![]() 13–15 The structural stability is likely to be improved by Mn 4+, which is electrochemically inactive. 11,12 Mn is involved in the structural and thermal stability of the NMC cathode material. 9,10 Also, the presence of Co 3+ may suppress structural distortion resulting from the Jahn–Teller effect of Ni 3+. 7,8 Co can partially contribute to capacity achievement, but mostly it improves the rate capability of the battery. Ni is the key element that enables high capacity of the battery by a two-stage redox reaction between Ni 2+/Ni 3+ and Ni 3+/Ni 4+. 4–6 In addition, cathodes containing mixed transition metals of Ni, Mn, and Co can provide synergic advantages over a single transition metal oxide cathode. 1–3 Since the last decade, attention has been paid to layered transition metal oxide batteries, which can be represented by the formula of LiNi xCo yMn 1− x− yO 2 (NMC, x > 0 and y > 0), owing to their high discharge capacity (<200 mA h g −1), high energy density, and lower cost compared to conventional LiBs ( e.g., LiCoO 2). Introduction Lithium-ion batteries (LiBs) have attracted great interest as an energy storage system for various applications ranging from mobile devices to electric vehicles and energy storage stations for solar cells. Energy level alignment itself is likely to be the key process that leads to the active formation of unstable CEI layers on charge–discharge. Hence, a downward band bending could be depicted based on the work function and the energy level difference between the Fermi level ( E F) and the valence band maximum ( E VBM). Negatively charged elements tend to be present at the close surface of the cathode, while the positively charged Li + migrates from the cathode to the CEI layer. Herein, we empirically identify the energy level band bending of a Ni-rich NMC cathode ( i.e., Li(Ni 0.5Mn 0.3Co 0.2)O 2) with the visual evidence of Li + transfer from the electrode to the CEI layer (adsorbate). The CEI layer consists of various by-products ( e.g., LiF, Li 2CO 3, ROLi, and ROCO 2Li (R: alkyl group)) decomposed from redox reactions between the cathode and the electrolyte, which can lead to dramatic capacity fading and stability issues. The analysis attributed electrochemical features from both species, including the high voltage profiles from the NMC and the good pulse performance from the LFP.Cathode–electrolyte interphase (CEI) formation between the cathode and the electrolyte is a critical factor that determines the stability of lithium-ion batteries (LiBs). The EIS analysis allowed cell kinetics and transfer mechanisms to be assigned and compared between the two chemistries. Blended cathodes were made with 70% NMC and 30% LFP. The coin cells tested had NMC, LFP, or a blend of NMC/LFP as the primary material in the cathode. This allows any performance effects from the anode to be eliminated. This experiment focused specifically on the cathode by assembling half-cells, which cycle the cathode against pure lithium. The research conducted focuses on testing cathode materials by performing electrochemical and rate testing followed by electrochemical impedance spectroscopy (EIS). For this reason, blends of NMC and LFP can impart the high energy density of NMC, with the safety and pulsed performance of LFP. Lithium-iron-phosphate (LFP) is less common due to its lower voltage range but exhibits higher safety and better high rate performance, especially during pulses of high current demand. Lithium-nickel-manganese-cobalt-oxide (NMC) is a favored cathode active material in EVs because of its high energy density and high voltage limits, with the challenge of inferior high rate performance than other chemistries. Their high power and energy capability provides power for small consumables, such as watches, up to electric vehicles (EVs) and grid scale energy storage systems. The need for renewable energy is rapidly increasing, and the optimization of lithium-ion batteries is critical for the industry. ![]()

