Eremophilane-Type Sesquiterpenes from a Marine-Derived Fungus Penicillium Copticola with Antitumor and Neuroprotective Activities

open access: yesMarine Drugs, 2022
Chemical examination of a marine sponge-associated Penicillium copticola fungus resulted in the isolation of ten undescribed eremophilanes, namely copteremophilanes A–J (1–10), along with two new glycosides, 5-glycopenostatin F (11) and 5-glucopenostatin

Experiment-based kinematic validation of numeric modeling and simulated control of an untethered biomimetic microrobot in channel [PDF]

open access: yes, 2012
Modeling and control of swimming untethered microrobots are important for future therapeutic medical applications. Bio-inspired propulsion methods emerge as realistic substitutes for hydrodynamic thrust generation in micro realm. Accurate modeling, power

Biomimetic modelling [PDF]

open access: yesPhilosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2003
Biomimetics is seen as a path from biology to engineering. The only path from engineering to biology in current use is the application of engineering concepts and models to biological systems. However, there is another pathway: the verification of biological mechanisms by manufacture, leading to an iterative process between biology and engineering in ...

Silver-catalyzed remote Csp3-H functionalization of aliphatic alcohols

open access: yesNature Communications, 2018
Aliphatic alcohols usually require pre-activation for successful functionalization of their carbon chain. Here, the authors report a silver-catalyzed δ-selective functionalization of aliphatic alcohols via Csp3-H bond cleavage under mild conditions ...

Total Synthesis and Structural Revision of the Alkaloid Incargranine B [PDF]

open access: yes, 2013
Seeing double: Consideration of the biosynthetic origins of incargranineB, which was originally assigned an unprecedented indolo[1.7]naphthyridine structure, led to the proposal of a dipyrroloquinoline framework as a more biosynthetically feasible ...

Effect of pH and temperature on the morphology and phases of co-precipitated hydroxyapatite [PDF]

open access: yes, 2012
This paper reports a high-yield process to fabricate biomimetic hydroxyapatite nano-particles or nano-plates. Hydroxyapatite is obtained by simultaneous dripping of calcium chloride and ammonium hydrogen phosphate solutions into a reaction vessel ...

Biomimetics [PDF]

open access: yesCurrent Opinion in Solid State and Materials Science, 2003
The well-organised multifunctional structures, systems and biogenic materials found in nature have attracted the interest of scientists working in many disciplines. The efforts have resulted in the development of a new and rapidly growing field of scientific effort called biomimetics.

Biomimetic buildings [PDF]

open access: yesProceedings of the National Academy of Sciences, 2013
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 …
