Nanomaterial and Laser Induced – Breakdown Spectroscopy (LIBS)

JOURNAL of UNIVERSITY of BABYLON for Pure and Applied Sciences, 2019
In the present work, the optical emission spectra of Nano- Copper (Cu) plasma have been recorded and analyzed using the laser induced breakdown spectroscopy technique (LIBS). The emission line intensities and plasma parameters were investigated as a function of laser energy. The electron number density (ne) and electron temperature (Te) were determined

Corundum Discovered by SuperCam and the Perseverance Rover at Jezero Crater, Mars

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Mars is primarily composed of mafic mineral assemblages and their alteration products, but small, scattered rocks strewn across the landscape offer clues to greater petrological diversity. While traversing the Jezero crater rim, the Perseverance rover encountered several plagioclase‐rich light‐toned float rocks.

Engineering Strategies to Suppress Thermal Runaway Propagation in Lithium‐Ion Battery: Mechanisms, Metrics, Materials, and Evaluation Methods

Advanced Science, Volume 13, Issue 44, 7 August 2026.
Thermal runaway propagation can transform a single‐cell failure into a system‐level hazard in lithium‐ion battery packs. This review clarifies how heat transfer, gas venting, combustion, and configuration govern cell‐to‐cell failure, and links measurable metrics, pathway‐oriented suppression materials, and experimental/modeling tools to guide safer ...

Comparative Electrochemical and Mechanical Investigation of Alkali Ion Insertion into Berlin Green

Batteries &Supercaps, Volume 9, Issue 8, August 2026.
Sequential Li+, Na+, and K+ ion insertion into the same Berlin Green electrode reveals its ion‐tolerant structure and stable morphology, and distinct insertion mechanisms for K+. Stable electrode materials with reversible ion insertion/extraction are central to developing sodium‐ and potassium‐ion batteries as lithium‐ion alternatives.

Direct Recycling of Nickel Manganese Cobalt Oxides: Impact of Shear Milling on Physicochemical and Electrochemical Performance

Batteries &Supercaps, Volume 9, Issue 8, August 2026.
The first step of the direct recycling process of lithium‐ion battery (LIB) cathodes is investigated through shear milling of NMC622 materials. An excessive milling energy could alter particle size and induce crystalline microstrains, leading to electrochemical performance loss.
