We Licked the Toads so You Don’t Have to: A Comprehensive Analysis of the Chemical Syntheses of the Classical Psychedelics Bufotenin(e) and 5‐Methoxy‐N,N‐Dimethyltryptamine

ChemMedChem, Volume 21, Issue 4, 25 February 2026.
The psychedelics 5‐MeO‐DMT and bufotenin—famously secreted by some toads—have been made in many different ways since 1936. Bufotenin (also spelt as bufotenine) and its methylated derivative, 5‐methoxy‐N,N‐dimethyltryptamine (5‐MeO‐DMT), are potent psychedelics that are found in many plants but also excreted by some species of toads.

Thermal decomposition of ammonium perchlorate catalyzed with CuO nanoparticles

Defence Technology, 2019
Ammonium perchlorate (APC) is the most common oxidizer in use for solid rocket propulsion systems. However its initial thermal decomposition is an endothermic process that requires 102.5 J·g−1. This manner involves high activation energy and could render

Biodegradation of rocket propellant waste, ammonium perchlorate [PDF]

The short term effects of ammonium perchlorate on selected organisms were studied. A long term experiment was also designed to assess the changes incurred by ammonium perchlorate on the nitrogen and chloride contents of soil within a period of 3 years ...

Year‐round rhythms: Alpine plant species modulate soil and microbial dynamics during the growing season and under the snow

Ecological Monographs, Volume 96, Issue 1, February 2026.
Abstract Soil–plant–microbe interactions are integral throughout most terrestrial ecosystems, yet the importance of plant phenology and seasonal dynamism upon these relationships remains unknown. Given the pronounced seasonality of alpine environments, we sampled eight plant species occurring in two habitats (alpine meadow and subnival zone) across ...

Electrocarboxylation in supercritical CO2 and CO2-expanded liquids [PDF]

, 2008
In this study, the electrocarboxylation of benzyl chloride in pressurized CO2, or pressurized mixtures of dimethylformamide (DMF) and CO2, was investigated in order to synthesize phenylacetic acid.

Ion‐Selective Electrode Robustness to Environmental Conditions Relevant to Spaceflight Missions to the Outer Solar System

Electroanalysis, Volume 38, Issue 2, February 2026.
Future in situ missions to ocean worlds of the outer solar system would benefit from the aqueous chemical measurements provided by ion‐selective electrodes (ISEs). Here, we verify the performance of ISEs after exposure to environments expected during outer Solar System missions, specifically near‐decade scale transit times, anhydrous conditions, low ...

Impacts of metal oxide crystalline structure on the decomposition of solid propellants under combustion heating rates

Fuel Communications
Ammonium perchlorate (AP) has been the oxidizer of choice for composite solid propellants for decades and has been the object of decomposition studies for safety monitoring.

ADN – The new oxidizer around the corner for an environmentally friendly smokeless propellant [PDF]

Journal of Aerospace Technology and Management, 2009
The search for a smokeless propellant has encouraged scientists and engineers to look for a chlorine-free oxidizer as a substitute for AP (ammonium perchlorate).
