A Practical Guide to Heterogeneous Catalysis in Hydrocarbon Transformations

open access: yesChemistry – An Asian Journal, EarlyView.
A focused overview of the catalytic processing of hydrocarbons to transform them into more valuable compounds is presented. This work is intended to assist BSc, MSc, and PhD students, as well as junior researchers, in selecting and performing appropriate heterogeneous catalytic processes for specific heterogeneous catalytic reactions.

JWST Imaging of the Closest Globular Clusters—VI. The Lowest‐Mass Objects in M 4 and the Galactic Bulge

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT We present James Webb Space Telescope observations of M 4—the closest globular cluster—that probe the lower Main Sequence down to the hydrogen‐burning limit. The unveiled stellar sequence reaches much fainter luminosities than previously possible, revealing a few extremely red objects that are consistent with brown dwarfs as cool as Teff∼1000K$

Tailoring Adsorption Properties of Graphitic Surfaces: Toward Improved Anode Materials for Li‐ and Post‐Li Ion Batteries

open access: yesBatteries &Supercaps, EarlyView.
Defects and impurities enable the adsorption of Li and Na on graphitic surfaces and can be used to control the alkali metal (AM) adsorption energy. This can be an effective way for minimizing AM losses during cycling of graphite‐based anode materials. The adsorption of alkali metal (AM) atoms on graphitic surfaces is one of the processes that determine

Enhancing the Energy Density of Zn‐Ion Capacitors Using Redox‐Active Choline Anthraquinone Electrolyte

open access: yesBatteries &Supercaps, EarlyView.
Biocompatible redox electrolytes: The presence of choline chloride in aqueous ZnCl2 electrolyte improves the stability and performance of Zn‐ion capacitor is shown. An enhancement in energy density is achieved by the addition of choline anthraquinone sulphonate redox molecule in the electrolyte. Owing to ease of recyclability, high theoretical capacity
