Quantum biomimetics consists of reproducing in quantum systems certain properties exclusive to living organisms. Researchers at University of the Basque Country have imitated natural selection, learning and memory in a new study. The mechanisms developed could give quantum computation a boost and facilitate the learning process in machines. [14] A Chinese team of physicists have trained a quantum computer to recognise handwritten characters, the first demonstration of quantum artificial intelligence . Physicists have long claimed that quantum computers have the potential to dramatically outperform the most powerful conventional processors. The secret sauce at work here is the strange quantum phenomenon of superposition, where a quantum object can exist in two states at the same time. [13] One of biologys biggest mysteries-how a sliced up flatworm can regenerate into new organisms-has been solved independently by a computer. The discovery marks the first time that a computer has come up with ...

The catalytic activity of highvalent iron-oxo active species of heme enzymes is known to be dependent on the nature of the axial ligand trans to the iron-oxo group. In a similar fashion, experimental studies on iron-oxo porphyrin biomimetic systems have shown a significant axial ligand effect on ethylbenzene hydroxylation, with an axial acetonitrile ligand leading to phenyl hydroxylation products and an axial chloride anion giving predominantly benzyl hydroxylation products. To elucidate the fundamental factors that distinguish this regioselectivity reversal in iron-oxo porphyrin catalysis, we have performed a series of density functional theory calculations on the hydroxylation of ethylbenzene by [FeIV=O(Por+)L] (Por = porphyrin; L = NCCH3 or Cl-), which affords 1-phenylethanol and p-ethylphenol products. The calculations confirm the experimentally determined product distributions. Furthermore, a detailed analysis of the electronic differences between the two oxidants shows that their reversed ...

Nacre exhibits similar mechanical properties however with rather simpler structure. Nacre shows a brick and mortar llike structure with thick mineral layer (0.2∼0.9-μm) of closely packed aragonite structures and thin organic matrix (∼20-nm).[27] While thin films and micrometer sized samples that mimic these structures are already produced, successful production of bulk biomimetic structural materials is yet to be realized. However, numerous processing techniques have been proposed for producing nacre like materials.[25]. Biomorphic mineralization is a technique that produces materials with morphologies and structures resembling those of natural living organisms by using bio-structures as templates for mineralization. Compared to other methods of material production, biomorphic mineralization is facile, environmentally benign and economic.[28]. Freeze casting (Ice templating), an inexpensive method to mimic natural layered structures was employed by researchers at Lawrence Berkeley National ...
Despite huge efforts, tissue engineers and orthopedic surgeons still face a great challenge to functionally repair osteochondral (OC) defects. Nevertheless, over the past decade great progress has been made to find a suitable strategy towards OC regeneration. In the clinics, some osteochondral tissue engineering (OCTE) approaches have already been applied although with some incongruous outcomes as OC tissue is complex in its architecture and function. In this chapter, we summarize current OCTE strategies that are focused on hierarchical scaffold design, mainly layered scaffolds. Most suitable candidates towards functional regeneration of OC tissues are envisaged from monophasic to the layered scaffolds. Herein is documented a variety of approaches with their intrinsic properties applied as bare scaffolds or in combination with biologics, either in in vitro or in vivo evaluations aiming at functional OC regeneration. The most noteworthy studies in OC regeneration developed within the past 5 years ...

Recent theoretical and technological advances have spurred a broad interest to develop practical multirobot systems [1]-[5]. For mobile robots, navigation skill is one of their fundamental capabilities. Different navigation strategies are appropriate for different contexts. Different sensor types and sensing modules are used depending on the application scenarios. However, a problem of common interests and practical significance is how to perform tasks with less information and simpler sensors, such as using binary sensors, or using bearing-only or range-only sensors. This problem has attracted much attention in the multirobot community because an advantage of cooperation of teams of robots is that simple agents are able to perform complex tasks through mutual cooperation.. Bearing-only-based navigation is an approach to simplify the sensing system and is very useful in some cases. For example, for mobile robots equipped with single omnidirectional camera, or radar and sonar operating in passive ...

For the second experiment, the aim was to ascertain how efficient in terms of number of training samples the learning process was, with multi-modal representations, in comparison with each individual modality. The reasoning is that it may be considered unfair to compare a vision-only system which used 60 training samples against a visuo-tactile system that used 120 (60 visual and 60 touch). Instead, the total number of training samples was set to a fixed value and the accuracy for uni-modal and multi-modal was computed. For example, when the number of training samples was set to 40, tactile-only and visual-only recognition was performed using 40 training samples, but multi-modal recognition was performed using 20 visual and 20 tactile, or 35 visual and 5 tactile, or any other combination. This is different to all previous work encountered, where, when it comes to sensor fusion, all data from both modalities are typically used (such as in the first experiment).. At test time, a single image was ...

