Direct visualization of flowing biomass capture and release within a fibrous matrix

The capture and release of biomass in a high voidage fibrous microstructure: Mechanisms and shear stress levels

“…In the images presented, the morphology of the biomass deposit clearly changes with time. Additionally, a previous visualisation study [5], showed that small particles are re-entrained into the fluid flow. These two findings indicate that at least some of the particles that eventually break through to the effluent have been captured and subsequently sheared off.…”

“…We have also explored the use of oscillatory fluid flow for the detachment and re-suspension of these biomass aggregates. We have briefly reported on visualisation studies relating to biomass capture in high voidage fibrous filters [5] and also described aspects relating to the hydraulic response of the system [3]. In this paper, particle capture mechanisms are identified and by using confocal laser scanning microscopy (CLSM), void fractions and surface areas are determined within the high porosity filter.…”

Catechol‐containing waterborne polyurethane adhesive inspired by mussel proteins

“…10,11 This kind of adhesion inspiration from marine lives may provide a new idea for the development of environmentally friendly adhesives. [12][13][14] Adhesives are polymer-based chemicals used to connect two or more homogeneous or heterogeneous materials together, so they must have sufficient strength after curing to make the peeling strength be enhanced. 15 At present, most of adhesives used in leather industry are solventborne adhesives, for example, polyamide resin adhesive, polyurethane adhesive, and neoprene adhesive.…”

“…Therefore, it has become a research hotspot for how to introduce catechol units into the backbone of polymers to realize the biomimetic structure and function 10,11 . This kind of adhesion inspiration from marine lives may provide a new idea for the development of environmentally friendly adhesives 12–14 …”
