive proof of Marinari-Mora’s “Axis of Evil Theorem”. Given a finite set X ⊆ A^n(k) of distinct points and fixed on P := k[x1 , ..., xn ] the lexicographical order, the theorem states that one can produce ...

A study of Ni‐Co/CeO2 catalyst derived from metal–organic framework for dry reforming of methane
The Canadian Journal of Chemical Engineering, EarlyView.Abstract The efficacy of cobalt‐doped, MOF‐derived catalysts for dry reforming of methane (DRM) was examined. The focus was on the influence of varying nickel and cobalt molar ratios on catalytic performance. Three catalysts with Ni:Co ratios of 1:1, 1:0.5, and 0.5:1, were synthesized and tested with cerium oxide as a constant support. The DRM reaction

The direct sum of q-matroids [PDF]
For classical matroids, the direct sum is one of the most straightforward methods to make a new matroid out of existing ones. This paper defines a direct sum for q-matroids, the q-analogue of matroids.

Revisiting the synthesis of dimethyl carbonate from methanol and carbon dioxide
The Canadian Journal of Chemical Engineering, EarlyView.Abstract The process for producing dimethyl carbonate (DMC) from carbon dioxide (CO2) and methanol is explored in this article. It provides an overview of the thermodynamics involved in DMC synthesis, discussing the challenges and potential solutions. The article highlights the reported use of catalysts and dehydrating agents to improve DMC yield and ...

A comparison of ceria and Sm-doped ceria for hydrocarbon oxidation reactions
Applied Catalysis A: General, 2004 Abstract The oxidation of methane, ethane, propane, and n -butane has been studied over CeO 2 and Samaria-doped ceria (SDC) catalysts. The rates for methane and ethane were found to be indistinguishable over the two catalysts, while the rates for propane and n -butane were much higher on ceria compared to SDC.

EcoEnergy, EarlyView.Subnanoscale CeO2‐Cu2O particles can efficiently catalyze the hydrogenation of the key intermediate *CO to CH4 at an impressive rate of 2818 μmol g−1 h−1 in photothermal CO2 reduction. ABSTRACT Water‐mediated photothermal CO2 reduction to CH4 is promising for renewable energy storage and carbon neutrality, but its selectivity and efficiency are limited