A biomimetic approach was taken for studying the adsorption of a model copolymer (pullulan abietate, DS 0.027), representing the lignin-carbohydrate complex, to a model surface for cellulose fibers (Langmuir-Blodgett thin films of regenerated cellulose). Adsorption results were assayed using surface plasmon resonance spectroscopy (SPR) and atomic force microscopy (AFM). Rapid, spontaneous, and desorption-resistant surface modification resulted. This effort is viewed as a critical first step towards the permanent surface modification of cellulose fibers with a layer of molecules amenable to either enzymatic crosslinking for improved wood composites or thermoplastic consolidation.

In early 1980s, researchers discovered self-setting calcium orthophosphate cements, which are bioactive and biodegradable grafting bioceramics in the form of a powder and a liquid. After mixing, both phases form pastes, which set and harden forming either a non-stoichiometric calcium deficient hydroxyapatite or brushite. Since both of them are remarkably biocompartible, bioresorbable and osteoconductive, self-setting calcium orthophosphate formulations appear to be promising bioceramics for bone grafting. Furthermore, such formulations possess excellent molding capabilities, easy manipulation and nearly perfect adaptation to the complex shapes of bone defects, followed by gradual bioresorption and new bone formation. In addition, reinforced formulations have been introduced, which might be described as calcium orthophosphate concretes. The discovery of self-setting properties opened up a new era in the medical application of calcium orthophosphates and many commercial trademarks have been introduced as

Fresh water scarcity is one of the problems that the whole world is facing today. Forward osmosis and low pressure reverse osmosis are possible solutions to provide high quality water. Thus, creating a robust and highly permeable yet selective membrane for water purification has gained much attention worldwide in recent years. This thesis presents a systematic study on the design and fabrication of AquaporinZ (AqpZ)-embedded biomimetic membrane. Firstly, the mechanical property of the artificial AqpZ-embedded lipid bilayer membrane was explored. Secondly, the performance of biomimetic membrane has been has been demonstrated in forward osmosis. Thirdly, a new membrane with enhanced the mechanical property and higher permeability and selectivity has been fabricated. Finally, water transport through the robust AqpZ-embedded vesicular membrane has been investigated through a newly modified transport model in a FO process. This study provides a direction for the further development of the ...
Imagine 3.8 billion years of slow but steady research and development (otherwise known as evolution), covering everything we need to survive and thrive here on Earth, freely available for everyone. You just need to know where and (more importantly) how to look for it, because the evidence of this massive R+D effort is everywhere. The study and exploitation of naturally evolved solutions for engineering systems is variously known as bionics, biomimetics, biomimicry, biognosis, bionical creativity engineering, bioinspired engineering, and maybe others. While theres no single agreed name, there is consensus on the fact that nature is a great source for engineering inspiration.. ...
The advisory board members of the Metaphor Lab each write a short blog about their current research on metaphor.. This time, Chiua Xu writes about the argumentative function of metaphor in argumentation.. Metaphor is often used in daily communication. A number of studies focus on how metaphor may enhance the persuasive power of discourse (e.g. Cameron & Deignan, 2006; Charteris-Black, 2011; Hauser & Schwarz, 2014). But since these studies approach to metaphor from a purely rhetorical perspective, the question as to how metaphor is used in argumentation remains unanswered. In our research, we study metaphor from the perspective of a rational discussion, focusing on questions such as: What representations do metaphors have in argumentation? How do metaphorical expressions function in different types of arguments? In this blog, I discuss three projects that focus on these issues.. Read the blog here.. ...

Our goal is to use biomimetics to develop an uncooled, photomechanic infrared sensor. Our design is inspired by the pyrophilous beetle Melanophila acuminata, which employs photomechanical-based IR sensor organs and is extremely sensitive to the 3 m band (to detect forest fires) with possible sensitivity to the 9 m band as well (to evade capture by predators). IR sensors based on the photomechanical-effect may well provide an efficient and highly sensitive means for various civilian, military and industry applications such as the detection of forest fires, pedestrian and infantry detection and medical thermography. We are engineering MEMS devices based on the photomechanical IR organs of the jewel beetle to transduce changes in IR for use in an electromechanical IR imaging system. These sensors will have a performance equal to or exceeding a standardized detectivity (D*) of 1e8 cm*sqrt(Hz)/W, NEDT equal or less than 20 mK, pixel size equal or less than 20 m and field of view equal or greater than ...

