Second Law of Thermodynamics May Explain Economic Evolution

Second Law of Thermodynamics May Explain Economic Evolution

first_img Citation: Second Law of Thermodynamics May Explain Economic Evolution (2009, November 2) retrieved 18 August 2019 from https://phys.org/news/2009-11-law-thermodynamics-economic-evolution.html As Annila and Salthe explain in their study published in Entropy, the second law of thermodynamics was originally formulated to describe the flow of heat from hot to cold areas. However, when formulated as an equation of motion, the second law can be used to describe many other processes in energetic terms, such as natural selection for the fittest species, organization of cellular metabolism, or an ecosystem’s food web. In these systems, free energy is consumed; that is, energy is dispersed in a way to promote the maximal increase of entropy, which is the essence of the second law.While economic activities are traditionally viewed as being motivated by profit, Annila and Salthe argue that the ultimate motivation of economic activities is not to maximize profit or productivity, but rather to disperse energy. From this perspective, a growing economy consists of entities (e.g. products, labor, etc.) that are assigned an energy density resulting from their individual production processes. These density differences are the forces that direct energy flows (e.g. manufacturing processes) to equalize energy density differences within the system and with respect to its surroundings. The scientists argue that this tendency to disperse the maximum amount of energy (that is, to consume free energy in the least time) is what gives rise to economic laws and regularities. Further, economies organize themselves in hierarchical systems within systems to improve on energy dispersal and to access new sources of energy. For instance, the global economy is comprised of national economies, each housing economic zones that in turn accommodate districts, firms, households and so on, organized so that global resources are produced and consumed most effectively in terms of energy dispersal. From this thermodynamic perspective, decision making is ultimately about choosing the action that causes energy to flow along the most steeply descending energy gradient. For example, when faced with two identical products where one is cheaper than the other, a consumer will likely choose the cheaper product.

Explore furthercenter_img (PhysOrg.com) — Terms such as the “invisible hand,” laissez-faire policy, and free-market principles suggest that economic growth and decline in capitalist societies seem to be somehow self-regulated. Now, scientists Arto Annila of the University of Helsinki and Stanley Salthe of Binghampton University in New York show that economic activity can be regarded as an evolutionary process governed by the second law of thermodynamics. Their perspective may provide insight into some fundamental economic questions, such as the causes of economic growth and diversification, as well as why it’s so difficult to predict economic growth and decline. “When investing on the cheaper but equally good product, more energy (in one’s assets) is left to be dispersed by buying other goods,” Annila explained to PhysOrg.com. “Also, when the cheaper product sells better, the energy used in its production gets consumed faster.”However, decision-making is not always this straightforward because consumers, producers, and other players in the market make decisions based on their subjective views of energy gradients, which are affected by diverse and often conflicting factors. Each player in the market may prefer a particular series of actions (their strategy) to move from one state to another that is higher in entropy production. When the circumstances change, for example due to other players’ actions, a player may revise their strategy in the quest to optimally consume free energy. As the scientists explain, it’s inherently impossible to predict future economic growth and decline in any detail from this perspective. The fundamental reason for this unpredictability is that the economy’s energy density is not constant, so that a player’s decision will affect future decisions that are open for other players. Physically speaking, the forces (free energy in resources) that drive the flows (economic activities) are in turn affected by the flows and so on. Moreover, each player tries to take into account how their decision will affect the decisions made by others. The result of these complex interactions based on subjective decision-making means that economies with highly effective mechanisms of energy dispersal, such as the stock exchange and the market of raw materials, may change very rapidly and unexpectedly. “The second law encourages activities that consume free energy as soon as possible,” Annila said. “Therefore, there is the quest to increase productivity and throughput and to find new sources of energy. Moreover, the second law reveals that it is impossible to predict in detail the optimal course of energy utilization because the chosen course itself affects the choice for future actions. Therefore, it makes sense to favor statistically independent actions that open new opportunities to consume free energy, and likewise to regard the use of insider information as illegal since it narrows the choices.”More information: Arto Annila and Stanley Salthe. “Economies Evolve by Energy Dispersal.” Entropy, 2009, 11, 606-633; doi:10.3390/e11040606Copyright 2009 PhysOrg.com.

