Preyssler Heteropolyacids in the Self-Etherification of 5-Hydroxymethylfurfural to 5,5′-[Oxybis(methylene)]bis-2-furfural Under Mild Reaction Conditions [PDF]
, 2017 The synthesis of 5,5′-[oxybis(methylene)]bis-2-furfural (OBMF) from 5-hydroxymethylfurfural (5-HMF) was studied using bulk and alumina-supported Preyssler heteropolyacids (HPAs). The formation of OBMF was related to the amount of Brønsted acid sites, and

Modeling of Heliospheric Modulation of Cosmic-ray Positrons in a Very Quiet Heliosphere [PDF]
, 2018 Heliospheric modulation conditions were unusually quite during the last solar minimum activity between Solar Cycles 23/24. Fortunately, the PAMELA space-experiment measured six-month averaged Galactic positron spectra for the period July 2006 to December

Angewandte Chemie, EarlyView.Through ligand length and π‐electron density modulation, metal–organic frameworks (MOFs) improve mass transport and hydrogen atom transfer (HAT), thus improving biomass electrooxidation. ABSTRACT Controlling reaction pathways in electrocatalytic biomass upgrading remains challenging because mass transport, substrate adsorption, and elementary kinetics ...

Microscopic dynamics of a phase transition: equilibrium vs out-of-equilibrium regime [PDF]
, 2000 We present for the first time to the nuclear physics community the Hamiltonian Mean Field (HMF) model. The model can be solved analytically in the canonical ensemble and shows a second-order phase transition in the thermodynamic limit.