This biomimetic ligand, N-[2-(1 H-imidazol-4yl)-ethyl]-2-(1[2-(1H-imidazol-4-yl)-ethylcarbamoyl]-methyl)-amino)-acetamide, has been also grafted on silica surface via covalent bond. The supported and non-supported biomimetics reacted with manganese(II) ions leading to the formation of the corresponding metal complexes. These have been evaluated as catalysts for alkene epoxidation with H2O2 in the presence of ammonium acetate as an additive. Our data showed that the homogeneous and the supported systems are able to overcome the competitive H2O2 dismutation, by the use of only two times H2O2 with respect to substrate, favouring productive alkene epoxiclations to a significant extent.

The rational synthesis of meso-aryl substituted porphyrins and related macrocycles were investigated and their chelation behavior studied. ^ 1. meso-Tetraarylporphyrins are one of the most studied synthetic porphyrins because of their various potential applications in medicinal and materials chemistry and biomimetics. The less studied 5,15-diphenylporphyrin (5,15-DPP) has found applications, for instance, in multi-porphyrin assemblies. The equally interesting and potentially useful cis-isomer to 5,15-DPP, 5,10-diphenylporphyrin (5,10-DPP) has not been described in the literature before. We have utilized the 2 + 2 methodology (condensation of two dipyrrolic units) to synthesize the novel compound 5,10-DPP. ^ 2. meso-Triarylcorroles have become known only recently as the serendipitous side products of a pyrrole-benzaldehyde condensation reaction. We developed a rational, stepwise synthetic methodology to prepare meso-triarylcorroles. The key step in this method is the preparation of a
The spider silk project is just one example of biomimetics, the study of biological materials, processes, and structures in order to imitate or improve them. Modern analytical instruments and bioengineering techniques are expanding our ability to duplicate nature. The hinge of a flys wing has to be very flexible and springy in order to move back and forth hundreds of times each second. It is made of a material called resilin, which has been described as the most perfect rubber ever found. Barnacles attach themselves to ships and whales with a glue so strong they are almost impossible to remove. Determining the chemical composition and structure of fly resilin and barnacle glue may make it possible for us to produce better rubber and adhesives.. In addition to studying the chemical structure and composition of natural materials, biomimeticists study how nature puts those materials together. A spiders web is a remarkable engineering achievement. Using a very small amount of material, the spider ...

At the University I enjoy seeing the developments that come out of the Auckland Biomimetics Lab, hosted in the Auckland Bioengineering Institute, and run by Associate Professor Iain Anderson. The work done in the lab involves. drawing inspiration from nature to develop new technologies. Living organisms and natural phenomena have certain behaviours and properties which let them exist in harmony with the surrounding environment. By understanding these natural processes, we are developing technologies to venture into new territories.. One of the labs projects is building a human powered racing submarine (known as Project Taniwha) which they race in an international contest each year. This year the team won the overall trophy, as well as awards for being the most reliable submarine and the best non-propeller powered submarine. The team are the only Southern Hemisphere team.

Increased emphasis is being placed on the importance of conserving sound tooth structure during restorative procedures. Whether for the replacement of worn or discolored restorations, or for the correction of unesthetic form or malalignment, treatments are now guided by principles of minimal intervention and biomodification.1-3 Specifically, todays forward-thinking clinicians are being called to embrace minimally invasive techniques when providing patients with necessary and/or elective dental treatments.. It is therefore incumbent upon clinicians to consider treatment alternatives critically, so that the outcomes of these efforts can be as esthetic, durable, and predictable as possible. Fortunately, todays clinicians are practicing in an era when biomodification and biomimetics are driving product developments, and the consequence is that treatments can be applied in less technique-sensitive manners to answer clinical challenges in naturally esthetic and functional ways.4. The rationale ...
Scientists at University of Oxford have developed a bio-inspired superglue. According to an article by Jonathan Wood, at University of Oxford, the Oxford researchers developed the bio-superglue by engineering an unusual protein from a type of bacteria that can cause life-threatening disease (Streptococcus pyogenes).. The scientists think the new Molecular Super Glue will be very useful in the biotechnology and nanotechnology fields. Previously scientists had trouble getting a strong grip when trying to work with proteins, but this new substance will grab hold of proteins or stick them immovably to surfaces. Dr. Mark Howarth and his graduate student Bijan Zakeri at the Department of Biochemistry are conducting the study using funding from the Clarendon Fund at Oxford. The author in his article states:. The protein FbaB from Streptococcus pyogenes has a 3D structure that is stabilised by another covalent bond. This strong chemical bond forms in an instant and binds the loops of the amino ...