The compressible region is made from silicone cast in 3D printed molds. Credit: Walters, et al. Centre for Fine Print Research and Bristol Robotics Laboratory ©2013 IOP Publishing Ltd In the new paper, the researchers’ goal was to investigate the potential to replace the motor-driven pump with a biologically inspired pump made of “smart” materials that move more like muscles than like motors. To do this, they modeled their pump on the human heart and built it with compressible materials, NiTi fibers as artificial muscles, rubber balls as artificial heart valves, and silicone tubes as artificial arteries. The rigid parts of the body of the pump were fabricated by a 3D printer, while the soft compressible section was cast in silicone using 3D printed moulds. © 2013 Phys.org. All rights reserved. (Phys.org) —It’s a first: researchers have built the first artificial-heart-like pump that is powered by microbial fuel cells fed on human urine. But instead of being used as a prosthetic device for human patients suffering from cardiac failure, the pump is intended to be used in “EcoBots” that extract energy from organic waste and turn it into electricity. Explore further The pump operates very similarly to a human heart. Before starting, the hollow body of the actuator is manually filled with fluid—in this case, the researchers used water or urine. Then an electric current is applied to the NiTi artificial muscle fibers. The current heats the fibers and causes them to contract, which compresses the hollow body of the actuator and pushes the fluid out through an outlet tube. When the electric current is removed, the artificial muscles cool and relax, causing the body to expand again. As this cycle repeats, it simulates the rhythmic contractions of a biological heart. During each contraction, or actuation, fluid is pumped out of the actuator at a height that would be sufficient to deliver fuel to an EcoBot’s fuel cells. The researchers calculated the efficiency of the heart-like pump to be 0.11%, which is significantly lower than the 0.79% efficiency of an electric motor-driven pump. However, as the researchers noted, motor-driven pumps have been developed and refined over several decades, while this actuator is the first proof-of-concept prototype of its kind. In the short term, the researchers expect that further improvements can be made in a few ways, such as by minimizing hydrodynamic losses due to friction, creating a smoother transition between the pump body and outlet port, and decreasing the weight of the hollow body by reducing the wall thickness. In the longer term, it is expected that the efficiency of artificial muscle materials may improve. The researchers also demonstrated the potential for this heart-like pump to be used to circulate fluid for the MFCs on a future MFC-powered EcoBot. In such a system, a stack of 24 MFCs would charge a capacitor which powers the pump which is then used to pump fluid through the MFCs. After an initial charging period of 12 hours, the capacitor provides enough energy for the pump to transfer 27 ml of fluid, and can then be recharged in about 2.5 hours. Even though it is the first prototype, this system meets the current EcoBot’s daily fluid pumping requirements. And because the internal orifices of the heart-like pump are larger than in the conventional electric-motor driven pumps employed previously on the EcoBot, the researchers hope that it will be less likely to become blocked. The researchers envision a future urine-powered EcoBot that harvests energy from waste collected from urinals at public lavatories, and then uses the harvested energy for environmental sensing. A number of EcoBots could form a distributed sensor network within an urban area.The heart-like pump also has the potential to be used for a variety of industrial, scientific and medical applications, such as coolant circulation or wearable drug delivery. The soft pump has the advantage of operating with much less noise than a motor-driven pump, which could give it certain niche applications.And because the EcoBot’s ability to turn waste into electricity is such a captivating concept, the researchers think that the artificial heart-like pump could help increase public awareness of research in biologically inspired robots. They imagine, for instance, that a cyborg-like machine with an artificial heartbeat would attract the interest of a new generation of scientists, artists, and engineers. The researchers are also working on improving the efficiency of the device, with the aim of incorporating it into the next generation of MFC-powered robots.

