“…23 For the non-ThPs, the processing efficiency and capacity are far from conventional industrial-scale satisfaction. Increasing discharge and/or handling volume generally sacrifices discharge uniformity, 228,229 resulting in uneven physiochemical reactivity distribution and unsatisfactory reaction selectivity. Second, the lack of reliable and highly controllable power sources, which allow for a high-power input, low energy loss, and sufficient lifetime under different surrounding conditions, is a significant roadblock.…”

Plasma‐electrified up‐carbonization for low‐carbon clean energy

Low-value, renewable, carbon-rich resources, with different biomass feedstocks and their derivatives as typical examples, represent virtually inexhaustive carbon sources and carbon-related energy on Earth. Upon conversion to higher-value forms (referred to as "up-carbonization" here), these abundant feedstocks provide viable opportunities for energy-rich fuels and sustainable platform chemicals production. However, many of the current methods for such up-carbonization still lack sufficient energy, cost, and material efficiency, which affect their economics and carbon-emissions footprint. With external electricity precisely delivered, discharge plasmas enable many stubborn reactions to occur under mild conditions, by creating locally intensified and highly reactive environments. This technology emerges as a novel, versatile technology platform for integrated or stand-alone conversion of carbon-rich resources. The plasma-based processes are compatible for integration with increasingly abundant and cost-effective renewable electricity, making the whole conversion carbon-neutral and further paving the plasma-electrified upcarbonization to be performance-, environment-, and economics-viable.Despite the chief interest in this emerging area, no review article brings together the state-of-the-art results from diverse disciplines and underlies basic mechanisms and chemistry underpinned. As such, this review aims to fill this gap and provide basic guidelines for future research and transformation, by providing an overview of the application of plasma techniques for carbon-rich resource conversion, with particular focus on the perspective of discharge plasmas, the fundamentals of why plasmas are particularly suited for upcarbonization, and featured examples of plasma-enabled resource valorization. With parallels drawn and specificity highlighted, we also discuss the technique shortcomings, current challenges, and research needs for future work.

“…[4] Additionally, SDBDs can be made from flexible materials [5] , [6] , [7] allowing the electrodes to conform to more complex 3-dimensional geometries, which can be beneficial to create a constant treatment distance when the desired treatment substrate is not flat such as in the treatment of produce. [4] These advantages have resulted in SDBDs gaining interest for numerous applications, including bacteria inactivation, [8] plasma medicine, [9] flow control, [10] pollution remediation, [11] and in-package plasma processing for fresh produce decontamination.

Surface Dielectric Barrier Discharges (SDBDs) have been gaining interest in recent years for numerous applications. One of the advantages of SDBDs is their scalability and flexibility of materials used, allowing larger electrodes than simple linear electrodes investigated in earlier works. This paper seeks to elucidate the properties of more complicated SDBD geometries utilizing differing repeated lattice structures. Voltage and current traces, optical emission spectroscopy, digital imaging, and numerical analysis are used to analyze the electrodes. Reduced electric fields obtained through optical emission spectroscopy and the total power deposited into the plasma are presented. The reduced electric field is not significantly affected by increasing applied voltage, but minor variations could be observed due to the geometry of the electrode lattice structures. Finally, it was observed that plasma power is not a simple linear relationship in these more complicated lattice structures. Smaller lattice structures were observed to have lower energy deposited per period.
