Gas‐Phase Dehydrogenation of Perhydro Benzyltoluene Using a Commercial Pt on Alumina Catalyst–Stability and Kinetics

open access: yesEnergy Technology, Volume 14, Issue 3, March 2026.
Dehydrogenation of H12‐BT is normally conducted in a multiphasic reaction whereas hydrogen release lowers the partial pressure of H12‐BT and induces H12‐BT evaporation. Due to H12‐BT evaporation major parts of the released hydrogen origin from gas phase dehydrogenation.

Electrocatalytic Reduction and Oxidation Conversion of Plant Biomass

open access: yesSmall Structures, Volume 7, Issue 3, March 2026.
This review therefore establishes a unified “compound–catalyst–conversion” paradigm, systematically categorizing and analyzing electrocatalytic oxidation and reduction pathways for the three major classes of plant‐derived components—aromatics, aliphatics, and terpenoids—to provide a clear navigational map for the field.

Deuteron spin-lattice relaxation times in undercooled aqueous potassium- and cesium halide solutions [PDF]

open access: yes, 1988
Aqueous emulsions of potassium-and cesium halides in cycloalkane mixtures can be undercooled at a pressure of 225 MPa to temperatures around 170K. In these emulsions deuterium spin-lattice relaxation times T1 have been determined as function of salt ...