Centre for Fine Print Research and Bristol Robotics Laboratory ©2013 IOP Publishing Ltd The researchers, from the University of the West of England and the University of Bristol, both in Bristol, UK, have published their paper on the biologically inspired, urine-powered pump in a recent issue of Bioinspiration & Biomimetics. The group’s research into microbial fuel cells fed on urine is one of the many diverse projects receiving funding from the Bill and Melinda Gates Foundation.The researchers have already designed and fabricated several varieties of EcoBots. These robots are energetically autonomous, meaning they generate their own energy, in this case using onboard microbial fuel cells (MFCs). In the MFCs, live microbes digest organic feedstock and then produce electrons that are transferred to an electrode, causing a chemical reaction that generates electrical energy. The EcoBots have demonstrated that they can successfully use a variety of organic feedstocks such as rotten fruits and vegetables, dead flies, waste water, sewage sludge, and human urine. The energy produced by the EcoBots from this waste could then be used for low-energy environmental sensing tasks, such as monitoring air quality and pollution levels. A vital component of the EcoBot design is a pump that delivers the liquid organic feedstock to the chambers in the MFCs containing the microbes and electrodes. The pump also supplies fresh water to hydrate the electrodes. In the EcoBots built so far, electric motor-driven pumps have been used for fluid circulation. However, electric motor-driven pumps are complex and prone to mechanical failure. This document is subject to copyright.

Golden silver nanoparticle looks and behaves like gold

Golden silver nanoparticle looks and behaves like gold

DOI: 10.1021/jacs.5b07088 Journal information: Journal of the American Chemical Society The ‘golden’ silver nanocluster with 25 silver atoms and 18 ligand molecules, (left) without a counterion and (right) with a counterion. The structures show silver atoms on the vertices of the icosahedron (green), silver atoms on the icosahedron faces (purple), sulfur atoms (yellow), carbon atoms (gray), and phosphorus atoms (red). Credit: Osman Bakr, KAUST Separate teams develop similar method for creating non-oxidizing silver nanoparticles The scientists investigated the silver nanocluster’s crystal structure using X-ray diffraction, in which an X-ray beam strikes the crystallized structure and is reflected at various angles to create a diffraction pattern on a detector. This technique revealed that the silver nanocluster has one silver atom at the center of a 12-pointed-star-like shape called an icosahedron. While 12 of the other silver atoms form the 12 points, the remaining 12 silver atoms occupy some of the faces. This arrangement is almost exactly like that of the gold nanocluster, except that three of the atoms on the faces of the silver nanocluster are turned in a different direction. As far as the scientists can tell, the orientation of these three atoms is the only notable structural difference between the silver and gold nanoclusters, and it causes a slight distortion in the silver nanoclusters. (Phys.org)—In an act of “nano-alchemy,” scientists have synthesized a silver (Ag) nanocluster that is virtually identical to a gold (Au) nanocluster. On the outside, the silver nanocluster has a golden yellow color, and on the inside, its chemical structure and properties also closely mimic those of its gold counterpart. The work shows that it may be possible to create silver nanoparticles that look and behave like gold despite underlying differences between the two elements, and could lead to creating similar analogues between other pairs of elements. Citation: ‘Golden’ silver nanoparticle looks and behaves like gold (2015, September 22) retrieved 18 August 2019 from https://phys.org/news/2015-09-golden-silver-nanoparticle-gold.html The researchers, led by Osman Bakr, Associate Professor of Materials Science and Engineering at King Abdullah University of Science and Technology (KAUST) in Saudi Arabia, have published the paper in a recent issue of the Journal of the American Chemical Society.”In some aspects, this is very similar to alchemy, but we call it ‘nano-alchemy,'” Bakr told Phys.org. “When we first encountered the optical spectrum of the silver nanocluster, we thought that we may have inadvertently switched the chemical reagents for silver with gold, and ended up with gold nanoparticles instead. But repeated synthesis and measurements proved that the clusters were indeed silver and yet show properties akin to gold. It was really surprising to us as scientists to find not only similarities in the color and optical properties, but also the X-ray structure.”Like all chemical elements, silver and gold are defined by their number of protons: silver has 47, and gold has 79. The work here doesn’t change the number of protons in an atom of silver; otherwise it would no longer be considered silver. Instead, the researchers synthesized a nanocluster of 25 silver atoms, along with 18 other molecules called “ligands” that surround the silver atoms. The entire negatively charged, silver-based complex ion has the chemical formula [Ag25(SPhMe2)18]-.Although a few other silver nanoclusters have been synthesized in recent years, this is the first silver nanocluster that has a matching analogue in gold: [Au25(SPhMe2)18]- has previously been reported. Besides both nanoclusters having 25 metal atoms and 18 ligands, they also both have all of their atoms and electrons arranged in almost exactly the same way. In their study, the researchers performed tests demonstrating that the silver and gold nanoclusters have very similar optical properties. Typically, silver nanoclusters are brown or red in color, but this one looks just like gold because it emits light at almost the same wavelength (around 675 nm) as gold. The golden color can be explained by the fact that both nanoclusters have virtually identical crystal structures. The question naturally arises: why are these silver and gold nanoclusters so similar, when individual atoms of silver and gold are very different, in terms of their optical and structural properties? As Bakr explained, the answer may have to do with the fact that, although larger in size, the nanoclusters behave like “superatoms” in the sense that their electrons orbit the entire nanocluster as if it were a single giant atom. These superatomic orbitals in the silver and gold nanoclusters are very similar, and, in general, an atom’s electron configuration contributes significantly to its properties.”The size scale of nanoparticles lies in between atoms/molecules and bulk material, where the absolute rule of neither quantum nor classical physics is observed,” Bakr explained. “However, the Ag nanoparticle we synthesized was so small in size that it actually behaves a lot like an atom, i.e., a superatom. Since the structural framework of Ag25 is nearly identical to Au25, which makes similar atomic arrangements in 3D space, this special atomic arrangement allows for the hybridization of Ag atomic orbitals and ligand orbitals (the organic molecules surrounding the metal) in Ag25 to produce superatomic orbitals that are very similar to the well-known Au25 system. This could be the main reason for the similarities observed between the Ag and Au clusters, which may not be possible to achieve with individual atoms or bulk materials.”While the results here show that silver can acquire the properties of gold, the reverse may also be possible, with gold being synthesized to look and behave like silver. “If silver can acquire properties of gold, there is no obvious reason why the reverse shouldn’t be possible,” Bakr said.This duality, in which one type of atom acquires the properties of another, has the potential to offer unprecedented abilities in nanoscience research, and is one area that the scientists plan to investigate more in the future.The researchers also hope that the results will lead to a better understanding of the fundamental differences between gold and silver. For instance, although both materials are lustrous metals, gold is relatively biocompatible and being researched for biomedicine, whereas silver is cytotoxic and used in antibacterial surface coatings. Questions like these may be answered by blurring the lines between the elements as we know them.”Our future plan is to synthesize other sizes of gold clusters and other metal analogues of gold nanoparticles to explore whether these clusters would still show the behavior of gold or not,” Bakr said. “Our goal is to find cheaper substitutes for gold in applications where gold nanoparticles are required.” (Left) Optical properties of the silver and gold nanoclusters, with the inset showing photographs of the actual color of the synthesized nanoclusters.

