An ultrathin coating was developed that contradicts a physics phenomenon of materials related to thermal radiation: The hotter an object gets, the brighter it glows. The new coating is engineered from samarium nickel oxide, a unique tunable material. The coating “breaks” the relationship between temperature and thermal radiation; essentially, there is a temperature range within which the power of the thermal radiation emitted by the coating stays the same
A collaboration co-led by an Oregon State University chemistry researcher is hoping to spark a green battery revolution by showing that iron instead of cobalt and nickel can be used as a cathode material in lithium-ion batteries
This specification covers the requirements for electroless nickel with phosphorus deposited on various materials
While Daimler Truck and Paccar are pursuing LFP battery cells, Volvo Trucks employs lithium-ion batteries in which lithium nickel cobalt aluminum oxide (NCA) is used as the cathode — for now anyway. The Swedish truck maker is continuously exploring other battery technologies
A Columbia Engineering team has published a paper in the journal Joule that details how nuclear magnetic resonance spectroscopy techniques can be leveraged to design the anode surface in lithium metal batteries. The researchers also present new data and interpretations for how this method can be used to gain unique insight into the structure of these surfaces
Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new lithium metal battery that can be charged and discharged at least 6,000 times — more than any other pouch battery cell — and can be recharged in a matter of minutes

This procurement specification covers tubular-shaped, coiled spring pins made of a corrosion resistant nickel base alloy of the type identified under the Unified Numbering System as UNS N07718
This document defines the requirements for weld fittings and machine weldments using an orbiting welding head suitable for use on cold worked 3AL-2.5V titanium, 21Cr-6Ni-9Mn CRES, and 718 nickel alloy tubing. Fitting standards covered by this specification include non-separable welded elbow, tee, and reducer fittings, and reconnectable 24-degree cone fittings, such as sleeves and unions
Fly ash is a light byproduct produced when pulverized coal is burnt in suspension-fueled furnaces in power plants. Separating the recovered fly ash from the exhaust gases. Due to its distinct physical and chemical properties, it is utilized in a wide variety of industrial and building applications. These applications include the production of cement and concrete, the stabilization of liquid waste, and hydraulic mining backfill. Fly ash has the potential to enhance the physical and mechanical properties of aluminum castings, as well as reduce their costs and increase their densities, all while lowering their prices. This research investigated the effect of fly ash incorporation on the mechanical properties of the aluminum casting alloy ZA8. Investigated were the cast and heat-treated varieties of unreinforced ZA8 and its metal matrix composite of 15% ferrous, 20% nickel, 10% fly ash, and 10% magnesium carbide. According to the results, the quantity of fly ash in the melt affected the
A team from Chalmers University of Technology has succeeded in observing how the lithium metal in the cell behaves as it charges and discharges. The new method may contribute to batteries with higher capacity and increased safety in our future cars and devices
Researchers at Chalmers University of Technology, Sweden, have created a new and efficient way to recycle metals from spent electric vehicle (EV) batteries. The method allows recovery of 100 percent of the aluminum and 98 percent of the lithium in EV batteries. At the same time, the loss of valuable raw materials such as nickel, cobalt, and manganese is minimized. No expensive or harmful chemicals are required in the process because the researchers use oxalic acid – an organic acid that can be found in the plant kingdom
Engineers have made progress toward lithium-metal batteries that charge as fast as an hour. This fast charging is thanks to lithium metal crystals that can be seeded and grown — quickly and uniformly — on a surprising surface. This new approach, led by University of California San Diego engineers, enables charging of lithium-metal batteries in about an hour, a speed that is competitive against today’s lithium-ion batteries
“Adjacent” strategies such as improving vehicle efficiency and advancing promising chemistries can mitigate the risks associated with today's favored battery materials. Battery electric vehicle (BEV) adoption is taking off for a variety of reasons. Battery cost per kWh of energy stored has dropped 10-fold since 2010. Driving range has increased, making range anxiety less of a concern, particularly for households having Level 2 charging and several vehicles. Government regulations in key vehicle markets and automakers rethinking the electrical architecture to support software-defined vehicles also are stimulating an expanding choice of consumer EVs. With increased EV adoption comes concern for the environmental and human rights impact associated with battery materials mining and processing as well as national-security concerns. Supply volatility, given the huge investments and long-term return, make battery production susceptible to price spikes, as seen in 2022 with lithium and nickel
This specification covers an aircraft-quality, low-alloy steel in the form of bars, forgings, and forging stock
Electroplating is a process whereby an object is coated with one or more relatively thin, tightly adherent layers of one or more metals. It is accomplished by placing the object to be coated on a plating rack or a fixture, or in a basket or in a rotating container in such a manner that a suitable current may flow through it, and then immersing it in a series of solutions and rinses in planned sequence. The advantage to be gained by electroplating may be considerable; broadly speaking, the process is used when it is desired to endow the basis material (selected for cost, material conservation, and physical property reasons) with surface properties it does not possess. It should be noted that although electroplating is the most widely used process for applying metals to a substrate, they may also be applied by spraying, vacuum deposition, cladding, hot dipping, chemical reduction, mechanical plating, etc. The purpose for applying an electroplate and the metals used for various

Among the limitations of electric vehicles (EVs) is the lack of a long-lasting, high-energy-density battery that reduces the need to fuel up on long-haul trips. The same is true for houses during blackouts and power grid failures — small, efficient batteries able to power a home for more than one night without electricity don’t yet exist. A major issue is that while rechargeable lithium metal anodes play a key role in how well this new wave of lithium batteries functions, during battery operation, they are highly susceptible to the growth of dendrites — microstructures that can lead to dangerous short-circuiting, catching on fire, and even exploding
