IBM started the Battery 500 Project in 2009 to develop a lithium-air battery that could power an electric car for 500 miles. Lithium-air batteries have a much higher energy density than lithium-ion batteries, theoretically allowing an electric car to travel much farther on a single charge. However, earlier versions of lithium-air batteries were unstable and their lifetime was reduced after frequent recharging. IBM researchers have now developed an alternative electrolyte material that could stabilize the chemical reactions and allow for a working lithium-air battery prototype by 2013 and commercial batteries by 2020.

Firefly batteries can provide similar performance to advanced battery technologies like lithium-ion, but at a much lower cost similar to lead-acid batteries.
Facility Scale Battery Storage
Demand response programs across the country have many large facilities considering the deployment of energy storage technologies. Technologies developed for facility- and campus-scale energy storage show promise for managing short-term demand peaks as well as longer-period demand response events.
The presenter has investigated facility/campus-scale energy storage for efficiency program administrators in the US and recently completed a storage technology research report for an international consortium of utilities. This work has identified promising avenues for distributed storage. Currently, facility-scale storage has three primary uses: 1. power quality – the monitoring and regulation of voltage fluctuations, frequency disruptions, and harmonic distortions, 2. bridging power – short-term power supply for critical demands, often used to cover time periods in which emergency generators are powering up, 3. energy management – energy storage on a scale to support a facility/campus for extended periods of time. These systems can be responsive to utility demand programs and time-of-use rates to cut peak demand costs.
This presentation will include the technical properties of current storage systems, including flywheel, compressed air, and various battery technologies. The technical and market barriers associated with distributed storage, along with proposed paths for resolving said barriers, will also be discussed.
Nanowire battery1
This document discusses nanowire batteries as an improvement over traditional lithium-ion batteries. It provides background on primary and secondary batteries, common battery types such as zinc-carbon and alkaline, and advantages of lithium-ion batteries like high energy density. The document then discusses how nanotechnology can be used to improve lithium-ion batteries by using silicon nanowires for the anode instead of graphite. Silicon can store more lithium than graphite but tends to fracture during charging/discharging. Nanowires prevent fracturing even as the silicon expands and contracts. The document concludes by suggesting that if battery technology improved at the same rate as computer chips, car batteries would be the size of a penny.
Nanowire battery
This document summarizes a seminar presentation on silicon nanowire batteries. It begins by distinguishing primary and secondary batteries. It then discusses common battery types like lithium-ion and highlights advantages like higher energy density but also disadvantages like being more expensive. The document introduces silicon nanowires as a potential anode material with 10 times the energy density of graphite. It describes experiments showing silicon nanowires can accommodate volume changes during charging without degradation. While silicon nanowire batteries offer promising performance benefits, challenges around mass production and lifetime must still be addressed before they can widely replace conventional batteries.
Lattice Energy LLC - IBM and JCESR Tap the Brakes on Lithium-air Battery Rese...
Two major research organizations, IBM and JCESR, have reduced or stopped their research into lithium-air batteries. IBM's director of battery research has changed his view on lithium-air batteries and now favors researching sodium-air batteries instead due to challenges with lithium-air batteries meeting cost targets for electric vehicles. Around the same time, JCESR dropped its lithium-air battery project entirely due to challenges that were too difficult to resolve. While lithium-air research continues at some organizations, two major players have stepped back from the technology.

E-mobility | Part 2 - Battery Technology & Alternative Innovations (English)
Today, 60% of electric vehicles (EVs) are powered by lithium-ion batteries (LIBs) due to its efficiency, high power-to-weight ratio and flexibility to allow chemical alterations. As the EV industry gains steam, supply chain and design challenges are spurring battery manufacturers to explore alternatives.
Some of the alternative battery technologies include lithium-iron phosphate (LFP), lithium-sulfur battery (LSB) and sodium-ion battery (SIB). Besides LFP, LSB and SIB, solid-state batteries (SSBs) are touted as a forerunner for the next-generation battery technology.
Despite these advancements, the current speed of innovation is not accelerating fast enough to meet the demands of the rapidly growing EV sector. This presents opportunities in areas such as battery design and securing the supply chain locally via vertical integration.
As the world welcomes green mobility, commercializing battery technology will be imperative to drive global EV adoption. Given the increased push for battery development and innovation, we believe that it’s only a matter of time before supply catches up with demand.

Ad
This document summarizes a research paper on a new method for producing hydrogen from water using sunlight and a cobalt catalyst. The method uses a silicon solar cell integrated with a cobalt-phosphate catalyst to split water into hydrogen and oxygen when exposed to sunlight. This is an improvement over previous methods that required expensive materials like platinum and operated only in basic solutions, as the cobalt catalyst works under neutral pH conditions. The researchers demonstrated that their new system is able to use most of the solar cell's generated potential for water splitting. While still a proof-of-concept, it shows promise as a cheaper way to produce hydrogen using water and sunlight.

Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.
Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

Lithium air battery
- 2. LOGO Battery 500 Project An initiative started by IBM in 2009 to produce a battery capable of powering a car for 500 miles. In IBM’s lithium-air battery, oxygen is reacted with lithium to create lithium peroxide and electrical energy. When the battery is recharged, the process is reversed and oxygen is released. Conventional batteries are completely self- contained, and the oxygen used in an lithium-air battery obviously comes from the atmosphere, and so the battery itself can be much lighter.
- 3. LOGO The main thing is that lithium-air energy density is a lot higher than conventional lithium-ion batteries: The max energy density of lithium-air batteries is theorized to be around 12 kWh/kg, some 15 times greater than li-ion — and more importantly, comparable to gasoline.
- 4. LOGO
- 5. LOGO
- 6. LOGO
- 7. LOGO How it works: During discharge (driving), oxygen from the air reacts with lithium ions, forming lithium peroxide on a carbon matrix. Upon recharge, the oxygen is given back to the atmosphere and the lithium goes back onto the anode. The battery is forming lithium peroxide Li2O2. Other phases like Li2O also exist which store even more Li atoms (i.e. energy) per molecule. The large volume required for an li-air battery is because of the large surface area required to take in oxygen. The point of the IBM approach is that they have reduced the volume required by increasing the surface area using nano materials in a three-dimensional lattice.
- 8. LOGO Lithium-air batteries aren’t a new idea: They’ve been mooted since the 1970s, but the necessary technology was well beyond the capabilities of then-contemporary material science. Today, with graphene and carbon nanotubes and fancy membranes coming out of our ears, it seems IBM — with assistance from partners Asahi Kasei and Central Glass — now has the materials required to build a lithium-air battery. There is a video embedded below that details the electrochemical process of an li-air battery.
- 9. LOGO The reason we are not using these magical, breathing batteries right now is because they are also chemically unstable, and as of right now, frequent recharges completely destroy the battery life. The researchers discovered that the oxygen is also reacting with in-turn depletes the electrolytic solvent, a conducting solution that moves Li-ions between the electrodes and regulates the chemical reaction.
- 10. LOGO Now researchers collaborating between IBM's Almaden laboratories and Zurich research labs in Switzerland think they have found an alternative electrolytes that won’t react to the air. If everything turns out as promising as it seems, the scientists predict they will have a working prototype by 2013 and a commercial battery by 2020.
