Solutions to a combined problem of excessive hydrogen sulfide in biogas and struvite scaling
, 2005 The Woodman Point Wastewater Treatment Plant (WWTP) in Western Australia has experienced two seperate problems causing avoidable maintenance costs: the build-up of massive struvite (MgNH4PO4′ 6H2O) scaling downstream of the anaerobic digester and the ...

Modifying the Substrate Specificity of Keratinase for Industrial Dehairing to Replace Lime-Sulfide
, 2022 Keratinase has shown potential as an ecofriendly alternative to toxic lime-sulfide for industrial dehairing. However, low substrate specificity usually causes collagen damage. Here, we developed a variant of keratinase KerZ1 with low collagenase activity

Advanced Functional Materials, EarlyView.When hydrated zinc ions are deposited onto Cu substrates at practical current densities, the modified Cu enables simultaneously compact zinc growth and suppressed hydrogen evolution. This regulatory effect originates from the superior adsorption of the modified Cu interface, which enhances zincophilicity and the hydrogen desorption barrier, thereby ...

Unsuspected diversity of Niphargus amphipods in the chemoautotrophic cave ecosystem of Frasassi, central Italy [PDF]
, 2010 Background: The sulfide-rich Frasassi caves in central Italy contain a rare example of a freshwater ecosystem supported entirely by chemoautotrophy. Niphargus ictus, the sole amphipod species previously reported from this locality, was recently shown to ...

Advanced Functional Materials, EarlyView.A Ni,Cd‐codoped Fe2VO4/NF bifunctional electrocatalyst is rationally designed for efficient seawater electrolysis. Synergistic effect modulates electron configuration, optimizes intermediates adsorption, stabilizes high‐valence Fe/V sites, and repels chloride ions to suppress corrosion and side reactions, thus contributing to performance improvement of
