Rapid Catalytic Recycling of Poly(ethylene terephthalate): Minimal Hydroxide, Minimal Biomass‐Derived Recyclable Cosolvent

open access: yesChemSusChem, EarlyView.
Furfuryl alcohol is shown to serve as a biomass‐based cosolvent par excellence for the alkaline hydrolysis of poly(ethylene terephthalate) (PET) bottle and PBA‐PC compact disk waste. The solvent can be recycled, used at low levels (3 mL g−1 PET), and operates in tandem with an efficient phase transfer catalyst to completely depolymerize PET at <100 °C ...

Transendocardial injection of expanded autologous CD34+ cells after myocardial infarction: Design of the EXCELLENT trial

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1455-1463, April 2025.
Abstract Aims The extent of irreversible cardiomyocyte necrosis after acute myocardial infarction (AMI) is a major determinant of residual left ventricular (LV) function and clinical outcome. Cell therapy based on CD34+ cells has emerged as an option to help repair the myocardium and to improve outcomes.

AEGIS AT CERN: MEASURING ANTIHYDROGEN FALL [PDF]

open access: yesCPT and Lorentz Symmetry, 2010
The main goal of the AEGIS experiment at the CERN Antiproton Decelerator is the test of fundamental laws such as the Weak Equivalence Principle (WEP) and CPT symmetry. In the first phase of AEGIS, a beam of antihydrogen will be formed whose fall in the gravitational field is measured in a Moire' deflectometer; this will constitute the first test of the