The domains here correspond to different superfluid phases (B+ and B−), which are separated by nonsuperfluid domain walls (blue). Credit: APS/Alan Stonebraker Journal information: Physical Review Letters A lot of work over the past several years has shown that superconductivity is quite common in metals subjected to very cold temperatures. Scientists have found that the zero-resistance state arises due to electrons forming a condensate of Cooper pairs that carry electrical current without losing any of it. Less well known is that similar pairings happen in neutron stars, quark matter, some gases at very low temperatures and neutral helium-3 atoms. In this new effort, the researchers were studying the behavior of such atoms under varying conditions, and in so doing, discovered that a 2-D pattern appeared in superfluid helium-3 when it was confined using a magnetic field.In their work, the researchers pumped helium-3 into a silicon-glass cell with an inner cavity that had a height of just 1.1um—they increased the pressure inside to 30 mbar. Next, they took pulsed nuclear magnetic resonance measurements in an applied magnetic field of 31 mT. They report that doing so allowed them to identify two B phases in the cavity. They note that they were expecting to see single-dimensional modulation in both B+ and B- phases, and stripes would form with walls between them made of non-superfluid material. Instead, they found that the area of the B+ domain was four times bigger than the B- domain. They noted that this meant that their stripe assumptions were incorrect. To explain the difference, they suggest a 2-D modulation in superfluid order in which the B-domains are patterned like polka-dots within a B+ domain. The researchers note that their findings open the door to more questions, such as the size of the polka-dots and the distance between them. Additionally, the nature of the boundaries is unknown as yet. Because the pattern was unexpected, new theories are required to explain it. This document is subject to copyright.
