A highly enantioselective anti-diastereoselective hetero-Diels−Alder reaction between a glyoxylate and siloxy- or methoxydienes using a chiral phosphoric acid catalyst that possesses less bulky phenyl ...

Phosphoric acid group, which possesses a low energy barrier for proton conduction and high water bonding energy, favors proton conduction and water retention. In this study, a phosphoric acid porous ...

A steady-state simulation of wet phosphoric acid concentration process was carried out. The electrolyte-NRTL model was used to calculate the activity coefficients of species considered in the aqueous ...

Modern re-run shows that Arthur Ruhlig’s conclusions, which probably influenced early thinking about fusion energy, were ...

Cellulosic insulating paper is the essential component of the insulation in power transformers. Under the thermal stress inside the transformer, the cellulosic insulating paper degrades and generates ...

• Egypt to launch $573 million project to produce phosphoric acid for fertilizers • First phase to yield 250,000 tons annually; commercial output expected in 2028 • Project aims to cut imports and ...

A Los Alamos collaboration has replicated an important but largely forgotten physics experiment: the first deuterium-tritium ...

Global sulfur demand totalled just over 71 million t in 2024, with 60% of this for the production of fertilizers. Phosphoric acid leads the sector, used in the production of downstream processed ...

A product used on farms across New York, produced at a facility in Chateaugay, was nearly banned for use on agricultural land ...
