Design and Implementation of a Biomimetic Robotic Fish Hongan Wang The study of biomimetic robotic fish has received a growing amount of research interest in the past several years. This thesis describes the development and testing of a novel mechanical design of a biomimetic robotic fish. The robotic fish has a structure which uses oscillating caudal fins and a pair of pectoral fins to generat...

Degradation of hybrid layers created in primary dentin occurs as early as 6 months in vivo. Biomimetic remineralization utilizes "bottom-up" nanotechnology principles for interfibrillar and intrafibrillar remineralization of collagen matrices. This study examined whether imperfect hybrid layers created in primary dentin can be remineralized. Coronal dentin surfaces were prepared from extracted ...

A synthetic water-soluble meso-tetra(2,6-dichloro-3-sulfonatophenyl)porphyrinate of iron(III) chloride, Fe(TDCPPS)Cl, was employed as a biomimetic catalyst in the oxidative coupling of terrestrial humic materials. High-performance size-exclusion chromatography (HPSEC), solid-state nuclear magnetic resonance (CPMAS-(13)C NMR), electron paramagnetic resonance (EPR), and diffuse reflectance infrar...

BACKGROUND Erythrina verna, popularly known as "mulungu", is a Brazilian medicinal plant used to treat anxiety. Erythrina alkaloids have been described in several species of Erythrina, which have biological and therapeutic properties well known that include anxiolytic and sedative effects. METHODS In this work, in vitro metabolism of erythraline (1), the major spirocyclic alkaloid of Erythrin...

The development of functional legged robots has encountered its limits in human-made actuation technology. This paper describes research on the biomimetic design of legs for agile quadrupeds. A biomimetic leg concept that extracts key principles from horse legs which are responsible for the agile and powerful locomotion of these animals is presented. The proposed biomimetic leg model defines th...

Herein, we show that incorporation of ions during biomimetic coating deposition may be utilized to tailor the drug loading capacity of hydroxyapatite (HA) coatings. Pure biomimetic HA (HA-B) and Si-doped equivalents (SiHA-B) where deposited by a biomimetic process onto titanium dioxide covered titanium substrates. The antibiotic Cephalothin was incorporated into the coatings by adsorptive loadi...

Biomimetic Aerogels Inspired by the vessel elements in xylem, water conducting tissue of plants, article 2300370, Peng Cui, Gang Cheng, Zuliang Du, and co-workers synthesize a biomimetic rGO aerogel with aligned porous structures from ice templating for evaporation-induced electricity generation. It can be scaled up used as power source electronic devices.

Life is a specific characteristic of our planet. The diversity of life, biodiversity, is one of the most fascinating phenomena. We know some 1.8 million different species, but all extrapolations show that probably 20 million or more species exist: We know less than 10% of the plants, animals and micro-organisms living on the planet Earth. The editors, who are both biologists, are well acquainte...

The more technology advances, the more there seems to be a basic human yearning to return to nature. This is reflected in a growing number of designers, architects, and artists who are turning to nature’s example to model uses of new technology. San Francisco architect Charles Lee does just that. Lee is a designer, artist, and researcher with the group Bios Design Collective, a group that works...