M.V. Lomonosov Moscow State University Doctor of Science 1983 Physics & Mathematics. Personal Statement:. Professor Alexei R. Khokhlov is an internationally recognized scientist known for his outstanding contributions to various branches of polymer science. In 1976, while he still was an undergraduate student, he proposed, together with I.M.Lifshitz and A.Yu.Grosberg, the theory of coil-globule transitions in linear macromolecules. Later, A.R.Khokhlov developed this theory for the analysis of a wide variety of phenomena in polymer science: collapse of gels, of polyelectrolyte macromolecules, compactization of DNA molecules etc. In 1979-1988, together with A.N.Semenov, Professor Khokhlov performed pioneering studies in the field of liquid-crystalline polymers. As a result, the theory of liquid-crystalline ordering in the solutions of stiff-chain macromolecules with partial flexibility was first developed. In 1998 Professor Khokhlov proposed an original biomimetic approach aimed to the synthesis ...
Cradle-to-cradle design (also referred to as Cradle to Cradle, C2C, cradle 2 cradle, or regenerative design) is a biomimetic approach to the design of products and systems that models human industry on natures processes viewing materials as nutrients circulating in healthy, safe metabolisms. The term itself is a play on the popular corporate phrase Cradle to Grave, implying that the C2C model is sustainable and considerate of life and future generations (i.e. from the birth, or cradle, of one generation to the next versus from birth to death, or grave, within the same generation.) C2C suggests that industry must protect and enrich ecosystems and natures biological metabolism while also maintaining a safe, productive technical metabolism for the high-quality use and circulation of organic and technical nutrients.[1] It is a holistic, economic, industrial and social framework that seeks to create systems that are not only efficient but also essentially waste free.[2] The model in its ...
The development of efficient catalyst for water oxidation is of paramount importance to artificial photosynthesis, but before this can be achieved a deeper understanding of this reaction is essential. In nature this reaction occurs in a tetranuclear Mn-cluster which serves as the work-horse of oxygenic photosynthesis. This thesis summarises my efforts at developing molecular systems capable of mimicking this complex employing a biomimetic approach.. Three different approaches towards this goal are described here-in. The first section describes a screening study, in which a number of manganese complexes were tested to see whether or not they were capable of catalysing the formation of dioxygen when treated with different oxidants (Papers I). For those reactions in which dioxygen formation was observed the reactions were repeated in labelled water and the incorporation of labelled O-atoms was studied by mass spectrometry. This allowed us to determine to what extent water was the source of the ...
Its sad when you realize that its mostly the common people who actually work & reside outside of mainstream Academia & the Scientific community who are the ones who have to pushed for a more biomimetic approach to caring for this planet. Spencer Smith is one of those as are Joel Salatin and Gabe Brown. But there are also many well known institutions who have taken the bold step of rejecting mainstream science-based methodologies with regards the usage of synthetic fertilizers, herbicides, insecticides and fungicides. Unfortunately for all of us, theirs is not the science that rules our world. At times many of these people who have chosen to pursue a course of holistic biomimicry have been criticized for their supposedly pseudoscientific course of action by the Scientific Orthodoxy of Academics who have prior industrial commitments. Nothing about biomimicry is anti-science, rather the so-called Green Revolution we have all been force fed since Elementary School is just plain bad science ...
Definition and function Comprehended more as an easy way of examining an investigation issue compared to a methodological design, philosophical analysis and argumentation is supposed to challenge profoundly embedded, usually intractable, presumptions underpinning a location of research. This process utilizes the equipment of argumentation produced from philosophical traditions, ideas, models, and theories to critically explore and challenge, as an example, the relevance of logic and proof in educational debates, to investigate arguments about fundamental dilemmas, or even to talk about the cause of current discourse about an investigation issue. These overarching tools of analysis may be framed in 3 ways:. ...
I wonder if there isnt a confirmation bias here. Consider all the ideas about evolutionary process first promulgated verbally that turned out to be crap. Orthogenesis. Recapitulation. Naive group selectionism. Saltationism. Polygenism.. I wont count use inheritance, because it actually is described well mathematically and may work for cultural evolution. Evolutionary biology has a lot of recycling of common-sensical insights, and a lot of new rediscoveries of what Darwin said 150 years ago. This is all because of the propensity for verbal argumentation. A more subtle problem is that words change their meanings. Fitness, mentioned in the previous comment is a good example. I think Dobzhansky did better at verbal argumentation than almost anyone, but it is fairly easy to put words into even his mouth. Dawkins did a masterful job of putting Williams and Hamilton into English, but hardened them in the process. When you consider Goulds big volume, or Mayrs History of Biological Thought, they ...
