ItemScum formation and consolidation in covered anaerobic lagoonsSTICKLAND, AD ; LESTER, DR ; Eshtiaghi, N ; Bobade, V ; Das, T ; USHER, SP ; REES, C ; McMurrich, D (Australian Water Association, 2022)Scum builds up in covered anerobic lagoons that reduces hydraulic retention time, inhibits biogas capture, and damages lagoon covers. We demonstrate that the majority of this biomass sinks when degassed, indicating it mostly consists of undigested sludge floated by biogas. Thus, scum accumulation is inevitable and is not prevented by source control of fats, oils and floating debris; scum must be periodically and mechanically removed. We develop a theory of scum consolidation and desaturation driven by buoyancy and evaporation, and measure scum permeability and compressibility, to predict scum behaviour. Continued scum accumulation leads to densification and eventually crusting. The recommended scum management technique involves frequent agitation at low accumulation to liberate biogas, sinking biomass to digest it.

ItemHierarchical Self-Assembly of Peptides and its Applications in BionanotechnologyGerbelli, BB ; Vassiliades, SV ; Rojas, JEU ; Pelin, JNBD ; Mancini, RSN ; Pereira, WSG ; Aguilar, AM ; Venanzi, M ; Cavalieri, F ; Giuntini, F ; Alves, WA (WILEY-V C H VERLAG GMBH, 2019-07-19)Self‐assembled structures obtained from organic molecules have shown great potential for applications in a wide range of domains. In this context, short peptides prove to be a particularly versatile class of organic building blocks for self‐assembled materials. These species afford the biocompatibility and polymorphic richness typical of proteins while allowing synthetic availability and robustness typical of smaller molecules. At the nano‐to‐mesoscale, the architectures obtained from peptide units exhibit stability and a large variety of morphologies, the most common of which are nanotubes, nanoribbons, and nanowires. This review describes the formation of peptide‐based self‐assembled structures triggered by different stimuli (e.g., ionic strength, pH, and polarity), and the interactions that drive the assembling processes. It is surveyed how judicious molecular design is exploited to impart favourable assembling properties to afford systems with desired characteristics. A large body of literature provides the experimental and in silico data to predict self‐assembly in a given peptide system and obtain different supramolecular organizations for applications in a wide range of fields, from transport to sensing, from catalysis to drug delivery and tissue regeneration.
