Carbon Energy, EarlyView.ABSTRACT Biochar has emerged as a useful and adaptable source of carbon for supercapacitor electrodes. Its value comes from the way biomass chemistry, thermal conversion, and activation conditions shape the resulting pore network, surface groups, and degree of carbon ordering.

Recent Progress on Fullerene–Based Functional Materials for Energy Conversion
Carbon Energy, EarlyView.A schematic illustration summarizing the classification, and photo‐/electro‐‐/thermo‐catalysis and energy storage applications of C60 and derivatives. ABSTRACT Efficient energy conversion and environmental protection are still constrained by rapid carrier recombination, unstable interfaces, limited active site, and so on. Owing to the unique electronic

Pulsed electromagnetic gas acceleration [PDF]
Terminal voltage measurements with long cathodes in a high power, quasi-steady MPD discharge show that the critical current for the onset of voltage fluctuations, which was previously shown to be a function of cathode area, approaches an asymptote for ...

Ultra‐High‐Efficiency On‐Chip CO2 Conversion by Nanosecond Self‐Pulsing Micro‐Plasma Devices
Carbon Energy, EarlyView.A micro‐plasma chip with sub‐10‐μm electrode gaps is introduced for efficient CO2‐to‐CO conversion. The device self‐converts a DC power supply into nanosecond pulses, producing field‐emission electrons that vibrationally excite CO2, driving dissociation via the ladder‐climbing mechanism. A scaled‐up chip array achieves 30% single‐pass conversion and 50%

Carbon Energy, EarlyView.A Se‐mediated Co dual‐atom catalyst replaces sluggish oxygen evolution with efficient iodide oxidation in zinc‐air/iodide hybrid batteries. Se‐induced d‐p orbital hybridization optimizes adsorption, enabling a low 0.365 V voltage gap and superior durability, fundamentally overcoming conventional kinetic bottlenecks.

Carbon Energy, EarlyView.Kirkendall‐engineered hollow Ni–Mn hexacyanoferrates feature Ni‐tunable shell thickness and uniform alloying, coupling architectural control with electronic stabilization. Composition–morphology co‐optimization suppresses Mn³⁺‐driven Jahn–Teller distortions and lowers charge‐transfer barriers, enabling rapid Zn²⁺ transport and reversible redox.

Characterization of Propellant Flow and Bias Required to Initiate an Arc Discharge in a Heaterless Hollow Cathode [PDF]
Heaterless hollow cathodes provide an opportunity to reduce complexity and improve reliability in electric propulsion systems. While removal of the heater has little effect on steady-state operation of a hollow cathode, it has a considerable effect on ...
