Biomimetic approach to anti-fouling surfaces
… in the oil and gas sector. There are many approaches to remove and prevent scaling with chemical inhibition, chemical scale removers and mechanical methods being the most prevalent ones. Recently the focus has shifted onto more environmentally friendly inhibitors that are less toxic to the …

Biomimetic approach to cardiac tissue engineering
(cont.) biochemical and morphological properties in the pretreated group. Finally, in order to mimic capillary structure cardiac fibroblasts and myocytes were co-cultured on a scaffold with a parallel channel array that was perfused with culture medium supplemented with synthetic oxygen carrier …

An Investigation of Avian Wing Tip Vortex Generation Using a Biomimetic Approach
<p>An experimental study has been conducted to develop a process allowing the creation of biologically accurate aerodynamic test models mimicking the slotted primary feather geometry of the Brown Pelican (<em>Pelecanus occidentalis</em>). Preserved examples of both a full Brown Pelican wing and a …

Total synthesis and study of myrmicarin alkaloids
… Key transformations in this convergent approach include a stereospecific palladium-catalyzed N-vinylation of a pyrrole with a vinyl triflate, a copper-catalyzed enantioselective conjugate reduction of a P-pyrrolyl enoate, and a regioselective Friedel-Crafts reaction. The synthesis of …

Effects of a powered ankle prosthesis on shock absorption and residual limb/socket interface pressure
… has been reached. Further strides require a more biomimetic approach. Through integration of "smart" technology (sensors and actuators), a new phase of bionic lower-limb prostheses is upon us, which enables prosthetic devices to more closely mimic biological behavior by generating human-like …

Biomimicry in Leadership: How Healthy Leaders Facilitate Healthy Organisational Ecosystems– Lessons from Keystone Species
… of behaviour in keystone species can inform a biomimetic approach to healthy leadership that supports resilience. Keystone species are nature's influencers. They contribute to ecosystem health through their disproportionate impact on their environments. Through an exploratory sequential …

An investigation of the critical timescales needed for digging in wet and dry soil using a biomimetic burrowing robot
… similar machine. These results suggest that the biomimetic approach successfully used by RoboClam to dig into submerged soil could feasibly be used to dig into dry soil as well.

Two-stage acidic-alkaline pretreatment of Miscanthus for bioethanol production
… acid catalysts included sulfuric acid and two biomimetic acids, trifluoroacetic acid (TFA) and maleic acid (MA), respectively. The influences of acid blending ratio, temperature, and acid dosage on pretreatment performance were investigated. Synergistic effects on hemicellulose decomposition …