Those agencies included ATF, the Capitol Police, FBI, Marshals Service, Park Police, and U.S. “Six agencies told us that they used images from these events to conduct facial recognition searches during May through August 2020 to assist with criminal investigations.” ![]() “Following the death of George Floyd while in the custody of the Minneapolis, Minnesota police department on May 25, 2020, nationwide civil unrest, riots, and protests occurred,” GAO wrote. But agencies also leveraged different types of face-reading technology across use cases after those dates-and particularly in times of national tension. The FBI, Secret Service, and Park Police were among other agencies to use Clearview’s technology during the period GAO reviewed. “In Figure 3, we were hoping the visual would provide readers a greater understanding of how systems that federal agencies use can have different numbers of photos,” Goodwin said. Clearview AI’s system outnumbers the rest, encompassing more than 3 billion photos. GAO’s review included a visual chart demonstrating facial recognition technology systems used by those federal law enforcement agencies and the number of photos in each system. U.S.-based facial recognition company Clearview AI has spurred concerns about privacy and anonymity and faced lawsuits and legal complaints around its data collection and practices. The Customs and Border Protection, Marshals Service, and Bureau of Alcohol, Tobacco, Firearms and Explosives, for example, reported using systems owned by other federal entities state, local, tribal or territorial entities Vigilant Solutions Clearview AI and other non-government providers during the time GAO examined. ![]() In addition, they detailed an array of federally-built options and shed light on who deploys what. The systems could “include hundreds of millions or billions of photos of various types,” GAO wrote. GAO’s audit unfolded from August 2019 to June 2020, Goodwin said.Īccording to the public document, 20 of the 42 agencies that participated confirmed that they owned a system with facial recognition technology or used another owned by an external entity during a specific period. Specifically, GAO examined the ownership and use of facial recognition technology by those entities, the types of activities they use the technology for, and how they track using systems owned by those outside the government. But the June-dated document “omits sensitive information about agency ownership and use of facial recognition technology,” according to GAO.įor the study, the watchdog sent a survey to those 42 federal law enforcement-aligned agencies, interviewed agency officials, and reviewed documents from some organizations. The report is a public version of a more sensitive document sent to Congress members in early April. “In addition, by assessing the risks of using these systems, including privacy and accuracy-related risks, agencies will be better positioned to mitigate any risks to themselves and the public.” “By implementing a mechanism to track what non-federal systems are used by employees, agencies will have better visibility into the technologies they rely upon to conduct criminal investigations,” officials recommended in the report. ![]() “A goal of this project was to provide the ‘lay of the land’ in terms of federal law enforcement’s use of facial recognition technology,” she told Nextgov Tuesday.īut GAO found 13 of 42 agencies surveyed do not have a firm grasp of all the non-government facial recognition tools their teams use and therefore cannot fully assess accompanying dangers. Cory Booker, D-N.J., Chris Coons, D-Del., Edward Markey, D-Mass., and Ron Wyden D-Ore., asked GAO to steer the study. Jerry Nadler, D-N.Y., and Carolyn Maloney, D-N.Y., and Sens.

In-depth discussion of O 2 catalysts for air electrodes and progress of binder-free air electrodes for ZABs are presented in the following based on three major modification strategies: defect engineering, cation/anion regulation in multi-components transition metal compounds, and single or multi-heteroatom doping in carbon materials (metal-free and metal-based material). The first part describes the fundamentals of an ideal air electrode with its corresponding oxygen electrochemical reactions and typical bifunctional O 2 catalysts. This review highlights the structural features essential to satisfy the design of the cathode compartment of ZABs and presents the associated factors that drive the oxygen reactions in the air electrode based on the relationship between the intrinsic activities of bifunctional O 2 catalysts and the collective strategies employed to modify the electronic structure of such electrocatalysts. To develop a structural design that could provide accessible active sites to oxygen, electrolyte, and electron, it is necessary to modify the overall structure of an air electrode, which is considered as the most significant and complicated part of Zn–air batteries (ZABs). ![]() ![]() Please redirect your content to the daily gossip megathread, Teatime with Popheads.