Madam, - I was disturbed to read in Thursdays Irish Times yet another factually inaccurate opinion piece from one of the small band of eco-loonies. The idea that the climate is paying the price for low-cost flying is as absurd as it is untrue.. In an article littered with false claims and environmental mumbo-jumbo, readers are invited to share the writers delusion that massive increases in taxation (on air travel) will somehow save our planet, as if it needs saving in the first place. Wrong, wrong and wrong again.. Instead of this eco-babble, perhaps your readers would be interested in some actual facts:. 1. The European Environmental Agency confirms that aviation accounts for less than 2 per cent of Europes CO2 emissions. By contrast, shipping accounts for 5 per cent, motor transport 18 per cent and power generation (mainly Government-owned) some 26 per cent.. 2. No industry has improved its technology usage or reduced its emissions per customer as much as the airline industry in the ...
RGD-conjugated Tetronic-tyramine (RGD-Tet-TA) hydrogels were formed in situ, and cell attachment and spreading on the hydrogels were evaluated for an injectable tissue-regenerative scaffold. The hydrogels were prepared by simple mixing GRGDGGGGGY (RGD-Y) in a tyramine-conjugated Tetronic (Tet-TA) polymer sol
Molecular machines are an important and emerging frontier in research encompassing interdisciplinary subjects of chemistry, physics, biology, and nanotechnology. Although there has been major interest in creating synthetic molecular machines, research on natural molecular machines is also crucial. Biomolecular motors are natural molecular machines existing in nearly every living systems. They play a vital role in almost every essential process ranging from intracellular transport to cell division, muscle contraction and the biosynthesis of ATP that fuels life processes. The construction of biomolecular motor-based biomimetic systems can help not only to deeply understand the mechanisms of motor proteins in the biological process but also to push forward the development of bionics and biomolecular motor-based devices or nanomachines. From combination of natural biomolecular motors with supramolecular chemistry, great opportunities could emerge toward the development of intelligent molecular ...
In this Masters research project, you will explore the possibilities of circumventing these challenges by developing a novel technique to apply known, cell-like forces at cell-like (micrometer) length scale. The technique will involve innovative light-induced smart material that can deform on cue. Moreover, you will investigate how these cell-like forces are transmitted to the environment. When the technique is optimized, you will investigate how living cells respond to forces produced by these cell-like particles. This project is a collaboration between groups in the Department of Biomedical Engineering and the Department of Chemistry and is suited for students interested in smart biomimetic systems, image analysis, and cell-matrix interactions.
One new trend in lignin research is to steer biosynthetic pathways toward the biosynthesis of molecules that, upon incorporation into the lignin polymer, will improve lignin degradation. This idea stems from the growing list of newly discovered lignin monomers, from the observation that lignin is able to readily copolymerize alternative units that derive from incomplete monolignol biosynthesis in plants with pathway perturbations, and from examples in which plants with altered lignin structures are shown to be viable and more easily processed (Pilate et al., 2002; Huntley et al., 2003; Ralph et al., 2006; Leplé et al., 2007). This concept of copolymerizing alternative lignin monomers into the polymer has already been demonstrated in a biomimetic system by polymerizing coniferyl ferulate together with normal monolignols into maize primary cell walls (Grabber et al., 2008). The resulting lignin, now strongly enriched in easily breakable ester bonds in the lignin backbone, degrades at lower ...
Photoinduced biological processes are complex and can often be reduced to a series of sequential events after the absorption of the photon. Each of these steps, if separable, can be compared with the evolution of a much simpler system, mimicking its essential characteristics, a biomimetic system. This stems from the very local properties of the initial event where a small reaction centre has been excited, spatially limited within the biomolecule. Gas phase conditions provide the unique way to study these model systems.

N2 - Using natural photosynthesis as a model, bio-inspired constructs for fuel generation from sunlight are being developed. Here we report the synthesis and time-resolved spectroscopic analysis of a molecular triad in which a porphyrin electron donor is covalently linked to both a cyanoporphyrin electron acceptor and a benzimidazole-phenol model for the TyrZ-D1His190 pair of PSII. A dual-laser setup enabled us to record the ultrafast kinetics and long-living species in a single experiment. From this data, the photophysical relaxation pathways were elucidated for the triad and reference compounds. For the triad, quenching of the cyanoporphyrin singlet ...
