We investigate if the functionality of spin crossover molecules is preserved when they are assembled into an interfacial device structure. Specifically, we prepare and gold nanoparticle arrays, which room-temperature introduced, more precisely, [Fe(AcS-BPP)2](ClO4)2, where AcS-BPP = (S)-(4-{[2,6-(dipyrazol-1-yl)pyrid-4-yl]ethynyl}phenyl)ethanethioate (in short, Fe(S-BPP)2). combine three complementary experiments to characterize molecule-nanoparticle structure in detail....
Plasma technology, combined with activation on surfaces, is a novel way to convert CO<sub>2</sub>using green electricity.
Charge transport in networks of nanoparticles linked by molecular spacers is investigated. Remarkably, the regime where cotunneling dominates, signature a device strongly enhanced. We demonstrate that resistance ratio identical with different increases dramatically, from an initial value 50 up to 105, upon entering regime. Our work shows intrinsic properties can be amplified through nanoscale engineering.
This paper focuses on how the electron temperature and other plasma properties affect optical emission CO2 conversion in plasma. Such plasma-mediated reactions can enable efficient reuse. We study CO plasmas generated by inductively coupled radiofrequency power (30–300 W) at low pressures (6–400 Pa). By varying argon admixture, we effect of temperature, Te, using spectroscopy, mass spectrometry, electrical probe measurements. Importantly, observe several parameters simultaneously:...

Changing the temperature ionic strength during hydrothermal treatment, were tailored sizes aspect Amino-modified polyisobutylene molecules grafted onto following convenient new route involving freeze-drying. Organic dispersions in toluene particles with largest size highest ratio. The colloidal this way showed...
Dry reforming of methane (DRM) is a challenging process wherein reacts with CO 2 to give syngas. This reaction strongly endothermic, typically requiring temperatures higher than 500 °C. Catalysts can be used, but the high (which are thermodynamic requirement) often lead catalyst deactivation. Herein, from another conceptual direction approached, using low‐power radio frequency inductively coupled plasma (RF‐ICP). It demonstrated that this system conversions and at near‐ambient temperatures....
The synergy between catalysis and plasma chemistry often enhances the yield of chemical reactions in plasma-driven reactors. In case CO2 splitting into CO O2, no positive synergistic effect was observed earlier studies with reactors, except for dielectric barrier discharges, that do not have a high efficiency. Here, we demonstrate introducing metal meshes radio frequency-driven reactors increases relative reaction by 20%–50%, while supported oxide catalysts same setups effect. We attribute...
Aqueous Zn–CO 2 battery possesses a large theoretical capacity of 820 mAh g -1 (5855 cm -3 ) and high safety, showing unique position in carbon neutrality and/or reduction energy conversion storage, which has developed rapidly recent years. However, obstacles such as low value-added products, current density, overvoltage, finite cycles impede its practical application. Cathode catalysts, key component, have significant influence on gas cell performance. Despite many updated papers cathode...
The photocatalytic efficacy of a novel mononuclear rhenium(I) complex in CO2 reduction is remarkable, with turnover number (TONCO) 1517 three hours, significantly outperforming previous Re(I) catalysts. This complex, synthesized via substitution reaction on an aromatic ring to form bromo-bipyridine derivative, L1 = 2-Bromo-6-(1H-pyrazol-1-yl)pyridine, and further reacting [Re(CO)5Cl], results the facial-tricarbonyl [ReL1(CO)3Cl] (1). light green solid was obtained 80% yield thoroughly...

CO2 decomposition is a very strongly endothermic reaction where high temperatures are required to thermally dissociate CO2. Radio frequency inductively-coupled plasma enables selectively activate and at room temperature. Tuning the flow rate of radio gives yields CO under mild conditions. Finally discovery catalytic effect has been demonstrated for dissociation that shows significant increase yield by metallic meshes. The meshes become catalysts exposure recombination atomic O O2, thereby...
We prepare and investigate two-dimensional (2D) single-layer arrays multilayered networks of gold nanoparticles derivatized with conjugated hetero-aromatic molecules, i.e., S -(4-{[2,6-bipyrazol-1-yl)pyrid-4-yl]ethynyl}phenyl)thiolate (herein S-BPP), as capping ligands. These structures are fabricated by a combination self-assembly microcontact printing techniques, characterized electron microscopy, UV–visible spectroscopy Raman spectroscopy. Selective binding the S-BPP molecules to through...
Electrodeless Low-Frequency (LF)/Radio-Frequency (RF) plasma sources often suffer from low power coupling efficiencies due to the lack of overlapping field with dynamic load. However, supplies for these typically have very high (>90%) and are more cost-effective compared microwave sources. If efficiency can be increased, offer a competitive technology sustainable electrification chemical industry. This work experimentally investigates five methods, applied toroidal CO2 plasmas in quartz...
Conversion of CO2 into CO with electricity is a straightforward method to convert intermittent sustainable storable chemical energy. Despite much research efforts worldwide, it has not yet simultaneously achieved acceptable conversion and energy efficiency. Here we demonstrate that the Boudouard reaction, + C → 2CO, driven by thermal plasma allows exceeding 95% electrical efficiencies 70% for production, which are higher than seen so far conventional method. The improved performance benefit...
