referenceDoug Ellison wrote an article titled 'Life's a bleach' for Planetary.org on August 24, 2007, discussing hydrogen peroxide as a potential solvent for life.
claimJoop M. Houtkooper and Dirk Schulze-Makuch proposed a hypothesis in 2007 regarding the potential for hydrogen peroxide (H2O2) and water (H2O) mixtures to support extremophiles on Mars.
claimIt has been proposed that life on Mars may exist using a mixture of water and hydrogen peroxide as a solvent.
claimJoop M. Houtkooper and Dirk Schulze-Makuch proposed a hypothesis in 2007 regarding a possible biogenic origin for hydrogen peroxide on Mars.
measurementA 61.2% (by mass) mixture of water and hydrogen peroxide has a freezing point of −56.5 °C, tends to super-cool rather than crystallize, and is hygroscopic.

procedureThe subcritical extraction method for valorizing Almond shells involves heating the feedstock at temperatures between 150–320 °C and pressures between 20–150 bar, followed by a bleaching step using 8% hydrogen peroxide (H2O2) at 160 °C or 180 °C.
measurementThe subcritical extraction of Almond shells followed by bleaching with 8% hydrogen peroxide results in a cellulose recovery of 71% with 50% crystallinity at 160 °C, and 78% recovery with 62% crystallinity at 180 °C.
referenceI. Gil-Guillén, P. A. V. Freitas, C. González-Martínez, and A. Chiralt obtained cellulose fibers from almond shells by combining subcritical water extraction and bleaching with hydrogen peroxide, as published in Molecules in 2024.
procedureThe process for recovering biomaterials begins with alkali (NaOH) pre-treatment, followed by steam explosion, and concludes with oxidation using 30% H2O2 and 3.7 wt% NaOCl.

claimGlutathione peroxidases (GPx) are selenoproteins that function as redox regulators and cellular antioxidants by reducing reactive oxygen species, such as hydrogen peroxide and lipid hydroperoxides, to harmless products like water and alcohols through the oxidation of glutathione.