![]() ![]() Apparently, the species was infiltrating the Beta Quadrant from Fluidic Space, focusing their sabotage not on the Federation, but on the Klingons, through infiltrating and manipulating the Gorn Hegemony. The few Klingon investigation into the cause of the Gorn attacks revealed the influence of Species 8472, also known as the Undine. When the Nausicaans allied with the Gorn, the Klingons partnered with the Orions. This led to swift retaliation that escalated to a war between the Gorn and Klingons. Meanwhile, the Gorn Hegemony attacked and destroyed several Klingon ships. When the Federation protested, the Klingons responded unfavorably, which weakened the Khitomer Accords and the alliance between those powers. The Klingons invaded Romulan space, taking advantage of their longtime enemies’ weakness. In the timeline of Star Trek Online, following the Hobus supernova that destroyed Romulus, the entire region was destabilized. Because players want to fight and defeat the Borg, that threat could have not be destroyed by the virus seen at the end of Star Trek Voyager, nor could they have been defeated following a mass invasion, such as presented in the Destiny novels timeline. The 25th CenturyĪs a combat focused video game, the 25th Century of Star Trek Online is designed for maximum conflict, to justify players freely attacking Klingon and Romulan vessels and PvP between players of the Federation and Klingon factions.

The breathing of radon radioactive progenies with ambient air can caused kidney infections, lung cancer, and skin. Air which human breath it, is the primary source of radioactive dose that enter the human body, and as well as the main source of radon that found in the earth’s atmosphere generated by the automatic decomposition of uranium. Also drinking water and fluids can contain low dose. Plants contain radioactive isotopes initiating from the soil, that absorbed it with other natural substances. When the human are eating plants, meat of animals or drinking any fluids (tea, coffee, water, and juice), he can be contaminated with different radioactive isotopes (Ra-226, Rn-222, U-238, etc). Radiation contamination which are existing in water and soil can be transported by the food chain to humans and animals. When human respire or inhale radon and its progenies along with the normal air, most of the radon is exhaled, its progenies become record to the internal walls and membranes of our respiratory system and continue producing steady damage because of their alpha activity. These daughters’ yields are hard and have a trend to relate themselves to aerosols in around air. Radon progenies are Po-218 and Po-214 emit alpha particles.

However, the chemical manner of radium is as like as calcium, therefore radium absorbed to blood from lungs or gastrointestinal tract (GI-tract) or follows the manner of calcium and is mainly deposited in bone. Radium-226 in the environment is broadly spreading, and usually presented in several concentrations in soils, water, foods, sediments and rocks. The measurements of radon and radium concentrations in foods are main for the health safety. Uranium daughters (Ra-226 and Rn-222) are mainly have a major health risk. If this will happen then a person will be susceptible to skin cancer. Health effects from external exposure are limited to skin contact and uranium object would have to stay in direct skin contact for more than 250 h. Uranium has been repeatedly claimed to be the cause of cancer, leukemia and other health effects. Once ingested uranium is highly toxic and attacks the inner organs such as kidneys, lungs and heart. Uranium ore is relatively harmless, as long as it remains outside of the body. Uranium and its compounds are carcinogenic and highly toxic, which causes acute kidney failure and death in high concentrations as well as brain, liver and heart diseases. Naturally, Uranium exists as three isotopes 234U, 235U and 238U with a relative abundance of 0.0055, 0.720 and 99.29%, respectively. It is a relatively reactive element which combines with non–metals such as oxygen, sulfur, chlorine, fluorine, phosphorus, and bromine. Uranium occurs naturally in low concentrations (a few parts per million) in soil, rock, surface water, and groundwater. After study it is found that the average values of annual effective dose in mSv/y are within the recommended limit of ICRP values except its values for cornstarch and sugar are relatively high, and there are a wide range of variations in the values of transfer factor for Rn-222, and Ra-226 for all types. Analysis the concentrations of Radon-222 and Radium-226 for different types of household foods samples are very substantial for realizing the comparative contributions of specific substances to the whole radon content set within the human body. Salt analysis is very important due to its high consumption by the population and for its medicinal use. Many food items contain natural sources of salt. This chapter show the natural of radioactivity as alpha particle which produce from decaying of radium to radon so in this chapter describe the radon in some types of household food (coffee, tea, powder milk, rice, flour, cornstarch, and powder coconut) and different types of salt by using Solid State Nuclear Track Detectors (SSNTD), were analyzed by closed-can technique (CR-39). ![]() |
